有时候，我们需要单独安装nginx，来处理大量的下载请求。单独在Centos5安装nginx遇到的rewrite和HTTP cache错误解决办法：

　　wget http://nginx.org/download/nginx-0.8.33.tar.gz

　　tar -zxvf nginx-0.8.33.tar.gz

　　cd nginx-0.8.33

　　./configure –prefix=/usr/local/nginx

　　安装Nginx时报错

　　./configure: error: the HTTP rewrite module requires the PCRE library.

　　安装pcre-devel解决问题

　　yum -y install pcre-devel

　　错误提示：./configure: error: the HTTP cache module requires md5 functions

from OpenSSL library.   You can either disable the module by using
–without-http-cache option, or install the OpenSSL library into the system,
or build the OpenSSL library statically from the source with nginx by using
–with-http_ssl_module –with-openssl=<path> options.

　　解决办法：

　　yum -y install openssl openssl-devel

　　总结：

　　yum -y install pcre-devel openssl openssl-devel

　　./configure –prefix=/usr/local/nginx

　　make

　　make install

　　一切搞定
