在安裝了xtrabackup后，再用下列命令登錄時報下列錯誤
[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
解決方法：查看該庫文件是否存在
[root@localhost ~]# find / -name libmysqlclient.so.16
/usr/lib64/libmysqlclient.so.16

3.查看系統中是否安裝了Percona軟件包
[root@localhost ~]# rpm -qa | grep Percona
Percona-Server-shared-51-5.1.73-rel14.12.624.rhel6.x86_64
4.將該軟件包卸載掉
[root@localhost ~]# rpm -e Percona-Server-shared-51-5.1.73 --nodeps
5.禁用percona的軟件源
[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.安裝mysql-libs軟件包
[root@localhost ~]# yum -y install mysql-libs
Loaded plugins: fastestmirror, refresh-packagekit, security
