在confluence中出现Handshake failed due to invalid Upgrade header: null

在confluence中出现Handshake failed due to invalid Upgrade header: null

昨天晚上同事说confluence写完日志保存不了，然后我登陆confluence写日志进行保存，竟然真的保存不了，报错信息如下：

与服务器失去连接，请联系confluence管理员。

当时就进行排查，首先找到confluence的日志

#cd /opt/atlassian/confluence/logs
#tail -f -n 100 catalina.out

可以看到确实是confluence日志里有报错，首先看到http-nio-18090-exec-6，当时就想到我在阿里云上面做了域名解析，然后在本地服务器上做了nginx的代理转发，查看nginx的配置文件：

#cd /application/nginx/conf
#vim nginx.conf
worker_processes  1;
        events {
                worker_connections  1024;
        }
        http {
              include       mime.types;
              default_type  application/octet-stream;
              sendfile        on;
              keepalive_timeout  65;
    listen 80;
    server_name wiki.gong-hui.com;
    location / {
        proxy_redirect off;
        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://192.168.3.175:18090;
               }
  }

接着在网上搜索confluence日志文件中的报错信息，发现需要在nginx配置文件location中加入两行信息：

proxy_set_header Upgrade $http_upgrade;

proxy_set_header Connection  "upgrade";

worker_processes  1;
        events {
                worker_connections  1024;
        }
        http {
              include       mime.types;
              default_type  application/octet-stream;
              sendfile        on;
              keepalive_timeout  65;
    listen 80;
    server_name wiki.gong-hui.com;
    location / {
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection  "upgrade";
        proxy_redirect off;
        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://192.168.3.175:18090;
               }
  }

再次到confluence中进行日志提交，成功，完美解决！
