我使用create database dblife character set utf8创建了MySQL数据库。我使用MySQL版本8.0.11和MySQL连接器版本5.1.4。下载MySQL-connector后，我用.jar目录中的Mysql.jar替换了lib/ext文件。因此，当我运行Liferay服务器版本6.2时，它会给出以下错误，如下所示。
我在eclipse控制台上遇到错误：

此外，我无法在portal-ext.properties目录中添加liferay.home。当我添加这个portal-ext.properties文件，然后我得到错误：localhost的Liferay v6.2(tomcat7遇到了问题。
我检查了现有的解决方案liferay-not-working-with-mysql，但我看不到控制面板>管理工具中的Database Migration选项
谁能请我建议解决方案。我将非常感谢你。
安装Liferay时，它需要对数据库具有CREATE TABLE和其他DDL权限。确保将这些内容授予您正在运行Liferay的用户。创建表后，您可以撤消它们 - 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）。
另外，Liferay 6.2比mysql 8早了几年 - 可以安全地假设两者从未进行过一起测试，我建议使用经过测试的数据库，而不是尝试做任何人都没有的工作之前尝试过。您可以在compatibility matrix中找到企业支持的版本。
