centos下安装nginx遇见的问题及解决方法

mac下安装centos的虚拟机，mac环境和环境还是很大区别，至少无法安装我想要的FastDFS环境，着实有点无法接受，所以只能安装虚拟机了。

ssh 后，安装遇到了如下问题：
1、gcc-c++没有安装，会导致安装pcre的时候，报c++编译器没找到，直接安装：yum install gcc-c++即可
2、zlib包无法找到，安装：yum install zlib-devel即可
3、error while loading shared libraries: libpcre.so.1：[root@bogon nginx-1.0.12]# ldd $(which /usr/local/nginx/sbin/nginx)
