mysqldump_all.sh [first|local|help}
|
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
