./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.

  解决办法：

     sudo apt-get update

     sudo apt-get install libpcre3 libpcre3-dev
