CentOS7 下 OpenLDAP Server 及phpLDAPadmin安装、配置及使用

一、准备工作

1、centos 7.6最小化安装

2、将centos base源改变为国内源，选择USTC源

替换/etc/yum.repos.d/CentOS-Base.repo

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#
#

[base]
name=CentOS-$releasever - Base
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
baseurl=https://mirrors.ustc.edu.cn/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#released updates
[updates]
name=CentOS-$releasever - Updates
# mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates
baseurl=https://mirrors.ustc.edu.cn/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
# mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras
baseurl=https://mirrors.ustc.edu.cn/centos/$releasever/extras/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus
# mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus
baseurl=https://mirrors.ustc.edu.cn/centos/$releasever/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

3、添加epel源，依然选择ustc

[root@Centos7u6 ~]#yum install http://mirrors.ustc.edu.cn/epel/epel-release-latest-7.noarch.rpm

[root@Centos7u6 ~]#yum install -y epel-release
[root@Centos7u6 ~]#sed -e 's/^mirrorlist=/#mirrorlist=/g' \
         -e 's/^#baseurl=/baseurl=/g' \
         -e 's/\/download\.fedoraproject\.org\/pub/\/mirrors.ustc.edu.cn/g' \
         -e 's/http:\/\/mirrors\.ustc/https:\/\/mirrors.ustc/g' \
         -i /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel-testing.repo

4、[root@Centos7u6 ~]#yum makecache

 二、安装openLDAP

1、yum 安装openldap

[root@Centos7u6 ~]# yum install -y openldap openldap-clients openldap-servers migrationtools

[root@Centos7u6 ~]#cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG

[root@Centos7u6 ~]#chown ldap. /var/lib/ldap/DB_CONFIG

[root@Centos7u6 ~]#systemctl start slapd

[root@Centos7u6 ~]#systemctl enable slapd

2、设置openLDAP管理员密码

2.1生成加密密码

[root@Centos7u6 ~]# slappasswd
New password:
Re-enter new password:
{SSHA}JoT0Ti77zCnF3L5JdLrksg5SCVdR/HIk

2.2编辑chrootpw.ldif

"dn: olcDatabase={0}config,cn=config"
"changetype: modify"
"add: olcRootPW"
"olcRootPW: {SSHA}JoT0Ti77zCnF3L5JdLrksg5SCVdR/HIk

2.3导入chrootpw.ldif

[root@Centos7u6 ~]# 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"

3、导入基本schema

[root@Centos7u6 ~]# cd /etc/openldap/schema/

ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f cosine.ldif
ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f nis.ldif
ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f collective.ldif
ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f corba.ldif
ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f core.ldif
ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f duaconf.ldif
ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f dyngroup.ldif
ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f inetorgperson.ldif
ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f java.ldif
ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f misc.ldif
ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f openldap.ldif
ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f pmi.ldif
ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f ppolicy.ldif

 4、设置domain name

[root@Centos7u6 ~]# vim 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=xxxx,dc=edu,dc=cn" read by * none

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

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

dn: olcDatabase={2}hdb,cn=config
changetype: modify
add: olcRootPW
olcRootPW: {SSHA}JoT0Ti77zCnF3L5JdLrksg5SCVdR/HIk

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

[root@Centos7u6 ~]# 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"

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

设置basedomain

[root@Centos7u6 ~]# vim basedomain.ldif

# replace to your own domain name for "dc=***,dc=***" section

dn: dc=xxxx,dc=edu,dc=cn
objectClass: top
objectClass: dcObject
objectclass: organization
o: Server World
dc: xxxx

dn: cn=Manager,dc=xxxx,dc=edu,dc=cn

ou: Group

 

 

[root@Centos7u6 ~]# ldapadd -x -D cn=Manager,dc=xxxx,dc=edu,dc=cn -W -f basedomain.ldif
Enter LDAP Password:
adding new entry "dc=cctc,dc=edu,dc=cn"

adding new entry "cn=Manager,dc=cctc,dc=edu,dc=cn"

adding new entry "ou=People,dc=cctc,dc=edu,dc=cn"

adding new entry "ou=Group,dc=cctc,dc=edu,dc=cn"

5、设置防火墙，允许外部访问LDAP服务

[root@Centos7u6 ~]# firewall-cmd --add-service=ldap --permanent
success
[root@Centos7u6 ~]# firewall-cmd --reload
succes

6、修改SELINUX设置

[root@Centos7u6 ~]# setenforce 0
[root@Centos7u6 ~]# vim /etc/selinux/config

SELINUX=disabled 

7、添加测试用户

[root@Centos7u6 ~]# vim ldapuser.ldif

 

# create new ldap user test
# replace to your own domain name for "dc=***,dc=***" section
 
dn: uid=test,ou=People,dc=xxxx,dc=edu,dc=cn
