怎样用centos7搭建openstack

安装ldap服务

[root@ldap ~]# yum install -y openldap-servers openldap-clients

[root@ldap ~]# cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG

[root@ldap ~]# chown ldap. /var/lib/ldap/DB_CONFIG

[root@ldap ~]# systemctl start slapd

[root@ldap ~]# systemctl enable slapd

配置ldap服务

# 生成管理员密码

[root@ldap ~]# slappasswd

New password:

Re-enter new password:

{SSHA}xxxxxxxxxxxxxxxxxxxxxxxx

[root@ldap ~]# vim chrootpw.ldif

# specify the password generated above for "olcRootPW" section

dn: olcDatabase={0}config,cn=config

changetype: modify

add: olcRootPW

olcRootPW: {SSHA}xxxxxxxxxxxxxxxxxxxxxxxx

[root@ldap ~]# 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"

导入基本模式

[root@ldap ~]# 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@ldap ~]# 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@ldap ~]# ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/openldap/schema/inetorgperson.ldif

SASL/EXTERNAL authentication started
