Lamp Separation Deployment

1. Host Planning

There are at least 3 virtual machines in the configuration, and the operating system is CentOS network segment in 172.16.27.0/16

The allocation is as follows:

1 httpd Server 172.16.27.20

1 PHP-FPM Server 172.16.27.30

1 db Server 172.16.27.40

2. Working mode

First, the client initiates the request, the request divides into 2 kinds, one kind is the static request it can directly by the Apache direct response return; the other is the dynamic request, such as contains in PHP or Perl this kind of script explanatory language, By the Apache server through the FASTCGI protocol call PHP Server execution and return to Apache returned by Apache to explain the results of execution, if the process involves the operation of the data, the PHP server will also call the MySQL server through the MySQL protocol.

3. Compile and install Apache (172.16.27.20)

Pre-deployment preparation

Yum Groupinstall "Development Tools"

Yum Install Apr-util-devel

Yum Install Pcre-devel openssl-devel libevent-devel

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

Start extracting httpd and compiling

[Email protected] tmp]# TAR-VXF httpd-2.4.6.tar.bz2

[Email protected] tmp]# CD httpd-2.4.6/

[Email protected] httpd-2.4.6]#/configure--prefix=/usr/local/apache--sysconfdir=/etc/httpd24-- Enable-so--enable-ssl--enable-cgi--enable-rewrite--enable-modules=most--enable-mpms-shared=all--with-mpm= Prefork--with-pcre--with-zlib--with-apr=/usr--with-apr-util=/usr

[[email protected] httpd-2.4.6]# make-j 2 && make install

[[email protected] local]# ln-sv apache2.4.6/apache (create soft connection)

Create users and groups for Apache

[Email protected] local]# groupadd-g Apache

[Email protected] local]# useradd apache-u 800-g 800-m-s/sbin/nologin

Creating Mailbox File:file exists

[[email protected] local]# ID Apache

uid=800 (Apache) gid=800 (Apache) groups=800 (Apache)

Launch Apache Service

[Email protected] local]# cat/etc/profile.d/httpd.sh

Export Path=/usr/local/apache/bin: $PATH

[[email protected] local] apachectl start

Enter the IP address in the browser to access, show it works on behalf of our HTTPD server has been built. (Turn off firewall and SELinux)

4 Compiling and installing Php+xcache (172.16.27.30)

(1) Compile and install PHP

Resolving PHP dependencies

# yum Install libxml2-devel gd-devel freetype-devellibmcrypt-devel openssl-devel bzip2 bzip2-devel

Compiling and installing php5.5

# Tar XF php-5.5.30.tar.gz

Add php.ini and PHP-FPM files

(1) Provide a configuration file for PHP

Copy the Php.ini-production file from the php-5.5.30 unpacking package

# Cp/tools/php-5.5.30/php.ini-production/etc/php.ini

Providing configuration files for PHP-FPM

# CD php5.5/etc/

# CP Php-fpm.conf.defaultphp-fpm.conf

Configuring the PHP-FPM File

[Email protected] php5.5]# vim etc/php-fpm.conf

PID = Run/php-fpm.pid

listen= 172.16.27.30:9000

listen.allowed_clients= 172.16.27.20 #web服务器地址

Pm.max_children = 1024

Pm.start_servers = 16

Pm.min_spare_servers = 5

Pm.max_spare_servers = 20

Pm.process_idle_timeout = 15s

Pm.max_requests = 2048

Start the PHP-FPM service

(1) Setting the PATH environment variable

# cat/etc/profile.d/php-fpm.sh

Export path=/data/soft/php5.5/sbin/: $PATH

(2) Provide startup script for PHP-FPM

# CP/TOOLS/PHP-5.5.30/SAPI/FPM/INIT.D.PHP-FPM/ETC/INIT.D/PHP-FPM

# chmod +X/ETC/INIT.D/PHP-FPM

# chkconfig--add php-fpm

# Chkconfig PHP-FPM on

(3) Start php-fpm, view the number of PHP-FPM processes

# service PHP-FPM Start

# Ps-ef |grep-c php-fpm

Set up Apache virtual host to connect PHP

Configuring Apache Support fcgi

[Email protected] ~]# vim/etc/httpd24/httpd.conf

LoadModule Proxy_module modules/mod_proxy.so

LoadModule proxy_fcgi_modulemodules/mod_proxy_fcgi.so

(5) Editing a virtual host (172.16.27.20)

<virtualhost *:80>

ServerAdmin [email protected]

DocumentRoot "/DATA/VHOST/WWW1"

ServerName ww1.ssl.com

Errorlog "/data/vhost/www1/www1.errorlog"

Customlog "/data/vhost/www1/www1.customlog" combined

Proxyrequests off #关闭正向代理

Proxypassmatch ^/(. *.php) $ fcgi://172.16.27.30:9000/var/vhost/www1/$1

6 to improve the performance of PHP installation XCache

# TAR-XVF XCACHE-3.2.0.TAR.BZ2

# CD xcache-3.2.0

#./configure--enable-xcache--with-php-config=/data/soft/ph

# Make && Makeinstall

# Ls/data/soft/php-5.5.30/lib/php/extensions/no-debug-non

Consolidate PHP and XCache, copy xcache configuration files to php.d directory, enable PHP to read XCache configuration files

# MKDIR/ETC/PHP.D

# CP Xcache.ini/etc/php.d/

Edit the/etc/php.d/xcache.ini file to specify the location of the xcache.so

# sed-n ' 4p '/etc/php.d/xcache.ini

Extension =/data/soft/php-5.5.30/lib/php/extensions/no-debug-non-zts-20121212/xcache.so

Deploying MARIADB Services

Using MySQL binary installation mode

Create MySQL users and groups

# groupadd-g 306 MySQL

# useradd-u 306-g mysql-s/sbin/nologin-m MySQL

Decompression mariadb-5.5.46-linux-x86_64.tar.gz

# Tar XF mariadb-5.5.46-linux-x86_64.tar.gz-c/data/soft/

# LN-SV MARIADB-5.5.46-LINUX-X86_64/MARIADB

' Mariadb ', ' mariadb-5.5.46-linux-x86_64/'

Create MySQL Data directory and authorize

Mkdir/data/mydata-p

Chown-r Mysql.mysql/data/mydata

Initializing the database file

# Chown-r root.mysql/data/soft/mariadb/

# CD/DATA/SOFT/MARIADB

# Scripts/mysql_install_db--user=mysql--datadir=/data/mydata/--basedir=/data/soft/mariadb

Configuring the MARIADB Master profile my.cnf

Copy the my-large.cnf file under the/data/soft/mariadb/support-files directory to the/etc/directory, overwriting the original MySQL configuration file my.cnf (Note: You need to manually back up before overwriting):

# CP SUPPORT-FILES/MY-LARGE.CNF/ETC/MY.CNF

Modify the/etc/my.cnf file, specify the DataDir, Basedir path, and open port 3306

[Mysqld]

Port = 3306

Basedir =/data/soft/mariadb

DataDir =/data/mydata

innodb_file_per_table = 1 #让innodb表每个表一个表空间文件.

Copy MySQL startup script to/etc/init.d/mysqld

# Cp/data/soft/mariadb/support-files/mysql.server/etc/init.d/mysqld

# chmod 755/etc/init.d/mysqld

Modifying the PATH environment variable

[Email protected] mariadb]# cat/etc/profile.d/mysql.sh

Export MYSQL_HOME=/DATA/SOFT/MARIADB

Export path= $mysql _home/bin: $PATH

Start the MySQL service

[Email protected] mariadb]# chkconfig--add mysqld

[Email protected] mariadb]# chkconfig mysqld on

[[Email protected] mariadb]# service mysqld start

Starting MySQL ... success!

Enter the PHP host to edit the contents of the index.php file as follows:

<?php

$link =mysql_connect (' 172.16.27.40 ', ' WordPress ', ' WordPress ');

if ($link) {

echo "success. Wordpress! ";

}else{

echo "failed. Wordpress! ". Mysql_error ();

}

Mysql_close ($link);

Phpinfo ();

?>

Success appears. frank! success, if the failure to see the cause of failure to carry out the relevant operation!

Remember to turn off the firewall!

(10) Configuration phpMyAdmin

Create a folder in either the Frank directory or a random virtual host directory on the PHP host and the HTTP host

For example, in a directory on a PHP host

Unzip Phpmyadmin-4.4.10-all-languages.zip

Can. The two hosts operate the same.

The next step is to configure the phpMyAdmin on the PHP host.

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

Vim config.inc.php

Mainly found

$cfg [' Servers '] [$i] [' Host ']= ' 172.16.27.40 ' IP address of the database server

$cfg [' blowfish_secret '] = ' 77777 '; Here the characters are arbitrary, this is primarily to distinguish between cookies.

Then restart the services on the three hosts to test.
