## 1. 安装OpenLDAP Server

```
[root@ldap1 ~]# yum -y install openldap-servers openldap-clients
[root@ldap1 ~]# cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG 
[root@ldap1 ~]# chown ldap. /var/lib/ldap/DB_CONFIG
[root@ldap1 ~]# systemctl start slapd 
[root@ldap1 ~]# systemctl enable slapd 
Created symlink from /etc/systemd/system/multi-user.target.wants/slapd.service to /usr/lib/systemd/system/slapd.service.
```

## 2. 配置LDAP管理密码

```
[root@ldap1 ~]# slappasswd
New password: 
Re-enter new password: 
{SSHA}4qqh8MPd8dGZdjys6+k7fap4z6nXQKvw

[root@ldap1 ~]# vi chrootpw.ldif
# specify the password generated above for "olcRootPW" section
dn: olcDatabase={0}config,cn=config
changetype: modify
add: olcRootPW
olcRootPW: {SSHA}4qqh8MPd8dGZdjys6+k7fap4z6nXQKvw

[root@ldap1 ~]# 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. 导入基础Schemas
```
[root@ldap1 ~]# 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@ldap1 ~]# 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@ldap1 ~]# 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"

```

## 4. 配置域

```
[root@ldap1 ~]# slappasswd 
New password: 
Re-enter new password: 
{SSHA}jezVaJuvRGc4KQ99LXfS7NDtk5paMy0z

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=kkops,dc=com" read by * none

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

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

dn: olcDatabase={2}hdb,cn=config
changetype: modify
add: olcRootPW
olcRootPW: {SSHA}jezVaJuvRGc4KQ99LXfS7NDtk5paMy0z

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

[root@ldap1 ~]# 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"

vi basedomain.ldif
# replace to your own domain name for "dc=***,dc=***" section
dn: dc=kkops,dc=com
objectClass: top
objectClass: dcObject
objectclass: organization
o: Server World
dc: kkops

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

dn: ou=People,dc=kkops,dc=com
objectClass: organizationalUnit
ou: People

dn: ou=Group,dc=kkops,dc=com

[root@ldap1 ~]# ldapadd -x -D cn=Manager,dc=kkops,dc=com -W -f basedomain.ldif
Enter LDAP Password: 
adding new entry "dc=kkops,dc=com"

adding new entry "cn=Manager,dc=kkops,dc=com"

adding new entry "ou=People,dc=kkops,dc=com"
