LDAP是轻量目录访问协议，英文全称是Lightweight Directory Access Protocol，一般都简称为LDAP。它是基于X.500标准的，但是简单多了并且可以根据需要定制。与X.500不同，LDAP支持TCP/IP，这对访问Internet是必须的。LDAP的核心规范在RFC中都有定义，所有与LDAP相关的RFC都可以在LDAPman RFC网页中找到。

安装openldap服务端
yum install openldap-servers openldap-clients -y
cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG
chown -R ldap.ldap /var/lib/ldap
systemctl enable slapd
systemctl start slapd
systemctl status slapd
设置ldap的管理员用户的密码
# 设置ldap的管理员密码，用户名为root,密码设置为jason_zhang
[root@VM_0_15_centos ~]# slappasswd
New password:
Re-enter new password:
{SSHA}AzIMaeCb+UqudqCA6OIU2J/w79oVOG/Q ##记住该密码 # 创建ldif文件
[root@VM_0_15_centos ldap]# cd /etc/openldap/
[root@VM_0_15_centos openldap]# mkdir myself
[root@VM_0_15_centos openldap]# cd myself/
[root@VM_0_15_centos myself]# vim chrootpw.ldif
dn: olcDatabase={}config,cn=config
changetype: modify
add: olcRootPW
olcRootPW: {SSHA}AzIMaeCb+UqudqCA6OIU2J/w79oVOG/Q # 根据文件导入
[root@VM_0_15_centos myself]# ldapadd -Y EXTERNAL -H ldapi:/// -f chrootpw.ldif
SASL/EXTERNAL authentication started
SASL username: gidNumber=+uidNumber=,cn=peercred,cn=external,cn=auth
SASL SSF:
modifying entry "olcDatabase={0}config,cn=config"
添加基础的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
设置根域和数据库超级管理员
为了方便，我们还是使用上面的管理员密码来设置数据库库的密码。
创建
domain-dbadmin.ldif文件
[root@archery myself]# pwd
/etc/openldap/myself
vim domain-dbadmin.ldif
[root@archery myself]# cat domain-dbadmin.ldif
