pyspider是Python中强大Web爬虫框架,而且支持分布式架构。python
在安装pyspider时爬过一些坑,好比使用pip install pyspider时,python的版本要求在3.6及如下,由于async等已是python3.7的关键字;
使用git clone代码安装pyspider,python3 setup.py intall
,使用过程会遇到ssl证书的问题,总而言之,可能会遇到版本兼容问题。mysql
docker network create --driver bridge pyspider mkdir -p /volume1/docker/Pyspider/mysql/{conf,logs,data}/ /volume1/docker/Pyspider/redis/ docker run --network=pyspider --name redis -d -v /volume1/docker/Pyspider/redis:/data -p 6379:6379 redis docker run --network pyspider -p 33060:3306 --name pymysql -v /volume1/docker/Pyspider/mysql/conf/my.cnf:/etc/mysql/my.cnf -v /volume1/docker/Pyspider/mysql/logs:/logs -v /volume1/docker/Pyspider/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=root123 -d mysql docker run --network=pyspider --name scheduler -d -p 23333:23333 --restart=always binux/pyspider --taskdb "mysql+taskdb://pyspider:py1234@192.168.2.4:33060:33060/taskdb" --resultdb "mysql+projectdb://pyspider:py1234@192.168.2.4:33060:33060/resultdb" --projectdb "mysql+projectdb://pyspider:py1234@192.168.2.4:33060:33060/projectdb" --message-queue "redis://redis:6379/0" scheduler --inqueue-limit 10000 --delete-time 3600
使用docker-compose部署nginx

若是想建立更多的fetcher, result_work, phantomjs容器实例,能够使用: docker-compose scale phantomjs=2 processor=4 result-worker=2 docker-compose会自动帮你建立2个phantomjs服务,4个processor服务,2个result-worker服务;haproxy会自动实现负载均衡web
