Ubuntu 12.04 Openstack Essex 安装(多节点) – 陈沙克日志
多节点的安装,其实也就是增加一个计算节点。
为了实现网络的高可用,每个计算节点,都会安装nova-network。并且每个计算节点都需要安装nova-api。
1:设置网络 /etc/network/interface
auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 10.1.199.18 hwaddress ether 00:25:90:67:ce:0c netmask 255.255.255.0 network 10.1.199.0 gateway 10.1.199.1 dns-search chenshake.com dns-nameservers 8.8.8.8 auto eth1 iface eth1 inet manual up ifconfig eth1 up
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 $2}' | cut -f2 -d ":")"'/g' /etc/nova/nova.conf
4:设置目录权限
chown -R nova:nova /etc/nova
5:重启服务
service libvirt-bin restart service nova-network restart service nova-compute restart service nova-api restart
创建一个脚本,这样比较方便。restart.sh
#!/bin/bash for a in libvirt-bin nova-network nova-compute \ nova-api ; do service "$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
