配置OpenLDAP数据库

cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG
chown ldap:ldap -R /var/lib/ldap
chmod 700 -R /var/lib/ldap
ll /var/lib/ldap/

注意：/var/lib/ldap/就是BerkeleyDB数据库默认存储的路径。

导入基本Schema

ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/openldap/schema/cosine.ldif
ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/openldap/schema/nis.ldif
ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/openldap/schema/inetorgperson.ldif

输出

[root@kudu ~]# 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@kudu ~]# 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@kudu ~]# 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"

修改migrate_common.ph文件

vi /usr/share/migrationtools/migrate_common.ph
修改如下变量

$DEFAULT_MAIL_DOMAIN = "haohaozhu.com";
$DEFAULT_BASE = "dc=haohaozhu,dc=com";
$EXTENDED_SCHEMA = 1;

添加用户及用户组

默认情况下OpenLDAP是没有普通用户的，但是有一个管理员用户。管理用户就是前面我们刚刚配置的root。
现在我们把系统中的用户，添加到OpenLDAP中。为了进行区分，我们现在新加两个用户ldapuser1和ldapuser2，和两个用户组ldapgroup1和ldapgroup2，如下：
添加用户组，使用如下命令：

groupadd ldapgroup1
groupadd ldapgroup2

添加用户并设置密码，使用如下命令

useradd -g ldapgroup1 ldapuser1
useradd -g ldapgroup2 ldapuser2
passwd  ldapuser1
passwd  ldapuser2

密码都设置为：hadoop

提取用户和组

grep ":10[0-9][0-9]" /etc/passwd > /root/users
grep ":10[0-9][0-9]" /etc/group > /root/groups

结果

[root@kudu ~]# cat users
ldapuser1:x:1000:1000::/home/ldapuser1:/bin/bash
ldapuser2:x:1001:1001::/home/ldapuser2:/bin/bash
[root@kudu ~]# cat groups
ldapgroup1:x:1000:
ldapgroup2:x:1001:

生成用户和组的ldif文件

/usr/share/migrationtools/migrate_passwd.pl /root/users > /root/users.ldif
/usr/share/migrationtools/migrate_group.pl /root/groups > /root/groups.ldif
cat /root/users.ldif
cat /root/groups.ldif

输出

[root@kudu ~]# cat /root/groups.ldif
dn: cn=ldapgroup1,ou=Group,dc=haohaozhu,dc=com
objectClass: posixGroup
objectClass: top
cn: ldapgroup1
userPassword: {crypt}x
gidNumber: 1000

dn: cn=ldapgroup2,ou=Group,dc=haohaozhu,dc=com
objectClass: posixGroup
objectClass: top
cn: ldapgroup2
userPassword: {crypt}x
gidNumber: 1001

导入用户及用户组到OpenLDAP数据库

配置openldap基础的数据库，如下：

cat > /root/base.ldif << EOF
dn: dc=haohaozhu,dc=com
o: haohaozhu com
dc: haohaozhu
objectClass: top
objectClass: dcObject
objectclass: organization

dn: cn=Manager,dc=haohaozhu,dc=com
cn: Manager
objectClass: organizationalRole
description: Directory Manager

dn: ou=People,dc=haohaozhu,dc=com
ou: People
objectClass: top
objectClass: organizationalUnit

dn: ou=Group,dc=haohaozhu,dc=com
ou: Group
objectClass: top
objectClass: organizationalUnit
EOF

导入基础数据库，使用如下命令：

ldapadd -x -w "hadoop" -D "cn=Manager,dc=haohaozhu,dc=com" -f /root/base.ldif

输出

[root@kudu ~]# ldapadd -x -w "hadoop" -D "cn=Manager,dc=haohaozhu,dc=com" -f /root/base.ldif
adding new entry "dc=haohaozhu,dc=com"
adding new entry "cn=Manager,dc=haohaozhu,dc=com"
adding new entry "ou=People,dc=haohaozhu,dc=com"
adding new entry "ou=Group,dc=haohaozhu,dc=com"

导入用户

ldapadd -x -w "hadoop" -D "cn=Manager,dc=haohaozhu,dc=com" -f /root/users.ldif

输出

[root@kudu ~]# ldapadd -x -w "hadoop" -D "cn=Manager,dc=haohaozhu,dc=com" -f /root/users.ldif
adding new entry "uid=ldapuser1,ou=People,dc=haohaozhu,dc=com"
adding new entry "uid=ldapuser2,ou=People,dc=haohaozhu,dc=com"

导入用户组

ldapadd -x -w "hadoop" -D "cn=Manager,dc=haohaozhu,dc=com" -f /root/groups.ldif

输出

[root@kudu ~]# ldapadd -x -w "hadoop" -D "cn=Manager,dc=haohaozhu,dc=com" -f /root/groups.ldif
adding new entry "cn=ldapgroup1,ou=Group,dc=haohaozhu,dc=com"
adding new entry "cn=ldapgroup2,ou=Group,dc=haohaozhu,dc=com"

把OpenLDAP用户加入到用户组

尽管我们已经把用户和用户组信息，导入到OpenLDAP数据库中了。但实际上目前OpenLDAP用户和用户组之间是没有任何关联的。
如果我们要把OpenLDAP数据库中的用户和用户组关联起来的话，我们还需要做另外单独的配置。
现在我们要把ldapuser1用户加入到ldapgroup1用户组，需要新建添加用户到用户组的ldif文件，如下

cat > add_user_to_groups.ldif << "EOF"
dn: cn=ldapgroup1,ou=Group,dc=haohaozhu,dc=com
changetype: modify
add: memberuid
memberuid: ldapuser1
EOF

导入ldif

ldapadd -x -w "hadoop" -D "cn=Manager,dc=haohaozhu,dc=com" -f /root/add_user_to_groups.ldif

输出

[root@kudu ~]# ldapadd -x -w "hadoop" -D "cn=Manager,dc=haohaozhu,dc=com" -f /root/add_user_to_groups.ldif
modifying entry "cn=ldapgroup1,ou=Group,dc=haohaozhu,dc=com"

查询用户

ldapsearch -LLL -x -D 'cn=Manager,dc=haohaozhu,dc=com' -w "hadoop" -b 'dc=haohaozhu,dc=com' 'cn=ldapgroup1'

输出

[root@kudu ~]# ldapsearch -LLL -x -D 'cn=Manager,dc=haohaozhu,dc=com' -w "hadoop" -b 'dc=haohaozhu,dc=com' 'cn=ldapgroup1'
dn: cn=ldapgroup1,ou=Group,dc=haohaozhu,dc=com
objectClass: posixGroup
objectClass: top
cn: ldapgroup1
userPassword:: e2NyeXB0fXg=
gidNumber: 1000
memberUid: ldapuser1

开启OpenLDAP日志访问功能

默认情况下OpenLDAP是没有启用日志记录功能的，但是在实际使用过程中，我们为了定位问题需要使用到OpenLDAP日志。
新建日志配置ldif文件，如下

cat > /root/loglevel.ldif << "EOF"
dn: cn=config
changetype: modify
replace: olcLogLevel
olcLogLevel: stats
EOF

导入到OpenLDAP中，并重启OpenLDAP服务，如下：

ldapmodify -Y EXTERNAL -H ldapi:/// -f /root/loglevel.ldif
systemctl restart slapd

修改rsyslog配置文件，并重启rsyslog服务，如下：

cat >> /etc/rsyslog.conf << "EOF"
local4.* /var/log/slapd.log
EOF
systemctl restart rsyslog

安装和配置LDAP管理工具PHPldapadmin

[root@localhost ~]# yum -y install httpd php php-ldap php-gd php-mbstring php-pear php-bcmath php-xml
[root@localhost ~]# yum -y install epel-release
[root@localhost ~]# yum --enablerepo=epel -y install phpldapadmin

修改配置文件

[root@localhost ~]# vim /etc/phpldapadmin/config.php
#397行取消注释，398行添加注释
$servers->setValue('login','attr','dn');
// $servers->setValue('login','attr','uid');

[root@localhost ~]# vim /etc/httpd/conf.d/phpldapadmin.conf

// 修改配置
<IfModule mod_authz_core.c>
# Apache 2.4
Require local
#添加一行内容，指定可访问的ip段
Require ip 172.16.186.58
</IfModule>

设置开机自启并启动Apache：

systemctl enable httpd
systemctl start httpd

登陆web控制台

http://172.16.27.7/phpldapadmin/

用户名：cn=Manager,dc=haohaozhu,dc=com
密码：hadoop
