1、关闭防火墙。
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
Centos7配置文件共享服务器SAMBA三步曲
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 0755 public
chown -R nobody:nobody public
关闭selinux，这里不做描述了
3、试用
windows里在运行里输入:\ip address (如图)
即可访问(如果显示没有访问权限, 则试一下重新启动Centos 7)
