基于innobackupex的mysql备份脚本

mysql_backup.sh程序安装说明

1、安装mysqlbackup程序

上传mysqlbackup到服务器/tmp目录

cd /tmp

unzip mysqlbackup.zip

cp /tmp/mysqlbackup/* /opt/mysql/product/5.1/bin

mkdir -p /opt/MySqlBackUp/bin

mkdir -p /opt/MySqlBackUp/data

mkdir -p /opt/MySqlBackUp/logs

mkdir -p /opt/MySqlBackUp/temp

ln -s /opt/mysql/product/5.1/bin/innobackupex /opt/MySqlBackUp/bin/innobackupex

对innobackupex进行授权

cd /opt/mysql/product/5.1/bin/

chmod +x innobackupex*

chmod +x xtrabackup*

chmod +x tar4ibd

cp /tmp/mysqlbackup/mysql_backup.sh /opt/MySqlBackUp/bin/

chmod 775 /opt/MySqlBackUp/bin/mysql_backup.sh

2、修改mysql_backup.sh中的相关数据

dbuser

dbpasswd

mail

dumpdb

3、配置mysql环境变量到root中

export MYSQL_BASE=/opt/mysql

export BASEDIR=$MYSQL_BASE/product/5.1

export DATADIR=$MYSQL_BASE/mysqldata

export LD_LIBRARY_PATH=$BASEDIR/lib:/lib:/usr/lib:/usr/local/lib

export TMPDIR=/tmp

export PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin

export PATH=${PATH}:$BASEDIR/bin:$MYSQL_BASE:$BASEDIR:$LD_LIBRARY_PATH

添加到/root/.bash_profile文件中

4、测试备份

cd /opt/MySqlBackUp/bin

./mysql_backup.sh

5、查看备份是否成功

cat /opt/MySqlBackUp/logs/result.log

如果提示备份成功，则表示程序安装成功，可能不熟到crontab中

6、部署crontab

0 1 * * * (cd /opt/MySqlBackUp/bin;sh ./mysql_backup.sh)

说明：参数配置，均是基于按照mysql安装路径配置
