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
