Question

我有uWSGI + Apache以及以下apache配置：

RewriteEngine On
RewriteCond %{HTTP:Upgrade} =websocket [NC]
RewriteRule /(.*)           ws://127.0.0.1:3031/$1 [P,L]
RewriteCond %{HTTP:Upgrade} !=websocket [NC]
RewriteRule /(.*)           http://127.0.0.1:3031/$1 [P,L]

ProxyPass / http://127.0.0.1:3031/

现在我想实现粘性会话并让apache为每个worker使用代理平衡器：

<Proxy "balancer://uwsgiworkers">
    BalancerMember "http://127.0.0.1:3031" route=1
    BalancerMember "http://127.0.0.1:3032" route=2
    BalancerMember "http://127.0.0.1:3033" route=3
    ProxySet stickysession=ROUTEID
    ProxySet lbmethod=byrequests
</Proxy> 

RewriteEngine On
RewriteCond %{HTTP:Upgrade} =websocket [NC]
RewriteRule /(.*)           ws://??????/$1 [P,L]
RewriteCond %{HTTP:Upgrade} !=websocket [NC]
RewriteRule /(.*)           http://???????/$1 [P,L]

ProxyPass balancer://uwsgiworkers/

现在问题是如何传递给RewriteRule选定的工作人员网址？因为我需要在WebSockets握手中更改协议。

谢谢！

我最近偶然发现了同样的问题。我不是100％肯定这是正确的选择（感觉很冗长），但这似乎是一个功能选择！

基本上，我创建了两个不同的平衡器组，一个用于HTTP通信，另一个用于WebSocket。我不太确定是否可以在这里省略ProxyPass（似乎balancer://处理了ProxyPass部分），但是在我的环境中似乎工作得很好！

<Proxy "balancer://uwsgiworkers">
    BalancerMember "http://127.0.0.1:3031" route=1
    BalancerMember "http://127.0.0.1:3032" route=2
    BalancerMember "http://127.0.0.1:3033" route=3
    ProxySet stickysession=ROUTEID
    ProxySet lbmethod=byrequests
</Proxy> 

<Proxy "balancer://uwsgiworkersws">
    BalancerMember "ws://127.0.0.1:3031" route=1
    BalancerMember "ws://127.0.0.1:3032" route=2
    BalancerMember "ws://127.0.0.1:3033" route=3
    ProxySet stickysession=ROUTEID
    ProxySet lbmethod=byrequests
</Proxy> 

RewriteEngine On
RewriteCond %{HTTP:Upgrade} =websocket [NC]
RewriteRule /(.*)           balancer://uswsgiworkersws/$1 [P,L]
RewriteCond %{HTTP:Upgrade} !=websocket [NC]
RewriteRule /(.*)           balancer://uswsgiworkers/$1 [P,L]

# I actually think this can be omitted
# it seems that balancer:// handles the ProxyPass
# ProxyPass balancer://uwsgiworkers/
