上篇文章中，Zabbix-server已经配置好了，现用它来监控网络中的linux主机。
在被监控LINUX上安装zabbix-agent
yum -y install zabbix20-agent
vim /etc/zabbix_agentd.conf //更改Server=192.168.110.152(服务端ip) 启动客户端 /etc/init.d/zabbix-agent start 开机自启动 chkconfig zabbix-agent on 服务端上命令行测试：zabbix_get -s 客户端ip -p10050 -k "system.hostname”
因刚开始安装zabbix时，在mysql中创建的同名zabbix账号弱口令，修改密码后，前台php一直报错：
[Z3001] connection to database 'zabbix' failed: [2002] Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
查看zabbix_server.log：

1、 安装zabbix
yum install -y epel-release
安装rpm包的lamp环境
yum install -y httpd mysql mysql-libs php php-mysql mysql-server php-bcmath php-gd php-mbstring
安装zabbix服务端：
yum install zabbix20 zabbix20-agent zabbix20-server zabbix20-server-mysql zabbix20-web zabbix20-web-mysql net-snmp-devel
