在CentOS 6.5上安装OpenLDAP并配置LDAP方式用户登录

1.安装PHP和apache

如果没有EPEL的源需要安装下

yum install epel-release

若没有下载下来，就创建/etc/yum.repo.d/epel.repo

[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
#baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
failovermethod=priority
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

[epel-debuginfo]
name=Extra Packages for Enterprise Linux 6 - $basearch - Debug
#baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch/debug
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-debug-6&arch=$basearch
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
gpgcheck=1

[epel-source]
name=Extra Packages for Enterprise Linux 6 - $basearch - Source
#baseurl=http://download.fedoraproject.org/pub/epel/6/SRPMS
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-source-6&arch=$basearch
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
gpgcheck=1

phpldapadmin依赖apache和php

yum install php httpd

配置httpd.conf

2.安装OpenLDAP

yum install *openldap* openldap openldap-servers openldap-clients

配置OpenLDAP，配置文件/etc/openldap/slapd.conf

该文件默认没有，从/usr/share/openldap-servers/slapd.conf.obsolete拷贝一份到该位置

owner为ldap:ldap

database monitor
access to *
        by dn.exact="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth" read
        by dn.exact="cn=Manager,dc=iflyyun,dc=cn" read
        by * none

database        bdb
suffix          "dc=iflyyun,dc=cn"
checkpoint      1024 15
rootdn          "cn=Manager,dc=iflyyun,dc=cn"

配置/etc/openldap/ldap.conf

BASE    dc=iflyyun,dc=cn
URI     ldap://bja-pro0002.hadoop.cpcc.iflyyun.cn

配置ldap管理员用户密码

sldappasswd（注意不要用ldappasswd，否则会报GSSAPI错误）

输入密码，获得{SSHA}ph+VRzfWSeamboy0itVlazrJrxzVHh80格式的密码再修改/etc/openldap/slapd.conf

直接使用明文密码，使用加密密码有点问题

配置apache识别index.php

修改/etc/httpd/conf/httpd.conf

找到下面这一行，添加index.php

DirectoryIndex index.html index.html.var  index.php

修改/etc/httpd/conf.d/php.conf

测试OpenLDAP配置文件是否正确：

slaptest -u -f /etc/openldap/slapd.conf 

3.安装phpldapadmin

yum install phpldapadmin 

配置/etc/phpldapadmin/config.ini

$servers->setValue('server','host','192.168.51.211');
$servers->setValue('server','port',389);
$servers->setValue('server','base',array('dc=iflyyun,dc=cn'));
$servers->setValue('login','auth_type','cookie');
$servers->setValue('login','bind_id','cn=Manager,dc=iflyyun,dc=cn');

$servers->setValue('login','attr','dn');（397行，这行取消注释）
// $servers->setValue('login','attr','uid');（将这行注释掉，否则登录会报错）

修改/etc/httpd/conf.d/phpldapadmin.conf，允许从其他机器访问

<Directory /usr/share/phpldapadmin/htdocs>
  Order Deny,Allow
  Allow from all
</Directory>

4.phpldapadmin配置

删除/etc/openldap/lapd.d/目录下的所有文件

创建LDAP根目录

ldapadd -x -D"cn=Manager,dc=iflyyun,dc=cn" -f base.ldif -W

base.ldif

dn: dc=iflyyun,dc=cn
o: ldap
objectclass: dcObject
objectclass: organization

创建管理员用户

# Manager, iflyyun.cn
dn: cn=Manager,dc=iflyyun,dc=cn
objectClass: simpleSecurityObject
objectClass: organizationalRole
cn: Manager
description: LDAP administrator

5.LDAP客户端配置

安装必备软件

yum install nss-pam-ldapd pam_ldap openldap-clients

需要修改的配置文件有：

/etc/sysconfig/authconfig、/etc/pam.d/system-auth、/etc/openldap/ldap.conf、/etc/nssswitch.conf

修改/etc/sysconfig/authconfig

IPADOMAINJOINED=no
USEMKHOMEDIR=yes
USEPAMACCESS=no
CACHECREDENTIALS=yes
USESSSDAUTH=no
USESHADOW=yes
USEWINBIND=no
USEDB=no

FORCELEGACY=no
USEFPRINTD=yes
FORCESMARTCARD=no
PASSWDALGORITHM=yes
USELDAPAUTH=yes
USEPASSWDQC=no
IPAV2NONTP=no
USELOCAUTHORIZE=yes
USECRACKLIB=yes
USEIPAV2=no
USEWINBINDAUTH=no
USESMARTCARD=no
USELDAP=yes
USENIS=no
USEKERBEROS=no
USESYSNETAUTH=yes
USESSSD=no
USEHESIOD=no

修改/etc/pam.d/system-auth

#%PAM-1.0

auth        required      pam_env.so

session     optional   pam_ldap.so

修改/etc/openldap/ldap.conf

#
# LDAP Defaults
#

# See ldap.conf(5) for details
# This file should be world readable but not world writable.

#BASE   dc=example,dc=com
#URI    ldap://ldap.example.com ldap://ldap-master.example.com:666

#SIZELIMIT      12
#TIMELIMIT      15
#DEREF          never

TLS_CACERTDIR /etc/openldap/cacerts

BASE dc=iflyyun,dc=cn
URI ldap://hfa-pro0002.hadoop.cpcc.iflyyun.cn

修改/etc/nssswitch.conf

#
# /etc/nsswitch.conf
#
# An example Name Service Switch config file. This file should be
# sorted with the most-used services at the beginning.
#
# The entry '[NOTFOUND=return]' means that the search for an
# entry should stop if the search in the previous entry turned
# up nothing. Note that if the search failed due to some other reason
# (like no NIS server responding) then the search continues with the
# next entry.
#
# Valid entries include:
#
#       nisplus                 Use NIS+ (NIS version 3)
#       nis                     Use NIS (NIS version 2), also called YP
#       dns                     Use DNS (Domain Name Service)
#       files                   Use the local files
#       db                      Use the local database (.db) files
#       compat                  Use NIS on compat mode
#       hesiod                  Use Hesiod for user lookups
#       [NOTFOUND=return]       Stop searching if not found so far
#

# To use db, put the "db" in front of "files" for entries you want to be
# looked up first in the databases
#
# Example:
#passwd:    db files nisplus nis
#shadow:    db files nisplus nis
#group:     db files nisplus nis

passwd:     files ldap
shadow:     files ldap
group:      files ldap

#hosts:     db files nisplus nis dns
hosts:      files dns

# Example - obey only what nisplus tells us...
#services:   nisplus [NOTFOUND=return] files
#networks:   nisplus [NOTFOUND=return] files
#protocols:  nisplus [NOTFOUND=return] files
#rpc:        nisplus [NOTFOUND=return] files
#ethers:     nisplus [NOTFOUND=return] files
#netmasks:   nisplus [NOTFOUND=return] files     

bootparams: nisplus [NOTFOUND=return] files

ethers:     files
netmasks:   files
networks:   files
protocols:  files
rpc:        files
services:   files

netgroup:   nisplus

publickey:  nisplus

automount:  files nisplus
aliases:    files nisplus

开启名称缓存服务

service nscd restart
