推荐答案

JAVA_OPTS 是一些服务器和其他 java 应用程序附加到执行 java 的调用的标准环境变量代码>命令.

JAVA_OPTS is the standard environment variable that some servers and other java apps append to the call that executes the java command.

例如在tomcat中定义JAVA_OPTS='-Xmx1024m'，启动脚本会执行java org.apache.tomcat.Servert -Xmx1024m

For example in tomcat if you define JAVA_OPTS='-Xmx1024m', the startup script will execute java org.apache.tomcat.Servert -Xmx1024m

如果你是在 Linux/OSX 上运行，你可以在调用启动脚本之前设置 JAVA_OPTS

If you are running in Linux/OSX, you can set the JAVA_OPTS, right before you call the startup script by doing

JAVA_OPTS='-Djava.awt.headless=true'

这只会在控制台打开时持续.要使其更永久，您可以将其添加到您的 ~/.profile 或 ~/.bashrc 文件中.

This will only last as long as the console is open. To make it more permanent you can add it to your ~/.profile or ~/.bashrc file.
