Confluence 和 synchrony 无法启动
Confluence and synchrony can't start up
问题
当我尝试启动 Confluence 时，我总是得到这个异常：
30-Aug-2017 08:44:03.053 SEVERE [main] org.apache.catalina.core.StandardServer.await StandardServer.await: create[localhost:8091]:
java.net.BindException: Address already in use (Bind failed)
这是日志和 server.xml:
我的confluence版本：confluence-6.3.1
到目前为止我注意到了什么
当我启动 confluence 时，它会生成一个进程（在 08:41 AM）

哪个使用8090端口
netstat -nap |grep :::80
tcp6 0 0 :::8090 :::* LISTEN 5430/java
然后它产生另一个进程（在 08:43 AM）

哪个使用8091端口
tcp6 0 0 :::8090 :::* LISTEN 5430/java
tcp6 0 0 :::8091 :::* LISTEN 5756/java
几分钟后它无法启动。如果我终止同步进程（第二个），汇合会正确启动，但我无法编辑文档，因为我在 synchrony-proxy/heartbeat url.[=19 上收到 502 错误=]
那我该怎么办？我可以把同步放到另一个端口吗？或者同步应该更快地启动并释放端口？预期的行为是什么？
同步端口可以通过设置系统更改属性:
Synchrony runs on port 8091 by default. If this port is already in use
by another application on your server you can use the the
synchrony.port system property to change it to an available port.
此外：
Multiple Synchrony processes If you see an error immediatley in the
editor, but Confluence reports that Synchrony is running, check to
make sure that you only have one Synchrony process running. If you do
have multiple Synchrony processes running, stop Confluence, kill the
additional Synchrony processes and then restart Confluence. You can
avoid this problem by always using stop-confluence.sh /
stop-confluence.bat to stop Confluence, rather than simply closing the
Tomcat window.
