安装LDAP

前提条件

  • 关闭防火墙
  • 关闭selinux

安装ldap

yum install openldap openldap-clients openldap-servers

设置管理员密码

slappasswd

设置ldap数据库

cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG
chown ldap:ldap /var/lib/ldap/*

启动ldap服务，并设置为开机启动

systemctl start slapd
systemctl enable slapd

配置ldap server

切换到ldap目录 cd /etc/openldap/slapd.d/cn=config

更新hdb.ldif * 更新my-domain为自定义的名称 * 添加olcRootPW,它的内容是上面创建的管理员密码

例如，这里更新为periky

cat <<EOF | ldapadd -Y EXTERNAL -H ldapi:///
dn: olcDatabase={2}hdb,cn=config
changetype: modify
delete: olcSuffix

dn: olcDatabase={2}hdb,cn=config
changetype: modify
add: olcSuffix
olcSuffix: dc=periky,dc=com

dn: olcDatabase={2}hdb,cn=config
changetype: modify
delete: olcRootDN

dn: olcDatabase={2}hdb,cn=config
changetype: modify
add: olcRootDN
olcRootDN: cn=Admin,dc=periky,dc=com

dn: olcDatabase={2}hdb,cn=config
changetype: modify
add: olcRootPW
olcRootPW: {SSHA}V1MUM1xql6pN3t3fMiSb4tYk5L6cZFXn
EOF

更新monitor.ldif

cat <<EOF | ldapadd -Y EXTERNAL -H ldapi:///
dn: olcDatabase={1}monitor,cn=config
changetype: modify
delete: olcAccess

dn: olcDatabase={1}monitor,cn=config
changetype: modify
add: olcAccess
olcAccess: {0}to * by dn.base="gidNumber=0+uidNumber=0,cn=peercred,cn=extern al,cn=auth" read by dn.base="cn=Admin,dc=periky,dc=com" read by * none
EOF

配置信息测试

slaptest -u
  • 输出内容 config file testing succeeded

添加ldap 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

创建ldap目录

文件名base.ldif,文件路径/root/ldap

dn: dc=periky,dc=com
dc: periky
objectClass: top
objectClass: domain

dn: cn=Admin,dc=periky,dc=com
objectClass: organizationalRole
cn: Admin
description: LDAP Manager

dn: ou=Account,dc=periky,dc=com
objectClass: organizationalUnit
ou: Account
  • 执行命令ldapadd -x -W -D "cn=Admin,dc=periky,dc=com" -f /root/ldap/base.ldif

添加用户

文件名test.ldif,文件路径/root/ldap

dn: cn=test,ou=Account,dc=periky,dc=com
cn: test
gidnumber: 10000
homedirectory: /home/dev
loginshell: /bin/bash
objectclass: posixAccount
objectclass: inetOrgPerson
objectclass: organizationalPerson
objectclass: person
sn: test
uid: test
uidnumber: 10001
  • ldapadd -x -W -D "cn=Admin,dc=periky,dc=com" -f /root/ldap/test.ldif
