libc.so.6(GLIBC_2.14)(64bit) is needed by MySQL

记一次粗心大意！解决办法在最下面！

rpm安装MySQL时提升如下：

warning: MySQL-client-5.6.41-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
error: Failed dependencies:
libc.so.6(GLIBC_2.14)(64bit) is needed by MySQL-client-5.6.41-1.el7.x86_64
libc.so.6(GLIBC_2.17)(64bit) is needed by MySQL-client-5.6.41-1.el7.x86_64

首先查看一下glibc的版本

[root@Check1 ~]# strings /lib64/libc.so.6 | grep GLIBC
GLIBC_2.2.5
GLIBC_2.2.6
GLIBC_2.3
GLIBC_2.3.2
GLIBC_2.3.3
GLIBC_2.3.4
GLIBC_2.4
GLIBC_2.5
GLIBC_2.6
GLIBC_2.7
GLIBC_2.8
GLIBC_2.9
GLIBC_2.10
GLIBC_2.11
GLIBC_2.12
GLIBC_PRIVATE

可见没有安装时所需的2.14和2.17版本

下载安装

[root@Check1 ~]# wget http://ftp.gnu.org/gnu/glibc/glibc-2.14.tar.gz

编译安装

[root@Check1 ~]# tar xf glibc-2.14.tar.gz -C /usr/src/
[root@Check1 ~]# cd /usr/src/glibc-2.14/
[root@Check1 glibc-2.14]# mkdir build
[root@Check1 glibc-2.14]# cd build/
[root@Check1 build]# ../configure --prefix=/usr/local/glibc-2.14
[root@Check1 build]# make -j4
[root@Check1 build]# make install
[root@Check1 ~]# find / -name "ld.so.conf"
/etc/ld.so.conf
[root@Check1 ~]# cp /etc/ld.so.conf /usr/local/glibc-2.14/etc/
[root@Check1 ~]# mv /lib64/libc.so.6 /lib64/libc.so.6.bak

[root@Check1 ~]# LD_PRELOAD=/usr/local/glibc-2.14/lib/libc-2.14.so ln -s /usr/local/glibc-2.14/lib/libc-2.14.so /lib64/libc.so.6
[root@Check1 ~]# strings /lib64/libc.so.6 | grep GLIBC
GLIBC_2.2.5
GLIBC_2.2.6
GLIBC_2.3
GLIBC_2.3.2
GLIBC_2.3.3
GLIBC_2.3.4
GLIBC_2.4
GLIBC_2.5
GLIBC_2.6
GLIBC_2.7
GLIBC_2.8
GLIBC_2.9
GLIBC_2.10
GLIBC_2.11
GLIBC_2.12
GLIBC_2.13
GLIBC_2.14
GLIBC_PRIVATE

如果上面更新失败可用下面命令进行还原

$ LD_PRELOAD=/lib64/libc-2.12.so ln -s /lib64/libc-2.12.so /lib64/libc.so.6       // libc-2.12.so 此 项是系统升级前的版本

然而一顿操作之后并没有上面卵用

[root@Check1 ~]# rpm -ivh MySQL-client-5.6.41-1.el7.x86_64.rpm 
warning: MySQL-client-5.6.41-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
error: Failed dependencies:

libc.so.6(GLIBC_2.17)(64bit) is needed by MySQL-client-5.6.41-1.el7.x86_64

还原吧

[root@Check1 ~]# mv /lib64/libc.so.6.bak /lib64/libc.so.6
mv: overwrite `/lib64/libc.so.6'? y

于是我又默默的打开了下面的网站

然后就感觉哪里不对

emmm

然后就ls好几下

额~，去官网重新下载吧，这个安装包是之前安装留下来的，我直接用everything直接搜 mysql 5.6 bundle tar 就出来。。。下次一定要加上对应你系统的版本。。。
