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，b2b信息网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 -y

　　5：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

　　9：zabbix-server上的zabbix-agent启用远程命令功能：

vim /etc/zabbix/zabbix_agentd.conf EnableRemoteCommands=1 AllowRoot=1 ​ systemctl restart zabbix-agent.service

　　10:在zabbix-web上配置触发器动作

　　整体效果如下：

　　远程命令细节：

命令：ansible web -m shell -a systemctl restart httpd.service

　　11: 测试zabbix-agent报警升级

　　测试1：

　　停止httpd服务

[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

　　查看httpd服务状态

[root@oldboy ~]# systemctl status httpd ● httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled) Active: active (running) since Tue 2019-08-06 22:20:13 CST; 295ms ago Docs: man:httpd(8) man:apachectl(8) Process: 2839 ExecStop=/bin/kill -WINCH ${MAINPID} (code=exited, status=0/SUCCESS) Main PID: 2894 (httpd) Status: "Processing requests..."

　　测试2：

　　停止httpd服务

[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 ​ #使用nc监听80端口，模拟httpd重启失败 yum install nc -y nc -l 80

　　至此,预处运已经实现httpd停止服务，zabbix执行远程命令进行恢复，香港云服务器理和老男1分钟之后如果恢复失败，升级发邮件给运行，培训1分钟之后，故障问题没解决发邮件给领导
