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

ldap环境安装
1-1检查系统环境

配置yum源，保留rpm原有的包
[root@vm0021 xuqizhang]# sed -i's#keepcache=0#keepcache=1#g' /etc/yum.conf
[root@vm0021 xuqizhang]# grep keepcache/etc/yum.conf
keepcache=1
关闭selinux防火墙以及防火墙

设定ldap域名并配置host

开始安装ldap master
openldap依赖的软件很多，我们一般功能性软件都用yum安装，定制的软件用源码安装
安装前：检查
[root@vm0021 xuqizhang]# rpm -qa openldap
openldap-2.4.40-12.el6.x86_64
[root@vm0021 xuqizhang]# rpm -qa |grepopenldap
openldap-2.4.40-12.el6.x86_64
openldap-devel-2.4.40-12.el6.x86_64
安装
[root@vm0021 xuqizhang]# yum -y installopenldap openldap-* -y
[root@vm0021 xuqizhang]# yum -y installnscd nss-pam-ldap nss-* pcre pcre-*
安装好检查一下，出现以下包就ok
[root@vm0021 xuqizhang]# rpm -qa |grepopenldap
openldap-clients-2.4.40-12.el6.x86_64
openldap-servers-2.4.40-12.el6.x86_64
openldap-servers-sql-2.4.40-12.el6.x86_64
openldap-2.4.40-12.el6.x86_64
openldap-devel-2.4.40-12.el6.x86_64
小提示：如果以上安装出现报错，建议依赖包分开yum安装
配置ldap master
