1. 安裝依賴庫

  yum -y install gcc-c++
  yum -y install pcre pcre-devel
  yum -y install zlib zlib-devel
  yum -y install openssl openssl-devel

2. 安裝nginx

  cd /data

  wget http://nginx.org/download/nginx-1.12.0.tar.gz 

  tar -zxvf nginx-1.12.0.tar.gz

  cd nginx-1.12.0
  ./configure
  make
  make install

3. 優化nginx配置
