Scrapy可視化管理軟件SpiderKeeper

一般開發好的Scrapy爬蟲部署到服務器上，要不使用nohup命令，要不使用scrapyd。若是使用nohup命令的話，爬蟲掛掉了，你可能還不知道，你還得上服務器上查或者作額外的郵件通知操做。若是使用scrapyd，就是部署爬蟲的時候有點複雜，功能少了點，其餘還好。

SpiderKeeper是一款管理爬蟲的軟件，和scrapinghub的部署功能差很少，能多臺服務器部署爬蟲，定時執行爬蟲，查看爬蟲日誌，查看爬蟲執行狀況等功能。

1、運行環境

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

2、安裝依賴

一、supervisor pip install supervisor
二、scrapyd pip3 install scrapyd
三、SpiderKeeperpip3 install SpiderKeeper

3、配置scrapyd

一、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

4、配置supervisor

一、建立配置的文件夾和配置文件

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

二、編輯配置文件vim /etc/supervisor/supervisord.conf

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

改成

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

三、新建conf.d文件夾mkdir /etc/supervisor/conf.d
四、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

五、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

六、啓動supervisor，supervisord -c /etc/supervisor/supervisord.conf

5、使用

一、登陸http://localhost:5000
二、新建project
三、打包爬蟲文件
pip3 install scrapyd-client
scrapyd-deploy --build-egg output.egg
四、上傳打包好的爬蟲egg文件

SpiderKeeper能夠識別多臺服務器的scrapyd，具體多加--server就好。
