轻型目录存取协定(Lightweight Directory Access Protocol,LDAP)是一个开放的,中立的,工业标准的应用协议,通过IP协议提供访问控制和维护分布式信息的目录信息。GitLab、Jenkins、Nexus等都支持LDAP认证。
检查是否安装:rpm -qa | grep openldap
安装:
yum install -y openldap openldap-clients openldap-servers migrationtools
cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG
chown ldap. /var/lib/ldap/DB_CONFIG
systemctl start slapd
systemctl enable slapd
验证端口:netstat -tlnp | grep slapd
生成处理以后的管理员密码:
[root@bogon ~]# slappasswd
New password:
Re-enter new password:
{SSHA}xxxxxxxxxxxxxxxxxxxxxxxx
新建文件chrootpw.ldif
。{SSHA}xxxxxxxxxxxxxxxxxxxxxxxx为你在刚才生成的密码。
dn: olcDatabase={0}config,cn=config
changetype: modify
add: olcRootPW
olcRootPW: {SSHA}xxxxxxxxxxxxxxxxxxxxxxxx
执行ldapadd -Y EXTERNAL -H ldapi:/// -f chrootpw.ldif
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
首先要生成经处理后的目录管理者明文密码。
slappasswd
New password:
Re-enter new password:
{SSHA}xxxxxxxxxxxxxxxxxxxxxxxx
新建文件。chdomain.ldif,并把以下内容写入文件。(需要把"dc=,dc="替换成你自己的dc内容,需要把{SSHA}xxxxxxxxxxxxxxxxxxxxxxxx替换成刚才生成的密码)
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=dynamax,dc=io" read by * none
dn: olcDatabase={2}hdb,cn=config
changetype: modify
replace: olcSuffix
olcSuffix: dc=dynamax,dc=io
dn: olcDatabase={2}hdb,cn=config
changetype: modify
replace: olcRootDN
olcRootDN: cn=Manager,dc=dynamax,dc=io
dn: olcDatabase={2}hdb,cn=config
changetype: modify
add: olcRootPW
olcRootPW: {SSHA}xxxxxxxxxxxxxxxxxxxxxxxx
dn: olcDatabase={2}hdb,cn=config
changetype: modify
add: olcAccess
olcAccess: {0}to attrs=userPassword,shadowLastChange by
dn="cn=Manager,dc=dynamax,dc=io" write by anonymous auth by self write by * none
olcAccess: {1}to dn.base="" by * read
olcAccess: {2}to * by dn="cn=Manager,dc=dynamax,dc=io" write by * read
执行:ldapmodify -Y EXTERNAL -H ldapi:/// -f chdomain.ldif
再新建文件:basedomain.ldif
,并将以下内容写入。并将一些dc替换成你自己的。
dn: dc=dynamax,dc=io
objectClass: top
objectClass: dcObject
objectclass: organization
o: Dynamax
dc: Dynamax
dn: cn=Manager,dc=dynamax,dc=io
objectClass: organizationalRole
cn: Manager
description: Directory Manager
dn: ou=people,dc=dynamax,dc=io
objectClass: organizationalUnit
ou: people
dn: ou=groups,dc=dynamax,dc=io
objectClass: organizationalUnit
ou: groups
执行语句:ldapadd -x -D cn=Manager,dc=dynamax,dc=io -W -f basedomain.ldif
(注意dc之类的替换)
firewall-cmd --add-service=ldap --permanent
firewall-cmd --reload
ldapsearch -x -b "dc=dynamax,dc=io" -H ldap://192.168.118.130
选择有:phpLDAPadmin等。
