过程 143.1. 安装NIS服务器
-
ypserv
# yum install ypserv -y
-
/etc/hosts
[root@nis ~]# hostname nis.example.com [root@nis ~]# echo "192.168.3.5 nis.example.com" >> /etc/hosts [root@nis ~]# cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 datacenter.example.com datacenter localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 127.0.0.1 kerberos.example.com 192.168.3.5 nis.example.com
-
设置NIS域名
# nisdomainname example.com # nisdomainname example.com
加入 /etc/rc.local 开机脚本
# echo '/bin/nisdomainname example.com' >> /etc/rc.local # echo 'NISDOMAIN=example.com' >> /etc/sysconfig/network
-
设置/etc/ypserv.conf主配置文件
# vim /etc/ypserv.conf 127.0.0.0/255.255.255.0 : * : * : none 192.168.3.0/255.255.255.0 : * : * : none * : * : * : deny
-
创建 /var/yp/securenets 文件
securenets 安全配置文件
# vim /var/yp/securenets host 127.0.0.1 255.255.255.0 192.168.3.0
-
启动NIS服务器
NIS服务器需要portmap服务的支持，并且需要启动ypserv和yppasswdd两个服务
[root@nis ~]# service portmap status portmap (pid 2336) is running... [root@nis ~]# service ypserv start Starting YP server services: [ OK ] [root@nis ~]# service yppasswdd start Starting YP passwd service: [ OK ]
-
构建NIS数据库
32bit: /usr/lib/yp/ypinit -m
64bit: /usr/lib64/yp/ypinit -m
[root@nis ~]# /usr/lib64/yp/ypinit -m At this point, we have to construct a list of the hosts which will run NIS servers. nis.example.com is in the list of NIS server hosts. Please continue to add the names for the other hosts, one per line. When you are done with the list, type a <control D>. next host to add: nis.example.com next host to add: next host to add: The current list of NIS servers looks like this: nis.example.com Is this correct? [y/n: y] We need a few minutes to build the databases... Building /var/yp/example.com/ypservers... Running /var/yp/Makefile... gmake[1]: Entering directory `/var/yp/example.com' Updating passwd.byname... Updating passwd.byuid... Updating group.byname... Updating group.bygid... Updating hosts.byname... Updating hosts.byaddr... Updating rpc.byname... Updating rpc.bynumber... Updating services.byname... Updating services.byservicename... Updating netid.byname... Updating protocols.bynumber... Updating protocols.byname... Updating mail.aliases... gmake[1]: Leaving directory `/var/yp/example.com' nis.example.com has been set up as a NIS master server. Now you can run ypinit -s nis.example.com on all slave server.检查
# ls /var/yp/ binding example.com Makefile nicknames securenets ypservers
-
Service
[root@datacenter ~]# chkconfig --list | grep yp ypbind 0:off 1:off 2:off 3:off 4:off 5:off 6:off yppasswdd 0:off 1:off 2:off 3:off 4:off 5:off 6:off ypserv 0:off 1:off 2:off 3:off 4:off 5:off 6:off ypxfrd 0:off 1:off 2:off 3:off 4:off 5:off 6:off [root@nis ~]# chkconfig ypserv on [root@nis ~]# chkconfig yppasswdd on
Now you can run ypinit -s nis.example.com on all slave server.
# ypinit -s nis.example.com
过程 143.2. 安装NIS客户端软件
-
NIS客户机需要安装ypbind和yp-tools两个软件包
# yum install ypbind yp-tools -y
-
NIS域名
# nisdomainname example.com
-
/etc/hosts
192.168.3.5 nis.example.com
-
/etc/yp.conf
# vim /etc/yp.conf domain example.com server nis.example.com
-
/etc/nsswitch.conf
# vim /etc/nsswitch.conf passwd: files nis shadow: files nis group: files nis hosts: files nis dns
-
启动ypbind服务程序
[root@test ~]# service portmap status portmap is stopped [root@test ~]# service portmap start Starting portmap: [ OK ] [root@test ~]# service ypbind start Turning on allow_ypbind SELinux boolean Binding to the NIS domain: [ OK ] Listening for an NIS domain server..
-
yp-tools 测试工具
yptest 命令可对NIS服务器进行自动测试
# yptest
ypwhich 命令可显示NIS客户机所使用的NIS服务器的主机名称和数据库文件列表
# ypwhich # ypwhich -x
ypcat命令显示数据库文件列表和指定数据库的内容
# ypcat -x # ypcat passwd
-
NIS Client Service
# chkconfig ypbind on
# authconfig-tui

在NIS服务器上创建一个test用户
# adduser test # passwd test # /usr/lib64/yp/ypinit -m
nis client
使用test用户登录到客户机
ssh test@client.example.com

-
First, install the OpenLDAP server daemon slapd and ldap-utils, a package containing LDAP management utilities:
sudo apt-get install slapd ldap-utils
By default the directory suffix will match the domain name of the server. For example, if the machine's Fully Qualified Domain Name (FQDN) is ldap.example.com, the default suffix will be dc=example,dc=com. If you require a different suffix, the directory can be reconfigured using dpkg-reconfigure. Enter the following in a terminal prompt:
sudo dpkg-reconfigure slapd
-
example.com.ldif
dn: ou=people,dc=example,dc=com objectClass: organizationalUnit ou: people dn: ou=groups,dc=example,dc=com objectClass: organizationalUnit ou: groups dn: uid=john,ou=people,dc=example,dc=com objectClass: inetOrgPerson objectClass: posixAccount objectClass: shadowAccount uid: john sn: Doe givenName: John cn: John Doe displayName: John Doe uidNumber: 1000 gidNumber: 10000 userPassword: password gecos: John Doe loginShell: /bin/bash homeDirectory: /home/john shadowExpire: -1 shadowFlag: 0 shadowWarning: 7 shadowMin: 8 shadowMax: 999999 shadowLastChange: 10877 mail: john.doe@example.com postalCode: 31000 l: Toulouse o: Example mobile: +33 (0)6 xx xx xx xx homePhone: +33 (0)5 xx xx xx xx title: System Administrator postalAddress: initials: JD dn: cn=example,ou=groups,dc=example,dc=com objectClass: posixGroup cn: example gidNumber: 10000
-
To add the entries to the LDAP directory use the ldapadd utility:
ldapadd -x -D cn=admin,dc=example,dc=com -W -f example.com.ldif
We can check that the content has been correctly added with the tools from the ldap-utils package. In order to execute a search of the LDAP directory:
ldapsearch -xLLL -b "dc=example,dc=com" uid=john sn givenName cn dn: uid=john,ou=people,dc=example,dc=com cn: John Doe sn: Doe givenName: John
Just a quick explanation:
-x: will not use SASL authentication method, which is the default.
-LLL: disable printing LDIF schema information.
-
libnss-ldap
sudo apt-get install libnss-ldap
-
reconfigure ldap-auth-config
sudo dpkg-reconfigure ldap-auth-config
-
auth-client-config
sudo auth-client-config -t nss -p lac_ldap
-
pam-auth-update.
sudo pam-auth-update
sudo apt-get install ldapscripts
/etc/ldapscripts/ldapscripts.conf
SERVER=localhost BINDDN='cn=admin,dc=example,dc=com' BINDPWDFILE="/etc/ldapscripts/ldapscripts.passwd" SUFFIX='dc=example,dc=com' GSUFFIX='ou=Groups' USUFFIX='ou=People' MSUFFIX='ou=Computers' GIDSTART=10000 UIDSTART=10000 MIDSTART=10000
Now, create the ldapscripts.passwd file to allow authenticated access to the directory:
sudo sh -c "echo -n 'secret' > /etc/ldapscripts/ldapscripts.passwd" sudo chmod 400 /etc/ldapscripts/ldapscripts.passwd
http://web.mit.edu/Kerberos/
kerberos是由MIT开发的提供网络认证服务的系统，很早就听说过它的大名，但一直没有使用过它。 它可用来为网络上的各种server提供认证服务,使得口令不再是以明文方式在网络上传输，并且联接之间通讯是加密的； 它和PKI认证的原理不一样，PKI使用公钥体制(不对称密码体制)，kerberos基于私钥体制(对称密码体制)。

默认你只能通过localhost访问radius, 如需其他网络访问需要在配置文件中添加类似下面配置，配置文件在 /etc/freeradius/clients.conf
# vim /etc/freeradius/clients.conf
client 172.16.0.0/24 {
secret = testing123
shortname = freeradius.example.com
}
CentOS与Ubuntu安装包有所不同，配置文件在 /etc/raddb下面
