安装devstack中遇到的一些问题整理

1、执行stack.sh文件后提示

./stack.sh:528:check_path_perm_sanity
/opt/devstack/functions:582:die
[ERROR] /opt/devstack/functions:582 Invalid path permissions

检查functions代码

# Path permissions sanity check
   559    # check_path_perm_sanity path
   560    function check_path_perm_sanity {
   561        # Ensure no element of the path has 0700 permissions, which is very
   562        # likely to cause issues for daemons.  Inspired by default 0700
   563        # homedir permissions on RHEL and common practice of making DEST in
   564        # the stack user's homedir.
   565
   566        local real_path
   567        real_path=$(readlink -f $1)
   568        local rebuilt_path=""
   569        for i in $(echo ${real_path} | tr "/" " "); do
   570            rebuilt_path=$rebuilt_path"/"$i
   571
   572            if [[ $(stat -c '%a' ${rebuilt_path}) = 700 ]]; then
   573                echo "*** DEST path element"
   574                echo "***    ${rebuilt_path}"
   575                echo "*** appears to have 0700 permissions."
   576                echo "*** This is very likely to cause fatal issues for DevStack daemons."
   577
   578                if [[ -n "$SKIP_PATH_SANITY" ]]; then
   579                    return
   580                else
   581                    echo "*** Set SKIP_PATH_SANITY to skip this check"
   582                    die $LINENO "Invalid path permissions"
   583                fi
   584            fi
   585        done
   586    }

这段执行的是对stack账号的home目录检查权限，如果是700则返回错误。

检查/opt目录发现stack.sh自动创建的stack目录权限如下

[stack@localhost devstack]$ ll /opt/
总用量 4
drwxr-xr-x  15 root  root  4096 8月   9 12:06 devstack
drwxr-xr-x.  2 root  root     6 10月 31 2018 rh
drwx------   7 stack stack  131 8月   9 12:06 stack

修改stack目录权限

[stack@localhost opt]$ chmod 755 stack/
[stack@localhost opt]$ ll
总用量 4
drwxr-xr-x  15 root  root  4096 8月   9 12:06 devstack
drwxr-xr-x.  2 root  root     6 10月 31 2018 rh
drwxr-xr-x   7 stack stack  131 8月   9 12:06 stack

OK！

2、执行stack.sh文件后提示

touch: cannot touch ‘/opt/devstack/.localrc.password’: Permission denied
Error on exit
World dumping... see /opt/stack/logs/worlddump-2019-08-09-043124.txt for details

修改devstack目录权限

[stack@localhost opt]$ sudo chmod 777 devstack/
[stack@localhost opt]$ ll
总用量 4
drwxrwxrwx  15 root  root  4096 8月   9 12:06 devstack

OK！

3、执行stack.sh文件后提示

+ tools/install_pip.sh:install_get_pip:87  :   curl -f --retry 6 --retry-delay 5 -o /opt/devstack/files/get-pip.py https://bootstrap.pypa.io/get-pip.py

是由于已经安装了pip，可以直接在devstack/tools目录下，找到install_pip.py，注释掉install_get_pip这个函数调用。

4、执行stack.sh文件后提示

ERROR: Cannot uninstall 'enum34'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

可用通过手动升级的方式更新一下

sudo pip install enum34 --upgrade --ignore-installed enum34
