Three hosts deploy LAMP respectively
Three hosts deploy LAMP respectively
Requirements: httpd, php, mariadb are deployed on a separate host, one virtual host provides phpMyAdmin, the other virtual host provides wordpress, and provides https services for phpMyAdmim
I. division of labor among three hosts
A httpd host 172.16.35.1
B php-fpm host 172.16.35.2
C mariadb host 172.16.35.3
Turn off the firewall here for the convenience of the experiment
# iptables-F
# setenforce0
Install the required rpm package:
Yum-y install httpd,B host yum-y install php-fpm on A, yum-y install mariade-server php-mysql on C
II. Httpd host settings
1. Set up vhost1.conf and vhost2.conf
[root@zq~] # vim / etc/httpd/conf.d/vhost1.conf
ServerNamewww1.test.com
DocumentRoot "/ data/vhost/www1"
ProxyRequestson
DirectoryIndexindex.php
ProxyPassMatch ^ / (. *\ .php) $fcgi://172.16.35.2:9000/data/vhost/www1/$1 dynamic Resource Agent forwards to the second host
OptionsNone
AllowOverrideNone
Requireall granted
[root@zq~] # vim / etc/httpd/conf.d/vhost2.conf
ServerNamewww2.test.com
DocumentRoot "/ data/vhost/www2"
ProxyRequestson
DirectoryIndexindex.php
ProxyPassMatch ^ / (. *\ .php) $fcgi://172.16.35.2:9000/data/vhost/www2/$1 dynamic Resource Agent forwards to the second host
OptionsNone
AllowOverrideNone
Requireall granted
two。 Modify the configuration file to specify NDS and domain name resolution
[root@zq~] # vim / etc/resolv.conf
# Generated by NetworkManager
DNS=172.16.35.1
Nameserver172.16.0.1
# Local domain name resolution
[root@zq ~] # vim / etc/hosts
127.0.0.1localhost localhost.localdomain localhost4 localhost4.localdomain4
:: 1localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.35.1www1.test.com www2.test.com
3. Create a static default file:
[root@zq~] # mkdir-p / data/vhost/www {1Jing 2}
[root@zq~] # vim / data/vhost/www1/index.html
Static data of the first physical machine of zq1 172.16.35.1
[root@zq~] # vim / data/vhost/www2/index.html
Static data of the first physical machine of zq2 172.16.35.1
4. Then test whether the native static data can be accessed properly.
=
3. Php-fpm host:
1. Modify the configuration file
[root@zq~] # vim / etc/php-fpm.d/www.conf
Listen = 172.16.35.2 9000 listens on the local address port
Listen.allowed_clients= 172.16.35.1 allows host A to connect
two。 Create resource mapping directories and files
Mkdir-pv/data/vhost/www {1pr 2}
[root@zq~] # vim / data/vhost/www1/index.php
The second physical machine a
[root@zq~] # vim / data/vhost/www2/index.php
The second physical machine b
3. Install Accelerator php-xcache
Yum-yinstall php-xcache
Decompress wordpress and php-myadmin in www1 and www2 respectively
4. Modify the configuration file of wordpress
[root@zq~] # cd / data/vhost/www1/wordpress/
[root@zq wordpress] # ln-s wp-config-sample.phpwp-config.php
[root@zq wordpress] # vim wp-config.php
/ / * * MySQL settings-specific information comes from the host you are using * * / /
/ * * name of WordPress database * /
Define ('DB_NAME','qqdb')
/ * * MySQL database user name * /
Define ('DB_USER','qquser')
/ * * MySQL database password * /
Define ('DB_PASSWORD',qqpass')
/ * * MySQL host * /
Define ('DB_HOST','172.16.35.3'); the address here is the database address that points to host C.
/ * 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','')
5. Modify the configuration file of phpMyAdmin
[root@zqt ~] # ln-s/data/vhost/www2/ phpMyAdmin-4.4.14.1-all-languages/data/vhost/www2/myadmin
[root@zq] # ln-s / data/vhost/www2/myadmin/config.sample.inc.php/data/vhost/www2/myadmin/config.inc.php
[root@zq ~] # vim / data/vhost/www2/myadmin/config.inc.php
$cfg ['blowfish_secret'] =' 4pfPnDAJFPA4WMWaQxDuring; / * YOU MUST FILL IN THIS FOR COOKIE AUTH! * /
Use random code! R opensslrand-base64 15 generation for communication encryption
/ *
* Serversconfiguration

$I = 0

$iTunes +
/ * Authentication type * /
$cfg ['Servers'] [$I] [' auth_type'] = 'cookie'
/ * Serverparameters * /
$cfg ['Servers'] [$I] [' host'] = '172.16.353 tcp'; $cfg [' Servers'] [$I] ['connect_type'] =' tcp'
$cfg ['Servers'] [$I] [' compress'] = false
$cfg ['Servers'] [$I] [' AllowNoPassword'] = false
IV. Mariadb host
1. Start the database being viewed and set it to boot
Systemctlstart mariadb.service
Systemctlstatus mariadb.service
Systemctlenabled mariadb.service
two。 Authorize the creation of users
[root@zq ~] # mysql
Mysql > GRANT ALL ON qqdb.* TO 'qquser'@'172.16.%.%' IDENTIFIED BY' qqpass'
Mysql > FLUSH PRIVILEGES
Mysql > CREATE DATABASE qqdb
=
5. Test whether php can connect to the database
Http://www1.test.com/ tests the static data of host A
The static data connection of the first host of http://www2.test.com/ succeeded.
The dynamic data access of the first virtual host of the second physical machine of http://www1.test.com/index.php succeeded.
The dynamic data access of the second virtual host of the second physical machine of http://www2.test.com/index.php was successful.
Http://www1.test.com/wordpress/index.php test forwards the second host and the first virtual host
Http://www2.test.com/myadmin/index.php test forwards the second host and the second virtual host
6. Provide https services to php-myadmin on host B. For more information, please see deployment of LAMP on a single host.

Note that the data accepted by bash at a time cannot be greater than 10024, so the value should not be adjusted too high during the stress test.

Do LAMP on a single host
122.684
119.658
118.152
Three hosts do LAMP
48.658
47.685
48.158
Therefore, the response speed of dynamic data will be greatly improved by using three hosts.
