使用nginx为udp服务负载均衡
对nginx的最低版本要求是? 1.9.13 The ngx_stream_proxy_module module (1.9.0) allows proxying data streams over TCP, UDP (1.9.13), and UNIX-domain sockets. 简单的配置是什么样? 例如监听本地53的udp端口,然后转发到192.168.136.130和192.168.136.131的53端口 注意事项 stream是顶层的配置,不能包含在http模块里面 proxy_responses很重要,如果你的udp服务只接受udp消息,并不发送udp消息,那么务必将proxy_responses的值设置为0 stream { upstream dns_upstreams { server 192.168.136.130:53; server 192.168.136.131:53; } server { listen 53 udp; proxy_pass dns_upstreams; proxy_timeout 1s; proxy_responses 0; error_log logs/dns.log; } } | Syntax: | proxy_responses number; Default: — Context: stream, server | This directive appeared in version 1.9.13. Sets the number of datagrams expected from the proxied server in response to a client datagram if the UDP protocol is used. The number serves as a hint for session termination. By default, the number of datagrams is not limited. If zero value is specified, no response is expected. However, if a response is received and the session is still not finished, the response will be handled. ...
