Samba（Server Messages Block）是一种linux系统和windws系统之间依靠网络协议共享文件的服务程序，（Samba has provided secure, stable and fast file and print services for all clients using the SMB/CIFS protocol ），下面简单介绍在Centos 7部署记录（IP：192.168.1.19）
一、安装Samba
[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)
[root@localhost ~]# yum install -y samba
二、配置防火墙和Selinux，否则windows无法访问，在生产环境一般防火墙都不会关闭
[root@localhost ~]# systemctl status firewalld #一般情况下默认是开的，如果关闭，就启动一下

Hint: Some lines were ellipsized, use -l to show in full. [root@localhost ~]# firewall-cmd --add-service samba --permanent
success [root@localhost ~]# firewall-cmd --reload #重启防火墙
success [root@localhost ~]# firewall-cmd --list-all|grep samba #确认是否加策略成功
services: ssh dhcpv6-client samba 关闭Selinux，否则windows客户端连接不上samba
[root@localhost ~]# vim /etc/selinux/config
SELINUX=disabled [root@localhost ~]# setenforce 0
[root@localhost ~]# getenforce
Permissive
三、Samba服务器的配置
[root@localhost samba]# cp /etc/samba/smb.conf /etc/samba/smb.conf_bak_20190426
[root@localhost samba]# cat /etc/samba/smb.conf
[global] #全局配置
workgroup = SAMBA
security = user #安全验证的方式
#1、share 来访主机无需验证口令，比较方便，但是安全性较差，现在新版本限制使用，如果使用无法启动服务
#2、user 需要验证来访主机提供的口令才能访问
#3、使用独立的远程主机验证来验证提供的口令
#4、domain使用域控制器进行身份验证
passdb backend = tdbsam printing = cups
printcap name = cups
load printers = yes
cups options = raw [homes]
comment = Home Directories
valid users = %S, %D%w%S
browseable = No
read only = No
inherit acls = Yes [printers]
comment = All Printers
path = /var/tmp
printable = Yes
create mask = 0600
browseable = No [print$]
comment = Printer Drivers
path = /var/lib/samba/drivers
write list = @printadmin root
force group = @printadmin
create mask = 0664
directory mask = 0775
[database] #共享名称，也是文件夹的标识，配置了多少个，登陆的时候就会显示多少文件夹
comment=do not modify it all will #对该共享的描述，随意自己定义
path=/home/database #该共享的路径
public=no #是否对所有人共享
writeable=yes #允许写入操作
！！！如果是拷贝配置的话，去掉汉字，否则smb服务无法启动 [root@localhost samba]# systemctl restart smb
4、访问方式一、任何人都可以匿名访问，可以增删改查
[root@localhost home]# chmod 777 database/ [root@localhost database]# vim /etc/samba/smb.conf
[global]
workgroup = SAMBA
security = user
map to guest = Bad User
passdb backend = tdbsam printing = cups
printcap name = cups
load printers = yes
cups options = raw [homes]
comment = Home Directories
valid users = %S, %D%w%S
browseable = No
read only = No
inherit acls = Yes [printers]
comment = All Printers
path = /var/tmp
printable = Yes
create mask = 0600
browseable = No [print$]
comment = Printer Drivers
path = /var/lib/samba/drivers
write list = @printadmin root
force group = @printadmin
create mask = 0664
directory mask = 0775
[database]
comment=do not modify it all will
path=/home/database
public = yes
writeable=yes
guest ok = yes
这中方法谨慎使用，因为存在很大的安全因素，如果别人不小心删除或者修改文件，我们就无法恢复了。
有的时候通过IP访问，时间久了或者其他原因很容易忘记，这时候配一个内网的DNS能够有效的解决这个二问题，下面演示如何配置DNS访问我们的服务器
1、先给服务器配置上DNS解析，假如用开发组来命名
[root@localhost ~]# vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.1.19 devops
~
[root@localhost ~]# ping -c 4 devops
PING devops (192.168.1.19) 56(84) bytes of data.
64 bytes from devops (192.168.1.19): icmp_seq=1 ttl=64 time=0.045 ms
64 bytes from devops (192.168.1.19): icmp_seq=2 ttl=64 time=0.122 ms
64 bytes from devops (192.168.1.19): icmp_seq=3 ttl=64 time=0.125 ms
64 bytes from devops (192.168.1.19): icmp_seq=4 ttl=64 time=0.121 ms --- devops ping statistics ---
4 packets transmitted, 4 received, 0% packet loss, time 3008ms
rtt min/avg/max/mdev = 0.045/0.103/0.125/0.034 ms 测试内网是没有问题，然后配置windows的hosts C:\Windows\System32\drivers\etc #我的电脑是在这个路径下 127.0.0.1 localhost
192.168.1.19 devops #加上这个配置
测试OK，我们就可以通过 \\devops 去访问我们的服务器
访问方式二、通过账号密码访问，在Centos7中，Samba服务默认的用户认证模式（user）
但是只有建立信息数据库之后才能使用用户口令认证模式，
pdbedit命令用于管理SMB服务程序的账户信息数据库，语法格式为 pdbedit [选项] 账户
| -a -u 用户名 | 建立samba账户 |
| -x -u 用户名 | 删除samba账户 |
| -L | 列出账户列表 |
| -Lv | 列出账户详细信息的列表 |
这里我们通过root去访问，那你也可以用其他账号去访问
[root@localhost ~]# id root
uid=0(root) gid=0(root) groups=0(root) [root@localhost ~]# pdbedit -a -u root
new password:
retype new password:
Unix username: root
NT username:
Account Flags: [U ]
User SID: S-1-5-21-683895756-2385326933-4243325015-1000
Primary Group SID: S-1-5-21-683895756-2385326933-4243325015-513
Full Name: root
Home Directory: \\localhost\root
HomeDir Drive:
Logon Script:
Profile Path: \\localhost\root\profile
Domain: LOCALHOST
Account desc:
Workstations:
Munged dial:
Logon time: 0
Logoff time: Wed, 06 Feb 2036 10:06:39 EST
Kickoff time: Wed, 06 Feb 2036 10:06:39 EST
Password last set: Mon, 08 Apr 2019 16:51:45 EDT
Password can change: Mon, 08 Apr 2019 16:51:45 EDT
Password must change: never
Last bad password : 0
Bad password count : 0
Logon hours : FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
在使用用户名密码访问时，需将全局配置里面map to guest注释掉
# map to guest = Bad User
[root@localhost ~]# systemctl restart smb
