ubuntu安装airflow 2.6.3-526互联

用的是docker容器安装-系统是ubuntu 因为centos的python环境特恶心

容器里先换apt源-这里自己找百度吧

apt install python3-pip

python3 -m pip install --upgrade pip -i https://pypi.tuna.tsinghua.edu.cn/simple

安装指定版本

pip3 install apache-airflow==2.6.3 -i https://pypi.tuna.tsinghua.edu.cn/simple

一般情况不会有报错

如果缺少依赖就安装相应依赖就行，我用ubuntu没有遇到这种问题，centos就是各种问题

安装完成后运行输出命令airflow

输出没有报错

Usage: airflow [-h] GROUP_OR_COMMAND ...

Positional Arguments:

GROUP_OR_COMMAND

Groups: celery Celery components config View configuration connections Manage connections dags Manage DAGs db Database operations jobs Manage jobs kubernetes Tools to help run the KubernetesExecutor pools Manage pools providers Display providers roles Manage roles tasks Manage tasks users Manage users variables Manage variables Commands: cheat-sheet Display cheat sheet dag-processor Start a standalone Dag Processor instance info Show information about current Airflow and environment kerberos Start a kerberos ticket renewer plugins Dump information about loaded plugins rotate-fernet-key Rotate encrypted connection credentials and variables scheduler Start a scheduler instance standalone Run an all-in-one copy of Airflow sync-perm Update permissions for existing roles and optionally DAGs triggerer Start a triggerer instance version Show the version webserver Start a Airflow webserver instance

Optional Arguments:

-h, --help show this help message and exit

就是正常的

然后初始化airflow（我用的是mysql的外部数据库，需修改配置文件）

vim airflow.cfg

sql_alchemy_conn = mysql+pymysql://root:xxx@xxx/airflow ##这个airflow确保是空库===========pymysql这个插件根据自己喜好选择我用的是pymysql而已

开始初始化

airflow db init

一般第一次执行都没有啥报错如果有提示没有pymysql 模块就直接安装一个

pip install pymysql -i https://pypi.tuna.tsinghua.edu.cn/simple

继续初始化

然后启动webserver
