zabbix4.0的安装与配置

安装zabbix监控首先的先安装LNMP环境，在这里我采用事先准备好的脚本进行安装LNMP环境脚本内容如下：

  1 #!/bin/bash

以上为lnmp环境的搭建，不要准备包，全部在线下载，整个过程最多30分钟，这个只是基本的lnmp环境

如果说要安装zabbix4.0的话还需要满足他的先决条件，在这里我们一步步的来，遇到阻挡了再去安装。

zabbix4.0的先决条件先贴出来

下面开始安装zabbix4.0

软件包下载地址：https://www.zabbix.com/download_sources

解压软件包：

yum install -y net-snmp-devel

1 tar zxf zabbix-4.0.0.tar.gz
2 cd zabbix-4.0.0
3 ./configure --prefix=/usr/local/zabbix --enable-server --enable-agent --with-mysql --enable-ipv6 --with-net-snmp --with-libcurl --with-libxml2

在这里有可能会发生报错：

现象1：

configure: error: Not found mysqlclient library

解决：将编译时的--with-mysql后面跟上数据库的安装路径

1 make && make install

到这里安装成功，下面开始配置各项配置文件

1 vim /usr/local/zabbix/etc/zabbix_server.conf
2 DBHost=localhost #默认注释掉了，直接取消注释即可
3 DBName=zabbix #数据库名字
4 DBUser=zabbix #默认是root，我们授权的用户是zabbix
5 DBPassword=zabbix #密码我们授权的也是zabbix

下面是数据库的导入与授权操作

1.先登录数据库

在这里也许你会不知道数据库该怎么登录，因为你并不知道数据库密码

初始密码获取方法：

1 cat /usr/local/mysql/log/mysql.err | grep password

黄色框里面的就是数据库的初始密码了

登录数据库以后必须更改初密码，否则无法进行建库等操作

更改密码：

1 use mysql;
2 update user set password=password('mysql') where user='root';
3 flush privileges;
4 create database zabbix;
5 grant all on zabbix.* to zabbix@'localhost' identified by 'zabbixmysql';
6 flush privileges;

接下来是导入数据库：

1 cd /usr/src/zabbix-4.0.0
2 mysql -uzabbix -pzabbixmysql zabbix < database/mysql/schema.sql
3 mysql -uzabbix -pzabbixmysql zabbix < database/mysql/images.sql
4 mysql -uzabbix -pzabbixmysql zabbix < database/mysql/data.sql

下面我们可以写一个数据库连通性的测试页面放到nginx的html目录下：

1 vim /usr/local/nginx/html/mysqltest.php

1 <?php
2 $link=mysql_connect('localhost','zabbix','zabbix');
3 if($link) echo "<h1>The database connection was successful!</h1>";
4 else echo "<h1>The database connection was Fail!!</h1>";
5 mysql_close();
6 ?>

浏览器访问nginx的IP后面加上测试文件文件名出先下面内容则代表连接成功：

zabbix4.0的安装与配置-LMLPHP

接下来就是进入zabbix的web界面了，这时候需要把前端文件copy到nginx的HTML目录下

1 mkdir /usr/local/nginx/html/zabbix
2 cd /usr/src/zabbix-4.0.0/frontends/php/
3 cp * /usr/local/nginx/html/zabbix/

进入web界面：http://ip/zabbix/

下面是安装过程遇到的问题

提示不满足zabbix的先决条件

根据提示去更改php.ini的相关数值，参考上面的先决条件

在这个过程可能会涉及到php模块的安装，可以参考php扩展模块的安装方法安装就能完成
