nginx怎样实现动静分离

这篇文章将为大家详细讲解有关nginx怎样实现动静分离，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。

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；

upstream static {server 10.0.105.196:80 weight=1 max_fails=1 fail_timeout=60s;}upstream php {server 10.0.105.200:80 weight=1 max_fails=1 fail_timeout=60s;}server {listen server_name#动态资源加载80;localhostlocation ~ \.(php|jsp)$ { proxy_pass http://phpserver;proxy_set_header Host $host:$server_port; proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;}#静态资源加载location ~ \.(html|jpg|png|css|js)$ { proxy_pass http://static; proxy_set_header Host $host:$server_port; proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;}}

静态资源配置---10.0.105.196

server {listen 80;server_name localhost;location ~ \.(html|jpg|png|js|css)$ { root /var/www/nginx;}}

动态资源配置: 10.0.105.200

yum 安装php7.1

[root@nginx-server ~]#rpm -Uvh https://mirror.webtatic.com/yum/el7/epel- release.rpm

[root@nginx-server ~]#rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic- release.rpm

[root@nginx-server ~]#yum install php71w-xsl php71w php71w-ldap php71w-cli php71w-common php71w-devel php71w-gd php71w-pdo php71w-mysql php71w-mbstring php71w-bcmath php71w-mcrypt -y

[root@nginx-server ~]#yum install -y php71w-fpm [root@nginx-server ~]#systemctl start php-fpm [root@nginx-server ~]#systemctl enable php-fpm

编辑nginx的配置文件:

[root@nginx-server ~]# cd /etc/nginx/conf.d/ [root@nginx-server conf.d]# vim phpserver.conf server {

listen 80;

server_name localhost; location ~ \.php$ {

root /home/nginx/html; #指定网站目录

fastcgi_pass fastcgi_index fastcgi_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@lb01 conf]# vim nginx.confworker_processes 1;events {  worker_connections 1024;}http {  include    mime.types;  default_type application/octet-stream;  sendfile    on;  keepalive_timeout 65;upstream stack_pools {    server 172.25.254.134:80 weight=5;}upstream dynamic_pools {    server 172.25.254.135:80 weight=5;}  server {    listen    80;    server_name www.lbtest.com;    location / {      root  html;      index index.html index.htm;      proxy_set_header Host $host;      proxy_pass http://dynamic_pools;    }    location /image/ {      proxy_set_header Host $host;    proxy_pass http://stack_pools;    }    location /dynamic/ {      proxy_set_header Host $host;    proxy_pass http://dynamic_pools;    }  }}[root@lb01 conf]# nginx -s reload

根据扩展名分离

[root@lb01 conf]# vim nginx.conf worker_processes 1;events {  worker_connections 1024;}http {  include    mime.types;  default_type application/octet-stream;  sendfile    on;  keepalive_timeout 65;upstream stack_pools {    server 172.25.254.134:80 weight=5;}upstream dynamic_pools {    server 172.25.254.135:80 weight=5;}  server {    listen    80;    server_name www.lbtest.com;    location / {      root  html;      index index.html index.htm;      proxy_set_header Host $host;      proxy_pass http://dynamic_pools;    }    location ~ .*.(jpg|png|gif|css|js|swf|bmp|jsp|php|asp)$ {    proxy_set_header Host $host;    proxy_pass http://stack_pools;    }  }}[root@lb01 conf]# nginx -s reload
