ldap常用名称解释

1.环境搭建

操作系统：centos6.5 x86_64
关闭防火墙、selinux
开启时间同步
# crontab -e
加入
# time sync
*/5 * * * * /usr/sbin/ntpdate 192.168.8.102 >/dev/null 2>&1
# crontab -l
*/5 * * * * /usr/sbin/ntpdate -u 192.168.8.102 >/dev/null 2>&1

配置域名解析：
# echo “192.168.8.43 chinasoft.com” >> /etc/hosts

解决依赖关系
# yum grouplist

   Base
   Debugging Tools
   Performance Tools
   Compatibility libraries
   Development tools
   Dial-up Networking Support
   Hardware monitoring utilities
如果缺少组包，需要安装
yum groupinstall -y “Compatibility libraries”

2.安装openldap master

# yum install -y openldap openldap-*
# yum install -y nscd nss-pam-ldapd nss-* pcre pcre*

# rpm -qa | grep openldap*
compat-openldap-2.3.43-2.el6.x86_64
openldap-2.4.40-12.el6.x86_64
openldap-clients-2.4.40-12.el6.x86_64
openldap-servers-sql-2.4.40-12.el6.x86_64
openldap-servers-2.4.40-12.el6.x86_64
openldap-devel-2.4.40-12.el6.x86_64

3.配置slapd.conf文件

# cd /etc/openldap/
[root@node5 openldap]# cp /usr/share/openldap-servers/slapd.conf.obsolete slapd.conf

[root@node5 openldap]# cp slapd.conf slapd.conf.bak
[root@node5 openldap]# slappasswd -s chinasoft|sed -e “s#{SSHA}#rootpwt{SSHA}#g”
rootpw {SSHA}D9+lqUJZVPobp0sZfXl37jE1aVvR2P9K
[root@node5 openldap]# slappasswd -s chinasoft|sed -e “s#{SSHA}#rootpwt{SSHA}#g”>>/etc/openldap/slapd.conf
[root@node5 openldap]# tail -1 slapd.conf
rootpw {SSHA}FvBRnIPqtIi0/u11O2gOfOCrRJr+xMAr

# vim slapd.conf
注释掉一下四行
# database        dbb
#suffix         “dc=my-domain,dc=com”
#checkpoint     1024 15
#rootdn         “cn=Manager,dc=my-domain,dc=com”

添加如下内容
# add start by jack 2016/07/01
database        bdb
suffix          “dc=chinasoft,dc=com”
rootdn          “cn=admin,dc=chinasoft,dc=com”

5.加入日志记录

# cp /etc/rsyslog.conf /etc/rsyslog.conf.bak.$(date +%F%T)
# echo ‘#record ldap.log by jack 2016-07-01’ >> /etc/rsyslog.conf
# echo ‘local4.* /var/log/ldap.log’>> /etc/rsyslog.conf
# tail -1 /etc/rsyslog.conf
local4.* /var/log/ldap.log
# service rsyslog restart

6.配置ldap数据库路径

# cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG
[root@node5 openldap]# ll /var/lib/ldap/DB_CONFIG 
-rw-r–r– 1 root root 845 Jul  1 17:29 /var/lib/ldap/DB_CONFIG
[root@node5 openldap]# chown ldap:ldap /var/lib/ldap/DB_CONFIG 
[root@node5 openldap]# chmod 700 /var/lib/ldap/
[root@node5 openldap]# ls -l /var/lib/ldap/
total 4
-rw-r–r– 1 ldap ldap 845 Jul  1 17:29 DB_CONFIG

验证配置是否Ok
# slaptest -u
config file testing succeeded

7.启动服务：

# /etc/init.d/slapd restart
# lsof -i :389
COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
slapd   50735 ldap    7u  IPv4  75541      0t0  TCP *:ldap (LISTEN)
slapd   50735 ldap    8u  IPv6  75542      0t0  TCP *:ldap (LISTEN)
[root@node5 openldap]# ps -ef |grep ldap|grep -v grep
ldap     50735     1  0 17:33 nbsp;      00:00:00 /usr/sbin/slapd -h  ldap:/// ldapi:/// -u ldap
配置随机启动
# chkconfig slapd on
[root@node5 openldap]# chkconfig –list slapd
slapd           0:off1:off2:on3:on4:on5:on6:off

8.测试查找内容

# ldapsearch -LLL -W -x -H ldap://chinasoft.com -D “cn=admin,dc=chinasoft,dc=com” -b “dc=chinasoft,dc=com” “(uid=*)”
Enter LDAP Password: 
错：
ldap_bind: Invalid credentials (49)

解决办法：

重启服务
# service slapd restart
Stopping slapd:                                            [FAILED]
Checking configuration files for slapd:                    [FAILED]
57763eee ldif_read_file: Permission denied for “/etc/openldap/slapd.d/cn=config.ldif”
slaptest: bad configuration file!
[root@node5 openldap]# chown -R ldap.ldap /etc/openldap/slapd.d/
[root@node5 openldap]# service slapd restart
Stopping slapd:                                            [FAILED]
Starting slapd:                                            [  OK  ]

# lsof -i :389
COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
slapd   51164 ldap    7u  IPv4  77503      0t0  TCP *:ldap (LISTEN)
slapd   51164 ldap    8u  IPv6  77504      0t0  TCP *:ldap (LISTEN)

9.为ldap master初始化数据(如果不初始化，后面无法通过web界面管理)

增加初始的入口(entries) 

1) 创建LDIF文件 

# vim jack.ldif

2) 运行ldapadd

# ldapadd -x -H ldap://chinasoft.com -D “cn=admin,dc=chinasoft,dc=com” -W -f base.ldif
Enter LDAP Password: 

# ldapadd -x -H ldap://chinasoft.com -D “cn=admin,dc=chinasoft,dc=com” -W -f jack.ldif 
Enter LDAP Password: 
adding new entry “uid=jack,ou=People,dc=chinasoft,dc=com”

3) 检查是否已经开始正常工作 

# ldapsearch -LLL -W -x -H ldap://chinasoft.com -D “cn=admin,dc=chinasoft,dc=com” -b “dc=chinasoft,dc=com” “(uid=*)”
Enter LDAP Password: 
dn: uid=jack,ou=People,dc=chinasoft,dc=com
objectClass: posixAccount
objectClass: inetOrgPerson
objectClass: organizationalPerson
objectClass: person
homeDirectory: /home/jack
loginShell: /bin/bash
uid: jack
cn: jack
userPassword:: 55G/ReqPKeOZ8SpgszwIQhaBXySNU4mw
uidNumber: 10005
gidNumber: 10001
sn: jack

10.为ldap master配置web管理接口

安装lamp环境
# yum install -y httpd php php-ldap php-gd

# rpm -qa httpd php php-ldap php-gd
php-5.3.3-47.el6.x86_64
httpd-2.2.15-53.el6.centos.x86_64
php-gd-5.3.3-47.el6.x86_64
php-ldap-5.3.3-47.el6.x86_64

安装ldap-account-manager管理软件
https://www.ldap-account-manager.org/lamcms/releasesge=3
将ldap-account-manager-3.7.tar.gz安装包上传到/var/www/html目录
# cd /var/www/html/
[root@node5 html]# tar zxf ldap-account-manager-3.7.tar.gz 
[root@node5 html]# mv ldap-account-manager-3.7 ldap
[root@node5 html]# cd ldap/config
[root@node5 config]# cp config.cfg_sample config.cfg
[root@node5 config]# cp lam.conf_sample lam.conf
[root@node5 config]# sed -i ‘s#cn=Manager#cn=admin#g’ lam.conf
[root@node5 config]# sed -i ‘s#dc=my-domain#dc=chinasoft#g’ lam.conf

# chown -R apache.apache /var/www/html/ldap

访问http://192.168.8.43/ldap/templates/login.php
使用刚才配置的 admin 和密码chinasoft登陆即可

查看通过web界面添加的tom用户是否生效
