centos7安装python3.6独立的virtualenv环境

1.编译安装python3.6环境
# 安装依赖
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
# 获取编译安装python3.6.6
mkdir -p /usr/local/python3
wget https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tgz
tar xf Python-3.6.6.tgz
cd Python-3.6.6
./configure --prefix=/usr/local/python3
make && make install
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

2.安装virtualenv虚拟环境
pip3 install virtualenv
# 创建存放虚拟环境的目录
mkdir -p /usr/local/worksh/jeninks_task/akamai_api_venv

# 创建纯净的虚拟环境
/usr/local/python3/bin/virtualenv --no-site-packages --python=/usr/local/python3/bin/python3.6 /usr/local/worksh/jeninks_task/akamai_api_venv

# 进入虚拟环境安装必须的python依赖
[root@node5 akamai_api]# source ../akamai_api_venv/bin/activate
(akamai_api_venv) [root@node5 akamai_api]# pip install -r requirement.txt

(akamai_api_venv) [root@node5 akamai_api]# pip list
