压力测试工具ab及centos下单独安装方法 nginx和tomcat静态资源的性能测试

Apache安装包中自带的压力测试工具Apache Benchmark(简称ab)简单易用,这里采用ab作为压国测试工具.

独立安装:

ab运行需要信赖apr-util包:

# yum install apr-util

安装信赖yum-utils中的yumdownload工具如果没有找到yumdownload

# yum install yum-utils

安装完成执行以下指令

[root@localhost opt]# cd /opt/
[root@localhost opt]# mkdir abtmp
[root@localhost opt]# cd abtmp/
[root@localhost abtmp]# yum install yum-utils.noarch

[root@localhost abtmp]# yumdownloader httpd-tools*

httpd-tools-2.4.-.el7.centos..x8 |   kB   :
[root@localhost abtmp]# ls
httpd-tools-2.4.-.el7.centos..x86_64.rpm

安装:

[root@localhost abtmp]# rpm -ihv httpd-tools-2.4.-.el7.centos..x86_64.rpm

对比两数值除理1000个请求tomcat所用的时间是nginx的(3238/1624=1.99)2倍时间!
