[root@centos7 ~]# yum -y install percona-xtrabackup-24
[root@centos7 ~]# yum -y install qpress ##innobackupex支持压缩导出，这里安装压缩工具
[root@centos7 ~]# innobackupex -version ###如果出现如下提示表示安装成功，我这里2.4.15
xtrabackup: recognized server arguments: --server-id=11 --datadir=/data/mysql_data --tmpdir=/tmp --log_bin=bin.log --innodb_page_size=8192 --innodb_buffer_pool_size=2G --innodb_io_capacity=4000 --innodb_flush_method=O_DIRECT --innodb_undo_tablespaces=3 --innodb_log_file_size=128M --innodb_log_buffer_size=16777216

使用
备份全库到本地：
xtrabackup --user=root --password=1234qwer --socket=/tmp/mysql.sock --backup --target-dir=/u01/apps/mysql8/datas/all_db --parallel=8
xtrabackup --user=root --password=1234qwer --databases=mscode_auth --socket=/tmp/mysql.sock --backup --target-dir=/u01/bak/mysql/backup/mscode_auth_db_`date +%F` --parallel=4 --compress --compress-threads=2
--compress 压缩
测试实例
10分钟备份完： 13G
xtrabackup --user=root --password=1234qwer --socket=/tmp/mysql.sock --backup --target-dir=/u01/bak/mysql/backup/all_db_`date +%F` --parallel=4 --compress --compress-threads=2
scp -r -P 2828 /u01/bak/mysql/backup/all_db_2024-09-07 root@172.16.88.150:/u01/bak 123qwe!!
2.还原：20分钟
解压：
xtrabackup --decompress --parallel=4 --target-dir=/u01/bak/all_db_2024-09-07
systemctl stop mysqld
cd /u01/apps/mysql8/datas
mv mysql mysqlbak
mv /u01/bak/all_db_2024-09-07 ./mysql
xtrabackup --prepare --apply-log-only --target-dir=/u01/apps/mysql8/datas/mysql
chown -R mysql.mysql ./mysql
启动数据库：
systemctl start mysqld
