Linux在创建用户的时候遇到的错误：useradd: Permission denied.useradd：无法锁定 /etc/passwd，请稍后再试。

【故障现象】用groupdel删除test组时，报以上错误。原因为nginx组中有nginx用户(nginx的主组)。，所以这里需要再一次输入当前登录用户的密码（root用户就没有这种情况）useradd: 无法锁定 /etc/passwd,请稍后再试。可以使用sudo或者切换成root用户创建用户。passwd：所有的身份验证令牌已经成功更新。无效的密码： 密码少于 8 个字符。更改用户 user1 的密码。把用户添加到root分组当中。创建成功后，设置用户的密码。这样就解决了以上的问题！

系统环境：linux centos7.8 操作：创建用户 报错：useradd: cannot open /etc/passwd 解决过程： 查看这个文件的属性： # lsattr /etc/passwd ----i----------- /etc/passwd 发现有i属性 去掉这个属性： # chattr -i /etc/passwd 然后这个文件可以写了，但是还有几个文件不能写，一样的道理，都去掉i权限，就可以顺利创建成功了。 分析：i权限是什么呢？ 文件权限除了r、w、x外还

摘要 Linux系统添加用户时出现"cannot open /etc/group"错误，原因是/etc/group和/etc/gshadow文件被设置了不可修改的"i"隐藏属性。通过lsattr命令检查发现这两个文件有i属性标记，使用chattr -i命令移除该属性后问题解决。关键点是检查系统文件的隐藏属性权限。

出现这个原因主要是前面有人使用了下面命令把几个文件属性给修改了 chattr +i /etc/gshadow /etc/group/ /etc/shadow /etc/passwd 该命令的意思就是不允许把/etc/gshadow /etc/group/ /etc/shadow /etc/passwd这个目录给修改。而添加用户是必须修改这几个文件的。 因此，只需要执行下面的语句就可以了 ...
