 2、压力测试

 常见压力测试工具:ab,http_load,autobench,webbench,loadrunner

 (1)ab 压力测试

 # ab -c 5000 -n 5000 -g nokeep5.data http://10.0.0.11/template3/index.html

 编辑 gnuplot 绘图配置文件

 # yum install gnuplot

 # vim gnuplot.txt

 set xlabel "request"

 set ylabel "response times(ms)"

 plot "/test/nokeep1.data" using 9 smooth sbezier with lines title "text test","/test/nokeep2.data"

using 9 smooth sbezier with lines title "php test","/test/nokeep3.data" using 9 smooth sbezier with

lines title "tmp1 test","/test/nokeep4.data" using 9 smooth sbezier with lines title "tmp2

test","/test/nokeep5.data" using 9 smooth sbezier with lines title "tmp3 test"

 #gnuplot gnuplot.txt

 (2)http_load 压力测试

 -p 并发进程数

 -f 总计访问次数

 (3)webbench 压力测试

 -c 指定并发连接数

 -t 运行测试时间

 # webbench -c 10000 -t 10 http://10.0.0.11/template3/index.html

 StartServers 100 \\设置启动的空闲进程数

 MinSpareServers 100 \\设置最小的空闲进程数

 MaxSpareServers 500 \\设置最大空闲进程数

 MaxRequestWorkers 500 \\允许启动的最大服务器进程数量

 MaxConnectionsPerChild 4000 \\设置进程响应多少次连接后关闭

 (3)使用缓存 cache 功能

 在编译时加上:--enable-cache --enable-mem-cache --enable-disk-cache --enable-file-cache

 在 apache 中添加功能模块

 # cd /usr/src/httpd-2.4.6/modules/cache \\进入模块源文件所在目录

 # /usr/local/httpd/bin/apxs -cia mod_cache.c cache_util.c cache_storage.c

 LoadModule cache_disk_module modules/mod_cache_disk.so

 

 <IfModule mod_cache.c>

 CacheDefaultExpire 86400

 CacheMaxExpire 172800

 CacheLastModifiedFactor 0.1

 CacheDisable /sxjy

 CacheEnable mem /template1

 CacheEnable mem /template2

 CacheEnable disk /teplate3

 MCacheMinObjectSize 10

 MCacheRemovalAlgorithm GDSF

 MCacheSize 134217728

 </IfModule>
