一 配置
1. nginx介绍就不多说了,我使用的是阿里云的centos ,使用yum命令安装 的,很容易。
2. nginx的配置文件:nginx.conf配置
我参考文章,点击查看
配置文件如下:# For more information on configuration, see:
# * Official English Documentation: http://nginx.org/en/docs/
# * Official Russian Documentation: http://nginx.org/ru/docs/
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log;
#error_log /var/log/nginx/error.log notice;
#error_log /var/log/nginx/error.log info;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
#负载均衡设置,暂时未用到,后面会使用到
upstream www.###.cn {
#ip_hash;
server 127.0.0.1:8080;
}
server {
listen 80;
server_name www.lexinli.cn;
index index.html index.jsp;
root /home/wwwftp/ROOT;
#配置Nginx动静分离,定义的静态页面直接从Nginx发布目录读取。
location ~ .*\.(html|htm|gif|jpg|jpeg|bmp|png|ico|txt|js|css)$
{
root /home/wwwftp/ROOT;
#expires定义用户浏览器缓存的时间为1天,如果静态页面不常更新,可以设置更长这样可以节省带宽和缓解服务器的压力
expires 1d;
}
#所有jsp、do的动态请求都交给后面的tomcat处理
location ~ (\.jsp)|(\.action)$
{
#tomcat地址
proxy_pass http://127.0.0.1:8080;
proxy_redirect off;
proxy_set_header HOST $host;
proxy_set_header X-Real-IP $remote_addr;
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 / {
# proxy_connect_timeout 3;
# proxy_send_timeout 30;
# proxy_read_timeout 30;
# proxy_pass http://www.lexinli.cn;
# }
}
# Load config files from the /etc/nginx/conf.d directory
# The default server is in conf.d/default.conf
include /etc/nginx/conf.d/*.conf;
}
配置完成后 /usr/sbin/nginx -s reload 重新加载配置文件
二. 测试效果:
测试Nginx 和Tomcat高并发的情况下处理静态页面性能如何?
采用了 Linux ab网站压力测试命令来测试一下性能
ab -c 10 -n 1000表示同时处理100个请求并运行1000次index.html文件
1.测试一下Nginx 处理静态页面的性能
访问nginx的:
ab -c 10 -n 1000 http://www.lexinli.cn/index.html
每秒请求数结果:Requests per second: 7095.22 [#/sec] (mean)
直接访问tomcat的:
ab -c 10 -n 1000 http://www.lexinli.cn:8080/index.html
每秒请求数结果:Requests per second: 1675.85 [#/sec] (mean)
静态交给Nginx处理,动态请求交给Tomcat,提高了性能
