TSM Client安装遇到报错：由libc.so.6包缺失，引出64位系统默认不安装32位包的现象

报错现象：


[root@mylinux]# rpm -ivh TIVsm-BA.x86_64.rpm

error: Failed dependencies:


libc.so.6 is needed by TIVsm-BA-6.3.0-5.x86_64

解决办法：

出这个问题的原因是因为缺少glibc的32位rpm包，所以只需要补充安装上就可以了。但是需要注意的是，这个包也是与其他包关联的，所以需要用yum方式安装。

分析问题过程：

1、追踪libc.so.6




[root@TSMClt Client-v641]# find /tmp/TSMClient/Client-v641 -name "libc.so*"

[root@TSMClt Client-v641]#


[root@TSMClt Client-v641]# find /mnt -name "libc.so*"
[root@TSMClt Client-v641]#

[root@TSMClt Client-v641]# find / -name "libc.so*"

/usr/lib64/libc.so

/lib64/libc.so.6
[root@TSMClt Client-v641]#

[root@TSMClt Client-v641]# ls -al /lib64/libc.so.6
lrwxrwxrwx. 1 root root 12 Dec 20 00:13 /lib64/libc.so.6 -> libc-2.12.so

[root@TSMClt Client-v641]# rpm -qf /lib64/libc.so.6
glibc-2.12-1.7.el6.x86_64

我们从这里知道了这个包是属于glibc这个package，这是个转折点。

[root@TSMClt Client-v641]# rpm -qa | grep glibc
glibc-devel-2.12-1.7.el6.x86_64
glibc-2.12-1.7.el6.x86_64
glibc-common-2.12-1.7.el6.x86_64
glibc-headers-2.12-1.7.el6.x86_64

[root@TSMClt Client-v641]# yum search -y glibc

我们注意蓝色字体的内容，上下对比一下，我们看到了吧，问题的关键就是缺少这个i686的32位包。说明glibc这个package安装不完全。

2、32位包不默认不安装的改进方法

In Red Hat Enterprise Linux 5, if a package was available for both the main and the compatibility architectures, both architectures of the package were installed by default. In Red Hat Enterprise Linux 6, only the package for the primary architecture is installed by default.

To avoid problems during the backup-archive client and API installation on a 64-bit machine, be sure to install libstdc++ and compat-libstdc++ packages for 32-bit as well."

64位CentOS 6 通过yum安装软件的时候，默认不会安装32位的软件，这样会导致某些软件无法安装成功，实际上yum仓库里是有32位软件的，只是它默认只安装64位软件，如果需要安装32位，有2个方法，
假设你要安装libjpeg的32位版本

方法1：
先查询
yum list |grep libjpeg
指定安装32位版
yum install libjpeg.i686

方法2：
这是一种改进，一劳永逸的方法，如果作为系统管理员，这个可以提高工作效率，但是也需要评估风险，是否有64位持续不允许安装32位包的？
echo 'multilib_policy=all' >> /etc/yum.conf
以下命令会同时安装32位和64位版
yum install libjpeg
