CentOS7.6部署LDAP统一认证服务器

安装 openldap

[zhuxiaoshuai@LDAP ~]# yum install openldap openldap-clients openldap-servers migrationtools samba -y
[zhuxiaoshuai@LDAP ~]# mkdir -p /app/ldap/files/ #存放ldap相关数据文件

更改配置文件

[zhuxiaoshuai@LDAP ~]# cp /usr/share/doc/samba-4.9.1/LDAP/samba.ldif  /etc/openldap/schema/
[zhuxiaoshuai@LDAP ~]# cp /usr/share/openldap-servers/slapd.ldif  /app/ldap/files/

生成ldap的管理密码

[zhuxiaoshuai@LDAP ~]# slappasswd 

New password: 123456
Re-enter new password: 123456
{SSHA}YjzAGEYof1Ne0St5x8AzIi1YUmyNeY4d #生成的密码保存

执行命令

[zhuxiaoshuai@LDAP ~]# rm -rf /etc/openldap/slapd.d/*
[zhuxiaoshuai@LDAP ~]# slapadd -F /etc/openldap/slapd.d/ -n 0 -l /app/ldap/files/slapd.ldif
[zhuxiaoshuai@LDAP ~]# slaptest -u -F /etc/openldap/slapd.d/ #出现config file testing succeeded 代表配置文件没有问题继续执行

[zhuxiaoshuai@LDAP ~]# chown -Rv ldap.ldap /etc/openldap/slapd.d
[zhuxiaoshuai@LDAP ~]# cp /usr/share/openldap-servers/DB_CONFIG.example /var/lib/ldap/DB_CONFIG
[zhuxiaoshuai@LDAP ~]# chown -Rv ldap.ldap /var/lib/ldap/DB_CONFIG
[zhuxiaoshuai@LDAP ~]# systemctl start slapd.service

生成基本的ldap数据

[zhuxiaoshuai@LDAP ~]# vim /usr/share/migrationtools/migrate_common.ph

# Default DNS domain
 $DEFAULT_MAIL_DOMAIN = "ponfey.com";
 
 # Default base
 $DEFAULT_BASE = "dc=ponfey,dc=com";

[zhuxiaoshuai@LDAP ~]# chmod +x /usr/share/migrationtools/migrate_common.ph
[zhuxiaoshuai@LDAP ~]# /usr/share/migrationtools/migrate_base.pl > /app/ldap/files/base.ldif 
[zhuxiaoshuai@LDAP ~]# /usr/share/migrationtools/migrate_passwd.pl /etc/passwd /app/ldap/files/user.ldif
[zhuxiaoshuai@LDAP ~]# /usr/share/migrationtools/migrate_group.pl /etc/group /app/ldap/files/group.ldif

在bash.ldif和user.ldif以及group.ldif文件中删除与ldap无关的信息，之后进行数据的导入

[zhuxiaoshuai@LDAP ~]# cd /app/ldap/files/
[zhuxiaoshuai@LDAP files]# ldapadd -D "cn=Manager,dc=ponfey,dc=com" -W -x -f base.ldif
[zhuxiaoshuai@LDAP files]# ldapadd -D "cn=Manager,dc=ponfey,dc=com" -W -x -f group.ldif
[zhuxiaoshuai@LDAP files]# ldapadd -D "cn=Manager,dc=ponfey,dc=com" -W -x -f user.ldif

配置ldap日志

[zhuxiaoshuai@LDAP ~]# vi /etc/rsyslog.conf

local4.*    /var/log/ldap.log    #尾部添加

[zhuxiaoshuai@LDAP ~]# touch /var/log/ldap.log         #创建日志文件
[zhuxiaoshuai@LDAP ~]# systemctl restart rsyslog.service   重启服务
