openldap 高可用与自助修改密码部署

centos7 部署 ldap

• 需求

名称	ip地址	cpu	内存
ldap master01	10.65.10.57	4c	8G
ldap master02	10.65.91.52	4c	8G
ldap keepalived vip	10.65.91.88	4c	8G
passwd自主修改密码服务	10.65.10.56	4c	8G

jenkins、svn、rancher 等要使用统一账号密码认证，方便人员管理,因此使用ldap 用来集中认证
1.单台ldap 安装、创建用户、密码设置
2.自助密码修改服务搭建
3.高可用ldap双主keepalived 搭建使用

• 安装ldap

#关闭selinux
getenforce 
Disabled

#关闭防火墙
systemctl stop firewalld
systemctl disable firewalld

#时间同步
ntpdate  -u cn.ntp.org.cn

#安装LDAP
yum -y install openldap compat-openldap openldap-clients openldap-servers openldap-servers-sql openldap-devel migrationtools

#生成密码
slappasswd -s m2i3sc
{SSHA}opZoeJ0qVqOgpv+hEc46uDGeIwMnO4K5

#修改域、管理员信息
vim /etc/openldap/slapd.d/cn\=config/olcDatabase\=\{2\}hdb.ldif 
需要修改内容如下：
olcSuffix: dc=moviebook,dc=cn #修改dc名称
olcRootDN: cn=admin,dc=moviebook,dc=cn #修改cn名称、dc名称
olcRootPW: {SSHA}opZoeJ0qVqOgpv+hEc46uDGeIwMnO4K5 #该行为新增行，指定管理员密码，该行为新增行(新增加一行)

#修改监控文件信息
vim /etc/openldap/slapd.d/cn=config/olcDatabase={1}monitor.ldif

olcAccess: {0}to * by dn.base="gidNumber=0+uidNumber=0,cn=peercred,cn=extern
 al,cn=auth" read by dn.base="cn=admin,dc=moviebook,dc=cn" read by * none  #修改dn.base 部分，即dn.base="cn=admin,dc=moviebook,dc=cn"

#查看ldap版本号及检测
slapd -VV
slaptest -u

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

#修改ldap数据库配置目录归属用户
chown ldap:ldap -R /var/lib/ldap

#修改ldap数据库配置目录权限
chmod 700 -R /var/lib/ldap

#启动ldap
systemctl start  slapd
systemctl enable slapd
systemctl status slapd

#导入基本的数据库schema

#修改migrate_common.ph
vim /usr/share/migrationtools/migrate_common.ph

# Default DNS domain
$DEFAULT_MAIL_DOMAIN = "moviebook.cn";

# Default base 
$DEFAULT_BASE = "dc=moviebook,dc=cn";
$EXTENDED_SCHEMA = 1;

• 安装httpd

#安装httpd
yum install httpd -y

#启动httpd
systemctl start httpd
systemctl enable httpd
systemctl status httpd

• ldap 创建账号

#创建基础目录
cd /etc/openldap/
# cat 2.ldif 

dn: dc=moviebook,dc=cn
o: ldap
objectclass: dcObject
objectclass: organization
dc: moviebook

#创建目录结构
ldapadd -x -D "cn=admin,dc=moviebook,dc=cn" -W -f 2.ldif
输入admin 密码： m2i3sc

Enter LDAP Password: 
adding new entry "dc=moviebook,dc=cn"

#创建部门员工
# cat 5.ldif 
dn: ou=People,dc=moviebook,dc=cn
ou: People
objectClass: organizationalUnit

dn: cn=zhang.san,ou=People,dc=moviebook,dc=cn
ou: People
cn: zhang.san
sn: People
objectClass: inetOrgPerson
objectClass: organizationalPerson

#创建员工
# ldapadd -x -D "cn=admin,dc=moviebook,dc=cn" -W -f 5.ldif
Enter LDAP Password: 
adding new entry "ou=People,dc=moviebook,dc=cn"

adding new entry "cn=zhang.san,ou=People,dc=moviebook,dc=cn"

• 使用lam做web管理，搭建ldap account manager 管理Openldap服务

#安装php
yum install epel-release -y
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
yum -y install php72w php72w-cli php72w-fpm php72w-common php72w-devel 
systemctl enable php-fpm.service
systemctl start php-fpm.service

yum -y install php*   --skip-broken 

#报错解决
报错：rror: php72w-common conflicts with php-common-5.4.16-48.el7.x86_64
yum -y install php*   --skip-broken 

#下载安装lam
wget https://nchc.dl.sourceforge.net/project/lam/LAM/7.1/ldap-account-manager-7.1.tar.bz2  --no-check-certificate

#解压
tar jxf ldap-account-manager-7.1.tar.bz2 

#移动到httpd 目录下
mv ldap-account-manager-7.1 /var/www/html/ldap

#修改参数
cd /var/www/html/ldap/config
cp config.cfg.sample config.cfg
cp unix.conf.sample lam.conf

sed -i "s/dc=my-domain,dc=com/dc=moviebook,dc=cn/g" lam.conf
sed -i "s/cn=Manager/cn=admin/g" lam.conf
sed -i "s/dc=yourdomain,dc=org/dc=moviebook,dc=cn/g" lam.conf

#授权
chown -R apache.apache /var/www/html/ldap/

#重启httpd
systemctl restart httpd  
systemctl restart php-fpm

• 访问 lam

http://10.65.91.52/ldap

输入密码 m2i3sc

• 配置 LAM(起始登录账户非admin 需要配置，为admin 检查以下配置均可，不必配置)

#1.在登录界面选择右上角 LAM 配置
#2.选择编辑服务器配置文件
#3.密码默认为  lam
#4.General settings
  Server address: ldap://localhost:389
  Activate TLS: no
  Tree suffix:dc=moviebook,dc=cn
  LDAP search limit:-

Security settings
  Fixed list
  List of valid users: cn=admin,dc=moviebook,dc=cn
  
#5.Account types
  Users:
    LDAP suffix:ou=People,dc=moviebook,dc=cn
    List attributes:#uid;#givenName;#sn;#uidNumber;#gidNumber
  Groups:
    LDAP suffix:ou=group,dc=moviebook,dc=cn
    List attributes:#cn;#gidNumber;#memberUID;#description

• LDAP Account Manager中创建用户、创建组

#创建组
组-->新组-->增加组名（运维组）、GID编号 （10000） 以及描述信息--> 保存

#创建用户
用户-->新用户-->姓（刘三）-->电子邮件地址(xxx.q.com)--> 选择左侧ubinx --> 用户名(liu.san)-->全名（刘三）-->uid编号（10100）-->主要组(运维组)-->左上方设置密码(123456)

ldap 搭建完成,以上操作均在两台ldap master 节点上执行部署·

自助密码修改服务搭建 10.65.10.56

• 安装php 环境

#安装php
yum install epel-release -y
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
yum -y install php72w php72w-cli php72w-fpm php72w-common php72w-devel 
systemctl enable php-fpm.service
systemctl start php-fpm.service

yum -y install php*   --skip-broken 

#报错解决
报错：rror: php72w-common conflicts with php-common-5.4.16-48.el7.x86_64
yum -y install php*   --skip-broken 

• 安装httpd

#安装httpd
yum install httpd -y

#启动httpd
systemctl start httpd
systemctl enable httpd
systemctl status httpd

• 配置自助密码服务

yum install https://ltb-project.org/rpm/6Server/noarch/self-service-password-1.1-1.el6.noarch.rpm

#解析域名 changepasswd.xxx.cn 至 10.65.10.56
#登录 changepasswd.xxx.cn

• 修改密码

#打开修改密码服务，选择邮件，将会以邮件形式发送至被修改密码用户的邮箱，前提是需要在ldap 中添加用户的邮箱，比如我要修改用户王强的密码
打开邮箱，查收邮件

• 查收邮件并修改

#打开邮箱中邮件地址，修改密码
修改成功后会邮件提示修改成功

密码已成功修改~

ldap 双主高可用keepalived 部署
