64位CentOS安装32位程序库(兼容32位程序运行)

缘由: 有时候需要用linux运行与测试程序，然而发现64位的Linux系统在检测32位程序时找不到/lib/ld-linux.so.2; 又由于公司研发环境不能连接外网,因而无法在线安装。
目的: linux系统无法连接外网的情况下,通过配置yum本地源,安装32位程序运行的兼容库(xulrunner.i686);CentOS6.5-X64.iso中有xulrunner-17.0.10-1.el6.centos.i686
备注: CentOS6.6的xulrunner-17.0.10-1.el6.centos.i686.rpm在第二张iso盘中,先从第二张盘中cp出一份xulrunner-17.0.10-1.el6.centos.i686.rpm到 /opt/

方法/步骤:(root用户)

1. mount -t iso9660 /dev/cdrom /media [CentOS6自动挂载]

2. cd /etc/yum.repos.d/

3. mkdir tmp;mv *.* ./tmp/

4. 建立yum配置文件 vim /etc/yum.repos.d/local.repo

    [base]
    name=CentOS6-local
    baseurl=file:///media/CentOS_6.6_Final
    gpgcheck=0
    enabled=1
    gpgkey=file:///media/CentOS_6.6_Final/RPM-GPG-KEY-CentOS-6

5. 修改yum源地址(cp /usr/lib/python2.6/site-packages/yum/yumRepo.py /usr/lib/python2.6/site-packages/yum/yumRepo.py_bak)

    vim /usr/lib/python2.6/site-packages/yum/yumRepo.py
    输入/remote可以查找remote单词
    找到remote = url + '/' + relative 修改为: remote = '/yum' + relative

6. 测试安装(xulrunner-17.0.10-1.el6.centos.i686.rpm)

    cd /opt
    yum clean all
    yum install xulrunner.i686

7. 如果系统显示安装一大堆i686包就代表OK了.
