Linux registry service
Like mysql, ssh, we can use commands like service mysqld start to start, close, etc., so how do we manage our own programs in this way?
1. Enter /etc/init.d, and create a file xxxd whose content is as follows:
#!/bin/bash
# chkconfig: - 90 10
# description: test service
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
RETVAL=0
# The logic executed when calling service xxxd start, generally here we call the startup script of our program with some necessary parameters to start our process, and then write the pid to the corresponding file
start() {
echo "started"
}
#Execute the logic executed when service xxxd stop, generally here we find the corresponding pid file, and then kill the corresponding process
stop() {
echo "stopped"
}
# See how we were called.

exit 1
