Scrapy可视化管理软件SpiderKeeper

通常开发好的Scrapy爬虫部署到服务器上，要不使用nohup命令，要不使用scrapyd。如果使用nohup命令的话，爬虫挂掉了，你可能还不知道，你还得上服务器上查或者做额外的邮件通知操作。如果使用scrapyd，就是部署爬虫的时候有点复杂，功能少了点，其他还好。

SpiderKeeper是一款管理爬虫的软件，和scrapinghub的部署功能差不多，能多台服务器部署爬虫，定时执行爬虫，查看爬虫日志，查看爬虫执行情况等功能。

一、运行环境

• Centos7
• Python2.7
• Python3.6
  注意：supervisor用的是Python2.7，scrapyd用的是Python3.6，需要自行编译安装。Python3具体安装自行百度。

二、安装依赖

1、supervisor pip install supervisor
2、scrapyd pip3 install scrapyd
3、SpiderKeeperpip3 install SpiderKeeper

三、配置scrapyd

1、新建scrapyd的配置文件：

[scrapyd]
eggs_dir    = eggs
logs_dir    = logs
items_dir   =
jobs_to_keep = 5
dbs_dir     = dbs
max_proc    = 0
max_proc_per_cpu = 4
finished_to_keep = 100
poll_interval = 5.0
bind_address = 0.0.0.0
http_port   = 6800
debug       = off
runner      = scrapyd.runner
application = scrapyd.app.application
launcher    = scrapyd.launcher.Launcher
webroot     = scrapyd.website.Root

[services]
schedule.json     = scrapyd.webservice.Schedule
cancel.json       = scrapyd.webservice.Cancel
addversion.json   = scrapyd.webservice.AddVersion
listprojects.json = scrapyd.webservice.ListProjects
listversions.json = scrapyd.webservice.ListVersions
listspiders.json  = scrapyd.webservice.ListSpiders
delproject.json   = scrapyd.webservice.DeleteProject
delversion.json   = scrapyd.webservice.DeleteVersion
listjobs.json     = scrapyd.webservice.ListJobs
daemonstatus.json = scrapyd.webservice.DaemonStatus

四、配置supervisor

1、创建配置的文件夹和配置文件

mkdir /etc/supervisor
echo_supervisord_conf > /etc/supervisor/supervisord.conf

2、编辑配置文件vim /etc/supervisor/supervisord.conf

;[include]
;files = relative/directory/*.ini

改为

[include]
files = conf.d/*.conf

3、新建conf.d文件夹mkdir /etc/supervisor/conf.d
4、添加scrapyd的配置文件vim /etc/supervisor/conf.d/scrapyd.conf

[program:scrapyd]
command=/usr/local/python3.5/bin/scrapyd
directory=/opt/SpiderKeeper
user=root
stderr_logfile=/var/log/scrapyd.err.log
stdout_logfile=/var/log/scrapyd.out.log

5、添加spiderkeeper的配置文件vim /etc/supervisor/conf.d/spiderkeeper.conf

[program:spiderkeeper]
command=spiderkeeper --server=http://localhost:6800
directory=/opt/SpiderKeeper
user=root
stderr_logfile=/var/log/spiderkeeper.err.log
stdout_logfile=/var/log/spiderkeeper.out.log

6、启动supervisor，supervisord -c /etc/supervisor/supervisord.conf

五、使用

1、登录http://localhost:5000
2、新建project
3、打包爬虫文件
pip3 install scrapyd-client
scrapyd-deploy --build-egg output.egg
4、上传打包好的爬虫egg文件

SpiderKeeper可以识别多台服务器的scrapyd，具体多加--server就好。
