在64位Ubuntu服務器上安裝32位Java

Question

我需要在Ubuntu Sever 14.04 x64上安裝32位版本的Oracle Java

我試了一下下面這個答案JRE 1.7和這對JDK 1.8。 在這兩種情況下，我都無法通過鍵入java -version來驗證安裝是否成功

結果始終是-bash: /usr/bin/java: No such file or directory事先-bash: /usr/bin/java: No such file or directory Thx以獲得任何幫助。

ls -l /usr/bin/java 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 not a dynamic executable

Answer 1

假設/usr/bin/java確實指向java可執行文件，則可能是由於缺少共享庫引起的。 在我的系統上， /usr/bin/java最終指向/usr/lib/jvm/java-7-oracle/jre/bin/java

嘗試使用ldd /usr/lib/jvm/java-7-oracle/jre/bin/java 。 結果應與此類似（這是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)

如果缺少庫，請安裝它。

Answer 2

我終於找到了！

要運行32位Java，我需要為Ubuntu安裝32位庫（ 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

這是從這里來的

現在我可以運行java -version並得到預期的響應

謝謝您的幫助
