centos安装airflow
2024-04-30 06:02:08
首先需要安装python，pip，建议安装python3。我这里因为之前使用datax，安装的时python2，图省事就没有升级到python3。下面介绍安装过程。
安装airflow
之后直接pip install apache-airflow进行安装，结果报一堆下面的错

解决方案也很简单，运行以下命令再重新安装即可：
sudo yum -y install python2-devel
python3类似
安装完成之后既可以查看airflow的版本号：
$ airflow version
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Airflow 1.10 will be the last release series to support Python 2
1.10.10
airflow默认是安装再~/airflow下的，可以通过设置export AIRFLOW_HOME=xxx修改安装目录。我这里没有改：
$ ll ~/airflow/
total 40
-rw-r--r-- 1 asn admin 36403 Jun 6 18:12 airflow.cfg
drwxr-xr-x 3 asn admin 23 Jun 6 18:12 logs
-rw-r--r-- 1 asn admin 2524 Jun 6 18:12 unittests.cfg
接下来进入初始化步骤。
初始化
$ airflow initdb

默认使用的数据库是sqlite，与airflow.executors.sequential_executor.SequentialExecutor绑定在一起，只支持任务实例的顺序执行，不支持并行化，因此后续可以通过配置修改改mysql数据库。
