redis的README中有说明：
In case of build errors when trying to build a 32 bit binary of Redis, try
the following steps:
* Install the packages libc6-dev-i386 (also try g++-multilib).
但是centos中并没有libc6-dev-i386这个包，查了一下需要的头文件在glibc-devel这个包中。
安装glibc-devel:

继续make，还是报同样的错误。但是明明已经安装了glibc-devel包啊？
[rao@~ redis-2.8.9]$ ls /usr/include/gnu/ libc-version.h lib-names.h stubs-64.h stubs.h
确实没有所需要的头文件“gnu/stubs-32.h”。
再检查安装glibc-devel包的过程，其安装的包名称是“glibc-devel-2.12-1.132.el6.x86_64.rpm”，从yum的源（http://mirrors.163.com/centos/6/os/x86_64/Packages/）中下载该rpm包，解压察看发现：该rpm包中确实没有头文件“gnu/stubs-32.h”。
也就是说：通过“sudo yum install glibc-devel”命令安装的“glibc-devel-2.12-1.132.el6.x86_64.rpm”中并不是我们需要的rpm包？
那么到底需要安装哪个rpm包呢？
刚才在yum的源中，注意到存在两个版本号相同的glibc-devel：
glibc-devel-2.12-1.132.el6.i686.rpm 25-Nov-2013 03:29 1001468
glibc-devel-2.12-1.132.el6.x86_64.rpm 25-Nov-2013 03:31 1001012
第二个就是刚才通过“sudo yum install glibc-devel”命令安装的包，从名字看是64位系统的，那么第一个就应该是32位的。
下载第一个包“glibc-devel-2.12-1.132.el6.i686.rpm”，解压看看里面有什么文件：
[rao@~ Packages]$ rpm2cpio glibc-devel-2.12-1.132.el6.i686.rpm | cpio -div ./usr/include/gnu/stubs-32.h ./usr/lib/Mcrt1.o ./usr/lib/Scrt1.o ./usr/lib/crt1.o ./usr/lib/crti.o ./usr/lib/crtn.o ./usr/lib/gcrt1.o ./usr/lib/libBrokenLocale.so ./usr/lib/libanl.so ./usr/lib/libbsd-compat.a ./usr/lib/libbsd.a ./usr/lib/libc.so ./usr/lib/libc_nonshared.a ./usr/lib/libcidn.so ./usr/lib/libcrypt.so ./usr/lib/libdl.so ./usr/lib/libg.a ./usr/lib/libieee.a ./usr/lib/libm.so ./usr/lib/libmcheck.a ./usr/lib/libnsl.so ./usr/lib/libnss_compat.so ./usr/lib/libnss_dns.so ./usr/lib/libnss_files.so ./usr/lib/libnss_hesiod.so ./usr/lib/libnss_nis.so ./usr/lib/libnss_nisplus.so ./usr/lib/libpthread.so ./usr/lib/libpthread_nonshared.a ./usr/lib/libresolv.so ./usr/lib/librpcsvc.a ./usr/lib/librt.so ./usr/lib/libthread_db.so ./usr/lib/libutil.so ./usr/share/info/libc.info-1.gz ./usr/share/info/libc.info-10.gz ./usr/share/info/libc.info-11.gz ./usr/share/info/libc.info-2.gz ./usr/share/info/libc.info-3.gz ./usr/share/info/libc.info-4.gz ./usr/share/info/libc.info-5.gz ./usr/share/info/libc.info-6.gz ./usr/share/info/libc.info-7.gz ./usr/share/info/libc.info-8.gz ./usr/share/info/libc.info-9.gz ./usr/share/info/libc.info.gz 1920 块
可以看到里面刚好有我们需要的头文件“gnu/stubs-32.h”。
那么执行“sudo yum install glibc-devel”命令为什么安装的是“glibc-devel-2.12-1.132.el6.x86_64.rpm”而不是我们需要的“glibc-devel-2.12-1.132.el6.i686.rpm”包呢？
我猜是在64位系统中，yum在安装时发现同一个包存在两个版本时，默认优先安装64位的rpm包。
那该怎么让yum安装“glibc-devel-2.12-1.132.el6.i686.rpm”呢？
既然我已经下载了该包，就用rpm命令手动安装试试看：
[rao@~ redis-2.8.9]$ sudo rpm -ivh glibc-devel-2.12-1.132.el6.i686.rpm error: Failed dependencies: libBrokenLocale.so.1 is needed by glibc-devel-2.12-1.132.el6.i686 libanl.so.1 is needed by glibc-devel-2.12-1.132.el6.i686 libcidn.so.1 is needed by glibc-devel-2.12-1.132.el6.i686 libcrypt.so.1 is needed by glibc-devel-2.12-1.132.el6.i686 libdl.so.2 is needed by glibc-devel-2.12-1.132.el6.i686 libm.so.6 is needed by glibc-devel-2.12-1.132.el6.i686 libnsl.so.1 is needed by glibc-devel-2.12-1.132.el6.i686 libnss_compat.so.2 is needed by glibc-devel-2.12-1.132.el6.i686 libnss_dns.so.2 is needed by glibc-devel-2.12-1.132.el6.i686 libnss_files.so.2 is needed by glibc-devel-2.12-1.132.el6.i686 libnss_hesiod.so.2 is needed by glibc-devel-2.12-1.132.el6.i686 libnss_nis.so.2 is needed by glibc-devel-2.12-1.132.el6.i686 libnss_nisplus.so.2 is needed by glibc-devel-2.12-1.132.el6.i686 libresolv.so.2 is needed by glibc-devel-2.12-1.132.el6.i686 librt.so.1 is needed by glibc-devel-2.12-1.132.el6.i686 libthread_db.so.1 is needed by glibc-devel-2.12-1.132.el6.i686 libutil.so.1 is needed by glibc-devel-2.12-1.132.el6.i686
看来不行，缺少一堆依赖文件。
网上查到可以通过"yum install glibc-devel.i686"命令安装32位的glibc-devel：

可以看到yum命令确实只能找到64位的rpm包，但yum的源中又确实有32位的rpm包啊。。。问题处在哪呢？
打开yum的配置文件/etc/yum.conf看看，发现一行可疑的配置：
exclude=*.i?86 kernel kernel-xen kernel-debug
从内容看，似乎yum刻意忽略了32位的rpm包？
不管三七二十一，去掉试试看，修改成如下：
exclude= kernel kernel-xen kernel-debug
[rao@AY1404062027584053a1Z etc]$ yum list |grep glibc glibc.x86_64 2.12-1.132.el6 @base glibc-common.x86_64 2.12-1.132.el6 @base glibc-devel.x86_64 2.12-1.132.el6 @base glibc-headers.x86_64 2.12-1.132.el6 @base compat-glibc.x86_64 1:2.5-46.2 base compat-glibc-headers.x86_64 1:2.5-46.2 base glibc.i686 2.12-1.132.el6 base glibc-devel.i686 2.12-1.132.el6 base glibc-static.i686 2.12-1.132.el6 base glibc-static.x86_64 2.12-1.132.el6 base glibc-utils.x86_64 2.12-1.132.el6 base
果然多了一个32位的rpm包，看来有戏。
再执行命令”sudo yum install glibc-devel.i686",终于安装成功了。
再继续编译redis，很快就搞定了。
总结：
原因：阿里云64位centos6.3上，默认的yum配置不安装32位的rpm包，导致编译redis需要的“glibc-devel.i686”无法被安装。
解决办法：修改yum的配置文件/etc/yum.conf,将”exclude=*.i?86 kernel kernel-xen kernel-debug“改成”exclude= kernel kernel-xen kernel-debug“即可。
不确定这个配置是centos的默认配置，还是阿里云的修改，总之很坑爹，浪费了我一个美好的周末。
