在安装tomcat时报了错：
/lib/ld-linux.so.2: bad ELF interpreter: No such file or directory
本机环境：
[root@AY140518225150152f97Z bin]# uname -a
Linux AY140518225150152f97Z 2.6.32-358.6.2.el6.x86_64 #1 SMP Thu May 16 20:59:36 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
[root@AY140518225150152f97Z bin]# cat /etc/redhat-release
CentOS release 6.5 (Final)
bing了一下。（google 一直訪问不了。why？）解决方法：
是由于64位系统中安装了32位程序
解决方法：
yum install glibc.i686
于是安装了下： glibc.i686, 发现有出现错误： no package match!
找了n 多方案，都没有解决这个问题， 偶然间注意到：
/usr/local/tomcat/bin/catalina.sh: /usr/local/jdk1.8.0_05/bin/java: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory
于是想是不是jdk版本号不正确？ 检查了下jdk：jdk-8u5-linux-i586.tar.gz
果然，jdk 是32位的，上面红色部分看到了好几次没想到是jdk的问题，耽搁了好几天。
下了jdk-8u5-linux-x64.tar.gz，从新安装
tar -zvxf /home/sk/tools/jdk-8u5-linux-x64.tar.gz
再执行：./usr/local/tomcat/bin/configtest.sh
从新安装了64位的JDK之后：
[root@AY140518225150152f97Z bin]# ./configtest.sh
