有几个问题,
1、图中mysql用到了innodb和myisam,为什么这么设计?(后者读操作快,前者均衡)
3、为什么图中前端中nginx,后端用apache,为什么不用一个呢?(nginx用的最多的复杂均衡和url重写,下面有优缺点)
负载均衡是一个大型网站发展必须解决的问题,目前公司的网站就面临这样的问题。在国内, 已经有 新浪博客、新浪播客、网易新闻、六间房、56.com、Discuz!、水木社区、豆瓣、YUPOO、海内、迅雷在线 等多家网站使用 Nginx 作为Web服务器或反向代理服务器。下面两张图介绍了实现的大概思路,分为硬实现和软实现。
方法一、NetScaler负载均衡交换机动静分离系统架构图(硬实现)
方法二、Nginx反向代理负载均衡器动静分离系统架构图(软实现)
搭建前后端web生产环境:前段nginx+后端apache
前言: 谈到Linux下的web生产环境,大家就会想到apache这个开源服务器软件.apache可以整合大多数应用,比如 jsp,php,cgi,python等等,但是apache过于臃肿以及对静态文件响应过于缓慢让很多使用者感到头疼.而nginx作为新崛起的服务器 软件,在很多方面超出apache,定位也很明确:高性能的 HTTP 和反向代理服务器.因而,本篇主要讲的是nginx作为前端,apache作为后端的应用环境搭建过程.为什么不使用nginx+php(fastcgi)作为生产环境?
- php(fastcgi)不够稳定,容易出现50x错误,在生成相对复杂的页面时没有优势,长时间占用也会使php-cgi进程死去.
- 在安全性,多用户多站点的权限问题比较严重.php(fastcgi)在应对多用户多站点往往捉襟见肘,不易于实施.
- 整合其他语言,apache表现得游刃有余.资源利用恰到好处.
为 什么采用nginx做前端,apache作为后端的方案?nginx在处理静态内容上较apache是几倍或几十倍的差异,因而放在前面过滤静态内容是最 为恰当的.同时nginx也是一个负载均衡器,低资源消耗,高性能转发是它的特点.经过nginx在前面的过滤,后端的apache需要处理的内容相对就 比较少了.只需负责处理动态内容就可以了.在性能与稳定性的权衡下,使用nginx+apache搭配会让它们在各自擅长的领域展现自身的价值.
本教程以CentOS 5.4 32bit为环境.其他Linux发行版本暂未测试.nginx,php,apache,mysql,pureftpd均为最新稳定版.

mv ioncube_loader_lin_5.2.so /usr/local/ioncube/cd /usr/local/src
tar -zxf ZendOptimizer-3.3.9-linux-glibc23-i386.tar.gz
mkdir -p /usr/local/Zend/lib/Optimizer-3.3.9/php-5.2.x
cp ZendOptimizer-3.3.9-linux-glibc23-i386/data/5_2_x_comp/ZendOptimizer.so /usr/local/Zend/lib/Optimizer-3.3.9/php-5.2.x/ZendOptimizer.so
3.1.修改php.ini.
查找/etc/php.ini中的extension_dir = "./".将其修改为extension_dir = "/usr/local/lib/php/extensions/no-debug-non-zts-20060613/"
查找;include_path = ".:/php/includes",删除前面的分号,并修改为include_path = ".:/usr/lib/php:/usr/local/lib/php"
跳到最后一行,然后添加以下内容:
extension = "memcache.so"
extension = "pdo.so"
extension = "pdo_mysql.so"
extension = "pdo_sqlite.so"
extension = "sqlite.so"
extension = "eaccelerator.so"
eaccelerator.shm_size = 32
eaccelerator.cache_dir = "/tmp/eaccelerator"

zend_extension = "/usr/local/Zend/lib/Optimizer-3.3.9/php-5.2.x/ZendOptimizer.so"
4,安装Memcached(可选)
cd /usr/local/src
tar -xzf libevent-1.4.13-stable.tar.gz
cd libevent-1.4.13-stable
./configure
make
make install
echo "/usr/local/lib/" > /etc/ld.so.conf.d/libevent.conf
ldconfig -vcd /usr/local/src
tar -xzf memcached-1.4.4.tar.gz
cd memcached-1.4.4
./configure
make
make install
基本使用方法:
启动:/usr/local/bin/memcached -d -m 64 -p 11211 -u nobody -l localhost
关闭:killall -9 memcached
四.安装nginx
1.安装pcre库
cd /usr/local/src
tar -zxf pcre-8.01.tar.gz
cd pcre-8.01
./configure
make
make install
2.安装nginx
cd /usr/local/src
tar -zxf nginx-0.7.65.tar.gz
cd nginx-0.7.65
./configure --user=nobody --group=nobody --prefix=/usr/local/nginx --pid-path=/usr/local/nginx/logs/nginx.pid --error-log-path=/usr/local/nginx/logs/error.log --http-log-path=/usr/local/nginx/logs/access.log --http-client-body-temp-path=/tmp/nginx_client --http-proxy-temp-path=/tmp/nginx_proxy --http-fastcgi-temp-path=/tmp/nginx_fastcgi --with-http_stub_status_module
make
make install
2.1.添加init控制脚本
#! /bin/sh ulimit -n 65535 # Description: Startup script for nginx # chkconfig: 2345 55 25 PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin DESC="nginx daemon" NAME=nginx DAEMON=/usr/local/nginx/sbin/$NAME CONFIGFILE=/usr/local/nginx/conf/nginx.conf PIDFILE=/usr/local/nginx/logs/$NAME.pid SCRIPTNAME=/etc/init.d/$NAME set -e [ -x "$DAEMON" ] || exit 0 do_start() { $DAEMON -c $CONFIGFILE || echo -n "nginx already running" } do_stop() { kill -INT `cat $PIDFILE` || echo -n "nginx not running" } waitforexit() { count=${2:-30} while [ 0$count -gt 0 ] do PIDS=`ps -C$NAME --no-heading e | grep $DAEMON` || break PIDS=`echo "$PIDS" | awk '{print $1}' | tr '\n' ' '` echo Remaining processes: $PIDS do_stop sleep 2 count=`expr $count - 1` done if [ 0$count -eq 0 ]; then echo Remaining processes: $PIDS return 1 fi return 0 } do_reload() { kill -HUP `cat $PIDFILE` || echo -n "nginx can't reload" } case "$1" in start) echo -n "Starting $DESC: $NAME" do_start echo "." /etc/init.d/httpd start ;; stop) echo -n "Stopping $DESC: $NAME" do_stop echo "." /etc/init.d/httpd stop ;; reload) echo -n "Reloading $DESC configuration..." do_reload echo "." /etc/init.d/httpd restart ;; restart) echo -n "Restarting $DESC: $NAME" waitforexit "nginx" 20 do_start echo "." /etc/init.d/httpd restart ;; *) echo "Usage: $SCRIPTNAME {start|stop|reload|restart}" >&2 exit 3 ;; esac exit 0
保存退出,给该文件赋予执行权限并设置开机启动
chmod 755 /etc/init.d/nginx
chkconfig --level 345 nginx on
2.2.修改nginx配置文件,位于:/usr/local/nginx/conf/目录
mkdir -p /var/cache/nginx/cached
chmod 600 /var/cache/nginx/cached
cd /usr/local/nginx/conf/
mv nginx.conf nginx.conf.bak
mkdir vhosts
vi nginx.conf
输入以下内容:
worker_processes 2; worker_rlimit_nofile 20480; events { worker_connections 20480; use epoll; } error_log /usr/local/nginx/logs/error.log info; http { server_name_in_redirect off; server_names_hash_max_size 2048; server_names_hash_bucket_size 256; include mime.types; default_type application/octet-stream; sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 60; gzip on; gzip_http_version 1.0; gzip_min_length 1100; gzip_comp_level 3; gzip_buffers 4 32k; # gzip_types text/plain application/x-javascript text/xml text/css; gzip_types text/plain text/xml text/css application/x-javascript application/xml application/xml+rss text/javascript application/atom+xml; ignore_invalid_headers on; client_header_timeout 300; client_body_timeout 300; send_timeout 30; reset_timedout_connection on; connection_pool_size 256; client_header_buffer_size 256k; large_client_header_buffers 4 256k; request_pool_size 32k; output_buffers 4 32k; postpone_output 1460; proxy_cache_path /var/cache/nginx/cached levels=2:2 keys_zone=global:100m inactive=60m max_size=500m; proxy_temp_path /tmp/nginx_proxy; include "/usr/local/nginx/conf/vhosts/*.conf"; }
保存退出.
五.为apache安装rpaf模块,该模块用于apache做后端时获取访客真实的IP.
1.使用apxs安装模块.这里要使用此前apache编译安装后的apxs
cd /usr/local/src/
tar -zxf mod_rpaf-0.6.tar.gz
cd mod_rpaf-0.6
/usr/local/apache/bin/apxs -i -c -n mod_rpaf-2.0.so mod_rpaf-2.0.c
2.编辑/usr/local/apache/conf/httpd.conf,添加模块参数,查找LoadModule php5_module modules/libphp5.so,在下方添加:
LoadModule rpaf_module modules/mod_rpaf-2.0.so
#Mod_rpaf settings
RPAFenable On
RPAFproxy_ips 127.0.0.1 [your_ips]
RPAFsethostname On
RPAFheader X-Forwarded-For
上面出现的[your_ips]请修改为你本机所监听web服务的ip.多个IP用空格空开.
六.安装ftp服务器:pure-ftpd
1.编译安装
cd /usr/local/src/
tar -zxf pure-ftpd-1.0.28.tar.gz
cd pure-ftpd-1.0.28
./configure --prefix=/usr/local/pureftpd --with-language=simplified-chinese --with-everything
make
make install
chmod 755 configuration-file/pure-config.pl
cp configuration-file/pure-config.pl /usr/local/pureftpd/sbin/
mkdir /usr/local/pureftpd/etc/
cp configuration-file/pure-ftpd.conf /usr/local/pureftpd/etc/
ln -s /usr/local/pureftpd/bin/pure-pw /usr/local/bin/
2.配置pure-ftpd,这里采用PureDB的验证方式.
vi /usr/local/pureftpd/etc/pure-ftpd.conf
查找 PureDB /etc/pureftpd.pdb 取消前面的#号并设置成PureDB/usr/local/pureftpd/etc/pureftpd.pdb
查找 PassivePortRange 取消前面的#号
其他参数根据需要进行修改
3.添加自启动.这里不创建init脚本.直接放在/etc/rc.local启动即可
echo "/usr/local/pureftpd/sbin/pure-config.pl /usr/local/pureftpd/etc/pure-ftpd.conf --daemonize" >> /etc/rc.local
至此.所有安装工作结束.
如何使用这套系统
一,做好必要的安全工作
设置用户家目录/home/user,相关配置参数文件,以及访问日志等目录的权限.
chmod 711 /home
chmod 711 /usr/local/pureftpd/etc
chmod 711 /usr/local/apache/conf/vhosts
chmod 711 /usr/local/nginx/conf/vhosts
chmod 711 /usr/local/apache/domlogs
chmod 711 /usr/local/apache/logs
chmod 600 /var/cache/nginx/cached
二,如何创建用户
创建用户分两个步骤.第一步创建系统用户.该命令直接创建用户家目录.第二步创建ftp用户.创建该用户依赖系统用户的创建.步骤如下(以创建用户名为admin为例):
useradd admin -m -s /sbin/nologin
pure-pw useradd admin -u admin -g admin -d /home/admin -m[第一次执行不可用]
pure-pw mkdb[仅限第一次执行]
注意.通过上述方法安装的ftp服务器在第一次创建用户的时候不可以在pure-pw useradd ...后直接添加参数-m更新ftp用户数据库.需要分两步执行.以后可以直接在创建用户时在后面添加参数-m,执行之后会提示让你输入密码.需要重复输入两次.
三.如何绑定域名
由于采用前后端操作.因此需要修改两个服务器软件的虚拟主机参数.实例如下(以admin.com为例,用户目录承接上文的/home/admin):
1.创建nginx虚拟主机参数
首先先把公共cache参数和proxy参数写进文件中
cd /usr/local/nginx/conf
touch cache.inc proxy.inc
然后分别编辑者两个文件。
vi cache.inc
proxy_cache global;
proxy_cache_key $host$uri$is_args$args;
#proxy_cache_valid 200 302 10m;
#proxy_cache_valid 301 1h;
#proxy_cache_valid any 1m;
proxy_cache_use_stale error timeout http_500 http_502 http_503 http_504;
proxy_temp_file_write_size 64k;
proxy_max_temp_file_size 56m;
vi proxy.inc
proxy_connect_timeout 30s;
proxy_send_timeout 300;
proxy_read_timeout 300;
proxy_buffer_size 64k;
proxy_buffers 16 32k;
proxy_busy_buffers_size 64k;
#proxy_pass http://127.0.0.1:81;
proxy_redirect off;
proxy_hide_header Vary;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
然后再编辑虚拟主机文件就会很清晰了
cd /usr/local/nginx/conf/vhosts
touch admin.com.conf
vi admin.com.conf
输入以下内容:
server { error_log /var/log/nginx/vhost-error_log warn; listen 127.0.0.1:80; server_name admin.com www.admin.com; access_log /usr/local/apache/domlogs/admin.com combined; location / { root /home/admin/public_html; proxy_cache_valid 200 301 302 10m; proxy_cache_valid any 1m; expires 1d; proxy_pass http://127.0.0.1:81; include proxy.inc; include cache.inc; } location ~ .*\.(jpg|jpeg|png|gif|bmp|ico|js|css|mp3|wav|swf|mov|doc|pdf|xls|ppt|docx|pptx|xlsx)$ { proxy_cache_valid 200 10s; expires 7d; proxy_pass http://127.0.0.1:81; include proxy.inc; include cache.inc; } location ~ .*\.(php|jsp|cgi)?$ { proxy_pass http://127.0.0.1:81; include proxy.inc; } location ~ /\.ht { deny all; } }
保存退出,注意将上述出现的127.0.0.1替换本机监听web服务的IP
2.创建apache虚拟主机配置文件
cd /usr/local/apache/conf/vhosts
touch admin.com.conf
vi admin.com.conf
输入以下内容:
<VirtualHost 127.0.0.1:81> ServerName admin.com ServerAlias www.admin.com DocumentRoot /home/admin/public_html ServerAdmin admin@evlit.com UseCanonicalName Off php_admin_value open_basedir "/home/admin:/usr/lib/php:/usr/local/lib/php:/tmp" <IfModule !mod_disable_suexec.c> SuexecUserGroup admin admin </IfModule> ScriptAlias /cgi-bin/ /home/admin/public_html/cgi-bin/ </VirtualHost>
保存退出,注意将上述出现的127.0.0.1替换本机监听web服务的IP,用户名admin改为虚拟主机用户的名称.
四.如何管理MySQL数据库
1.下载最新版PhpMyAdmin源码包
mkdir -p /var/www/html
chmod -R 711 /var/www
cd /var/www/html
wget http://sourceforge.net/projects/phpmyadmin/files/phpMyAdmin/3.3.3/phpMyAdmin-3.3.3-all-languages.zip/download
unzip phpMyAdmin-3.3.3-all-languages.zip
mv phpMyAdmin-3.3.3-all-languages phpmyadmin
2.增加apache配置,编辑httpd.conf,转到最后一行
cd /usr/local/apache/conf
vi httpd.conf /* shift+g转到最后一行 */
#Managed Tools
<VirtualHost 127.0.0.1:81 *>
ServerName localhost
ServerAlias pma.*
DocumentRoot /var/www/html/phpmyadmin
ServerAdmin admin@localhost
UseCanonicalName Off
</VirtualHost>
同样,修改上述出现的127.0.0.1为你提供web服务的IP.重启apache后.我们打开绑定到服务器IP的pma.yourdomain.com即可访问到phpmyadmin.第一次使用.需要进行配置.具体配置请善用Google.
其他没有照顾到的地方自行添加即可.如perl,sendmail等.
为方便管理员添加用户及绑定域名.我编写了一个脚本.
wget http://icodex.org/vhosts
chmod 755 vhosts
./vhosts
