本次试验主要作用:

1、利用Nginx实现LNMP动静分离;

2、利用Memcache对php查询做缓存;

大致规划:

主机 IP 描述
nginx 192.168.0.111 Nginx作为代理服务器实现动静分离
php 192.168.0.112 处理动态请求
httpd 192.168.0.113 处理静态请求
mariadb 192.168.0.114 数据库存储
memcache 192.168.0.115 对php查询做缓存

一、安装配置Nginx

下载安装包:http://nginx.org/ 目前稳定版本是1.4最新

二、配置Nginx整合到php

Nginx的模块和变量相当多;这里无法一一介绍清楚;直接给出官方连接;

详细可以查阅:http://nginx.org/en/docs/     http://wiki.nginx.org/Modules

        #error_page  404              /404.html;

        location = /50x.html {
            root   html;
        }
        location ~ \.php$ {            #这里就是整合php;以.php结尾的文件
            fastcgi_pass   192.168.0.112:9000;    #以fastcgi协议代理到node2的9000端口
            fastcgi_index  index.php;         #如果没有参数;则以index.php为参数
            fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;         
            include        fastcgi_params;    #fastcgi的配置参数文件
        }
}

配置node3

[root@node3 ~]# rpm -q httpd

[root@node3 ~]# service httpd start
Starting httpd:                                            [  OK  ]
[root@node3 ~]#

配置完成后;对nginx和fpmd进行重启并提供主页面进行测试;这里现在就不测试

$mem->set('hellokey''Hello World'0600or 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.";
?>
<?php
        phpinfo();        #php测试页面
?>

wKioL1Ncx-3BeBcXAAFOl56b9Is845.jpg

上述页面显示的memcache连是正常的;且也显示该网页是来自node2.soul.com这台主机的

测试正常访问

wKiom1NchAWTmT3sAADIhf5jVtM633.jpg

测试html页面正常返回。此处也给php安装了xcache;

wKiom1NcyGqRRHE2AAEWp5oKct8810.jpg

安装过程就不再赘述;前面的博客都有详解。

到此;前面的nginx配置已完成;下面配置mariadb。

四、安装mariadb

[root@node4 ~]#
[root@node4 ~]# tar xf mariadb-10.0.10-linux-x86_64.tar.gz -C /usr/local/
#剩下步骤就是依次做个软连接到mysql
#更改权限;建议使用LVM作为存储
#存储目录权限也需要更改
#初始化
#复制启动脚本和配置文件;更改下配置文件;启动
[root@node4 ~]# mysql

可以测试php是否可以连接mariadb

[root@node2 ~]# vim /var/www/html/index.php

        if($link)
                echo "Success...";
        else
                echo "Failure...";
        mysql_close;
?>

访问测试

五、安装论坛测试

在node2,node3上各放一个论坛程序

然后访问安装

wKiom1Nc6gKzzPYEAAFov6Bkuzc326.jpg

测试安装正常。现在来看下memcache缓存的状态;

[root@node2 ~]# cd /var/www/html/

[root@node2 html]#

wKiom1Nc63jAFqniAAKXbHLdV-s885.jpg

查看memcache的详细信息;此处都有统计。

到此;memcache+lnmp已配置完成。
