Centos上openstack源代码安装（三）

九.安装nova（openstack）
下载nova-2011.2.tar.gz
http://openstack.org/projects/compute/latest-release/

tar -zxvf nova-2011.2.tar.gz
cd /opt/nova
python26 setup.py install

十.配置
复制nova-api.conf文件

cp /opt/nova/etc/nova-api.conf /etc/nova

复制目录

mkdir -p /var/lib/nova/CA
rsync -av /opt/nova/nova/CA/ /var/lib/nova/CA/

十一.配置mysql连接
修改nova.conf文件，将mysqlconnection指向192.168.1.105
创建数据库

mysql -uroot -h192.168.1.105 -p
create  database nova;

解决：设置nova库mysql的字符集
create database nova default character set latin1 collate latin1_swedish_ci；
再次执行：

nova-manage --flagfile /etc/nova/nova.conf db sync

十二.启动服务
使用如下脚本重启服务

export PATH=/usr/bin:/bin:/sbin:/usr/sbin

function screen_it {
    screen -S nova -X screen -t $1
    screen -S nova -p $1 -X stuff "$2$NL"
}
   screen -d -m -S nova -t nova
    sleep 1

# Opens up screen with following commands. You will have to go screen by screen
# and press RETURN to start them
screen_it api "/usr/bin/nova-api --nodaemon --flagfile /etc/nova/nova.conf"
screen_it objectstore "/usr/bin/nova-objectstore --nodaemon --flagfile /etc/nova/nova.conf"
screen_it compute "/usr/bin/nova-compute --nodaemon --flagfile /etc/nova/nova.conf"
screen_it network "/usr/bin/nova-network --nodaemon --flagfile /etc/nova/nova.conf"
screen_it scheduler "/usr/bin/nova-scheduler --nodaemon --flagfile /etc/nova/nova.conf"
#screen_it volume "/usr/bin/nova-volume --nodaemon --flagfile /etc/nova/nova.conf"
#screen_it test ". /etc/nova/novarc"
screen -S nova -x

推荐下面的命令到/etc/screenrc

hardstatus alwayslastline "%-Lw%{= BW}%50>%n%f* %t%{-}%+Lw%< %= %H"
