LAMP refers to the first letter of Linux (operating system), Apache HTTP server, MySQL database software (sometimes MariaDB) and PHP (sometimes Perl or Python). It is generally used to set up web servers.

Linux is free and open source software, which means that the source code is available for the operating system.

Apache is the most popular open source WEB server software in use.

MySQL is a multi-thread, multi-user SQL database management system.

PHP,Perl or Python:PHP is a programming language that originally designed and produced dynamic websites. PHP is the application software mainly used on the server side. Perl is similar to Python.

Configure the yum source:

Since the yum installation is used here, the premise is that the yum source must be configured. In order to speed up the download, it is recommended to use NetEase's yum source. After we install the system, the default is the system's own yum source, domestic users use yum to install software, it is relatively slow, in order to improve efficiency, generally configure the domestic yum source.

The better yum sources in China are NetEase yum source, Sohu yum source and so on. Now introduce how to configure NetEase 163yum source:

Official link [help on using CentOS Images]: http://mirrors.163.com/.help/centos.html

The structure of the collection is: i386 ~ x86 ~ 64 ~ SRPMS

Included versions are: 5.x and 6.x series

Update time: update every 5 hours

1. Back up / etc/yum.repos.d/CentOS-Base.repo first

[root@localhost ~] # mv / etc/yum.repos.d/CentOS-Base.repo / etc/yum.repos.d/CentOS-Base.repo.$ (date+%F) _ backup

2. Choose to download the corresponding repo file according to different versions of CentOS and put it in the / etc/yum.repos.d/ directory.

[root@localhost ~] # cd / etc/yum.repos.d/

# CentOS 5.x

[root@localhost ~] # wget http://mirrors.163.com/.help/CentOS5-Base-163.repo-O / etc/yum.repo.d

# CentOS 6.x

[root@localhost ~] # wget http://mirrors.163.com/.help/CentOS6-Base-163.repo-O / etc/yum.repo.d

3. Finally, execute the yum makecache generation cache

[root@localhost ~] # yum clean all

[root@localhost ~] # yum makecache

OK, it can be configured in three simple steps.

This approach is very convenient for beginners, but the customizability is not strong, and the software version is low. It is generally used in experimental and learning environments.

Preparation:

1. Configure the firewall to open port 80 and port 3306

[root@localhost ~] # vim / etc/sysconfig/iptables

-An INPUT-m state-- state NEW-m tcp-p tcp-- dport 80-j ACCEPT # allows port 80 to pass through the firewall

-An INPUT-m state-- state NEW-m tcp-p tcp-- dport 3306-j ACCEPT # allow port 3306 to pass through the firewall

Note: many netizens add these two rules to the last line of the firewall configuration, causing the firewall to fail to start, and the correct one should be added to the default port 22 rule.

As follows:

# # #

# Firewall configuration written by system-config-firewall

# Manual customization of this file is not recommended.

* filter

: INPUT ACCEPT [0:0]

: FORWARD ACCEPT [0:0]

: OUTPUT ACCEPT [0:0]

-An INPUT-m state-- state ESTABLISHED,RELATED-j ACCEPT

-An INPUT-p icmp-j ACCEPT

-An INPUT-I lo-j ACCEPT

-An INPUT-m state-- state NEW-m tcp-p tcp-- dport 22-j ACCEPT

-An INPUT-m state-- state NEW-m tcp-p tcp-- dport 80-j ACCEPT

-An INPUT-m state-- state NEW-m tcp-p tcp-- dport 3306-j ACCEPT

-An INPUT-j REJECT-- reject-with icmp-host-prohibited

-A FORWARD-j REJECT-- reject-with icmp-host-prohibited

COMMIT

# # #

[root@localhost ~] # / etc/init.d/iptables restart # restart the firewall to make the configuration effective

2. Close SELINUX

[root@localhost ~] # vim / etc/selinux/config

# SELINUX=enforcing # comment out

# SELINUXTYPE=targeted # comment out

SELINUX=disabled # increased

: wq! # Save exit

[root@localhost] # shutdown-r now# restart the system

Installation:

First, install Apache

[root@localhost ~] # yum-y install httpd # install when prompted

[root@localhost ~] # / etc/init.d/httpd start # start Apache

Note: an error will be prompted after Apache starts:

Starting httpd:httpd: Could not reliably determine the server's fully qualif domain name, using:: 1 for ServerName

Solution:

[root@localhost ~] # vim / etc/httpd/conf/httpd.conf # Editor

Find # ServerName www.example.com:80

Change it to ServerName www.jbaobao.net:80 # and set it to your own domain name. If you don't have a domain name, you can set it to localhost.

: wq! # Save exit

[root@localhost ~] # chkconfig httpd on # is set to boot

[root@localhost ~] # / etc/init.d/httpd restart # restart Apache

Install apache related extensions

[root@localhost ~] # yum-y install httpd-manual mod_ssl mod_perl mod_auth_mysql

Type http://localhost or http:// native IP directly into the browser, and you will see the test page of Apache, where you need to pay attention to the setting of iptables.

Second, install MySQL

1. Install MySQL

[root@localhost ~] # yum-y install mysql mysql-server mysql-devel # asks if you want to install

[root@localhost ~] # / etc/init.d/mysqld start # start MySQL

[root@localhost ~] # chkconfig mysqld on # is set to boot

[root@localhost ~] # cp / usr/share/mysql/my-medium.cnf / etc/my.cnf # copy the configuration file (Note: if there is a my.cnf by default under the / etc directory, you can overwrite it directly)

2. Set the password for the root account

[root@localhost ~] # / usr/bin/mysql_secure_installation

Enter and enter Y according to the prompt

Enter the password twice and enter

Enter Y all the way according to the prompt

Last appeared: Thanks for using MySQL!

After setting the MySql password, restart MySQL:

[root@localhost ~] # / etc/init.d/mysqld start # start

[root@localhost ~] # netstat-tulpn | grep-I mysql

Tcp 0 0 0.0.0.0 3306 0.0.0.015 * LISTEN 1723/mysqld

OK, see that mysqld has been started, listening on port 3306.

Third, install PHP5

Install related modules: to make PHP support MySQL, you can install the php-mysql package; you can also use the command to search for available php modules

1. Install PHP5

[root@localhost ~] # yum-y install php # install when prompted

2. Install the common components of PHP to make PHP5 support MySQL

[root@localhost ~] # yum search php

[root@localhost ~] # yum-y install libmcrypt libjpeg* gd gd-devel php-gd php-mysql php-common php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-bcmath php-mhash # here choose to install with the above installation package

[root@localhost ~] # / etc/init.d/mysqld restart # restart MySql

[root@localhost ~] # / etc/init.d/httpd restart # restart Apche

Fourth, install Webmin

Webmin is the most powerful Unix system management tool based on Web at present. The administrator accesses various management functions of Webmin through the browser and completes the corresponding management actions.

Download the Webmin RPM package

[root@localhost ~] # wget http://prdownloads.sourceforge.net/webadmin/webmin-1.580-1.noarch.rpm

Please go to the official website to see if it is the latest version of the link. Webmin Download

Install Webmin

[root@localhost] # rpm-U webmin-1.550-1.noarch.rpm

* the following error occurred on this machine:

Header V3 DSA signature: NOKEY, key ID 11f63c51

The solution is as follows: please refer to linux Header V3 DSA signature: NOKEY, key ID error Resolution

[root@localhost ~] # rpm--import / etc/pki/rpm-gpg/RPM*

[root@localhost] # rpm-U webmin-1.550-1.noarch.rpm

Start Webmin

[root@localhost ~] # / etc/rc.d/init.d/webmin start

If you access the Webmin,Ip through the browser as: 192.168.1.63, then the URL for accessing Webmin is http://192.168.1.63:10000, the user name is: root, and the password is: root.

Configuration section
