MySQL数据库本地备份和双机相互备份

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

echo "Start to Backup...";

#ls /var/lib/mysql > /tmp/mydb.all

if [ "$1" != "help" ]; then

for db in `ls $DB_PATH`; do

if_backup="1"

if [ -d $DB_PATH/$db ] ; then

for noBackDB in $NO_BACKUP_DB ; do

if ( test "$db" = "$noBackDB" ); then

#echo -n "...";

if_backup="";

fi

done

if [ $if_backup ]; then

case "$1" in

first)
