"/usr/bin/javac: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory"

Question

我在linux服务器RHEL 7中安装了jdk1.8.0_161。由于"/usr/bin/javac：/lib/ld-linux.so.2：错误的ELF解释器：没有这样的文件或目录"，我无法检查java版本。

以下是我安装 JDK 的步骤，

cd /opt/jdk1.8.0_161/
alternatives --install /usr/bin/java java /opt/jdk1.8.0_161/bin/java 2
alternatives --config java
There is 1 program that provides 'java'.
  Selection    Command
-----------------------------------------------
*+ 1           /opt/jdk1.8.0_161/bin/java
Enter to keep the current selection[+], or type selection number: 1
alternatives --install /usr/bin/jar jar /opt/jdk1.8.0_161/bin/jar 2
alternatives --install /usr/bin/javac javac /opt/jdk1.8.0_161/bin/javac 2
alternatives --set jar /opt/jdk1.8.0_161/bin/jar
alternatives --set javac /opt/jdk1.8.0_161/bin/javac
java -version
-bash: /usr/bin/java: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory

export JAVA_HOME=/opt/jdk1.8.0_161
export JRE_HOME=/opt/jdk1.8.0_161/jre
export PATH=$PATH:/opt/jdk1.8.0_161/bin:/opt/jdk1.8.0_161/jre/bin

Answer 1

看起来你在/opt/中解压缩了一个 tar.gz 文件。这个版本显然是试图使用32位/lib/ld-linux.so.2。(64位链接器/usr/lib64/ld-linux-x86-64.so.2 -> ld-2.17.so(

对于 EL7，请使用"rpm" 8u162http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html → JDK-8U162-Linux-X64.rpm ：

# cd Downloads/ && yum install ./jdk-8u162-linux-x64.rpm

# alternatives --install /usr/bin/java java /usr/java/jdk1.8.0_162/bin/java 2
# alternatives --install /usr/bin/javac javac /usr/java/jdk1.8.0_162/bin/javac 2
# alternatives --config java
# alternatives --config javac

没有问题...
