三台主机分别部署LAMP

三台主机分别部署LAMP

 要求：httpd, php, mariadb分别部署在一个单独的主机上，一个虚拟主机提供phpMyAdmin，另一个虚拟主机提供wordpress，为phpMyAdmim提供https服务；

一． 分工三台主机

A  httpd主机   172.16.35.1

B  php-fpm主机 172.16.35.2

C  mariadb主机 172.16.35.3

为方便实验在这里关闭防火墙

#iptables-F

#setenforce0

安装所需rpm包：

在A上yum -y install httpd，B主机yum -y install php-fpm， C上yum -y install mariade-server php-mysql

二． httpd主机设置

1.设置vhost1.conf和vhost2.conf

[root@zq~]# vim /etc/httpd/conf.d/vhost1.conf

<VirtualHost172.16.35.1:80>

ServerNamewww1.test.com

DocumentRoot"/data/vhost/www1"

ProxyRequestson

DirectoryIndexindex.php

ProxyPassMatch^/(.*\.php)$ fcgi://172.16.35.2:9000/data/vhost/www1/$1 动态资源代理转发给第2台主机

<Directory"/data/vhost/www1">

OptionsNone

AllowOverrideNone

Requireall granted

</Directory>

</VirtualHost>

[root@zq~]# vim /etc/httpd/conf.d/vhost2.conf

<VirtualHost172.16.35.1:80>

ServerNamewww2.test.com

DocumentRoot"/data/vhost/www2"

ProxyRequestson

DirectoryIndexindex.php

ProxyPassMatch^/(.*\.php)$ fcgi://172.16.35.2:9000/data/vhost/www2/$1 动态资源代理转发给第2台主机

<Directory"/data/vhost/www2">

OptionsNone

AllowOverrideNone

Requireall granted

</Directory>

</VirtualHost>

2.修改配置文件指定NDS以及域名解析

[root@zq~]# vim /etc/resolv.conf

#Generated by NetworkManager

DNS=172.16.35.1

nameserver172.16.0.1

#本地域名解析

[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.创建静态默认文件：

[root@zq~]# mkdir -p /data/vhost/www{1,2}

[root@zq~]# vim /data/vhost/www1/index.html

<h2>zq1第1台物理机静态数据 172.16.35.1</h2>

[root@zq~]# vim /data/vhost/www2/index.html

<h2>zq2第1台物理机静态数据 172.16.35.1</h2>

4.然后测试本机静态数据是否可以正常访问

================================================================

三．php-fpm主机：

1.修改配置文件

[root@zq~]# vim /etc/php-fpm.d/www.conf

listen = 172.16.35.2:9000监听本机地址端口

listen.allowed_clients= 172.16.35.1 允许A主机连接

2.创建资源映射目录及文件

mkdir -pv/data/vhost/www{1,2}

[root@zq~]# vim /data/vhost/www1/index.php

<h2>第2台物理机a</h2>

<?php

$conn =mysql_connect('172.16.35.3','testuser','testpass');

if($conn)

echo"OK";

else

echo"Failure";

phpinfo();

?>

[root@zq~]# vim /data/vhost/www2/index.php

<h2>第2台物理机b</h2>

<?php

$conn =mysql_connect('172.16.35.3','testuser','testpass');

if($conn)

echo"OK";

else

echo"Failure";

phpinfo();

?>

3.安装加速器php-xcache

yum -yinstall php-xcache

解压wordpress以及php-myadmin分别在www1和www2中

4.修改wordpress的配置文件

[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 设置 - 具体信息来自您正在使用的主机 ** //

define('DB_NAME','qqdb');

define('DB_USER','qquser');

define('DB_PASSWORD',qqpass');

define('DB_HOST','172.16.35.3'); 这里的地址是指向第C主机的数据库地址

define('DB_CHARSET','utf8');

define('DB_COLLATE','');

5.修改phpMyAdmin的配置文件

[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']= '4pfPnDAJFPA4WMWaQxD';

随机码用！r opensslrand -base64 15 生成用于通信加密

$i = 0;

$i++;

$cfg['Servers'][$i]['auth_type']= 'cookie';

$cfg['Servers'][$i]['host']= '172.16.35.3'; $cfg['Servers'][$i]['connect_type'] = 'tcp';

$cfg['Servers'][$i]['compress']= false;

$cfg['Servers'][$i]['AllowNoPassword']= false;

四.mariadb主机

1.启动被查看数据库且设定其为开机启动

systemctlstart mariadb.service

systemctlstatus mariadb.service

systemctlenabled mariadb.service

2.授权创建用户

[root@zq ~]#mysql

mysql>GRANT ALL ON qqdb.* TO 'qquser'@'172.16.%.%' IDENTIFIED BY 'qqpass';

mysql>FLUSH PRIVILEGES;

mysql>CREATE DATABASE qqdb；

=====================================================================================

五．测试php是否可以连接数据库

http://www1.test.com/测试A主机的静态数据

http://www2.test.com/第1台主机的静态数据连接成功

http://www1.test.com/index.php第2台物理机的第一个虚拟主机的动态数据访问成功

http://www2.test.com/index.php第2台物理机的第二个虚拟主机的动态数据访问成功

http://www1.test.com/wordpress/index.php测试转发第2台主机第一个虚拟主机

http://www2.test.com/myadmin/index.php测试转发第2台主机第二个虚拟主机

六．给B主机上的php-myadmin提供https服务，详情参考单主机部署LAMP

七．压力测试

1.httpd主机的静态数据测试html：

[root@zq~]# ab-c 100 -n 1000 http://www1.test.com/data/vhost/www1/index.html 静态数据

Time perrequest: 17.254 [ms] (mean) 十次的测试数据稳定在这个数值

Time perrequest: 0.172 [ms] (mean, across all concurrent requests)

Transferrate: 2495.00 [Kbytes/sec] received

2.http主机的动态数据测试info() php：

[root@zq~]# ab -c 100 -n 1000 http://www1.test.com/data/vhost/www1/index.php

ConcurrencyLevel: 100

Timetaken for tests: 0.423 seconds

Completerequests: 1000

Failedrequests: 0

Time perrequest: 0.493 [ms] (mean, across all concurrent requests)

Transferrate: 515.33 [Kbytes/sec] received

3.测试wordpress动态数据

[root@zq~]# ab -c 100 -n 1000 http://www1.test.com/data/vhost/www1/wordpress/index.php

ConcurrencyLevel: 100

Timetaken for tests: 0.428 seconds

Completerequests: 1000

Failedrequests: 0

Writeerrors: 0

Non-2xxresponses: 1000

Totaltransferred: 226000 bytes

HTMLtransferred: 16000 bytes

Requestsper second: 2168.61 [#/sec] (mean)

Time perrequest: 47.690 [ms] (mean) 十次的测试数据稳定在这个数值

Time perrequest: 0.487 [ms] (mean, across all concurrent requests)

Transferrate: 46.59 [Kbytes/sec] received

4.动态测试myadmin数据

[root@zq~]# ab -c 100 -n 1000 http://www2.test.com/data/vhost/www2/myadmin/index.php

DocumentPath: /data/vhost/www2/myadmin/index.php

DocumentLength: 16 bytes

ConcurrencyLevel: 100

Timetaken for tests: 0.495 seconds

Completerequests: 1000

Failedrequests: 0

Writeerrors: 0

Non-2xxresponses: 1000

Totaltransferred: 226000 bytes

HTMLtransferred: 16000 bytes

Requestsper second: 2168.43 [#/sec] (mean)

Time perrequest: 45.840 [ms] (mean) 十次的测试数据稳定在这个数值

Time perrequest: 0.490 [ms] (mean, across all concurrent requests)

Transferrate: 486.59 [Kbytes/sec] received

注意对于bash来书单次接受的数据不能大于10024所以压力测试时不能把数值调的过大

5.表格：

所以用三台主机的话动态数据的响应速度会大大提高
