MySQL数据库本地备份和双机相互备份脚本

MySQL的本地备份和双机相互备份脚本：

首先，我们需要修改脚本进行必要的配置,然后以root用户执行。

◆1. 第一执行远程备份时先用 first参数.

◆2. 本地备份用local参数

◆3. 远程备份不用参数<注意1>

注意:

需要在另一主机上的MySQL用户里添加用户。

需要配置的地方:

# define host and mysql password

REMOTE_HOST='' #远程主机名或IP

REMOTE_PASSWORD='' #远程主机的mysql中的root@本地主机 密码.

# define database path

DB_PATH='/var/lib/mysql' #本地mysql数据库路径

LOCAL_PASSWORD='' #本地mysql root用户密码

DB_BACKUP_PATH='/root/db_bk' #本地备份时数据保存的路径

NO_BACKUP_DB='' 设置本地数据库中不想备份的数据库名,用空格隔开

直接下载

#!/bin/sh

# mysqldump_all.sh

# this scripts is used to backup MySQL database bettwen tow MySQL SERVER!

# define host and mysql password

REMOTE_HOST=''

REMOTE_PASSWORD=''

# define database path

DB_PATH='/var/lib/mysql'

LOCAL_PASSWORD=''

DB_BACKUP_PATH='/root/db_bk'

# define which database no back up, write db anme escap whit space!

# example;

# NO_BACKUP_DB='yns test ps_note'

# this said that if db name is 'yns' or 'test' or 'ps_note', then not backup them!

NO_BACKUP_DB=''

# get the database name and process one by one
