在CentOS 6.5上安装OpenLDAP并配置LDAP方式用户登录
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

USESMARTCARD=no
USELDAP=yes
USENIS=no
USEKERBEROS=no
USESYSNETAUTH=yes

--------------------------------------------------------------------------------
修改/etc/pam.d/system-auth
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
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
