Scrapy視覺化管理軟體SpiderKeeper

視覺化IDE

通常開發好的Scrapy爬蟲部署到伺服器上，要不使用nohup命令，要不使用scrapyd。如果使用nohup命令的話，爬蟲掛掉了，你可能還不知道，你還得上伺服器上查或者做額外的郵件通知操作。如果使用scrapyd，就是部署爬蟲的時候有點複雜，功能少了點，其他還好。

SpiderKeeper是一款管理爬蟲的軟體，和scrapinghub的部署功能差不多，能多臺伺服器部署爬蟲，定時執行爬蟲，檢視爬蟲日誌，檢視爬蟲執行情況等功能。

一、執行環境

  • Centos7
  • Python2.7
  • Python3.6
    注意：supervisor用的是Python2.7，scrapyd用的是Python3.6，需要自行編譯安裝。Python3具體安裝自行百度。

二、安裝依賴

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

三、配置scrapyd

1、新建scrapyd的配置檔案：

[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、建立配置的資料夾和配置檔案

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

2、編輯配置檔案vim /etc/supervisor/supervisord.conf

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

改為

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

3、新建conf.d資料夾mkdir /etc/supervisor/conf.d
4、新增scrapyd的配置檔案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、新增spiderkeeper的配置檔案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、啟動supervisor，supervisord -c /etc/supervisor/supervisord.conf

五、使用

1、登入http://localhost:5000
2、新建project
3、打包爬蟲檔案
pip3 install scrapyd-client
scrapyd-deploy --build-egg output.egg
4、上傳打包好的爬蟲egg檔案

SpiderKeeper可以識別多臺伺服器的scrapyd，具體多加--server就好。
