1、關閉防火牆。
CentOS 7 是自帶的firewall，CentOS 6 好像是iptables。關閉防火牆命令如下：
第一種方法是關閉防火牆：
systemctl disable firewalld.service
第二種方法是添加規則：
firewall-cmd --permanent --zone=public --add-service=samba
firewall-cmd --reload
2、關閉selinux
vim /etc/selinux/config
設置：SELINUX=disabled
1、安裝
yum install samba samba-client samba-common -y
2、配置
備份已有配置
mv /etc/samba/smb.conf /etc/samba/smb.conf.bkp
添加新的配置
vim /etc/samba/smb.conf
輸入以下內容
[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已經被禁用，需要用 security = user 和map to guest =Bad User來實現無密碼訪問目錄
配置啟動服務
mkdir -p /data/share/public
systemctl enable smb.service
systemctl enable nmb.service
systemctl restart smb.service
systemctl restart nmb.service
設置防火牆
firewall-cmd --permanent --zone=public --add-service=samba
firewall-cmd --reload
修改目錄訪問權限
chmod -R 0777 /data/share/public
chown -R nobody:nobody /data/share/public
WINDOWS輸入\\centos 訪問
