This article mainly introduces "deployment and testing of PXE service environment". In daily operation, I believe many people have doubts about the deployment and testing of PXE service environment. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "deployment and testing of PXE service environment"! Next, please follow the editor to study!

PXE server deployment environment, testing

PXE server

1. The supporting software needed by the PXE server: DHCP, TFTP, syslinux (providing pxe bootstrap file pxelinux.0), file sharing (nfs, ftp, http, samba) and so on.

2. Deployment of PXE server: DHCP TFTP syslinux vsftpd

Close selinux and firewalld

Deploy DHCP server 1. Check software: rpm-Q dhcp 2. Installation software: yum install-y dhcp 3. Check the configuration file: rpm-qc dhcp 4. Edit the dhcp.conf configuration file vim / etc/dhcp/dhcp.conf 5. Start the dhcp service, which allows you to start systemctl restart/enable/status dhcp restart automatically | self-boot | status systemctl-atunlp | grep: 67

3. PXE client test

1. Create a new virtual machine named pxe0

two。 The memory setting of the virtual machine needs to be set to at least 1300m.

3. Create a snapshot.

4. Start the virtual machine, get the IP address, but get stuck in a certain interface

4. Deploy tftp-server server

1. Check software: rpm-Q tftp-server

two。 Installation: yum install-y tftp-server

3. Check the configuration: rpm-qc tftp-server

/ etc/xinted.d/tftp

4. Edit tftp profile

Disable = yes in vim / etc/xinted.d/tftp change yes to no

5. Start the tftp service, allowing boot to start automatically.

6. Install the syslinux software that provides pxelinux.0 and share the pxe bootstrapper file

1.yum install-y syslinux mlocate

two。 Share the files you made to the / var/lib/tftpboot directory

DNS server

Forward and reverse parsing of dns server, auxiliary dns server

Forward resolution: domain name-"IP address"

Reverse resolution: IP address-"domain name"

Positive 1. Install software: bind, bind-utils

two。 Check the configuration file: / etc/named.conf

3. Modify DNS configuration file / etc/named.conf (backup first)

4. Configure forward resolution zone information: named.rfc1912.zones (backup first)

5. Do DNS internal test (local test) after restarting the service

Systemctl restart named

Nslookup & server & & server 192.168.11.11 & & Domain name (www.baidu.com)

DNS view:

/ etc/named.conf

Eg:

Acl dianxin {defines the access control list name as dianxin Telecom

192.168.10.0amp 24; specify the network address and subnet mask, 24 is the subnet mask of 255.255.255.0

}

View "dianxin" {defines the view name as dianxin Telecom

Match-clients {dianxin;}; the network segment of the matching client is dianxin (that is, the name defined by acl)

Recursion yes; enables recursive query

Zone "test.com" IN {Register test.com matching configuration

Type master; type is master primary DNS server

File "dianxin.test.com.zone"; parsing resource profile for the zone

}

}

# zone "." IN {

Type hint;file "named.ca"

#}

# include "/ etc/named.rfc1912.zones"

# include "/ etc/named.root.key"

# the following is the new content to be added

Acl dianxin {

192.168.10.0/24

}

View "dianxin" {

Match-clients {dianxin;}

Recursion yes

Zone "test.com" IN {

Type master

File "dianxin.test.com.zone"

}

Apache Overview:

Is a web website server software. Used to publish website information resources. Provide web services to users.

Work port: TCP 80

Service type: services managed by systemd

Software name: httpd

Package name:

Server package: httpd-2.4.6-45.el7.centos.x86_64.rpm

Development tool: httpd-devel-2.4.6-45.el7.centos.x86_64.rpm

Help manual: httpd-manual-2.4.6-45.el7.centos.noarch.rpm

Tool package: httpd-tools-2.4.6-45.el7.centos.x86_64.rpm (including ab, htpasswd commands)

Files and directories for apache

Working directory: / etc/httpd

Default home page directory: / var/www/html description: there is no index.html home page by default and needs to be created manually.

Configuration file directory: / etc/httpd/conf

Main configuration file: / etc/httpd/conf/httpd.conf

* additional configuration file directory: / etc/httpd/conf.d

Default welcome test page: / etc/httpd/conf.d/welcome.conf

Local help File Home Page: file:///usr/share/httpd/manual/index.html

How it works:

1. Connection process: through the input URL, the customer uses the HTTP protocol to establish a connection with the server through TCP covering his hand three times.

two。 Request process: request the home page resources of the website from the server, usually the default home page is index.html, index.php, index.jsp and other file names.

3. Reply process: the server transmits the home page file to the client browser. If the home page does not exist, it will show that the page does not exist

4. Close connection: in order to avoid taking up server resources all the time, the TCP connection will be closed automatically after data transfer.

Implementation ideas

1. Turn off the firewall and Selinux.

2. Install the software httpd on the apache server.

3. Set the httpd.conf configuration file and start the httpd service.

4. The client accesses the web server (apache).

5. Operation and maintenance management of apache: view the log files of the apache server.
