前面有一篇文章记录nginx负载均衡后端检查,链接为 http://www.info110.com/Linux/2019-04/158352.htm
但是只包含http健康检查不包含tcp下面安装nginx可以实现http及tcp健康检查
安装
git clone https://github.com/nginx/nginx.git
git clone https://github.com/zhouchangxun/ngx_healthcheck_module.git
cd nginx/;
git checkout branches/stable-1.12
git apply ../ngx_healthcheck_module/nginx_healthcheck_for_nginx_1.12+.patch
./auto/configure –with-stream –add-module=../ngx_healthcheck_module/
make && make install
git下载nginx及健康检查模板安装nginx
配置http的upstream配置样式如下
upstream www.xxx.net{
server 172.16.90.232:81;
check interval=3000 rise=2 fall=5 timeout=5000 type=http;
check_http_send “GET / HTTP/1.0rnrn”;
check_http_expect_alive http_2xx http_3xx;
}
配置tcp的upstream的配置样式如下
upstream device5000{
server 172.16.90.52:5000;
server 172.16.90.53:5000;
check interval=3000 rise=2 fall=5 timeout=5000 default_down=true type=tcp;
}
在主配置文件新加一个location
location /upstream_status{
healthcheck_status html;
}
Web页面访问
http://ip/upstream_status
页面显示如下
