前言：
本文基于step by step的结构向大家介绍Nginx构建高性能WEB的全过程.并且我们在
生产服务器上运行一个月非常稳定，所以整理出来供大家分享。希望能够帮助
更多的初学者轻松构建高性能的WEB服务器。对文中提到的相关操作有任何问题都可以
到LinuxTone论坛去交流提问，我们将第一时间为你解答，同时把网友的建议加入，及
时更新相关内容.
系统环境:
CentOS 5.1+nginx-0.6.31+php-5.2.6+memcache-2.2.3+xcache-1.2.2+mysql-5.0.51b
一、系统安装
1. 系统分区
/boot 100M左右
SWAP物理内存的2倍(如果你的物理内存大于4G以上，分配4G即可)
/ 分区15~20G
/usr/local 20G (用于安装软件)
/data 剩余所有空间
*具体分区请根据相关业务划分，具体安装本文不作介绍.
2.系统初始化脚本(根据具体需求关闭不需要的服务)
#vi init.sh
复制内容到剪贴板代码:
#welcome cat/etc/modprobe.conf
echo "alias ipv6 off" >> /etc/modprobe.conf
/sbin/chkconfig --level 35 ip6tables off
echo "ipv6 is disabled!"
#disable selinux
sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config
echo "selinux is disabled,you must reboot!"
#vim
sed -i "8 s/^/alias vi='vim'/" /root/.bashrc
echo 'syntax on' > /root/.vimrc
#LANG=en
sed -i -e 's/^LANG=.*/LANG="en"/' /etc/sysconfig/i18n
#tunoff services
#--------------------------------------------------------------+
cat/dev/null 2>&1
5) 下载编译相关的源码包.
#vi list 在list文件里填入以后下载地址列表.

wget -i list 下载 2. 编译安装软件包
源码编译安装所需包(Source)
1) 升级OpenSSL及OpenSSH
复制内容到剪贴板代码:
tar xvf openssl-0.9.8h.tar.gz cd openssl-0.9.8h
#vi in_openssl.sh
./config --prefix=/usr/local/openssl
make
make test
make install
# sh in_openssl.sh
#tar xvf openssh-5.0p1.tar.gz
#cd openssh-5.0p1
# vi in_openssh.sh
./configure\
"--prefix=/usr" \
"--with-pam" \
"--with-zlib" \
"--sysconfdir=/etc/ssh" \
"--with-ssl-dir=/usr/local/openssl" \
"--with-md5-passwords"
make
make install
# sh in_openssh.sh
禁用 SSH V1 协议:找到#Protocol 2,1改为：Protocol 2 禁用服务器端GSSAPI找到以下两行，并将它们注释：
GSSAPIAuthentication yes
GSSAPICleanupCredentials yes
禁用 DNS 名称解析
找到：#UseDNS yeas改为：UseDNS no
禁用客户端 GSSAPI
# vi /etc/ssh/ssh_config 找到：GSSAPIAuthentication yes 将这行注释掉。
最后，确认修改正确后重新启动 SSH 服务
# service sshd restart
# ssh -v 确认 OpenSSH 以及 OpenSSL 版本正确。
以上SSH配置可利用以下脚本自动修改:
#vi init_ssh.sh
复制内容到剪贴板代码:
#init_ssh.sh ssh_cf="/etc/ssh/sshd_config"
sed -i -e '74 s/^/#/' -i -e '76 s/^/#/' $ssh_cf
sed -i "s/#UseDNS yes/UseDNS no/" $ssh_cf
#client
sed -i -e '44 s/^/#/' -i -e '48 s/^/#/' $ssh_cf
echo "ssh is init is ok.............."
#sh init_ssh.sh # /etc/init.d/sshd restart
Stopping sshd:
Starting sshd:
# ssh -v
OpenSSH_5.0p1, OpenSSL 0.9.8h 28 May 2008

3)配置修改php-fpm脚本 配置php-fpm脚本:
cd /usr/local/php-fcgi/etc/
vi php-fpm.conf修改如下内容:(进入vi编辑器，输入:set nu 显示行号.)
41 127.0.0.1:8085

124 51200
4) Nginx+PHP(fastcgi)启动脚本参考:http://bbs.linuxtone.org/thread-372-1-2.html
四、Nginx多虚拟主机配置及基本优化(以配置Discuz!论坛为例)
1.配置Nginx虚拟主机(防盗链及expires设置)
#vi /usr/local/nginx/conf/vhosts/bbs.linuxtone.org.conf
复制内容到剪贴板代码:
server {
listen 80;
server_namebbs.linuxtone.org www.linuxtone.org;
index index.html index.php index.htm;
root/data/www/wwwroot/lt/bbs;
#access_log /var/log/nginx/access_bbs.redocn.com.logcombined;
location / {
if (!-e $request_filename) {
rewrite ^/archiver/((fid|tid)-[\w\-]+\.html)$ /archiver/index.php?$1 last;
rewrite ^/forum-(+)-(+)\.html$ /forumdisplay.php?fid=$1&page=$2 last;
rewrite^/thread-(+)-(+)-(+)\.html$/viewthread.php?tid=$1&extra=page%3D$3&page=$2
last;
rewrite ^/space-(username|uid)-(.+)\.html$ /space.php?$1=$2 last;
rewrite ^/tag-(.+)\.html$ /tag.php?name=$1 last;
break;
}
}
#Preventing hot linking of images and other file types
location ~* ^.+\.(gif|jpg|png|swf|flv|rar|zip)$ {
valid_referers none blocked server_names *.linuxtone.org http://localhost;
if ($invalid_referer) {
rewrite ^/ http://bbs.linuxtone.org/images/default/logo.gif;
return 403;
}
}
# Add expires header for static content
location ~* \.(js|css|jpg|jpeg|gif|png|swf)$ {
if (-f $request_filename) {
root /data/www/wwwroot/lt/bbs;
expires 1d;
break;
}
}
#support php
location ~ .*\.php?$
{
include enable_php5.conf;
}
}
2.Nginx搭建下载站点限制并发数和速率.复制内容到剪贴板代码:
vi /usr/local/nginx/conf/vhosts/down.redocn.com.conf limit_zone one$binary_remote_addr10m;
server
{
listen 80;
server_namedown.redocn.com;
index index.html index.htm index.php;
root /data/www/wwwroot/down;
error_page 404 /index.php;
# redirect server error pages to the static page /50x.html
error_page 500 502 503 504/50x.html;
location = /50x.html {
root html;
}
#Zone limit
location / {
limit_conn one1;
limit_rate20k;
}
# serve static files
location ~ ^/(images|javascript|js|css|flash|media|static)/{
root /data/www/wwwroot/down;
expires 30d;
}
}
3.如何实现Nginx身份验证 实现输入http://count.linuxtone.org/tongji 要求输入用户名和密码验证才可查看内内。配置方法如下：
创建统计配置文件:
复制内容到剪贴板代码:
mkdir /usr/local/nginx/conf/htpasswd#创建存放密码的目录 /usr/local/apache2/bin/htpasswd -c /usr/local/nginx/conf/htpasswd/tongji admin
server
{
listen 80;
server_namecount.linuxtone.org;
index index.html index.php;
root/data/www/wwwroot/count;
access_log /data/logs/access_count.linuxtone.org.logcombined;
#error page
error_page 404 http://www.linuxtone.org/error.html;
error_page 500 502 503 504 http://www.linuxtone.org;
#support php
location ~ .*\.php?$
{
include enable_php5.conf;
}
#expires static files
location ~* \.(js|css|jpg|jpeg|gif|png)$ {
if (-f $request_filename) {
access_log off;
expires 1d;
break;
}
}
location ~ ^/(tongji)/{
root /data/www/wwwroot/count;
auth_basic "LT-COUNT-TongJi";
auth_basic_user_file/usr/local/nginx/conf/htpasswd/tongji;
}
}
4.如何实现Nginx目录列表 在相关虚拟主机配置文件加入如下设置即可，更多请参考官方wiki
复制内容到剪贴板代码:
location/{ autoindexon;
}
5.修改Nginx的header伪装服务器复制内容到剪贴板代码:
cd nginx-0.6.31/src/core #define NGINX_VERSION "1.2"
#define NGINX_VER "LTWS/" NGINX_VERSION
仍后重新编译nginx即可，查看一下效果: # curl -I http://bbs.linuxtone.org
复制内容到剪贴板代码:
HTTP/1.1 200 OK Server: LTWS/1.2
Date: Mon, 23 Jun 2008 06:11:17 GMT
Content-Type: text/html; charset=gb2312
Transfer-Encoding: chunked
Connection: keep-alive
Set-Cookie: lt__sid=cJN2FT; expires=Mon, 30-Jun-2008 06:11:17 GMT; path=/
Set-Cookie: lt__onlineusernum=228; expires=Mon, 23-Jun-2008 06:16:17 GMT; path=/
6.减小nginx编译后的文件大小 (Reduce file>默认的nginx编译选项里居然是用debug模式(-g)的（debug模式会插入很多跟踪和ASSERT之类），编译以后一个nginx有好几兆。
去掉nginx的debug模式编译，编译以后只有480K(nginx-0.6.31 , gcc4)。
# du -sh nginx
480K nginx
在auto/cc/gcc，最后几行有：
复制内容到剪贴板代码:
# debug CFLAGS="$CFLAGS -g"
注释掉或删掉这几行，重新编译即可 7.Nginx日志处理
# crontab -l
复制内容到剪贴板代码:
59 23 * * * /usr/local/sbin/logcron.sh /dev/null 2>&1# cat /usr/local/sbin/logcron.sh复制内容到剪贴板代码:
#!/bin/bash log_dir="/data/logs"
time=`date +%Y%m%d`
/bin/mv${log_dir}/access_linuxtone.org.log ${log_dir}/access_count.linuxtone.org.$time.log
kill -USR1 `cat/var/run/nginx.pid`
更多的日志分析与处理就关注(同时欢迎你参加讨论):http://bbs.linuxtone.org/forum-8-1.html 五、基本安全设置策略
1)SSH安全策略:经常升级OpenSSH,SSH全安(修改SSH端口限制来源IP登陆，或者参考http://bbs.linuxtone.org/thread-106-1-1.html
)
2)关掉不需要的服务可以利用上文提到的脚本;iptables 封锁相关端口(推荐读CU白金大哥的两小时玩转iptables)
3)做好系统监控和审计相关的工作，做好系统自动化备份脚本，保证数据短时期可以恢复最近时间段，降低损失！
4)Linux防Arp***策略(http://bbs.linuxtone.org/thread-41-1-1.html)
5)注意(还是那句老话:安全工作从细节做起!)更多的请实时关注:http://bbs.linuxtone.org/forum-21-1.html (安全专项)
