1、需要修改的文件：jira-application.properties
cat jira-application.properties
# Do not modify this file unless instructed. It is here to store the location of the JIRA home directory only and is typically written to by the installer.
#jira.home = /var/atlassian/application-data/jira （数据备份初始化路径）
jira.home = /mnt/jira （修改后的路径）
(1)修改之前记得备份cp jira-application.properties jira-application.properties.bak
2、可以用如下命令查找jira-application.properties
find / -name jira-application.properties
3、修改路径后，不要忘记把原路径jira.home = /var/atlassian/application-data/jira 数据完整复制到jira.home = /mnt/jira 下，新目录下文件属性不要忘记修改了：
chmod -Rf jira:jira jira/
4、重启jira即可。
