今天在安装 MYSQL -5.7.9的时候，
rpm -Uvh mysql-community-server-5.7.9-1.el6.x86_64.rpm
提示：
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

最后发现是确实安装包 numactl 。
# yum install libnuma*
