為了加快網站的解析速度，可以把動態頁面和靜態頁面由不同的服務器來解析，加快解析速度。降低原 來單個服務器的壓力。 簡單來說，就是使用正則表達式匹配過濾，然后交個不同的服務器。
1、準備環境
準備一個nginx代理 兩個http 分別處理動態和靜態。
1.配置編譯安裝的nginx為反向代理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
#動態資源加載
80;
localhost
location ~ \.(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 $proxy_add_x_forwarded_for;
}
#靜態資源加載
location ~ \.(html|jpg|png|css|js)$ { 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 $proxy_add_x_forwarded_for;
}
}
靜態資源配置---10.0.105.196
server {
listen 80;
server_name localhost;
location ~ \.(html|jpg|png|js|css)$ { root /var/www/nginx;
}
}

動態資源配置: 10.0.105.200
yum 安裝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
編輯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; #指定網站目錄
fastcgi_pass fastcgi_index fastcgi_param
#站點根目錄，取決于root配置項
include
}
}
127.0.0.1:9000; #指定訪問地址
index.php;
#指定默認文件
SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_params; #包含nginx常量定義
當訪問靜態頁面的時候location 匹配到 (html|jpg|png|js|css) 通過轉發到靜態服務器，靜態服務通過
location的正則匹配來處理請求。
當訪問動態頁面時location匹配到 .\php 結尾的文件轉發到后端php服務處理請求。
知識點擴展：
通過請求分離
[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 /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
根據擴展名分離
[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
