eucalyptus已启动，但出现错误

Question

我安装了eucalyptus，但当我启动eucalyptus时，它似乎是错误的。我检查文件eucanetd.log，它显示如下：

有什么帮助吗？

Answer 1

是的，我的系统上有/usr/sbin/dhcpd。这是eucalyptus的文件配置。

EUCALYPTUS="/"
LOGLEVEL="INFO"
EUCA_USER="eucalyptus"
CLOUD_OPTS=""
NC_PORT="8775"
CC_PORT="8774"
SCHEDPOLICY="ROUNDROBIN"
NODES="10.10.2.11"
NC_SERVICE="axis2/services/EucalyptusNC"
HYPERVISOR="kvm"
MAX_CORES="0"
INSTANCE_PATH="/var/lib/eucalyptus/instances"
USE_VIRTIO_ROOT="1"
USE_VIRTIO_DISK="1"
USE_VIRTIO_NET="1"
VNET_MODE="EDGE"
VNET_PRIVINTERFACE="br0"
VNET_PUBINTERFACE="br0"
VNET_BRIDGE="br0"
VNET_DHCPDAEMON="/usr/sbin/dhcpd"
METADATA_USE_VM_PRIVATE="N"
DISABLE_TUNNELING="Y"

Answer 2

你的系统上有/usr/sbin/dhcpd吗？如果没有，您需要使用/etc/eucalyptus/eucalyptus.conf文件中的VNET_DHCPDAEMON参数将Eucalyptus指向您的DHCP守护进程的正确位置，或者您需要安装一个DHCP守护进程并确保上面的参数指向它。

Answer 3

可能有port conflict with dnsmasq阻止dhcpd启动。检查节点控制器上的“默认”网络是否处于活动状态：

# virsh net-list

如果是，那么您可以使用：

# virsh net-destroy default

销毁默认网络并停止相关的dnsmasq进程，从而允许dhcpd运行。
