angie nginx_lua 模块使用

标签：luarocks lua share nginx usr angie local

angie 包含了不少社区模块，docker 镜像更加方便，都已经安装了，以下是一个测试lua 模式的使用
因为默认官方构建的是一个动态扩展模块，对于三方lua 模块安装不是很方便，我参考了openresty
对于luarocks 的支持，这样我们自己安装三方lua 模块就比较方便的

构建支持luarocks 的dcoker 镜像

为了方便我是直接基于docker 版本的rocky 镜像修改的，直接通过docker 构建已经安装luarocks，其他系统的类似

• Dcokerfile
  基于luarocks 构建部分我直接复制了openresty 的luajit 目录的文件

 

FROM docker.angie.software/angie:1.3.1-rocky

RUN mkdir -p /run/angie/

# copy from openresty add cjson 

COPY openresy-lua/luajit/ /usr/share/angie/lualib/

COPY luarocks-3.9.2.tar.gz /tmp/luarocks-3.9.2.tar.gz

RUN yum install -y wget gcc unzip  \

   && cd  /tmp/ && tar -zxvf  luarocks-3.9.2.tar.gz \

   && cd luarocks-3.9.2 \

   && ./configure --prefix=/usr/share/angie/lualib/ \

      --with-lua=/usr/share/angie/lualib/ \

      --lua-suffix=jit \

      --with-lua-include=/usr/share/angie/lualib/include/luajit-2.1 \

    && make build \

    && make install \

    && cd /tmp \

    && rm -rf  luarocks-3.9.2.tar.gz luarocks-3.9.2 \

    && ln -s /usr/share/angie/lualib/share/lua/5.1 /usr/share/lua/5.1

# 此处方便找一些c库依赖

ENV LUA_CPATH="/usr/share/angie/lualib/?.so;/usr/share/angie/?.so;./?.so;/usr/local/lib/lua/5.1/?.so;/usr/share/angie/lualib/lib/?.so;/usr/local/lib/lua/5.1/loadall.so;/usr/share/angie/lualib/lib/lua/5.1/?.so"

lua 模块开发服务

• 应用Dockerfile

FROM dalongrong/angie:1.3.1-rocky-luarocks

# 安装了hashids 以及lua-resty-http，基于上边构建好的luarocks

RUN /usr/share/angie/lualib/bin/luarocks install  lua-resty-hashids \

   && /usr/share/angie/lualib/bin/luarocks install lua-resty-http

• 开启lua 模块
  angie.conf

 

load_module modules/ndk_http_module.so;

load_module modules/ngx_http_lua_module.so;

• location 集成
  angie 默认的default.conf

 

server {

    listen       80;

    server_name  localhost;

    location / {

        root   /usr/share/angie/html;

        index  index.html index.htm;

    }

    location /status/ {

        api     /status/;

        allow   127.0.0.1;

        deny    all;

    }

    error_page   500 502 503 504  /50x.html;

    location = /50x.html {

        root   /usr/share/angie/html;

    }

   # cjson hashids 测试

    location /demo {

        default_type text/html;

        content_by_lua_block {

            local cjson = require("cjson")

            local hashids = require("hashids");

            local h = hashids.new("this is my salt")

            local hash = h:encode(1337)

            local conf = {

                name = "dalong",

                age =333,

                id = hash,

            }

            ngx.say(cjson.encode(conf))

        }   

    }

   # http 请求测试

   location = /http {

        default_type text/html;

        content_by_lua_block {

            local httpc = require("resty.http").new()

            -- Single-shot requests use the `request_uri` interface.

            local res, err = httpc:request_uri("http://192.168.254.241:8080/app.json", {

                method = "GET"

            })

            if not res then

                ngx.log(ngx.ERR, "request failed: ", err)

                return

            end

 

            -- At this point, the entire request / response is complete and the connection

            -- will be closed or back on the connection pool.

 

            -- The `res` table contains the expeected `status`, `headers` and `body` fields.

            local status = res.status

            local length = res.headers["Content-Length"]

            local body   = res.body

            ngx.say(body)

        }

    }

}

• 效果

 

说明

构建好的镜像我已经push dockerhub 了，可以直接使用dalongrong/angie:1.3.1-rocky-luarocks, 目前测试上包查找以及模块功能上与openresty
基本类似，angie 的all-in-one 模式还是挺方便的
