===========================服务端===========================
1、安装
安装DB
[root@localhost openldap]# yum install -y libtool-ltdl-devel.x86_64 libtool-ltdl.x86_64 [root@localhost tarbag]#tar -xzvf db-4.8.26.tar.gz -C ../software/ [root@localhost tarbag]# cd ../software/db-4.8.26/build_unix/ [root@localhost build_unix]# ../dist/configure [root@localhost build_unix]#make install [root@localhost build_unix]#echo "/usr/local/BerkeleyDB.4.8/lib/" >> /etc/ld.so.conf [root@localhost build_unix]#ldconfig -vv
安装openldap
[root@localhost tarbag]#tar zxvf openldap-2.4.21.tgz -C ../software/ [root@localhost tarbag]# cd ../software/openldap-2.4.21/ [root@localhost openldap-2.4.21]# ./configure --prefix=/usr/local/openldap-2.4.21 --enable-syslog --enable-modules --with-tls CPPFLAGS=-I/usr/local/BerkeleyDB.4.8/include/ LDFLAGS=-L/usr/local/BerkeleyDB.4.8/lib/ [root@localhost openldap-2.4.21]#make depend [root@localhost openldap-2.4.21]#make [root@localhost openldap-2.4.21]#make test 这个需要比较长的时间.如果觉得没必要执行这一步的可以跳过.直接make install [root@localhost openldap-2.4.21]#make install [root@localhost openldap-2.4.21]# cd /usr/local/openldap-2.4.21/ [root@localhost openldap-2.4.21]# ls bin etc include lib libexec sbin share var
2、openldap配置
下载openssh-lpk_openldap.schema
[root@localhost ~]# cd /usr/local/openldap-2.4.21/etc/openldap/schema [root@localhost schema]#wget http://openssh-lpk.googlecode.com/files/openssh-lpk_openldap.schema [root@localhost schema]#cp openssh-lpk_openldap.schema openssh-lpk.schema
生成密码:
[root@localhost ~]# cd /usr/local/openldap-2.4.21/sbin/
[root@localhost sbin]# ./slappasswd
New password:
Re-enter new password:
{SSHA}o/pZaQlZohhssEC7UAWnqWZ3GaHwxeUZ 密码是123456 这个密码写到slapd.conf里面的rootpw位置配置slapd.conf
[root@localhost openldap]# cat /usr/local/openldap-2.4.21/etc/openldap/slapd.conf
include /usr/local/openldap-2.4.21/etc/openldap/schema/core.schema

[root@localhost openldap]#cd /usr/local/openldap-2.4.21/etc/openldap
拷贝DB_CONFIG到Ldap数据目录.
[root@localhost openldap]# cp DB_CONFIG.example /opt/openldap_data/
修改syslog.conf
[root@localhost www]# vi /etc/syslog.conf #Save ldap messages to ldap.log local4.* /var/log/ldap.log
重启syslog
[root@localhost openldap]# service syslog restart Shutting down kernel logger: [ OK ] Shutting down system logger: [ OK ] Starting system logger: [ OK ] Starting kernel logger: [ OK ]
启动ldap
启动方法1：
# /usr/local/openldap-2.4.21/libexec/slapd # 直接进入后台工作
启动方法2：
# /usr/local/openldap-2.4.21/libexec/slapd -d 256 # 依旧在前端,有debug信息
[root@localhost run]# /usr/local/openldap-2.4.21/libexec/slapd [root@localhost run]# netstat -lntp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:389 0.0.0.0:* LISTEN 22917/slapd tcp 0 0 :::389 :::* LISTEN 22917/slapd tcp 0 0 :::22 :::* LISTEN 1987/sshd
3、生成公私密钥对（任何一台机器都行）
# ssh-keygen -t rsa .....不断回车 # cd /root/.ssh/ # sz id_rsa.pub 公钥（导入ldap的sshPublicKey字段） # sz id_rsa 私钥（放在crt,putty,linux的/root/.ssh/下）
4、导入ldap数据
根：
[root@localhost ~]# cat passwd.ldif #version: 1 dn: dc=hsf,dc=com objectClass: top objectClass: domain dc: hsf dn: ou=groups,dc=hsf,dc=com objectClass: top objectClass: organizationalUnit ou: groups dn: cn=root,ou=groups,dc=hsf,dc=com objectClass: posixGroup objectClass: top cn: root gidNumber: 0 memberUid: root dn: ou=users,dc=hsf,dc=com objectClass: organizationalPerson objectClass: person objectClass: top cn: users sn: users ou: users dn: uid=root,ou=users,dc=hsf,dc=com objectClass: organizationalPerson objectClass: person objectClass: top objectClass: ldapPublicKey objectClass: posixAccount cn: root gidNumber: 0 homeDirectory: /root/ sn: root uid: root uidNumber: 0 sshPublicKey: ssh-rsa testAAgQDl+WA5jQja/BDfBSwo3dJ78uaaaaaILbNEEbHGqbXXL74S2HUHkGJ5UH1RHd9AzH1bzgEfP3CU7wHeghG5co576xRUrZw5BolybBz+3q1GxRfqfoZGxZP6/fyYogSrjaR+pT3MxBx91vt+OK61uBhuOCzIe8gDOpxAeZP6SRAJw== hsf@www.hsf.com [root@localhost openldap]# /usr/local/openldap-2.4.21/bin/ldapadd -x -D "cn=Manager,dc=hsf,dc=com" -W -f passwd.ldif
====================客户端====================
IP地址：192.168.100.153
1、安装openssh补丁包:
[root@localhost tarbag]# gunzip openssh-lpk-5.9p1-0.3.14.patch.gz [root@localhost tarbag]# tar zxvf openssh-5.9p1.tar.tar [root@localhost tarbag]# cd openssh-5.9p1 [root@localhost openssh-5.9p1]# patch -Np1 -i /usr/local/src/tarbag/openssh-lpk-5.9p1-0.3.14.patch patching file auth2-pubkey.c patching file auth-rsa.c patching file config.h.in patching file configure.ac patching file ldapauth.c patching file ldapauth.h patching file lpk-user-example.txt patching file Makefile.in patching file openssh-lpk_openldap.schema patching file openssh-lpk_sun.schema patching file README.lpk patching file servconf.c patching file servconf.h patching file sshd.c patching file sshd_config patching file sshd_config.5 patching file version.h [root@localhost tarbag]#./configure \ --prefix=/usr \ --sysconfdir=/etc/ssh \ --libexecdir=/usr/sbin \ --with-md5-passwords \ --with-pam \ --with-libs="-lldap" \ --with-cppflags="-DWITH_LDAP_PUBKEY" \ [root@localhost tarbag]#make [root@localhost tarbag]#make install
2、修改sshd配置文件
# cat /etc/ssh/sshd_config | grep -v '#' | grep -v '^$'
SyslogFacility AUTHPRIV
PasswordAuthentication no
UsePAM no
X11Forwarding yes
Subsystem sftp /usr/libexec/openssh/sftp-server
UseLPK yes
LpkServers ldap://192.168.100.151:389
LpkUserDN ou=users,dc=hsf,dc=com
LpkGroupDN ou=groups,dc=hsf,dc=com
LpkBindDN cn=Manager,dc=hsf,dc=com
LpkBindPw {SSHA}o/pZaQlZohhssEC7UAWnqWZ3GaHwxeUZ
LpkForceTLS no
LpkSearchTimelimit 3
LpkBindTimelimit 3修改:nsswitch.conf
[root@localhost openssh-5.9p1]# vi /etc/nsswitch.conf passwd: files ldap shadow: files ldap group: files ldap
修改authconfig
[root@localhost etc]# cat /etc/sysconfig/authconfig | grep yes USELDAPAUTH=yes USESHADOW=yes USELOCAUTHORIZE=yes USELDAP=yes USECRACKLIB=yes
3、重启sshd
# service sshd restart
4、增加文件
[root@localhost etc]#vi /etc/pam.d/common-session session required pam_unix.so session required pam_mkhomedir.so skel=/etc/skel/ session optional pam_ldap.so
===========================Autofs配置===========================
(也可以用ldap里面的auto.schema来配置.我觉得没有这个来得方便.)
ldap 共享家目录 client使用autofs自动挂载对应的家目录 做这个是解决Could not chdir to home directory /home/hsf: No such file or directory
ldap nfs配置:
[root@localhost home]# cat /etc/exports /home 192.168.100.0/255.255.255.0(rw,async,wdelay,root_squash,no_subtree_check,anonuid=65534,anongid=65534) [root@localhost home]# service portmap start [root@localhost home]# service nfs start [root@localhost home]# chkconfig nfs on [root@localhost home]# chkconfig portmap on
client配置:
[root@localhost ~]# cat /etc/auto.master # /home /etc/auto.nfs --timeout=100 [root@localhost ~]# cat /etc/auto.nfs * 192.168.100.151:/home/& [root@localhost ~]# service autofs start [root@localhost ~]# service portmap start
测试client端:
[root@localhost ~]# cd /home/ [root@localhost home]# ls [root@localhost home]# [root@localhost home]# su - test -sh-3.00$ pwd /home/test/ -sh-3.00$
===================Ldap+sudoers配置=================:
先添加sudoer.schema配置
[root@localhost log]#vi /etc/openldap/schema/sudoer.schema attributetype ( 1.3.6.1.4.1.15953.9.1.1 NAME 'sudoUser' DESC 'User(s) who may run sudo' EQUALITY caseExactIA5Match SUBSTR caseExactIA5SubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 ) attributetype ( 1.3.6.1.4.1.15953.9.1.2 NAME 'sudoHost' DESC 'Host(s) who may run sudo' EQUALITY caseExactIA5Match SUBSTR caseExactIA5SubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 ) attributetype ( 1.3.6.1.4.1.15953.9.1.3 NAME 'sudoCommand' DESC 'Command(s) to be executed by sudo' EQUALITY caseExactIA5Match SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 ) attributetype ( 1.3.6.1.4.1.15953.9.1.4 NAME 'sudoRunAs' DESC 'User(s) impersonated by sudo' EQUALITY caseExactIA5Match SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 ) attributetype ( 1.3.6.1.4.1.15953.9.1.5 NAME 'sudoOption' DESC 'Options(s) followed by sudo' EQUALITY caseExactIA5Match SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 ) attributetype ( 1.3.6.1.4.1.15953.9.1.6 NAME 'sudoRunAsUser' DESC 'User(s) impersonated by sudo' EQUALITY caseExactIA5Match SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 ) attributetype ( 1.3.6.1.4.1.15953.9.1.7 NAME 'sudoRunAsGroup' DESC 'Group(s) impersonated by sudo' EQUALITY caseExactIA5Match SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 ) attributetype ( 1.3.6.1.4.1.15953.9.1.8 NAME 'sudoNotBefore' DESC 'Start of time interval for which the entry is valid' EQUALITY generalizedTimeMatch ORDERING generalizedTimeOrderingMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.24 ) attributetype ( 1.3.6.1.4.1.15953.9.1.9 NAME 'sudoNotAfter' DESC 'End of time interval for which the entry is valid' EQUALITY generalizedTimeMatch ORDERING generalizedTimeOrderingMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.24 ) attributeTypes ( 1.3.6.1.4.1.15953.9.1.10 NAME 'sudoOrder' DESC 'an integer to order the sudoRole entries' EQUALITY integerMatch ORDERING integerOrderingMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 ) objectclass ( 1.3.6.1.4.1.15953.9.2.1 NAME 'sudoRole' SUP top STRUCTURAL DESC 'Sudoer Entries' MUST ( cn ) MAY ( sudoUser $ sudoHost $ sudoCommand $ sudoRunAs $ sudoRunAsUser $ sudoRunAsGroup $ sudoOption $ sudoNotBefore $ sudoNotAfter $ sudoOrder $ description $ou ) )
将这个sudoer.schema加到slapd.conf中
[root@localhost log]# cat /etc/openldap/slapd.conf | grep sudo include /etc/openldap/schema/sudoer.schema
sudoer默认Ldif数据.
[root@localhost ~]# cat sudo.ldif dn: ou=SUDOers,dc=hsf,dc=com objectClass: top objectClass: organizationalUnit description: SUDO Configuration Subtree ou: SUDOers dn: cn=defaults,ou=SUDOers,dc=hsf,dc=com objectClass: top objectClass: sudoRole cn: defaults description: Default sudoOption's go here sudoOption: requiretty sudoOption: !visiblepw sudoOption: env_reset dn: cn=root,ou=SUDOers,dc=hsf,dc=com objectClass: top objectClass: sudoRole cn: root sudoUser: root sudoHost: ALL sudoRunAsUser: ALL sudoCommand: ALL dn: cn=%wheel,ou=SUDOers,dc=hsf,dc=com objectClass: top objectClass: sudoRole cn: %wheel sudoUser: %wheel sudoHost: ALL sudoRunAsUser: ALL sudoCommand: ALL sudoOption: !authenticate dn: cn=hsf,ou=SUDOers,dc=hsf,dc=com objectClass: top objectClass: sudoRole cn: hsf sudoUser: hsf sudoHost: ALL sudoRunAsUser: ALL sudoCommand: ALL sudoOption: !authenticate
导入sudo数据到Ldap中.
[root@localhost ~]# ldapadd -x -D "cn=Manager,dc=hsf,dc=com" -W -f sudo.ldif
====================sudo client配置==================:
安装sudo: (默认安装的sudo不支持ldap)

修改客户端/etc/openldap/ldap.conf
[root@localhost etc]# vi ldap.conf TLS_CACERT /etc/openldap/cacerts/cacert.pem
重启客户端sshd
[root@localhost etc]# service sshd restart Stopping sshd: [ OK ] Starting sshd: [ OK ]
查看ldap服务器日志:
conn=1004 fd=14 ACCEPT from IP=192.168.100.153:58390 (IP=0.0.0.0:389) conn=1004 op=0 EXT oid=1.3.6.1.4.1.1466.20037 conn=1004 op=0 STARTTLS conn=1004 op=0 RESULT oid= err=0 text= conn=1004 fd=14 TLS established tls_ssf=256 ssf=256 conn=1004 op=1 BIND dn="cn=Manager,dc=hsf,dc=com" method=128 conn=1004 op=1 BIND dn="cn=Manager,dc=hsf,dc=com" mech=SIMPLE ssf=0 conn=1004 op=1 RESULT tag=97 err=0 text= 出现STARTTLS为 OK
配置ldap node2证书
将前面生成的cacert.pem newcert.pem newreq.pem抟到从服务器对应的位置上.修改权限
修改下slapd.conf 重启Ldap服务即可.
配置主主Ldap时.客户机配置需要增加两台主主的IP:
[root@localhost etc]# cat /etc/ldap.conf | grep -v '#' | grep -v '^$' host 192.168.100.151 192.168.100.152 URI ldap://192.168.100.151 ldap://192.168.100.152 BASE dc=hsf,dc=com SUDOERS_BASE ou=SUDOers,dc=hsf,dc=com pam_password md5 [root@localhost etc]# cat /etc/openldap/ldap.conf | grep -v '#' | grep -v '^$' TIMELIMIT 30 BIND_TIMELIMT 30 BASE dc=hsf,dc=com SUDOERS_BASE ou=SUDOers,dc=hsf,dc=com TLS_CACERT /etc/openldap/cacerts/cacert.pem
重启client sshd
基于openldap+openssh-lpk+sudo+tls用户验证管理完成.
