前言

不要使用nginx添加 lua 模块进行编译安装！
nginx 中添加 lua 模块，支持lua脚本以及遇到的坑
比如添加一个lua-resty-jwt令牌校验工具，你需要重新与ngnix进行整合，上面文章只是ngnix和lua的整合
推荐使用OpenResty

安装OpenResty

OpenResty官网
推荐使用官方预编译包安装（发布在yum上面的包）

添加yum仓库

# add the yum repo:
wget https://openresty.org/package/centos/openresty.repo
sudo mv openresty.repo /etc/yum.repos.d/
# update the yum index:
sudo yum check-update

安装opm

安装openresty的包管理工具opm，非常重要，后续通过opm方式下载需要lua所需的工具包

 yum install openresty-opm

OpenResty和Ngnix使用是一样的

# 查看版本和安装的模块
/usr/local/openresty/nginx/sbin/nginx -V
#检查配置
/usr/local/openresty/nginx/sbin/nginx -t
#启动
/usr/local/openresty/nginx/sbin/nginx
#重新加载配置
/usr/local/openresty/nginx/sbin/nginx -s reload
#停止
/usr/local/openresty/nginx/sbin/nginx -s stop

在ngnix执行lua，校验安装成功

    server {
        listen 8080;
        location / {
            default_type text/html;
            content_by_lua_block {
                ngx.say("<p>hello, world</p>")
            }
        }
    }

lua jwt校验

使用opm安装jwt工具

opm get SkyLothar/lua-resty-jwt

运行lua-resty-jwt示例
