For example, an enterprise MySQL database cloud server needs to design a script.
This article mainly introduces an example of an enterprise MySQL database cloud server needs to design a script, which involves things, learned from the theoretical knowledge, there are many books and literature for your reference, in terms of practical significance, accumulated years of practical experience can be shared with you.
Background: an enterprise MySQL database cloud server (innodb engine) needs to be fully implemented at zero o'clock on Saturday night, and incremental backups are used from Monday to Friday and Sunday. A script needs to be designed.
The script I designed is as follows. Please post it and welcome everyone to beat the brick.
#! / bin/bash
[- f / tmp/lock] & & exit 2
Touch / tmp/lock
[- S / data/3306/mysql.sock] | | exit 1
Today=$ (date +% w)
Yesterday=$ (date +% w-d-1day)
Fullback () {
Rm-fr / backup/bak$today/ & &\
/ usr/bin/innobackupex-user=root-password=123-socket=/data/3306/mysql.sock-no-timestamp-use-memory=32M / backup/bak$today
}
Increback () {
Rm-fr / backup/bak$today/ & &\
/ usr/bin/innobackupex-user=root-password=123-incremental--socket=/data/3306/mysql.sock-incremental-basedir=/backup/bak$yesterday-no-timestamp-use-memory=32M / backup/bak$today
}
If [$today-eq 6]
Then
Fullback
Else
Increback
Fi
Rm-f / tmp/lock
Use tools: xtrabackup, physical backup is fast and efficient
Scheduled tasks use crontab
00 * / bin/bash / server/scripts/bakup_sql.sh > / dev/null 2 > & 1
