Keycloak没有初始化MySQL数据库

【中文标题】Keycloak没有初始化MySQL数据库

【英文标题】：Keycloak not initializing MySQL database

【问题描述】：

我有这个工作，但由于其他问题决定从头开始安装。 尽管使用cp 1:1 复制了我的配置和Java 驱动程序包，但它现在将不再创建SQL 模式。我也尝试了“手动”初始化选项，但是没有生成 SQL 文件。

我从头开始执行的步骤是：

删除现有数据库 创建一个新数据库，授予相同的权限 移除 keycloak 目录 提取新的 keycloak tarball 复制和替换之前实例中的 keycloak 配置 从前一个实例复制 mysql JDBC 驱动程序包

我多次尝试重新创建它，但我无法弄清楚与第一次安装它有什么不同。我正在使用 Standalone HA 操作模式。

不胜感激。

我认为已经粘贴了相关位，但如果有任何帮助，这里是 server.log 作为文件：http://hugz.io/ryxgd9/server.log

【参考方案1】：

我能够通过使用默认的standalone-ha.xml 启动实例来解决这个问题，只包括驱动程序和数据源部分，然后才复制到其他修改的部分。
