问题描述
我从此 link 下载了 liferay-ce-portal-tomcat-7.0-ga6 并尝试使用 ./startup.sh 运行 tomcat 服务器，结果如下：
newuser@my-Notebook:~/Downloads/liferay-ce-portal-tomcat-7.0-ga6-20180320170724974/liferay-ce-portal-7.0-ga6/tomcat-8.0.32/bin$ ./startup.sh

在日志文件中，catalina.out它给出了错误：
OpenJDK 64-Bit Server VM warning: Ignoring option MaxPermSize; support was removed in 8.0

in modular form will be supported via the concept of upgradeable modules.
Error: Could not create the Java Virtual Machine.

我使用的是 Ubuntu 18.04 LTS。
