Nginx使用

Nginx

Nginx安装

• 安装前准备
  • 依赖gcc openssl-devel pcre-devel zlib-devel
  • 安装：yum install gcc openssl-devel pcre-devel zlib-devel -y
• 安装Nginx
  • 默认安装目录 /usr/local/nginx

   ./configure
   make && make install
  

• 配置Nginx为系统服务，方便管理

1. 在/etc/rc.d/init.d/目录中建立文本文件nginx
2. vim nginx 文件中粘贴下面内容：

   #!/bin/sh
   #
   # nginx - this script starts and stops the nginx daemon
   #
   # chkconfig:   - 85 15 
   # description:  Nginx is an HTTP(S) server, HTTP(S) reverse \
   #               proxy and IMAP/POP3 proxy server
   # processname: nginx
   # config:      /etc/nginx/nginx.conf
   # config:      /etc/sysconfig/nginx
   # pidfile:     /var/run/nginx.pid
    
   # Source function library.
   . /etc/rc.d/init.d/functions
    
   # Source networking configuration.
   . /etc/sysconfig/network
    
   # Check that networking is up.
   [ "$NETWORKING" = "no" ] && exit 0
    
   nginx="/usr/local/nginx/sbin/nginx"
   prog=$(basename $nginx)
    
   NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"
    
   [ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
    
   lockfile=/var/lock/subsys/nginx
    
   make_dirs() {
      # make required directories
      user=`nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`
      options=`$nginx -V 2>&1 | grep 'configure arguments:'`
      for opt in $options; do
          if [ `echo $opt | grep '.*-temp-path'` ]; then
              value=`echo $opt | cut -d "=" -f 2`
              if [ ! -d "$value" ]; then
                  # echo "creating" $value
                  mkdir -p $value && chown -R $user $value
              fi
          fi
      done
   }
    
   start() {
       [ -x $nginx ] || exit 5
       [ -f $NGINX_CONF_FILE ] || exit 6
       make_dirs
       echo -n $"Starting $prog: "
       daemon $nginx -c $NGINX_CONF_FILE
       retval=$?
       echo
       [ $retval -eq 0 ] && touch $lockfile
       return $retval
   }
    
   stop() {
       echo -n $"Stopping $prog: "
       killproc $prog -QUIT
       retval=$?
       echo
       [ $retval -eq 0 ] && rm -f $lockfile
       return $retval
   }
    
   restart() {
       configtest || return $?
       stop
       sleep 1
       start
   }
    
   reload() {
       configtest || return $?
       echo -n $"Reloading $prog: "
       killproc $nginx -HUP
       RETVAL=$?
       echo
   }
    
   force_reload() {
       restart
   }
    
   configtest() {
     $nginx -t -c $NGINX_CONF_FILE
   }
    
   rh_status() {
       status $prog
   }
    
   rh_status_q() {
       rh_status >/dev/null 2>&1
   }
    
   case "$1" in
       start)
           rh_status_q && exit 0
           $1
           ;;
       stop)
           rh_status_q || exit 0
           $1
           ;;
       restart|configtest)
           $1
           ;;
       reload)
           rh_status_q || exit 7
           $1
           ;;
       force-reload)
           force_reload
           ;;
       status)
           rh_status
           ;;
       condrestart|try-restart)
           rh_status_q || exit 0
               ;;
       *)
           echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
           exit 2
   esac
   

   3. 修改nginx文件的执行权限

   chmod +x nginx
   

   4. 添加改文件到系统服务中

   chkconfig --add nginx
   #查看是否添加成功
   chkconfig --list nginx
   

   5. 启动、停止、重新装载命令

   service nginx start|stop|reload
