版本：5.7.9
新装的CentOS 6.3 安装MySQL 5.7.9 出现的问题
1、首先卸载系统自带的mysql 5.1的包
yum -y remove mysql-libs-5.1.61-4.el6.x86_64
2、开始安装MySQL 5.7.9的包
3、报错：warning: mysql-community-server-5.7.9-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
error: Failed dependencies:
libnuma.so.1()(64bit) is needed by mysql-community-server-5.7.9-1.el6.x86_64
libnuma.so.1(libnuma_1.1)(64bit) is needed by mysql-community-server-5.7.9-1.el6.x86_64
libnuma.so.1(libnuma_1.2)(64bit) is needed by mysql-community-server-5.7.9-1.el6.x86_64
4、安装numactl即可
yum install numactl
