Lamp deployed on three hosts

The purpose of this experiment is to set up lamp to deploy in three hosts: one to deploy HTTP, one to deploy PHP-FPM, and one to deploy MARIADB. Prepare three hosts before deployment.

The client sends the request process:

when a client sends a static resource request, HTTPD handles it itself. When a client sends a request for a dynamic resource. HTTPD itself as a reverse proxy, sends the request to the PHP-FPM host for processing, and when the request is sent to PHP-FPM, it communicates with the mariadb when it is started (php-mysql) through MySQL and, of course, authorizes remote logins in advance.

First, the host that deploys the MARIADB

1. Installing MARIADB

Yum-y Install MariaDB

2. Start MARIADB and run the Security Wizard

Systemctl Start Mariadb.service

Mysql_secure_installation

3. Log in to MARIADB, and create a database, account, password dedicated to phpMyAdmin and WordPress, and authorize Telnet

Mysql-uroot-p

CREATE DATABASE phpdb;

CREATE DATABASE wordphp;

GRANT all on phpdb.* to ' phpuser ' @ ' 172.18.%.% ' identified by ' PHP ';

GRANT all on worddb.* to ' worduser ' @ ' 172.18.%.% ' identified by ' word ';

FLUSH privileges;

Ii. Deployment of PHP-FPM

1. Install PHP-FPM, Php-mysql

Yum-y Install PHP-FPM

Yum-y Install Php-mysql

2. Modify the PHP-FPM configuration file/etc/php-fpm.d/www.conf

Listen modified to native Ip+port

The listen.allowed_clients is set to the IP of the HTTP host.

3. Create a new directory to place phpMyAdmin and WordPress

Mkdir-pv/test/{myadmin,word}

4. Download and unzip the WordPress archive and go to the WordPress directory and copy wp-config-sample.php to wp-config.php.

Unzip Wordpress-4.3.1-zh_cn.zip

CP wp-config-sample.php wp-config.php

5. Modify the database name, account number, password, connected IP 650) this.width=650 in the wp-config.php; "Src=" http://s2.51cto.com/wyfs02/M00/7F/61/ Wkiol1ccxnkdq-nraaaqgkc4vvo501.png "title=" 3.PNG "alt=" Wkiol1ccxnkdq-nraaaqgkc4vvo501.png "style=" padding:0px; Margin:0px;vertical-align:top;border:none; "/>

6. Download and unzip the phpMyAdmin compressed package and link phpMyAdmin to PMA

config.sample.inc.php modified to config.inc.php

LN-SV phpmyadmin-4.4.14.1-all-languages PMA

CP config.sample.inc.php config.inc.php

7. Generate random numbers to fill in config.inc.php Blowfish_secret and remote database host addresses

OpenSSL rand-base64 15

Host is the IP ground for httpd

8. Installing X-cache

Yum-y Install Php-xcache

Iii. Deployment of HTTPD

1. Installing httpd

Yum-y Install httpd

2. Modify the DocumentRoot comment in the config file/etc/httpd/conf/httpd.conf file (start with #)

#DocumentRoot "/var/www/html"

3. Create two directories dedicated to static Web pages.

Mkdir-pv/test/{myadmin,word}

4. Edit the index.html in the directory where the static pages are stored

5. Create two virtual hosts, and in/etc/httpd/conf.d/create a file that ends in. conf, making the following edits

Proxyrequests represents the forward proxy, which is closed when the httpd as a reverse proxy

The proxypassmatch indicates that a matching. PHP application is destined for the PHP-FPM host.

Iv. Start-up service

Systemctl Start Httpd.service

Systemctl Start Php-fpm.service

V. Modify the Hosts file,

The domain name that we are accessing directly points to our virtual host. here take WinDOS as an example

Add a virtual host IP and domain name at C:\Windows\System32\drivers\etc\host at the end of the file

172.18.254.123 www.myadmin.com

172.18.254.123 www.word.com

Open the browser and type the address. Test results!
