nginx error.log报错信息如下： 2018/01/21 19:16:55 [error] 31764#0: upsync_timeout: timed out reading upsync_server: 10.10.75.150:2379

求解决方案?

0、环境： nginx-1.12.2, etcd: 3.2.1

1、场景： k8s的master ssl 6433端口代理

2、配置配置文件如下： upstream k8s_master_apiserver { hash $remote_addr consistent;

server 10.10.75.150:6443 max_fails=3 fail_timeout=30s weight=2;

# server 10.10.75.151:6443 max_fails=3 fail_timeout=30s weight=2;
# server 10.10.75.153:6443 max_fails=3 fail_timeout=30s `weight=2;`
upsync 10.10.75.150:2379/v2/keys/upstreams/k8s_master_apiserver upsync_timeout=6m upsync_interval=500ms upsync_type=etcd strong_dependency=off;
upsync_dump_path /usr/local/nginx/conf/tcp_udp_vhosts/A-tcp-udp-upstream.conf;
# include /usr/local/nginx/conf/tcp_udp_vhosts/A-tcp-udp-upstream.conf;

}

server { listen 6443; access_log /usr/local/nginx/logs/k8s.master.6443-access.log proxy; error_log /usr/local/nginx/logs/k8s.master.6443-error.log; proxy_connect_timeout 30s; proxy_timeout 30s; proxy_pass k8s_master_apiserver; proxy_next_upstream on; }

3、配置测试，提示no servers错误： /usr/local/nginx/sbin/nginx -t nginx: [emerg] no servers are inside upstream in /usr/local/nginx-1.12.2/conf/tcp_udp_vhosts/k8s_master_proxy.conf:10 nginx: configuration file /usr/local/nginx-1.12.2/conf/nginx.conf test failed

4、upsync_dump_path对应的文件为空 total 8.0K drwx------ 2 root root 66 Jan 21 16:16 . drwx------ 4 root root 4.0K Jan 21 15:38 .. -rw-r--rw- 1 root root 0 Jan 21 16:05 A-tcp-udp-upstream.conf -rw------- 1 root root 868 Jan 21 16:16 k8s_master_proxy.conf

5、etcd集群的设置如下： curl -s http://10.10.75.150:2379/v2/keys/upstreams/k8s_master_apiserver | python -m json.tool { "action": "get", "node": { "createdIndex": 53, "dir": true, "key": "/upstreams/k8s_master_apiserver", "modifiedIndex": 53, "nodes": [ { "createdIndex": 53, "key": "/upstreams/k8s_master_apiserver/10.10.75.153:6443", "modifiedIndex": 53, "value": "{\"weight\":1, \"max_fails\":2, \"fail_timeout\":10}" }, { "createdIndex": 54, "key": "/upstreams/k8s_master_apiserver/10.10.75.150:6443", "modifiedIndex": 54, "value": "{\"weight\":1, \"max_fails\":2, \"fail_timeout\":10}" }, { "createdIndex": 55, "key": "/upstreams/k8s_master_apiserver/10.10.75.151:6443", "modifiedIndex": 55, "value": "{\"weight\":1, \"max_fails\":2, \"fail_timeout\":10}" } ] } }

采用etcd, 然后按配置搞完出现如下错误，求解？ #27

server 10.10.75.150:6443 max_fails=3 fail_timeout=30s weight=2;
