一：准备

安装bridge和iscsi相关，虚拟机使用nova-volume服务

apt-get -y install open-iscsi open-iscsi-utils bridge-utils

重启网络服务

/etc/init.d/networking restart

2：设置环境变量

cat >/root/novarc <<EOF
export CONTROLLER_IP=10.1.199.17
export MASTER="$(/sbin/ifconfig eth0 | awk '/inet addr/ {print $2}' | cut -f2 -d ":")"
EOF

你需要根据你的情况，调整控制节点的IP。调整完后，运行下面命令，设置自己的变量

source novarc
echo "source novarc">>.bashrc

2：设置NTP

apt-get -y install ntp

编辑 /etc/ntp.conf, 指向控制节点的ntp服务器

# Use Ubuntu's ntp server as a fallback.
#server ntp.ubuntu.com
server 10.1.199.17

或者运行下面命令

sed -i -e " s/server ntp.ubuntu.com/server $CONTROLLER_IP/g" /etc/ntp.conf

二：安装Openstack

1：安装软件

计算节点，至少是需要安装nova-api，nova-network，nova-compute，还需要安装keystone client，

apt-get install -y nova-api  nova-common nova-compute \
nova-compute-kvm  nova-network  \
python-nova python-novaclient \
python-keystone python-keystoneclient

2: 编辑 /etc/nova/api-paste.ini , 修改末尾3行

#admin_tenant_name = %SERVICE_TENANT_NAME%
#admin_user = %SERVICE_USER%
#admin_password = %SERVICE_PASSWORD%
admin_tenant_name = service
admin_user = nova
admin_password = password

或者运行下面命令，直接复制控制节点的文件过来就可以。

scp root@$CONTROLLER_IP:/etc/nova/api-paste.ini /etc/nova/

3：编辑/etc/nova/nova.conf 文件，

这个文件和控制节点区别不大，就是vnc的地方，需要调整一下。

scp root@$CONTROLLER_IP:/etc/nova/nova.conf /etc/nova/nova.conf

修改vnc设置

###### NOVNC CONSOLE
novnc_enabled=true
novncproxy_base_url= http://10.1.199.17:6080/vnc_auto.html
vncserver_proxyclient_address=10.1.199.18
vncserver_listen=10.1.199.18

或者直接使用下面命令实现修改，其实就是用eth0的IP替换。

sed -i 's/^vncserver_proxyclient_address.*$/vncserver_proxyclient_address='"$(/sbin/ifconfig eth0 | awk '/inet addr/ {print $2}' | cut -f2 -d ":")"'/g' /etc/nova/nova.conf
sed -i 's/^vncserver_listen.*$/vncserver_listen='"$(/sbin/ifconfig eth0 | awk '/inet addr/ {print $2}' | cut -f2 -d ":")"'/g' /etc/nova/nova.conf

4：设置目录权限

chown -R nova:nova /etc/nova

nova.conf内容如下：

[DEFAULT] ###### LOGS/STATE #verbose=True verbose=False

###### AUTHENTICATION auth_strategy=keystone

###### SCHEDULER #--compute_scheduler_driver=nova.scheduler.filter_scheduler.FilterScheduler scheduler_driver=nova.scheduler.simple.SimpleScheduler

#####MISC use_deprecated_auth=false root_helper=sudo nova-rootwrap

5：重启服务

service libvirt-bin restart
service nova-network restart
service nova-compute restart
service nova-api restart

创建一个脚本，这样比较方便。restart.sh

#!/bin/bash
for a in libvirt-bin nova-network  nova-compute \
nova-api ; do service "$a" stop; done
for a in libvirt-bin nova-network  nova-compute \
nova-api ; do service "$a" start; done

root@node18:~# chmod +x restart.sh 

root@node18:~# ./restart.sh 
libvirt-bin stop/waiting
nova-network stop/waiting
nova-compute stop/waiting
nova-api stop/waiting
libvirt-bin start/running, process 4642
nova-network start/running, process 4662
nova-compute start/running, process 4673
nova-api start/running, process 4688

这时候大功告成。

可以运行 nova-manage service list 查看结果

5：重启服务

service libvirt-bin restart
service nova-network restart
service nova-compute restart
service nova-api restart

创建一个脚本，这样比较方便。restart.sh

#!/bin/bash
for a in libvirt-bin nova-network  nova-compute \
nova-api ; do service "$a" stop; done
for a in libvirt-bin nova-network  nova-compute \
nova-api ; do service "$a" start; done

root@node18:~# chmod +x restart.sh 

root@node18:~# ./restart.sh 
libvirt-bin stop/waiting
nova-network stop/waiting
nova-compute stop/waiting
nova-api stop/waiting
libvirt-bin start/running, process 4642
nova-network start/running, process 4662
nova-compute start/running, process 4673
nova-api start/running, process 4688

这时候大功告成。

可以运行 nova-manage service list 查看结果

发现计算节点没有加载进来。卸载nova-api，计算节点能加进来，再安装上nova-api，计算节点也可以加进来，原因未知。

另一个同事是这么安装的计算节点，没有出现过上述问题，下次可以按照这个实验一下：

apt-get -y install open-iscsi open-iscsi-utils bridge-utils
apt-get install -y nova-api  nova-common nova-compute nova-compute-kvm  nova-network python-nova python-novaclient python-keystone python-keystoneclient
