本地虚拟环境开发完成之后，上线过程中需要一一安装依赖包，做个记录如下：
CentOS 安装python3.5.3
wget https://www.python.org/ftp/python/3.5.3/Python-3.5.3.tgz tar -xf Python-3.5.3.tgz cd Python-3.5.3 ./configure --prefix=/usr/local/python353 make & make install
完成安装python3.5.3，在不删除系统自带的python2.x情况下，做几个软链：
#做python3软链 ln -s /usr/local/python353/bin/python3 /usr/local/bin/ #pip3软链 ln -s /usr/local/python353/bin/pip3 /usr/local/bin/
上传程序，安装scrapy及其依赖包：
#user agent包 pip3 install fake-useragent -i https://pypi.douban.com/simple/ #pymysql包 pip3 install pymysql -i https://pypi.douban.com/simple/ #PooledDB依赖包 pip3 install DBUtils -i https://pypi.douban.com/simple/ #PIL模块依赖包 pip3 install Image -i https://pypi.douban.com/simple/
在Centos系统中安装过程中，出现一个较为淡疼的问题：系统没有安装sqlite3，故此一直提示：
解决上面问题，下载sqlite3
sudo wget http://www.sqlite.org/2017/sqlite-autoconf-3190300.tar.gz
编译安装：
tar zxvf sqlite-autoconf-3190300.tar.gz cd sqlite-autoconf-3190300 ./configure --prefix=/usr/local/sqlite3 make && make install
重新编译Python，找到Python3.5.3的安装文件路径，编辑setup.py脚本，找到 “sqlite3”
sqlite_inc_paths = [ '/usr/include', '/usr/include/sqlite', '/usr/include/sqlite3', '/usr/local/include', '/usr/local/include/sqlite', '/usr/local/include/sqlite3', ]
在最后一行加入sqlite3编译安装路径，如下：
sqlite_inc_paths = [ '/usr/include', '/usr/include/sqlite', '/usr/include/sqlite3', '/usr/local/include', '/usr/local/include/sqlite', '/usr/local/include/sqlite3', '/usr/local/sqlite3', ]
重新编译Python3.5.3:
./configure --prefix=/usr/local/python353 make && make install
