Weaving Dream Lamp environment construction

1. Preface

CentOS (Community ENTerprise Operating System) is one of the Linux distributions and is compiled from Red Hat ENTerprise Linux based on source code released under open source rules. CentOS is the ideal operating system for architecture lamp (LINUX+APACHE+PHP+MYSQL) with high stability. This article takes CentOS as an example to introduce the method of installing Apache+php+mysql for Yum under Linux system.

2. Preparatory work 2.1. Log in to the server

Log on to the remote server and if your server is on-premises and installed with a desktop environment, you can also open the server desktop directly and enter Terminal manager.

Under Windows Putty is an excellent liunx telnet tool that opens the interface as follows

650) this.width=650; "Width=" height= "src="/e/u261/themes/default/images/spacer.gif "style=" Background:url (" /e/u261/themes/default/images/word.gif ") no-repeat center;border:1px solid #ddd;" alt= "Spacer.gif"/>

In the yellow box in the picture, fill in the server IP, click Open, then prompt for a user name and password, verify the successful completion of the login server.

2.2. Configure source and update system software 2.2.1. Defining Unofficial Yum Libraries

The official software is the current stable version, but not the latest version, in order to better run dedecms, we need some unofficial Yum source.

RPM--import Http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka

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

Add the following content

[Utterramblings]

Name=jason ' s utter ramblings Repo

baseurl=http://www.jasonlitka.com/media/el$releasever/$basearch/

Enabled=1

Gpgcheck=1

Gpgkey=http://www.jasonlitka.com/media/rpm-gpg-key-jlitka

[Note]vim Editor to modify the method of the file, please own Baidu

2.2.2. Updating the system

Yum Update

Yum Upgrade

2.2.3. Checking system software

Check if the current system has Apache and MySQL installed

Yum List Installed | grep httpd

Rpm-qa | grep httpd

Yum List Installed | grep MySQL

Rpm-qa | grep MySQL

If it already exists, please uninstall it first

2.3. Create a directory

Here we agree to the data storage directory as follows

Website Data/www/htdocs

Log directory/www/log

Database File/www/mysql

Run the following command to complete the directory creation

Mkdir/www/mysql

Mkdir/www/htdocs

mkdir/www/log/php

Mkdir/www/log/mysql

Add Apache and MySQL users

Useradd-s/sbin/nologin-m Apache

Useradd-s/sbin/nologin-m MySQL

The directory owner and user groups need to be changed after the directory is created, and Apache and MySQL can complete the read and write operations.

Chown-r Apache:apache/www/htdocs

Chown-r Mysql:mysql/www/mysql

Chown-r apache:apache/www/log/php

Chown-r Mysql:mysql/www/log/mysql

3. Installation and Configuration 3.1. Yum Install Apache + PHP + MySQL

Yum-y install gcc gcc-c++ autoconf make aclocal libtool expat-devel libxml2-devel httpd php php-devel MySQL mysql-server Mysql-devel libevent libevent-devel magemagick imagemagick-devel php-mysql mod_ssl mod_perl mod_auth_mysql php-mcrypt PHP-GD php-xml php-mcrypt php-mbstring php-ldap php-pear php-xmlrpc php-pecl-memcache mysql-connector-odbc Libdbi-dbd-mysql Php-eaccelerator

3.2. Configure PHP

Vi/etc/php.ini

Please change it according to your own situation, here are only some of the settings to note

Post_max_size = 32M

Memory_limit = 256M

Allow_url_fopen = On

Upload_max_filesize = 32M

Upload_tmp_dir =/var/tmp

Log_errors = On

error_reporting = e_all & ~e_notice | E_strict

Display_errors = Off

Error_log =/www/log/php/php_error.log

MAGIC_QUOTES_GPC = On

3.3. Configure Apache

Make a backup of the default configuration file first

Cp/etc/httpd/conf/httpd.conf/etc/httpd/conf/httpd.conf.bak

Edit Configuration

Vi/etc/httpd/conf/httpd.conf

Make changes according to your needs

DocumentRoot "/www/htdocs" # modified to Default Web site home directory

Namevirtualhost *:80

If you install GBK version dedecms garbled, you may need to comment out this parameter

#AddDefaultCharset UTF-8

Launch Apache Service

Service httpd Start

Check that Apache is normal, open the browser, enter http://Your IP, if you see the default Apache test page, that means the successful start.

3.4. Configure MySQL

The system has been automatically installed MySQL, but we need to do some simple modification and optimization, configuration database files and log storage location, to start.

In the/usr/share/mysql/directory there are multiple my-at the beginning of the CNF file, we can choose a use for our own situation, we choose here my-medium.cnf

Copy it into the/etc directory.

Cp/usr/share/mysql/my-medium.cnf/etc/my.cnf

Edit

Vi/etc/my.cnf

Modify the following configuration, modified on the original basis, without the option to add

[Client]

Port = 3306

Socket =/var/lib/mysql/mysql.sock

Default-character-set = UTF8

[Mysqld]

user = MySQL

DataDir =/www/mysql

Log-error =/www/log/mysql/mysql_error.log

Log-bin=/www/log/mysql/mysql-bin

Expire_logs_days=7

Character-set-server = UTF8

--skip-external-locking

Start MySQL

Service mysqld Start

The system will automatically install the initial database, and then start, if there is an error, please check the error message in/www/log/mysql/mysql_error.log

Set the MySQL root user password

Mysql

UPDATE mysql.user SET password = password (' Your password ') WHERE user = ' root ';

FLUSH privileges;

Exit

4. Optimize Settings 4.1. Security settings, disable the sensitive function of PHP

Vi/etc/php.ini

Cancel the # before disable_functions, instead

Disable_functions = exec,shell_exec,system,popen,escapeshellcmd,escapeshellarg,gzuncompress,proc_open,proc_get_ Status,show_source,gzinflate

4.2. Turn on gzip compression

Gzip compression can reduce server traffic, but also increase CPU resource consumption, whether to open you need to decide depending on the situation

Vi/etc/httpd/conf/httpd.conf

LoadModule Deflate_module modules/mod_deflate.so

<ifmodule mod_deflate.c>

Deflatecompressionlevel 6

Addoutputfilterbytype DEFLATE text/html text/plain text/xml application/x-httpd-php

Addoutputfilter DEFLATE js CSS

</IfModule>

5. Create a website

Create a Site Directory

Mkdir/www/htdocs/demo

Change the owners and groups of the following site directories

Chown-r Apache:apache/www/htdocs/demo

Configuring the Virtual Host Configuration

Vi/etc/httpd/conf/httpd.conf

At the end of the add

<virtualhost *:80>

ServerName domain name. com

Serveralias www. domain name. com

Documentroot/www/htdocs/demo

</VirtualHost>

Restart Apache

Service httpd Restart

Create a database

Mysql-u root-p

Create database demo; #demo为要创建的数据库名

Exit

Environmental construction has been completed, the following you just need to upload the DEDECMS program to/www/htdocs/demo, and your domain name resolution to your server IP, you can complete the installation of DEDECMS

Close SELinux

Close iptables
