标签:nginx mysql php memcached


传统上基于进程或线程模型架构的web服务通过每进程或每线程处理并发连接请求,这势必会在网络和I/O操作时产生阻塞,其另一个必然结果则是对内存或CPU的利用率低下。生成一个新的进程/线程需要事先备好其运行时环境,这包括为其分配堆内存和栈内存,以及为其创建新的执行上下文等。这些操作都需要占用CPU,而且过多的进程/线程还会带来线程抖动或频繁的上下文切换,系统性能也会由此进一步下降。 

在设计的最初阶段,nginx的主要着眼点就是其高性能以及对物理计算资源的高密度利用,因此其采用了不同的架构模型。受启发于多种操作系统设计中基于事件的高级处理机制,nginx采用了模块化、事件驱动、异步、单线程及非阻塞的架构,并大量采用了多路复用及事件通知机制。在nginx中,连接请求由为数不多的几个仅包含一个线程的进程worker以高效的回环(run-loop)机制进行处理,而每个worker可以并行处理数千个的并发连接及请求。 

如果负载以CPU密集型应用为主,如SSL或压缩应用,则worker数应与CPU数相同;如果负载以IO密集型为主,如响应大量内容给客户端,则worker数应该为CPU个数的1.52倍。 

Nginx会按需同时运行多个进程:一个主进程(master)和几个工作进程(worker),配置了缓存时还会有缓存加载器进程(cache loader)和缓存管理器进程(cache manager)等。所有进程均是仅含有一个线程,并主要通过共享内存的机制实现进程间通信。主进程以root用户身份运行,而workercache loadercachemanager均应以非特权用户身份运行。 

主进程主要完成如下工作: 
1. 读取并验正配置信息; 
2. 创建、绑定及关闭套接字; 
3. 启动、终止及维护worker进程的个数; 
4. 无须中止服务而重新配置工作特性; 
5. 控制非中断式程序升级,启用新的二进制程序并在需要时回滚至老版本; 
6. 重新打开日志文件,实现日志滚动; 
7. 编译嵌入式perl脚本; 

worker进程主要完成的任务包括: 
1. 接收、传入并处理来自客户端的连接; 
2. 提供反向代理及过滤功能; 
3. nginx任何能完成的其它任务; 

cache loader进程主要完成的任务包括: 
1. 检查缓存存储中的缓存对象; 
2. 使用缓存元数据建立内存数据库; 

cache manager进程的主要任务: 
1. 缓存的失效及过期检验; 

Nginx的配置有着几个不同的上下文:mainhttpserverupstreamlocation(还有实现邮件服务反向代理的mail)。配置语法的格式和定义方式遵循所谓的C风格,因此支持嵌套,还有着逻辑清晰并易于创建、阅读和维护等优势。 
Nginx的代码是由一个核心和一系列的模块组成, 核心主要用于提供WebServer的基本功能,以及WebMail反向代理的功能;还用于启用网络协议,创建必要的运行时环境以及确保不同的模块之间平滑地进行交互。不过,大多跟协议相关的功能和某应用特有的功能都是由nginx的模块实现的。这些功能模块大致可以分为事件模块、阶段性处理器、输出过滤器、变量处理器、协议、upstream和负载均衡几个类别,这些共同组成了nginxhttp功能。事件模块主要用于提供OS独立的(不同操作系统的事件机制有所不同)事件通知机制如kqueueepoll等。协议模块则负责实现nginx通过httptls/sslsmtppop3以及imap与对应的客户端建立会话。 

nginx内部,进程间的通信是通过模块的pipelinechain实现的;换句话说,每一个功能或操作都由一个模块来实现。例如,压缩、通过FastCGIuwsgi协议与upstream服务器通信,以及与memcached建立会话等。 

配置nginx作为web_Server使用

安装nginx

# mkdir  /data/software  -pv

# cd/data/software/

# wget http://nginx.org/download/nginx-1.6.2.tar.gz

安装之前先安装一些基本的库和依赖包

# yum install gccgcc-c++  openssl-devel pcre pcre-develzlib zlib-devel

创建web用户:

# groupadd  -r nginx

# useradd  -r -g nginx -s /bin/false  -M nginx

# tar zxvfnginx-1.6.2.tar.gz

# cd nginx-1.6.2

# ./configure \

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

配置fpm的相关选项为你所需要的值,并启用pid文件(如下最后一行):

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(这个参数可以不用)

# service php-fpmstart

# lsof -i :9000

整个PHP5nginx

Nginx vim/etc/nginx/nginx.conf

启用以下选项:

location ~ \.php${

            root           html;

            fastcgi_pass   127.0.0.1:9000;

            fastcgi_index  index.php;

            fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;

            include        fastcgi_params;

        }

# cat/etc/nginx/fastcgi_params

fastcgi_paramGATEWAY_INTERFACE CGI/1.1;

fastcgi_paramSERVER_SOFTWARE nginx;

fastcgi_paramQUERY_STRING $query_string;

fastcgi_paramREQUEST_METHOD $request_method;

fastcgi_paramCONTENT_TYPE $content_type;

fastcgi_paramCONTENT_LENGTH $content_length;

fastcgi_paramSCRIPT_FILENAME $document_root$fastcgi_script_name;

fastcgi_paramSCRIPT_NAME $fastcgi_script_name;

fastcgi_paramREMOTE_PORT $remote_port;

fastcgi_paramSERVER_ADDR $server_addr;

fastcgi_paramSERVER_PORT $server_port;

fastcgi_paramSERVER_NAME $server_name;
并在所支持的主页面格式中添加php格式的主页,类似如下:

location / {

root html;

index index.phpindex.html index.htm;

}

创建测试页面:

# mkdir -pv/website/data

# cat >>/website/data/index.php <<EOF

> <?

> phpinfo();

> ?>

> EOF

Nginx.conf修改

        location / {

            root   /website/data;

            index  index.php index.html index.htm;

        }

备注:这里遇到以下问题:


问题1
52055#0: *1 FastCGI sent in stderr: "Primary script unknown" whilereading response header from upstream

将:
fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;

改为:
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
nginx识别不到/scripts路径,所以phpinfou验证信息无法正成通过。改成如上就是:$document_root就是针对/website/data目录下的php文件进行解析。

问题2

一切正常之后发现phpininfo的页面为空白页

修改vim /etc/php.ini

short_open_tag =On
访问一切正常:

安装xcache,为PHP加速

# cd/data/software/

# wget http://xcache.lighttpd.net/pub/Releases/3.2.0/xcache-3.2.0.tar.gz

# tar zxvfxcache-3.2.0.tar.gz

# cd xcache-3.2.0

#/usr/local/php/bin/phpize

#./configure  --enable-xcache--with-php-config=/usr/local/php/bin/php-config

# make &&make install

# mkdir -p/etc/php.d
# cp xcache.ini  /etc/php.d/
# vim /etc/php.d/xcache.ini
extension = /usr/local/php/lib/php/extensions/no-debug-non-zts-20121212/xcache.so

指定具体的路径

# service php-fpmrestart

bubuko.com,布布扣

 

 

Nginx虚拟主机的配置:

server {

     listen    8080;

     server_name localhost;

     location /bbs {

           root /website;

           index index.html index.htmindex.php;

           }

    error_page 404 /404.html;

    location = /404.html {

           root /website/bbs;

           }

}

这里定义了一个虚拟主机,访问:
http://xxx.xxx.xxx.xxx:8080/bbs,实际访问的是:
http://xxx.xxx.xxx.xxx:8080/website/bbs目录


404错误页面重定向,可以隐藏版本信息,正常页面如下:
bubuko.com,布布扣需要在HTTP区域开启:
fastcgi_intercept_errors on; 选项
然后在server中配置好:
error_page     404 /404.html;

location =/404.html {

        root /website/bbs;

       }

bubuko.com,布布扣
error_page     404 /404.html;

error_page       502 503 504 /50x.html;

error_page       403 http://xxx.xxx.xxx.xxx/forbidden.html;

# error_page   404 =@fetch;

location =/404.html {

        root /website/bbs;

       }

 

 

Upstream 模块

Upstream backup {

         Server www.xxx.com weight=5;

         Server www.xxx.com :8080

         Server www.xxx.com down; #所有服务器挂了之后,会把请求交给此服务器

         Ip_hash; #开启回话保持机制

}

这里nginx支持三种会话机制:

         Round-robin

         Ip_hash

         Least_conn

 

配置nginx做反向代理服务器

这里需要两台web node1 node2

配置nginx配置文件:

HTTP区域定义:
    upstream webserver {

        server 172.16.100.101:80 weight=1;

        server 172.16.100.102:80 weight=1;

     }

server {

        listen       80;

        server_name  localhost;

        location / {

             proxy_pass http://webserver;

        }

}

# nginx –t&& service nginx restart

bubuko.com,布布扣


bubuko.com,布布扣

实现负载均衡

URL重写

如下:

Server {

         Listen 8080

         Server_name localhost

         Location / {

                   Root html

                   Index index.html;

                   Rewrite^/bbs/(.*)$ http://172.16.100.101/form/$1;

}

Error_page 404/404.html;

Localtion =/404.html {

Root html;

}

}

确保后端可以正常访问:
bubuko.com,布布扣

IE访问:
http://172.16.100.128:8080/bbs/

bubuko.com,布布扣

bubuko.com,布布扣

server {

         listen 8080;

         server_name localhost;

         location / {

                root html;

                index index.html index.htmindex.php;

                rewrite^/bbs/(.*)$ /forum/$1;

                }

    }

访问http://172.16.100.128:8080/bbs/ 跳转到http://172.16.100.128:8080/forum

Bbs目录不存在,这里是实现的是本机跳转。

 

Last :本次重写完成,重启协下一轮检查

Break:本次重写结束后,直接后续操作

 

 

常用指令使用:
alias 指令:

         Location /bbs/ {

         alias /website/bbs/;

         index index.html index.htm;

}
访问http://xxx.xxx.xxx.xxx/bbs/index.html重定向到
http://xxx.xxx.xxx.xxx/website/bbs/index.html

Location指令:

         Location /bbs/ {

         Root /website/;
         index index.html index.htm;

}

访问http://xxx.xxx.xxx.xxx/bbs/ 实际访问是

http://xxx.xxx.xxx.xxx/website/bbs

注意两者的区别

 

HTTP access 模块:

 

 

 

 

Nginx缓存机制:

nginx 缓存:

        cache:共享内存,存储键和缓存对象元数据

                        磁盘空间,存储数据

        proxy_cache_path    不能定义在server{}

缓存目录,子目录级别

proxy_cache_path/nginx/cache/first level=1:2:1 keys_zone=first:20m max_size=1G;

 

cache_managerLRU

 

配置如下:

HTTP区域配置:
http {

proxy_cache_path/nginx/cache/first levels=1:2:1 keys_zone=first:20m max_size=1g;

}

Server {

add_header X-Cache "$upstream_cache_status from$server_addr";

location  / {

                             proxy_pass http://webserver;

             proxy_set_header Host      $host;

             proxy_set_header X-Real-IP$remote_addr;

             proxy_cache first;

             proxy_cache_valid 200 10m

}

}

 

bubuko.com,布布扣

 

另外三个常用的缓存:

Open_log_cache:日志缓存

Open_file_cache

Fastcgi_cache

 

 

压缩功能:

gzip on;
gzip_min_lenght      1000;
gzip_proxied    expired no-cache no-storeprivate auth;
gzip_types        text/plain          application/xml;

 

 

 

nginx 实现动静分离

 

upstream phpsrvs{

server 172.16.100.101:80 weight=1;

server 172.16.100.102:80 weight=1;

}

Upstream imgsrvs{

         Server 172.16.100.103:80 weight=1;

         Server 172.16.100.103:80 weight=1;

}

http {

server {

                   location / {

         root/web/htdocs;
                   index index.phpindex.html;

}

                   Location ~*\.php${

         Fastcgi_passhttp://phpsrvs;

}

Location ~*”\.(jpg|jpeg|jif|png)$” {

         Proxy_passhttp://imgsrvs;

动态修改使用内存:

# cat/etc/sysconfig/memcached

PORT="11211"

USER="nobody"

MAXCONN="1024"

CACHESIZE="128"

OPTIONS=""

编辑/etc/init.d/memcached

## Defaultvariables

PORT="11211"

USER="nobody"

MAXCONN="1024"

CACHESIZE="64"

OPTIONS=""

[ -f/etc/sysconfig/memcached  ] && ./etc/sysconfig/memcached

此行即可

安装memcachedphp扩展

# cd /data/software/
# wget http://pecl.php.net/get/memcache-2.2.7.tgz
# wget https://codeload.github.com/junstor/memadmin/zip/master

# tar zxvfmemcache-2.2.7.tgz
# cd memcache-2.2.7
# /usr/local/php/bin/phpize
# ./configure --with-php-config=/usr/local/php/bin/php-config  --enable-memcache
# make && make install
# cat /etc/php.d/memcache.ini

extension =/usr/local/php/lib/php/extensions/no-debug-non-zts-20121212/memcache.so

[root@localhostmemcache-2.2.7]#

# service php-fpm restart

测试php使用memcached

# cat/website/data/test.php

<?php

$mem = newMemcache;

$mem->connect("127.0.0.1",11211)  or die("Could notconnect");

 

$version =$mem->getVersion();

echo"Server‘s version: ".$version."<br/>\n";

 

$mem->set(‘testkey‘,‘Hello World‘, 0, 600) or die("Failed to save data at the memcachedserver");

echo "Storedata in the cache (data will expire in 600 seconds)<br/>\n";

 

$get_result =$mem->get(‘testkey‘);

echo"$get_result is from memcached server.";        

?>

[root@localhostmemcache-2.2.7]#

证明PHP程序已经可以使用memcached

 

Nginx 整个memcached

    upstream webserver {

        server 172.16.100.101:80 weight=1;

        server 172.16.100.102:80 weight=1;

     }

    server {

        listen       80;

        server_name  localhost;

        location / {

             set $memcached_key $uri;

             memcached_pass 127.0.0.1:11211;

             default_type text/html;

             error_page 404 @fallback;

        }

        location @fallback {

                proxy_pass http://webserver;

                proxy_set_header Host      $host;

                proxy_set_header X-Real-IP$remote_addr;

        }

配置memadmin-master

# unzipmemadmin-master.zip
# mv memadmin-master /website/data/memadmin

配置memcached缓存mysqld数据

Memcached MySQL都已经安装完成

CREATE DATABASEmem_test;

USE men_test;

CREATE TABLE mem( id int(7) NOT NULL AUTO_INCREMENT, name char(8) DEFAULT NULL, PRIMARY KEY(id) ) ENGINE=innodb AUTO_INCREMENT=10 DEFAULT CHARSET=utf8;

INSERT INTOmem  VALUES(1,‘tome‘),(2,‘james‘),(3,‘jack‘),(4,‘mary‘),(5,‘zhang‘),(6,‘lisi‘),(7,‘wangwu‘),(8,‘hello‘),(9,‘huhu‘);

 

GRANT SELECT ONmem.* to memcache@‘%‘ IDENTIFIED BY ‘123456‘;

FLUSH PRIVILEGES;

创建PHP测试页面:

# cat/website/data/memcache.php

<?php

$memcachehost =‘127.0.0.1‘;

$memcacheport =11211;

$memcachelife =60;

$memcache = newMemcache;

$memcache->connect($memcachehost,$memcacheport)or die ("Could not connect");

$query="select* from mem limit 10";

$key=md5($query);

if(!$memcache->get($key))

{

               $conn=mysql_connect("127.0.0.1","memcache","12345");

                mysql_select_db(memcache_test);

                $result=mysql_query($query);

                while($row=mysql_fetch_assoc($result))

                {

                        $arr[]=$row;

                }

                $f = ‘mysql‘;

                $memcache->add($key,serialize($arr),0,30);

                $data = $arr ;

}

else{

        $f = ‘memcache‘;

        $data_mem=$memcache->get($key);

        $data = unserialize($data_mem);

}

echo $f;

echo"<br>";

echo"$key";

echo"<br>";

//print_r($data);

foreach($data as$a)

{

                echo "number is<b><font color=#FF0000>$a[id]</font></b>";

                echo "<br>";

                echo "name is<b><font color=#FF0000>$a[name]</font></b>";

                echo "<br>";

 

}

?>

[root@localhostdata]#
