Benchmarking localhost [through 218.19.166.24:3129] (be patient)
socket: Too many open files (24)
提示出错 上网查到是socket系统默认为1024 大于该直就报错
网上修改办法为ulimit -n 35768
但是
yuan@yuan-desktop:~$ ulimit -n 35768
bash: ulimit: open files：无法修改限制：操作不允许
yuan@yuan-desktop:~$ sudo ulimit -n 35768
sudo: ulimit: command not found
yuan@yuan-desktop:~$
无奈
还有方法是
