拓扑如下图所示;

本次环境全部为: Centos6.5-64位;


一、先安装Mariadb数据库(编译安装与mysql的安装方法一样,此处不做详解);通用二进制格式安装;


# mkdir -pv /mydata/data/
# chown -R mysql:mysq /mydata/data/
# tar xf mariadb-10.0.10-linux-x86_64.tar.gz -C /usr/local/
# ln -sv mariadb-10.0.10-linux-x86_64 mysql
# cd mysql
# chown -R root:mysql ./*
# scripts/mysql_install_db  --user=mysql --datadir=/mydata/data/
 mkdir /etc/mysql
# cp support-files/my-large.cnf  /etc/mysql/my.cnf
# cp support-files/mysql.server /etc/init.d/mysqld
# chmod +x /etc/init.d/mysqld
# chkconfig --add mysqld
# vim /etc/mysql/my.cnf
    datadir = /mydata/data
    innodb_file_per_table = ON
#service mysqld start
# cat .my.conf
[Client]
user = ‘root‘
password = ‘redhat‘
host = ‘localhost‘
#mysql

创建一个数据库后面操作需要;
MariaDB [(none)]> create database nbadb;
MariaDB [(none)]>

 数据库安装完成,操作暂且到此;


二、编译安装Nginx;

1、在安装开始前,先装几个开发包组及创建nginx用户,组:

"Development Tools"、"Server Platform Development"、并安装"pcre-devel包"

# yum groupinstall -y "Development Tools""Server Platform Development"

# yum install pcre-devel openssl-devel zlib-devel

# groupadd -r nginx

# useradd -r -g nginx nginx


2、编译安装;


# tar xf nginx-1.4.7^C
# cd nginx-1.4.7
# ./configure   --prefix=/usr \   安装目录
  --sbin-path=/usr/local/nginx/sbin/nginx \   二进制文件存放地
  --conf-path=/etc/nginx/nginx.conf \    主配置文件存放地
  --error-log-path=/var/log/nginx/error.log \   错误日志存放地
  --http-log-path=/var/log/nginx/access.log \   访问日志存放地
  --pid-path=/var/run/nginx/nginx.pid  \    pid文件存放地
  --lock-path=/var/lock/nginx.lock \   锁文件
  --user=nginx \  nginx 用户
  --group=nginx \  nginx组
  --with-http_ssl_module \   加载ssl模块
  --with-http_flv_module \   加载流媒体模块
  --with-http_stub_status_module \  页面状态
  --with-http_gzip_static_module \  加载gzip页面压缩功能
  --http-client-body-temp-path=/var/tmp/nginx/client/ \    客户端请求主体临时目录
  --http-proxy-temp-path=/var/tmp/nginx/proxy/ \  存放代理模块的临时目录
  --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \   转发临时目录
  --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi \  
  --http-scgi-temp-path=/var/tmp/nginx/scgi \    另外一种反向代理用户请求的协议
  --with-pcre



3、为nginx提供Sysve脚本;


#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15
# description:  Nginx is an HTTP(S) server, HTTP(S) reverse #               proxy and IMAP/POP3 proxy server
# processname: nginx
# config:      /etc/nginx/nginx.conf
# config:      /etc/sysconfig/nginx
# pidfile:     /var/run/nginx.pid

        $1
        ;;

        force_reload

        rh_status

        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
        exit 2
esac


4、为脚本添加执行权限及让其开机自启动;

#chmod +x nginx
#chkconfig --add nginx
#service nginx start
#ss -tnl    查看web服务端口是否启动;
LISTEN     0      128                       *:80                       *:*      users:(("nginx",23510,6),("nginx",23512,6),("nginx",23513,6),("nginx",23514,6),("nginx",23515,6),("nginx",23516,6))

 

nginx安装完成,暂且到此;



三、安装PHP;

1、安装前先解决php所依赖一些软件包;

# yum install -y libmcrypt-devel libcurl-devel gd-devel libxm12-devel mhash-devel  libcurl-devel bzip2 bzip2-devel


2、编译安装php-5.4.26.tar.bz2;

#tar xf php-5.4.26.tar.bz2
#cd php-5.4.26
# ./configure --prefix=/usr/local/php --with-mysql=mysqlnd --with-openssl  --with-pdo-mysql=mysqlnd --with-mysqli=mysqlnd  --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr/local/libxml2/ --enable-xml  --enable-sockets --enable-fpm --with-mcrypt  --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-bz2 --with-curl
#make && make install


3、为php提供配置文件;

# cp php.ini-production /etc/php.ini


4、为php-fpm提供Sysv init脚本,并将其添加至服务列表;

# cp sapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm
# chmod +x /etc/rc.d/init.d/php-fpm
# chkconfig --add php-fpm
# chkconfig php-fpm on


5、为php-fpm提供配置文件:

# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf


6、编辑php-fpm的配置文件:配置fpm的相关选项为你所需要的值,并启用pid文件;

# vim /usr/local/php/etc/php-fpm.conf
pm.max_children = 150
pm.start_servers = 8
pm.min_spare_servers = 5
pm.max_spare_servers = 10
pid = /usr/local/php/var/run/php-fpm.pid
pm.status_path = /status
listen = 172.16.34.3:9000


7、接下来就可以启动php-fpm了:

# service php-fpm start


<h1> PHP server</h1>
<?php
        $link = mysql_connect(‘172.16.34.5‘,‘root‘,‘redhat‘);
        if ($link)
                echo "Success...";
        else
                echo "Failure...";
        mysql_close();
        phpinfo();
?>


四、安装memcached缓存服务器;

Memcached是一款开源、高性能、分布式内存对象缓存系统,可应用各种需要缓存的场景,其主要目的是通过降低对Database的访问来加速web应用程序。它是一个基于内存的“键值对”存储,用于存储数据库调用、API调用或页面引用结果的直接数据,如字符串、对象等。

memcached是以LiveJournal旗下Danga Interactive 公司的Brad Fitzpatric 为首开发的一款软件。现在

已成为mixi、hatena、Facebook、Vox、LiveJournal等众多服务中提高Web应用扩展性的重要因素。

Memcached是一款开发工具,它既不是一个代码加速器,也不是数据库中间件。其设计哲学思想主要反映在如下方面:

1. 简单key/value存储:服务器不关心数据本身的意义及结构,只要是可序列化数据即可。存储项由“键、过期时间、可选的标志及数据”四个部分组成;

2. 功能的实现一半依赖于客户端,一半基于服务器端:客户负责发送存储项至服务器端、从服务端获取数据以及无法连接至服务器时采用相应的动作;服务端负责接收、存储数据,并负责数据项的超时过期;

3. 各服务器间彼此无视:不在服务器间进行数据同步;

4. O(1)的执行效率

5. 清理超期数据:默认情况下,Memcached是一个LRU缓存,同时,它按事先预订的时长清理超期数据;但事实上,memcached不会删除任何已缓存数据,只是在其过期之后不再为客户所见;而且,memcached也不会真正按期限清理缓存,而仅是当get命令到达时检查其时长;


1、解决依赖关系;

#yum install -y libevent-devel


2、编译安装;

tar xf memcached-1.4.15.tar.gz
cd memcached-1.4.15
./configure --prefix=/usr/local/memcached --with-libevent=/usr/local/libevent
make && make instal


3、为memcached提供sysv服务启动脚本;

#vim /etc/rc.d/init.d/memcached
#!/bin/bash
#
# Init file for memcached
#
# chkconfig: - 86 14
# description: Distributed memory caching daemon
#
# processname: memcached
# config: /etc/sysconfig/memcached
. /etc/rc.d/init.d/functions
## Default variables
PORT="11211"
USER="nobody"
MAXCONN="1024"
CACHESIZE="64"
OPTIONS=""
RETVAL=0
prog="/usr/local/memcached/bin/memcached"
desc="Distributed memory caching"
lockfile="/var/lock/subsys/memcached"
start() {
        echo -n $"Starting $desc (memcached): "
        daemon $prog -d -p $PORT -u $USER -c $MAXCONN -m $CACHESIZE -o "$OPTIONS"
        RETVAL=$?
        [ $RETVAL -eq 0 ] && success && touch $lockfile || failure
        echo
        return $RETVAL
}
stop() {
        echo -n $"Shutting down $desc (memcached): "
        killproc $prog
        RETVAL=$?
        [ $RETVAL -eq 0 ] && success && rm -f $lockfile || failure
        echo
        return $RETVAL
}
restart() {
        stop
        start
}
reload() {
        echo -n $"Reloading $desc ($prog): "
        killproc $prog -HUP
        RETVAL=$?
        [ $RETVAL -eq 0 ] && success || failure
        echo
        return $RETVAL
}
case "$1" in
  start)
        start
        ;;
  stop)
        stop
        ;;
  restart)
        restart
        ;;
  condrestart)
        [ -e $lockfile ] && restart
        RETVAL=$?
        ;;     
  reload)
        reload
        ;;
  status)
        status $prog
        RETVAL=$?
        ;;
   *)
        echo $"Usage: $0 {start|stop|restart|condrestart|status}"
        RETVAL=1
esac
exit $RETVAL


4、为脚本添加执行权限及添加至开机自启动;

chmod +x /etc/init.d/memcached
chkconfig --add memcached
service memcached start

   启动时报如下错误;俱体原因不详;但是找到了解决办法;

bubuko.com,布布扣

/usr/local/memcached/bin/memcached -d -m 1024 -p 11211 -u root

bubuko.com,布布扣


5、使用telnet测试是否可以连接成功;如下图

bubuko.com,布布扣


五、在php-fpm服务器上安装mamcache扩展;

1、编译安装memcache-2.2.6.tgz;

# tar xf memcache-2.2.6.tgz
# cd memcache-2.2.6
# /usr/local/php/bin/phpize     执行命令,让php识别这个模块
Configuring for:
PHP Api Version:         20100412
Zend Module Api No:      20100525
Zend Extension Api No:   220100525
# ./configure --with-php-config=/usr/local/php/bin/php-config --enable-memcache
# make && make install


2、上述安装完后会有类似以下的提示:

bubuko.com,布布扣


3、编辑etc/php.ini,在“动态模块”相关的位置添加如下一行来载入memcache扩展:

#  vim /etc/php.ini    打开php的配置文件,添加如下项;
extension = /usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/memcache.so
#  service php-fpm restart

bubuko.com,布布扣


4、而后对memcached功能进行测试,在网站目录中建立测试页面memcache.php,添加如下内容:

vim /usr/local/nginx/html/test.php

<?php
$mem = new Memcache;
$mem->connect("172.16.34.2", 11211)  or die("Could not connect");
$version = $mem->getVersion();
echo "Server‘s version: ".$version."<br/>\n";
$mem->set(‘hellokey‘, ‘Hello World‘, 0, 600) or die("Failed to save data at the memcached server");
echo "Store data in the cache (data will expire in 600 seconds)<br/>\n";
$get_result = $mem->get(‘hellokey‘);
echo "$get_result is from memcached server.";
?>


5、测试其功能是否正常工作;

六、对前端代理nginx操作,实现动静分离;

1、修改配置;vim /etc/nginx/nginx.conf

worker_processes  5;      进程个数
events {
    worker_connections  1024;    每个worker进程能够响应的最大请求数
}
http {
    include       mime.types;      支持多媒体类型
    default_type  application/octet-stream; 
    sendfile        on;    由内核转发
    keepalive_timeout  5;     持久连接时间
    gzip  on;    压缩功能
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
    server {
        listen       80;
        server_name  www.ouyang.com;
        add_header X-via $server_addr;
        location / {
                root    html;
                index   index.php       index.html      index.html;
        }
        location ~* \.(jpg|jpeg|png|gif|js|css)$ {
            root   html;
        }
        location ~ \.php$ {
            root           html;
            fastcgi_pass   172.16.34.3:9000;   代理后端动态php服务器
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
            include        fastcgi_params;
        }
}


2、编辑/etc/nginx/fastcgi_params,将其内容更改为如下内容;

#fastcgi_params
fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx;
fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;
fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;


3、重启nginx服务;

[root@ou nginx]# service nginx restart
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
Stopping nginx:                                            [  OK  ]
Starting nginx:                                            [  OK  ]


4、动静分离测试;

1、在后端php服务器/usr/local/nginx/html目录下创建index.php(在前端代理服务器相同的路径下也需要一份),由于前端代理服务要响应静态内容的页面,因此在放入一张图片,用于测试;后端就不需

# cd /usr/local/nginx/html/
[root@ou html]# pwd
/usr/local/nginx/html
50x.html  index.html  index.php  nba.jpg


[root@php html]# pwd
/usr/local/nginx/html
[root@php html]# ls
index.php

2、写入如下内容,用于测试;vim index.php

<h1> PHP server</h1>
<?php
        $link = mysql_connect(‘172.16.34.5‘,‘root‘,‘redhat‘);
        if ($link)
                echo "Success...";
        else
                echo "Failure...";
        mysql_close();
        phpinfo();
?>

由于本次实验没有做DNS域名解析,因此需要把www.ouyang.com域名写入到win7的hosts文件当中;C:\Windows\System32\drivers\etc\hosts

# localhost name resolution is handled within DNS itself.
#   127.0.0.1       localhost
#   ::1             localhost
172.16.34.1     www.ouyang.com


3、现在即可测试;

静态页面;

bubuko.com,布布扣

动态测试;数据库也连接成功;

bubuko.com,布布扣


七、安装wordpress前端nginx和后端的php都需要安装wordpress),配置一样;

cd /usr/local/nginx/html
# unzip wordpress-3.3.1-zh_CN.zip
# cd wordpress
# cp wp-config-sample.php wp-config.php
# vim wp-config.php
define(‘DB_NAME‘, ‘nbadb‘);
/** MySQL 数据库用户名 */
define(‘DB_USER‘, ‘root‘);
/** MySQL 数据库密码 */
define(‘DB_PASSWORD‘, ‘redhat‘);
/** MySQL 主机 */
define(‘DB_HOST‘, ‘172.16.34.5‘);
/** 创建数据表时默认的文字编码 */
define(‘DB_CHARSET‘, ‘utf8‘);
/** 数据库整理类型。如不确定请勿更改 */
define(‘DB_COLLATE‘, ‘‘);


bubuko.com,布布扣

ok!


八、安装memadmi-master监控memcached状态(前端代理与php都要安装memadmin-master)两端操作一样;

#cd /usr/local/nginx/html
#unzip memadmin-master.zip


bubuko.com,布布扣

bubuko.com,布布扣

bubuko.com,布布扣

bubuko.com,布布扣


九、在前端设置前端代理的缓存功能;

fastcgi模块的常用指令;
   fastcgi_pass;指定fastcgi服务监听端口、地址、也支持使用Unix sock;
   fastcgi_bind;指定联系fpm服务时使用的地址

   fastcgi_param;定义传递给fpm服务器的参数


   结果可以缓存,缓存空间使用proxy_cache_path定义,使用fastcgi_cache来调用
   fastcgi_cache_path;   调用定义好的缓存名称
   fastcgi_cache_valid;     可以定义多个;
   fastcgi_connect_timeout;连接fastcgi服务器的超时时长
   fastcgi_send_timeout;向fastcgi服务传输数据的超时时长


没有定义缓存的测试如果;# ab -n 1000 -c 100 http://www.ouyang.com/

bubuko.com,布布扣


定义vim /etc/nginx/nginx.conf

bubuko.com,布布扣

再次测试;# ab -n 1000 -c 100 http://www.ouyang.com/
