Apache，Tomcat：負載平衡不起作用，無法與 Tomcat 連接

我正在對 2 台伺服器進行負載平衡。它們都在不同的域名上。我已經為他們配置了負載均衡。目前，我無法建立連接。我究竟做錯了什麼？另外，我需要在 server2 上進行什麼配置才能使其正常工作？

錯誤日誌：

Connection refused: AH00957: HTTP: attempt to connect to IP:8090 (IP) failed

阿帕奇 000-default.conf ：

<VirtualHost *:443>
ServerName domain.de
ServerAlias www.domain.de
SSLEngine on
SSLProxyEngine on
SSLProxyVerify none
SSLProxyCheckPeerCN off
SSLProxyCheckPeerName off
SSLProxyCheckPeerExpire off

SSLCertificateKeyFile /etc/letsencrypt/live/domain.de/private.key

您的 HTTPS 連接器在埠 8443 上執行，AJP 在 8009 上執行，而不是在 8090 上。

編輯：

<Proxy balancer://mycluster>
      BalancerMember ajp://SERVER1_IP:8009 route=server1
      BalancerMember ajp://SERVER2_IP:8009 route=server2
</Proxy>
ProxyPass /balancer-manager !
ProxyPass / balancer://mycluster/

# I think you can remove these lines
#ProxyPassReverse / balancer://mycluster/
#ProxyPreserveHost On
