ftp服務器無法用本地用戶登錄

Q：ftp服務器無法用本地用戶登錄

    [test@client home]$ ftp 192.168.221.129
    Connected to 192.168.221.129 (192.168.221.129).
    220 (vsFTPd 2.2.2)
    Name (192.168.221.129:test): test
    331 Please specify the password.
    Password:
    500 OOPS: cannot change directory:/home/test
    Login failed.

    //但是lftp可以用本地用戶登錄

A：

1. 是否是vsftp服務器端家目錄權限問題？

    [root@review1 home]# chmod +r test
    [root@review1 home]# ls
    test
    [root@review1 home]# ll
    total 4
    drwxr--r--. 2 test test 4096 May 27 10:57 test

再次登錄，無效。

2.檢查本地用戶test是否存在，是否有密碼

    [root@review1 ~]# tail -5 /etc/passwd
    saslauth:x:499:76:"Saslauthd user":/var/empty/saslauth:/sbin/nologin
    postfix:x:89:89::/var/spool/postfix:/sbin/nologin
    sshd:x:74:74:Privilege-separated SSH:/var/empty/sshd:/sbin/nologin
    ntp:x:38:38::/etc/ntp:/sbin/nologin
    test:x:500:500::/home/test:/bin/bash


    [root@review1 ~]# passwd test
    Changing password for user test.
    New password: 
    BAD PASSWORD: it is too simplistic/systematic
    BAD PASSWORD: is too simple
    Retype new password: 
    passwd: all authentication tokens updated successfully.

存在，密碼正常。

3.檢查客戶端本地用戶是否存在

    [root@client ~]# tail -5 /etc/passwd
    postfix:x:89:89::/var/spool/postfix:/sbin/nologin
    sshd:x:74:74:Privilege-separated SSH:/var/empty/sshd:/sbin/nologin
    test:x:500:500::/home/test:/bin/bash

    [root@client ~]# passwd test
    Changing password for user test.
    New password: 
    BAD PASSWORD: it is too simplistic/systematic
    BAD PASSWORD: is too simple
    Retype new password: 
    passwd: all authentication tokens updated successfully.

存在，設置正常。再次登錄，登錄失敗！

4.檢查、關閉selinux，重新連接，失敗。
5. 重啓vsftp，再次測試，成功。

    [root@mysql ~]# ftp 192.168.221.129
    Connected to 192.168.221.129 (192.168.221.129).
    220 (vsFTPd 2.2.2)
    Name (192.168.221.129:root): test
    331 Please specify the password.
    Password:
    230 Login successful.
    Remote system type is UNIX.
    Using binary mode to transfer files.

總結：
用戶無法進入家目錄，是 因爲 SElinux限制了本地ftp用戶的訪問，需要關閉SELinux，但是關閉後還需要重新啓動vsftp服務，否則無法生效！
