./configure: error: the HTTP SSL module requires OpenSSL library
   原因：安装http_ssl_module模块需要openssl library
   解决：yum install openssl-devel
./configure: error: the HTTP rewrite module requires the PCRE library.
   原因：安装http_rewrite_module模块需要先安装PCRE开发包
   解决：yum install pcre-devel

注意：

--with-pcre=/usr/local/src/pcre-.21指向的是源码包解压的路径，而不是安装的路径，否则会报错。

 --add-module=/usr/local/src/ngx_cache_purge-2.1 是指加载缓存的插件模块
