 jenkins突然启动报错,一直起不来

已上就是报错信息，看着不明确啊！

回想一下出错场景，当前程序是准备吧一张图片往磁盘上存储，结果挂掉，那么有没有可能是磁盘空间问题？

这么一想，再回头看看报错信息，有戏！

df -h:

[root@172 dev]# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/vda1        40G   40G     0 100% /
devtmpfs        911M     0  911M   0% /dev
tmpfs           920M     0  920M   0% /dev/shm
tmpfs           920M  8.4M  912M   1% /run
tmpfs           920M     0  920M   0% /sys/fs/cgroup
tmpfs           184M     0  184M   0% /run/user/0

发现dev/vda1已经100%了，果然磁盘已经被沾满了

于是果断删除一些文件试试，删除之后df -h :

[root@172 var]# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/vda1        40G   39G     0 100% /
devtmpfs        911M     0  911M   0% /dev
tmpfs           920M     0  920M   0% /dev/shm
tmpfs           920M   20M  900M   3% /run
tmpfs           920M     0  920M   0% /sys/fs/cgroup
tmpfs           184M     0  184M   0% /run/user/0

虽然还是100%，但是内存空出来1G,有戏

接下来启动jenkins试试：

[root@172 var]# service jenkins start
Starting jenkins (via systemctl):                          [  OK  ]

OK，看来之后需要做一些磁盘的定时清理！

ps:   du -sh *  命令可以一步步追查到底是哪个文件夹占领空间大，我这边发现的是/var/lib/docker/volumes占了10G

棒棒哒！
