安装nginx时，常常会因为缺少依赖组件

新手在尝试安装nginx时，常常会因为缺少依赖组件，导致nginx相应模块无法安装，在执行 ./configure 时常出现错误。若在 ./configure 后方加入了 --with-http_gzip_static_module （添加gzip压缩模块）提示以下错误：./configure: error: the HTTP gzip module requires the zlib library.You can either disable the module by using without-http_gzip_moduleoption, or install the zlib library into the system, or build the zliblibrarystatically from the source with nginx by using with-zlib= option.则需要安装 zlib-devel 即可。SSH执行以下命令：yum install -y zlib-devel
