针对中小型网站(3000人左右/15分钟)的服务器架构
针对中小型网站(3000人左右/15分钟)的服务器架构
本文系原创, 转载注明来自: www.hao32.com
本文涉及的服务器构架主要针对3000人左右/15分钟的中小型网站, 多见于discuz!论坛构建的社区等等
环境为linux(内核2.6+), nginx, php(fastcgi), mysql 等高效开源软件构成, 成本低廉, 是普通个人站长朋友的首选,
但是针对部分企业, 这个方案也是一个非常不错的选择!
至于nginx和apache等web服务器的性能比较这里就不多说了
本文是以实例的方式来描述安装以及配置等情况, 供各位参考
1. 硬件环境
一台web服务器, 一台db服务器, 没有raid
web服务器 至强双核1.60GHz, 2G, 73GSCSI*2
db服务器至强双核1.60GHz, 2G, 73GSCSI*2
2. 系统环境
CentOS 5.x (内核2.6+)
简单的说下前期工作:安装系统尽可能的精简, 检查系统时间, dmesg看看有无错误, 关闭selinux,ipv6, 升级系统到最新yum -y update
安装如下web环境必要的软件包:
# yum install -y ntp vim-enhanced gcc gcc-c++ gcc-g77 flex bison autoconf automake bzip2-devel ncurses-devel libjpeg-devel libpng-devel libtiff-devel freetype-devel pam-devel kernel
3. 准备软件
nginx-0.6.31.tar.gz
pcre-7.3.tar.gz
php-5.2.6.tar.bz2
eaccelerator-0.9.5.3.tar.bz2
ZendOptimizer-3.3.0-linux-glibc21-i386.tar.gz
lighttpd-1.4.19.tar.bz2
libxml2-2.6.30.tar.gz
libmcrypt-2.5.8.tar.bz2
gd-2.0.34.tar.gz
mysql-5.0.51a-linux-i686-glibc23.tar.gz
以上软件都是目前最新最稳定的版本, 查找和下载以上软件或者更新版本
请在www.google.com输入: 软件全名 intitle:index
一般头几个都是可以下载的, 找个最快的就可以了
<!---------------以下都是web服务器上的配置--------------->
4.开始安装环境:
(1)安装gd库
# tar zxvf gd-2.0.34.tar.gz
# cd gd-2.0.34
# ./configure --prefix=/usr/local/gd2
# make
# make install
(2)安装LibXML2
# tar zxvf libxml2-2.6.30.tar.gz
# cd libxml2-2.6.30
# ./configure --prefix=/usr/local/libxml2
# make
# make install
(3)安装LibMcrypt
# cd /usr/local/src
# tar jxvf libmcrypt-2.5.8.tar.bz2
# cd libmcrypt-2.5.8
# ./configure --prefix=/usr/local/libmcrypt
# make
# make install
(4)解压mysql-5.0.51a-linux-i686-glibc23.tar.gz, 然后把解开的包里的lib和include目录转移到任意目录, 例如/usr/local/mysql
因为编译php5需要用到mysql的支持(--with-mysql)
# tar zxvf mysql-5.0.51a-linux-i686-glibc23.tar.gz
# cd mysql-5.0.51a-linux-i686-glibc23
# mkdir -p /user/local/mysql
# mv ./lib ./include /user/local/mysql/
(5)编译php(fastcfi模式)
# ./configure --prefix=/usr/local/php-fcgi --enable-fastcgi --enable-discard-path --enable-force-cgi-redirect --with-config-file-path=/usr/local/php-fcgi/etc --enable-zend-multibyte --with-mysql=/usr/local/mysql --with-libxml-dir=/usr/local/libxml2 --with-gd=/usr/local/gd2 --with-jpeg-dir --with-png-dir --with-bz2 --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-mcrypt=/usr/local/libmcrypt --enable-sysvsem --enable-inline-optimization --enable-soap --enable-gd-native-ttf --enable-ftp --enable-mbstring --enable-exif --disable-debug --disable-ipv6
# make
# make install
# cp php.ini-dist /usr/local/php-fcgi/etc/php.ini
(6)安装ZendOptimizer
# tar zxvf ZendOptimizer-3.3.0-linux-glibc21-i386.tar.gz
# cd ZendOptimizer-3.3.0-linux-glibc21-i386
# ./install
基本上是一直回车, 值得注意一点的是:
当您看到要选择php的路径时就写:
/usr/local/php-fcgi/etc
看到Are you using Apache Web server?
这里要选NO
(7)安装eaccelerator
# tar jxvf eaccelerator-0.9.5.3.tar.bz2
# cd eaccelerator-0.9.5.3
# ./configure --enable-eaccelerator=shared --with-php-config=/usr/local/php-fcgi/bin/php-config
# make
# make install
# mkdir /tmp/eaccelerator && chmod 777 /tmp/eaccelerator && touch /var/log/eaccelerator_log
编辑php.ini
# vi /usr/local/php-fcgi/etc/php.ini
在最底部加上:
extension=/usr/local/php-fcgi/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so
eaccelerator.shm_size=\"16\"
eaccelerator.cache_dir=\"/tmp/eaccelerator\"
eaccelerator.enable=\"1\"
eaccelerator.optimizer=\"1\"
eaccelerator.check_mtime=\"1\"
eaccelerator.debug=\"0\"
eaccelerator.log_file = \"/var/log/eaccelerator_log\"
eaccelerator.filter=\"\"
eaccelerator.shm_max=\"0\"
eaccelerator.shm_ttl=\"0\"
eaccelerator.shm_prune_period=\"0\"
eaccelerator.shm_only=\"0\"
eaccelerator.compress=\"1\"
eaccelerator.compress_level=\"9\"
(8)安装nginx的rewrite模块需要pcre库
# tar zxvf pcre-7.3.tar.gz
# cd pcre-7.3
# ./configure
# make && make install
(9)安装nginx
# ./configure --prefix=/usr/local/nginx/ --with-http_stub_status_module
# make && make install
(10)编译出lighttpd中附带的spawn-fcgi,它的作用是来启动php-cgi
# tar jxvf lighttpd-1.4.19.tar.bz2
# cd lighttpd-1.4.19
# ./configure
# make
# cp src/spawn-fcgi /usr/local/php-fcgi/bin/
到现在为之, 安装过程已经结束
5.开始配置环境:
# cd /usr/local/nginx/conf
# mkdir vhosts
先备份即将要修改的文件
# cp nginx.conf nginx.conf.bak
# cp fastcgi_params fastcgi_params.bak
# mkdir -p /usr/local/nginx/temp/client_body
# mkdir /usr/local/nginx/var
(1)编辑nginx主配置文件nginx.conf
编辑nginx.conf, 并且把其内容修改为, 最后几行注意自定义一下
daemon on;
worker_processes 4;
worker_cpu_affinity 0001 0010 0100 1000;
error_log /dev/null;
pid var/nginx.pid;
lock_file var/nginx.lock;

log_format main '$remote_addr - $remote_user [$time_local] $request '
'\"$status\" $body_bytes_sent \"$http_referer\" '
'\"$http_user_agent\" \"$http_x_forwarded_for\"';
access_log /dev/null;
# 引用你即将要放置的虚拟主机配置文件
include vhosts/hao32.com;
include vhosts/linuxsense.org;
}
(2)编辑php在fastcgi模式下的配置文件:
# vi fastcgi_params
内容修改为:
fastcgi_paramQUERY_STRING $query_string;
fastcgi_paramREQUEST_METHOD $request_method;
fastcgi_paramCONTENT_TYPE $content_type;
fastcgi_paramCONTENT_LENGTH $content_length;
fastcgi_paramSCRIPT_NAME$fastcgi_script_name;
fastcgi_paramREQUEST_URI$request_uri;
fastcgi_paramDOCUMENT_URI $document_uri;
fastcgi_paramDOCUMENT_ROOT$document_root;
fastcgi_paramSERVER_PROTOCOL$server_protocol;
fastcgi_paramGATEWAY_INTERFACECGI/1.1;
fastcgi_paramSERVER_SOFTWAREnginx/$nginx_version;
fastcgi_paramREMOTE_ADDR$remote_addr;
fastcgi_paramREMOTE_PORT$remote_port;
fastcgi_paramSERVER_ADDR$server_addr;
fastcgi_paramSERVER_PORT$server_port;
fastcgi_paramSERVER_NAME$server_name;
# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_paramREDIRECT_STATUS200;
(2)编辑虚拟主机的配置文件
# cd vhosts/
# vi hao32.com
添加内容如下
server {
listen 80;
server_namehao32.com www.hao32.com;
# 可以选择打开日志
#access_log/var/log/hao32.com/access.log combined buffer=32k;
#error_log /var/log/hao32.com/error.log warn;
location / {
index index.html index.htm index.php;
root/www/wwwroot/hao32.com;
location ~ \\.php$ {
include fastcgi_params;
fastcgi_index index.php;
fastcgi_pass127.0.0.1:8407;
fastcgi_param SCRIPT_FILENAME /www/wwwroot/hao32.com$fastcgi_script_name;
}
location /hao32-status {
stub_status on;
access_logoff;
}
}
# vi linuxsense.org
添加内容如下, 这是一个带有discuz!默认rewrite规则的主机事例
server {
listen 80;
server_namelinuxsense.org www.linuxsense.org;
# 可以选择打开日志
#access_log/var/log/linuxsense.org/access.log combined buffer=32k;
#error_log /var/log/linuxsense.org/error.log warn;
location / {
index index.html index.htm index.php;
root/www/wwwroot/linuxsense.org;
rewrite ^(.*)/archiver/((fid|tid)-[\\w\\-]+\\.html)$ $1/archiver/index.php?$2 last;
rewrite ^(.*)/forum-([0-9]+)-([0-9]+)\\.html$ $1/forumdisplay.php?fid=$2&page=$3 last;
rewrite ^(.*)/thread-([0-9]+)-([0-9]+)-([0-9]+)\\.html$ $1/viewthread.php?tid=$2&extra=page\\%3D$4&page=$3 last;
rewrite ^(.*)/profile-(username|uid)-(.+)\\.html$ $1/viewpro.php?$2=$3 last;
rewrite ^(.*)/space-(username|uid)-(.+)\\.html$ $1/space.php?$2=$3 last;
rewrite ^(.*)/tag-(.+)\\.html$ $1/tag.php?name=$2 last;
location ~ \\.php$ {
include fastcgi_params;
fastcgi_index index.php;
fastcgi_pass127.0.0.1:8408;
fastcgi_param SCRIPT_FILENAME /www/wwwroot/linuxsense.org$fastcgi_script_name;
}
location /linuxsense-status {
stub_status on;
access_logoff;
}
}
(3)增加网站用户
useradd hao32 -d /www/wwwroot/hao32.com -s /sbin/nologin
useradd linuxsense -d /www/wwwroot/linuxsense.org -s /sbin/nologin
如果参数-d后的路径本身就存在, 会提示
useradd: warning: the home directory already exists.
Not copying any file from skel directory into it.
这并不影响,
chown -R hao32:hao32 /www/wwwroot/hao32.com
chown -R linuxsense:linuxsense /www/wwwroot/linuxsense
(5)创建一个要等会要使用的用户列表USER_LIST
# vi /usr/local/nginx/conf/vhosts/USER_LIST
格式如下
去掉-a -p -C -u -f等参数, 分表是本机php要使用的ip地址, 端口, 用户
注意, 如果有两个用户就要两行, 主要不要有空白行
-a 127.0.0.1 -p 8407 -C 20 -u hao32 -f
-a 127.0.0.1 -p 8408 -C 200 -u linuxsense -f
(6)制作php-cgi,nginx等启动脚本, 并加入系统服务
# vi /etc/init.d/php-cgi
# chmod 755 /etc/init.d/php-cgi
编辑php-cgi启动脚本, 加入以下代码:
#!/bin/bash
#
# PHP-FastCGI Control Script for Red Hat based Linux.
# Written by hao32
# chkconfig: 3 89 89
# description: PHP Fast-CGI
# PHP Users Settings

RETVAL=0
prog=\"PHP FastCGI\"
mkdir -p /var/run/php-fcgi 2> /dev/null
start() {
echo -n $\"Starting $prog: \"
cat $USER_INFO | while read list
do
daemon $PHP_SPAWN $list $PHP_SBIN
done
RETVAL=$?
if [ $RETVAL -eq 0 ]
then
touch /var/lock/subsys/php-fcgi
fi
echo
return $RETVAL
}
stop() {
echo -n $\"Stopping $prog: \"
killproc php-cgi
RETVAL=$?
if [ $RETVAL -eq 0 ]
then
rm -f /var/lock/subsys/php-fcgi
fi
echo
return $RETVAL
}
restart() {
stop
echo -ne \"Restart...\\n\"
sleep 3
start
}
case \"$1\" in
start)
start
;;
stop)
stop
;;
restart)
restart
;;
*)
echo $\"Usage: $0 {start|stop|restart}\"
RETVAL=1
esac
exit $RETVAL
# vi /etc/init.d/nginx
# chmod 755 /etc/init.d/nginx
编辑nginx启动脚本, 加入以下代码
#!/bin/bash
#
# Nginx Control Script for Red Hat based Linux.
# chkconfig: 3 90 90
# description: Nginx Web Server Control
# Source Function Library
. /etc/init.d/functions
# Nginx Settings
NGINX_SBIN=\"/usr/local/nginx/sbin/nginx\"
NGINX_CONF=\"/usr/local/nginx/conf/nginx.conf\"
NGINX_PID=\"/usr/local/nginx/var/nginx.pid\"
RETVAL=0
prog=\"nginx\"
mkdir -p /var/run/nginx 2> /dev/null
start() {
echo -n $\"Starting $prog: \"
daemon $NGINX_SBIN -c $NGINX_CONF
RETVAL=$?
if [ $RETVAL -eq 0 ]
then
touch /var/lock/subsys/nginx
fi
echo
return $RETVAL
}
stop() {
echo -n $\"Stopping $prog: \"
killproc -p $NGINX_PID $NGINX_SBIN -TERM
RETVAL=$?
if [ $RETVAL -eq 0 ]
then
rm -f /var/lock/subsys/nginx
fi
echo
return $RETVAL
}
reload() {
echo -n $\"Reloading $prog: \"
killproc -p $NGINX_PID $NGINX_SBIN -HUP
RETVAL=$?
echo
return $RETVAL
}
restart() {
stop
start
}
configtest() {
$NGINX_SBIN -c $NGINX_CONF -t
exit
}
case \"$1\" in
start)
start
;;
stop)
stop
;;
reload)
reload
;;
restart)
restart
;;
configtest)
configtest
;;
*)
echo $\"Usage: $0 {start|stop|reload|restart|configtest}\"
RETVAL=1
esac
exit $RETVAL
增加到系统服务器
chkconfig --add nginx
chkconfig --add php-cgi
现在可以启动php-cgi和nginx了
service nginx start
service php-cgi start
重启动使用restart
<!---------------以上都是web服务器上的配置--------------->
<!---------------以下都是db服务器上的配置--------------->
开始安装配置mysql
# tar zxvf mysql-5.0.51a-linux-i686-glibc23.tar.gz
# mv mysql-5.0.51a-linux-i686-glibc23 /usr/local/

输入一下内(可以复制粘贴啊), 增加一个可以远程连接的用户, 本例用户是hao32, 密码是:hao32.com
然后在web服务器上使用诸如phpmyadmin等软件连接上本台db服务器, 删增相应的用户
