LAMP Construction based on RPM package

1. Configuration Summary:

A) 172.16.20.10 the host runs the httpd+php service (php is the module working mode)

B) configure two virtual hosts: wordpress personal blog system, PHPmyadmin remote control mysql

C) 172.16.20.11 host running mariadb service (mysql)

two。 Configuration process:

A) configure 172.16.20.10 host: http service first

i. Installation program

1. # yum install httpd php php-mysql php-mbstring

2. Httpd provides web services

3. A module that is automatically compiled to httpd after Php installation, which is used to handle dynamic resource php scripts.

4. Php-mbstring: this package is necessary for phpMyAdmin to remotely control mysql

5. The library file package of Php-mysql:php driver mysql

B) after the installation of the Rpm package is complete, proceed to the next configuration stage:

i. Add a virtual host (FQDN-based)

1. # Vim / etc/httpd/conf.d/vhost.conf file

Add the following, FQDN-based virtual host configuration

# fixed syntax can ignore case

ServerName # is very important. FQDN-based virtual hosts must have a hostname.

DocumentRoot "/ www/host/htdoc" # virtual host root directory, path can be specified

# permission settings for the root directory of the virtual host

OptionsFollowSymLinks # FollowSymLinks indicates that symbolic link resources can be accessed

Permission settings for the require allGranted # directory

ServerNamewww.myadmin.com

DocumentRoot "/ www/host2/htdoc"

OptionsFollowSymLinks

Require allGranted

C) create the resource directory defined in the configuration file for the virtual host

I. # mkdir/www/ {host,host2} / htdoc

D) add test resources

I. # vim / www/host/htdoc/index.php

# php code to test whether php is working properly

E) match proud httpd master profile

# vim / etc/httpd/conf/httpd.conf

# find DocumentRoot "/ var/www/html" # comment it out, usually when using a virtual machine to avoid conflicts # DocumentRoot "/ var/www/html"

# add php home page index

DirectoryIndexindex.php index.html # adds index.php first, so that such resource indexes are accessed by default

# Uncomment the server name

F) start the service and test whether it is normal

# check whether the syntax of the configuration file is incorrect

# httpd-t # start the service with correct syntax

# systemctl starthttpd.service Open a web page to check whether the service is working properly

The http service test is normal, and the php module works, but, as you can see, the connection to mysql failed because we haven't configured the mysql server yet.

G) obtain wordpress and phpmyadmin

Wordpress configuration:

# download and extract to / www/host/htdoc

# cd to wordpress directory

# copy configuration file wp-config-sample.php is wp-config.php

# cpwp-config-sample.php wp-config.php

# Editing configuration file

# vimwp-config.php

Define ('DB_NAME','wpdb'); # fill in the name of the database that mysql wants to authorize (which will be configured later)

/ * * MySQL database user name * /

Define ('DB_USER','wpuser'); # enter the user name of the database

/ * * MySQL database password * /

Define ('DB_PASSWORD','wppasswd'); # enter the password for the data

/ * * MySQL host * /

Define ('DB_HOST','172.18.17.8'); # enter the ip of the mysql host

/ * default text encoding when creating a datasheet * /

Define ('DB_CHARSET','utf8')

/ * * Database collation type. If you are not sure, do not change * /

Define ('DB_COLLATE','')

Phpmyadmin configuration:

# download and extract the package to / www/host2/htdoc

# cd to the file directory

# create a symbolic connection

# ln-s phpMyAdmin-4.4.14.1-all-languages myadmin

# ls

Index.php phpMyAdmin-4.4.14.1-all-languages

Myadmin phpMyAdmin-4.4.14.1-all-languages.zip

# modify the configuration file in the cd to the myadmin directory

# cp config.sample.inc.php config.inc.php

# Editing configuration file

# vim config.inc.php

$cfg ['blowfish_secret'] =' o71mI9rimj6syc00fT3gbread; / * YOU MUST FILL IN THIS FOR COOKIE AUTH! * /

# enter a random password in single quotation marks, which can be generated using openssl rand-base64 15 (password length)

/ *

* Servers configuration

* / $I = 0

/ * * First server

, /

$iTunes +

/ * Authentication type * /

$cfg ['Servers'] [$I] [' auth_type'] = 'cookie'

/ * Server parameters * /

$cfg ['Servers'] [$I] [' host'] = '172.18.17.8; # database host ip

$cfg ['Servers'] [$I] [' connect_type'] = 'tcp'

$cfg ['Servers'] [$I] [' compress'] = false

$cfg ['Servers'] [$I] [' AllowNoPassword'] = false

H) 172.16.20.11 Host configuration: mysql service

# yuminstall mariadb-server install mysql

# systemctlstart mariadb starts mysql service

# ss-tnl view listening port. 3306 is the default port.

Perform security operations

# mysql_secure_installation

It is strongly recommended that security actions be performed after the mysql installation is complete, which makes the database more secure

Create the required database and authorize

# mysql-uroot-p

Enterpassword:

Verify database connectivity

4. Check to see if wordpress is normal
