同样的问题 #74 failed to run balancer_by_lua*: /opt/verynginx/verynginx/lua_script/on_banlance.lua:9: module 'ngx.balancer' not found ngx.balancer 这个在lua-nginx-module里面是有的，在这里我这里提供一下完整的Dockerfile和另外两个配置文件，可以保证重现问题。 Dockerfile

运行如下命令：

docker build -t vn .
docker run -d vn

然后在浏览器里操作，添加proxy_pass，即可重现问题了，nginx的log在/var/log/nginx/目录里。

多谢反馈。

我看到你是自己编译了 nginx 以及相关的模块，设置了 NGX_LUA_VERSION=0.10.7 ，这个版本的 lua-nginx-module 模块应该是可以支持 balance 的，就是我不确定里面是否包含了 balance 的代码，balance 的代码在这里:

https://github.com/openresty/lua-resty-core

安装这个库（或者吧 balance 的代码补上）应该能解决问题

我有空了会查一下这个问题，就是会比较慢T_T，你也可以自己动手哈

jim3ma commented 7 years ago

@alexazhou 的确是lua-resty-core没有安装的问题，将lua-resty-core/lib/下的所有文件复制到/usr/local/lib/lua/5.1/目录下就可以了，当然可以是任意lua能识别的目录就可以了，如下的目录都是可以的

/opt/verynginx/verynginx/lua_script/
/opt/verynginx/verynginx/lua_script/module/
/usr/local/share/luajit-2.1.0-beta2/
/usr/local/share/lua/5.1/
...

看来wiki和readme需要完善一下了哦。

你说的对，是该完善啦。

我这边尝试把lua-resty-core/lib/下的文件复制到/opt/verynginx/verynginx/lua_script/下，会出现如下报错：
