Nginx server adds Systemd custom service process analysis

1. Take nginx as an example

Nginx installed using the yum command

Systemd service files end with .service. For example, if you want to set up nginx for startup, if you use the yum install command to install it, the yum command will automatically create the nginx.service file. Just use the command:

systemcel enable nginx.service //Start automatically at boot

Compile and install using source code

1. Manually create the nginx.service service file. and put it into /lib/systemd/system folder.

The content of nginx.service is as follows:

[Unit]
Description=nginx
After=network.target

[Service]
Type=forking
ExecStart=/data/nginx/sbin/nginx
ExecReload=/data/nginx/sbin/nginx -s reload
ExecStop=/data/nginx/sbin/nginx -s quit
PrivateTmp=true

[Install]
WantedBy=multi-user.target

PS: Note that the above ExecStart/ExecReload/ExecStop must be based on your own

Corresponding key description

Description:Describe the service
After: Describe the service category
[Service] Setting of service operation parameters
Type=forking means background operation
ExecStart is the specific running command of the service
ExecReload is the restart command
ExecStop is the stop command
PrivateTmp=True means to allocate independent temporary space to the service. Note: All start, restart, and stop commands of [Service] require absolute paths.
[Install] Related settings for service installation under the running level can be set to multi-user, that is, the system running level is 3

Save and exit.

2. Set the startup

systemctl enable nginx.service

Other service commands

systemctl start nginx.service (Start nginx service)
systemctl stop nginx.service (Stop nginx service)
systemctl enable nginx.service (set to start automatically at boot)
systemctl disable nginx.service (stop booting automatically)
systemctl status nginx.service (check the current status of the service)
systemctl restart nginx.service (Restart the service)
systemctl list-units --type=service (view all started services)
