CentOS7- 安装WebSocket-bench 进行Socket.io的压力测试

参照: WebSocket-bench.

安装node

参照: CentOS 7 nodeJs环境相关安装.

安装websocket-bench

npm install -g websocket-bench

①安装出现error

······
make: Entering directory `/home/vagrant/.npm-global/lib/node_modules/websocket-bench/node_modules/utf-8-validate/build'
  CXX(target) Release/obj.target/validation/src/validation.o
make: g++: Command not found
make: *** [Release/obj.target/validation/src/validation.o] Error 127
······

安装 g++

sudo yum -y install gcc-c++

再次安装 OK

[vagrant@localhost vagrant]$ npm install -g websocket-bench

+ websocket-bench@0.2.0
added 5 packages from 9 contributors and updated 6 packages in 10.198s

②版本确认出现error

[vagrant@localhost vagrant]$ websocket-bench -V
bash: websocket-bench: command not found

PATH确认

[vagrant@localhost vagrant]$ echo $PATH
/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/vagrant/.local/bin:/home/vagrant/bin

通过上面的安装信息可以看到，路径需要添加　/home/vagrant/.npm-global/bin

[vagrant@localhost vagrant]$ PATH=$PATH:/home/vagrant/.npm-global/bin
[vagrant@localhost vagrant]$ export PATH

版本确认

[vagrant@localhost vagrant]$ websocket-bench -V
0.0.3

修改文件打开数

默认是 1024，推荐 60000
确认当前设置；

[vagrant@localhost vagrant]$ ulimit -n
1024

修改

[vagrant@localhost etc]$ su
Password:
[root@localhost etc]# ulimit -n 60000
[root@localhost etc]# su vagrant
[vagrant@localhost etc]$
[vagrant@localhost etc]$ ulimit -n
60000

执行测试

websocket-bench -a 2500 -c 200 http://localhost:3000
