使用lua-resty-repl 调试openresty
lua-resty-repl 是一个方便的openresty 包,我们可以用来方便的调试openresty
以下是一个基于容器运行的一个试用
环境准备
- dockerfile
主要是安装模块以及一个supervisord(方便运行的,使用此接管1号进程)
FROM openresty/openresty:alpine-fat
RUN /bin/sed -i 's,
RUN apk update && apk add git
COPY --from=ochinchina/supervisord:latest /usr/local/bin/supervisord /usr/local/bin/supervisord
RUN /usr/local/openresty/luajit/bin/luarocks install lua-resty-repl
ENTRYPOINT [ "/usr/local/bin/supervisord" ]
- docker-compose 文件
version: "3"
services:
api:
build: ./
image: dalongrong/openresty:lua-resty-repl
volumes:
- "./nginx.conf:/usr/local/openresty/nginx/conf/nginx.conf"
- "./supervisor.conf:/etc/supervisor.conf"
ports:
- "80:80"
- "9001:9001"
- supervisor 配置
可以不用
[inet_http_server]
port = :9001
- nginx 配置
nginx.conf
master_process off;
worker_processes 1;
error_log stderr notice;
daemon off;
events {
worker_connections 1024;
}
http {
server {
listen 80;
lua_code_cache off;
include mime.types;
default_type application/octet-stream;
gzip on;
resolver 127.0.0.11 ipv6=off;
real_ip_header X-Forwarded-For;
real_ip_recursive on;
location / {
content_by_lua_block {
require('resty.repl').start()
}
}
}
}
试用
- 构建镜像
docker-compose build
- 启动
docker-compose up -d
- 启动openresty
进入容器
docker-compose exec api sh
openresty -c /usr/local/openresty/nginx/conf/nginx.conf
- 发送请求
- 效果
- 执行调试命令
ngx.req.get_uri_args()
效果
说明
lua-resty-repl 是一个不错的openresty 调试工具,可以帮助我们调试一些问题,相比使用ngx.say 以及ngx.log 方便了好了很多
