Python3安装与配置venv虚拟环境

创建安装目录

mkdir -p /usr/local/python3  && cd /usr/local/python3/

下载适宜的版本(传送门)

wget https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tgz

解压

tar -vzxf Python-3.6.6.tgz && cd Python-3.6.6

config

./configure --prefix=/usr/local/python3/Python-3.6.6

安装

make  &&  make install

配置Python3软连接

ln -s /usr/local/python3/Python-3.6.6/bin/python3.6 /usr/bin/python3
ln -s /usr/local/python3/Python-3.6.6/bin/pip3 /usr/bin/pip3

验证python3环境

[root@localhost bin]# python3
Python 3.6.6 (default, Nov 14 2018, 18:41:59) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-23)] on linux

升级 pip

#-i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com 指定使用阿里云的源，可以不加
pip3 install --upgrade pip -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com

安装venv

pip3 install virtualenv -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com

创建代码目录

mkdir -p /data/code/python && cd  /data/code/python

创建venv虚拟工作环境

python3 -m venv /data/code/python/venv_proxy_pool

查看 venv虚拟环境

[root@oracledb venv_proxy_pool]# ls -l

拉代码

cd /data/code/python/venv_proxy_pool/
git clone  https://github.com/jhao104/proxy_pool.git

升级venv pip3

/data/code/python/venv_proxy_pool/bin/pip3 install --upgrade pip -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com

安装环境依赖

/data/code/python/venv_proxy_pool/bin/pip3 install -r /data/code/python/venv_proxy_pool/proxy_pool/requirements.txt -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com

运行

cd /data/code/python/venv_proxy_pool/proxy_pool/Run/
/data/code/python/venv_proxy_pool/bin/python3 main.py
