Ubuntu下配置nginx的时候报错，即执行如下语句时：
sudo ./configure --prefix=/usr/local/src/nginx/ --add-module=/usr/local/src/fastdfs-nginx-module-master/src
报错1：【./configure: error: the HTTP rewrite module requires the PCRE library.】
报错信息如下：
./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.
解决方法：
1.搜查了一下这个问题，有网友说是因为没有安装PCRE函数库
于是按照这位大佬的教程安装了一下https://blog.csdn.net/qq_35606010/article/details/107331827
报错2：【./configure: error: the HTTP gzip module requires the zlib library.】
完了又报错如下：
./configure: error: the HTTP gzip module requires the zlib library.
You can either disable the module by using --without-http_gzip_module
option, or install the zlib library into the system, or build the zlib library
statically from the source with nginx by using --with-zlib=<path> option.
于是又执行了如下命令,至此问题解决。
sudo apt-get install zlib1g-dev
