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
