我需要在我的Ubuntu Sever 14.04 x64上安装32位版本的Oracle Java
我按照jre 1.7的this答案和jdk 1.8的this进行了尝试。在这两种情况下，我都无法通过键入java -version
结果始终为-bash: /usr/bin/java: No such file or directory
请提前获取任何帮助。
ls -l /usr/bin/java会产生lrwxrwxrwx 1 root root 22 Sep 30 14:02 /usr/bin/java -> /etc/alternatives/java
和...
/etc/alternatives/java -> /usr/lib/jvm/jdk1.8.0_20/bin/java
此外：ldd /usr/lib/jvm/jdk1.8.0_20/bin/java生成not a dynamic executable
sudo updatedb; locate java：

假设/usr/bin/java确实指向java可执行文件，这可能是由于缺少共享库引起的。在我的系统上，/usr/bin/java最终指向/usr/lib/jvm/java-7-oracle/jre/bin/java
试试ldd /usr/lib/jvm/java-7-oracle/jre/bin/java。结果应该与此类似（这是64位）：
linux-vdso.so.1 => (0x00007fff7a7d7000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fa477851000)
libjli.so => /usr/lib/jvm/java-7-oracle/jre/bin/../lib/amd64/jli/libjli.so (0x00007fa47763a000)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fa477435000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fa47706f000)
/lib64/ld-linux-x86-64.so.2 (0x00007fa477a97000)
如果缺少某个库，请安装它。

我终于找到了它！
要运行32位Java，我需要为Ubuntu安装32位库（ia32-libs），如下所示：
sudo -i
cd /etc/apt/sources.list.d
echo "deb http://old-releases.ubuntu.com/ubuntu/ raring main restricted universe multiverse" >ia32-libs-raring.list
apt-get update
apt-get install ia32-libs
这来自here
现在我可以运行java -version并获得预期的响应
无论如何，请帮助
