kerberos安装使用[kafka]

安装服务器：yum install krb5-server krb5-libs krb5-auth-dialog

 

修改 /var/kerberos/krb5kdc/kdc.conf, 改 realm 为本身的域

[kdcdefaults]

kdc_ports = 88

kdc_tcp_ports = 88

 

[realms]

YLH.COM = {

#master_key_type = aes256-cts

acl_file = /var/kerberos/krb5kdc/kadm5.acl

dict_file = /usr/share/dict/words

admin_keytab = /var/kerberos/krb5kdc/kadm5.keytab

max_renewable_life = 7d

supported_enctypes = aes256-cts:normal aes128-cts:normal des3-hmac-sha1:normal arcfour-hmac:normal camellia256-cts:normal camellia128-cts:normal des-hmac-sha1:normal des-cbc-md5:normal des-cbc-crc:normal

}

 

修改/etc/krb5.conf

# Configuration snippets may be placed in this directory as well

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]

dns_lookup_realm = false

dns_lookup_kdc = false

ticket_lifetime = 24h

renew_lifetime = 7d

forwardable = true

rdns = false

default_realm = YLH.COM

default_ccache_name = KEYRING:persistent:%{uid}

 

[realms]

YLH.COM = {

kdc = 192.168.1.173

admin_server = 192.168.1.173

}

 

[domain_realm]

.ylh.com = YLH.COM

ylh.com = YLH.COM

 

建立kerberos数据库：/usr/sbin/kdb5_util create -s -r YLH.COM , 保存登录密码

 

添加数据库admin: /usr/sbin/kadmin.local -q "addprinc admin/admin"

 

为admin受权，将文件/var/kerberos/krb5kdc/kadm5.acl的内容编辑为： */admin@YLH.COM

 

centos环境须要覆盖Java jce文件$JAVA_HOME/jre/lib/security

 

 

启动服务器：

service krb5kdc start

service kadmin start

设置开机开启：

chkconfig krb5kdc on

chkconfig kadmin on

 

 

 

安装客户端：yum install krb5-workstation krb5-libs krb5-auth-dialog

配置这些主机上的/etc/krb5.conf，这个文件的内容与KDC中的文件保持一致便可。

 

登录：

在服务器登录：admin.local 。直接登录

在客户端登录: kinit admin/admin 而后输入kadmin命令 。 密码登录

 

建立princ: addprinc test/192.168.1.170@YLH.COM

注意：此处设置的principal信息是针对每台机器设置的，name本身设置，后面的host就是访问kdc的机器host切记

 

生成keytab: xst -k keyname.keytab test/192.168.1.170

 

经过keytab认证： kinit -kt keyname.keytab test/192.168.1.170

 

查看当前的认证用户： klist

 

删除认证缓存：kdestroy
