借住Nginx实现负载均衡和灰度发布的功能

Nginx实现灰度发布的功能

1. 对URL进行单独的过滤发布

upstream A {
ip_hash;
server 10.0.XX.XX:9000;
server 10.0.XX.XX:9010;
}
upstream B {
#server 10.0.5.76:9000;
server 10.0.5.76:9010;
}
server {
listen       80;
server_name  www.xxxx.com;
#charset koi8-r;
access_log  logs/host.xxx.log  main;

location / {
proxy_pass   http://A; proxy_set_header  Host            $host;
proxy_set_header  X-Real-IP        $remote_addr;
proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;
index  index.html index.htm;
}
location ~ /print/xxxInfo {
proxy_pass   http://B; proxy_set_header  Host            $host;
proxy_set_header  X-Real-IP        $remote_addr;
proxy_set_header  X-Forwarded-For                    $proxy_add_x_forwarded_for;
proxy_read_timeout 150;
}
#location ~ /mps/xxxInfo {
#			return 500;
#		}
##开启后直接封掉某个请求。
#location ~ /mps/xxxB {
#			return 500;
#}
}

2. 针对IP地址进行过滤

如果是内部IP，则反向代理到hilinux_02(预发布环境)；如果不是则反向代理到hilinux_01(生产环境)。

upstream hilinux_01 {
server 192.168.1.100:8080 max_fails=1 fail_timeout=60;
}

upstream hilinux_02 {
server 192.168.1.200:8080 max_fails=1 fail_timeout=60;
}

upstream default {
server 192.168.1.100:8080 max_fails=1 fail_timeout=60;
}

server {
listen 80;
server_name  www.hi-linux.com;
access_log  logs/www.hi-linux.com.log  main;

set $group default;
if ($remote_addr ~ "211.118.119.11") {
set $group hilinux_02;
}

location / {
proxy_pass http://$group; proxy_set_header   Host             $host;
proxy_set_header   X-Real-IP        $remote_addr;
proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
index  index.html index.htm;
}
}
