背景
tengin的nginx_upstream_check_module模块具有心跳检测功能,当发现某个节点不能访问的时候自动切换到另外一个节点,可惜这不是nginx官方自带的模块,需要自己编译
下载nginx
http://nginx.org/en/download.html
下载模块
https://github.com/yaoweibin/nginx_upstream_check_module
进行安装Nginx和编译
tar zxvf nginx-1.20.1
unzip master ### github下载下来就叫master,解压后的文件夹是nginx_upstream_check_module-master
cd nginx-1.20.1
patch -p1 < /usr/local/src/nginx_upstream_check_module-master/check_1.20.1+.patch #这步很重要,打补丁
./configure --prefix=/usr/local/nginx --add-module=../nginx_upstream_check_module-master
make
make install
编辑配置文件
vi /usr/local/nginx/conf/nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
upstream cluster {
server 10.10.10.100:80;
server 10.10.10.110:5040;
check interval=3000 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;
location / {
root html;
index index.html index.htm;
proxy_pass http://cluster;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
location /status {
check_status;
access_log off;
}
}
}
启动并验证
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
