nginx动静分离初尝试

nginx监听80端口，tomcat监听9080端口，tomcat下有个ROOT目录，目录结构如下：



nginx的配置文件：

user root;
worker_processes 1;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;

events {
worker_connections 1024;
}

http {
include mime.types;
default_type application/octet-stream;

log_format access '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for';
access_log logs/access.log access;

sendfile on;
#tcp_nopush on;

#keepalive_timeout 0;
keepalive_timeout 65;#静态内容保持长连接

#gzip on;

server {
listen 80;
server_name localhost;
#charset koi8-r;

location / { ###所以jsp、do的动态请求都交给后面的tomcat处理
proxy_pass http://localhost:9080; proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size 10m;
client_body_buffer_size 128k;
proxy_connect_timeout 90;
proxy_send_timeout 90;
proxy_read_timeout 90;
proxy_buffer_size 4k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
}

location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ { ###所以的静态文件人gif、jpg等都在本地打开，存放的目录为/root/tools/tomcat7/webapps/ROOT，保存时间为30天
root /root/tools/tomcat7/webapps/ROOT;
expires 30d;
}

location ~ .*\.(js|css)?$ {
root /root/tools/tomcat7/webapps/ROOT;
expires 1h;
}

}
}

测试动静分离是否成功：

访问http://192.168.1.128/index.jsp

tomcat的access.log

127.0.0.1 - - [14/Oct/2014:18:43:05 +0800] "GET /index.jsp HTTP/1.0" 200 436

nginx的access.log

192.168.1.1 - - [14/Oct/2014:18:33:56 +0800] "GET /js/jquery-1.10.1.min.js HTTP/1.1" 304 0 "http://192.168.1.128/index.jsp" "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:32.0) Gecko/20100101 Firefox/32.0" -

192.168.1.1 - - [14/Oct/2014:18:43:04 +0800] "GET /index.jsp HTTP/1.1" 200 436 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:32.0) Gecko/20100101 Firefox/32.0" -

结论：以jsp结尾的请求去找tomcat了，以js、jpg结尾的请求没有找tomcat，动静分离配置成功。
