手动安装配置nginx

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
    # description:  Nginx is an HTTP(S) server, HTTP(S) reverse \
    #               proxy and IMAP/POP3 proxy server
    # processname: nginx
    # config:      /opt/nginx/conf/nginx.conf
    # pidfile:     /opt/nginx/logs/nginx.pid

    . /etc/rc.d/init.d/functions
      
    # Source networking configuration.
    . /etc/sysconfig/network
      
    # Check that networking is up.
    [ "$NETWORKING" = "no" ] && exit 0
      
    nginx="/opt/nginx/sbin/nginx"
    prog=$(basename $nginx)
      
    NGINX_CONF_FILE="/opt/nginx/conf/nginx.conf"
      
    [ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
      
    lockfile=/var/lock/subsys/nginx
      
    make_dirs() {
       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
            ;;

            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
  

• 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
