CentOS 7 安装Nginx报错：
./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.
解决方案：
在控制台输入命令，安装“zlib-devel” 即可：
yum install -y zlib-devel
