Linux创建新用户时遇到的问题记录
创建新用户命令:
| useradd -d "/home/guest" -m -s "/bin/bash" guest | 
报错:
| useradd: cannot open /etc/passwd | 
按照网上的解决方案:
| chattr -ia /etc/passwd | 
此时/etc/passwd的属性:
| --------------e----- /etc/passwd | 
继续执行:
| useradd -d "/home/guest" -m -s "/bin/bash" guest | 
继续报错:
| useradd: cannot open /etc/passwd | 
继续查经验贴:
查到大概是因为是用的windows命令行登录Linux的原因,解决方案:
| 我这里是centOS,Ubuntu可以用 apt install dos2unix | 
作者原文:
You most likely introduced some error in the
passwd‘s syntax. You need to fix it.Might be through editing from Windows you have introduced Windows line endings, try:
sudo dos2unix /etc/passwd
英语好的可以自行理解,文章出处:https://askubuntu.com/questions/1339468/useradd-cannot-open-etc-passwd
总结:
第一步:
| chattr -ia /etc/passwd | 
第二布:
| yum install dos2unix | 
第三步设置密码:
| passwd guest |
