Where can I set the export MAVEN_OPTS command?

You can run the mvncommand, so its irrelevant wether you are using a .shor .batfile. For future reference you should keep in mind though that .bat files are for Windows, not Linux. Anyway, in the same shell you are running your mvn command in, do this first:
您可以运行该mvn命令，因此与您是否使用.sh或.bat文件无关。为了将来参考，您应该记住，尽管 .bat 文件适用于 Windows，而不是 Linux。无论如何，在您运行 mvn 命令的同一个 shell 中，请先执行以下操作：
export MAVEN_OPTS="-Xmx512M"
Then execute your mvncommand. Bump the number up if you still run out of memory.
然后执行你的mvn命令。如果您仍然内存不足，请增加数字。

If you have used "yum" to install Maven, then there will be a "mvn" command on your command path. On my system, it is a shell script. If you were going to "hack" a script, that would what you would edit.
如果您使用“yum”安装 Maven，那么您的命令路径上将有一个“mvn”命令。在我的系统上，它是一个 shell 脚本。如果您要“破解”一个脚本，那么您将要编辑的就是它。
But you shouldn't need to.

and where to set export MAVEN_OPTS COMMAND.

This is a very basic "How to use a Linux command shell" question.
这是一个非常基本的“如何使用 Linux 命令外壳”问题。
The answer is either you type is at the command prompt before you run the "mvn" command, or you add it to your shell initialization file and restart the shell as appropriate.
答案是要么在运行“mvn”命令之前在命令提示符下键入 is，要么将其添加到 shell 初始化文件中并根据需要重新启动 shell。
My advice would be to invest some time in reading a tutorial about how to use the Linux command shell. It will save you a lot of time in the long term.
我的建议是花一些时间阅读有关如何使用 Linux 命令外壳的教程。从长远来看，它将为您节省大量时间。
