实验效果：实现httpd停止服务，故障zabbix执行远程命令进行恢复，预处运1分钟之后如果恢复失败，理和老男发邮件给运行，升级1分钟之后，云南idc服务商培训问题没解决发邮件给领导 1. 环境规划
2.zabbix-server安装 略 3：zabbix-agent安装 略 4：zabbix-agent上httpd安装 yum install httpd -y5：自定义监控项 vim /etc/zabbix/zabbix_agentd.conf UserParameter=httpd,故障ps -ef|grep -v grep|grep -c /usr/sbin/httpd systemctl restart zabbix-agent
6：创建自定义触发器
7: 创建邮件报警 a：创建发件人
b：创建两个收件人
boss用户需要超级管理权限
8：在zabbix-server上使用ansible远程重启httpd yum install ansible -y vim /etc/ansible/hosts [web] 192.168.100.12 ansible_ssh_user=root ansible_ssh_pass=123456 ansible web -m shell -a systemctl restart httpd.service客户端效果 [root@oldboy ~]# systemctl status httpd ● httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled) Active: activating (start) since Tue 2019-08-06 22:20:08 CST; 4s ago Docs: man:httpd(8) man:apachectl(8) Process: 2839 ExecStop=/bin/kill -WINCH ${MAINPID} (code=exited, status=0/SUCCESS) Main PID: 2894 (httpd) CGroup: /system.slice/httpd.service └─2894 /usr/sbin/httpd -DFOREGROUND Aug 06 22:20:08 oldboy systemd[1]: Starting The Apache HTTP Server...
