nginx启动、重启、关闭

方式一：传统方法

一、启动　　

cd usr/local/nginx/sbin

./nginx

cd usr/local/nginx/sbin./nginx

二、重启

　　更改配置重启nginx　　

kill -HUP 主进程号或进程号文件路径或者使用cd /usr/local/nginx/sbin./nginx -s reload

判断配置文件是否正确　

nginx -t -c /usr/local/nginx/conf/nginx.conf或者cd  /usr/local/nginx/sbin./nginx -t

三、关闭

　　查询nginx主进程号

　　ps -ef | grep nginx

　　从容停止 kill -QUIT 主进程号

　　快速停止 kill -TERM 主进程号

　　强制停止 kill -9 nginx

　　若nginx.conf配置了pid文件路径，如果没有，则在logs目录下

　　kill -信号类型 '/usr/local/nginx/logs/nginx.pid'

方式二：通过配置/etc/init.d/nginx文件来控制

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)

#!/bin/bash  # nginx Startup script for the Nginx HTTP Server  # it is v.0.0.2 version.  # chkconfig: - 85 15  # description: Nginx is a high-performance web and proxy server.  #              It has a lot of features, but it's not for everyone.  # processname: nginx  # pidfile: /var/run/nginx.pid  # config: /usr/local/nginx/conf/nginx.conf  nginxd=/usr/local/nginx/sbin/nginx  nginx_config=/usr/local/nginx/conf/nginx.conf  nginx_pid=/var/run/nginx.pid  RETVAL=0  prog="nginx"  # Source function library.  . /etc/rc.d/init.d/functions  # Source networking configuration.  . /etc/sysconfig/network  # Check that networking is up.  [ ${NETWORKING} = "no" ] && exit 0  [ -x $nginxd ] || exit 0  # Start nginx daemons functions.  start() {  if [ -e $nginx_pid ];then     echo "nginx already running...."     exit 1  fi     echo -n $"Starting $prog: "     daemon $nginxd -c ${nginx_config}     RETVAL=$?     echo     [ $RETVAL = 0 ] && touch /var/lock/subsys/nginx     return $RETVAL  }  # Stop nginx daemons functions.  stop() {          echo -n $"Stopping $prog: "          killproc $nginxd          RETVAL=$?          echo          [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid  }  # reload nginx service functions.  reload() {      echo -n $"Reloading $prog: "      #kill -HUP `cat ${nginx_pid}`      killproc $nginxd -HUP      RETVAL=$?      echo  }  # See how we were called.  case "$1" in  start)          start          ;;  stop)          stop          ;;  reload)          reload          ;;  restart)          stop          start          ;;  status)          status $prog          RETVAL=$?          ;;  *)          echo $"Usage: $prog {start|stop|restart|reload|status|help}"          exit 1  esac  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…
