4. web页面操作添加监控项

在对应的主机上创建监控项

## Same thing without a password #%wheel ALL= (ALL) NOPASSWD: ALL zabbix ALL=(ALL) NOPASSWD: ALL

停止nginx,没有远程执行命令

[root@web01 ~]# systemctl stop nginx

Jan 12 04:03:42 web01 sudo: pam_unix(sudo:auth): conversation failed
Jan 12 04:03:42 web01 sudo: pam_unix(sudo:auth): auth could not identify password for [zabbix]
Jan 12 04:03:42 web01 sudo: pam_succeed_if(sudo:auth): requirement "uid >= 1000" not met by user "zabbix"

后来改了visudo文件

[root@web01 ~]# visudo 
## Same thing without a password
#%wheel ALL=(ALL)       NOPASSWD: ALL
zabbix ALL=NOPASSWD: ALL

查看日志,远程支持命令成功

[root@web01 ~]# tail -f /var/log/secure
ticationAgent, locale en_US.UTF-8) (disconnected from bus)Jan 12 15:04:26 web01 sudo: zabbix : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/bin/systemctl restart nginx.service
