Linux from getting started to mastering--enterprise network installation

# # # #企业网络安装 # #

Purpose: Deploy servers in bulk

Share files over the network via TFTP

On the server side:
To install and configure a DHCP configuration file
Systemctl Stop Firewalld # #特别重要, turn it off.
Yum Install Dhcp-y
Cp/usr/share/doc/dhcp-4.2.5/dhcp.conf.example/etc/dhcp/dhcpd.conf

　　　　　　

Vim dhcpd.conf
# #27和28以及35行以后删除
# #195 option Domain-name "student.com" domain name
# #196 option Domain-name-servers 114.114.114.114 DNS
# #default-lease-time 600 default lease period
# #max-lease-time 7200 Maximum lease period

# #subnet 172.25.254.0 netmask 255.255.255.0 {subnet settings
Range 172.25.254.160 172.25.254.200; IP address Pool
Option routers 172.25.254.250; Gateway
}

　　　　　　

On the client:
Because you want to get Ip,gw,dns from the server and the files that require client access, the client is set to DHCP

　　　　　　

On the server side:
To share (provide) your file pxelinux.0 file, you'll need to download syslinux-4.05-8.e17.x86_64
Yum Install Syslinux-4.05-8.e17.x86_64-y
Yum Install Tftp-server.x86_64-y # #用的网络服务是tftp
Netstat-antlupe | grep xinetd # #端口没有开启
Vim/etc/xinetd.d/tftp
Disable = no
Sysemctl Restart Xinetd.server
Netstat-antlupe | grep xinetd #端口开启了

　　　　　　

　　　　　　

The default distribution directory for TFTP is:/var/lib/tftpboot
cp/usr/share/syslinux/pxelinux.0/var/lib/tftpboot/
Mkdir/var/lib/tftpboot/pxelinux.cfg
Access to the installation interface, but the point option is not available because there is no default file

grep "Install Red Hat"-R # #显示installred had is which directory to read

On The real machine :
MOUNT/ISO/RHEL7.0/MNT # #将7.0 Mirroring Mount then read
Cd/mnt
Cd/isolinux
Scp-r *[email Protected]:/var/lib/tftpboot
On the server side:
Cd/var/lib/tftpboot
LS # #会出现当才拷贝的文件
　　　　　　

Because the default is to access the Pxelinux.cfg/default file, create a
CP isolinux.cfg Pxelinux.cfg/default # #因为isolinux这个文件是最初的那个界面
Systemctl Restart Xinetd.service

Vim/etc/dhcp/dhcpd.conf
# #27和28以及35行以后删除

# #subnet 172.25.254.0 netmask 255.255.255.0 {subnet settings
Range 172.25.254.160 172.25.254.200; IP address Pool
Option routers 172.25.254.250; Gateway
Next-server 172.25.254.110; # #引导访问下面的文件
FileName "pxelinux.0"
}

Change the wait time and default title, background map, big title:
Change the contents of a Pxelinux.cfg/default file
Cd/var/lib/tftpboot
Vim Pxelinux.cfg/default
Timeout # #更改等待时间
　　　　　　

# #在label Linux and label check, change the following to Linux
Menu Default # #更改光标默认位置
　　　　　　

Menu title Westos Install OS # #更改大标题
Menu Background Xxx.png # #更改背景图

Attach point: Change the pixels of a picture
File Splash.png # #查看背景的像素
Splash.png:PNG image data, 640x480,1-bit colormap,non-interlaced
Convert liuyan.png-resize 640x480!liu.png # #更改照片的像素

Add a mirror and auto-install script that can install virtual machines
On the real machine:
mount/xxx/xxx.iso/var/www/html/rhel7.0 # #挂载到默认读取目录上
　　　　　　

Cd/var/lib/tftpboot
Vim Pxelinux.cfg/default
Append initrd=initrd.imgrepo=http://172.25.254.10/rhel7.0 quit (does not show intermediate process)
　　　　　　

Yum Install System-config-kickstart-y # #下载自动安装
System-config-kickstart # #编辑ks. cfg file
Ksvalidator ks.cfg # #查看检测ks. CFG If there is a syntax error
　　　　　　

Cd/var/lib/tftpboot
Vim Pxelinux.cfg/default
Append initrd=initrd.imgrepo=http://172.25.254.10/rhel7.0 quit (does not show intermediate process) ks=http://172.25.254.110/ks.cfg

Note: Remember to open the HTTPD service, I did not open at the beginning, and then the installation will be error, no files
