docker的mysql数据丢失，被黑客攻击

1、第一步进入docker的容器中。

复制代码

docker exec -it mysql mysql -uroot -p123456

2、进入mysql查看权限

markdown 复制代码

use mysql;
select host,user,authentication_string from mysql.user;

3、查看binlog

复制代码

mysql> SHOW VARIABLES LIKE 'log_bin%';
+---------------------------------+-----------------------------+
| Variable_name                   | Value                       |
+---------------------------------+-----------------------------+
| log_bin                         | ON                          |
| log_bin_basename                | /var/lib/mysql/binlog       |
| log_bin_index                   | /var/lib/mysql/binlog.index |
| log_bin_trust_function_creators | OFF                         |
| log_bin_use_v1_row_events       | OFF                         |
+---------------------------------+-----------------------------+

4、查询是否有binlog日志

$root@VM-12-13-opencloudos \~$ # cd /home/mysql/data

$root@VM-12-13-opencloudos data$ # ls

auto.cnf binlog.000003 binlog.000007 ca.pem '#ib_16384_1.dblwr' ib_logfile1 mysql.ibd server-cert.pem undo_002

bb92e54a9f51.err binlog.000004 binlog.000008 client-cert.pem ib_buffer_pool ibtmp1 performance_schema server-key.pem

binlog.000001 binlog.000005 binlog.index client-key.pem ibdata1 '#innodb_temp' private_key.pem sys

binlog.000002 binlog.000006 ca-key.pem '#ib_16384_0.dblwr' ib_logfile0 mysql public_key.pem undo_00

5、使用binlog恢复

mysqlbinlog --start-position=起始位置 --stop-position=结束位置 binlog.000007 | mysql -u 用户名 -p

先备份当前而

复制代码

   mysqldump -uroot -p T > /path/xxx.sql;   # 备份数据库
    show master status;   # 查看当前的position位置，此时值为154

7.通过mysqlbinlog命令从binlog日志中导出可执行的SQL文件，并将数据导入到mysql

复制代码

 docker exec -it mysql bash
 cd var/lib/mysql
 
mysqlbinlog /var/lib/mysql/binlog.000007  | mysql -uroot -p 123456

提示失败

复制代码

ERROR: Binlog has bad magic number; It's not a binary log file that can be used by this version

8、还是修改密码吧

markdown 复制代码

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456!';
flush privileges;

docker exec -it mysql mysql -uroot -p123456

use mysql;
select host,user,authentication_string from mysql.user;

发现远程登录 需要个新密码了。
