# 搭建虚拟环境sbird python版本3.*

# 创建虚拟环境pyenv3
virtualenv -p /usr/bin/python3 pyenv3
# 进入虚拟环境 激活环境
cd pyenv3/
source ./bin/activate
pip install pyspider
# 若pycurl报错
yum install libcurl-devel
# 继续
pip install pyspider
# 关闭
deactivate

本人推荐用anaconda方式安装
若pyspider运行过程中出现错误，参考anaconda安装部分，至此，访问localhost:5000可看到页面。

至此，pyspider单个服务器运行环境搭建且部署完毕，启动localhost:5000进入web界面。
也可编写脚本运行，在/pyspider/supervisor/pyspider01.log查看运行状态。
2.分布式部署
刚才配置的服务器，将其命名为centos01，按照这样的配置，再分别部署两台centos02、centos03。
如下：
服务器名称 ip 说明
|
1

3
|
centos01 10.211.55.22 redis,mariaDB, scheduler
centos02 10.211.55.23 fetcher, processor, result_worker,phantomjs
centos03 10.211.55.24 fetcher, processor,,result_worker,webui
|
2.1.centos01
进入服务器centos01，经过第一步，基本环境已经搭好，首先编辑配置文件/pyspider/config.json
