About centos7 adding a service as a system service

1. First, we will introduce the system service startup and shutdown changes in centos7.

Service name start/stop/status = systemctl start/stop/status service name

Chkconfig -- list = systemctl list-units-type

Chkconfig service name on/off = systemctl enable/disable service name (the specific level depends on the configuration file)

2. To add a service as a system service (using nginx as an example), you need to add a file ending with. Service, which is much easier than the previous sysv.
