1：在终端中运行cd命令，提示：
|
e: Write error - write (28 No space left on device) E: Cant mmap an empty file |
2：使用 df -h 查看磁盘空间情况：
|
/dev/xvda1 20G 20G 0G 100% / |
3：继续查看大文件所在目录：#du --max-depth=1 -h /
|
4.0K /opt 9.6M /bin 408K /run 4.0K /srv 4.0K /lib64 0 /sys 9.0M /sbin 34M /boot 224K /home 4.0K /dev du: cannot access ‘/proc/31292/task/31292/fd/4’: No such file or directory du: cannot access ‘/proc/31292/task/31292/fdinfo/4’: No such file or directory du: cannot access ‘/proc/31292/fd/4’: No such file or directory du: cannot access ‘/proc/31292/fdinfo/4’: No such file or directory 0 /proc 284M /lib 80K /tmp 13G /root 4.0K /media 1.3G /mnt 1.2G /usr 16K /lost+found 5.2G /var 6.1M /etc 21G / |
可见 /root下面存在大文件，继续查看：#du --max-depth=1 -h /root
|
8.0K /root/.ssh 13G /root/.pm2 6.0M /root/.forever 17M /root/.npm 4.0K /root/.cache 13G /root |
可见，大文件在.pm2下面，进入此目录进行查看：pm2# ll

发现pm2.log日志文件为13G，将其删除。
