安装配置OpenLDAP

深碍√TFBOYSˉ_ 2022-05-29 23:27 194阅读 0赞

操作系统：CentOS 6.5

### 1.防火墙和SELinux（如果已设置可直接跳过） ###

关闭SELinux

#临时关闭
    [root@localhost ~]# setenforce 0
    #永久关闭
    [root@localhost ~]# vi /etc/selinux/config
    #将SELINUX=enforcing 改为 SELINUX=disabled，然后重启机器即可

### 2.安装OpenLDAP服务 ###

#### 1.直接yum安装 ####

[root@localhost ~]# yum install -y openldap-*

#### 2.配置 ####

[root@localhost ~]# cp /usr/share/openldap-servers/slapd.conf.obsole
    te /etc/openldap/slapd.conf
    #该安装文档的目录下有这两个文件，可直接拷贝使用，slapd.conf文件也已配置好
    [root@localhost ~]# vim /etc/openldap/slapd.conf
    #该文件中的配置信息大部分与原始文件相同，不同点如下：
    #1.添加加密方式为md5加密
    password-hash {MD5}
    #2.添加日志文件等级
    loglevel 256
    #3.修改基础域
    suffix "dc=example,dc=com"
    #4.修改rootdn
    rootdn "cn=Manager,dc=example,dc=com"
    #5.修改把内存中的数据写回数据文件的操作，此处的设置表示每达到 2048K 或者10分钟执行一次 checkpoint, 即写入数据文件的操作。
    checkpoint 2048 10
    cachesize 1000 # 设置LDAP可以缓存的记录数
    #6.修改管理员密码
    rootpw 123123

改文件的内容如下：

[root@bgs-4p101-linan recognition]# cat /etc/openldap/slapd.conf |grep -v ^#
    
    
    include     /etc/openldap/schema/corba.schema
    include     /etc/openldap/schema/core.schema
    include     /etc/openldap/schema/cosine.schema
    include     /etc/openldap/schema/duaconf.schema
    include     /etc/openldap/schema/dyngroup.schema
    include     /etc/openldap/schema/inetorgperson.schema
    include     /etc/openldap/schema/java.schema
    include     /etc/openldap/schema/misc.schema
    include     /etc/openldap/schema/nis.schema
    include     /etc/openldap/schema/openldap.schema
    include     /etc/openldap/schema/ppolicy.schema
    include     /etc/openldap/schema/collective.schema
    
    allow bind_v2
    
    
    pidfile     /var/run/openldap/slapd.pid
    argsfile    /var/run/openldap/slapd.args
    
    
    
    
    TLSCACertificatePath /etc/openldap/certs
    TLSCertificateFile "\"OpenLDAP Server\""
    TLSCertificateKeyFile /etc/openldap/certs/password
    
    
    
    database config
    access to *
        by dn.exact="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth" manage
        by * none
    
    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
    
    
    database    bdb
    suffix      "dc=example,dc=com"
    checkpoint  2048 10
    rootdn      "cn=Manager,dc=example,dc=com"
    rootpw      123123
    
    directory   /var/lib/ldap
    
    index objectClass                       eq,pres
    index ou,cn,mail,surname,givenname      eq,pres,sub
    index uidNumber,gidNumber,loginShell    eq,pres
    index uid,memberUid                     eq,pres,sub
    index nisMapName,nisMapEntry            eq,pres,sub
    
    
    
    password-hash {MD5}
    loglevel 256
    cachesize 1000

#### 3.后端数据库配置 ####

[root@localhost ~]# cp /usr/share/openldap-servers/DB_CONFIG.example
    /var/lib/ldap/DB_CONFIG

#### 4.替换inetorgperson.schema文件，否则在执行初始化人员名单的时候报错。 ####

[root@localhost ~]# cd /etc/openldap/schema

替换文件，文件内容在最下面贴上去。  
![这里写图片描述][SouthEast]

#### 5.删除默认配置项 ####

[root@localhost ~]# rm -rf /etc/openldap/slapd.d/*

#### 6.配置权限（这步好像还挺重要的，之前安装完成启动失败与此处有关） ####

[root@localhost ~]# chown -R ldap:ldap /var/lib/ldap/
    [root@localhost ~]# chown -R ldap:ldap /etc/openldap/

#### 7.生成配置文件 ####

slaptest -f /etc/openldap/slapd.conf -F /etc/openldap/slapd.d -u
    #此处可能会有一个报错"bdb_db_open: database "dc=example,dc=com": db_open
    (/var/lib/ldap/id2entry.bdb) failed: No such file or directory (2)"
    #忽略即可，或者在生成配置文件命令末尾加上"-u"即可
    #生成成功的返回信息
    config file testing succeeded
    #然后重新给配置文件设置权限
    [root@localhost ~]# chown -R ldap:ldap /etc/openldap/slapd.d

#### 8.启动服务 ####

[root@localhost ~]# service slapd start

可以通过端⼝查看服务是否正常运⾏，LDAP服务运⾏端⼝是389。

![这里写图片描述][SouthEast 1]

#### 9.生成根节点 ####

此步骤必须执行，否则不能对LDAP进行任何操作，会返回一个error=32的错误。需要执行的文件在安装文档目  
录下，名为”example.ldif”。执行该文件：

ldapadd -D "cn=Manager,dc=example,dc=com" -w 123123 -x -v -f /opt/example.ldif
    # -D后加管理员dn，-w后加管理员密码，-f后加文件的存放路径及文件名

example.ldif文件内容

[root@bgs-4p101-linan ~]# cat example.ldif 
    dn: dc=example,dc=com
    objectClass: dcObject
    objectClass: organization
    dc: example
    o: rootorg

### 3、LDAP安装后，初始化组织机构和人员 ###

LDAP图形界面工具下载地址：[http://directory.apache.org/studio/downloads.html][http_directory.apache.org_studio_downloads.html]

![这里写图片描述][SouthEast 2]

操作步骤：  
1.使用LDAP图形界面工具：这里我使用的是Apache Directory Studio。  
执行第一步后用工具可查看到的如下图：
