这个错误是由于MySQL服务器无法访问MySQL数据目录/var/lib/mysql。这可能是由于以下原因之一:
1. 目录/var/lib/mysql不存在。请确保您已经创建了/var/lib/mysql目录,并且该目录存在于系统中。
2. 目录/var/lib/mysql的权限不正确。请确保mysql用户具有/var/lib/mysql目录的所有权,并且该目录具有正确的权限。
您可以尝试使用以下命令解决此问题:
1. 检查/var/lib/mysql目录是否存在。如果不存在,请使用以下命令创建一个新目录:
```
sudo mkdir /var/lib/mysql
```
2. 确保mysql用户拥有/var/lib/mysql目录的所有权:
```
sudo chown -R mysql:mysql /var/lib/mysql/
```
3. 确保/var/lib/mysql目录具有正确的权限。使用以下命令设置目录的权限:
```
sudo chmod 750 /var/lib/mysql
```
4. 尝试以mysql用户身份启动MySQL服务器:
```
sudo -u mysql mysqld --default-authentication-plugin=mysql_native_password
```
如果这些步骤没有解决问题,请提供更多详细信息,例如您是如何创建/var/lib/mysql目录的,以及您运行mysqld命令的完整命令行。

这段日志是一个 MySQL 集群中的一台机器(DONOR)在进行 SST(State Snapshot Transfer)时出现了错误。从日志中可以看到,xtrabackup_checkpoints 文件缺失导致 SST 失败,需要检查 DONOR 日志文件,以找到原因。因为 SST 失败,其他节点(joiner)无法接收状态,集群需要终止。最后,WSREP 进程由于遇到错误而退出。

这个错误信息提示是因为 MySQL 没有权限访问目录,需要修改文件夹的权限或者修改 MySQL 的配置文件来解决。具体操作步骤如下:
1. 修改文件夹的权限:使用 chmod 命令修改目录的权限,如 chmod 777 /path/to/directory。
2. 修改 MySQL 的配置文件:找到 my.cnf 文件,修改 datadir 的路径为正确的数据目录路径,并将目录的所有者修改为 MySQL 用户,例如:
```
[mysqld]
datadir=/var/lib/mysql
user=mysql
```
完成以上操作后,重新启动 MySQL 服务即可。如果还有问题,可以查看 MySQL 的日志文件来获取更多的信息。
