- 在zabbix-agent端添加键值
vim /etc/zabbix/zabbix_agentd.d/mystat.conf
UserParameter=mystat[*],/server/scripts/chk_mysql.sh '$1' # 键值是mystat[]
- 服务端命令行测试键值
[root@zabbix ~]# zabbix_get -s 172.16.1.51 -k mystat[Uptime]
496
- 编写脚本
[root@db01 log]# cat /server/scripts/chk_mysql.sh
#!/bin/bash

- web页面操作添加监控项
二, 判断端口是否存活,
1,方法:一:映射值:
2 ,方法 不用值映射
创建触发器
三,还可以添加远程命令 mysql挂了重启,重启不成功,发送邮件
前提,要改客户端2个配置文件
zabbix-agent配置文件中开启远程命令
EnableRemoteCommands=1
visudo 中添加zabbix用户免密
之前测试这样写成功启动myslq ,启动nginx就失败不知道怎么回事
visudo
## 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
查看日志
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
配置远程命令
此时数据库stop 会zabbix会远程重启数据库, 重启不成功会发邮件提醒
