This article mainly introduces how to build LAMP under Linux, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand.

LAMP (Linux-Apache-MySQL-PHP) website architecture is a popular international Web framework, which includes Linux operating system, Apache network server, MySQL database, Perl, PHP or Python programming language. all the products are open source software, which is a mature architecture framework in the world. Many popular commercial applications adopt this framework.

Preparatory work

System environment: centos 6.8 x86x64

[root@localhost ~] # uname-aLinux localhost.localdomain 2.6.32-642.el6.x86_64 # 1 SMP Tue May 10 17:27:01 UTC 2016 x86 "64 GNU/Linux [root@localhost] # cat / etc/redhat-releaseCentOS release 6.8 (Final) [root@localhost ~] #

Whether to install LAMP-related packages: httpd has been installed by default. Here we explain: in this experiment, we use yum to install. Httpd is the package name of Apache software in RPM.

[root@localhost] # rpm-qa httpdhttpd-2.2.15-53.el6.centos.x86_64 [root@localhost ~] # rpm-qa mysql* [root@localhost ~] # rpm-qa php* [root@localhost ~] # L-A-M-P installation

The installation of LAMP is actually very simple, with one command. Personally, I think it is not necessary for beginners to do so many plug-ins; after an in-depth understanding of LAMP, according to their own actual needs to install the module, from easy to difficult, step by step learning.

Inspection of yum warehouse

[root@localhost ~] # yum repolist\\ View the yum warehouse Loaded plugins: fastestmirror, refresh-packagekit SecurityLoading mirror speeds from cached hostfile* base: mirrors.cn99.com* extras: mirrors.cn99.com* updates: mirrors.aliyun.combase | 3.7 kB 00:00 extras | 3.4 kB 00:00 updates | | 3.4 kB 00:00 repo id repo name statusbase CentOS-6-Base 6696extras CentOS- | 6-Extras 62updates CentOS-6-Updates 482repolist: 7240

We are using centos's default network yum repository. Of course, if the default yum repository is slow, we can use epel's software package.

Yum install LAMP

We yum commands to install httpd, install mysql mysql-server and mysql-devel development packages, in the php installation package above we chose the php* command to match the php-related packages. Note that the operation is to let the beginner children's shoes first understand the scheme of LAMP, and after in-depth understanding, they still have to follow up the actual situation to install the packages needed for search.

LAMP initialization

After installing the LAMP, we need to initialize the LAMP, that is, start the service, boot and configure the necessary configuration.

Initialization of Apache

[root@localhost ~] # service httpd start\\ start the httpd service; pay attention to the relationship between httpd and apache Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain for ServerName [OK] [root@localhost ~] # chkconfig httpd on\\ set httpd launcher

Initialization of mysql

[root@localhost ~] # service mysqld start\\ start the mysql service, you will be prompted to initialize it. Very detailed Initializing MySQL database: Installing MySQL system tables...OKFilling help tables...OKTo start mysqld at boot time you have to copysupport-files/mysql.server to the right place for your systemPLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER! To do so, start the server Then issue the following commands:/usr/bin/mysqladmin-u root password' new-password'/usr/bin/mysqladmin-u root-h localhost.localdomain password' new-password'Alternatively you can run:/usr/bin/mysql_secure_installationwhich will also give you the option of removing the testdatabases and anonymous user created by default. This isstrongly recommended for production servers.See the manual for more instructions.You can start the MySQL daemon with:cd / usr; / usr/bin/mysqld_safe & You can test the MySQL daemon with mysql-test-run.plcd / usr/mysql-test; perl mysql-test-run.plPlease report any problems with the / usr/bin/mysqlbug script! [OK] Starting mysqld: [OK] [root@localhost ~] # chkconfig mysqld on\\ set mysql to boot automatically [root@localhost ~] # mysqladmin-u root password linuxprobe.com\\ initialize mysql. Here you need to set the password of the root of mysql. Command: mysqladmin-u user password password [root@localhost ~] # mysql-u root-p\\ login mysql to see if you can log in to Enter password:Welcome to the MySQL monitor. Commands end with; or\ g.Your MySQL connection id is 3Server version: 5.1.73 Source distributionCopyright (c) 2000, 2013, Oracle and/or its affiliates.

Type'\ c' to clear the current input statement.mysql >\\ ok login succeeded

Note: when yum installs lamp, php is just an integrated component of apache. There is no need to add module applications, just enable it in the configuration file.

Simple testing of the environment

Check to see if regular mysql and httpd are running:

Test the static file of httpd

Add a static index.html page for testing, or use the default page for testing. For more questions about adding web pages, please refer to "this is how linux should learn"

[root@localhost ~] # echo "hello word" > / var/www/html/index.html

Test the static page with an ie browser:

Novice must see, old bird detour-LAMP easy installation novice must see, old bird detour-LAMP easy installation

Ok, the test succeeded.

Testing of advanced environment

LAMP is a stable and dynamic website architecture solution, here we need to add php support to test dynamic websites.

Enable support for php

[root@localhost ~] # vi / etc/httpd/conf/httpd.conf [root@localhost ~] # cat / etc/httpd/conf/httpd.conf | grep DirectoryIndex\\ adds support for php page in line 402 of configuration file # DirectoryIndex: sets the file that Apache will serve if a directory

Add php test page, test

[root@localhost ~] # vi / var/www/html/index.php [root@localhost ~] # cat / var/www/html/index.php\\ Test page that adds php information [root@localhost ~] # vi / var/www/html/test.php [root@localhost ~] # cat / var/www/html/test.php\\ add php page Test testthis php test

Test:

Novice must see, old bird detour-LAMP easy installation novice must see, old bird detour-LAMP easy installation

❝

Note: dynamic web page building dynamic family forum process briefly, everyone tests Apache:httpd (service name) 80 (port) Mysql: mysqld (service name) 3306 (port, default is only for local monitoring) php: integrated in apache, only need to add php default documents enabled lamp log and other functions, it is recommended to check the relevant documents recommended to install lamp in order to make it easier to understand lamp The production environment should install impassable components according to the actual situation.

LAMP,so easy!!!
