環境 CentOS 6.7,
LDAP一般可以作為統一認證使用者身分的管理,
對IT人員來說是帳號管理的一大利器,
以下記錄這次安裝的歷程.
步驟如下:
安裝套件
如果只想裝server可以不用下openldap-clients指令
sudo yum install -y openldap-devel openldap-servers openldap openldap-clients
產生管理者密碼
sudo slappasswd
會產生一組SSHA 開頭的字串,複製起來等等設定slapd.conf會用到
複製樣板
sudo cp /usr/share/openldap-servers/slapd.conf.obsolete /etc/openldap/slapd.conf
sudo cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG
編輯ldap設定檔
sudo vi /etc/openldap/slapd.conf
#
# See slapd.conf(5) for details on configuration options.
# This file should NOT be world readable.

# Sample security restrictions
# Require integrity protection (prevent hijacking)
# Require 112-bit (3DES or better) encryption for updates
# Require 63-bit encryption for simple bind
# security ssf=1 update_ssf=112 simple_bind=64
# Sample access control policy:
# Root DSE: allow anyone to read it
# Subschema (sub)entry DSE: allow anyone to read it
# Other DSEs:
# Allow self write access
# Allow authenticated users read access
# Allow anonymous users to authenticate
# Directives needed to implement policy:
# access to dn.base="" by * read
# access to dn.base="cn=Subschema" by * read
# access to *
# by self write
# by users read
# by anonymous auth
#
# if no access controls are present, the default policy
# allows anyone and everyone to read anything but restricts
# updates to rootdn. (e.g., "access to * by * read")
#
# rootdn can always read and write EVERYTHING!
# enable on-the-fly configuration (cn=config)

by dn.exact="gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth" manage

# enable server status monitoring (cn=monitor)

修改rsyslog,增加LDAP的記錄
sudo vi /etc/rsyslog.conf
local4.* /var/log/slapd/ldap.log #隨便找個位置把這行加進去
sudo /etc/init.d/rsyslog restart
建立LDAP根路徑檔
mkdir /etc/openldap/arch
cd /etc/openldap/arch
vi arch.ldif

刪除就資料前要先停用服務
sudo service slapd stop
sudo rm -rf /etc/openldap/slapd.d/*
sudo slapadd -v -l /etc/openldap/arch/arch.ldif
以下是加入顯示的訊息
