一、Python環境安裝
airflow依賴Python3，所以安裝之前需要保證服務器有Python環境
#安裝Python3 #安裝依賴環境 yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel #下載安裝包 wget https://www.python.org/ftp/python/3.6.8/Python-3.6.8.tgz #創建python3目錄 mkdir -p /usr/local/python3 #解壓縮 tar -zxvf Python-3.6.8.tgz #編譯安裝,需要c環境 yum install gcc cd Python-3.6.8 ./configure --prefix=/usr/local/python3 make make install #建立python3的軟鏈 ln -s /usr/local/python3/bin/python3 /usr/bin/python3 ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3 #將/usr/local/python3/bin加入PATH ... PATH=$PATH:$HOME/bin:/usr/local/python3/bin export PATH ... source ~/.bash_profile #檢查是否生效 python3 -V pip3 -V
#systemctl自啟動報錯解決
#Q:No such file or directory: 'airflow': 'airflow'
#A:將python3的路徑加入到PATH：which python3
export PATH=$PATH:/root/miniconda3/envs/py36/bin/
source /etc/profile
二、依賴包安裝
airflow依賴大量第三方包，如果都一一安裝較為困難，本次采用安裝miniconda包，可以達到事半功倍的效果
wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh bash Miniconda3-latest-Linux-x86_64.sh source ~/.bashrc conda create -n py36 python=3.6 anaconda conda activate py36
安裝完miniconda之后，就可以安裝airflow的包了
pip install 'apache-airflow[celery]' pip install 'apache-airflow[redis]' pip install 'apache-airflow[mysql]'
