2:测试准备工作
2.1:安装siege
使用压力测试工具siege(http://www.joedog.org/index/siege-home) 来验证。可以根据路径来并发重复压力测试。安装方式:
下载:wget ftp://sid.joedog.org/pub/siege/siege-latest.tar.gz
安装:
#./configure
#make && make install
[root@localhost test] siege -c 100 -r 100 -f varnish_url.txt [root@localhost test] siege -c 100 -r 100 -f nginx_url.txt
参数说明:
-c 100 并发100个用户
-r 100 重复循环100次
-f varnish_url.txt 任务列表:URL列表
2.2:构造URL
构造了536个url测试,其中1个是错误的url。
到测试机器上,
[root@localhost test] cd /data/htdocs/resources/web [root@localhost test] find . -name "*.jpg" -print > varnish_url.txt
2.3:开启nginx图片缓存方法
开启nginx的缓存图片的方法,在nginx的conf中添加:
location ~ .*\\.(gif|jpg|jpeg|png|bmp|swf|ico)$ { expires 30d; access_log off; }
