MySQL數(shù)據(jù)庫本地備份和雙機(jī)相互備份 時(shí)間：2015/6/28來源：IT貓撲網(wǎng)作者：網(wǎng)管聯(lián)盟我要評(píng)論(0)

mysql的本地備份和雙機(jī)相互備份腳本：

首先，我們需要修改腳本進(jìn)行必要的配置,然后以root用戶執(zhí)行。

◆1. 第一執(zhí)行遠(yuǎn)程備份時(shí)先用 first參數(shù).

◆2. 本地備份用local參數(shù)

◆3. 遠(yuǎn)程備份不用參數(shù)<注意1>

注意:

需要在另一主機(jī)上的MySQL用戶里添加用戶。

需要配置的地方:

# define host and mysql password

REMOTE_HOST="" #遠(yuǎn)程主機(jī)名或IP

REMOTE_PASSWORD="" #遠(yuǎn)程主機(jī)的mysql中的root@本地主機(jī) 密碼.

# define database path

DB_PATH="/var/lib/mysql" #本地mysql數(shù)據(jù)庫路徑

LOCAL_PASSWORD="" #本地mysql root用戶密碼

DB_BACKUP_PATH="/root/db_bk" #本地備份時(shí)數(shù)據(jù)保存的路徑

NO_BACKUP_DB="" 設(shè)置本地?cái)?shù)據(jù)庫中不想備份的數(shù)據(jù)庫名,用空格隔開
