This article will explain in detail how to implement full and incremental backup scripts in mysqldump. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

#! / bin/bash

#

# mysql full backup script. It is recommended to run it on slave slave library and enable log_slave_updates=1.

Backupdir=/backup

DateDIR= `date +% Ymuri% mmury% d`

LogsindexPath=/usr/local/mysql/logs/ray-bin.index

If [!-d $backupdir]; then

Mkdir-p $backupdir

Fi

Cd ${backupdir}

If [!-d $dateDIR]; then

Mkdir-p $dateDIR

Fi

For i in `mysql-uroot-p123456-e "show databases" 2 > & 1 | grep-v-E "Database | Warning" `

Do

Mysqldump-uroot-p123456-- default-character-set=utf8-Q-- flush-privileges-- single-transaction-- master-data=1-- flush-logs-- routines-- triggers-- events-- hex-blob-E-R-B testdb | gzip > ${backupdir} / ${dateDIR} / mysql_back_$ {I} _ ${dateDIR} .sql.gz

Done

Binlog_rm= `tail-n 1 ${logsindexPath} | awk-F'/'{print $NF}'`

Mysql-uroot-p123456-e "purge binary logs to'${binlog_rm}'"

#! / bin/bash

# mysql incremental backup script, it is recommended to run it on slave slave server and enable log_slave_updates=1

Backupdir=/backup

DateDIR= `date +% Ymuri% mmury% d`

LogsIndexPath=/usr/local/mysql/logs/ray-bin.index

Mysqladmin-uroot-p123456 flush-logs

Binlog_cp= `head-n-1 ${logsIndexPath} `

For i in ${binlog_cp}

Do

Mysql-uroot-p123456-e "\! cp-p ${I} ${backupdir} / ${dateDIR} /"

Done

Binlog_rm= `tail-n 1 ${logsIndexPath} | awk-F'/'{print $NF}'`

Mysql-uroot-p123456-e "purge binary logs to'${binlog_rm}'"
