相信做web开发的没有几个不熟悉nginx,所以这里就不介绍它,也不对他逆天的性能进行追捧了。 另外打算用yum安装nginx也不用看本文。yum可以方便的安装nginx没错,而且也能用的好好的。 但是如果你想在安装nginx过程中做更多自定义的工作,可以继续阅读下去。比如指定安装目录,指定要安装的插件等等。 [摘自百度百科]

下载解压

  • 本文使用1.6.2的版本。

      wget http://nginx.org/download/nginx-1.6.2.tar.gz
        
      tar -zxf nginx-1.6.2.tar.gz
    

安装

  • 准备目录,比如要安装到/opt/nginx/目录下

    mkdir /opt/nginx

  • 安装依赖模块及其源:

    yum install pcre pcre-devel openssl openssl-devel pcre zile-devel gcc

  • 进入刚才的解压的目录进行安装

    /configure –prefix=/opt/nginx –with-http_stub_status_module –with-http_realip_module –with-http_gzip_static_module –with-http_ssl_module make make install

安装服务

  • 新建服务文件:/etc/init.d/nginx并输入下面内容

      #!/bin/sh
      #
      # nginx - this script starts and stops the nginx daemon
      #
      # chkconfig:   - 85 15

      #               proxy and IMAP/POP3 proxy server

      [ "$NETWORKING" = "no" ] && exit 0

      prog=$(basename $nginx)

         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() {

      restart() {
          configtest || return $?
          stop
          sleep 1
          start
      }
        
      reload() {

      }
        
      configtest() {

      }
        
      rh_status() {

  • 赋予权限并且将ngix加入到linux服务中和随机启动列表

       chmod +x /etc/init.d/nginx
       chkconfig --add nginx
       chkconfig nginx on
    

启动并测试nginx

  • 启动nginx很简单:service nginx start 即可。
  • 使用curl命令进行测试:curl http://localhost
  • 测试如果有问题,检查80端口是否开启。

附上一个nginx.conf的典型配置
