一、编译安装nginx
cd /usr/local/src
wget http://nginx.org/download/nginx-1.6.3.tar.gz
tar -zxvf nginx-1.6.3.tar.gz
cd nginx-1.6.3
./configure --prefix=/usr/local/nginx --with-file-aio --with-http_ssl_module --with-http_image_filter_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_auth_request_module --with-http_random_index_module --with-http_secure_link_module --with-http_stub_status_module --with-http_degradation_module --with-http_perl_module --with-mail --with-mail_ssl_module --with-pcre
make && make install
二、安装apache的httpd服务器
wget apache.fayea.com/apr/apr-1.5.2.tar.gz
wget apache.fayea.com/apr/apr-util-1.5.4.tar.gz
wget apache.fayea.com/httpd/httpd-2.4.16.tar.gz
#安装apache的时候必须先安装apr，在安装apr-util，最后安装httpd
(1)安装apr
tar -zxvf apr-1.5.2.tar.gz
cd apr-1.5.2
./cponfigure --prefix=/usr/local/apr
make && make install
（2）安装apr-util
tar -zxvf apr-util-1.5.4.tar.gz
cd apr-util-1.5.4
./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr/
make && make install
（3）安装httpd
tar -zxvf httpd-2.4.16.tar.gz
cd httpd-2.4.16
./configure --prefix=/usr/local/http --sysconfdir=/etc/httpd --enable-rewrite --enable-so --enable-ssl --enable-cgi --enable-cgid --enable-modules=most --enable-mods-shared=most --enable-mpms-shared=all --with-apr=/usr/local/apr --with-apr-utils=/usr/local/apr-util/
make && make install
#安装完成之后为httpd提供启动脚本
vim /etc/init.d/httpd
#!/bin/bash

exit 1
esac
exit $RETVAL
chmod +x /etc/init.d/httpd #赋予可执行权限
vim /etc/profile.d/httpd.sh #开机加入path变量httpd的安装路径
三、安装php
wget mirrors.sohu.com/php/php-5.3.29.tar.gz
tar -zxvf php-5.3.29.tar.gz
cd php-5.3.29
./configure --prefix=/usr/local/php --with-mysql=/usr/local/mysql --with-openssl --with-mysqli=/usr/local/mysql/bin/mysql_config --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --enable-sockets --with-apxs2=/usr/local/http/bin/apxs --with-mcrypt --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-bz2 --enable-maintainer-zts --with-mhash --with-gd --with-iconv-dir --enable-magic-quotes --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-gd-native-ttf --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --without-pear --with-gettext --disable-fileinfo --enable-exif --enable-dom #重要的是with-apxs2=/usr/local/http/bin/apxs 选项，代表把php编译成httpd的模块使用
make && make install
cp /usr/local/src/php-5.3.29/php.ini-production /etc/php.ini
vim /etc/httpd/httpd.conf #修改httpd配置文件，在大概158行左右去掉注释，使apache加载php的模块
LoadModule php5_module modules/libphp5.so
#在http配置文件大概385行左右的位置加入下面的配置让httpd支持php
AddType application/x-httpd-php .php
AddType image/x-icon .ico
AddType application/x-http-php-source .phps
保存退出
重启httpd
service httpd restart
apachectl -M 查看是否加载了php
到httpd的网页目录下创建一个index.php文件，在浏览器打开。如果可以访问就是可以解析php程序了。
#index.php文件内容：
<?php
phpinfo();
?>
到此安装结束。下面是配置负载均衡和动静分离
一、nginx配置
先说说架构，前端一个nginx（192.168.10.100）实现轮询算法的负载均衡，所有请求由前端的nginx接受根据轮询的方式交给后端的应用服务器（192.168.10.233、192.168.10.234），静态请求由后端的nginx响应，而动态请求通过转发至后端的httpd服务器进行处理之后在返回给nginx。由nginx把结果返回给客户。我用两个虚拟主机，分别是a.pl.com和img.pl.com
（1）前端负载nginx配置（192.168.10.100）定义后端的应用服务器集群和负载方式
vim /usr/local/nginx/conf/nginx.conf
upstream a.pl.com {
server 192.168.10.233:80 weight=50 max_fails=5 fail_timeout=20s;
server 192.168.10.234:80 weight=50 max_fails=5 fail_timeout=20s;
}
upstream b.pl.com {
server 192.168.10.233:80 weight=50 max_fails=5 fail_timeout=20s;
server 192.168.10.234:80 weight=50 max_fails=5 fail_timeout=20s;
}
___________________________________________________________________________________________
（2）后端nginx服务器配置（192.168.10.233）
#定义两个虚拟主机，在每个server段中配置一个location，所有以.php结尾的页面全部交给apache来处理
server {
listen 80;
server_name a.pl.com;
index index.html index.php;
root /data/wwwroot/polyguide;
access_log /var/log/nginx/access_cd.polyguide.com.cn.log;
location / {
if (!-e $request_filename)
{
rewrite ^/(.*\.(js|ico|gif|jpg|png|css|bmp|html|xls)$) /$1 last;
rewrite ^/(.*) /index.php?$1 last;
rewrite ^.*$ /index.php last;
}
}
location ~ .*\.php$ {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://127.0.0.1:8080;
}
}
server {
listen 80;
server_name img.pl.com;
access_log /var/log/nginx/img_access.log;
location / {
root /data/fastdfs;
index index.html index.htm;
}
location ~* /group1/M00/ {
root /data/fastdfs;
ngx_fastdfs_module;
}
location ~ .*\.php$ {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://127.0.0.1:8080;
}
}
二、后端apache应用服务器（192.168.10.233）
（1）编辑httpd主配置文件
vim /etc/httpd/httpd.conf
___________________________________________________________________________________________
大概224行左右，注释掉DocumentRoot
DocumentRoot "/data/wwwroot/polyguide"
大概477行左右，去掉注释，使apache开启虚拟主机功能
Include /etc/httpd/extra/httpd-vhosts.conf
（2）编辑httpd虚拟主机配置文件
vim /etc/httpd/extra/httpd-vhosts.conf
<VirtualHost 127.0.0.1:8080> #设置虚拟主机的监听地址和端口，由于httpd不直接向外通信，只是接收nginx转发的动态请求，所以监听在本地地址。
ServerName a.pl.com #基于域名的虚拟主机
DocumentRoot "/data/wwwroot/polyguide"
<Directory "/data/wwwroot/polyguide">
Options none
AllowOverride none
Require all granted #允许所有用户访问
</Directory>
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule ^/static/(.*) /static/$1 [L]
RewriteRule ^/uploadtmp/(.*) /uploadtmp/$1 [L]
RewriteRule ^/ueditor/(.*) /ueditor/$1 [L]
RewriteRule ^/crontab/(.*) /crontab/$1 [L]
RewriteRule ^/robots/(.*) /robots/$1 [L]
#RewriteRule ^(.*)$ /uploadtmp/$1 [L] #should use this
RewriteRule ^(.*)$ /uploadtmp/index2.php [L] #this is test rewrite rules
</IfModule>
ErrorLog "/var/log/http/a.pl-error_log" #httpd错误日志的位置
CustomLog "/var/log/http/a.pl-access_log" combined #访问日志位置
</VirtualHost>
<VirtualHost 127.0.0.1:8080> #第二个虚拟主机
ServerName img.pl.com
DocumentRoot "/data/fastdfs" #网页文件的主目录
<Directory "/data/fastdfs">
Options none
AllowOverride none
Require all granted
</Directory>
<Location /M00>
sethandler fastdfs #这个是FastDFS的设置
</Location>
ErrorLog "/var/log/http/img.pl-error_log"
CustomLog "/var/log/http/img.pl-access_log" combined
</VirtualHost>
另一台配置就不写了，到此，配置完毕，现在分别访问在nginx上的静态页面和apache上的动态页面测试。新手~写的不好。请各位大神勿喷，有什么错误和需要改正的请留言。谢谢~
