之前配置Centos6.*的PXE服务器自动安装系统,最近公司需要部署Centos7.1,遇到的问题还真不少。 安装测试环境介绍: 两台物理服务器,在同一个网段,防火墙关闭,一台做pxe安装服务器,一台测试结果,网卡都有pxe引导。 pxe服务器需要安装如下组件: 1.dhcp 服务器 2.tftp 服务器 3.http 服务器(也可以是ftp nfs) 注意:dhcp服务器之监听和测试服务器相通的网卡。 pxe配置步骤: 1.安装dhcp tftp http 等安装包 yum install dhcp tftp tftp-server syslinux wget vsftpd 2.配置DHCP服务 vim /etc/dhcp.conf # # DHCP Server Configuration file. # Generate by OS install server,don't edit by hand please. # Generate at 20150915153619 # log-facility local4; ddns-update-style none; subnet 10.254.4.0 netmask 255.255.255.0 { default-lease-time 1200; max-lease-time 1200; option subnet-mask 255.255.255.0; option domain-name local; option domain-name-servers 10.254.4.250; option routers 10.254.4.250; next-server 10.254.4.250; group "local" { host compute-04-01-48.local { hardware ethernet 6c:92:bf:0c:e5:a7; option host-name "compute-04-01-48.local"; fixed-address 10.254.4.48; filename "pxelinux.0"; } } } 3.配置tftp服务器 vi /etc/xinet.d/tftp service tftp { socket_type = dgram protocol = udp wait = yes user = root server = /usr/sbin/in.tftpd server_args = -s /tftpboot/pxelinux instances = 1 per_source = 11 cps = 1000 2 flags = IPv4 disable = no } 4.设置tftp 服务器网络引导文件 mkdir -p /tftpboot/pxelinux chmod 777 /tftpboot/pxelinux cp -v /usr/share/syslinux/pxelinux. 0 /tftpboot cp -v /usr/share/syslinux/menu. c32 /tftpboot cp -v /usr/share/syslinux/memdisk /tftpboot cp -v /usr/share/syslinux/mboot. c32 /tftpboot cp -v /usr/share/syslinux/chain. c32 /tftpboot mkdir /tftpboot/pxelinux. cfg 5.挂在centos iso mount CentOS-7-x86_64-DVD-1503-01.iso /mnt/media mkdir /home/apache/centos7.1 sync -av /mnt/media /home/apache/centos7.1 6.创建kickstart文件 vim /home/apache/centos7.1/ks.cfg # Kickstart file automatically generated by anaconda. firewall --disabled install url --url http://10.254.4.46/centos7.1 #bootloader --location=mbr --driveorder=sda #clearpart --all --initlabel #clearpart --all --initlabel --drives=sda #zerombr yes selinux --disable reboot keyboard us lang en_US.UTF-8 timezone --utc Asia/Shanghai authconfig --enableshadow --enablemd5 rootpw qwe123 graphical firstboot disable network --bootproto=dhcp --device=enp8s0f0 --onboot=on #part /boot --fstype ext4 --size=1024 --ondrive=sda #part swap --size=2048 --ondrive=sda #part / --fstype ext4 --size=1 --grow --ondrive=sda bootloader location=mbr clearpart --all --initlabel part biosboot --fstype=biosboot --size=1 part swap --asprimary --fstype="swap" --size=1024 part /boot --fstype xfs --size=800 part pv.01 --size=1 --grow volgroup rootvg01 pv.01 logvol / --fstype xfs --name=lv01 --vgname=rootvg01 --size=1 --grow xconfig user --name=admin --password=123456 --homedir=/home/admin %packages @base @core @development @backup-server @directory-server @ftp-server @identity-management-server @mail-server @network-server @print-server #@system-management-messaging-server @web-server *boost* *gcc* *gdb* *cmake* *libaio-devel* *rsync* *libicu* *expect* *glibc* @virtualization* %end 7.创建pxe 菜单文件 vim /tftpboot/pxelinux. cfg/default default menu. c32 prompt 0 timeout 30 MENU TITLE unixme. com PXE Menu LABEL centos7_x64 MENU LABEL CentOS 7 X64 KERNEL vmlinuz APPEND inst.ks=http://10.254.4.46/centos7.1/ks.cfg devfs=nomount ramdisk_size=9216 inst.repo=http://10.254.4.46/centos7.1/ ksdevice=enp8s0f0 nomodeset inst.stage2=http://10.254.4.46/centos7.1/ initrd=initrd.img 8.修改http.conf 修改 DocumentRoot "/home/apache" 末尾添加: <Directory "/home/apache"> Options Indexes FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> 9.设置开机重启 chkconfig dhcpd on chkconfig xinetd on chkconfig httpd on 10.重启服务 Service httpd restart service dhcpd restart service xinetd restart 11.重启服务器,就可以进入操作系统安装 参考资料 https://fedoraproject.org/wiki/Anaconda/Kickstart/zh-cn https://github.com/rhinstaller/pykickstart/blob/master/docs/kickstart-docs.rst (责任编辑:IT) |
