## 修改配置文件 允许执行远程命令
[root@web02 ~]# vim /etc/zabbix/zabbix_agentd.conf
EnableRemoteCommands=1     //随便加加进去就行

# 客户端zabbix用户要sudo提权
[root@web02 ~]# visudo
%zabbix ALL=(ALL) NOPASSWD:ALL

# 客户端zabbix用户要/bin/bash登录
[root@web02 ~]# usermod zabbix -s /bin/bash

# 3.测试
[root@web02 ~]# su - zabbix -c 'sudo ls -l /'
su: warning: cannot change directory to /var/lib/zabbix: No such file or directory
