<code>1.</code>
<code>安装仓库：</code>
<code>yum </code><code>install</code> <code>-y centos-release-openstack-newton</code>
<code>修改 </code>
<code>openstack </code>
<code>源的地址为阿里云的地址（提高 </code>
<code>yum </code>
<code>下载的速度）</code>
<code>sed</code> <code>-i </code><code>"s#mirror.centos.org#mirrors.aliyun.com#g"</code>
<code>/etc/yum</code><code>.repos.d</code><code>/CentOS-OpenStack-newton</code><code>.repo</code>
<code>2.</code>
<code>安装 </code>
<code>OpenStack </code>
<code>客户端：</code>
<code>yum </code><code>install</code> <code>-y python-openstackclient</code>
<code>yum </code><code>install</code> <code>-y openstack-selinux</code>
<code>rpm -qa python-openstackclient openstack-selinux</code>
2.2 安装服务软件包
<code>yum </code><code>install</code> <code>openstack-nova-compute</code>
2.2.1 安装报错
<code>Error downloading packages:</code>
<code> </code><code>1:librados2-10.2.2-0.el7.x86_64: [Errno 256] No </code><code>more</code> <code>mirrors to try.</code>
解放方法：
<code>[root@linux-node2 yum.repos.d]</code><code># cat CentOS-Ceph-Jewel.repo </code>
<code># CentOS-Ceph-Jewel.repo</code>
<code>#</code>
<code># Please see http://wiki.centos.org/SpecialInterestGroup/Storage for more</code>
<code># information</code>
<code>[centos-ceph-jewel]</code>
<code>name=CentOS-$releasever - Ceph Jewel</code>
<code>baseurl=http:</code><code>//mirror</code><code>.centos.org</code><code>/centos/</code><code>$releasever</code><code>/storage/</code><code>$basearch</code><code>/ceph-jewel/</code>
<code>gpgcheck=0 </code><code>#这里全部改成0</code>
<code>enabled=0 </code><code>#这里全部改成0</code>
<code>gpgkey=</code><code>file</code><code>:</code><code>///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-Storage</code>

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：

<code>[root@linux-node1 yum.repos.d]</code><code># scp /etc/nova/nova.conf 192.168.56.12:/etc/nova/</code>
<code>[email protected]'s password: </code>
<code>nova.conf </code>
<code>查看权限是否正确</code>
<code>[root@linux-node2 ~]</code><code># ll /etc/nova/nova.conf </code>
<code>-rw-r----- 1 root nova 290129 Dec 25 10:32 </code><code>/etc/nova/nova</code><code>.conf</code>
<code>修改配置文件</code>
<code>[root@linux-node2 ~]</code><code># vi /etc/nova/nova.conf </code>
<code> </code><code>删除2行mysql的配置文件</code>
<code>connection=mysql+pymysql:</code><code>//nova</code><code>:[email protected]</code><code>/nova_api</code>
<code>connection=mysql+pymysql:</code><code>//nova</code><code>:[email protected]</code><code>/nova</code>
<code>全部的配置如下：</code>
<code>[root@linux-node2 nova]</code><code># grep -n '^[a-z]' nova.conf</code>
<code>2:transport_url=rabbit:</code><code>//openstack</code><code>:[email protected]</code>
<code>15:auth_strategy=keystone</code>
<code>2063:use_neutron=True</code>
<code>3053:enabled_apis=osapi_compute,metadata</code>
<code>3267:firewall_driver = nova.virt.firewall.NoopFirewallDriver</code>
<code>4813:api_servers=http:</code><code>//192</code><code>.168.56.11:9292</code>
<code>5430:auth_uri = http:</code><code>//192</code><code>.168.56.11:5000</code>
<code>5431:auth_url = http:</code><code>//192</code><code>.168.56.11:35357</code>
<code>5432:memcached_servers = 192.168.56.11:11211</code>

2.3 虚拟机支持查看
<code>[root@linux-node2 nova]</code><code># egrep -c '(vmx|svm)' /proc/cpuinfo </code>
<code>2</code>
如果不支持，则显示为0 ，可以修改配置文件
<code>5672行 </code><code>#virt_type=kvm</code>
2.4 启动计算服务及其依赖，并将其配置为随系统自动启动
<code>[root@linux-node2 nova]</code><code># systemctl enable libvirtd.service openstack-nova-compute.service</code>
<code>Created </code><code>symlink</code> <code>from </code><code>/etc/systemd/system/multi-user</code><code>.target.wants</code><code>/openstack-nova-compute</code><code>.service to </code><code>/usr/lib/systemd/system/openstack-nova-compute</code><code>.service.</code>
<code>[root@linux-node2 nova]</code><code># systemctl start libvirtd.service openstack-nova-compute.service</code>
2.5 检查启动状态
<code>[root@linux-node2 nova]</code><code># ps aux|grep nova</code>
<code>nova 20997 2.3 7.0 1661660 130900 ? Ssl 14:18 3:13 </code><code>/usr/bin/python2</code> <code>/usr/binnova-compute</code>
在node1上检查状态
<code>[root@linux-node1 ~]</code><code># . admin-openstack </code>
