[linux] 리눅스(CentOS/우분투)에서 CRONTAB 설치 방법

[linux] 리눅스(CentOS/우분투)에서 CRONTAB 설치 방법

 

 

가장 대표적인 리눅스 배포판인 CentOS 및 우분투에서 CRONTAB 설치하는 방법을 알아 보겠습니다.

 

저도 가끔 다시 설치하려고 하면 정확한 패키지명을 cron이라고만 생각해서 설치를 시도해서~~

매번 검색하는 번거로움을 줄이고자 정리 해봅니다.

 

CentOS에서 CRONTAB 설치하기

yum -y install cronie명령어를 실행 합니다.

bash-4.2# yum -y install cronie

 

이 명령어를 실행하면 아래와 같이 CRONTAB설치가 시작됩니다.

Complete!
bash-4.2#

 

그 다음 service crond start로 크론 서비스를 실행 해 주시면 됩니다.

bash-4.2# service crond start

 

마지막으로 서버가 재시작 될 때, 자동으로 crond를 실행하기 위해서 /sbin/chkconfig --levels 235 crond on명령어로 서비스에 등록 해 줍니다.

bash-4.2# /sbin/chkconfig --levels 235 crond on

 

Ubuntu에서 CRONTAB 설치하기

yum -y install cron명령어를 실행 합니다.

bash-4.2# apt-get install -y cron
