很好用的压力测试工具webbench

1.安装

wget http://blog.s135.com/soft/linux/webbench/webbench-1.5.tar.gz
tar zxvf webbench-1.5.tar.gz
cd webbench-1.5
make && make install

如果在编译webbench的时候，出现/bin/sh: ctags: command not found，如下所示

[root@webbench-1.5]# make
cc -Wall -ggdb -W -O   -c -o webbench.o webbench.c
webbench.c: In function ‘alarm_handler’:
webbench.c:77: warning: unused parameter ’signal’
cc -Wall -ggdb -W -O   -o webbench webbench.o
ctags *.c
/bin/sh: ctags: command not found
make: [tags] Error 127 (ignored)

是没安装ctags组件，使用yum -y install ctags,解决问题

如果安装了ctags, 仍然报错:

install -s webbench /usr/local/bin
install -m 644 webbench.1 /usr/local/man/man1
install: cannot create regular file `/usr/local/man/man1′: No such file or directory
make: *** [install] Error 1

解决方法
mkdir -m 644 -p /usr/local/man/man1

安装好使用方法

webbench -c 500 -t 30 http://127.0.0.1/test.jpg

参数说明：-c表示并发数，-t表示时间(秒)
