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 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 ;
events {
worker_connections ;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout ;
listen ;
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 ;
events {
worker_connections ;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout ;
listen ;
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！
