Linux系統(tǒng)下進行定時任務(wù)操作時,突然提示bash: crontab: command not found,出現(xiàn)該問題多半是未安裝crontab所導(dǎo)致,只需在Linux系統(tǒng)下安裝crontab即可解決問題。
crontab安裝步驟:
1. 確認crontab是否安裝:
執(zhí)行 crontab 命令如果報 command not found,就表明沒有安裝
2. 安裝 crontab
安裝過程如下
[root@10vps ~]# crontab -e
-bash: crontab: command not found
。踨oot@10vps ~]# yum install -y vixie-cron
