最近根据须要,使用scrapy开发了一个爬虫应用,直接使用的python2,记录一下部署环境。python
1.安装epel扩展源 scrapy
yum -y install epel-release阿里云
2.安装pipcrontab
yum -y install python-pipip
3.安装scrapy ssl
pip install scrapy开发
阿里云镜像:pip install scrapy -i http://mirrors.aliyun.com/pypi/simple --trusted-host mirrors.aliyun.com部署
4.若出现 command 'gcc' failed with exit status 1,gcc编译缺乏模块openssl
yum install gcc libffi-devel python-devel openssl-develit
5.未安装MySQLdb
yum install MySQL-python
6.若需定时脚本
crontab -e
案例:0 * * * * cd /wnet/pig && scrapy crawl price
