CentOS6.5安装openLdap

2022-07-28 20:54:00

一、关闭防火墙和selinux

关闭防火墙

chkconfig iptables off

service iptables stop

关闭selinux

vim /etc/selinux/config将配置修改为

SELINUX=disabled

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<<EOF
# add start by jack 2016/07/01
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

#如果需要更改新的配置情况，删除原配置，生成新配置，比如，需要修改超级管理员的密码情况，
#如果不是，可以跳过这个步骤

cd /etc/ldap/

rm -rf slapd.d/*

slaptest -f slapd.conf -F slapd.d/

cd slapd.d/      
可能会有报错，不过不影响，有文件就算是成功的

7.启动服务：

# /etc/init.d/slapd restart

# lsof -i :

COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME

slapd    ldap    7u  IPv4        0t0  TCP *:ldap (LISTEN)

slapd    ldap    8u  IPv6        0t0  TCP *:ldap (LISTEN)

[root@node5 openldap]# ps -ef |grep ldap|grep -v grep

ldap             : ?        :: /usr/sbin/slapd -h  ldap:/// ldapi:/// -u ldap

配置随机启动

# chkconfig slapd on

[root@node5 openldap]# chkconfig --list slapd

slapd           :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:

报错：

ldap_bind: Invalid credentials ()

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:

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:   

gidNumber:   

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.ldif
Enter LDAP Password: 
adding new entry "dc=chinasoft,dc=com"

ldap_add: Invalid syntax ()  

additional info: objectClass: value # 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:

gidNumber:

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.-.el6.x86_64

httpd-2.2.-.el6.centos.x86_64

php-gd-5.3.-.el6.x86_64

php-ldap-5.3.-.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

13c13  

< admins: cn=Manager,dc=my-domain,dc=com

< types: suffix_smbDomain: dc=my-domain,dc=com  

---  

> types: suffix_smbDomain: dc=chinasoft,dc=com  

# 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
