记录一些常用的指令

Linux按照指令来关闭某个进程

nohup python -u "main.py"    > log.out 2>&1 &

ps -ef|grep "python -u main.py"| awk '{print $2}'|xargs kill -9

 服务器批量安装
 parallel-ssh -h hosts.txt -i "/home/dell/anaconda3/bin/python -m  pip  install   -i https://pypi.tuna.tsinghua.edu.cn/simple numpy==1.23.0"

docker 安装：

sudo curl -fsSL https://gitee.com/tech-shrimp/docker_installer/releases/download/latest/linux.sh| bash -s docker docker

拉镜像

docker run -p 9030:9030 -p 8030:8030 -p 8040:8040 -itd --name quickstart docker.m.daocloud.io/starrocks/allin1-ubuntu

启动目录文件访问

python3 -m http.server 8000 --bind 0.0.0.0 --directory .

 

 

 

报错：

DataDirError: Valid PROJ data directory not found. Either set the path using the environmental variable PROJ_LIB or with `pyproj.datadir.set_data_dir`.

 

 

import os
os.environ['PROJ_LIB'] = "D:\\anaconda\\envs\\geo\\Library\\share\\proj"

import pyproj
pyproj.datadir.get_data_dir()

 

 

查看表格需要用：

 alias show_csv='python -c "import pandas as pd,sys;df=pd.read_csv(sys.argv[1]);print(df.iloc[[0,5,-5,-1]].to_string(index=False,header=True))"'

 

查看允许的电源策略

 cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors

查看现在的策略
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor | uniq

设置成高性能策略
echo 'performance' | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

查看每一个+平均平率
