openresty ngx_http_upstream_check_module 模块安装
本文主要是介绍openresty ngx_http_upstream_check_module 模块安装，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
实际上测试了tengine以及其他的ngx_http_upstream_check_module发现都不好使，反而发现ngx_healthcheck_module 值得使用
构建
基于docker，复用了openresty 官方的dockerfile 构建模式，核心流程如下
clone ngx_healthcheck_module 模块，patch 布丁到openresty，执行构建
- dockerfile
集成了部分tengine的模块

STOPSIGNAL SIGQUIT
参考使用
- docker-compose
version: '3'
services:
app:
image: dalongrong/openresty-tengine:latest
volumes:
- "./nginx.conf:/usr/local/openresty/nginx/conf/nginx.conf"
privileged: true
cap_add:
- ALL
ports:
- "80:80"
app2:
image: dalongrong/openresty-tengine:latest
app3:
image: dalongrong/openresty-tengine:latest
- nginx.conf
worker_processes 1;
user root;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
gzip on;
upstream cluster1 {
# simple round-robin
server app2:80;
server app3:80;
check interval=1000 rise=2 fall=5 timeout=1000 type=http;
check_http_send "HEAD / HTTP/1.0\r\n\r\n";
check_http_expect_alive http_2xx http_3xx;
}
server {
listen 80;
server_name localhost;
charset utf-8;
default_type text/html;
location / {
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_body_buffer_size 10M;
client_max_body_size 10G;
proxy_buffers 1024 4k;
proxy_read_timeout 300;
proxy_connect_timeout 80;
proxy_pass http://cluster1;
}
location /status {
healthcheck_status;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
- 效果
当然直接prometheus metrics 可以直接使用
说明
我已经构建好了一个镜像，可以直接使用dalongrong/openresty-tengine:latest，还是得吐槽下tengine了问题不少，而且基本不维护了（好像今年又要开始维护了。。。。）,如果为了方便监控，推荐也集成上nginx 的vts模块,真得好好学学nginx 模块开发了，不然解决问题就有点费事了
