开机自启动nginx
这里使用的是编写shell脚本的方式来处理
vi /etc/init.d/nginx  (输入下面的代码)

  1. #!/bin/bash
  2. # nginx Startup script for the Nginx HTTP Server
  3. # it is v.0.0.2 version.
  4. # chkconfig: - 85 15
  5. # description: Nginx is a high-performance web and proxy server.
  6. # It has a lot of features, but it's not for everyone.
  7. # processname: nginx
  8. # pidfile: /var/run/nginx.pid
  9. # config: /usr/local/nginx/conf/nginx.conf
  10. nginxd=/usr/local/nginx/sbin/nginx
  11. nginx_config=/usr/local/nginx/conf/nginx.conf
  12. nginx_pid=/var/run/nginx.pid
  13. RETVAL=0
  14. prog="nginx"
  15. # Source function library.
  16. . /etc/rc.d/init.d/functions
  17. # Source networking configuration.
  18. . /etc/sysconfig/network
  19. # Check that networking is up.
  20. [ ${NETWORKING} = "no" ] && exit 0
  21. [ -x $nginxd ] || exit 0
  22. # Start nginx daemons functions.
  23. start() {
  24. if [ -e $nginx_pid ];then
  25.    echo "nginx already running...."
  26.    exit 1
  27. fi
  28.    echo -n $"Starting $prog: "
  29.    daemon $nginxd -c ${nginx_config}
  30.    RETVAL=$?
  31.    echo
  32.    [ $RETVAL = 0 ] && touch /var/lock/subsys/nginx
  33.    return $RETVAL
  34. }
  35. # Stop nginx daemons functions.
  36. stop() {
  37.         echo -n $"Stopping $prog: "
  38.         killproc $nginxd
  39.         RETVAL=$?
  40.         echo
  41.         [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid
  42. }
  43. # reload nginx service functions.
  44. reload() {
  45.     echo -n $"Reloading $prog: "
  46.     #kill -HUP `cat ${nginx_pid}`
  47.     killproc $nginxd -HUP
  48.     RETVAL=$?
  49.     echo
  50. }
  51. # See how we were called.
  52. case "$1" in
  53. start)
  54.         start
  55.         ;;
  56. stop)
  57.         stop
  58.         ;;
  59. reload)
  60.         reload
  61.         ;;
  62. restart)
  63.         stop
  64.         start
  65.         ;;
  66. status)
  67.         status $prog
  68.         RETVAL=$?
  69.         ;;
  70. *)
  71.         echo $"Usage: $prog {start|stop|restart|reload|status|help}"
  72.         exit 1
  73. esac
  74. exit $RETVAL
:wq  保存并退出
设置文件的访问权限
chmod a+x /etc/init.d/nginx   (a+x ==> all user can execute  所有用户可执行)

这样在控制台就很容易的操作nginx了:查看Nginx当前状态、启动Nginx、停止Nginx、重启Nginx…

同样的修改了nginx的配置文件nginx.conf,也可以使用上面的命令重新加载新的配置文件并运行,可以将此命令加入到rc.local文件中,这样开机的时候nginx就默认启动了
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。
