二 安装服务软件包
2.1 安装库包
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
yum install openstack-nova-compute
2.2.1 安装报错
Error downloading packages: 1:librados2-10.2.2-0.el7.x86_64: [Errno 256] No more mirrors to try.
解放方法：
[root@linux-node2 yum.repos.d]# cat CentOS-Ceph-Jewel.repo # CentOS-Ceph-Jewel.repo # # Please see http://wiki.centos.org/SpecialInterestGroup/Storage for more # information [centos-ceph-jewel] name=CentOS-$releasever - Ceph Jewel baseurl=http://mirror.centos.org/centos/$releasever/storage/$basearch/ceph-jewel/ gpgcheck=0 #这里全部改成0 enabled=0 #这里全部改成0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-Storage
也可以从下面的链接下载包来安装

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：
[root@linux-node1 yum.repos.d]# scp /etc/nova/nova.conf 192.168.56.12:/etc/nova/ root@192.168.56.12‘s password: nova.conf 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 全部的配置如下： [root@linux-node2 nova]# grep -n ‘^[a-z]‘ nova.conf 2:transport_url=rabbit://openstack:openstack@192.168.56.11 15:auth_strategy=keystone 2063:use_neutron=True 3053:enabled_apis=osapi_compute,metadata 3267:firewall_driver = nova.virt.firewall.NoopFirewallDriver 4813:api_servers=http://192.168.56.11:9292 5430:auth_uri = http://192.168.56.11:5000 5431:auth_url = http://192.168.56.11:35357 5432:memcached_servers = 192.168.56.11:11211 5433:auth_type = password 5434:project_domain_name = default 5435:user_domain_name = default 5436:project_name = service 5437:username = nova 5438:password = nova 6470:url = http://192.168.56.11:9696 6471:auth_url = http://192.168.56.11:35357 6472:auth_type = password 6473:project_domain_name = default 6474:user_domain_name = default 6475:region_name = RegionOne 6476:project_name = service 6477:username = neutron 6478:password = neutron 6479:service_metadata_proxy = True 6480:metadata_proxy_shared_secret = oldboy 6716:lock_path=/var/lib/nova/tmp 6895:transport_url=rabbit://openstack:openstack@192.168.56.11 8372:enabled=true 8388:keymap=en-us 8395:vncserver_listen=0.0.0.0 8407:vncserver_proxyclient_address=192.168.56.12 8426:novncproxy_base_url=http://192.168.56.11:6080/vnc_auto.html
2.3 虚拟机支持查看
[root@linux-node2 nova]# egrep -c ‘(vmx|svm)‘ /proc/cpuinfo 2
如果不支持，则显示为0 ，可以修改配置文件
5672行 #virt_type=kvm
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
[root@linux-node2 nova]# systemctl enable libvirtd.service openstack-nova-compute.service Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-compute.service to /usr/lib/systemd/system/openstack-nova-compute.service. [root@linux-node2 nova]# systemctl start libvirtd.service openstack-nova-compute.service
2.5 检查启动状态
[root@linux-node2 nova]# ps aux|grep nova nova 20997 2.3 7.0 1661660 130900 ? Ssl 14:18 3:13 /usr/bin/python2 /usr/binnova-compute
在node1上检查状态
