Nginx動靜分離
實驗拓撲：
實驗環境：
Nginx分發器 192.168.42.175 xuegod175.cn
Web1服務器 192.168.42.176 xuegod176.cn 作爲image圖片web服務器
Web2服務器 192.168.42.177 xuegod177.cn 作爲php web服務器
實驗注意：關閉iptables selinux 配置好hosts 文件，兩臺web服務器這裏均使用了nginx
實驗配置：
nginx實驗配置
[root@xuegod175 ~]# cat /usr/local/nginx/conf/nginx.conf
user nginx nginx;
worker_processes 1;

}
upstream image {

}
upstream php {
server 192.168.42.177 weight=1 max_fails=2 fail_timeout=2;
}
server {

server_name 192.168.42.175;
location / {

index index.php index.html;
}
location ~* \.php$ {
root html;
proxy_pass http://php;
}
location ~* ".(jpg|png|jpeg|gif)" {
proxy_pass http://image;
}
}
}
Web1服務器配置
[root@xuegod176 conf]# cat nginx.conf
worker_processes 1;
user nginx nginx ;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
location ~ .*\.(gif|jpg|jpeg|png)$ {
expires 24h;
access_log /usr/local/nginx/logs/images.log; 圖片日誌位置
proxy_store on;
proxy_store_access user:rw group:rw all:rw;
proxy_redirect off;
proxy_set_header Host 127.0.0.1;
client_max_body_size 10m;
client_body_buffer_size 1280k;
proxy_connect_timeout 900;

proxy_buffer_size 40k;
proxy_buffers 40 320k;

}
location ~ \.php$ {

fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
include fastcgi_params;
}
}
}配置測試文件（支持圖片）
[root@xuegod176 html]# ls
50x.html a abc.jpg bin binbin.jpeg index.html index.htmlbak nginx.conf
從客戶端進行訪問測試
說明nginx web1服務已經成功支持訪問圖片
通過分發器進行訪問測試（圖片文件是web1服務器的）
說明nginx讀寫分離已經成功 nginx分發器可以正常的讀取web1服務器的圖片文件
Web2服務器配置
爲了使nginx能夠支持訪問php環境，這裏特意安裝了lnmp環境
安裝mysql
[root@xuegod177 ]yum -y install mysql mysql-server mysql-devel
[root@xuegod177 ] /etc/init.d/mysqld start
安裝php
[root@xuegod177 ]yum install php php-mysql php-common php-gd php-mbstring php-mcrypt php-devel php-xml –y
[root@xuegod177 ]yum install php-fpm –y
[root@xuegod177 ]/etc/init.d/php-fpm start
[root@xuegod177 html]# ls
50x.html index.html index.html.bak index.php
[root@xuegod177 html]# cat index.php 創建測試文件
<?php phpinfo(); ?>
[root@xuegod177 conf]# cat nginx.conf
user nginx nginx;
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php; 使nginx 支持訪問php界面
fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
include fastcgi_params;
}
}
}Web2訪問測試：
說明177web 已經支持php 可以正常使用訪問。
動靜分離訪問進行測試
訪問nginx分發器 index.php(這個文件是177web2服務器上的)，nginx分發器可以正常讀取172 web2服務器的php 文件，說明讀寫分離已經成功。
