CentOS 7 下快速搭建 Zabbix 3.0 环境

本笔记是基于CentOS 7下最小化安装的操作系统搭建的Zabbix3.0环境,用于做一些监控项的测试及运维自动化的测试。

前面是学习步骤的记录,后面有快速部署的命令,安装操作系统后,copy/paste就可以快速搭建一个LAMP或LNMP的Zabbix环境。

基于LAMP环境的Zabbix3.0

LAMP环境安装

1
[root@master ~]# yum install httpd mariadb mariadb-server mariadb-client php php-mysql

安装Zabbix服务

[root@master ~]# rpm -ivh http://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm
[root@master ~]# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
[root@master ~]# yum install zabbix-server-mysql zabbix-web-mysql zabbix-get zabbix-agent

MariaDB [(none)]> CREATE DATABASE zabbix DEFAULT CHARACTER SET utf8 COLLATE utf8_bin;
MariaDB [(none)]> GRANT ALL ON zabbix.* TO 'zabbix'@'%' IDENTIFIED BY 'zabbix';
MariaDB [(none)]> quit

[root@master ~]# cd /usr/share/doc/zabbix-server-mysql-3.0.3/
[root@master zabbix-server-mysql-3.0.3]# zcat create.sql.gz | mysql -uroot -p zabbix
[root@master zabbix-server-mysql-3.0.3]# cd

[root@master ~]# vim /etc/zabbix/zabbix_server.conf
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix

上述配置文件中,我们只需要关注DBHost、DBName、DBUser、DBPassword几项即可。这几项是配置zabbix server连接mysql数据库的参数。

1

[root@master ~]# vim /etc/httpd/conf.d/zabbix.conf
php_value date.timezone Asia/Chongqing

其中php_value date.timezone Asia/Chongqing主要是定义php的时区

启动

1
2
3
[root@master ~]# systemctl start httpd
[root@master ~]# systemctl start zabbix-server
[root@master ~]# systemctl start zabbix-agent

通过 http://ip/zabbix 访问
默认用户名/密码:Admin/zabbix,注意用户名也区分大小写

# 配置中重写了访问路径
[root@master ~]# vim /etc/httpd/conf.d/zabbix.conf
Alias /zabbix /usr/share/zabbix

基于LNMP环境的Zbbix3.0

LNMP环境安装

1
2
[root@master ~]# yum install nginx mariadb mariadb-server mariadb-client php php-mysql php-fpm -y
/run/php-fpm/php-fpm.pid

[root@master ~]# rpm -ivh http://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm
[root@master ~]# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
[root@master ~]# yum install zabbix-server-mysql zabbix-web-mysql zabbix-get zabbix-agent

修改文件属主和属组

zabbix的rpm包里默认编译apache为文件拥有者,把httpd服务替换为nginx服务,相应文件的拥有者需要进行对应的更改。

[root@client01 ~]# systemctl start zabbix-agent

Zabbix-Get的使用

Zabbix-Get是Zabbix中的一个应用程序,用于Zabbix-Server到Zabbix-Agent的数据获取,通常可以用来测试Agent的配置是否正确。
