Django阿里云部署详解之服务器安装虚拟环境、Python

Django阿里云部署详解之服务器安装虚拟环境、Python

（本系统就是阿里云部署的）

大家照做就行，这我试了很多次才总结出来的

yum update -y
yum -y install gcc gcc-c++
yum -y groupinstall "Development tools"
yum -y install zlib zlib-devel openssl openssl-devel ncurses-devel sqlite sqlite-devel bzip2-deve readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

yum install epel-release
yum -y install nginx

yum install libffi-devel -y

wget https://www.python.org/ftp/python/3.8.1/Python-3.8.1.tgz

mkdir -p /usr/local/python3
tar -zxvf Python-3.8.1.tgz

cd Python-3.8.1
./configure --prefix=/usr/local/python3
make && make install

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

原来的pip自己备份下：
mv /usr/bin/pip /usr/bin/pip.bak
这里使用新的pip

ln -s /usr/local/python3/bin/pip3 /usr/bin/pip
pip install --upgrade pip

修改系统默认的python为自己装的版本

先找到新版本python安装位置，
然后

vi /etc/profile.d/python.sh

创建新文件，然后输入

alias python='/usr/bin/python3'  # 此处的路径为新版本python的路径，通过我上一篇文章来

查找此路径
重启会话使配置生效

source /etc/profile.d/python.sh

pip install --upgrade pip
pip install --upgrade setuptools
pip install virtualenv

ln -s /usr/local/python3/bin/virtualenv /usr/bin/virtualenv
cd /home/
virtualenv --python=/usr/bin/python test_env
virtualenv test_env(也一样是python3，之前已经修改了默认Python版本)
source test_env/bin/activate

进入虚拟环境安装各个软件

pip install Django==3.0.2 
pip install uwsgi
ln -s /usr/local/python3/bin/uwsgi /usr/bin/uwsgi
pip install pillow
pip install django-mdeditor
pip install Markdown

特别的，安装mysqlclient需要系统安装过mysql-devel，不然报错

yum -y install mysql-devel

pip install mysqlclient
