一：LDAP服务器端安装
1.安装服务端
yum install -y openldap openldap-clients openldap-servers migrationtools
2.生成全局密码
slappasswd -s password -n > /etc/openldap/passwd
3.生成证书文件
openssl req -new -x509 -nodes -out /etc/openldap/certs/cert.pem -keyout /etc/openldap/certs/priv.pem -days 365
cert.pem --public key
priv.pem --private key
|--------|--------------------------------------------------------------|
|参数说明| |
|--------|--------------------------------------------------------------|
|req |PKCS#10 X.509 Certificate Signing Request (CSR) Management. |
|-new |new request. |
|-x509 |output a x509 structure instead of a cert. req. |
|-nodes |don‘t encrypt the output key |
|-out |output file. |
|-keyout |file to send the key to. |
|-days |number of days a certificate generated by -x509 is valid for. |
|-----------------------------------------------------------------------|
Generating a 2048 bit RSA private key
.............................+++
..............................................................................+++
writing new private key to ‘/etc/openldap/certs/priv.pem‘
-----
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter ‘.‘, the field will be left blank.
-----
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:BeiJing
Locality Name (eg, city) [Default City]:BeiJing
Organization Name (eg, company) [Default Company Ltd]:example
Organizational Unit Name (eg, section) []:example
Common Name (eg, your name or your server‘s hostname) []:rhel.example.net
Email Address []:root@example.com
4.设置文件权限
# chown ldap:ldap /etc/openldap/certs/*
# chmod 600 /etc/openldap/certs/priv.pem
5.生成基础数据
# cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG
# chown ldap:ldap /var/lib/ldap/*
# slaptest
会有报错，无碍:)
6.启动LDAP服务
|--------|--------------------------|
|重启服务|systemctl restart slapd |
|开机自启|systemctl enable slapd |
|检查状态|systemctl status slapd |
[root@rh1 slapd.d]# systemctl restart slapd
[root@rh1 slapd.d]# systemctl enable slapd
[root@rh1 slapd.d]# systemctl status slapd

二 配置LDAP本地服务器域
1.配置基础用户认证结构
ldapadd命令用于将LDIF文件导入到目录服务数据库中，格式为：“ldapadd [参数] LDIF文件”。
|--------|--------------------------------|
|参数 |作用 |
|--------|--------------------------------|
|-x |进行简单认证。 |
|-D |用于绑定服务器的dn。 |
|-h |目录服务的地址。 |
|-w |绑定dn的密码。 |
|-f |使用LDIF文件进行条目添加的文件。|
|--------|--------------------------------|
添加cosine和nis模块
# cd /etc/openldap/schema/
# ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f cosine.ldif
[root@rh1 slapd.d]# cd /etc/openldap/schema
[root@rh1 schema]# ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f cosine.ldif
SASL/EXTERNAL authentication started
SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth
SASL SSF: 0
adding new entry "cn=cosine,cn=schema,cn=config"
2.配置自定义的结构文件并导入到LDAP服务器
2.1 创建/etc/openldap/changes.ldif文件
dn: olcDatabase={2}hdb,cn=config
changetype: modify
replace: olcSuffix
olcSuffix: dc=example,dc=com
dn: olcDatabase={2}hdb,cn=config
changetype: modify
replace: olcRootDN
olcRootDN: cn=Manager,dc=example,dc=com
dn: olcDatabase={2}hdb,cn=config
changetype: modify
replace: olcRootPW
olcRootPW: {SSHA}2SkwaLojFlUXJZ58NSxBvwj19eXhZPUA
dn: cn=config
changetype: modify
replace: olcTLSCertificateFile
olcTLSCertificateFile: /etc/openldap/certs/cert.pem
dn: cn=config
changetype: modify
replace: olcTLSCertificateKeyFile
olcTLSCertificateKeyFile: /etc/openldap/certs/priv.pem
dn: cn=config
changetype: modify
replace: olcLogLevel
olcLogLevel: -1
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=Manager,dc=example,dc=com" read by * none
2.2 将新的配置文件更新到slapd服务程序
SASL/EXTERNAL authentication started
SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth
SASL SSF: 0
modifying entry "olcDatabase={2}hdb,cn=config"
modifying entry "olcDatabase={2}hdb,cn=config"
modifying entry "olcDatabase={2}hdb,cn=config"
modifying entry "cn=config"
modifying entry "cn=config"
modifying entry "cn=config"
modifying entry "olcDatabase={1}monitor,cn=config"
2.3 创建/etc/openldap/base.ldif文件
dn: dc=example,dc=com
dc: example
objectClass: top
objectClass: domain
dn: ou=People,dc=example,dc=com
ou: People
objectClass: top
objectClass: organizationalUnit
dn: ou=Group,dc=example,dc=com
ou: Group
objectClass: top
objectClass: organizationalUnit
2.4 创建目录的结构服务
3.将本地用户认证信息导入到LDAP服务
3.1 创建用户
# for i in $(seq -w 10)
> do
> useradd -d /home/ldapuser$i -m ldapuser$i
> echo ldapuser$i | passwd --stdin ldapuser$i
> done
3.2 帐户迁移
3.3 将当前系统中的用户和组迁移至LDAP服务
把用户信息转换成ldif文件，并导入到LDAP中
# grep "^ldapuser" /etc/passwd > /tmp/users
# /usr/share/migrationtools/migrate_passwd.pl /tmp/users /tmp/users.ldif
# ldapadd -x -w password -D cn=Manager,dc=example,dc=com -f /tmp/users.ldif
把用户组group信息转换成ldif文件，并导入到LDAP中
# grep "^ldapuser" /etc/group > /tmp/groups
# /usr/share/migrationtools/migrate_group.pl /tmp/groups /tmp/groups.ldif
# ldapadd -x -w password -D cn=Manager,dc=example,dc=com -f /tmp/groups.ldif
测试LDAP服务器上的用户认证信息
# ldapsearch -x cn=ldapuser08 -b dc=example,dc=com
[root@rh1 openldap]# ldapsearch -x cn=ldapuser08 -b dc=example,dc=com
# extended LDIF
#
# LDAPv3
# base <dc=example,dc=com> with scope subtree
# filter: cn=ldapuser08
# requesting: ALL
#
# search result
search: 2
result: 0 Success
# numResponses: 1
