-这边并没有使用 `ExecStop=/bin/kill -s QUIT $MAINPID` 这样的命令来停止redis, 因为使用这个语句在运行`systemctl stop redis`后, redis并未执行关闭动作, 而是直接退出. 这时候用 `systemctl status redis` 查看状态是failed. 只有用`ExecStop=/install_path/bin/redis-cli -p 16379 shutdown` 才能正确停止redis

 > **If set to forking, it is expected that the process configured with ExecStart= will call fork() as part of its start-up. The parent process is expected to exit when start-up is complete and all communication channels are set up. The child continues to run as the main daemon process. This is the behavior of traditional UNIX daemons. If this setting is used, it is recommended to also use the PIDFile= option, so that systemd can identify the main process of the daemon. systemd will proceed with starting follow-up units as soon as the parent process exits.**
