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= options.

解决办法：

yum -y install openssl openssl-devel
