Zabbix 4.0.2试用(三):安装Zabbix 4.0.2

完成上一步的CentOS7的安装后,开始安装Zabbix,具体步骤如下:

使用root用户登陆系统:

1、关闭防火墙

首先查看防火墙状态

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

zabbixinstall

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

zabbixinstall

2、关闭SELINUX

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

zabbixinstallx03

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,如下图。

zabbixinstallx04

3、安装LAMP环境

Zabbix前端为PHP,后端准备使用的数据库为MariaDB(与MYSQL兼容,mysql创始化带领团队创建),目前集合的环境有LAMP和LNMP,只是WEB应用使用Apache或Nginx的区别,本次准备采用LAMP来运行Zabbix,因为本机与互联网相通,故准备采用yum的方式来安装。

首先升级相关yum源中的软件至最新版,使用如下命令:

[root@zabbix ~]# yum -y update

开始对程序进行升级,如下图:

zabbixinstallx05

zabbixinstallx06

如上图,完成了yum源升级后,开始安装LAMP,运行如下命令:

[root@zabbix ~]# yum install -y httpd mariadb-server mariadb php php-mysql php-gd libjpeg* php-ldap php-odbc php-pear php-xml php-xmlrpc php-mhash

开始安装,如下图:

zabbixinstallx07

完成安装后,使用如下命令查看重要是否已安装:

[root@zabbix ~]# rpm -qa httpd php mariadb
httpd-2.4.6-88.el7.centos.x86_64
mariadb-5.5.60-1.el7_5.x86_64
php-5.4.16-46.el7.x86_64
[root@zabbix ~]#

如上,显示已安装了http、php和数据库mariadb。

4、配置LAMP环境

完成LAMP环境安装后,开始配置Apache和PHP,通过如下命令打开httpd.conf配置文件,修改ServerName和DirectoryIndex,将监听IP及端口修改为本机的IP及80端口,DirectoryIndex中加入index.php文件:

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

由于本机的IP为10.208,则ServerName修改成:

ServerName 192.168.10.208:80

zabbixinstallx08

Zabbix默认页面为index.php,添加index.php进DirectoryIndex,如下:

<IfModule dir_module>
    DirectoryIndex index.html index.php
< /IfModule>

zabbixinstallx09

完成以上修改为保存退出。

再修改php.ini配置文件,设置时区为PRC,由于运维管理系统是记录设备运维日志等,需要查看设备出现问题时的时间,对时间的准确性有要求,故需修改:

[root@zabbix ~]# vi /etc/php.ini

使用/timezone搜索需要修改的位置,并修改为:

date.timezone = PRC

zabbixinstallx10

完成后保存退出。

5、启动LAMP环境

开始启动httpd和mariadb:

[root@zabbix ~]# systemctl start httpd
[root@zabbix ~]# systemctl start mariadb

设置开机启动服务:

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

查看服务是否启动:

[root@zabbix ~]# ss -naplt | grep httpd
LISTEN     0      128         :::80                      :::*                   users:((“httpd”,pid=26988,fd=4),(“httpd”,pid=26987,fd=4),(“httpd”,pid=26986,fd=4),(“httpd”,pid=26985,fd=4),(“httpd”,pid=26984,fd=4),(“httpd”,pid=26980,fd=4))
[root@zabbix ~]# ss -naplt | grep mysqld
LISTEN     0      50           *:3306                     *:*                   users:((“mysqld”,pid=27272,fd=13))
[root@zabbix ~]#

查看httpd和mysqld已经启动,80和3306端口也已启动,如下图:

zabbixinstallx11

接着再测试php是否正常,新建一个PHP测试页:

[root@zabbix ~]# vi /var/www/html/index.php

输入:

<?php
phpinfo();
?>

zabbixinstallx12

保存退出,然后打开浏览器,输入http://192.168.10.208,显示PHP即为正常。

zabbixinstallx13

6、配置MariaDB数据库

设置数据库密码为zabbixroot:

[root@zabbix ~]# mysqladmin -u root password zabbixroot

验证密码是否正常:

[root@zabbix ~]# mysql -u root -p
Enter password:
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 3
Server version: 5.5.60-MariaDB MariaDB Server

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the current input statement.

MariaDB [(none)]>

zabbixinstallx14

开始创建数据库,

MariaDB [(none)]> CREATE DATABASE zabbix character set utf8 collate utf8_bin;
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> GRANT all ON zabbix.* TO ‘zabbix’@’zabbix’ IDENTIFIED BY ‘zabbix123’;
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> quit
Bye
[root@zabbix ~]#

zabbixinstallx15

完成创建后,测试数据库是否能够连接,运行是否正常,将刚创建的php测试页的内容修改为:

<?php
$link=mysql_connect(‘192.168.10.208′,’zabbix’,’zabbix123′);
if($link) echo “<h1>Datebase Connect Success~~~~~</h1>”;
  else echo “Fail!!”;
mysql_close();
?>

设置本机的IP地址,并设置刚才创建的用户名和密码:

zabbixinstallx17

设置后保存退出,然后在浏览器中输入http://192.168.10.208,正常应该显示Datebase Connect Success~~~~~:

zabbixinstallx18

7、安装Zabbix 4.0.2

完成以上的设置后,即可以开始安装Zabbix,继续采用yum方式安装,首先安装相关依赖包:

[root@zabbix ~]# yum -y install net-snmp net-snmp-devel curl curl-devel libxml2 libxml2-devel libevent-devel.x86_64 javacc.noarch  javacc-javadoc.noarch javacc-maven-plugin.noarch javacc*

yum会自动下载安装包并完成安装,

zabbixinstallx19

再安装PHP组件包,用于支持zabbix:

[root@zabbix ~]# yum install php-bcmath php-mbstring –y

开始安装:

zabbixinstallx20

完成后开始安装Zabbix,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

zabbix共有3个核心组件,server、proxy及web,本次只安装基于mysql数据库的server和web:

zabbixinstallx22

8、导入数据并配置zabbix数据库

完成zabbix的安装后,之前在mariadb中创建的zabbix数据库中是没有数据的,需要将zabbix提供的模板表结构等数据导入zabbix数据库中,进行如下操作:

[root@zabbix ~]# zcat /usr/share/doc/zabbix-server-mysql-4.0.2/create.sql.gz | mysql -uzabbix -p -h 192.168.10.208 zabbix
Enter password:
[root@zabbix ~]#

zabbixinstallx23

输入之前zabbix用户的用户名,这里为zabbix123,输入后自动开始导入,等待10秒左右,未出现错误,则表示导入成功。

完成后开始配置zabbix server的配置文件,使配置文件中引用刚才创建的数据库,编辑/etc/zabbix/zabbix_server.conf文件:

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

主要设置以下几项:

DBHost=zabbix
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix123

zabbixinstallx26

9、修改zabbix配置文件时区及PHP参数设置

由于时间的重要性,需要将zabbix的时区也改成本地时区:

[root@zabbix ~]# vi /etc/httpd/conf.d/zabbix.conf

将php_value date.timezone 开关的#号去除,然后值修改为Asia/Shanghai,如下。

zabbixinstallx25

完成后保存退出即可。

10、启动zabbix服务并完成安装

以上操作完成后,可以启动zabbix server:

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

完成后重启服务器,然后进入/var/log/zabbix,查看zabbix_server.log日志文件,未发现相关错误:

开始完成安装,浏览器打开http://192.168.10.208/zabbix,主界面已显示,点击Next Step:

zabbixinstallx27

zabbixinstallx28

填入相应信息,端口为3306,用户名及密码为之前创建的信息,如下图

zabbixinstallx29

输入host,这里为zabbix,端口默认,名称自定义

zabbixinstallx30

最后确认信息是否正常:

zabbixinstallx31

zabbixinstallx32

完成后,显示登陆界面,输入默认信息:用户名Admin,密码zabbix,进入主界面。

zabbixinstallx33

zabbixinstallx34

至此,zabbix的安装完成,后期将是相关配置的工作。

Zabbix 4.0.2试用(二):安装操作系统CentOS 7

准备Zabbix安装在Linux平台下,使用CentOS 7,具体安装步骤如下:

首先在虚拟化平台上建立一个虚机:

DVD驱动器中选择“数据存 ISO文件”,选择本ESXI主机上的CENTOS7 ISO镜像文件,并在“连接”上打钩,如下图所示:

完成新建后,打开虚拟机电源,进行CentOS7安装界面,

语言选择英文

开始设置一些安装参数,如下图

首先设置“DATE & TIME”设置,将时区设置成上海,如下图

在设置“SOFTWARE SELECTION”,设置为Server with GUI,如下图

在对“INSTALLATION DESTINATION”进行设置,默认的分区不太适合ZABBIX的运行,需要手工更改下,如下图,选择100G磁盘,再选择“I will configure partitioning”,如下图

默认/home分区空间分配很大,需要手工调小,将根/分区空间调大,因为安装ZABBIX时,软件的运行日志等都在/var目录下,需要更多的空间支持,如下图

最后,对“NETWORK & HOST NAME”进行设置,将host name设置为zabbix,将IP地址设置为你自己环境中的IP,本次为192.168.10.208/24,网关10.253,DNS:221.228.255.1,如下图所示:

完成设置后,下一步,开始安装,同时完成root密码的设置,如下图

完成安装后,重启机器,并完成最后的设置工作,最后点击FINISH CONFIGURATION按扭,重启完成安装。如下图

进入系统后,测试下到网关和互联网是否正常,安装ZABBIX时会用到互联网。
