[Service]
Type=forking
PIDFile=/application/nginx/logs/nginx.pid
ExecStart=/application/nginx/sbin/nginx -c /application/nginx/conf/nginx.conf
ExecReload=/bin/sh -c "/bin/kill -s HUP $(/bin/cat $PIDFile)"
ExecStop=/bin/sh -c "/bin/kill -s TERM $(/bin/cat $PIDFile)"

[Install]
WantedBy=multi-user.target

检查

[root@web02 ~]$systemctl enable nginx
