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

----------------------------------------------------------------解除安裝-------------------------------------------------------------

解除安裝：

刪除nginx目錄即可

rm -rf /opt/nginx

(rm -rf /usr/local/nginx)

如果配置了自啟動，也需要刪除
