解决rinse安装CentOS 6报错找不到'/dev/urandom'的问题

Debian系统xen安装centos 6.3失败，报错找不到/dev/urandom。

错误如下

  File "/usr/lib64/python2.4/random.py", line 109, in seed
    a = long(_hexlify(_urandom(16)), 16)
OSError: [Errno 2] No such file or directory: '/dev/urandom'

解决方法

vim /usr/lib/rinse/common/30-dev-urandom.sh内容如下

#!/bin/sh
#
#  Ensure the chroot has /dev/random and /dev/urandom
#
# Dan Kegel
# --


#
#  Get the root of the chroot.
#
prefix=$1

#
#  Ensure it exists.
#
if [ ! -d "${prefix}" ]; then
  echo "Serious error - the named directory doesn't 	exist."
  exit
fi

#
#  Ensure we have /dev
#
if [ ! -d "${prefix}/dev" ]; then
    mkdir "${prefix}/dev"
fi


#
#  Create the nodes
#
echo "  Creating random devices in /dev"
if [ !  -e "${prefix}/dev/random" ]; then
    mknod -m 666 "${prefix}/dev/random" c 1 8
    chown root:root "${prefix}/dev/random"
fi
if [ !  -e "${prefix}/dev/urandom" ]; then
    mknod -m 666 "${prefix}/dev/urandom" c 1 9
    chown root:root "${prefix}/dev/urandom"
fi

然后

chmod +x /usr/lib/rinse/common/30-dev-urandom.sh

重新执行xen-create-image命令即可

xen-create-image --hostname=yourHostName --ip=yourIP --dist=centos-6 --install-method=rinse --force --arch=amd64
