   先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用户用添加用户..

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
