我在安装 hbase 时遇到了问题，最后遇到了一个有问题的“sudo apt-get”。它告诉我 JAVA_HOME 未设置，但实际上已经设置了。

根据
echo $(readlink -f /usr/bin/java | sed "s:bin/java::")
我的 JAVA_HOME 是
/usr/lib/jvm/java-6-openjdk-amd64/jre/
以下是它的回应：
jalal@mona:~$ echo $JAVA_HOME
/usr/lib/jvm/java-6-openjdk-amd64/jre/
sudo apt-get install请让我知道我首先该如何修复我的问题，然后如何使用安装 hbase sudo apt-get install？
通过添加
/usr/lib/jvm/java-6-openjdk-amd64/jre \
使用sudo nano /usr/lib/hbase/bin/hbase-config.sh
：
for candidate in \
/usr/lib/jvm/java-6-sun \
/usr/lib/jvm/java-1.6.0-sun-1.6.0.*/jre \
/usr/lib/jvm/java-1.6.0-sun-1.6.0.* \
/usr/lib/j2sdk1.6-sun \
/usr/java/jdk1.6* \
/usr/java/jre1.6* \
/Library/Java/Home ; do
if [ -e $candidate/bin/java ]; then
export JAVA_HOME=$candidate
break
fi
done
我不再接收JAVA_HOME not found错误。
但是现在我遇到了这个错误sudo apt-get install -f：
pam_mount(spawn.c:128): error setting uid to 0
有什么办法可以解决我的问题sudo apt-get install吗？
答案1
当您使用sudo命令时，它的行为与您执行的操作相同su。不同之处在于sudo它只执行一个给定的命令，然后立即退出。但更改用户的所有后果都存在。这意味着，如果您没有为root用户设置环境变量，它们将为空。您可以运行以下命令检查：
user@host:~$ su
Password:
root@host:/home/user$ echo $JAVA_HOME
root@host:/home/user$
root您可以像设置 一样设置 的变量。但更方便的方式是在文件user中设置它们/etc/environment
$ cat /etc/environment
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
JAVA_HOME="/usr/lib/jvm/default-java"
_JAVA_OPTIONS="-Dawt.useSystemAAFontSettings=on -Dswing.aatext=true"
