参考

• cron自動実行

手順

1. バッチを配置

   sudo mv /var/local/backup_table_test.sh backup /usr/local/bin/
   ※permission は644

1. add permission

   sudo chmod 744 /usr/local/bin/backup_table_test.sh

1. confirm permission

   ll /usr/local/bin/backup_table_test.sh

-rwxr--r-- 1 root staff 754 10月  4 15:36 /usr/local/bin/backup_table_test.sh*

1. create log directory

   ※デフォルトは/var/log/syslog (ubuntu)
   sudo mkdir /var/log/cron

1. create backup directory

   sudo mkdir /usr/local/bin/backup

1. cron setting

   sudo にしないとrootで設定しないので権限エラーになる
   sudo crontab -e
