在CentOS 7.7上安装FreeIPA的步骤如下:
1、系统准备
确保你的CentOS 7.7系统已经安装了必要的依赖包,打开终端,执行以下命令:
sudo yum install -y epel-release sudo yum update -y
2、安装ISC DHCP服务器
FreeIPA需要ISC DHCP服务器来为客户端分配IP地址,执行以下命令安装ISC DHCP服务器:
sudo yum install -y isc-dhcp-server
3、配置ISC DHCP服务器
编辑/etc/dhcp/dhcpd.conf
文件,添加以下内容:
subnet 192.168.1.0 netmask 255.255.255.0 { range 192.168.1.10 192.168.1.100; option domain-name-servers 8.8.8.8, 8.8.4.4; option domain-name "example.com"; option routers 192.168.1.1; default-lease-time 600; max-lease-time 7200; }
将192.168.1.0
、192.168.1.10
、192.168.1.100
、192.168.1.1
和example.com
替换为你的实际网络环境和域名。
4、启动并设置开机自启动ISC DHCP服务器
执行以下命令启动ISC DHCP服务器:
sudo systemctl start isc-dhcp-server
设置开机自启动:
sudo systemctl enable isc-dhcp-server
5、安装和配置OpenLDAP服务器
FreeIPA需要一个OpenLDAP服务器来存储用户和组信息,执行以下命令安装OpenLDAP服务器:
sudo yum install -y openldap openldap-servers openldap-clients openldap-devel
编辑/etc/openldap/slapd.conf
文件,添加以下内容:
