Ubuntu 在 OpenStack 中安装 DevStack 时收到错误

  1. Ubuntu 在 OpenStack 中安装 DevStack 时收到错误。

    stack@denny-pc:~$ cd /opt/devstack/`
`
stack@denny-pc:/opt/devstack$ ./stack.sh 
`
`

    文件权限：

    -rwxr-xr-x  1 root root 43892 1 month   8 18:35 stack.sh*

  2. 当到达第 605 行时，显示以下消息：

    +./stack.sh:read_password:605              set +o xtrace
touch: cannot touch '/opt/devstack/.localrc.password': Permission denied
Error on exit
Traceback (most recent call last):
  File "/opt/devstack/tools/worlddump.py", line 22, in <module>
    from distutils import spawn
ImportError: cannot import name 'spawn'

  3. stack.sh 的第 605 行内容如下：

    # Generic helper to configure passwords
function read_password {
    local xtrace
    xtrace=$(set +o | grep xtrace)
    set +o xtrace
    var=$1; msg=$2
    pw=${!var}

    if [[ -f $RC_DIR/localrc ]]; then
        localrc=$TOP_DIR/localrc
    else
        localrc=$TOP_DIR/.localrc.password
    fi

  # If the password is not defined yet, proceed to prompt user for a password.
    if [ ! $pw ]; then
        # If there is no localrc file, create one
        if [ ! -e $localrc ]; then
            touch $localrc
        fi

        # Presumably if we got this far it can only be that our
        # localrc is missing the required password.  Prompt user for a
        # password and write to localrc.

        echo ''
        echo '################################################################################'
        echo $msg
        echo '################################################################################'
        echo "This value will be written to ${localrc} file so you don't have to enter it "
        echo "again.  Use only alphanumeric characters."
   echo "If you leave this blank, a random default value will be used."
        pw=" "
        while true; do
            echo "Enter a password now:"
            read -e $var
            pw=${!var}
            [[ "$pw" = "`echo $pw | tr -cd [:alnum:]`" ]] && break
            echo "Invalid chars in password.  Try again:"
        done
        if [ ! $pw ]; then
            pw=$(generate_hex_string 10)
        fi
        eval "$var=$pw"
        echo "$var=$pw" >> $localrc
    fi
    # restore previous xtrace value
    $xtrace
}

  4. 主要错误信息：

    touch: cannot touch '/opt/devstack/.localrc.password': Permission denied

造成这个问题的原因是什么？
