Compiled and installed services are managed by systemctl

In our door, we usually compile and install a service, and it may be troublesome to start and restart. To call commands, or to manage the service by writing scripts, then we do not write scripts, but only add a systemctl configuration file to manage the compiled and installed services. Take nginx as an example.

We install the nginx compilation into the / usr/local/nginx directory, and we may need / usr/local/nginx/sbin to start when we start, or make a pathecho $PATH output path variable for the nginx command, and add export PATH=$PATH:/usr/lcoal/nginx/sbin/nginx to the profile file so that we can use the nginx command directly, and we use systemctl to manage the nginx. We need to modify the systemctl configuration file * * / usr/lib/systemd/system** this directory is the configuration information of multiple services, we create a nginx configuration file, * * it is best to name the service name * * ``vim nginx.service [unit] Description=nginxAfter= network.target [service] Type=forkingExecStart=/usr/lcoal/nginx/sbin/nginx # here is the startup command Not the absolute path of the command [Install] WantedBy=multi- user.target```If your service is mysql, of course, if it is mysql, you only need to change Description and ExecStart**ExecStart=/usr/local/mysqld start * * systemctl start nginxps aux | grep nginx to check whether the process is present.
