我使用创建数据库dblife字符集utf8创建了MySQL数据库。我使用 MySQL 版本 8.0.11 和 MySQL-connector 版本 5.1.4。下载 MySQL-connector 后，我将 .jar 文件替换为 lib/ext 目录中的 Mysql.jar 。因此，当我运行 Liferay 服务器版本 6.2 时，它给出了如下所示的错误。
我在 Eclipse 控制台上遇到错误:

此外，我无法在 liferay.home 目录中添加 portal-ext.properties 。当我添加此 portal-ext.properties 文件时，我收到错误:Liferay v6.2(tomcat7 at localhost has gone a Problem.
我已经检查了现有的解决方案 liferay-not-working-with-mysql ，但我在控制面板 > 管理工具中看不到数据库迁移 选项
有人可以建议我解决方案吗？我将非常感谢你。
最佳答案
当您安装Liferay时，它需要数据库上的CREATE TABLE和其他DDL权限。确保将这些权限授予运行 Liferay 的用户。一旦创建了表，您就可以撤销它们 - 安装后 Liferay 只需要标准的 CRUD 操作(直到您升级或部署需要此类权限的新组件)。
此外，Liferay 6.2 比 mysql 8 早了几年 - 可以安全地假设两者从未一起测试过，并且我建议使用经过测试的数据库，而不是试图让它们工作以前没有人尝试过。您可以在 compatibility matrix 中找到企业支持的版本。 .
关于mysql - 在 Windows 中无法将 MySQL 与 Liferay 连接，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/50834269/
