Zabbix Zabbix Seven --- Nginx failure to achieve self-healing

Combat: Zabbix Nginx failure to achieve self-healing

1, to create a self-healing fault recovery scripts on the page zabbix

(1) create action on zabbix page, continue the experiment on the basis of Zabbix Six on: https: //www.cnblogs.com/struggle-1216/p/12359472.html

  

 

(2) Configuration action, add triggers, when listening on port 80 to perform a certain action does not exist

    

 

(3) create a scripting operations

    

(4) modify the configuration file /etc/zabbix/zabbix_agentd.conf

Server = 192.168.7.100,192.168.7.103,192.168.7.104 # zabbix server is the first server IP address, the second is the IP address of the database, and the third is the active mode proxy proxy IP address 
ServerActive = 192.168.7.104 # proxy active mode IP address 
Hostname = 192.168.7.101 # local host IP address 
EnableRemoteCommands = 1 # turn on the remote connectivity 
UnsafeUserParameters = 1 # open, supporting special characters such as: pipe character, single and double quotation marks and so on.

Restart zabbix-agent services: systemctl restarrt zabbix-agent

(5) View zabbix zabbix start at this time is user-initiated, due to the general user account is unable to start zabbix server, so need to grant root privileges to zabbix, or start zabbix service as root can be.

   

 (6) modify / etc / sudoers configuration file, let zabbix run as root

root    ALL=(ALL)       ALL
zabbix  ALL=(ALL)       NOPASSWD:ALL # 授权zabbix用户为root的权限

 （7）将nginx服务停掉

   

 （8）创建的zabbix网页上的自治愈脚本就会生效，等待1-2分钟，nginx就会自动启动，实现了基本上的nginx宕机之后能再次启动的效果，这种方法也适用于JAVA、tomcat、redis等服务器上的自治愈，针对某些功能执行某些脚本即可。
