原因

Below are the cause for the Issue

1. Proper permission is not available to Bamboo user to <bamboo-home> and <bamboo-install> folders.
2. Bamboo is not able to read the bamboo.cfg.xml file (or the file is corrupted).

ソリューション

Solution outlined will cover both the causes explained above.

Solution 1 : To provide proper permission to folders

• The first step is to make sure proper permission is provided to bamboo folders and files are owned by user which is running Bamboo. Please run the below command

  chown -R <user_name> <bamboo-home>
  chown -R <user_name> <bamboo-install>

    where <user_name> is the user_id you're using to start the service.
   Please include the -R parameter as it is important to make sure the ownership to all files and subfolders will also be adjusted.

Solution 2 : To regenerate bamboo.cfg.xml file.

• Rename the bamboo.cfg.xml file with the below command

  mv bamboo.cfg.xml bamboo.cfg.xml_bkp

Below steps would be common for both solution 1 and solution 2 defined above. 

• Restart Bamboo and verify if the bamboo.cfg.xml file was created with the correct permission (bamboo user).
• Move forward with the installation.
