  2. 新增設定檔 /etc/httpd/conf.d/proxy_ajp.conf

  3. 設定內容

    <VirtualHost ServerIP:80>
  ServerName ServerIP

  ProxyRequests Off
  ProxyPass /ProjName ajp://localhost:8009/ProjName
  ProxyPassReverse /ProjName ajp://localhost:8009/ProjName
  ProxyPass / http://localhost:3000/
  ProxyPassReverse / http://localhost:3000/
</VirtualHost>

  4. 檢查設定內容的語法是否正確，若無錯誤重開服務

    apachectl configtest
systemctl restart httpd

    setsebool -P httpd_can_network_connect 1
