修改 nginx.conf 文件
event{
...
}
stream{
upstream abc {
server 127.0.0.1:3000;
}
server {
listen 3001;
proxy_connect_timeout 1s;
proxy_timeout 5s;
proxy_pass abc;
}
}
http {
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
...
}
主要是新增了 steam 块和 map 部分的代码
修改对应站点的vhost配置文件中 添加
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
server{
....
location / {
proxy_pass http://127.0.0.1:3001;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_connect_timeout 600s;
proxy_read_timeout 600s;
proxy_send_timeout 600s;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
client_max_body_size 30m;
}
....
}
使用 curl测试 websocket
curl --no-buffer -H 'Connection: keep-alive, Upgrade' -H 'Upgrade: websocket' -v -H 'Sec-WebSocket-Version: 13' -H 'Sec-WebSocket-Key: websocket' http://websocket地址 ws | od -t c
原本以为是因为多台socket服务器没有连接到同一个io adapter导致session id互相不认识
我这里是因为2台socket服务器运行导致的，停止一个socket运行服务就解决了。
