这看起来是 Redis 数据库启动时遇到的错误,提示无法打开配置文件。可能是因为 Redis 所需的配置文件不存在或者路径不正确。您可以检查 Redis 的配置文件所在路径以及文件名是否正确,并确保文件存在。如果问题仍然存在,您可以尝试重新安装 Redis 或者检查 Redis 的日志文件以获取更详细的错误信息。

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。

这个错误是因为MySQL服务器无法切换到exporter用户。这可能是由于以下原因之一:
1. 用户exporter不存在。请确保您已经创建了一个名为exporter的用户,并且该用户存在于系统中。
2. 您没有足够的权限切换到exporter用户。请确保您有足够的权限以exporter用户身份运行mysqld进程。
您可以尝试使用以下命令解决此问题:
1. 检查exporter用户是否存在。如果不存在,请使用以下命令创建一个新用户:
```
sudo adduser exporter
```
2. 将exporter用户添加到mysql用户组中,以便它可以访问MySQL文件和目录:
```
sudo usermod -aG mysql exporter
```
3. 确保exporter用户拥有MySQL数据目录的所有权:
```
sudo chown -R mysql:mysql /var/lib/mysql/
```
4. 尝试使用以下命令以exporter用户身份启动MySQL服务器:
```
sudo -u exporter 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exporter用户的,以及您运行mysqld命令的完整命令行。
