①：checking for C compiler … not found

　　yum -y install gcc

　　yum -y install gcc-c++

②：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.

　　yum -y install pcre-devel

③：./configure: error: the HTTP cache module requires md5 functions
　　from OpenSSL library.   You can either disable the module by using
　　--without-http-cache option, or install the OpenSSL library into the system,
　　or build the OpenSSL library statically from the source with nginx by using
　　--with-http_ssl_module --with-openssl=<path> options.

　　yum -y install openssl openssl-devel

　　make

　　make install
