centos7下ldap服務搭建

1、安裝ldap服務

#!/bin/bash
echo "install ldap rpm"
yum install -y openldap-servers openldap-clients
cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG
chown ldap. /var/lib/ldap/DB_CONFIG
systemctl start slapd
systemctl enable slapd

2、配置ldap服務

# generate encrypted password
[root@dlp ~]# slappasswd 
New password:
Re-enter new password:
{SSHA}xxxxxxxxxxxxxxxxxxxxxxxx
[root@dlp ~]# vi chrootpw.ldif
# specify the password generated above for "olcRootPW" section
dn: olcDatabase={0}config,cn=config
changetype: modify
add: olcRootPW
olcRootPW: {SSHA}xxxxxxxxxxxxxxxxxxxxxxxx

[root@dlp ~]# ldapadd -Y EXTERNAL -H ldapi:/// -f chrootpw.ldif 
SASL/EXTERNAL authentication started
SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth
SASL SSF: 0
modifying entry "olcDatabase={0}config,cn=config"

匯入基本模式

[root@dlp ~]# ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/openldap/schema/cosine.ldif 
SASL/EXTERNAL authentication started
SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth
SASL SSF: 0
adding new entry "cn=cosine,cn=schema,cn=config"

[root@dlp ~]# ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/openldap/schema/nis.ldif 
SASL/EXTERNAL authentication started
SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth
SASL SSF: 0
adding new entry "cn=nis,cn=schema,cn=config"

[root@dlp ~]# ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/openldap/schema/inetorgperson.ldif 
SASL/EXTERNAL authentication started
SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth
SASL SSF: 0
adding new entry "cn=inetorgperson,cn=schema,cn=config"

在ldap的DB中設定域名

# generate directory manager's password
[root@dlp ~]# slappasswd 
New password:
Re-enter new password:
{SSHA}xxxxxxxxxxxxxxxxxxxxxxxx
[root@dlp ~]# vi chdomain.ldif
# replace to your own domain name for "dc=***,dc=***" section
# specify the password generated above for "olcRootPW" section
 dn: olcDatabase={1}monitor,cn=config
changetype: modify
replace: olcAccess
olcAccess: {0}to * by dn.base="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth"
  read by dn.base="cn=Manager,dc=srv,dc=world" read by * none

dn: olcDatabase={2}hdb,cn=config
changetype: modify
replace: olcSuffix
olcSuffix: dc=srv,dc=world

dn: olcDatabase={2}hdb,cn=config
changetype: modify
replace: olcRootDN
olcRootDN: cn=Manager,dc=srv,dc=world

dn: olcDatabase={2}hdb,cn=config
changetype: modify
add: olcRootPW
olcRootPW: {SSHA}xxxxxxxxxxxxxxxxxxxxxxxx

dn: olcDatabase={2}hdb,cn=config
changetype: modify
add: olcAccess
olcAccess: {0}to attrs=userPassword,shadowLastChange by
  dn="cn=Manager,dc=srv,dc=world" write by anonymous auth by self write by * none
olcAccess: {1}to dn.base="" by * read
olcAccess: {2}to * by dn="cn=Manager,dc=srv,dc=world" write by * read

[root@dlp ~]# ldapmodify -Y EXTERNAL -H ldapi:/// -f chdomain.ldif 
SASL/EXTERNAL authentication started
SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth
SASL SSF: 0
modifying entry "olcDatabase={1}monitor,cn=config"

modifying entry "olcDatabase={2}hdb,cn=config"

modifying entry "olcDatabase={2}hdb,cn=config"

modifying entry "olcDatabase={2}hdb,cn=config"

[root@dlp ~]# vi basedomain.ldif
# replace to your own domain name for "dc=***,dc=***" section
 dn: dc=srv,dc=world
objectClass: top
objectClass: dcObject
objectclass: organization
o: Server World
dc: Srv

dn: cn=Manager,dc=srv,dc=world
objectClass: organizationalRole
cn: Manager
description: Directory Manager

dn: ou=People,dc=srv,dc=world
objectClass: organizationalUnit
ou: People

dn: ou=Group,dc=srv,dc=world
objectClass: organizationalUnit
ou: Group

[root@dlp ~]# ldapadd -x -D cn=Manager,dc=srv,dc=world -W -f basedomain.ldif 
Enter LDAP Password: # directory manager's password
adding new entry "dc=srv,dc=world"

adding new entry "cn=Manager,dc=srv,dc=world"

adding new entry "ou=People,dc=srv,dc=world"

adding new entry "ou=Group,dc=srv,dc=world"

開放埠

# systemctl stop firewalld
# systemctl disable firewalld
# setenforce 0

新增一個使用者

# generate encrypted password

 dn: uid=cent,ou=People,dc=srv,dc=world
objectClass: inetOrgPerson
objectClass: posixAccount
objectClass: shadowAccount
cn: Cent
sn: Linux
userPassword: {SSHA}xxxxxxxxxxxxxxxxx
loginShell: /bin/bash
uidNumber: 1000
gidNumber: 1000
homeDirectory: /home/cent

dn: cn=cent,ou=Group,dc=srv,dc=world
objectClass: posixGroup
cn: Cent
gidNumber: 1000
memberUid: cent

[root@dlp ~]# ldapadd -x -D cn=Manager,dc=srv,dc=world -W -f ldapuser.ldif 
Enter LDAP Password:
adding new entry "uid=cent,ou=People,dc=srv,dc=world"

adding new entry "cn=cent,ou=Group,dc=srv,dc=world"

新增本機的使用者和群組到ldap目錄

[root@dlp ~]# vi ldapuser.sh
# extract local users and groups who have 1000-9999 digit UID
# replace "SUFFIX=***" to your own domain name
# this is an example
 #!/bin/bash

3、安裝phpLDAPadmin來web配置LDAP

安裝和配置httpd

[root@www ~]# yum -y install httpd
# remove welcome page
[root@www ~]# rm -f /etc/httpd/conf.d/welcome.conf
[root@www ~]# vi /etc/httpd/conf/httpd.conf
# line 86: change to admin's email address
ServerAdmin root@srv.world
# line 95: change to your server's name
ServerName www.srv.world:80
# line 151: change
AllowOverride All
# line 164: add file name that it can access only with directory's name
DirectoryIndex index.html index.cgi index.php
# add follows to the end
# server's response header
ServerTokens Prod
# keepalive is ON
KeepAlive On
[root@www ~]# systemctl start httpd
[root@www ~]# systemctl enable httpd
[root@www ~]# vi /var/www/html/index.html
 <html>
<body>
<div style="width: 100%; font-size: 40px; font-weight: bold; text-align: center;">
Test Page
</div>
</body>
</html>

安裝php

[root@www ~]# yum -y install php php-mbstring php-pear
[root@www ~]# vi /etc/php.ini
# line 878: uncomment and add your timezone
date.timezone = "Asia/Shanghai"
[root@www ~]# systemctl restart httpd
[root@www ~]# vi /var/www/html/index.php
 <html>
<body>
<div style="width: 100%; font-size: 40px; font-weight: bold; text-align: center;">
<?php
   print Date("Y/m/d");
?>
</div>
</body>
</html>

安裝phpLDAP admin

[root@dlp ~]# wget http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
[root@dlp ~]# rpm -ivh epel-release-latest-7.noarch.rpm
[root@dlp ~]# yum repolist      ##檢查是否已新增至源列表
# install from EPEL
[root@dlp ~]# yum --enablerepo=epel -y install phpldapadmin
[root@dlp ~]# vi /etc/phpldapadmin/config.php
# line 397: uncomment, line 398: comment out
$servers->setValue('login','attr','dn');
// $servers->setValue('login','attr','uid');
[root@dlp ~]# vi /etc/httpd/conf.d/phpldapadmin.conf
Alias /phpldapadmin /usr/share/phpldapadmin/htdocs
Alias /ldapadmin /usr/share/phpldapadmin/htdocs
<Directory /usr/share/phpldapadmin/htdocs>
  <IfModule mod_authz_core.c>
    # Apache 2.4
    # line 12: add access permission
    Require local
    Require ip 10.0.0.0/24
[root@dlp ~]# systemctl restart httpd
