nginx-nginx_upstream_check_module主动健康检查模块
nginx版本nginx-1.20.2.tar.gz
wget https://github.com/yaoweibin/nginx_upstream_check_module/archive/refs/heads/master.zip
进入到nginx根目录
cd /datasdb/nginx-1.20.2/
yum install - patch
打补丁
patch -p1 < ../nginx_upstream_check_module-master/check_1.20.1+.patch
./configure --with-http_stub_status_module --add-module=/datasdb/nginx_upstream_check_module-master
注:这里我还用到了http_stub_status_module模块,所以一起打包编译
make 执行无损升级方案即可
conf配置:
upstream local_tomcat {
server 172.16.200.34:9101 max_fails=2 fail_timeout=1s;
server 172.16.200.39:9101 max_fails=2 fail_timeout=1s;
check interval=3000 rise=2 fall=3 timeout=1000 type=http;
check_http_send "GET /index.jsp HTTP/1.0
";
check_http_expect_alive http_2xx http_3xx;
}
location /tomcat_status {
check_status;
access_log off;
}
最终效果:
