您需要为第二个Tomcat/TeamCity实例编辑conf\server.xml，以便它使用不同的端口或绑定到不同的网络接口，更改以下端口应为足够:

You need to edit conf\server.xml for the second Tomcat/TeamCity instance so that it uses different ports or binds to different network interfaces, changing the following ports should be enough:

• Server port="8005"
• Connector port="8080"

• Server port="8005"
• Connector port="8080"

两个服务器不能共享同一数据库，因此必须通过

Two servers cannot share the same database, so you must configure them to use different locations via TEAMCITY_DATA_PATH environment variable.
