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
innodb_undo_directory=./
innodb_undo_tablespaces=0
server_id=2827224867
#redo_log_version=1
#server_uuid=ed6cb933-ed9d-11eb-a1ae-043f72cc452c
#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;
