MySQL conflicts with mysql-5.1.66-2.el6_3.x86_64
卸载原有的mysql：
[root@rh6 oracle]#rpm -qa |grep mysql

[root@rh6 oracle]#rpm -e mysql-devel-5.1.66-2.el6_3.x86_64
[root@rh6 oracle]#rpm -e mysql-5.1.66-2.el6_3.x86_64
安装openssl：
下载openssl-1.0.1：
http://pkgs.org/centos-7/centos-x86_64/openssl-libs-1.0.1e-42.el7.x86_64.rpm/download/
[root@mysql2 soft]# rpm -ivh openssl-1.0.1e-42.el6.x86_64.rpm --force

[root@mysql2 soft]# rpm -qa |grep openssl
openssl-1.0.1e-42.el6.x86_64
openssl-1.0.0-27.el6.x86_64
openssl098e-0.9.8e-17.el6_2.2.x86_64
openssl-devel-1.0.0-27.el6.x86_64
----RedHat EL6自带openssl-1.0.0版本，对于Percona-Server应该安装openssl-1.0.1的版本，安装新版本后，问题解决。
2、解决“/usr/lib/libcrypto.so.10: no version information available ”
[root@mysql2 soft]# rpm -qa |grep openssl

卸载openssl旧版本：
[root@mysql2 soft]# rpm -e openssl-devel-1.0.0-27.el6.x86_64
[root@mysql2 soft]# rpm -e openssl-1.0.0-27.el6.x86_64
