系統：centos7.4
安裝scrapyd：pip isntall scrapyd
因爲我騰訊雲上是python2與python3並存的 所以我執行的命令是：pip3 isntall scrapyd
安裝後新建一個配置文件：
sudo mkdir /etc/scrapyd
sudo vim /etc/scrapyd/scrapyd.conf
寫入如下內容：（給內容在https://scrapyd.readthedocs.io/en/stable/config.html可找到）
[scrapyd]
eggs_dir = eggs
logs_dir = logs
items_dir =
jobs_to_keep = 5
dbs_dir = dbs
max_proc = 0
max_proc_per_cpu = 10
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
主要更改bind_address=0.0.0.0
創建文件後執行命令啓動scrapyd: (scrapyd > /dev/null &) 當想要記錄輸出日誌時：(scrapyd > /root/scrapyd.log &)
坑1：當我執行完命令後報錯，說是找不到命令：
那是因爲我係統上python2與3並存，所以找不到，這時應該做軟連接：
我的python3路徑： /usr/local/python3
製作軟連接： ln -s /usr/local/python3/bin/scrapy /usr/bin/scrapy
昨晚軟連接後，執行上邊命令，又報錯：
坑2：
這個好像是那個配置文件的最後一行有問題，具體原因不大清楚，我將最後一行刪除，再次重新執行，scrapyd就跑起來了
