  • Samba共享及自动挂载测试

    要求:

    1、在server0服务器上安装配置samba,工作组为STAFF,共享目录/smb1, 共享名smb1,仅允许192.168.100.0/24网段中的主机访问。samba用户user1可以读取,密码为Ynyd1234; 并且在desktop0服务器自动挂载到/mnt/smb1目录下。

    2、配置共享目录/smb2,共享名smb2,仅允许192.168.100.0/24网段中的主机访问。
    仅允许用户user1读取, user2读写,密码都为Ynyd1234;客户机desktop0以multiuser方式自动挂接到/mnt/smb2

    服务端server0配置192.168.100.201:
    # yum install samba samba-client -y
    # firewall-cmd --permanent --add-service=samba
    # firewall-cmd --reload
    # systemctl enable smb nmb
    # systemctl restart nmb smb
    # netsat -antulp | grep smb
    # mkdir /smb1
    # mkdir /smb2
    # chmod 777 /smb1
    # chmod 777 /smb2
    # chcon -R -t samba_share_t /smb1
    # chcon -R -t samba_share_t /smb2

    # man 8 semanage-fcontext

    # semanage fcontext -a -t samba_share_t "/smb1(/.*)?"
    # semanage fcontext -a -t samba_share_t "/smb2(/.*)?"
    # ll -dZ /smb1
       drwxr-xr-x. root root unconfined_u:object_r:default_t:s0 /smb1
    # ll -dZ /smb2
       drwxr-xr-x. root root unconfined_u:object_r:default_t:s0 /smb2
    # useradd user1
    # useradd user2
    # smbpasswd -a user1
    # smbpasswd -a user2

    # vi /etc/samba/smb.conf
    [global]
             workgroup = STAFF   #此处修改为STAFF,并新增以下内容
    
    [smb1]
             path = /smb1
             #writable = yes #默认不加这句,user1及所有用户都只读,不可写。加上之后,所有用户都可写。
             hosts allow = 192.168.100.0/24
    
    [smb2]
             path = /smb2
             hosts allow = 192.168.100.0/24
             writable = no
             write list = user2   #user2可写,当然也可读。
             read list = user1    #user1可读,不可写。

    客户端desktop0配置:
    #yum install -y samba-client cifs-utils

    smbclient 连接测试

    1、/smb1对所有用户只读。
    [root@ldaptest ~]# smbclient //192.168.100.201/smb1 -U user1
    Enter user1's password: 
    Domain=[STAFF] OS=[Windows 6.1] Server=[Samba 4.6.2]
    smb: > ls
       .                                   D        0  Thu Dec 14 17:34:24 2017

    smb: > mkdir user1_mkdirtest
    NT_STATUS_MEDIA_WRITE_PROTECTED making remote directory user1_mkdirtest
    smb: > quit
    [root@ldaptest ~]# smbclient //192.168.100.201/smb1 -U user2
    Enter user2's password: 
    Domain=[STAFF] OS=[Windows 6.1] Server=[Samba 4.6.2]
    smb: > ls
       .                                   D        0  Thu Dec 14 17:34:24 2017
       ..                                 DR        0  Thu Dec 14 16:50:29 2017
       smb1filetest                                 0  Thu Dec 14 17:34:24 2017

    smb: > mkdir user2_mkdir_test
    NT_STATUS_MEDIA_WRITE_PROTECTED making remote directory user2_mkdir_test
    smb: > exit
    
    2、/smb2对user1用户只读,不可写。对user2用户可读可写。
    # smbclient //192.168.100.201/smb2 -U user1
    Enter user1's password: 
    Domain=[STAFF] OS=[Windows 6.1] Server=[Samba 4.6.2]
    smb: > ls
       .                                   D        0  Thu Dec 14 17:34:32 2017

       smb2filetest                                 0  Thu Dec 14 17:34:32 2017

    smb: > quit
    # smbclient //192.168.100.201/smb2 -U user2
    Enter user2's password: 
    Domain=[STAFF] OS=[Windows 6.1] Server=[Samba 4.6.2]
    smb: > ls
       .                                   D        0  Thu Dec 14 17:34:32 2017
       ..                                 DR        0  Thu Dec 14 16:50:29 2017
       smb2filetest                                 0  Thu Dec 14 17:34:32 2017

    smb: > exit
    [root@ldaptest ~]#
    
    smbcliet常用命令测试:
    ?或help [command] 提供关于帮助或某个命令的帮助 
    ![shell command]   执行所用的SHELL命令,或让用户进入 SHELL提示符 
    cd [目录]  切换到服务器端的指定目录,如未指定,则 smbclient 返回当前本地目录 
    lcd [目录]  切换到客户端指定的目录; 
    dir 或ls   列出当前目录下的文件; 
    exit 或quit    退出smbclient 
    get file1  file2 从服务器上下载file1,并以文件名file2存在本地机上;如果不想改名,可以把file2省略 
    mget file1 file2 file3  filen 从服务器上下载多个文件; 
    md或mkdir 目录 在服务器上创建目录 
    rd或rmdir 目录 删除服务器上的目录 
    put file1 [file2] 向服务器上传一个文件file1,传到服务器上改名为file2; 
    mput file1 file2 filen 向服务器上传多个文件
    
    # smbclient //192.168.100.201/smb2 -U user2
    Enter user2's password: 
    Interrupted by signal.
    cd /boot/
    # smbclient //192.168.100.201/smb2 -U user2
    Enter user2's password:

    smb: > lcd /tmp/    切换到客户机服务器的指定目录
    smb: > get initrd-2.6.32-431.el6.x86_64kdump.img 
    getting file initrd-2.6.32-431.el6.x86_64kdump.img of size 5089507 as initrd-2.6.32-431.el6.x86_64kdump.img (171386.4 KiloBytes/sec) (average 171387.0 KiloBytes/sec)

    客户机desktop0 配置自动挂载:

    # mkdir /mnt/smb1  创建挂载目录
    # mkdir /mnt/smb2

    挂载测试:

    [root@desktop ~]# mount -t cifs -o username=user1 //192.168.100.201/smb1 /mnt/smb1
    Password for user1@//192.168.100.201/smb1:  ********
    [root@desktop ~]# ls /mnt/smb1/
    smb1filetest
    [root@desktop ~]# mount -t cifs -o username=user2 //192.168.100.201/smb2 /mnt/smb2
    Password for user2@//192.168.100.201/smb2:  ********
    [root@desktop ~]# ls /mnt/smb2/
    initrd-2.6.32-431.el6.x86_64kdump.img  install.log  smb2filetest  user1_mkdir_test

    # cat /root/smb1.passwd   手动新建这两个密码文件
    username=user1
    password=Ynyd1234
    # cat /root/smb2.passwd
    username=user2
    password=Ynyd1234

    # vi /etc/fstab 添加如下两行

    # vi /etc/fstab 添加如下两行

    //192.168.100.201/smb1 /mnt/smb1        cifs    defaults,credentials=/root/smb1.passwd 0 0
    //192.168.100.201/smb2 /mnt/smb2        cifs    defaults,multiuser,credentials=/root/smb2.passwd,sec=ntlmssp 0 0

    [root@desktop ~]# umount /mnt/smb1
    [root@desktop ~]# umount /mnt/smb2/
    [root@desktop ~]# ls /mnt/smb1/
    [root@desktop ~]# ls /mnt/smb2/
    [root@desktop ~]# mount –a   该命令会自动使用/etc/fstab配置文件里的内容完成挂载。
    [root@desktop ~]# ls /mnt/smb1/
    smb1filetest
    [root@desktop ~]# ls /mnt/smb2/   
    initrd-2.6.32-431.el6.x86_64kdump.img  install.log  smb2filetest  user1_mkdir_test
    [root@ldesktop ~]# 自动挂载测试正常

    客户端配置写的有点多,其实大部分都是测试的内容。在挂载前,我们先手动测试下看能否挂载成功,之后,再配置自动挂载。

    总结起来就4点:1、安装samba-client cifs-utils 2、创建挂载目录 3、创建密码文件 4、编辑fstab配置文件。
