一、前言

在上一篇博客中，講述了在服務(wù)器上安裝多個(gè)tomcat，現(xiàn)在這篇博客要講是安裝nginx

二、配置Nginx的安裝環(huán)境

安裝Nginx需要先將官網(wǎng)下載的源碼進(jìn)行編譯，編譯依賴gcc環(huán)境，如果沒(méi)有g(shù)cc環(huán)境，需要安裝gcc：yum install gcc-c++ ，安裝完gcc后，才可以進(jìn)行下一步的安裝

三、編譯安裝

1. 解壓縮

   將Nginx安裝包nginx-1.8.0.tar.gz拷貝至服務(wù)器上
   解壓縮安裝包：
   tar -zxvf nginx-1.8.0.tar.gz
cd nginx-1.8.0

2. 配置安裝參數(shù)
   參數(shù)如下:

   ./configure \
   --prefix=/usr/local/nginx \
   --pid-path=/var/run/nginx/nginx.pid \
   --lock-path=/var/lock/nginx.lock \
   --error-log-path=/var/log/nginx/error.log \
   --http-log-path=/var/log/nginx/access.log \
   --with-http_gzip_static_module \
   --http-client-body-temp-path=/var/temp/nginx/client \
   --http-proxy-temp-path=/var/temp/nginx/proxy \
   --http-fastcgi-temp-path=/var/temp/nginx/fastcgi \
   --http-uwsgi-temp-path=/var/temp/nginx/uwsgi \
   --http-scgi-temp-path=/var/temp/nginx/scgi
   
   

   注：上邊將臨時(shí)文件目錄指定為/var/temp/nginx，需要在/var下創(chuàng)建temp及nginx目錄

3. 編譯安裝
   make
make install

四、啟動(dòng)Nginx

　　cd /usr/local/nginx/sbin/
　　./nginx

五、停止Nginx

cd /usr/local/nginx/sbin

./nginx -s stop

此方式相當(dāng)于先查出nginx進(jìn)程id再使用kill命令強(qiáng)制殺掉進(jìn)程。

方式2，完整停止(建議使用)：
cd /usr/local/nginx/sbin
./nginx -s quit
此方式停止步驟是待nginx進(jìn)程處理任務(wù)完畢進(jìn)行停止。

六、重啟Nginx

方式1，先停止再啟動(dòng)（建議使用）：

對(duì)nginx進(jìn)行重啟相當(dāng)于先停止nginx再啟動(dòng)nginx，即先執(zhí)行停止命令再執(zhí)行啟動(dòng)命令。
如下：

./nginx -s quit./nginx

方式2，重新加載配置文件：

當(dāng)nginx的配置文件nginx.conf修改后，要想讓配置生效需要重啟nginx，使用-s reload不用先停止nginx再啟動(dòng)nginx即可將配置信息在nginx中生效，如下：

./nginx -s reload

七、開(kāi)機(jī)自啟Nginx

1. 編寫shell文件

   vi /etc/init.d/nginx

   #!/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
   
   
   

   

2. 設(shè)置文件訪問(wèn)權(quán)限

   chmod a+x /etc/init.d/nginx (a+x ==> all user can execute 所有用戶可執(zhí)行)

3. 加入到自動(dòng)列表中

   vi /etc/rc.local

   加入一行 /etc/init.d/nginx start 保存并退出，下次重啟會(huì)生效。
