kerberos服务器端

1.安装tcl

	wget http://downloads.sourceforge.net/project/tcl/Tcl/8.5.12/tcl8.5.12-src.tar.gz
	tar zvxf tcl8.5.12-src.tar.gz
	cd tcl8.5.12
	cd unix
	./configure
	make
	make install

2, 下载
http://web.mit.edu/kerberos/dist/krb5/1.10/krb5-1.10.3-signed.tar

3.解压

	tar xvf krb5-1.10.3-signed.tar
	tar zvxf krb5-1.10.3.tar.gz
	cd krb5-1.10.3

3.编译

	./configure --enable-dns-for-realm --with-tcl=/usr/local/lib/tcl8.5
	增加对dns 和tcl支持。
	make
	make check
        make install

4.时间校对
       crontab中配置时间校对（服务端、客户端时间不一致无法连接）

0-59/10 * * * * /usr/sbin/ntpdate us.pool.ntp.org

5，配置/etc/krb5.conf文件

[logging]
	default = FILE:/var/log/krb5libs.log
	kdc = FILE:/var/log/krb5kdc.log
	admin_server = FILE:/var/log/kadmind.log

[libdefaults]
	default_realm = DEVAPP.COM
	dns_lookup_realm = false
	dns_lookup_kdc = false
	ticket_lifetime = 24h
	forwardable = yes

[realms]
	DEVAPP.COM = {
	kdc = kerberos.devapp.com:88
	admin_server = kerberos.devapp.com:749
	default_domain = devapp.com
 }

[domain_realm]
	.devapp.com = DEVAPP.COM
	devapp.com = DEVAPP.COM

[appdefaults]
 pam = {
   debug = false
   ticket_lifetime = 36000
   renew_lifetime = 36000
   forwardable = true
   krb4_convert = false
 }
 
[kdc]  
    profile=/usr/local/var/krb5kdc/kdc.conf

6.配置/usr/local/var/krb5kdc/kdc.conf
可以从/usr/local/share/examples/krb5/kdc.conf 复制一份。

[kdcdefaults]
kdc_ports = 750,88

[realms]
DEVAPP.COM = {
       database_name = /usr/local/var/krb5kdc/principal
       admin_keytab = /usr/local/var/krb5kdc/kadm5.keytab 
       acl_file = /usr/local/var/krb5kdc/kadm5.acl
       key_stash_file = /usr/local/var/krb5kdc/.k5.DEVAPP.COM
       kdc_ports = 750,88
       max_life = 10h 0m 0s
       max_renewable_life = 7d 0h 0m 0s
}

7，创建数据库

/usr/local/sbin/kdb5_util create -r DEVAPP.COM -s

系统添加用户useradd devk
1）kadmin.local 中查看用户

listprincs

2）kadmin.local 中添加用户

addprinc [e-mail]

8，重启krb5kdc和kadmind进程

/usr/local/sbin/kadmind 
/usr/local/sbin/krb5kdc 

9，配置服务端/etc/hosts

#本机的KDC服务hosts
192.168.0.102 devapp.com kerberos.devapp.com
#客户机的hosts
192.168.0.103 103.devapp.com
