CentOS7之Scrapy爬蟲部署

scrapyd

安裝:

sudo pip install scrapyd

配置:

#文件~/.scrapyd.conf
#內容以下:
[scrapyd]
eggs_dir    = /home/sirius/scrapyd/eggs
logs_dir    = /home/sirius/scrapyd/logs
items_dir   = /home/sirius/scrapyd/items
jobs_to_keep = 5
dbs_dir     = /home/sirius/scrapyd/dbs
max_proc    = 0
max_proc_per_cpu = 4
finished_to_keep = 50
poll_interval = 5
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

supervisor

守護進程，用這個的緣由實在是由於scrapyd太脆弱了，一看不住就掛了

安裝:

sudo pip install supervisor

配置:

sudo mkdir -p /etc/supervisor/

＃導入默認配置
sudo su - root -c "echo_supervisord_conf > /etc/supervisor/supervisord.conf"

#連接管理
[inet_http_server]         ; inet (TCP) server disabled by default
port=127.0.0.1:9001        ; (ip_address:port specifier, *:port for all iface)
;username=user              ; (default is no username (open server))
;password=123               ; (default is no password (open server))  

[supervisorctl]
;serverurl=unix:///tmp/supervisor.sock ; use a unix:// URL  for a unix socket
serverurl=http://127.0.0.1:9001 ; use an http:// url to specify an inet socket
;username=chris              ; should be same as http_username if set
;password=123                ; should be same as http_password if set
;prompt=mysupervisor         ; cmd line prompt (default "supervisor")
;history_file=~/.sc_history  ; use readline history if available

#設置管理進程
[program:scrapyd]
command=scrapyd
autostart=true
autorestart=unexpected

啓動

`建立文件/usr/lib/systemd/system/supervisord.service內容以下:

#啓動
sudo systemctl enable supervisord
sudo systemctl start supervisord

#查看

#如一切正常
|>$ scrapyd   RUNNING   pid 8059, uptime 0:02:02

#經常使用命令
