1、下載 wget https://openresty.org/download/openresty-1.13.6.2.tar.gz
2、解壓 tar -xzf openresty-1.13.6.2.tar.gz
3、編譯 ./configure （查看幫助 ./configure --help 默認安裝在 /usr/local/openresty）
如果編譯失敗：
錯誤提示：/configure: error: the HTTP rewrite module requires the PCRE library.
安裝pcre-devel解決問題
yum -y install pcre-devel
錯誤提示：./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.
解決辦法：
yum -y install openssl openssl-devel
4、編譯 make
5、安裝 make install
