编译nginx时出现pcre找不到的解决方法

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

安装pcre-devel解决问题
yum -y install pcre-devel

还有可能出现：

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
