编译时候如下错误:
./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.
重新编译，指定 --with-pcre, 其中 --with-pcre=/vagrant/download/pcre-8.35 是pcre是的源码目录，不是安装目录
[vagrant@localhost nginx-1.7.0]$ ./configure --prefix=/usr/local/nginx --with-pcre=/vagrant/download/pcre-8.35
这样就不报错了。
