问题upstream ops { #ip_hash; server 5000.ali-bj.cloud.net:10080 weight=2 max_fails=1 fail_timeout=2; server 5000.ali-sh.cloud.net:10080 weight=1 max_fails=1 fail_timeout=2; #server 192.168.0.4:5000 max_fails=1 fail_timeout=2; #server 127.0.0.1:12309; #server 127.0.0.1:12310; #server 127.0.0.1:10080 ;}----#web.conf主要配置 location / {add_header Version v3.1.5.3;add_header Os QingDao.aliyun.Debian8;proxy_set_header X-Via QingDao.Aliyun;proxy_set_header Connection '';proxy_set_header Host $http_host;proxy_set_header X-Real_IP$remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_pass http://ops;proxy_cache opscache;proxy_cache_valid 200 302 5m;proxy_cache_valid 301 1h;proxy_cache_valid any 1m; }
说明：
5000.ali-bj.cloud.net／5000.ali-sh.cloud.net 域名都是解析到同一个ip(192.168.1.124)上的
访问域名502：
2017/04/03 11:26:14 [error] 408#408: *1 upstream prematurely closed connection while reading response header from upstream, client: 192.168.1.105, server: dev.cloud.net, request: 'GET / HTTP/1.1', upstream: 'http://192.168.1.124:10080/', host: 'dev.cloud.net'疑问？
nginx upstream可以根据域名进行负载均衡吗？设置了Host $http_host还是一样的
问题解答
回答1：很明显nginx是支持虚拟主机的！然后不同的虚拟主机定义不同的upstream不就行了！
