mysql客户端登录时报mysql: relocation error错误

报错内容：
[root@localhost ~]# mysql -u root -p
mysql: relocation error: mysql: symbol strmov, version libmysqlclient_16 not defined in file libmysqlclient.so.16 with link time reference

解决方法：

查看该库文件是否存在

[root@localhost ~]# find / -name libmysqlclient.so.16
/usr/lib64/libmysqlclient.so.16

查看mysql命令运行时所需要的库文件

从上面可以看到该文件已存在，并且已被调用

3.查看系统中是否安装了Percona软件包

[root@localhost ~]# rpm -qa | grep Percona
Percona-Server-shared-51-5.1.73-rel14.12.624.rhel6.x86_64

4.将该软件包卸载掉

[root@localhost ~]# rpm -e Percona-Server-shared-51-5.1.73 --nodeps

5.禁用percona的软件源

[root@localhost ~]# cd /etc/yum.repos.d
[root@localhost yum.repos.d]# ls
CentOS-Base.repo CentOS-Debuginfo.repo CentOS-fasttrack.repo CentOS-Media.repo CentOS-Vault.repo epel.repo epel-testing.repo percona-release.repo

[root@localhost yum.repos.d]# mv percona-release.repo percona-release.repo.disable

6.安装mysql-libs软件包

[root@localhost ~]# yum -y install mysql-libs

7.重新登录进行测试

[root@localhost ~]# mysql -u root -p
