192.168.199.118 | yfm18 | ldap server |
192.168.199.117 | yfm17 | ldap client |
在yfm18上执行
安装 OpenLDAP 服务端,设置数据库配置文件
yum -y install openldap-servers openldap-clients
cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG
chown ldap.ldap /var/lib/ldap/DB_CONFIG
启动
systemctl start slapd
开机自启
systemctl enable slapd
设置 OpenLDAP 的管理员用户 root 的密码123456
[root@yfm18 ldap]# slappasswd
New password:
Re-enter new password:
{SSHA}C1vMXU5d5YaC2/tJKVlczBNZA9pWTBCw
将生成的密码添加至 OpenLDAP 的 ldif 文件中。LDIF 是修改 OpenLDAP 内容的标准文本格式
vi chrootpw.ldif
dn: olcDatabase={0}config,cn=config
changetype: modify
add: olcRootPW
olcRootPW: {SSHA}C1vMXU5d5YaC2/tJKVlczBNZA9pWTBCw
[root@yfm18 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"
添加几个基础的 Schema,此处添加的 Schema 主要用于记录人员信息。如果搭建该 OpenLDAP 的目的为用户认证,一般都会导入以下 Schema
ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/openldap/schema/cosine.ldif
ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/openldap/schema/nis.ldif
ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/openldap/schema/inetorgperson.ldif
在 LDAP 数据库中设置根域和数据库超级管理员
这里的“根域”可以和这台服务器 FQDN 中的根域不同,此处我们设置为 dc=colinlee,dc=fish。
数据库管理员和上面设置过的 OpenLDAP 超级管理员并非同一管理员,而且这里设置的管理员目前尚未创建。此处的设置同样需要一个用 slappasswd 命令生成的密码,为了方便管理,我们使用刚刚生成的密码,不再重新生成
vi chdomain.ldif
dn: olcDatabase={1}monitor,cn=config
changetype: modify
replace: olcAccess
olcAccess: {0}to *
by dn.base="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth" read
by dn.base="cn=admin,dc=colinlee,dc=fish" read
by * none
dn: olcDatabase={2}hdb,cn=config
changetype: modify
replace: olcSuffix
olcSuffix: dc=colinlee,dc=fish
dn: olcDatabase={2}hdb,cn=config
changetype: modify
replace: olcRootDN
olcRootDN: cn=admin,dc=colinlee,dc=fish
dn: olcDatabase={2}hdb,cn=config
changetype: modify
add: olcRootPW
olcRootPW: {SSHA}C1vMXU5d5YaC2/tJKVlczBNZA9pWTBCw
dn: olcDatabase={2}hdb,cn=config
changetype: modify
add: olcAccess
olcAccess: {0}to attrs=userPassword,shadowLastChange
by dn="cn=admin,dc=colinlee,dc=fish" write
by anonymous auth
by self write
by * none
olcAccess: {1}to dn.base=""
by * read
olcAccess: {2}to *
by dn="cn=admin,dc=colinlee,dc=fish" write
by * read
[root@yfm18 ldap]# ldapmodify -Y EXTERNAL -H ldapi:/// -f chdomain.ldif
SASL/EXTERNAL authentication started
SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth
SASL SSF: 0
modifying entry "olcDatabase={1}monitor,cn=config"
modifying entry "olcDatabase={2}hdb,cn=config"
modifying entry "olcDatabase={2}hdb,cn=config"
modifying entry "olcDatabase={2}hdb,cn=config"
modifying entry "olcDatabase={2}hdb,cn=config"
创建用户节点、组节点和数据库超级管理员
vi basedomain.ldif
dn: dc=colinlee,dc=fish
objectClass: top
objectClass: dcObject
objectclass: organization
o: Example Inc.
dc: colinlee
dn: ou=user,dc=colinlee,dc=fish
objectClass: organizationalUnit
ou: user
dn: ou=group,dc=colinlee,dc=fish
objectClass: organizationalUnit
ou: group
dn: cn=admin,dc=colinlee,dc=fish
objectClass: organizationalRole
cn: admin
description: Directory Administrator
[root@yfm18 ldap]# ldapadd -x -D cn=admin,dc=colinlee,dc=fish -W -f basedomain.ldif
Enter LDAP Password: 123456
adding new entry "dc=colinlee,dc=fish"
adding new entry "ou=user,dc=colinlee,dc=fish"
adding new entry "ou=group,dc=colinlee,dc=fish"
adding new entry "cn=admin,dc=colinlee,dc=fish"
添加一个用户
vi ldapuser.ldif
dn: uid=yuanfan,ou=user,dc=colinlee,dc=fish
objectClass: inetOrgPerson
objectClass: posixAccount
objectClass: shadowAccount
cn: yuanfan
sn: Linux
userPassword: {SSHA}C1vMXU5d5YaC2/tJKVlczBNZA9pWTBCw
loginShell: /bin/bash
uidNumber: 1000
gidNumber: 1000
homeDirectory: /home/yuanfan
dn: cn=yuanfan,ou=group,dc=colinlee,dc=fish
objectClass: posixGroup
cn: yuanfan
gidNumber: 1000
memberUid: yuanfan
[root@yfm18 ldap]# ldapadd -x -D cn=admin,dc=colinlee,dc=fish -W -f ldapuser.ldif
Enter LDAP Password:
adding new entry "uid=yuanfan,ou=user,dc=colinlee,dc=fish"
adding new entry "cn=yuanfan,ou=group,dc=colinlee,dc=fish"
在yfm17上执行
yum -y install openldap-clients nss-pam-ldapd
authconfig --enableldap --enableldapauth --ldapserver=192.168.199.118 --ldapbasedn="dc=colinlee,dc=fish" --enablemkhomedir --update
接下来用上面创建的LDAP用户登录
在yfm18上执行
yum install -y httpd
mv /etc/httpd/conf.d/welcome.conf /etc/httpd/conf.d/welcome.conf_bak
vi /etc/httpd/conf/httpd.conf
95行下面加一行
95 #ServerName www.example.com:80
96 ServerName www.walkingcloud.cn
在151行处改为
AllowOverride All
164行处改为
DirectoryIndex index.html index.php index.cgi
在最下面添加如下两行
ServerTokens Prod
KeepAlive On
systemctl start httpd
systemctl enable httpd.service
安装php
yum install php php-mbstring php-pear
systemctl restart httpd
yum --enablerepo=epel -y install phpldapadmin
vi /etc/phpldapadmin/config.php
397行取消注释,398行注释掉
$servers->setValue('login','attr','dn');
//$servers->setValue('login','attr','uid');
vi /etc/httpd/conf.d/phpldapadmin.conf
12行处添加访问的网段信息,例如192.168.199.0/24
Require ip 192.168.199.0/24
然后重启httpd服务systemctl start httpd
访问http://192.168.199.118/ldapadmin/
