1. 安装pcre-8.12.tar.gz
    直接执行以下命令： （到目录下）
    # tar -zxvf pcre-8.21.tar.gz
    # cd pcre-8.21
    # ./configure
    # make
    # make install
    2. 安装zlib-1.2.8.tar.gz
    wget http://zlib.net/zlib-1.2.8.tar.gz
    # tar -xf zlib-1.2.8.tar.gz
    # cd zlib-1.2.8
    # ./configure
    # make
    # make install
    3. 安装openssl-1.0.1c.tar.gz
    wget http://www.openssl.org/source/openssl-1.0.1c.tar.gz
    # tar -zxvf openssl-1.0.1c.tar.gz
    # cd openssl-1.0.1c
    # ./config
    # make
    # make install
    4. 安装依赖环境
    yum -y install gcc gcc-c++ autoconf automake
    yum -y install zlib-devel openssl openssl-devel pcre-devel
    安装不成功则需要手动一个一个进行安装
    5. 安装nginx-1.2.8.tar.gz
    wget http://nginx.org/download/nginx-1.2.8.tar.gz
    # tar -zxvf nginx-1.2.8.tar.gz
    # cd nginx-1.2.8
    # ./configure —prefix=/usr/local/nginx
    也可以这样写：
    Linux下安装部署Nginx反向代理服务器 - 图1
    # make
    # make install
    6. 检测是否安装成功
    # cd 目录/nginx/sbin
    # ./nginx -t
    如果出现以下提示，表示安装成功：
    Linux下安装部署Nginx反向代理服务器 - 图2
    7. 启动Nginx
    # ./nginx
    重启Nginx
    /usr/local/nginx/sbin/nginx -s reload
    检查修改配置文件是否正确：
    nginx -t
    8. 查看端口号：
    # netstat -ntlp
    出现如下样式即可：
    Linux下安装部署Nginx反向代理服务器 - 图3
    9. 打开浏览器访问设置IP，如果浏览器出现 Welcome to nginx! 则表示 Nginx 已经安装并运行成功。（默认端口为80）
    #全局错误日志及PID文件
    pid /var/run/nginx.pid;
    error_log /var/log/nginx/error.log;
