ubuntu22.04更改mysql8.0数据目录失败

ubuntu22.04安装mysql8.0,在修改数据文件位置时，已经进行如下操作：
1.创建新的目录和复制文件 sudo rsync -a /var/lib/mysql /data/
2.修改配置文件/etc/mysql/mysql.conf.d/mysqld.cnf的datadir
3.修改/etc/apparmor.d/usr.sbin.mysqld的以下属性

# Allow data dir access
  /data/mysql/ r,
  /data/mysql/** rwk,

4.修改控制文件/etc/apparmor.d/abstractions/mysql 如下：
/data/mysql{,d}/mysql{,d}.sock rw,

5.重启systemctl restart apparmor 没有报错
6.重启mysql报错
报错信息如下：

× mysql.service - MySQL Community Server

参考了https://blog.csdn.net/yuanjiaqi_k/article/details/130271526，还是不行

请各位帮助

chmod -R 755 /data
chown -R mysql.mysql /data/mysql
执行这两条语句赋下权限

lsattr /data看看还有没有隐藏的权限问题
