今天早上想打開dapeng-cli監(jiān)控一下線上服務(wù), 登錄服務(wù)器后, 沒想到居然打不開:
[logview@monitor-elk dapeng-cli]$ ./dapengCli

no jansi in java.library.path, 這可是從來沒出現(xiàn)過的錯誤, 通過各種花式搜索, 找到的都是不著邊際的答案.
然后過了10來分鐘, 不少業(yè)務(wù)團(tuán)隊過來抱怨定時任務(wù)失效. 我們的定時任務(wù)也是在上面的服務(wù)器中通過crontab來觸發(fā)定時任務(wù)的.
這時候, 發(fā)現(xiàn)定時任務(wù)只能查看不能修改, 現(xiàn)狀如下:
[root@monitor-elk ~]# crontab -l
*/1 * * * * sh /data/scripts/synccp.sh /data
05 0 * * * sh /data/scripts/serviceMonitor.sh /data/logs/
[root@monitor-elk ~]# crontab -e
/tmp/crontab.nUAdxv: 沒有那個文件或目錄
然后一番折騰, 運(yùn)維大哥發(fā)現(xiàn)是/tmp目錄給刪除了(早上有人改了某個腳本, 該腳本會定時刪除/tmp目錄). 重建/tmp目錄后, 一切回復(fù)正常(當(dāng)然也要修正那個錯誤的腳本).
