有時候，我們需要單獨安裝nginx，來處理大量的下載請求。單獨在Centos5安裝nginx遇到的rewrite和HTTP cache錯誤解決辦法：

　　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

　　安裝Nginx時報錯

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

　　安裝pcre-devel解決問題

　　yum -y install pcre-devel

　　錯誤提示：./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.

　　解決辦法：

　　yum -y install openssl openssl-devel

　　總結：

　　yum -y install pcre-devel openssl openssl-devel

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

　　make

　　make install

　　一切搞定
