shell 复制代码######添加hdfs用户#####
useradd hdfs

su - hdfs报如下错误
javascript 复制代码-bash: /dev/null: Permission denied
-bash: /dev/null: Permission denied
-bash: /dev/null: Permission denied
-bash: /dev/null: Permission denied
-bash: /dev/null: Permission denied
-bash: /dev/null: Permission denied查看/dev/null的权限如下
csharp 复制代码ll /dev/null
-rwxr-xr-x 1 root root 9 Jul 25 17:07 null而其他正常的权限如下
csharp 复制代码crw-rw-rw- 1 root wheel 3, 2 Jul 25 14:08 null解决步骤如下：
bash 复制代码rm -f /dev/null; mknod -m 666 /dev/null c 1 3说明：重新reboot和recreate一下/dev/null即可。
