Resolving Dependencies
There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help).

停止数据库
[root@k8s-131 mysql]# systemctl stop mysql
删除data数据库目录
[root@k8s-131 mysql]# mv data/ databack
新建data数据库目录
[root@k8s-131 mysql]# mkdir /usr/local/mysql/data/
记得授权
[root@k8s-131 mysql]# chown -R mysql:mysql /usr/local/mysql/data
[root@k8s-131 mysql]# xtrabackup --prepare --apply-log-only --target-dir=/back/full/
[root@k8s-131 mysql]# xtrabackup --prepare --target-dir=/back/full/
# 复制备份数据到新的数据目录
xtrabackup --copy-back --target-dir=/back/full/
# 设置新的数据目录的权限
chown -R mysql:mysql /usr/local/mysql/data/*
# 启动 MySQL 服务器
systemctl start mysql
查看就是全量备份的数据
完成了
