MySQL的本地備份和雙機相互備份腳本

先修改腳本進行必要的配置,然后以root用戶執行. 1. 第一執行遠程備份時先用 first參數. 2. 本地備份用local參數 3. 遠程備份不用參數注意1 注意:需要在另一主機上的Mysql用戶用添加用戶.. 需要配置的地方: # define host and mysql password REMOTE_HOST=""

先修改腳本進行必要的配置,然后以root用戶執行.

1. 第一執行遠程備份時先用 first參數.
2. 本地備份用local參數
3. 遠程備份不用參數<注意1>
注意:需要在另一主機上的Mysql用戶用添加用戶..
需要配置的地方:

# define host and mysql password
REMOTE_HOST="" #遠程主機名或IP
REMOTE_PASSWORD="" #遠程主機的mysql中的root@本地主機 密碼.
# define database path
DB_PATH="/var/lib/mysql" #本地mysql數據庫路徑
LOCAL_PASSWORD="" #本地mysql root用戶密碼
DB_BACKUP_PATH="/root/db_bk" #本地備份時數據保存的路徑
NO_BACKUP_DB="" 設置本地數據庫中不想備份的數據庫名,用空格隔開
直接下載
