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 6.0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.

获取操作系统源更新.

yum update
yum -y install gcc gcc-c++ bison patch unzip mlocate flex wget automake autoconf gd cpp gettext readline-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel libidn libidn-devel openldap openldap-devel openldap-clients openldap-servers nss_ldap expat-devel libtool libtool-ltdl-devel

如果系统默认安装了apache,请先卸载.执行:

yum remove httpd

一.安装Mysql.安装最新稳定版5.1.45版本,并没有采用最新开发版.

groupadd mysql -g 27
useradd mysql -u 27 -g 27 -c "MySQL Server" -d /var/lib/mysql -m
cd /usr/local/src
tar -zxf mysql-5.1.45.tar.gz
cd mysql-5.1.45
./configure --prefix=/usr/local/mysql --localstatedir=/var/lib/mysql --with-unix-socket-path=/var/lib/mysql/mysql.sock --with-mysqld-user=mysql --enable-assembler --enable-thread-safe-client --with-extra-charsets=all --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-plugins=partition,innodb_plugin,myisam,myisammrg
make && make install
cd ../

cp /usr/local/mysql/share/mysql/my-medium.cnf /etc/my.cnf
/usr/local/mysql/bin/mysql_install_db --user=mysql
chown -R mysql.mysql /var/lib/mysql
chgrp -R mysql /usr/local/mysql/.
cp /usr/local/mysql/share/mysql/mysql.server /etc/init.d/mysql
chmod u+x /etc/init.d/mysql
chkconfig --level 345 mysql on
echo "/usr/local/mysql/lib/mysql" >> /etc/ld.so.conf
echo "/usr/local/lib" >>/etc/ld.so.conf
ldconfig
ln -s /usr/local/mysql/lib/mysql /usr/lib/mysql
ln -s /usr/local/mysql/include/mysql /usr/include/mysql
ln -s /usr/local/mysql/bin/mysql_config /usr/bin/mysql_config
service mysql start
/usr/local/mysql/bin/mysqladmin -u root password root
service mysql restart
service mysql stop

二.编译安装apache(httpd).apache的执行用户为nobody.

cd /usr/local/src
tar -zxf httpd-2.2.15.tar.gz
cd httpd-2.2.15
./configure --prefix=/usr/local/apache --enable-headers --enable-mime-magic --enable-proxy --enable-rewrite --enable-ssl --enable-suexec --disable-userdir --with-included-apr --with-mpm=prefork --with-ssl=/usr --with-suexec-caller=nobody --with-suexec-docroot=/ --with-suexec-gidmin=100 --with-suexec-logfile=/usr/local/apache/logs/suexec_log --with-suexec-uidmin=100 --with-suexec-userdir=public_html
make
make install
mkdir /usr/local/apache/domlogs
cp /usr/local/apache/bin/apachectl /etc/init.d/httpd

1.编辑/etc/init.d/httpd,在首行#!/bin/sh下添加:

# Startup script for the Apache Web Server
#
# chkconfig: - 85 15
# description: Apache is a World Wide Web server. It is used to serve \
# HTML files and CGI.
# processname: httpd
# pidfile: /usr/local/apache/logs/httpd.pid

ulimit -n 1024
ulimit -n 4096
ulimit -n 8192
ulimit -n 16384
ulimit -n 32768

保存退出.

2.配置apache配置参数文件httpd.conf,位于/usr/local/apache/conf/目录

cd /usr/local/apache/conf/
mv httpd.conf httpd.conf.bak
mkdir vhosts
vi httpd.conf

上述虚拟主机配置中出现的127.0.0.1请改为你本机公网IP.

三.编译安装php(mod_php)

1.编译安装相关支持库

cd /usr/local/src
tar -zxf libiconv-1.13.1.tar.gz
cd libiconv-1.13.1/
./configure
make
make install

cd /usr/local/src
tar -jxf libmcrypt-2.5.8.tar.bz2

cd /usr/local/src
tar -zxf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
/sbin/ldconfig
./configure
make
make install

2.编译php,这里为php打入补丁.有助于防止邮件发送被滥用(多用户)以及在邮件中提供有价值的信息.补丁介绍信息请访问:http://www.lancs.ac.uk/~steveb/patches/php-mail-header-patch/

cd /usr/local/src
tar -zxf php-5.2.13.tar.gz
patch -d php-5.2.13 -p1 < php5-mail-header.patch
cd php-5.2.13
./configure --prefix=/usr/local --with-config-file-path=/etc --with-apxs2=/usr/local/apache/bin/apxs --enable-bcmath --enable-calendar --enable-exif --enable-ftp --enable-gd-native-ttf --enable-libxml --enable-magic-quotes --enable-mbstring --enable-pdo=shared --enable-soap --enable-sockets --enable-zip --with-bz2 --with-curl --with-curlwrappers --with-freetype-dir --with-gd --with-gettext --with-jpeg-dir --with-kerberos --with-libexpat-dir=/usr --with-libxml-dir=/usr --with-mcrypt=/usr --with-mhash=/usr --with-mysql=/usr --with-mysql-sock=/var/lib/mysql/mysql.sock --with-mysqli=/usr/bin/mysql_config --with-openssl=/usr --with-openssl-dir=/usr --with-pdo-mysql=shared --with-pdo-sqlite=shared --with-png-dir=/usr --with-sqlite=shared --with-ttf --with-xmlrpc --with-zlib -with-zlib-dir=/usr
make ZEND_EXTRA_LIBS='-liconv'
make install
cp php.ini-dist /etc/php.ini

3.安装php扩展模块

cd /usr/local/src
tar -zxf memcache-2.2.5.tgz
cd memcache-2.2.5/
phpize
./configure --with-php-config=/usr/local/bin/php-config --with-zlib-dir --enable-memcache
make
make install

cd /usr/local/src
tar -jxf eaccelerator-0.9.6.tar.bz2
cd eaccelerator-0.9.6/
phpize
./configure --enable-eaccelerator=shared --with-php-config=/usr/local/bin/php-config
make
make install
mkdir -p /tmp/eaccelerator
chmod 777 /tmp/eaccelerator
echo "mkdir -p /tmp/eaccelerator" >> /etc/rc.local
echo "chmod 777 /tmp/eaccelerator" >> /etc/rc.local

cd /usr/local/src
tar -zxf ImageMagick.tar.gz
cd ImageMagick-*
./configure
make
make install

cd /usr/local/src
tar -zxf imagick-2.3.0.tgz
cd imagick-2.3.0/
phpize
./configure --with-php-config=/usr/local/bin/php-config
make
make install

cd /usr/local/src
tar -zxf suhosin-0.9.29.tgz
cd suhosin-0.9.29
phpize
./configure
make
make install

cd /usr/local/src
tar -zxf ioncube_loaders_lin_x86.tar.gz
cd ioncube
mkdir /usr/local/ioncube
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"
eaccelerator.enable = 1
eaccelerator.optimizer = 0
eaccelerator.debug = 0
eaccelerator.name_space = ""
eaccelerator.check_mtime = 1
eaccelerator.filter = ""
eaccelerator.shm_max = 0
eaccelerator.shm_ttl = 3600
eaccelerator.shm_prune_period = 3600
eaccelerator.shm_only = 0
eaccelerator.compress = 0
eaccelerator.compress_level = 9
eaccelerator.keys = shm
eaccelerator.sessions = shm
eaccelerator.content = shm

zend_extension = "/usr/local/ioncube/ioncube_loader_lin_5.2.so"
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 -v

cd /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
