如何在 Linux 中为所有用户设置 JAVA_HOME [英] How to set JAVA_HOME in Linux for all users

问题描述

我是 Linux 系统新手，Java 文件夹似乎太多了.

I am new to Linux system and there seem to be too many Java folders.

java -version 给了我:

java -version gives me:

• java 版本1.7.0_55"
• OpenJDK 运行时环境 (rhel-2.4.7.1.el6_5-x86_64 u55-b13)
• OpenJDK 64 位服务器 VM(构建 24.51-b03，混合模式)

当我尝试构建 Maven 项目时，出现错误:

When I am trying to build a Maven project , I am getting error:

Error: JAVA_HOME is not defined correctly.
We cannot execute /usr/java/jdk1.7.0_05/bin/java

您能否告诉我我需要为 root 用户和非 root 用户修改哪些文件以及 java 的确切位置?

Could you please tell me which files I need to modify for root as well as not-root user and where exactly is java located?

推荐答案

1. 找到/usr/lib/jvm/java-1.x.x-openjdk

2. vim/etc/profile

如果以非特权用户身份登录，则在前面加上 sudo，即.sudo vim

Prepend sudo if logged in as not-privileged user, ie. sudo vim

添加:

export JAVA_HOME="path that you found"

export PATH=$JAVA_HOME/bin:$PATH

注销并再次登录、重新启动或使用 source/etc/profile 立即在当前 shell 中应用更改

logout and login again, reboot, or use source /etc/profile to apply changes immediately in your current shell
