VMware虚拟机配置任何IP都出现“Windows检测到IP地址冲突”故障的解决

一台VMware虚拟化平台上的虚拟机,配置任意IP都显示“IP地址冲突”,且只有该虚拟机89网段出现此问题,其它网段都正常,主要排查步骤如下:

 nwerr_01

如上图,无论配置89段哪个IP地址,都会出现“Windows检测到IP地址冲突”,且故障只有89网段存在,其它网段正常,如下图

nwerr_02

以为是有ARP病毒,结果排查后不是这个原因,只能查源头,看哪个MAC地址一直与本机IP冲突,开始检查Windows日志,发现日志提示无论更改为哪个IP,都与00-0C-29-04-CF-33这个MAC冲突,如下图所示:

nwerr_03

在核心交换机中查询此MAC,使用dis arp | in 192.168.89.,没有查询到00-0C-29-04-CF-33此MAC地址,如下图所示

nwerr_05

最后发现00-0C-29-04-CF-33这个MAC和上图中的MAC前几位都相同,89段基本都用在VMware虚拟化平台上,故能判断00-0C-29-04-CF-33这个MAC的虚拟机应该也是在此VMware虚拟化平台中运行,通过在ESXi中一台台查看,找到了一台“中标麒麟”的虚拟机为此MAC,如下图:

nwerr_06

进入虚拟机查看,发现lo回环网卡的IP地址为192.168.89.201,不是默认的127.0.0.0/255.0.0.0,如下图

nwerr_07

且ping任意89段中IP都能PING通,怀疑为此原因造成了89段IP在其它虚拟机配置不上去的原因

nwerr_08

故将此虚拟机关机,再在刚才的虚拟机中配置89段的任意IP,发现IP冲突故障消失,可以配置IP,且能PING通网关,如下图。

nwerr_09

综上,本次是由于同网段中一台虚拟机在lo回环网口上配置了相同的89段,而不是127.0.0.1而导致的,将虚拟机关机后,故障现象排除。

8、Centos8上试用开源堡垒机Jumpserver 1.5.6(八):创建用户时使用密码链接并发邮件给用户功能

===================================================================

Jumpserver在创建用户时密码策略支持“生成重置密码链接,通过邮件发送给用户”功能,如下图所示,用户收到邮件后,直接修改成自己的密码即可

jumpserver0221_51

需要启用此功能,需要进行相关设置,具体操作如下:

进入“系统设置”->“基本设置”,在当前站点URL中输入访问地址http://192.168.10.216,Email主题前缀设置为“你好,”,如下图所示

jumpserver0221_52

设置“邮件设置”,如下图,需要配置SMTP主机、端口、账号等

jumpserver0221_53

本案例使用126邮箱,登陆126邮箱,进入设置->POP3/SMTP/IMAP,开启SMTP服务,SMTP地址为smtp.126.com,如下图所示

jumpserver0221_54

服务器地址:
POP3服务器: pop.126.com
SMTP服务器: smtp.126.com
IMAP服务器: imap.126.com

jumpserver0221_56

126邮箱对第三方邮件客户端提供POP3\SMTP\IMAP有授权码要求,开启授权码,如下图

jumpserver0221_55

126邮箱设置好后,开始进行邮件设置

SMTP主机:smtp.126.com
SMTP端口:465
SMTP账号:funpower@126.com
SMTP密码:********
发送账号:funpower@126.com
测试收件人:funpower@qq.com
使用SSL:启用SSL,端口465

如下图,输入内容后点击“测试链接”,显示已发送邮件后,点击“提交”保存。

jumpserver0221_57

点击测试连接,右上角出现已发送消息,如下图

jumpserver0221_58

邮件中收到了TEST测试邮件,说明邮件设置正确。

jumpserver0221_59

接着完成“邮件内容设置”,如下图

jumpserver0221_60

最后,重启服务器,确保设置生效。

进入创建用户界面,输入用户相关信息,在密码策略中选择“生成重置密码链接,通过邮件发送给用户”,点“提交”按扭,如下图所示

jumpserver0221_61

点提交后,正常会收到一封用户创建成功的信,点击信中的密码链接进行密码重置,如下图

jumpserver0221_62

重置,设置新密码

jumpserver0221_63

使用新设置的密码进入管理系统

jumpserver0221_64

至此,创建用户完成。

8、Centos8上试用开源堡垒机Jumpserver 1.5.6(八):创建用户时使用密码链接并发邮件给用户功能

===================================================================

服务器出现硬件故障或维护等原因需要关闭或重启jumpserver服务器,而重启后,由于一些程序不是开机自动启动,需要手工,具体重启后恢复操作如下:

1、检查防火墙及SELinux状态

正常在安装时这两个功能为关闭状态,检查是否为关闭状态:

[root@localhost ~]# getenforce
Disabled
[root@localhost ~]#
[root@localhost ~]# firewall-cmd –state
not running
[root@localhost ~]#
[root@localhost ~]#

jumpserver0221_38

如上所示,检查都为关闭状态。

2、检查redis、mariadb、nginx启动状态

由于redis、mariadb、nginx这三个程序在安装时是启用开机自启动模式,故正常应该都为运行状态,检查如下:

jumpserver0221_39

如上所示,redis、mariadb、nginx都为运行中,状态正常。

3、检查jumpserver程序

jms没有设置为自启动,需要手工启动,首先进入python环境:

[root@localhost ~]# source /opt/py3/bin/activate
(py3) [root@localhost ~]#
(py3) [root@localhost ~]#

然后进入jumpserver程序目录/opt/jumpserver,使用./jms status –d检查程序是否启动,操作如下:

(py3) [root@localhost ~]# cd /opt/jumpserver
(py3) [root@localhost jumpserver]#
(py3) [root@localhost jumpserver]# ls
Dockerfile  LICENSE  README.md  README_EN.md  Vagrantfile  apps  build.sh  config.yml  config_example.yml  data  docs  entrypoint.sh  jms  logs  requirements  run_server.py  tmp  utils

daphne is stopped
(py3) [root@localhost jumpserver]#

jumpserver0221_40

如上,显示都为stopped,未启动,故页面也无法打开,如下:

jumpserver0221_42

使用./jms start –d启动jumpserver程序,如下:

(py3) [root@localhost jumpserver]# ./jms start -d

jumpserver0221_41

完成启动,再次打开主界面http://192.168.10.216,显示正常,如下:

jumpserver0221_43

jumpserver正常后,使用admin用户登陆管理主界面,进入“会话管理”->”终端管理”,如下图,在线状态栏中显示红色小圆点,即为未在线,说明koko和guacamole没有启动

jumpserver0221_45

检查koko和guacamole镜像,如下,说明镜像存在:

(py3) [root@localhost ~]# docker images
REPOSITORY                                         TAG     IMAGE ID       CREATED       SIZE
dockerhub.azk8s.cn/wojiushixiaobai/jms_guacamole   1.5.6   af71674d07a4   2 weeks ago   678 MB
dockerhub.azk8s.cn/wojiushixiaobai/jms_koko        1.5.6   2561f1397767   2 weeks ago   367 MB
(py3) [root@localhost ~]#
(py3) [root@localhost ~]#

使用docker ps查看运行中的容器,发现没有运行中的容器,如下:

(py3) [root@localhost ~]# docker ps
CONTAINER ID  IMAGE  COMMAND  CREATED  STATUS  PORTS  NAMES
(py3) [root@localhost ~]#
(py3) [root@localhost ~]#

使用docker ps -a查看所有创建的容器(包括未运行的容器),如下:

(py3) [root@localhost ~]# docker ps -a
CONTAINER ID  IMAGE                                                   COMMAND          CREATED      STATUS                          PORTS                                             NAMES

(py3) [root@localhost ~]#
(py3) [root@localhost ~]#

如上所示,发现STATUS中状态为Exited,正常应该为up,应该是容器没有启动,手工启动koko和guacamole,操作如下:

(py3) [root@localhost ~]# docker start 9107b7603bf2
9107b7603bf25c48bb939907882591cee524e22bd5c399781694863152fae72f
(py3) [root@localhost ~]#
(py3) [root@localhost ~]#
(py3) [root@localhost ~]# docker start 769148c0cec1
769148c0cec1cc8a6b227e9946f48613e3670c33b347862ae07e53d6b2e1ac99
(py3) [root@localhost ~]#
(py3) [root@localhost ~]#

start后面为容器的id,通过docker ps -a的第一列可以查看到。

完成后再次运行docker ps,可以看到STATUS状态为UP About……,如下所示,即为启动运行中。

(py3) [root@localhost ~]# docker ps
CONTAINER ID  IMAGE                                                   COMMAND          CREATED      STATUS                 PORTS                                             NAMES
9107b7603bf2  dockerhub.azk8s.cn/wojiushixiaobai/jms_guacamole:1.5.6  ./entrypoint.sh  12 days ago  Up About a minute ago  127.0.0.1:8081->8080/tcp                          jms_guacamole

(py3) [root@localhost ~]#

jumpserver0221_46

再次查看管理主界面的终端列表,“在线”一列中已为在线状态,说明koko和guacamole终端注册成功,运行正常。

jumpserver0221_47

最后,测试用户端运维管理是否正常,使用user01用户登陆,管理jumpserver和网管两台服务器,都可以连接和管理,如下:

jumpserver0221_48

jumpserver0221_49

历史会话记录也正常,能够回放

jumpserver0221_50

至此,整个jumpserver服务器重启后的操作全部完成,功能恢复正常。

8、Centos8上试用开源堡垒机Jumpserver 1.5.6(八):创建用户时使用密码链接并发邮件给用户功能

===================================================================

目前Jumpserver开源堡垒机的最新版本为1.5.6,本次将按照官方“CentOS 8 安装文档”来进行配置,具体配置如下(root用户登陆):

1、更新软件库

通过以下命令完成更新:

[root@localhost ~]# yum update –y

jumpserver27

2、关闭防火墙和关闭SELinux

Jumpserver需要开放80(nginx)和2222(SSH登陆端口koko)两个端口,后期远程管理也需要开放相应端口,这里直接将防火墙关闭:

[root@localhost ~]# firewall-cmd –state
running
[root@localhost ~]#

关闭firewall,并禁止防火墙开机启动,命令如下:

[root@localhost ~]# systemctl stop firewalld.service
[root@localhost ~]# systemctl disable firewalld.service

接着将SELinux关闭,运行如下命令编辑SELINUX配置文件:

[root@localhost ~]# vi /etc/selinux/config

并将SELINUX=enforcing改成SELINUX=disable,如下:

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing – SELinux security policy is enforced.
#     permissive – SELinux prints warnings instead of enforcing.
#     disabled – No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these three values:
#     targeted – Targeted processes are protected,
#     minimum – Modification of targeted policy. Only selected processes are protected.
#     mls – Multi Level Security protection.
SELINUXTYPE=targeted

jumpserver29

修改完成后,重启机器,重启后运行getenforce命令查看已经关闭SELinux。

3、安装依赖包

安装wget、gcc等依赖包:

[root@localhost ~]# yum -y install wget gcc epel-release git

jumpserver30

4、安装Redis

Jumpserver使用Redis做cache和celery broke,,安装redis,设置为开机启动模式,并启动程序,操作如下:

[root@localhost ~]# yum -y install redis
[root@localhost ~]# systemctl enable redis
Created symlink /etc/systemd/system/multi-user.target.wants/redis.service 鈫/usr/lib/systemd/system/redis.service.
[root@localhost ~]# systemctl start redis
[root@localhost ~]#

jumpserver31

5、安装并配置MySQL数据库

开始安装mysql,开源也叫mariadb,操作如下:

[root@localhost ~]# systemctl enable mariadb
[root@localhost ~]# systemctl enable mariadb
Created symlink /etc/systemd/system/mysql.service 鈫/usr/lib/systemd/system/mariadb.service.
Created symlink /etc/systemd/system/mysqld.service 鈫/usr/lib/systemd/system/mariadb.service.
Created symlink /etc/systemd/system/multi-user.target.wants/mariadb.service 鈫/usr/lib/systemd/system/mariadb.service.
[root@localhost ~]#
[root@localhost ~]# systemctl start mariadb
[root@localhost ~]#

接着开始创建数据库,并将数据库授权,操作如下:

生成随机数据库密码:

[root@localhost ~]# DB_PASSWORD=`cat /dev/urandom | tr -dc A-Za-z0-9 | head -c 24`
[root@localhost ~]#
[root@localhost ~]# echo -e “\033[31m 你的数据库密码是 $DB_PASSWORD \033[0m”
  你的数据库密码是 vqMlQ8FhEkhXVCZHGgRatXIp
[root@localhost ~]#
[root@localhost ~]#

jumpserver32

创建jumpserver数据库,如下:

[root@localhost ~]# mysql -uroot -e “create database jumpserver default charset ‘utf8’; grant all on jumpserver.* to ‘jumpserver’@’127.0.0.1’ identified by ‘$DB_PASSWORD’; flush privileges;”
[root@localhost ~]#

到此,数据库创建完成。

6、安装Nginx

由于jumpserver整个软件安装了多个组件,除了jumpserver主站点外,还有koko、guacamole等,通过Nginx来整合各个组件,操作如下:

创建repo文件:

[root@localhost ~]# vi /etc/yum.repos.d/nginx.repo

输入如下内容:

[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

开始安装nginx,并设置为开机自启动:

[root@localhost ~]# yum -y install nginx
[root@localhost ~]# systemctl enable nginx
Created symlink /etc/systemd/system/multi-user.target.wants/nginx.service 鈫/usr/lib/systemd/system/nginx.service.
[root@localhost ~]#

7、安装Python3.6

开始安装:

[root@localhost ~]# yum -y install python36 python36-devel

jumpserver33

配置并进入Python3虚拟环境,首先定义一个虚拟环境名称,本例为py3,如下:

[root@localhost opt]# cd /opt
[root@localhost opt]# python3.6 -m venv py3
[root@localhost opt]#

jumpserver34

接着进入py3虚拟环境,看到py3开头的提示符号代表成功进入,以后运行jumpserver都要先进入py3环境。

[root@localhost opt]# source /opt/py3/bin/activate
(py3) [root@localhost opt]#
(py3) [root@localhost opt]#

jumpserver35

注意:以下开始的步骤都需要在py3环境中执行。

8、安装Jumpserver

下载jumpserver,完成后/opt目录下会产生一个jumpserver的文件夹:

(py3) [root@localhost opt]# git clone –depth=1 https://github.com/jumpserver/jumpserver.git

jumpserver40

安装依据包:

[root@localhost opt]# yum -y install gcc krb5-devel libtiff-devel libjpeg-devel libzip-devel freetype-devel libwebp-devel tcl-devel tk-devel sshpass openldap-devel mariadb-devel libffi-devel openssh-clients telnet openldap-clients

接着安装Python库依赖包:

(py3) [root@localhost opt]#
(py3) [root@localhost opt]# pip install wheel

(py3) [root@localhost opt]# pip install –upgrade pip

编辑依赖包清单requirements.txt文件,暂时去掉python-gssapi==0.6.4:

(py3) [root@localhost opt]# vi /opt/jumpserver/requirements/requirements.txt

jumpserver42

安装依赖包清单里的软件:

(py3) [root@localhost opt]# pip install -r /opt/jumpserver/requirements/requirements.txt -i https://mirrors.aliyun.com/pypi/simple/

jumpserver43

完成后,将requirements.txt中将python-gssapi-0.6.4的注释去掉,再执行一次安装命令,完成安装。

(py3) [root@localhost opt]# pip install -r /opt/jumpserver/requirements/requirements.txt -i https://mirrors.aliyun.com/pypi/simple/

jumpserver44

9、配置和启动jumpserver

修改jumpserver配置文件,复制一份示例文件:

(py3) [root@localhost opt]# cd jumpserver
(py3) [root@localhost jumpserver]# cp config_example.yml config.yml
(py3) [root@localhost jumpserver]#

jumpserver45

然后对配置文件作如下修改:

(py3) [root@localhost jumpserver]#
(py3) [root@localhost jumpserver]# SECRET_KEY=`cat /dev/urandom | tr -dc A-Za-z0-9 | head -c 50`
(py3) [root@localhost jumpserver]# echo “SECRET_KEY=$SECRET_KEY” >> ~/.bashrc
(py3) [root@localhost jumpserver]# BOOTSTRAP_TOKEN=`cat /dev/urandom | tr -dc A-Za-z0-9 | head -c 16`
(py3) [root@localhost jumpserver]# echo “BOOTSTRAP_TOKEN=$BOOTSTRAP_TOKEN” >> ~/.bashrc
(py3) [root@localhost jumpserver]#
(py3) [root@localhost jumpserver]# sed -i “s/SECRET_KEY:/SECRET_KEY: $SECRET_KEY/g” /opt/jumpserver/config.yml
(py3) [root@localhost jumpserver]# sed -i “s/BOOTSTRAP_TOKEN:/BOOTSTRAP_TOKEN: $BOOTSTRAP_TOKEN/g” /opt/jumpserver/config.yml
(py3) [root@localhost jumpserver]# sed -i “s/# DEBUG: true/DEBUG: false/g” /opt/jumpserver/config.yml
(py3) [root@localhost jumpserver]# sed -i “s/# LOG_LEVEL: DEBUG/LOG_LEVEL: ERROR/g” /opt/jumpserver/config.yml
(py3) [root@localhost jumpserver]# sed -i “s/# SESSION_EXPIRE_AT_BROWSER_CLOSE: false/SESSION_EXPIRE_AT_BROWSER_CLOSE: true/g” /opt/jumpserver/config.yml
(py3) [root@localhost jumpserver]# sed -i “s/DB_PASSWORD: /DB_PASSWORD: $DB_PASSWORD/g” /opt/jumpserver/config.yml
(py3) [root@localhost jumpserver]# echo -e “\033[31m 你的SECRET_KEY是 $SECRET_KEY \033[0m”
  你的SECRET_KEY是 fKk8ZyJlq6UCQZqowD3tOHXoJ86BfEaY6fMVsMfDzY4kTLQLja
(py3) [root@localhost jumpserver]# echo -e “\033[31m 你的BOOTSTRAP_TOKEN是 $BOOTSTRAP_TOKEN \033[0m”
  你的BOOTSTRAP_TOKEN是 H4x1afiqgY3MXCiD
(py3) [root@localhost jumpserver]#

修改完成后,检查下配置,特别是以下行中DB_PASSWORD中是否有密码,正常是有刚才随机的密码:

DB_HOST: 127.0.0.1
DB_PORT: 3306
DB_USER: jumpserver
DB_PASSWORD: vqMlQ8FhEkhXVCZHGgRatXIp
DB_NAME: jumpserver

最后启动jumpserver,通过./jms start –d命令,如下:

(py3) [root@localhost /]# cd /opt/jumpserver/
(py3) [root@localhost jumpserver]#
(py3) [root@localhost jumpserver]# ./jms start -d

如上,完成了jumpserver的启动。

10、部署koko和guacamole

koko和guacamole用于远程管理LINUX或WINDOWS主机时使用的连接组件,有本地安装和docker两种方式,本次和官网文档相同,使用docker,不过不使用docker软件,使用podman,原理基本相同。

首先安装podman:

(py3) [root@localhost jumpserver]# yum install -y podman-docker

jumpserver47

修改别名,这样可以使用docker开头的命令,符合使用习惯:

(py3) [root@localhost jumpserver]# alias docker=podman
(py3) [root@localhost jumpserver]# echo “alias docker=podman” >> ~/.bashrc

配置podman镜像源,编辑/etc/containers/registries.conf文件,将

registries = [‘registry.access.redhat.com’, ‘registry.fedoraproject.org’, ‘registry.centos.org’, ‘docker.io’]

修改为

registries = [‘dockerhub.azk8s.cn’, ‘docker.mirrors.ustc.edu.cn’, ‘docker.io’]

获取服务器IP地址并输入koko和guacamole镜像:

(py3) [root@localhost jumpserver]# Server_IP=`ip addr | grep ‘state UP’ -A2 | grep inet | egrep -v ‘(127.0.0.1|inet6|docker)’ | awk ‘{print $2}’ | tr -d “addr:” | head -n 1 | cut -d / -f1`
(py3) [root@localhost jumpserver]# echo -e “\033[31m 你的服务器IP是 $Server_IP \033[0m”
  你的服务器IP是 192.168.10.216
(py3) [root@localhost jumpserver]#
(py3) [root@localhost jumpserver]#
(py3) [root@localhost jumpserver]# docker run –name jms_koko -d -p 2222:2222 -p 127.0.0.1:5000:5000 -e CORE_HOST=http://$Server_IP:8080 -e BOOTSTRAP_TOKEN=$BOOTSTRAP_TOKEN wojiushixiaobai/jms_koko:1.5.6

jumpserver48

11、安装WEB Terminal

(py3) [root@localhost jumpserver]# cd /opt
(py3) [root@localhost opt]# wget https://github.com/jumpserver/luna/releases/download/1.5.6/luna.tar.gz
(py3) [root@localhost opt]#
(py3) [root@localhost opt]# tar xf luna.tar.gz
(py3) [root@localhost opt]#
(py3) [root@localhost opt]# ls
jumpserver  luna  luna.tar.gz  py3
(py3) [root@localhost opt]#
(py3) [root@localhost opt]# chown -R root:root luna
(py3) [root@localhost opt]#

jumpserver49

12、配置并运行Nginx

通过NGINX来整合之前安装的各种组件,确保统一访问路径,操作如下:

(py3) [root@localhost opt]# rm -rf /etc/nginx/conf.d/default.conf
(py3) [root@localhost opt]#
(py3) [root@localhost opt]# vi /etc/nginx/conf.d/jumpserver.conf

添加如下内容:

server {
     listen 80;
     # server_name _;

    client_max_body_size 100m;  # 录像及文件上传大小限制

    location /luna/ {
         try_files $uri / /index.html;
         alias /opt/luna/;  # luna 路径, 如果修改安装目录, 此处需要修改
     }

    location /media/ {
         add_header Content-Encoding gzip;
         root /opt/jumpserver/data/;  # 录像位置, 如果修改安装目录, 此处需要修改
     }

    location /static/ {
         root /opt/jumpserver/data/;  # 静态资源, 如果修改安装目录, 此处需要修改
     }

    location /koko/ {
         proxy_pass       http://localhost:5000;
         proxy_buffering off;
         proxy_http_version 1.1;
         proxy_set_header Upgrade $http_upgrade;
         proxy_set_header Connection “upgrade”;
         proxy_set_header X-Real-IP $remote_addr;
         proxy_set_header Host $host;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         access_log off;
     }

    location /guacamole/ {
         proxy_pass       http://localhost:8081/;
         proxy_buffering off;
         proxy_http_version 1.1;
         proxy_set_header Upgrade $http_upgrade;
         proxy_set_header Connection $http_connection;
         proxy_set_header X-Real-IP $remote_addr;
         proxy_set_header Host $host;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         access_log off;
     }

    location /ws/ {
         proxy_pass http://localhost:8070;
         proxy_http_version 1.1;
         proxy_buffering off;
         proxy_set_header Upgrade $http_upgrade;
         proxy_set_header Connection “upgrade”;
         proxy_set_header X-Real-IP $remote_addr;
         proxy_set_header Host $host;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         access_log off;
     }

    location / {
         proxy_pass http://localhost:8080;
         proxy_set_header X-Real-IP $remote_addr;
         proxy_set_header Host $host;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         access_log off;
     }
}

完成后开始运行Nginx,先运行nginx -t查看,确保配置没有问题:

(py3) [root@localhost opt]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
(py3) [root@localhost opt]#
(py3) [root@localhost opt]#

jumpserver50

没问题后运行nginx:

(py3) [root@localhost opt]# systemctl start nginx
(py3) [root@localhost opt]#
(py3) [root@localhost opt]# systemctl status nginx
鈼[0m nginx.service – nginx – high performance web server

(py3) [root@localhost opt]#

jumpserver51

完成后,打开浏览器,输入http://192.168.10.216,出现登陆界面,用户名密码默认都为admin,如下图,

jumpserver53

jumpserver54

进入后,打开“会话管理”->“终端管理”,由于装了KOKO和guacamole,故正常情况下会有两个终端设备,如下,若没有出现,则koko和guacamole可能安装没成功,如下图所示。

jumpserver55

至此,jumpserver在centos8上的部署已完成 ,下步就需要添加用户和设备资源,使jumpserver可以远程管理相应设备或系统。

参考文章:
1、CentOS 8 安装文档
https://jumpserver.readthedocs.io/zh/master/setup_by_centos8.html

4、Jumpserver单机快速部署前的准备工作及部署流程

Zabbix 4.0.2试用(七):在Linux主机中安装zabbix agent并添加该主机(yum源安装)

之前介绍的是下载源安装包,编译安装的方式来安装agent,本次将采用yum源方式安装,前提是主机需要与互联网相通,操作如下:

1、关闭防火墙和SELINUX

使用root用户登陆系统:

首先查看防火墙状态

[root@zabbix ~]# firewall-cmd –state
running
[root@zabbix ~]#

关闭firewall,并禁止防火墙开机启动,命令如下:

[root@zabbix ~]# systemctl stop firewalld.service
[root@zabbix ~]# systemctl disable firewalld.service

再次查看,防火墙已不在运行:

[root@zabbix ~]# firewall-cmd –state

安装之前还需将SELINUX关闭,运行如下命令编辑SELINUX配置文件:

[root@zabbix ~]# vi /etc/selinux/config

并将SELINUX=enforcing改成SELINUX=disable,如下:

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing – SELinux security policy is enforced.
#     permissive – SELinux prints warnings instead of enforcing.
#     disabled – No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
#     targeted – Targeted processes are protected,
#     minimum – Modification of targeted policy. Only selected processes are protected.
#     mls – Multi Level Security protection.
SELINUXTYPE=targeted

修改完成后,重启机器,运行如下命令查看是否 SELINUX已关闭:

[root@zabbix ~]# getenforce

退回disable即为已关闭。

2、安装Zabbix Agent

首先需添加对应的yum repository:

进入zabbix官网文档,选择产品手册->安装->从二进制包安装->1 Red Hat Enterprise,

zabbixinstallx21

zabbixagentyum01

开始安装agent:

[root@localhost ~]# yum install zabbix-agent

[root@localhost ~]#

3、配置Zabbix Agent

完成安装后,开始配置zabbix_agentd.conf配置文件:

[root@localhost ~]# vi /etc/zabbix/zabbix_agentd.conf

主要完成以下几项的修改:

EnableRemoteCommands=1       //来至zabbix服务器的远程命令是否允许被执行
Server=192.168.10.208             //zabbix server地址,用于被动模式,数据获取
ServerActive=192.168.10.208    //主动发送的zabbix server地址,用于主动模式,数据提交
Hostname=localhost                  //和创建主机时的hostname一致
UnsafeUserParameters=1           //启用自定义key,zabbix监控mysql、tomcat等数据时需要自定义key

完成后保存退出。

4、启动Zabbix Agent

配置文件修改后,开始启动服务:

启动服务:

[root@localhost ~]# systemctl start zabbix-agent.service

添加开机启动功能:

[root@localhost ~]# systemctl enable zabbix-agent.service
Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-agent.service to /usr/lib/systemd/system/zabbix-agent.service.

查看agent服务是否已启动:

[root@localhost ~]# ps -ef | grep zabbix
zabbix    2842     1  0 06:37 ?        00:00:00 /usr/sbin/zabbix_agentd -c /etc/zabbix/zabbix_agentd.conf
zabbix    2843  2842  0 06:37 ?        00:00:00 /usr/sbin/zabbix_agentd: collector [idle 1 sec]

[root@localhost ~]# ss -tnl | grep 10050
LISTEN     0      128          *:10050                    *:*                 
LISTEN     0      128         :::10050                   :::*                

如上,已发现agentd进程运行,并且10050端口已启动。

6、将主机添加至zabbix server平台

打开zabbix server主界面,选择“配置‘->”主机“,点击右上角的”创建“按扭,创建一台主机,如下图

agentinstall06

输入主机名称,群组选择系统默认的Server hardware,agent代理接口IP设置刚才安装agent的主机192.168.10.209,端口默认10050,如下图:

agentinstall07

再选择”模板“选项栏,链接指示器里选择”Template OS Linux“,点击添加,最后点击蓝底添加按扭,完成添加。

agentinstall08

完成后可以看到列表中已经有刚才不回的主机,过几分钟后,可用性一栏中的ZBX变绿即表示监控正常。

邻居状态在Exstart与Exchange中来回切换。

参考此文解决:

由于两路由器间的MTU不匹配引起的,调整相应接品的MTU或者设置为忽略检测MTU,该设置不支持交换口。

在接口上启用如下命令来忽略MTU的检测:

cisco-master#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
cisco-master(config)#interface fastEthernet 0/0
cisco-master(config-if)#ip ospf mtu-ignore

联想天工iSpirit 2948G交换机端口和MAC绑定及端口带宽限制

前段时间接触了联想天工交换机,核心为联想天工iSpirit8800,楼层都为天工iSpirit 2948G,在楼层上做了两个限制,一是将端口与用户的网卡MAC绑定,只有绑定的网卡数据包才能出去,二是限制了每个端口的带宽(防止P2P下载),配置如下:

1、端口与MAC地址绑定

MAC与端口绑定

shiyan#conf t
//进入配置模式
shiyan_config#interface fastEthernet 0/11
//进入交换机11端口配置模式
shiyan_config_f0/11#switchport port-security mode static accept
//打开安全端口的模式
shiyan_config_f0/11#switchport port-security static mac-address 0001.4A22.E728
//设置安全端口的安全MAC
shiyan_config_f0/11#switchport port-security static mac-address 0001.4DFF.EEFD
//设置安全端口的安全MAC
shiyan_config_f0/11#exit
shiyan_config#exit
shiyan#wr
//写入配置
Saving current configuration…
OK!

去除MAC与端口绑定

shiyan#conf t
//进入配置模式
shiyan_config#interface fastEthernet 0/11
//进入交换机11端口配置模式
shiyan_config_f0/11#no switchport port-security static mac-address 0001.4A22.E728
//设置去除安全端口的安全MAC地址
shiyan_config_f0/11#no switchport port-security static mac-address
//设置去除所有安全端口的安全MAC
shiyan_config_f0/11#exit
shiyan_config#exit
shiyan#wr
//写入配置
Saving current configuration…
OK!

只打开端口的安全端口功能(此端口不能上网)

shiyan#conf t
//进入配置模式
shiyan_config#interface fastEthernet 0/11
//进入交换机11端口配置模式
shiyan_config_f0/11#switchport port-security mode static accept
//打开11口的安全端口功能
shiyan_config_f0/11#exit
shiyan_config#exit
shiyan#wr
//写入配置
Saving current configuration…
OK!

打开多端口的安全端口功能(此些端口不能上网)

shiyan#conf t
//进入配置模式
shiyan_config#interface range fastEthernet 0/11 – 20
//进入交换机11-20端口配置模式
shiyan_config_f0/11#switchport port-security mode static accept
//打开11口的安全端口功能
shiyan_config_f0/11#exit
shiyan_config#exit
shiyan#wr
//写入配置
Saving current configuration…
OK!

2、端口带宽限制

通过设置端口的rate-limit参数来限制端口带宽,共有1-32个单位可以设置,每个单位速度为3.3Mbps(约330KB/S)下载速度。端口有进和出的限制,都限制为1,这样上行和下行的带宽共为2个单位,约660KB/S。操作如下:

shiyan#conf t
shiyan_config#interface fastEthernet 0/42
shiyan_config_f0/42#switchport rate-limit 1 ingress
shiyan_config_f0/42#switchport rate-limit 1 egress
//limit单位1-32,每个单位速度为3.3Mbps
shiyan_config_f0/42#exit
shiyan_config#exit
shiyan#wr
