二 环境信息

(一)操作系统

    [root@prod001 ~]# lsb_release -a
    LSB Version:    :core-4.1-amd64:core-4.1-noarch:cxx-4.1-amd64:cxx-4.1-noarch:desktop-4.1-amd64:desktop-4.1-noarch:languages-4.1-amd64:languages-4.1-noarch:printing-4.1-amd64:printing-4.1-noarch
    Distributor ID: CentOS
    Description:    CentOS Linux release 7.6.1810 (Core)
    Release:        7.6.1810
    Codename:       Core
    [root@prod001 ~]# rpm -qa | grep ldap
    openldap-2.4.44-21.el7_6.x86_64
    [root@prod001 ~]#

(二)软件信息

openldap-2.4.44
完整的需要安装以下4个软件
openldap
openldap-clients
openldap-servers
migrationtools

三 实施

(一) 软件安装

使用yum 源安装即可

    [root@prod001 ~]# yum install -y openldap openldap-clients openldap-servers migrationtools

安装成功后,信息如下

    Running transaction
      Installing : openldap-servers-2.4.44-21.el7_6.x86_64                                                                  1/3

    Installed:
      migrationtools.noarch 0:47-15.el7  openldap-clients.x86_64 0:2.4.44-21.el7_6  openldap-servers.x86_64 0:2.4.44-21.el7_6

    Complete!

(二)配置

3.2.1 slappasswd生产密码

    [root@prod001 ~]# slappasswd
    New password:
    Re-enter new password:
    {SSHA}rFw4xTIEAVrlKB1yI95HlEqzTv2FMWWq
    [root@prod001 ~]#

记住该密码:
rFw4xTIEAVrlKB1yI95HlEqzTv2FMWWq
此处对应的明文密码是:123456
PS(同一台机器同一个明文密码在不同的时间生成的密文是不一样的)

3.2.2 备份/etc/openldap

    [root@prod001 etc]# tar -zcvf openldap.20200211.tgz openldap/^C
    [root@prod001 etc]# ls *.tgz
    openldap.20200211.tgz  openldap.tgz
    [root@prod001 etc]#

3.2.3 编辑/etc/openldap/slapd.d/cn=config/olcDatabase={2}hdb.ldif

    # AUTO-GENERATED FILE - DO NOT EDIT!! Use ldapmodify.
    # CRC32 1fb9123b
    dn: olcDatabase={2}hdb
    objectClass: olcDatabaseConfig
    objectClass: olcHdbConfig
    olcDatabase: {2}hdb
    olcDbDirectory: /var/lib/ldap
    olcSuffix: dc=biwei,dc=art
    olcRootDN: cn=Manager,dc=biwei,dc=art
    olcRootPW: {SSHA}rFw4xTIEAVrlKB1yI95HlEqzTv2FMWWq
    olcDbIndex: objectClass eq,pres
    olcDbIndex: ou,cn,mail,surname,givenname eq,pres,sub
    structuralObjectClass: olcHdbConfig
    entryUUID: b4232b36-e10b-1039-89ba-adc38f9f2334
    creatorsName: cn=config
    createTimestamp: 20200211111633Z
    entryCSN: 20200211111633.060093Z#000000#000#000000
    modifiersName: cn=config
    modifyTimestamp: 20200211111633Z

olcSuffix: dc=biwei,dc=art #修改成自己的域名
olcRootDN: cn=Manager,dc=biwei,dc=art #修改成自己的域名
olcRootPW: rFw4xTIEAVrlKB1yI95HlEqzTv2FMWWq #增加的密码

3.2.4 修改/etc/openldap/slapd.d/cn=config/olcDatabase={1}monitor.ldif


    [root@prod001 etc]# vim /etc/openldap/slapd.d/cn\=config/olcDatabase\=\{1\}monitor.ldif
    # AUTO-GENERATED FILE - DO NOT EDIT!! Use ldapmodify.
    # CRC32 2c600cd6
    dn: olcDatabase={1}monitor
    objectClass: olcDatabaseConfig
    olcDatabase: {1}monitor
    olcAccess: {0}to * by dn.base="gidNumber=0+uidNumber=0,cn=peercred,cn=extern
     al,cn=auth" read by dn.base="cn=Manager,dc=biwei,dc=art" read by * none
    structuralObjectClass: olcDatabaseConfig
    entryUUID: b423280c-e10b-1039-89b9-adc38f9f2334
    creatorsName: cn=config
    createTimestamp: 20200211111633Z
    entryCSN: 20200211111633.060012Z#000000#000#000000
    modifiersName: cn=config
    modifyTimestamp: 20200211111633Z

olcAccess: {0}to * by dn.base="gidNumber=0+uidNumber=0,cn=peercred,cn=extern
al,cn=auth" read by dn.base="cn=Manager,dc=biwei,dc=art" read by * none
此处改为您对应的域名

3.2.5 准备LDAP数据库

    cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG

3.2.6 测试前面修改的配置文件是否正确

    [root@prod001 etc]# slaptest -u
    5e429330 ldif_read_file: checksum error on "/etc/openldap/slapd.d/cn=config/olcDatabase={1}monitor.ldif"
    5e429330 ldif_read_file: checksum error on "/etc/openldap/slapd.d/cn=config/olcDatabase={2}hdb.ldif"
    config file testing succeeded
    [root@prod001 etc]#

3.2.7 修改权限

    [root@prod001 etc]#  chown ldap:ldap -R /var/lib/ldap
    [root@prod001 etc]#  chmod 700 -R /var/lib/ldap
    [root@prod001 etc]#

不做这一步 ,下面启动可能会报 没有读写权限
错误如下

    Feb 11 19:46:30 prod001 runuser[26192]: pam_unix(runuser:session): session opened for user ldap by (uid=0)
    Feb 11 19:46:30 prod001 runuser[26192]: pam_unix(runuser:session): session closed for user ldap

    Feb 11 19:46:30 prod001 systemd[1]: slapd.service failed.

3.2.8 设置开机启动

    [root@prod001 etc]# systemctl start slapd
    [root@prod001 etc]# systemctl status slapd
    ● slapd.service - OpenLDAP Server Daemon
       Loaded: loaded (/usr/lib/systemd/system/slapd.service; disabled; vendor preset: disabled)
       Active: active (running) since Tue 2020-02-11 19:49:50 CST; 7s ago
         Docs: man:slapd
               man:slapd-config
               man:slapd-hdb
               man:slapd-mdb

    [root@prod001 etc]# systemctl enable slapd
    Created symlink from /etc/systemd/system/multi-user.target.wants/slapd.service to /usr/lib/systemd/system/slapd.service.
    [root@prod001 etc]#

3.2.9 执行 ldapsearch -x -b '' -s base'(objectclass=*)' 测试

 
    [root@prod001 etc]# ldapsearch -x -b '' -s base'(objectclass=*)'
    # extended LDIF
    #
    # LDAPv3
    # base <> with scope baseObject
    # filter: (objectclass=*)
    # requesting: ALL
    #

    #
    dn:
    objectClass: top
    objectClass: OpenLDAProotDSE

    # search result
    search: 2
    result: 0 Success

    # numResponses: 2
    # numEntries: 1
    [root@prod001 etc]#

3.2.10 将所有的配置LDAP server, 添加到LDAP schemas中

    cd /etc/openldap/schema/ 

    ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f core.ldif  
    ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f cosine.ldif  
    ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f inetorgperson.ldif 
    ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f nis.ldif  
    ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f collective.ldif  
    ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f corba.ldif    
    ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f duaconf.ldif  
    ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f dyngroup.ldif      
    ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f java.ldif  
    ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f misc.ldif  
    ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f openldap.ldif  
    ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f pmi.ldif  
    ldapadd -Y EXTERNAL -H ldapi:/// -D "cn=config" -f ppolicy.ldif

检查下上面每行命令的执行结果。

3.2.11 使用 Migration Tools to 创建LDAP DIT

    [root@prod001 schema]# cd /usr/share/migrationtools/
    [root@prod001 migrationtools]# cp migrate_common.ph migrate_common.ph.bak.orig
    [root@prod001 migrationtools]#

主要修改下面几行,请修改成您对应的域名

    71 $DEFAULT_MAIL_DOMAIN = "biwei.art";
    74 $DEFAULT_BASE = "dc=biwei,dc=art";
    90 $EXTENDED_SCHEMA = 1;

3.2.12 建立基本条目,用于生成用户上级的ou 信息

    [root@prod001 migrationtools]# cd /usr/share/migrationtools/
    [root@prod001 migrationtools]# ./migrate_base.pl> /root/base.ldif
    [root@prod001 migrationtools]# ll /root/base.ldif
    -rw-r--r-- 1 root root 2007 Feb 11 20:04 /root/base.ldif
    [root@prod001 migrationtools]#

ldapadd -x -W -D "cn=Manager,dc=biwei,dc=art" -f /root/base.ldif

    这句命令 我注意
    cn=Manager,dc=biwei,dc=art 要与4.2.2 里一致,否则会报密码不对。
    [root@prod001 migrationtools]# ldapadd -x -W -D "cn=Manager,dc=biwei,dc=art" -f /root/base.ldif
    Enter LDAP Password:
    adding new entry "dc=biwei,dc=art"

    adding new entry "ou=Hosts,dc=biwei,dc=art"

    adding new entry "ou=Rpc,dc=biwei,dc=art"

    adding new entry "ou=Services,dc=biwei,dc=art"

    adding new entry "nisMapName=netgroup.byuser,dc=biwei,dc=art"

    adding new entry "ou=Mounts,dc=biwei,dc=art"

    adding new entry "ou=Networks,dc=biwei,dc=art"

    adding new entry "ou=People,dc=biwei,dc=art"

    adding new entry "ou=Group,dc=biwei,dc=art"

    adding new entry "ou=Netgroup,dc=biwei,dc=art"

    adding new entry "ou=Protocols,dc=biwei,dc=art"

    adding new entry "ou=Aliases,dc=biwei,dc=art"

    adding new entry "nisMapName=netgroup.byhost,dc=biwei,dc=art"

    [root@prod001 migrationtools]#
