OpenStack_Havana_Install_Guide 多节点安装总结6

四、计算节点

公共部分记得升级安装，环境变量设置完毕

1. 安装ntp
apt-get install -y ntp

#Comment the ubuntu NTP servers
sed -i 's/server 0.ubuntu.pool.ntp.org/#server 0.ubuntu.pool.ntp.org/g' /etc/ntp.conf
sed -i 's/server 1.ubuntu.pool.ntp.org/#server 1.ubuntu.pool.ntp.org/g' /etc/ntp.conf
sed -i 's/server 2.ubuntu.pool.ntp.org/#server 2.ubuntu.pool.ntp.org/g' /etc/ntp.conf
sed -i 's/server 3.ubuntu.pool.ntp.org/#server 3.ubuntu.pool.ntp.org/g' /etc/ntp.conf

sed -i 's/server ntp.ubuntu.com/server 128.6.3.33/g' /etc/ntp.conf

重启服务

service ntp restart

设置允许转发
#sed -i 's/#net.ipv4.ip_forward=1/net.ipv4.ip_forward=1/' /etc/sysctl.conf

# To save you from rebooting, perform the following
sysctl net.ipv4.ip_forward=1
编辑/etc/sysctl.conf
net.ipv4.conf.all.rp_filter=0
net.ipv4.conf.default.rp_filter=0

2. 安装Nova计算组件

# apt-get install nova-compute-kvm python-guestfs

（我这里包依赖一直出错，所以该组件使用了Grizzly版本的源，装完这个恢复H源。

vi grizzly.list

deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/grizzly main

）

设置内核可读
chmod 0644 /boot/vmlinuz*

# Remove the SQLite Database created by the packages
rm /var/lib/nova/nova.sqlite

编辑 /etc/libvirt/qemu.conf
cgroup_device_acl = [
"/dev/null", "/dev/full", "/dev/zero",
"/dev/random", "/dev/urandom",
"/dev/ptmx", "/dev/kvm", "/dev/kqemu",
"/dev/rtc", "/dev/hpet","/dev/net/tun"
]

删除
virsh net-destroy default
virsh net-undefine default

（上面这几步删除+编辑什么的，我不确定是不是必须的）

编辑 /etc/nova/nova.conf
