1.安装centos-release-scl

yum install -y centos-release-scl

2.安装部署zabbix服务端

# zabbix 监控的支持有：网络设备（路由器、交换机、防火墙），服务器（windows、Linux系统）

添加监控项

# 客户端自定义监控取值
1）通过shel1命令获取到关键数据
2）将命令与key名在配置文件中定义好
3）服务端通过zabbix-get命令测试获取键值对

# 添加客户端的zabbix_agentd.conf配置文件
cat -n /etc/zabbix/zabbix_agentd.conf |grep UserParameter
342 UserParameter=User_num,w|awk 'NR==1{print $4}'

# 修改完成后需要重启zabbix-agent2服务
systemctl restart zabbix-agent2.service
 
# 服务端安装
yum install -y zabbix-get

# 在服务端使用：zabbix-get的命令，有多少连接数
[root@AdminController nginx]# zabbix_get -s 192.168.255.130 -k User_num
