Nginx启动脚本

安装REE时自动安装了nginx，却没有nginx的启动脚本，记录下来备忘：

假设nginx安装在/opt/nginx下面

安装nginx到启动项：$sudo update-rc.d nginx defaults

把以下复制到/etc/init.d/nginx，并加上执行权限，$sudo chmod +x /etc/init.d/nginx

#! /bin/sh

### BEGIN INIT INFO

        echo -n "Starting $DESC: "
        test_nginx_config
        start-stop-daemon --start --quiet --pidfile $PID_FILE \

        sleep 1
        test_nginx_config
        start-stop-daemon --start --quiet --pidfile \
                $PID_FILE --exec $DAEMON -- $DAEMON_OPTS || true
        echo "$NAME."
        ;;

        start-stop-daemon --stop --signal HUP --quiet --pidfile $PID_FILE \
            --exec $DAEMON || true
        echo "$NAME."
        ;;
  configtest)
        echo -n "Testing $DESC configuration: "
        if test_nginx_config
        then
          echo "$NAME."
        else
          exit $?
        fi
        ;;
  status)
        status_of_proc -p $PID_FILE "$DAEMON" nginx && exit 0 || exit $?
        ;;
  *)
        echo "Usage: $NAME {start|stop|restart|reload|force-reload|status|configtest}" >&2
        exit 1
        ;;
esac

exit 0

 注意：如果使用/var/run/$NAME.pid的pidfile配置，会出现虽然nginx已经启动，用/etc/init.d/nginx status查询仍然是stop的问题，我想应该是权限的问题，所以改成了/opt/nginx/logs/nginx.pid
