Insufficient space in linux

Reasons for insufficient Linux space:

1. The disk is full

2. The memory is full

Solution to insufficient disk space:

1. First determine whether there is insufficient disk space.

Enter the command: df –h View disk information

Obviously: the 40G capacity under the mount point /dev/xvda1 under Filesystem has been exhausted. At this time, the easiest way is to find large and useless files and To delete, the first choice is the log file.

2. Enter the command: du -h --max-depth=1 Find which folder in the current directory takes up the most space

3. Enter the logs folder

Enter the command: ls –lhS Display the files in order from large to small

Enter Command: > ./catalina.out Complete the cleanup.

Note: If the process is in use when clearing the log, either an error will be reported when using rm -f to delete, or the disk will still be full even if it is deleted, so use the command to clear the log file contents. Better than deleting this file.
