Demand:

CenOS 6 platform builds LAMP, in which php works as an independent service

(1) the three are separated from two hosts

(2) one virtual host is used to provide phpMyAdmin; and the other virtual host provides wordpress.

(3) install cache to provide acceleration for php

(4) mpm is prefork model.

Note:

(1) because httpd is cpu-intensive, php is io-intensive, and mariadb is both cpu-intensive and io-intensive. So we put httpd and php on a host, and mariadb on a separate host.

(2) since the CentOS 6 platform only provides mysql's rpm package, here we use the mariadb binary installation package to install.

(3) since php runs as a separate service process, the php-fpm feature should be enabled when compiling php

(4) since the versions of rpm installers for all applications provided by CentOS 6 are relatively old, they all need to be installed by compiling the source code.

(5) httpd and php need to be connected through FastCGI protocol. Httpd actually works as a reverse proxy, and proxy and proxy_cgi features need to be enabled when compiling httpd.

(6) if MPM is required to ask event model, and when php works as a module of httpd, because event is a thread model, php must enable thread safety function-- enable-maintainer-zts

Environment:

Close iptables and SELinux

Host1: as a front-end web server IP:10.0.0.61

Host2: as a backend DB server IP:10.0.0.62

Linux modification / etc/hosts/

Windows modifies C:\ Windows\ System32\ drivers\ etc

10.0.0.61 www.wordpress.com

10.0.0.61 www.phpadmin.com

Configuration:

Host2:

Install binary mariadb

# add a system user mysql [root@localhost ~] # useradd-r mysql# extract binary installation package under `/ usr/local/` directory [root@localhost ~] # tar-xf mariadb-5.5.46-linux-x86_64.tar.gz-C / usr/local/ [root@localhost ~] # cd / usr/local/# link to the `mys ql` directory [root@localhost local] # ln-sv mariadb-5.5.46-linux- X86ql64 / mysql`mysql'- > `mariadb-5.5.46-linux-x86_64/'# modify its owner and group [root@localhost local] # chown-R root:mysql mysql/# create database storage directory `/ data/ mysql` [root@localhost local] # mkdir-pv / data/mysqlmkdir: created directory` / data'mkdir: created directory `/ data/mysql'# modify its owner and group.

Host1

Test whether you can link to the database server

# because CentOS-6 does not provide mariadb, install the client of mysql. [root@localhost ~] # yum install-y mysql# test connection to HostB database [root@localhost ~] # mysql-u root-h 10.0.0.62-p

Add a new system user

# useradd-r apache

Prepare the development environment

# yum groupinstall-y "Development tools"Server Platform Development" # yum install-y pcre-devel libxml2-devel libmcrypt-devel bzip2-devel libcurl-devel
