Nginx+Apache搭建前后端web生产环境

搭建前后端web生产环境
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?我提出我的看法.

php(fastcgi)不够稳定,经常出现502错误,生成相对复杂的页面没有优势,反而会使php-cgi进程变为僵尸进程.
安全性,多用户多站点权限问题.php(fastcgi)在应对多用户多站点往往捉襟见肘,不易于实施.
整合其他开发语言,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.

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

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

2.编译php,这里我们为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.补丁介绍信息请点击: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/

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 = 7200
eaccelerator.shm_prune_period = 7200
eaccelerator.shm_only = 1
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
ln -s /usr/local/lib/libevent-1.4.so.2 /usr/lib

cd /usr/local/src
tar -xzf memcached-1.4.4.tar.gz
cd memcached-1.4.4
./configure --with-libevent=/usr
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"
}

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"
do_stop
sleep 1
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 u+x /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

cd /usr/local/nginx/conf/
mv nginx.conf nginx.conf.bak
mkdir vhosts
vi nginx.conf

输入以下内容:

worker_processes 1;
worker_rlimit_nofile 65535;
events {
worker_connections 65535;
use epoll;
}
error_log /usr/local/nginx/logs/error.log info;
http {
include    mime.types;
default_type application/octet-stream;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 10;
gzip on;
gzip_http_version 1.0;
gzip_min_length 1100;
gzip_comp_level 3;
gzip_buffers 4 32k;
gzip_types    text/plain text/xml text/css application/x-javascript application/xml application/xml+rss text/javascript application/atom+xml;

server_name _;
access_log off;
location ~* \.(ftpquota|htaccess|asp|aspx|jsp|asa|mdb)$ {
deny all;
}
location / {
client_max_body_size    100m;
client_body_buffer_size 128k;
proxy_send_timeout   300;
proxy_read_timeout   300;
proxy_buffer_size    4k;
proxy_buffers     16 32k;

proxy_set_header   X-Real-IP $remote_addr;
proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
}
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 u+x 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

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

cd /usr/local/nginx/conf/vhosts
touch admin.com.conf
vi admin.com.conf
输入以下内容:

server {
error_log /usr/local/nginx/logs/admin.com-error_log warn;
listen 127.0.0.1:80;
server_name admin.com www.admin.com;
access_log off;
location ~* \.(gif|jpg|jpeg|png|ico|wmv|avi|asf|asx|mpg|mpeg \
|mp4|pls|mp3|mid|wav|swf|flv|html|htm|txt|js|css|exe|zip|rar \
|gz|tgz|bz2|uha|7z|doc|docx|xls|xlsx|pdf|iso)$ {
access_log /usr/local/apache/domlogs/admin.com combined;
root /home/admin/public_html;
expires 7d;
try_files $uri @backend;
}
error_page 400 401 402 403 404 405 406 407 408 409 500 501 502 503 504 @backend;
location @backend {
internal;
client_max_body_size    100m;
client_body_buffer_size 128k;
proxy_send_timeout   300;
proxy_read_timeout   300;
proxy_buffer_size    4k;
proxy_buffers     16 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
proxy_connect_timeout 30s;
proxy_redirect http://admin.com:81 http://admin.com;
proxy_redirect http://www.admin.com:81 http://www.admin.com;
proxy_pass http://127.0.0.1:81;
proxy_set_header   Host   $host;
proxy_set_header   X-Real-IP $remote_addr;
proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
}
location ~* \.(ftpquota|htaccess|asp|aspx|jsp|asa|mdb)$ {
deny all;
}
location / {
client_max_body_size    100m;
client_body_buffer_size 128k;
proxy_send_timeout   300;
proxy_read_timeout   300;
proxy_buffer_size    4k;
proxy_buffers     16 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
proxy_connect_timeout 30s;
proxy_redirect http://admin.com:81 http://admin.com;
proxy_redirect http://www.admin.com:81 http://www.admin.com;
proxy_pass http://127.0.0.1:81/;
proxy_set_header   Host   $host;
proxy_set_header   X-Real-IP $remote_addr;
proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
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 [email protected]
UseCanonicalName Off
CustomLog /usr/local/apache/domlogs/admin.com combined
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.

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%2FphpMyAdmin%2F3.3.0%2FphpMyAdmin-3.3.0-all-languages.tar.bz2/download
tar -jxf phpMyAdmin-3.3.0-all-languages.tar.bz2
mv phpMyAdmin-3.3.0-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 u+x vhosts
./vhosts
