jira6.3.6+confluence5.4.4整合成功，但启动报错，求教

[sinat_27426733]

jira6.3.6和confluence5.4.4已经整合成功了，但启动confluence时后台报错
1、我使用start-confluence.sh启动时，页面无法访问
控制台打印内容如下：
To run Confluence in the foreground, start the server with start-confluence.sh -fg
executing as current user
If you encounter issues starting up Confluence Standalone, please see the Installation guide at http://confluence.atlassian.com/display/DOC/Confluence+Installation+Guide

Server startup logs are located in /Users/alex/confluence/atlassian-confluence-5.4.4/logs/catalina.out

Existing PID file found during start.
Tomcat appears to still be running with PID 12338. Start aborted.

2、我使用start-confluence.sh -fg启动时，页面可以访问，但控制台报警告
控制台打印内容如下：
Thu Feb 25 20:41:32 CST 2016 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

求教大神，我是哪里设置出了问题？

第一个问题：先停止服务，用ps -ef | grep java，查看是否确定停止，删除/Users/alex/confluence/atlassian-confluence-5.4.4/work/catalina.pid，重新启动即可。
