的本地备份和双机相互备份脚本牛

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..

新华北京11月21日电题：取消药品政府定价适逢其时 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
