物理备份下载恢复innobackupex部分操作参考官方文档。

第四部开始有变化

backup-my.cnf 配置文件如下

# This MySQL options file was generated by innobackupex.

# The MySQL server
[mysqld]
lower_case_table_names=1
innodb_checksum_algorithm=crc32
#innodb_log_checksum_alg#orithm=strict_crc32
innodb_data_file_path=ibdata1:200M:autoextend
innodb_log_files_in_group=2
innodb_log_file_size=8589934592
#innodb_fast_checksum=false
innodb_page_size=16384
#innodb_log_block_size=512

#master_key_id=0
#innodb_encrypt_algorithm=AES_256_CBC
sql_mode=''
skip-grant-tables

修改权限
chown -R mysql:mysql /data2

启动数据库：

mysqld --defaults-file=/data2/backup-my.cnf --user=mysql --datadir=/data2 --port=3357

mysql> use mysql
mysql> alter table proc engine=myisam;
mysql> alter table event engine=myisam;
mysql> alter table func engine=myisam;
mysql> flush privileges;
mysql> alter user 'aliyun_root'@'127.0.0.1' identified by '123456';

#aliyun_root 才有root权限。
修改backup-my.cnf 配置文件去掉 skip-grant-tables
重启数据库

mysql -ualiyun_root -p -P3357 -h127.0.0.1

再创建真正高权限用户。

mysql> create user super identified by '123456';

mysql> grant all privileges on *.* to super;
