CentOS 安装redis2.8.13 提醒"libc.so.6: version `GLIBC_2.14' not found"系统的glibc版本太低

以下在系统CentOS 6.3 x86_64上操作

1.试图运行程序，提示"libc.so.6: version `GLIBC_2.14' not found",原因是系统的glibc版本太低，软件编译时使用了较高版本的glibc引起的：

[work@zc-mc-face01 src]$ ./redis-server
./redis-server: /lib64/libc.so.: version `GLIBC_2.' not found (required by ./redis-server)

2.查看系统glibc支持的版本：

[work@zc-mc-face01 src]$ strings /lib64/libc.so. | grep GLIBC_
GLIBC_2.2.5
GLIBC_2.2.6
GLIBC_2.
GLIBC_2.3.2
GLIBC_2.3.3
GLIBC_2.3.4
GLIBC_2.
GLIBC_2.
GLIBC_2.
GLIBC_2.
GLIBC_2.
GLIBC_2.
GLIBC_2.
GLIBC_2.
GLIBC_2.
GLIBC_PRIVATE

[work@zc-mc-face01 src]$ rpm -qa | grep glibc
glibc-common-2.12-1.80.el6_3..x86_64
glibc-2.12-1.80.el6_3..x86_64
glibc-headers-2.12-1.80.el6_3..x86_64
glibc-devel-2.12-1.80.el6_3..x86_64

3.可以看到当前系统最高只支持2.12版本，所以需要安装新版本来解决这个问题：

　编译安装步骤如下：

a. 到http://www.gnu.org/software/libc/下载最新版本，我这里下载了glibc-2.14.tar.gz 这个版本，解压到任意目录准备编译

wget http://ftp.gnu.org/gnu/glibc/glibc-2.14.tar.gz

b.这里解压到～/glibc-2.14/　　

[work@zc-mc-face01 src]# cd /home/work/glibc-2.14/
[work@zc-mc-face01 glibc-2.14]# ls

c.在glibc源码目录建立构建目录，并cd进入构建目录

[work@zc-mc-face01 glibc-2.14]# mkdir build
[work@zc-mc-face01 glibc-2.14]# cd build

d.运行configure配置，make && sudo  make install

1. [work@zc-mc-face01 build]# ../configure --prefix=/opt/glibc-2.14

　　这一步如果config失败，显示错误如下：

checking whether ranlib is necessary... no
checking LD_LIBRARY_PATH variable... contains current directory
configure: error:
*** LD_LIBRARY_PATH shouldn't contain the current directory when
*** building glibc. Please change the environment variable
*** and run configure again.

　 此时首先查看LD_LIBRARY_PATH：

echo $LD_LIBRARY_PATH
/opt/soft/jdk/jre/lib/amd64/server:

　　而实际上这个路径的设置是有限制的：

# Test if LD_LIBRARY_PATH contains the notation for the current directory
# since this would lead to problems installing/building glibc.
# LD_LIBRARY_PATH contains the current directory if one of the following
# is true:
# - one of the terminals (":" and ";") is the first or last sign
# - two terminals occur directly after each other
# - the path contains an element with a dot in it

　　所以这里我们只需要去掉 LD_LIBRARY_PATH 最后的那个路径分隔符':'即可：

export LD_LIBRARY_PATH=/opt/soft/jdk/jre/lib/amd64/server

　　接下来继续运行

. [work@zc-mc-face01 build]# make -j4
. [work@zc-mc-face01 build]# sudo make install

4.临时修改环境变量

[work@zc-mc-face01 build]# export LD_LIBRARY_PATH=/opt/glibc-2.14/lib:$LD_LIBRARY_PATH

5.接下来就可以正常启动redis了

[work@zc-mc-face01 build]# cd ~/app/redis-2.8./src
[work@zc-mc-face01 src]# ./redis-server
