JIRA启动报错：The jira.home directory '/opt/jira_home' is already locked. JIRA startup failed, JIRA has been locked.

    启动JIRA时候，日志出现如下错误：

The jira.home directory '/opt/jira_home' is already locked.     JIRA startup failed, JIRA has been locked.

    出错原因是'/opt/jira_home' 下有一个 .jira-home.lock文件，删除重新启动就好了。.jira-home.lock文件是为了防止在一台机器上跑多个JIRA站点，并且又设置了同一个jira.home的情況
