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}#rootpw\t{SSHA}#g"
rootpw {SSHA}D9+lqUJZVPobp0sZfXl37jE1aVvR2P9K
[root@node5 openldap]# slappasswd -s chinasoft|sed -e "s#{SSHA}#rootpw\t{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"
对比修改是否成功:
# diff slapd.conf.bak slapd.conf
114,117c114,122
< database bdb
< suffix "dc=my-domain,dc=com"
< checkpoint 1024 15
< rootdn "cn=Manager,dc=my-domain,dc=com"
---
> #database bdb
> #suffix "dc=my-domain,dc=com"
> #checkpoint 1024 15
> #rootdn "cn=Manager,dc=my-domain,dc=com"
> # add start by jack 2016/07/01
> database dbd
> suffix "dc=chinasoft,dc=com"
> rootdn "cn=admin,dc=chinasoft,dc=com"
>
140a146
> rootpw {SSHA}FvBRnIPqtIi0/u11O2gOfOCrRJr+xMAr
添加如下内容
cat >> /etc/openldap/slapd.conf<
loglevel 296
cachesize 1000
checkpoint 2018 10
EOF
参数说明:
# add start by jack 2016/07/01
loglevel 296 # 日志级别,记录日志信息方便调试,296级别是由256(日志连接/操作/结果)、32(搜索过滤器处理)、8(连接管理)累加的结果
cachesize 1000 # 设置ldap可以换成的记录数
checkpoint 2018 10 # 可以设置把内存中的数据协会数据文件的操作上,上面设置表示每达到2048KB或者10分钟执行一次,checkpoint即写入数据文件的操作
4.ldap授权及安全参数配置
# vim /etc/openldap/slapd.conf删除如下内容:
database config
access to *
by dn.exact="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth" manage
by * none
# enable server status monitoring (cn=monitor)
database monitor
access to *
by dn.exact="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth" read
by dn.exact="cn=Manager,dc=my-domain,dc=com" read
by * none
改为:
access to *
by self write
by anonymous auth
by * read
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 ? 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:off 1:off 2:on 3:on 4:on 5:on 6: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:
报错:
ldap_bind: Invalid credentials (49)
解决办法:
# rm -rf /etc/openldap/slapd.d/*
# slaptest -f /etc/openldap/slapd.conf -F /etc/openldap/slapd.d
57763ec6 bdb_monitor_db_open: monitoring disabled; configure monitor database to enable
config file testing succeeded
# ldapsearch -LLL -W -x -H ldap://chinasoft.com -D "cn=admin,dc=chinasoft,dc=com" -b "dc=chinasoft,dc=com" "(uid=*)"
Enter LDAP Password:
No such object (32)
重启服务
# service slapd restart

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
编辑一个LDIF格式文件:# vim base.ldif
dn: dc=chinasoft, dc=com
objectClass: organization
objectClass: dcObject
dc: chinasoft
o: chinasoft
dn: ou=People, dc=chinasoft, dc=com
objectClass: organizationalUnit
ou: People
dn: ou=group, dc=chinasoft, dc=com
objectClass: organizationalUnit
ou: group
dn: cn=tech, ou=group, dc=chinasoft, dc=com
objectClass: posixGroup
description:: 5oqA5pyv6YOo
gidNumber: 10001
cn: tech
# vim jack.ldif
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
# ldapadd -x -H ldap://chinasoft.com -D "cn=admin,dc=chinasoft,dc=com" -W -f base.ldif
Enter LDAP Password:
adding new entry "dc=chinasoft, dc=com"
adding new entry "ou=People, dc=chinasoft, dc=com"
adding new entry "ou=group, dc=chinasoft, dc=com"
adding new entry "cn=tech, ou=group, dc=chinasoft, dc=com"
2) 运行ldapadd
# ldapadd -x -H ldap://chinasoft.com -D "cn=admin,dc=chinasoft,dc=com" -W -f base.ldifEnter LDAP Password:
报错:
adding new entry "dc=chinasoft,dc=com"
ldap_add: Invalid syntax (21)
additional info: objectClass: value #0 invalid per syntax
原因:ldif文件中存在空格 或者 个别单词拼写错误
正确书写格式:
(1空行)
dn:(空格) dc=mail,dc=kaspersky,dc=com(结尾无空格)
objectclass: (空格)dcObject(结尾无空格)
objectclass: (空格)organization(结尾无空格)
o: (空格)kaspersky(结尾无空格)
dc:(空格) test(结尾无空格)
(1空行)
dn: (空格)cn=test,dc=mail,dc=kaspersky,dc=com(结尾无空格)
objectclass: (空格)organizationalRole(结尾无空格)
cn: (空格)test(结尾无空格)
(结尾无空行)
# 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/releases?page=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
[root@node5 config]# diff lam.conf_sample 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
添加用户、配置密码
查看通过web界面添加的tom用户是否生效# ldapsearch -LLL -W -x -H ldap://chinasoft.com -D "cn=admin,dc=chinasoft,dc=com" -b "dc=chinasoft,dc=com" "(uid=lily)"
Enter LDAP Password:
dn: uid=lily,ou=People,dc=chinasoft,dc=com
objectClass: posixAccount
objectClass: inetOrgPerson
objectClass: organizationalPerson
objectClass: person
homeDirectory: /home/lily
loginShell: /bin/bash
