The building of Linux learning Environment Ftp+dhcp+dns

A. Hardware environment:

1. Install Virtual machine VMware 10.

Create a new virtual machine, name the experiment Master, remove unnecessary devices, set the network card mode to Vnet1, and put the CentOS CD in, install the centos6.5, select the mini-install + Dev tool + server platform development.

2. Setup after the installation is complete:

1) Install the necessary tools:

cd/etc/yum.repos.d/

RM-RF./*

Vi/etc/yum.repos.d/centos.repo

[Local]name=cdrootbaseurl=file:///mntenabled=1gpgcheck=0

: Wq

Mount/dev/cdrom/mnt

RPM--import/etc/pki/rpm-gpg/*

Yum-y install wget lftp vim bind-utils man ELinks # #安装常用的软件包

2) Disable firewall and SELinux:

Chkconfig iptables off

Chkconfig Network on

Vim/etc/selinux/config

Selinux=disabled

: Wq

History-c

Poweroff

3) Take a snapshot of the virtual machine and name it clear, clone a virtual machine and name it "Ftp+dns+dhcp".

Two. Configure the FTP+DNS+DHCP virtual machine:

1) Edit the cloned virtual machine, set up the dual network card: eth0 (Vnet1 only), eth1 (bridge)

On the real machine, set the IP address for Vnet1:192.168.100.1 (vmnet1 in Network Settings), DNS: 192.168.100.100

2). Configure the IP address and the underlying settings:

[Email protected] ~]# Vi/etc/udev/rules.d/70-persistent-net.rules # #删除eth0的行, change eth1 to Eth0,eth2 to eth1

[[Email protected] ~]# IP a # #查看MAC

[[email protected] ~]# Vi/etc/sysconfig/network-scripts/ifcfg-eth0 # #编辑设置如下, MAC address must be consistent with eth1

Device=eth0hwaddr=00:0c:29:0c:b9:49type=ethernetonboot=yesnm_controlled=nobootproto=staticipaddr= 192.168.100.100netmask=255.255.255.0dns1=192.168.100.100

: Wq

[[email protected] ~]# vi/etc/sysconfig/network-scripts/ifcfg-eth1 # #新建文件, enter the following to ensure that the MAC address must be the same as eth2

Device=eth1hwaddr=00:0c:29:0c:b9:53type=ethernetonboot=yesnm_controlled=nobootproto=dhcp

: Wq

[Email protected] ~]# vi/etc/sysconfig/network

hostname=ns.linuxyy.cn

: Wq

Reboot # #重启

[Email protected] named]# vi/etc/hosts

192.168.100.100 NS ns.linuxyy.cn

: Wq

3) Configure DHCP: Note If the real machine is a Windows environment, use the command "Services.msc" to turn off the DHCP service at the beginning of the VM

Mount/dev/cdrom/mnt

Yum-y Install DHCP vsftpd bind bind-chroot

[Email protected] ~]# vim/etc/dhcp/dhcpd.conf

Option Domain-name "linuxyy.cn"; option Domain-name-servers 192.168.100.100;default-lease-time 600;max-lease-time  7200;log-facility local7;subnet 192.168.100.0 netmask 255.255.255.0 {range 192.168.100.150 192.168.100.250;  Option routers 192.168.100.100;  Next-server 192.168.100.100; FileName "pxelinux.0";}

: Wq

Vi/etc/sysconfig/dhcpd

Dhcpdargs=eth0

: Wq

/ETC/INIT.D/DHCPD restart

Chkconfig DHCPD on

NETSTAT-UTPLN |grep 67

4) Configure VSFTPD: Configuration file using default

/ETC/INIT.D/VSFTPD start

Chkconfig vsftpd on

Mkdir/var/ftp/tools

Cd/var/ftp/tools

Uploading common software packages

LS # #验证是否下载, if it has been downloaded to the real machine can be uploaded using Xshell

chmod 755/var/ftp/tools # #注意以后有什么新软件也可以下载到这个目录中, under Network Resource command "wget-p/var/ftp/tools resource URL"

Since CentOS has DVD1 and DVD2 two ISO images, use the following command to provide the client with a nearly complete Yum Source:

Mkdir/var/ftp/centos6

MOUNT/DEV/CDROM/MNT # #放入dvd -1.iso

rsync-av/mnt//var/ftp/centos6/

umount/mnt/

MOUNT/DEV/CDROM/MNT # #放入dvd -2.iso

rsync-av/mnt//var/ftp/centos6/

Access on the real machine:

FTP://192.168.100.100 # #测试是否能访问如果不能访问请检查: If the IP address of the virtual Vnet1 network card is set, can ping pass.

5) Configure DNS:

[Email protected] ~]# cd/var/named/chroot/etc/

[Email protected] etc]# vim named.conf

Options {directory "/var/named";}; Zone "linuxyy.cn." In {type master;file "Linuxyy.cn.zone";}; Zone "100.168.192.in-addr.arpa" in {type Master;file "192.168.100.arpa";};

: Wq

[Email protected] etc]# CD. /var/named/

[Email protected] named]# pwd

5) Open Snat sharing Internet:

[Email protected] ~]# iptables-t nat-i postrouting-s 192.168.100.0/24-o eth1-j Masquerade

[Email protected] ~]#/etc/init.d/iptables Save

[Email protected] ~]# sed-i '/ip_forward/s/0/1/g '/etc/sysctl.conf # #开启路由功能

[Email protected] ~]# sysctl-p

Summarize:

Configure DHCP to assign IP addresses to future experimental virtual machines, VSFTPD provides resource downloads, and DNS provides name resolution.

Do a snapshot when everything is OK.

In the future if you need to use a virtual machine, using a master clone can be cloned after the NIC to Eth0,dns set to 192.168.100.100 and other basic settings (including/etc/sysconfig/network in the host name,/etc/hosts, etc.).

Clone 8 virtual machines:

Ctos-1:192.168.100.150

Ctos-2:192.168.100.151

Ctos-3:192.168.100.152

Ctos-4:192.168.100.153

Ctos-5:192.168.100.154

Ctos-6:192.168.100.155

Ctos-7:192.168.100.156

Ctos-8:192.168.100.157

Setup steps:

1. Modify eth1== "eth0

2. Modification of yum--

Vi/etc/yum.repos.d/centos.repo

[Local]

Name=local

Baseurl=ftp://192.168.100.100/centos6

Enabled=1

Gpgcheck=0

: Wq

Reboot

History-c

>.bash_history

3.xshell Connection: Terminal modified character UTF-8, appearance setting 16 size font, color scheme.

Poweroff

4. Set a snapshot for Ctos-1-"clear

When copying a virtual machine, select: I move the VM
