1、安裝軟件包
安裝必須的工具 bison, make, binutils
下載壓縮包至/usr/local目錄下，並解壓
[root@localhost local]# ls krb5-1.14.tar.gz
krb5-1.14.tar.gz
2、編譯Kerberos
切換目錄至/krb5-1.14/src
在/krb5-1.14/src文件夾下，
運行configure命令
[root@localhost src]# ./configure --prefix=/usr/local/krb5-1.14
執行make命令
[root@localhost src]# make
執行make install
[root@localhost src]# make install
3、IP及域名配置 /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
#::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
127.0.0.1 kerberos.example.com kerberos ldap.example.com
4、配置KDC
a、配置krb5.conf
文件說明：(略)
參數說明：(略)
[root@localhost src]# vi /etc/krb5.conf [logging] default = FILE:/var/log/krb5libs.log kdc = FILE:/var/log/krb5kdc.log admin_server = FILE:/var/log/kadmind.log [libdefaults] default_realm = EXAMPLE.COM dns_lookup_realm = true dns_lookup_kdc = true ticket_lifetime = 24h renew_lifetime = 7d forwardable = true [realms] EXAMPLE.COM = { kdc = kerberos admin_server = kerberos } [domain_realm] .example.com = EXAMPLE.COM example.com = EXAMPLE.COM [kdc] profile = /usr/local/krb5-1.14/var/krb5kdc/kdc.conf |
b、在krb5.conf文件制定位置，創建kdc.conf
[root@localhost krb5kdc]# pwd
/usr/local/krb5-1.14/var/krb5kdc
[root@localhost krb5kdc]# vi kdc.conf
文件說明：(略)
參數說明：(略)
[kdcdefaults] kdc_ports = 88 [realms] EXAMPLE.COM = { profile = /etc/krb5.conf database_name = /usr/local/krb5-1.14/var/krb5kdc/principal admin_database_name = /usr/local/krb5-1.14/var/krb5kdc/kadm5_adb admin_database_lockfile = /usr/local/krb5-1.14/var/krb5kdc/kadm5_adb.lock admin_keytab = FILE:/usr/local/krb5-1.14/var/krb5kdc/kadm5.keytab acl_file = /usr/local/krb5-1.14/var/krb5kdc/kadm5.acl key_stash_file = /usr/local/krb5-1.14/var/krb5kdc/.k5stash kdc_ports = 88 kadmind_port = 749 max_life = 10h 0m 0s max_renewable_life = 7d 0h 0m 0s master_key_type = des-cbc-crc supported_enctypes = des-cbc-crc:normal des:v4 } |
創建Kerberos的本地數據庫
[root@localhost sbin]# ./kdb5_util create -r EXAMPLE.COM -s
Loading random data
Initializing database '/usr/local/krb5-1.14/var/krb5kdc/principal' for realm 'EXAMPLE.COM',
master key name 'K/[email protected]'
You will be prompted for the database Master Password.
It is important that you NOT FORGET this password.
Enter KDC database master key:
Re-enter KDC database master key to verify:
登錄查看kerberos缺省票據
[root@localhost sbin]# ./kadmin.local
Authenticating as principal admin/[email protected] with password.
kadmin.local: listprincs
kadmin/[email protected]
kadmin/[email protected]
kadmin/[email protected]
kiprop/[email protected]
krbtgt/[email protected]
kadmin.local: q
啓動kdc服務
[root@localhost sbin]# ./krb5kdc
5、kadmind配置
5.1本地kadmin.local管理程序提供功能
a、策略管理
策略的增加、刪除、修改、查詢和統計功能；
add_policy, addpol Add policy
modify_policy, modpol Modify policy
delete_policy, delpol Delete policy
get_policy, getpol Get policy
list_policies, listpols, get_policies, getpols List policies
b、個人賬號管理
Principal的增加、刪除、修改、查詢和統計功能；
add_principal, addprinc, ank
Add principal
delete_principal, delprinc
Delete principal
modify_principal, modprinc
Modify principal
change_password, cpw Change password
get_principal, getprinc Get principal
list_principals, listprincs, get_principals, getprincs List principals
get_privs, getprivs Get privileges
c、程序註冊kt管理
Keytable的增加、刪除；
ktadd, xst Add entry(s) to a keytab
ktremove, ktrem Remove entry(s) from a keytab
d、鎖管理
lock Lock database exclusively (use with extreme caution!) unlock Release exclusive database lock
e、程序功能
程序命令幫助和退出程序。
list_requests, lr, ? List available requests. quit, exit, q Exit program.
5.2使用kadmin.local管理程序配置
a、增加管理員賬號
[root@localhost sbin]# ./kadmin.local
kadmin.local: addprinc admin/admin
WARNING: no policy specified for admin/[email protected]; defaulting to no policy
Enter password for principal "admin/[email protected]": admin
Re-enter password for principal "admin/[email protected]": admin
Principal "admin/[email protected]" created.
kadmin.local: listprincs
admin/[email protected]
kadmin/[email protected]
kadmin/[email protected]
kadmin/[email protected]
kiprop/[email protected]
krbtgt/[email protected]
kadmin.local:
b、測試管理員賬號
[root@localhost bin]# ./kinit admin/admin
Password for admin/[email protected]: admin
[root@localhost bin]# ./klist
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: admin/[email protected]
Valid starting Expires Service principal
2016-01-12T14:34:33 2016-01-13T00:34:33 krbtgt/[email protected]
renew until 2016-01-19T14:34:33
c、爲管理員admin/admin指定權限
注：按網上和官方說明kdc.conf中配置 acl_file = /krb5-1.14/var/krb5kdc/kadm5.acl的文件
暫時不知道該文件在哪個步驟生成的
在我以上操作中並沒有生成 kadm5.acl文件，於是手動創建，並添加權限
現在爲管理賬號指定權限，它由文件/usr/local/var/krb5kdc/kadm5.acl中的條目決定。
給賬號admin /admin授予“管理所有委託人”的權限，
通過添加下面這樣一行到/usr/local/var/krb5kdc/kadm5.acl中，並使用通配符實現：
admin/[email protected] *
5.3遠程的kadmin管理程序配置
a、創建一個包含祕鑰的keytab文件
kadmin.local: ktadd -k /usr/local/krb5-1.14/var/krb5kdc/kadm5.keytab kadmin/changepw Entry for principal kadmin/changepw with kvno 2, encryption type des-cbc-crc added to keytab WRFILE:/usr/local/krb5-1.14/var/krb5kdc/kadm5.keytab. |
b、啓動kadmind服務
[root@localhost sbin]# pwd
/usr/local/krb5-1.14/sbin
[root@localhost sbin]# ./kadmind
[root@localhost sbin]# ps -ef | grep kadmind
root 17176 1 0 15:24 ? 00:00:00 ./kadmind
