Airflow 配置celery+rabbitmq

1、安装celery和rabbitmq组件

pip3 install apache-airflow[celery]

pip3 install apache-airflow[rabbitmq]

2、系统安装rabbit

1）安装 erlang

yum install -y erlang

如果报错如下：

[ ]# yum install erlang
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
 * base: mirrors.aliyun.com
 * extras: mirrors.aliyun.com
 * updates: mirrors.aliyun.com
No package erlang available.
Error: Nothing to do

则需要安装第三方软件库 epel：

# 下载
wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
# 安装完成即可
rpm -ivh epel-release-latest-7.noarch.rpm

再次执行则可以成功安装erlang了！

2）安装 rabbitmq

wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.15/rabbitmq-server-3.6.15-1.el6.noarch.rpm
rpm --import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc
yum install -y rabbitmq-server-3.6.15-1.el6.noarch.rpm

3）配置rabbitmq（设置用户名root，密码rabbitmq，创建虚拟主机airflow-rabbitmq）

[root@centos-master airflow]# /sbin/service rabbitmq-server stop
Stopping rabbitmq-server (via systemctl):                  [  OK  ]
[root@centos-master airflow]# /sbin/service rabbitmq-server start
Starting rabbitmq-server (via systemctl):                  [  OK  ]
[root@centos-master airflow]# rabbitmqctl add_user root rabbitmq
Creating user "root"
[root@centos-master airflow]# rabbitmqctl add_vhost airflow-rabbitmq
Creating vhost "airflow-rabbitmq"
[root@centos-master airflow]# rabbitmqctl set_user_tags root airflow-rabbitmq
Setting tags for user "root" to ['airflow-rabbitmq']
[root@centos-master airflow]# rabbitmqctl set_permissions -p airflow-rabbitmq root ".*" ".*" ".*"
Setting permissions for user "root" in vhost "airflow-rabbitmq"
[root@centos-master airflow]# rabbitmq-plugins enable rabbitmq_management
The following plugins have been enabled:
  amqp_client
  cowlib
  cowboy
  rabbitmq_web_dispatch
  rabbitmq_management_agent
  rabbitmq_management

4）修改airflow配置

[root@centos-master airflow]# vi airflow.cfg 
    executor = CeleryExecutor
    broker_url = amqp://root:rabbitmq@localhost:5672/airflow-rabbitmq
    result_backend = amqp://root:rabbitmq@localhost:5672/airflow-rabbitmq

　[root@centos-master airflow]# echo "export C_FORCE_ROOT="True"" >> /etc/profile
　[root@centos-master airflow]# source /etc/profile

Airflow 配置celery+redis

1.安装redis

yum -y install redis

2.修改配置文件

sudo vim /etc/redis.conf
#bind 127.0.0.1     // 注释掉，使redis允许远程访问
requirepass redis  // 修改这行，redis登录密码（自定义）

3.开启redis服务

systemctl start redis

4.python下安装redis库

pip3 install redis

5.安装celery

pip3 install celery

6.配置airflow.cfg

executor = CeleryExecutor
broker_url = redis://127.0.0.1:6379/0
result_backend = redis://127.0.0.1:6379/0
