centos7 pyspider环境安装

Posted 2020-10-10

  PySpider 是一个我个人认为非常方便并且功能强大的爬虫框架，支持多线程爬取、JS动态解析，提供了可操作界面、出错重试、定时爬取等等的功能，使用非常人性化。

1.搭建环境：

    python版本：3.6.3

    系统环境：centos7.3

1.1.搭建python3环境：

# 下载依赖 

yum install -y ncurses-devel openssl openssl-devel zlib-devel gcc make glibc-devel libffi-devel glibc-static glibc-utils sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel libcurl-devel

# 下载python

wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tgz

#解压

tar -xf Python-3.6.3.tgz

#编译安装

 ./configure --prefix=/usr/local/python3.6 --enable-shared

make && make install

# 建立软链接

ln -s /usr/local/python3.6/bin/python3 /usr/bin/python3

echo "/usr/local/python3.6/lib" > /etc/ld.so.conf.d/python3.5.conf

ldconfig

# 验证python3

[[email protected] local]# python3

Python 3.6.3 (default, Oct  9 2017, 04:01:24) 

[GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] on linux

Type "help", "copyright", "credits" or "license" for more information.

>>> 

#pip

/usr/local/python3.6/bin/pip3 install --upgrade pip

ln -s /usr/local/python3.6/bin/pip /usr/bin/pip

1.2.安装pyspider

pip install pyspider

启动python中的pycurl模块出现如下问题：

ImportError: pycurl: libcurl link-time ssl backend (nss) is different from compile-time ssl backend (none/other)

解决方法：

pip uninstall pycurl
export PYCURL_SSL_LIBRARY=nss
pip install pycurl

1.3.安装phantomjs

官网下载：http://phantomjs.org/download.html

wget https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-2.1.1-linux-x86_64.tar.bz2

解压：

yum -y install unbzip2

bzip2 -d phantomjs-2.1.1-linux-x86_64.tar.bz2 

tar -xf phantomjs-2.1.1-linux-x86_64.tar

mv phantomjs-2.1.1-linux-x86_64 phantomjs

ln -sv /usr/local/phantomjs/bin/phantomjs /usr/bin/phantomjs

1.4.启动pyspider

由于放在公网，编辑了一个配置文件config.json ，用于登录认证

[[email protected] local]# vim config.json 

{

    "webui": {

        "port": "5000",

        "username": "abc",

        "password": "123456",

        "need-auth": true

    }

}

开启进程

nohup pyspider --config config.json &
