ubuntu 下 nginx 自启动设置

在/etc/init.d下面创建nginx文件cd /etc/init.d  sudo touch nginx  sudo chmod +x nginx nginx内容：#! /bin/sh  #  ### BEGIN INIT INFO  # Provides:          nginx  # Required-Start:    $syslog $local_fs $remote_fs  # Required-Stop:     $syslog $local_fs $remote_fs  # Should-Start:      dbus avahi  # Should-Stop:       dbus avahi  # Default-Start:     2 3 4 5  # Default-Stop:      1  # Short-Description: Nginx Server  # Description:       Nginx  ### END INIT INFO    PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/opt/nginx/sbin  DAEMON=/opt/nginx/sbin/nginx  NAME=nginx  DESC="Nginx Server"  PID_FILE=/opt/nginx/logs/nginx.pidtest -x $DAEMON || exit 0  RUN=yes  #RUN_AS_USER=root    #DAEMON_OPTS="-a $RUN_AS_USER"    set -e    case "$1" in    start)      echo -n "Starting $DESC: "      $DAEMON      echo "$NAME."      ;;    stop)      echo -n "Stopping $DESC: "      $DAEMON -s stop      echo "$NAME."      ;;    force-reload)      $DAEMON -s reload   echo "";;    restart)      echo -n "Restarting $DESC: "      $DAEMON -s  stop     sleep 1      $DAEMON  start    echo "$NAME."      ;;    status)      if [ -s $PID_FILE ]; then              RUNNING=$(cat $PID_FILE)              if [ -d /proc/$RUNNING ]; then                  if [ $(readlink /proc/$RUNNING/exe) = $DAEMON ]; then                      echo "$NAME is running."                      exit 0                  fi              fi                # No such PID, or executables don't match              echo "$NAME is not running, but pidfile existed."              rm $PID_FILE              exit 1          else              rm -f $PID_FILE              echo "$NAME not running."              exit 1          fi      ;;    *)      N=/etc/init.d/$NAME      echo "Usage: $N {start|stop|restart|force-reload}" >&2      exit 1      ;;  esac    exit 0

vi /etc/rc.local 

加入一行  /etc/init.d/nginx start    保存并退出，下次重启会生效
