nginx安装步骤和遇到的问题
tar -xvf nginx-1.15.1.tar.gz cd nginx-1.15.1 ./configrue make make install
在configure中可能遇到的问题：
(1) ./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= option.
解决办法：安装pcre-devel
yum -y install pcre-devel
(2) ./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= option.
解决办法：安装zlib-devel
yum install -y zlib-devel
