域主机搭建，windows，linux的加域

一、搭建域主机的好处：
1，简化管理工作。
2，单个帐户登陆后，可以访问域中所有有权访问的资源。
3，具有强大的查询功能。
二、域主机的构建：（windows2012 r2）

这里有详细的配制方法。
三、服务器加域。（我们的dns：10.0.0.8 域ip：test.com）

1. windows服务器加域的方法：
   a:在IPV4属性那里，选Advance->DNS，
   b：DNS Server添加10.0.0.8
   c:Append these DNS suffixes那里添加tcminplay.local
   
   d： System->Advanced system settings->Computere Name
   
   e:点change。修改名字和输入域ip（接下来需要输入域主机的管理员帐号和密码）
   
   f：添加远程登录域账户：System->Advanced system settings->Remote->Select Users ->Add ->Advanced...->输入域管理员用户名和密码 -->Find Now -> 找到 管理员用户 添加
   

2. linux服务器加域的方法：
   a：安装必须的软件包
   yum install krb5-libs krb5-devel pam_krb5 krb5-workstation krb5-auth-dialog
   yum install samba-winbind samba samba-common samba-client samba-winbind-clients
   b：修改三个配置文件
   cat /etc/samba/smb.conf
   [global]
   workgroup = TEST 必须大写
   security = ADS
   idmap uid = 16777216-33554431
   idmap gid = 16777216-33554431
   password server = 10.0.0.8
   map to guest = bad user
   encrypt passwords =yes
   realm = TEST.COM 必须大写
   winbind use default domain = yes
   template homedir = /home/%D/%U
   template shell = /bin/bash
   [homes]
   comment = %S
   path =/home/%D/%S
   writeable = yes
   browsable = yes
   ; valid users = %S
   valid users = CAMPUS\%S

cat /etc/krb5.conf
includedir /etc/krb5.conf.d/
[logging]
default = FILE:/var/log/krb5libs.log
kdc = FILE:/var/log/krb5kdc.log
admin_server = FILE:/var/log/kadmind.log

[libdefaults]
default_realm = TEST.COM 必须大写
dns_lookup_kdc = true
dns_lookup_realm = false
ticket_lifetime = 24h
renew_lifetime = 7d
forwardable = yes
rdns = false
default_ccache_name = KEYRING:persistent:%{uid}
[realms]
TEST.COM = {
kdc = 10.0.0.81:88
admin_server = 10.0.0.8:749
default_domain = TEST.COM 必须大写
}
[domain_realm]
.test.com = TEST.COM 必须大写
test.com = TEST.COM 必须大写

cat /etc/nsswitch.conf
...
passwd: files winbind
shadow: files winbind
group: files winbind 只需要修改这里
...

c:重启samba服务，重启winbind服务。
/bin/systemctl restart samba.service
/bin/systemctl start winbind.service
d：验证 ：
kinit [email protected] 成功会提示输入密码（域主机的管理员密码）
e：加域
net ads join -S 10.0.0.8 -U Administrator
输入密码 无报错则加域成功
