Zabbix 4.4试用(五):通过SNMP监控CentOS7服务器

通过SNMP来监控LINUX服务器,首先在CENTOS服务器上安装SNMP,如下:

[root@localhost ~]# yum -y install net-snmp net-snmp-utils
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
  * base: mirrors.cn99.com
  * extras: mirrors.nju.edu.cn
  * updates: mirrors.nju.edu.cn
base

[root@localhost ~]# rpm -qa | grep snmp
net-snmp-libs-5.7.2-43.el7_7.3.x86_64
net-snmp-5.7.2-43.el7_7.3.x86_64
net-snmp-utils-5.7.2-43.el7_7.3.x86_64
net-snmp-agent-libs-5.7.2-43.el7_7.3.x86_64

zabbix4.4config_20

zabbix4.4config_21

通过snmpd -v查看SNMP版本:

[root@localhost ~]# snmpd -v

NET-SNMP version:  5.7.2
Web:               http://www.net-snmp.org/
Email:             net-snmp-coders@lists.sourceforge.net

[root@localhost ~]#

zabbix4.4config_22

开始更改团体名,更改为lsywsnmp123:

[root@localhost ~]# vi /etc/snmp/snmpd.conf

com2sec notConfigUser  default       public

更改为

com2sec notConfigUser  default       lsywsnmp123

重启SNMP服务,并设置为开机启动,如下:

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

zabbix4.4config_23

接着开始ZABBIX端的设置,添加这台CENTOS服务器:

zabbix4.4config_24

模块设置:

zabbix4.4config_27

设置宏中的团体名

zabbix4.4config_26

完成后,清单中已有服务器,SNMP监控也显示绿色,正常。

zabbix4.4config_28

Zabbix 4.4试用(四):通过SNMP监控Windows 2008R2

ZABBIX支持通过zabbix agent或SNMP来添加和监控WINDOWS服务器,本次将以WINDOWS 2008R2为例 ,通过SNMP来实现WINDOWS服务器的监控,操作如下:

首先在WINDOWS服务器上启用SNMP,打开服务器管理器,在【功能】选项栏上,选择【添加功能】,如下图

zabbix4.4config_12

选择SNMP服务,如下图

zabbix4.4config_13

完成后,进入【服务】界面,在SNMP Service右键,选择【属性】,如下图

zabbix4.4config_14

在安全选项中,设置相关参数,在社区名称中设置lsywsnmp123,在接受主机一栏中选择ZABBIX SERVER的IP 192.168.10.217,如下图所示,完成后点击确定。

zabbix4.4config_15

接着进入ZABBIX配置界面开始添加这台服务器,方法和添加华交换机一样,选择添加主机按扭,如下图,输入主机名称、可见的名称、群组和SNMP接口信息等

zabbix4.4config_16

在链接的模板中选择Template OS Windows SNMPv2,如下图

zabbix4.4config_17

在宏选项栏中,宏中输入{$SNMP_COMMUNITY},值中输入lsywsnmp123,如下图

zabbix4.4config_18

完成后,清单中就能看到添加的备份服务器,且SNMP监控为绿色,监控正常。

zabbix4.4config_19

Zabbix 4.4试用(三):通过SNMP监控华为交换机S5700

zabbix支持通过SNMP或ZABBIX AGENT采集设备信息,交换机自带SNMP,且不能安装ZABBIX AGENT组件,故交换机一般通过SNMP来管理,首先配置交换机,启用SNMP,操作如下:

[Lan-center-s5700]snmp-agent
[Lan-center-s5700]snmp-agent community read cipher lsywsnmp123
[Lan-center-s5700]snmp-agent sys-info version all

zabbix4.4config_06

启用SNMP后,在zabbix中添加此交换机,开始监控,操作如下:

进入【配置】-【主机】配置界面,点击右上角的【创建主机】按扭,如下图所示

zabbix4.4config_07

主机名称中输入全英文的名称,可见的名称中输入页面最终显示的中文名称,如下图所示,群组中选择网络群组,并移除agent代理程序的接口,SNMP接口点【添加】,并输入交换机的管理地址192.168.10.253,端口使用161默认不变。

zabbix4.4config_08

再切换至模板选项栏,在Link new templates中选择【Template Net Huawei VRP SNMPv3】,如下图所示

zabbix4.4config_09

切换至宏选项栏,在宏一栏中输入{$SNMP_COMMUNITY},在值一栏中输入刚才交换机设置的SNMP密码lsywsnmp123,如下图所示,完成后,点击【更新】按扭完成添加。

zabbix4.4config_10

过一估时间,列表中就有华为S5700核心交换机清单,监控项、触发器、图形等都有内容,如下图。

zabbix4.4config_11

至此,交换机添加完成。

Zabbix 4.4试用(二):将图形界面中的乱码修复为中文显示

默认zabbix在图形显示中中文显示为乱码,需要修复才能正常显示,如下图红框所示:

zabbix4.4config_01

操作如下:

首先将WINDOWS FONTS文件夹中的黑体字复制至本机硬盘

zabbix4.4config_02

然后在服务器上操作zabbix-web-nginx-mysql容器,通过docker ps查看zabbix-web-nginx-mysql容器的ID,如下图,这里为48a2c96acc9c

zabbix4.4config_03

通过docker exec进入进入zabbix-web-nginx-mysql容器进行操作,首先查询需要修改的DejaVuSans.ttf和defines.inc.php两个文件的位置,操作如下:

[root@localhost zabbix]# docker exec -it 48a2c96acc9c bash
bash-5.0# find / -name DejaVuSans.ttf
/usr/share/zabbix/assets/fonts/DejaVuSans.ttf
bash-5.0#
bash-5.0# find / -name defines.inc.php
/usr/share/zabbix/include/defines.inc.php
bash-5.0#

然后将刚才本地电脑上的黑体字体文件simhei.ttf复制到/usr/share/zabbix/assets/fonts/目录下,然后通过vi修改defines.inc.php文件,将红框位置中原DejaVuSans修改为simhei,如下图,完成后保存退出。

zabbix4.4config_04

再次刷新图形,已能显示中文,如下图所示。至此修改完成。

zabbix4.4config_05

Zabbix 4.4试用(一):在Centos7上通过Docker方式安装Zabbix 4.4

之前采用一步步安装方式完成了zabbix4.0.2的安装,最近有4.4新版本,且想通过Docker方式安装,操作步骤简洁好多,准备一试。

首先在VMware vSphere平台上完成Centos7.5.1804虚拟机的安装,配置IP地址。然后完成如下步骤的安装:

1、关闭并禁用防火墙

[root@localhost etc]# firewall-cmd –state
running
[root@localhost etc]#
[root@localhost etc]# systemctl stop firewalld.service
[root@localhost etc]#
[root@localhost etc]#
[root@localhost etc]# systemctl disable firewalld.service
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@localhost etc]#
[root@localhost etc]#
[root@localhost etc]# firewall-cmd –state
not running
[root@localhost etc]#

zabbixdocker4.4_01

2、关闭SELINUX

将配置文件/etc/selinux/config的SELINUX设置为disabled,操作如下:

[root@localhost etc]# sed -i ‘s#SELINUX=enforcing#SELINUX=disabled#g’ /etc/selinux/config
[root@localhost etc]#
[root@localhost etc]#
[root@localhost etc]# grep "SELINUX=disabled" /etc/selinux/config
SELINUX=disabled
[root@localhost etc]#

zabbixdocker4.4_02

配置完成后reboot重启,再使用getenforce命令查看是否关闭SELINUX:

[root@localhost ~]# getenforce
Disabled
[root@localhost ~]#

zabbixdocker4.4_03

3、安装docker

开始安装docker,首先安装docker-ce所需的依赖包:

[root@localhost ~]# yum install -y yum-utils device-mapper-persistent-data lvm2
Loaded plugins: fastestmirror, langpacks
Determining fastest mirrors
  * base: mirrors.163.com
  * extras: mirrors.aliyun.com
  * updates: mirrors.163.com
base

zabbixdocker4.4_04

设置docker-ce在线存储库,这里设置为阿里云在线存储库,操作如下:

[root@localhost ~]# yum-config-manager –add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
Loaded plugins: fastestmirror, langpacks
adding repo from: http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

repo saved to /etc/yum.repos.d/docker-ce.repo
[root@localhost ~]#
[root@localhost ~]#

zabbixdocker4.4_05

开始安装docker,

[root@localhost ~]# yum clean all
Loaded plugins: fastestmirror, langpacks
Cleaning repos: base docker-ce-stable extras updates
Cleaning up everything
Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos

zabbixdocker4.4_06

启动并开机自启动docker,操作如下:

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

4、安装zabbix

启动一个mysql实例,操作如下:

[root@localhost ~]# docker run –name mysql-server -t -e MYSQL_DATABASE="zabbix" -e MYSQL_USER="zabbix" -e MYSQL_PASSWORD="zabbix" -e MYSQL_ROOT_PASSWORD="zabbix" -d mysql:5.7  –character-set-server=utf8 –collation-server=utf8_bin

完成后启动ZABBIX JAVA GATEWAY实例,操作如下:

[root@localhost ~]# docker run –name zabbix-java-gateway -t –restart unless-stopped -d zabbix/zabbix-java-gateway:latest
Unable to find image ‘zabbix/zabbix-java-gateway:latest’ locally

[root@localhost ~]#

zabbixdocker4.4_09

完成后开始启动zabbix server实例,并关联这个实例到刚才已创建的MYSQL服务器实例,操作如下:

[root@localhost ~]# docker run –name zabbix-server-mysql -t -e DB_SERVER_HOST="mysql-server" -e MYSQL_DATABASE="zabbix" -e MYSQL_USER="zabbix" -e MYSQL_PASSWORD="zabbix" -e MYSQL_ROOT_PASSWORD="zabbix" –link mysql-server:mysql -p 10051:10051 -d zabbix/zabbix-server-mysql:latest

[root@localhost ~]#

zabbixdocker4.4_10

最后启动ZABBIX WEB接口,并将它与MYSQL服务器实例和ZABBIX SERVER实例关联,操作如下:

[root@localhost ~]# docker run –name zabbix-web-nginx-mysql -t -e DB_SERVER_HOST="mysql-server" -e MYSQL_DATABASE="zabbix" -e MYSQL_USER="zabbix" -e MYSQL_PASSWORD="zabbix" -e MYSQL_ROOT_PASSWORD="zabbix" –link mysql-server:mysql –link zabbix-server-mysql:zabbix-server -p 8080:80 -d zabbix/zabbix-web-nginx-mysql:latest
