......3.zabbix-agent client (centos 7.6)
1) Install necessary packages
zabbix-agent nginx
2) Configuration agent configuration file
[root@nginx zabbix_agentd.d]# grep '^[a-Z]' /etc/zabbix/zabbix_agentd.conf EnableRemoteCommands=1 #Be sure to turn it on, or you will not be able to execute remote commands Server=192.168.1.14,192.168.1.20 #Specify both server and proxy proxies ServerActive=192.168.1.20 #Proxy proxy proxy side specifying active mode Hostname=192.168.1.16 #Specify a host name to the local computer. The host name added to the web must be the same as the host name here. Otherwise, the data acquisition will fail. Timeout=30 Include=/etc/zabbix/zabbix_agentd.d/*.conf UnsafeUserParameters=1 #Special characters that support remote command transmission must also be turned on
3) Start the two services of agent and nginx
[root@nginx ~]# systemctl restart zabbix-agent [root@nginx ~]# systemctl enable zabbix-agent [root@nginx ~]# systemctl start nginx [root@nginx ~]# systemctl enable nginx
4) View the Started Services

......4.zabbix-server creates an active mode proxy on the web side
5. Creating nginx template on the web side of zabbix-server
1) nginx_status template creation
2) Monitoring item creation
3) Create all nginx monitoring items
4) Create triggers
5) Create two nginx triggers
6) Create the current status graph
7) Creating Cumulative State Graphics
8) Create another nginx listening port status chart
9) Create aggregate graphics
10) Add the previous monitor graphics to the aggregate graphics and click on the constructor
11) Click Change to Enter the Add Interface
12) You can see that monitoring graphics have been successfully added to aggregate graphics.
13) View the created graphics
14) nginx_status status status template creation completed
6.zabbix-server Adding Monitoring Host to web End
1) Add monitoring host zabbix-agent and an active mode agent
2) Add a template
3) Add Completion
7. Viewing data graph of monitoring host zabbix-agent on Web
1) nginx status page cumulative state graph
2) nginx status page current status chart
3) View the nginx listening port status chart and display it as normal
8. Establishing email notification and creating nginx service self-healing action on the web side
1) Click Create Media Type
2) Create media type, fill in media type information, and require qq mailbox to pre-open smtp service
3) You can see that media types have been successfully added
4) Enter the user interface and select admin account
Select admin account
5) Selection of alarm media

8) Add trigger condition under action bar
9) Add a remote command to the action bar
10) Add a downtime notification message to the action bar and specify the recipient of the message.
11) Adding recovery messages to the recovery action bar, also specifying the recipient of the message
9. Testing whether nginx service can receive mail notification and realize self-healing function
1) First shut down the nginx service on the zabbix-agent client
[root@nginx zabbix_agentd.d]# systemctl stop nginx
2) zabbix-agent client quickly checks the status of nginx service, the service has been shut down
[root@nginx ~]# systemctl status nginx
● nginx.service - The nginx HTTP and reverse proxy server
Loaded: loaded (/usr/lib/systemd/system/nginx.service; disabled; vendor preset: disabled)
Active: inactive (dead)
3) After the nginx service was shut down, a dashboard alarm was triggered on the web side.
4) receiving alert mailbox notification, nginx Server Disconnected
5) After 3-5 seconds interval, the nginx service is automatically restarted to achieve self-healing.
[root@nginx zabbix_agentd.d]# systemctl status nginx
● nginx.service - The nginx HTTP and reverse proxy server
Loaded: loaded (/usr/lib/systemd/system/nginx.service; disabled; vendor preset: disabled)
Active: active (running) since Fri 2019-07-19 16:43:10 CST; 12min ago
Process: 50272 ExecStart=/usr/sbin/nginx (code=exited, status=0/SUCCESS)
Process: 50245 ExecStartPre=/usr/sbin/nginx -t (code=exited, status=0/SUCCESS)
Process: 50243 ExecStartPre=/usr/bin/rm -f /run/nginx.pid (code=exited, status=0/SUCCESS)
......
6) View the monitor graph of nginx-8080 on the web side, and the value returns to normal from exceeding the warning line to descending.
7) The dashboard returns to normal automatically
8) Receive notification of successful automatic recovery of malfunction
