2023-06-08T10:46:25.851539+08:00 0 [ERROR] [MY-000067] [Server] unknown variable 'collation_database=utf8mb4_general_ci;'. 正确的配置是什么
时间: 2024-03-15 21:47:39 浏览: 129
正确的配置应该是将 `collation_database` 的值设置为 `utf8mb4_general_ci`,不需要在后面加分号。在 MySQL 的配置文件中,可以在 `[mysqld]` 段中添加以下行来设置该变量:
```
[mysqld]
collation_database = utf8mb4_general_ci
```
请注意,这里只是设置了 `collation_database` 的值,并没有设置字符集编码,需要在 `[mysqld]` 段中添加 `character_set_server` 选项来设置字符集编码,例如:
```
[mysqld]
collation_database = utf8mb4_general_ci
character_set_server = utf8mb4
```
设置完成后,需要重启 MySQL 服务才能生效。

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。

这段信息是一个Java Spring应用程序在启动时输出的日志信息。其中包含以下内容:
- 时间戳:2023-06-08T11:32:23.660+08:00 表示日志输出的时间。
- 日志级别:INFO 表示这是一条信息级别的日志,通常用来表示应用程序的正常运行状态。
- 线程信息:[nio-8088-exec-2] 表示这条日志信息是由哪个线程输出的。
- 日志内容:该段日志信息中输出了Spring DispatcherServlet初始化的相关信息,包括初始化的Servlet名称、初始化完成的时间等。
这些日志信息通常被用来帮助开发人员定位和解决应用程序中的问题,比如排查应用程序启动失败、性能问题等。
