1、下载
https://hadoop.apache.org/releases.html
jdk: https://bell-sw.com/pages/downloads/#jdk-8-lts

2、网络配置 (/etc/hosts)

192.168.0.110 master
192.168.0.140 slave1

3、ssh免密配置

# 在master主机执行
ssh-keygen -t rsa
ssh-copy-id master
ssh-copy-id worker1

4、环境变量配置 (/etc/profile)

export JAVA_HOME=/usr/local/jdk8
export HADOOP_HOME=/usr/local/hadoop34
export LD_LIBRARY_PATH=$HADOOP_HOME/lib/native:$LD_LIBRARY_PATH
export PATH=$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$PATH

5、关闭主机防火墙

systemctl disable --now firewalld.service

1、本地环境

go run main.go

2、生产环境

# 构建
GOOS=linux GOARCH=amd64 go build -ldflags="-w -s" -o do-run main.go
# 运行
./do-run

1、拉取mysql8.0镜像

docker pull mysql:8.0

2、运行

docker run -d --name mysql8 --restart=unless-stopped -p 3307:3306 \
-v D:/dev/mysql8/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 mysql:8.0 \ 
--default-authentication-plugin=mysql_native_password

1、下载conda

wget -c https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
# 指定安装目录
bash Miniconda3-latest-Linux-x86_64.sh -p /usr/local/conda3

/usr/local/conda3/bin/conda init bash

conda config --set auto_activate_base false
conda config --set env_prompt '({name})'

2、基本命令

创建虚拟环境

conda create -n mytest python==3.10.8 -y

激活环境

conda activate mytest

退出环境

conda deactivate

环境列表

conda env list

指定虚拟环境python安装依赖包

python -m pip install 包名 -i https://mirrors.aliyun.com/pypi/simple/ --trusted-host=mirrors.aliyun.com
