    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
    Package         Version  
    --------------- ---------
    asn1crypto      0.24.0   
    certifi         2019.6.16
    cffi            1.12.3   
    chardet         3.0.4    
    configparser    3.7.4    
    cryptography    2.7      
    edgegrid-python 1.1.1    
    idna            2.8      
    ndg-httpsclient 0.5.1    
    pip             19.2.2   
    pyasn1          0.4.6

    # 后续可以直接这样调用独立环境的脚本

    [root@node5 akamai_api]# /usr/local/worksh/jeninks_task/akamai_api_venv/bin/python /usr/local/worksh/jeninks_task/akamai_api/aa.py

    centos7环境编译安装基于 python3.7.7 的virtualenv和virtualenvwrapper环境


    1. 安装基本的基础源和epel源为阿里云的mirrors
    wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
    wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

    2.安装依赖
    # bzip2-devel 一定要先安装,然后编译python,compress插件依赖

    yum install -y gcc gcc-c++ htop telnet iotop iptraf iftop libpng12 make logrotate xinetd ntsysv  sysstat perl autoconf libjpeg libjpeg-devel libpng libpng-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel e2fsprogs e2fsprogs-devel krb5-devel libidn libidn-devel libxml2 libxml2-devel libxslt-devel libevent-devel libtool libtool-ltdl bison  ntpdate  patch vim wget openssh-clients bind-utils

    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

    yum install -y mysql-devel python-devel mysql-lib
    yum install libffi-devel -y

    3.安装python3.7,最好开screen避免中断
    screen -S python

    # 获取python3.7.7源码并编译安装
    cd /usr/local/src
    wget https://www.python.org/ftp/python/3.7.7/Python-3.7.7.tgz
    tar xf Python-3.7.7.tgz
    cd Python-3.7.7
    mkdir -p /usr/local/python3

    ./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

    [root@sz_xxgc_cms_slave01_18_214 Python-3.7.7]# python3 -V
    Python 3.7.7

    4.安装虚拟环境
    # pip3 install virtualenv
    # pip3 install virtualenvwrpper

    5. 配置bashrc

    # vim ~/.bashrc

    export WORKON_HOME=$HOME/.virtualenvs
    export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
    source /usr/local/python3/bin/virtualenvwrapper.sh

    # source ~/.bashrc # 使其生效

    [root@sz_xxgc_cms_slave01_18_214 ~]# mkvirtualenv domain_check
    which: no virtualenv in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin)
    ERROR: virtualenvwrapper could not find virtualenv in your path

    解决:
    将python环境下的virtualenv拷贝至/usr/bin/目录下:

    # cd /usr/local/python3/bin
    # cp virtualenv /usr/bin/

    [root@sz_xxgc_cms_slave01_18_214 bin]# mkvirtualenv domain_check
    created virtual environment CPython3.7.7.final.0-64 in 1225ms
      creator CPython3Posix(dest=/root/.virtualenvs/domain_check, clear=False, global=False)
      seeder FromAppData(download=False, pip=latest, setuptools=latest, wheel=latest, via=copy, app_data_dir=/root/.local/share/virtualenv/seed-app-data/v1)
      activators BashActivator,CShellActivator,FishActivator,PowerShellActivator,PythonActivator,XonshActivator

    (domain_check) [root@sz_xxgc_cms_slave01_18_214 bin]# pip list
