openstack ii add compute node

# 在所有节点上执行：
yum -y install chrony

a：时间同步
# 控制节点：
# echo 'allow 10/8' >> /etc/chrony.conf
# systemctl restart chronyd
# cat /etc/chrony.conf | grep -v ^# | grep -v ^$

# 计算节点：
#  vim /etc/chrony.conf 修改第3行为
# server 10.69.15.111 iburst

sed -i 's/server 0.centos.pool.ntp.org/#&/' /etc/chrony.conf
sed -i 's/server 1.centos.pool.ntp.org/#&/' /etc/chrony.conf
sed -i 's/server 2.centos.pool.ntp.org/#&/' /etc/chrony.conf
sed -i 's/server 3.centos.pool.ntp.org/server 10.69.15.111 iburst/' /etc/chrony.conf

systemctl restart chronyd
systemctl status chronyd
netstat -lntup


# b：安装openstack客户端和openstack-selinux
yum install python-openstackclient openstack-selinux -y

计算节点compute1上：
# nova-compute调用libvirt来创建虚拟机 
yum -y install libvirt
systemctl  start  libvirtd
systemctl  enable  libvirtd
# 验证
virsh list

# 安装
yum install openstack-nova-compute -y
yum install openstack-utils.noarch -y
