1.安装samba

[root@manager data]# yum install samba samba-client -y

2.修改smb.conf为以下内容

[root@manager samba]# cat /etc/samba/smb.conf
# See smb.conf.example for a more detailed config file or
# read the smb.conf manpage.
# Run 'testparm' to verify the config is correct after
# you modified it.

[global]
        workgroup = SAMBA
        security = user
        guest account = nobody
        passdb backend = tdbsam
        log file = /var/log/samba/log.%m
        map to guest = Bad User

[public]
        comment = public
        path = /data/samba
        public = yes
        writable = yes
        browseable = yes 
        guest ok = yes

3.创建相关目录

[root@manager samba]# mkdir -p /data/samba/
[root@manager samba]# chmod 777 /data/samba/

4.启动samba

[root@manager samba]# systemctl restart smb
[root@manager samba]# systemctl enable smb
[root@manager samba]# systemctl status smb

测试验证

win10

win10 匿名访问samba可能会有这个报错

解决方法（推荐方法二）

方法一

按win+R 运行：输入”gpedit.msc” 打开组策略—计算机配置—管理模板—网络—Lanman工作站—启用不安全的来宾登录—选择已启用，设置完成后重启win10

方法二

将以下文本编辑保存为 start_smb_guest.reg ，然后双击运行即可。

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters]
"AllowInsecureGuestAuth"=dword:00000001
