CentOS 7 是自带的firewall，CentOS 6 好像是iptables。关闭防火墙命令如下：

     第一种方法是关闭防火墙：

        systemctl disable firewalld.service

    第二种方法是添加规则：

        firewall-cmd --permanent --zone=public --add-service=samba
        firewall-cmd --reload

2、关闭selinux

    vim /etc/selinux/config
    设置：SELINUX=disabled

1、安装

yum install samba samba-client samba-common -y

2、配置

备份已有配置
mv /etc/samba/smb.conf /etc/samba/smb.conf.bkp
添加新的配置
vim /etc/samba/smb.conf
输入以下内容
[global]
workgroup = WORKGROUP
server string = Samba Server %v
netbios name = centos
security = user
map to guest = bad user
dns proxy = no
#============================ Share Definitions ============================== 
[Public]
path = /data/share/
writable = yes
browsable = yes
guest ok = yes
guest only = yes
create mode = 0777
directory mode = 0777


注意：在samba4中 share 和 server已经被禁用，需要用 security = user 和map to guest =Bad User来实现无密码访问目录




配置启动服务
mkdir -p /data/share/public
systemctl enable smb.service
systemctl enable nmb.service
systemctl restart smb.service
systemctl restart nmb.service


设置防火墙
firewall-cmd --permanent --zone=public --add-service=samba
firewall-cmd --reload
修改目录访问权限 
chmod -R 0777  /data/share/public
chown -R nobody:nobody  /data/share/public

WINDOWS输入\centos 访问
