mysql如何对数据库进行恢复
1、备份文件中只包含表的备份,不包含库的语句时,导入时必须指定库名,目标库必须存在。
可以从备份文件mysql-user.sql引入test库。
代码语言:javascript复制[root@localhost ~]# mysql -u root -p test < mysql-user.sql
Enter password:
[root@localhost ~]# mysql -u root -p
Enter password:

mysql> show tables;

| user |
----------------
1 row in set (0.00 sec)
mysql>
2、如果备份文件包含完整的库信息,则在进行导入操作时不需要指定库名,可以从备份文件auth.sql恢复auth库。
代码语言:javascript复制[root@localhost ~]# cd /usr/local/mysql/data/
[root@localhost data]# ls
auth ib_logfile0 localhost.err mongodb mysql-bin.000001 mysql-bin.000003 mysql-bin.index performance_schema
ibdata1 ib_logfile1 localhost.pid mysql mysql-bin.000002 mysql-bin.000004 mysql.error.log test
[root@localhost data]# mv auth /tmp/ ## 移动 auth 库,进行模拟故障操作。
[root@localhost data]# ls -ld auth
ls: 无法访问auth: 没有那个文件或目录
[root@localhost data]# mysql -u root -p < ~/auth.sql ## 执行导入恢复操作。
Enter password:
ERROR 1050 (42S01) at line 63: Table '`auth`.`users`' already exists
[root@localhost data]# ls -ld auth ## 确认恢复后的结果。
drwx------. 2 mysql mysql 4096 8月 1 05:17 auth
[root@localhost data]#
