Mysqldump-u root-- password=PASSWORD DBNAME >
/ home/bak/sql.penglei.name_$ (date +% F) .sql
Exit 0 input: wq save exit. The script means to first select / home/bak as the site backup directory.
The first step is to delete files under / home/bak for more than 14 days
The second step is to back up the website directory / var/www/html by www.jb51.name_+ date for the file name
Third, export the database for the file name by sql.penglei.name_+ date, and replace PASSWORD and DBNAME with your own root password and database name.
Finally, create a crond script, which can be run automatically at 5 o'clock every morning to create the crond file.
