nginx实现动静分离实例讲解
为了加快网站的解析速度，可以把动态页面和静态页面由不同的服务器来解析，加快解析速度。降低原来单个服务器的压力。简单来说，就是使用正则表达式匹配过滤，然后交个不同的服务器。
1、准备环境
准备一个nginx代理两个http分别处理动态和静态。
1.配置编译安装的nginx为反向代理upstream；
upstreamstatic{
server10.0.105.196:80weight=1max_fails=1fail_timeout=60s;
}
upstreamphp{
server10.0.105.200:80weight=1max_fails=1fail_timeout=60s;
}
server{
listenserver_name
#动态资源加载
80;
localhost
location~\.(php|jsp)${proxy_passhttp://phpserver;
proxy_set_headerHost$host:$server_port;proxy_set_headerX-Real-IP$remote_addr;
proxy_set_headerX-Forwarded-For$proxy_add_x_forwarded_for;
}
#静态资源加载
location~\.(html|jpg|png|css|js)${proxy_passhttp://static;proxy_set_headerHost$host:$server_port;proxy_set_headerX-Real-IP$remote_addr;
proxy_set_headerX-Forwarded-For$proxy_add_x_forwarded_for;
}
}
静态资源配置---10.0.105.196
server{
listen80;
server_namelocalhost;
location~\.(html|jpg|png|js|css)${root/var/www/nginx;
}
}
上传图片
动态资源配置:10.0.105.200
yum安装php7.1
[root@nginx-server~]#rpm-Uvhhttps://mirror.webtatic.com/yum/el7/epel-release.rpm
[root@nginx-server~]#rpm-Uvhhttps://mirror.webtatic.com/yum/el7/webtatic-release.rpm
[root@nginx-server~]#yuminstallphp71w-xslphp71wphp71w-ldapphp71w-cliphp71w-commonphp71w-develphp71w-gdphp71w-pdophp71w-mysqlphp71w-mbstringphp71w-bcmathphp71w-mcrypt-y
[root@nginx-server~]#yuminstall-yphp71w-fpm[root@nginx-server~]#systemctlstartphp-fpm[root@nginx-server~]#systemctlenablephp-fpm
编辑nginx的配置文件:
[root@nginx-server~]#cd/etc/nginx/conf.d/[root@nginx-serverconf.d]#vimphpserver.confserver{
listen80;
server_namelocalhost;location~\.php${
root/home/nginx/html;#指定网站目录
fastcgi_passfastcgi_indexfastcgi_param
#站点根目录，取决于root配置项
include
}
}
127.0.0.1:9000;#指定访问地址
index.php;
#指定默认文件
SCRIPT_FILENAME$document_root$fastcgi_script_name;
fastcgi_params;#包含nginx常量定义
当访问静态页面的时候location匹配到(html|jpg|png|js|css)通过转发到静态服务器，静态服务通过
location的正则匹配来处理请求。
当访问动态页面时location匹配到.\php结尾的文件转发到后端php服务处理请求。
知识点扩展：
通过请求分离
[root@lb01conf]#vimnginx.conf
worker_processes1;
events{
worker_connections1024;
}
http{
include mime.types;
default_typeapplication/octet-stream;
sendfile on;
keepalive_timeout65;
upstreamstack_pools{
server172.25.254.134:80weight=5;
}
upstreamdynamic_pools{
server172.25.254.135:80weight=5;
}
server{
listen 80;
server_namewww.lbtest.com;
location/{
root html;
indexindex.htmlindex.htm;
proxy_set_headerHost$host;
proxy_passhttp://dynamic_pools;
}
location/image/{
proxy_set_headerHost$host;
proxy_passhttp://stack_pools;
}
location/dynamic/{
proxy_set_headerHost$host;
proxy_passhttp://dynamic_pools;
}
}
}
[root@lb01conf]#nginx-sreload
根据扩展名分离
[root@lb01conf]#vimnginx.conf
worker_processes1;
events{
worker_connections1024;
}
http{
include mime.types;
default_typeapplication/octet-stream;
sendfile on;
keepalive_timeout65;
upstreamstack_pools{
server172.25.254.134:80weight=5;
}
upstreamdynamic_pools{
server172.25.254.135:80weight=5;
}
server{
listen 80;
server_namewww.lbtest.com;
location/{
root html;
indexindex.htmlindex.htm;
proxy_set_headerHost$host;
proxy_passhttp://dynamic_pools;
}
location~.*.(jpg|png|gif|css|js|swf|bmp|jsp|php|asp)${
proxy_set_headerHost$host;
proxy_passhttp://stack_pools;
}
}
}
[root@lb01conf]#nginx-sreload
