1.
安装仓库：
yum
install
-y centos-release-openstack-newton
修改
openstack
源的地址为阿里云的地址（提高
yum
下载的速度）
sed
-i
"s#mirror.centos.org#mirrors.aliyun.com#g"
/etc/yum
.repos.d
/CentOS-OpenStack-newton
.repo
2.
安装
OpenStack
客户端：
yum
install
-y python-openstackclient
yum
install
-y openstack-selinux
rpm -qa python-openstackclient openstack-selinux
|
2.2 安装服务软件包

2.2.2 修改配置文件
这里很多配置和node1上面的nova配置文件一样，所以我们先把node1上面的配置文件拷贝过来，然后再修改配置，具体执行过程如下：

# scp /etc/nova/nova.conf 192.168.56.12:/etc/nova/
root@192.168.56.12's password:

查看权限是否正确
[root@linux-node2 ~]
# ll /etc/nova/nova.conf
-rw-r----- 1 root nova 290129 Dec 25 10:32
/etc/nova/nova
.conf
修改配置文件
[root@linux-node2 ~]
# vi /etc/nova/nova.conf
删除2行mysql的配置文件
connection=mysql+pymysql:
//nova
:nova@192.168.56.11
/nova_api
connection=mysql+pymysql:
//nova
:nova@192.168.56.11
/nova
