使用conda env的apache-airflow systemd文件

问题描述

我正在尝试使用systemd在Ubuntu 16.04文件上运行 apache-airflow 。我大致遵循了，并安装/设置了以下内容：

I'm trying to run apache-airflow on a Ubuntu 16.04 file, using systemd. I roughly followed this tutorial and installed/setup the following:

Miniconda 2，64位

已安装gcc（ sudo apt-get install gcc ）

Conda环境，使用教程的 yml 文件

Miniconda 2, 64-bit
Installed gcc (sudo apt-get install gcc)
Conda environment, using the yml file of the tutorial

在以下conda环境中：

Within the following conda environment:

export AIRFLOW_HOME = / home / ubuntu / airflow

当我测试气流时，一切正常：

When I test Airflow, everything works fine:

airflow webserver --port 8080

但是每当我尝试使用systemd文件，它失败。据我所知，systemd文件利用了conda环境。我的systemd文件如下所示：

But whenever I try to launch airflow using a systemd file, it fails. The systemd file makes use of the conda environment, as far as I understand correctly. My systemd file looks as follows:

[Unit]
Description=Airflow webserver daemon

[Service]
User=ubuntu
Group=ubuntu
Type=simple
ExecStart=/home/ubuntu/miniconda2/envs/airflow-tutorial/bin/airflow webserver --port 8080
Restart=on-failure
RestartSec=5s
PrivateTmp=true

[Install]
WantedBy=multi-user.target

当我启动/启用systemd守护程序时，状态返回以下错误：

When I start/enable the systemd daemon, status returns the following error:

airflow-webserver.service - Airflow webserver daemon
   Loaded: loaded (/etc/systemd/system/airflow-webserver.service; enabled; vendor preset: enabled)
   Active: activating (auto-restart) (Result: exit-code) since Thu 2018-09-13 08:59:00 UTC; 1s ago
  Process: 18410 ExecStart=/home/ubuntu/miniconda2/envs/airflow-tutorial/bin/airflow webserver --port 8080 (code=exited, status=1/FAILURE)
 Main PID: 18410 (code=exited, status=1/FAILURE)

Sep 13 08:59:00 ip-172-31-46-255 systemd[1]: airflow-webserver.service: Main process exited, code=exited, status=1/FAILURE
Sep 13 08:59:00 ip-172-31-46-255 systemd[1]: airflow-webserver.service: Unit entered failed state.
Sep 13 08:59:00 ip-172-31-46-255 systemd[1]: airflow-webserver.service: Failed with result 'exit-code'.

推荐答案

以下是 airflow-webserver.service ，它在虚拟环境中适用于我：

The following is airflow-webserver.service that works for me with a virtual environment:

[Unit]
Description=Airflow webserver daemon
After=network.target postgresql.service mysql.service redis.service rabbitmq-server.service
Wants=postgresql.service mysql.service redis.service rabbitmq-server.service

[Service]
PIDFile=/run/airflow/webserver.pid
EnvironmentFile=/etc/default/airflow
User=airflow
Group=airflow
Type=simple
ExecStart=/usr/bin/bash -c 'source /usr/local/airflow/venv/bin/activate ; airflow webserver --pid /run/airflow/webserver.pid'
Restart=on-failure
RestartSec=5s
PrivateTmp=true

[Install]
WantedBy=multi-user.target
