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
yum install dos2unix
sudo dos2unix /etc/passwd

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 apt install dos2unix
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
sudo dos2unix /etc/passwd

第三步设置密码:

passwd guest
