CentOS7.3 64位，搭建Zabbix3.4

一、系统环境

[root@ecs-5c78-0001 ~]# cat /etc/redhat-release
 CentOS Linux release 7.3.1611 (Core)

为了方便测试，停止并且开机不启动防火墙，生产环境根据需要进行调整

[root@ecs-5c78-0001 ~]# systemctl stop firewalld.service
[root@ecs-5c78-0001 ~]# systemctl disable firewalld.service

关闭selinux

[root@ecs-5c78-0001 ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
[root@ecs-5c78-0001 ~]# grep SELINUX=disabled /etc/selinux/config
SELINUX=disabled
[root@ecs-5c78-0001 ~]# setenforce 0
setenforce: SELinux is disabled

二、数据库的安装和配置

1、安装之前检查系统中是否存在使用rpm安装的MySQL或者MariaDB

[root@ecs-5c78-0001 ~]# rpm -qa | grep mysql
[root@ecs-5c78-0001 ~]# rpm -qa | grep mariadb
mariadb-libs-5.5.52-1.el7.x86_64

2、如果需要卸载，执行命令：rpm -e 软件名，执行失败的时候可以使用：rpm -e --nodeps 软件名强制卸载，卸载之后再使用
rpm -qa | grep mysql 或者rpm -qa | grep mariadb查看结果。

[root@ecs-5c78-0001 ~]# rpm -e mariadb-libs-5.5.52-1.el7.x86_64
error: Failed dependencies:
	libmysqlclient.so.18()(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64
	libmysqlclient.so.18(libmysqlclient_18)(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64
[root@ecs-5c78-0001 ~]# rpm -e --nodeps mariadb-libs-5.5.52-1.el7.x86_64

安装mariadb

[root@ecs-5c78-0001 ~]# yum install mariadb-server mariadb –y

启动数据库并设置为开机启动

[root@ecs-5c78-0001 ~]# systemctl start mariadb
[root@ecs-5c78-0001 ~]# systemctl enable mariadb
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

#数据库其他操作命令

[root@ecs-5c78-0001 ~]# systemctl restart mariadb	#重启
[root@ecs-5c78-0001 ~]# systemctl stop mariadb		#停止

三、Zabbix3.4安装和配置

1、安装zabbix（这里的http://链接注意会更新，可以直接打开网站查询最新的RPM包链接，然后使用rpm -ivh安装即可）

[root@ecs-5c78-0001 ~]# rpm -ivh http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-1.el7.centos.noarch.rpm
Retrieving http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-1.el7.centos.noarch.rpm
Preparing...                          ################################# [100%]
Updating / installing...   1:zabbix-release-3.4-1.el7.centos  ################################# [100%]

[root@ecs-5c78-0001 ~]# yum install zabbix-server-mysql zabbix-web-mysql -y

2、创建数据库

[root@ecs-5c78-0001 ~]# mysql
Welcome to the MariaDB monitor.  Commands end with ; or \g.

Your MariaDB connection id is 2

Server version: 5.5.56-MariaDB MariaDB Server

Copyright (c) 2000, 2017, Oracle, MariaDB Corporation Ab and others.

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

MariaDB [(none)]> create database zabbix character set utf8 collate utf8_bin;

Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix';

Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> exit

Bye

3、导入数据库（这里的zabbix-mysql-3.4.5注意版本号会更新）

[root@ecs-5c78-0001 ~]# zcat /usr/share/doc/zabbix-server-mysql-3.4.5/create.sql.gz |mysql -uzabbix -pzabbix zabbix

4、配置数据库用户及密码

[root@ecs-5c78-0001 ~]# vim /etc/zabbix/zabbix_server.conf

5、修改如下配置

DBName=zabbix

DBUser=zabbix

#DBPassword= 改为》》DBPassword=zabbix

保存退出：wq

6、启动zabbix server 并设置开机启动

[root@ecs-5c78-0001 ~]# systemctl start zabbix-server.service 
[root@ecs-5c78-0001 ~]# systemctl enable zabbix-server.service 
Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-server.service to /usr/lib/systemd/system/zabbix-server.service.

7、编辑zabbix前端PHP配置，更改时区

[root@ecs-5c78-0001 ~]# vim /etc/httpd/conf.d/zabbix.conf

# php_value date.timezone Europe/Riga 改为》》 php_value date.timezone Asia/Shanghai

保存退出：wq

更改为如下

8、Selinux配置

[root@ecs-5c78-0001 ~]# setsebool -P httpd_can_connect_zabbix on

setsebool:  SELinux is disabled.

[root@ecs-5c78-0001 ~]# setsebool -P httpd_can_cetwork_connect_db on

setsebool:  SELinux is disabled.

9、启动httpd并且设置开机启动

[root@ecs-5c78-0001 ~]# systemctl start httpd
[root@ecs-5c78-0001 ~]# systemctl enable httpd
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.

四、配置Zabbix Web信息

1.浏览器登录本机IP：http://192.168.2.216/zabbix/

2.点击：Next step

3.点击：Next step

4.点击：Next step

5.确认输入信息，点击Next step

6.点击Finish，生成配置文件在：/etc/zabbix/web/zabbix.conf.php

查看配置文件：

cat /etc/zabbix/web/zabbix.conf.php

登录Zabbix3.4，默认用户名：Admin 默认密码：zabbix

登录页面

更换为中文

Zabbix服务器端安装完成！

五、安装及设置Zabbix-agent

安装zabbix-agent

[root@ecs-5c78-0002 ~]#  rpm -ivh  https://mirrors.aliyun.com/zabbix/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-1.el7.centos.noarh.rpm
Retrieving https://mirrors.aliyun.com/zabbix/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-1.el7.centos.noarch.rpm
Preparing...                          ################################# [100%]
Updating / installing...
   1:zabbix-release-3.4-1.el7.centos  ################################# [100%]
[root@ecs-5c78-0002 ~]#  yum install zabbix-agent –y

或者使用官网提供的链接，然后rpm -ivh进行安装：rpm -ivh http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-agent-3.4.0-1.el7.x86_64.rpm

配置zabbix-agent

[root@ecs-5c78-0002 ~]# vim /etc/zabbix/zabbix_agentd.conf

修改server IP地址

修改为zabbix-server服务端的IP地址

修改ServerActive IP地址

修改为zabbix-server服务器端的IP地址

启动zabbix-agent并设置开机启动

[root@ecs-5c78-0002 ~]# systemctl start zabbix-agent.service 
[root@ecs-5c78-0002 ~]# 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.
