單台機器簡單安裝配置openldap伺服器

LDAP是輕量目錄通路協定，英文全稱是Lightweight Directory Access Protocol，一般都簡稱為LDAP。

現在市場上有關LDAP的産品已有很多，各大軟體公司都在他們的産品中內建了LDAP服務，如Microsoft的ActiveDirectory、Lotus的Domino Directory、IBM的WebSphere中也內建了LDAP服務。LDAP的開源實作是OpenLDAP，它比商業産品一點也不差，而且源碼開放。

OpenLDAP 是最常用的目錄服務之一，它是一個由開源社群及志願者開發和管理的一個開源項目，提供了目錄服務的所有功能，包括目錄搜尋、身份認證、安全通道、過濾器等等。大多數的 Linux 發行版裡面都帶有 OpenLDAP 的安裝包。

安裝openldap服務

yum install -y openldap openldap-*
cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG
systemctl restart slapd
systemctl enable slapd
           

配置ldap服務

#生成管理者密碼

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

導入基本模式

[[email protected] ~]# 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"
[[email protected] ~]# 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"
[[email protected] ~]# 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"
