RHEL7无人值守
DHCP+TFTP +SYSLINUX+FTP +KICKSTART
本人的linux学习笔记
5.安装 无人值守 需要的服务：DHCP+TFTP +SYSLINUX+FTP +KICKSTART
系统：rhel-server-7.0-x86_64-dvd.iso
Vmware 11
服务器：桥接vmnet0
客户机：桥接vmnet0
1. 最小化安装
2. 配置yum源
3. 安装图形化界面
4. 配置IP地址
5. 安装 无人值守 需要的服务：DHCP+TFTP+FTP+SYSLINUX+KICKSTART
6. 关闭防火墙，启动服务
先挂载镜像光盘
#mkdir /mnt/iso #创建挂载目录
#mount /dev/sr0 /mnt/iso/ #将镜像挂载到mnt的iso目录，镜像的名字在linux里是/dev/sr0
#df –TH #查看挂载情况
现在开始配置yum源
#vim /etc/yum.repos.d/hrr.repo #新建一个.repo的文件（一定要.repo）
[dvd] #yum源的名字
name=rhel7 #yum repo的描述
baselurl=file:///mnt/iso #包路径file://(特殊写法) /mnt/iso(包所在的目录必须与repodata同级目录)
enabled=1 #1启用仓库，0反之
gpgcheck=0 #1验证(后面要写gpgcheck文件在哪)，0反之
验证配置yum源结果
#yum repolist #查看yum源配置结果，可以看到status表示配置成功
# yum -y groupinstall "Server with GUI" #安装图形化界面组包
进入图形化界面
#vim /etc/sysconfig/network-scripts/ifcfg-eno16777736 #编辑网卡配置文件
修改/添加以下配置(前缀一定要大写)：
BOOTPROTO=static #static表手动配置，DHCP表自动获取
ONBOOT=yes #是否开机自动运动
IPADDR0=192.168.65.2 #IP地址
PREFIX0=24 #子网掩码
GATEWAY0=192.168.65.1 #网关
DNS1=8.8.8.8 #DNS
重启网络服务
#service network restart
查看IP配置
#nmcli connection show #查看up的网卡，name是配置文件ifcfg-后面的名字
5. 安装 无人值守 需要的服务：DHCP+TFTP +SYSLINUX+FTP +KICKSTART
#yum install -y dhcp # -y表示确认，不加y会有提示
修改DHCP配置文件
# vim /etc/dhcp/dhcpd.conf
添加/修改
subnet 192.168.65.0 netmask 255.255.255.0{ #网段
range 192.168.65.5 192.168.65.9; #范围
next-server 192.168.65.2; #TFTP服务器
filename “pxelinux.0”; #镜像名字
}
启用DHCP服务
# systemctl restart dhcpd.service
查看DHCP状态
# systemctl status dhcpd.service
# yum -y install tftp
# yum -y install tftp-server.x86_64
# yum -y install xinetd.x86_64 #xinetd是超守进程，因为TFTP是被超管理的进程，所以要用TFTP服务时，超守进程会唤醒TFTP
#vim /etc/xinetd.d/tftp #配置TFTP开机启动，把disable的yes改为no
启动服务查看状态
#service xinetd restart
#systemctl restart xinetd.service
#lsof –i:69 #69是tftp的服务端口，可以看到TFTP服务已启动
#yum –y install syslinux*
复制开机所需文件
[root@localhost /]# cd /var/lib/tftpboot/ #进入TFTP目录
[root@localhost tftpboot]# cp /usr/share/syslinux/pxelinux.0 ./ #刚刚装了sysylinux,现在将pxelinux.0镜像复制到tftpboot目录
[root@localhost tftpboot]# cp /mnt/iso/images/pxeboot/{initd.img,vmlinuxz} ./ #initd.img,内存镜像，vmlinuz是linux内核
[root@localhost tftpboot]# cp /mnt/iso/isolinux/{vesamenu.c32,*msg3} ./
[root@localhost tftpboot]#mkdir pxelinux.cfg
[root@localhost tftpboot]# cp /mnt/iso/isolinux/isolinux.cfg ./pxelinux.cfg/default #将光盘里的isolinux.cfg文件复制到tftpboot的pxelinux.cfg目录并重命名为default
查看复制结果，看到对应的6个文件，就复制成功
修改default文件
将hd:LABEL=RHEL-7.0\\x20Server.x86_64全部替换为
ftp://192.168.5.2 ks=ftp://192.168.65.2/pub/ks.cfg
一共有4个地方
#yum –y install vsftp.x86_64
[root@localhost tftpboot]# cp -r /mnt/iso/* /var/ftp #把安装光盘的文件全部复制到ftp目录
[root@localhost tftpboot]# ll /var/ftp/ #查看复制结果

启用FTP服务
# systemctl restart vsftp.service
查看DHCP状态
# systemctl status vsftpd.service
以上配置配置完就可以进行无人值守安装，不过配置是和服务器装机时的配置一样的，下面安装kickstart可以自定义安装一个不一样的系统
[root@localhost tftpboot]# yum -y install *kickstart*

#上面这些配置%post 到 %end 可以到~/ anaconda-ks.cfg那里看
配置好后保存到/var/ftp/pub/ks.cfg
测试一下：
事实证明，上面的kickstart自定义配置是没错的，可以成功的无人值守安装，而且比复制~/ anaconda-ks.cfg文件安装的要快很多，不知道为什么
为了更好的了解配置，查看/var/ftp/pub/ks.cfg(刚刚用kickstart图形界面配置)的配置文件如下:
