centos7 使用mount -t cifs 挂载windows共享目录方法与问题解决

centos7 使用mount -t cifs 挂载windows共享目录方法与问题解决：

• 使用 域账号 密码 访问 //10.100.xx/Android 的windows 共享

mount -t cifs -o domain=test.com,username=administrator,password=test123 //192.168.1.10/share /usr/local/b

报错如下

mount -t cifs -o username=scj,password=xxxxx //10.100.xx/09.xx /usr/local/b
# 报错如下
[root@it519 ~]# mount -t cifs -o username="domain\xx",password="xx" //10.100.xx/Android /usr/local/a
mount: //10.100.xx/Android is write-protected, mounting read-only
mount: cannot mount //10.100.xx/Android read-only

解决：

# 需要安装cifs-utils
yum install cifs-utils.x86_64

安装完成后继续执行 报错如下

[root@it519 ~]# mount -t cifs -o username="domain\xx",password="xxx" //10.100.xx/Android /usr/local/a
mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

# 原因：命令中关于域的格式不对，正确的是:
# 建议用这个
mount -t cifs -o domain=test.com,username=administrator,password=test123 //192.168.1.10/share /databackup
# 或
mount -t cifs -o username=domain/administrator,password=test123 //192.168.1.10/share /databackup

# 再次挂载成功
[root@it519 ~]# mount -t cifs -o domain=test.com,username=xx,password=xxx //10.100.xx /Android /usr/local/a
# 卸载 挂载  umount
[root@it519 ~]# umount -v /usr/local/a/
umount: /usr/local/a (//10.100.xxx/Android) unmounted

其他报错

[root@www ~]# mount -t cifs -o username=name,password=123 //192.168.1.10/share /databackup

mount error(127): Key has expired
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

/var/log/messages内容：
Sep 26 09:56:05 www kernel: Status code returned 0xc0000224 NT_STATUS_PASSWORD_MUST_CHANGE
Sep 26 09:56:05 www kernel: CIFS VFS: Send error in SessSetup = -127
Sep 26 09:56:05 www kernel: CIFS VFS: cifs_mount failed w/return code = -127

原因：帐号的密码过期，将windows帐号的密码改为永不过期。

[root@www /]# mount -t cifs -o username=testuser,password=123 //192.168.214.128/npwpw /databackup
mount error(5): Input/output error
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

Sep 26 11:04:18 www kernel: CIFS VFS: cifs_mount failed w/return code = -5

原因：/databackup已经挂载了，需要先umonut，再mount 

让linux 启动自动挂载在/etc/fstab中增加

//192.168.1.100/test /media cifs defaults,username=manifold,password=manifolden 0
