Jenkins使用时的问题记录

19 Feb 2024

有个Jenkins挂在服务器上好久没动过了，年后上去看了下发现居然完全挂掉了。

空间不足

还没搞清楚问题前，Jenkins就完全访问不了了，直接在命令行拉起服务，提示

Jenkins failed to create a temporary file in /tmp: java.io.IOException: No space left on device

搜索了下发现是空间不足了，可以参考这里的操作

由于我这边已经连服务都拉不起来了，只能手动删除一些缓存

cd /var/lib/jenkins/jobs/my_awsome_job/
rm -r builds/

然后就可以拉起Jenkins了，按照上面的文章配置了下自动清除，后续观察下有没有问题。

升级失败

出现错误：

参考了这个资料，似乎是密钥变更导致的。直接复制黏贴后就能升级了。
