如下配置nginx
map$http_upgrade $connection_upgrade {
default upgrade;
''close;
}
upstream websocket {
server 128.190. 82.105: 8888;
}
server {
listen8888;
server_name proxy.hello.com;
ssl on;
ssl_certificate /etc/nginx/ssl/hello.com_bundle.crt;
ssl_certificate_key /etc/nginx/ssl/hello.com.key;
ssl_session_timeout 20m;
ssl_verify_client off;
location / {
proxy_pass http: //websocket;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
}
}128.190.82.105:8888是真正的服务端地址，nginx所在域名是proxy.hello.com，代理的端口号是8888，所以前端访问的时候这样配置：
WEBSOCKET_URL: 'wss://proxy.hello.com:8888',
检查nginx.conf正确性：
nginx-t
重新加载配置文件：
nginx-s reload
