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* Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile * base: mirrors.163.com * extras: mirrors.tuna.tsinghua.edu.cn * updates: mirrors.tuna.tsinghua.edu.cn httpd-tools-2.4.6-45.el7.centos.4.x8 | 84 kB 00:00 [root@localhost abtmp]# ls httpd-tools-2.4.6-45.el7.centos.4.x86_64.rpm
安装:
[root@localhost abtmp]# rpm -ihv httpd-tools-2.4.6-45.el7.centos.4.x86_64.rpm Preparing... ################################# [100%] Updating / installing... 1:httpd-tools-2.4.6-45.el7.centos.4 ################################# [100%]
下面对NGINX做测试:
