我已经通过github源安装了airflow。我已经通过mysql metadb和本地执行程序配置了airflow。当我试图启动我的When服务器时，它无法启动。

install.sh

代码语言：javascript
复制
mkdir -p ~/home
export AIRFLOW_HOME=~/airflow
cd $AIRFLOW_HOME
virtualenv env
source env/bin/activate

mkdir -p /usr/local/src/
cd /usr/local/src/
git clone https://github.com/apache/incubator-airflow.git
cd incubator-airflow
git checkout tags/1.8.2
pip install -e .
pip install -e .[hive]
pip install -e .[gcp_api]
pip install -e .[mysql]
pip install -e .[password]
pip install -e .[celery]

airflow.cfg：

代码语言：javascript
复制
[core]
# The home folder for airflow, default is ~/airflow
airflow_home = /root/airflow
dags_folder = /root/airflow/dags

base_log_folder = /root/airflow/logs


encrypt_s3_logs = False
executor = LocalExecutor
sql_alchemy_conn = mysql://root:*****@localhost/airflow

当我尝试使用启动我的when服务器时，它显示了信号处理和现有的工作进程。

airflow 8080服务器-p 8080

您的fine服务器运行正常。工作人员以worker_refresh_interval设置的时间间隔定期“刷新”，以便他们获得新的或更新的DAG。当发生这种情况时，您将看到信号ttin (将进程增加1)总是紧跟在ttou(将进程减少1)之后，其中在删除最老的工作进程之前添加了一个新工作进程。
