1. 交换机配置（以华三交换机为例，v7版本）
   hwtacacs scheme tacacs
   primary authentication 172.18.34.45
   primary authorization 172.18.34.45
   primary accounting 172.18.34.45
   key authentication cipher $c$3$GVL2qE1HsQSyRlEI5UiDXl7Se/giCmx7fXzy
   key authorization cipher $c$3$SQRKlqv25kY6zvoAtPfqkKyr42LdnT57kh7V
   key accounting cipher $c$3$gklXXuVEMVLUcHFL0WX1t33g7BDhXciJRcb2
   user-name-format without-domain
   #
   domain hwtacacs
   authorization command hwtacacs-scheme tacacs
   accounting command hwtacacs-scheme tacacs
   authentication default hwtacacs-scheme tacacs local
   authorization default hwtacacs-scheme tacacs local
   accounting default hwtacacs-scheme tacacs local
   #
   domain default enable hwtacacs
   #
   line vty 0 15
   command authorization
   command accounting
   !
2. 用户管理平台FreeIPA安装
   系统版本 CentOS Linux release 7.3.1611 (Core)，关闭防火墙
   yum install ipa-server bind bind-dyndb-ldap
   echo "172.18.34.45 ipa.test.org ipa" >>/etc/hosts
   ipa-server-install 会自动安装全部默认回车
   https://ipa.test.org/ 安装过程中会提示用户名和输入密码，默认用户admin
   可能会遇到的报错
   如遇到messagebus服务报错，执行以下命令，然后卸载重装。
   https://bugzilla.redhat.com/show_bug.cgi?id=636876
   systemctl restart messagebus
   systemctl start certmonger
   ipa-server-install —uninstall
   ipa-server-install
   日志目录
   tail -f /var/log/dirsrv/slapd-TEST-ORG/access
   tail -f /var/log/dirsrv/slapd-TEST-ORG/errors
   设置IPA：
