　　    系统版本：CentOS-7.0
　　
　　 控制节点：192.168.100.120
　　 计算节点：192.168.100.121
　　

　　

　　1.同步时间
[root@openstack ~]# hostnamectl set-hostname openstack
[root@openstack ~]# su -
[root@openstack ~]# ntpdate pool.ntp.org　　

　　2.添加mitaka源
[root@openstack ~]# wget http://repos.fedorapeople.org/repos/openstack/openstack-mitaka/rdo-release-mitaka-3.noarch.rpm
[root@openstack ~]# yum install -y centos-release-openstack-mitaka
[root@openstack ~]# yum install -y rdo-release-mitaka-3.noarch.rpm
[root@openstack ~]# yum upgrade -y　　

　　2.添加hosts解析
[root@openstack ~]# echo -e "192.168.100.120\t$(uname -n)" >> /etc/hosts
[root@openstack ~]# tail -n 1 /etc/hosts
192.168.254.140 openstack
[root@openstack ~]# ping -c 2 openstack

[mysqld]
default-storage-engine = innodb
innodb_file_per_table
collation-server = utf8_general_ci
