python3.0安装

python链接

在 CentOS 7 中安装 Python 依赖

$ yum -y groupinstall development 
$ yum -y install zlib-devel 
$ yum install -y python3-devel openssl-devel libxslt-devel libxml2-devel libcurl-devel 
在 Debian 中，我们需要安装 gcc、make 和 zlib 压缩/解压缩库

$ aptitude -y install gcc make zlib1g-dev
运行下面的命令来安装 Python 3.6：

$ wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tar.xz
$ xz -d  Python-3.6.3.tar.xz
$ tar xvf Python-3.6.3.tar
$ cd Python-3.6.3/
$ ./configure
$ make && make install

# 查看安装
$ python3 -V
pip3安装

yum groupinstall "Development Toos" -y
yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel -y
wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz
tar -xzvf Python-3.6.0.tgz -C  /tmp
cd  /tmp/Python-3.6.0/
./configure --prefix=/usr/local/python
echo PATH='/usr/local/python/bin/:$PATH' >> /etc/profile
source /etc/profile

yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel -y
yum -y install gcc make python-devel libffi-devel
wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz
tar -xzvf Python-3.6.0.tgz -C  /tmp
cd  /tmp/Python-3.6.0/
./configure && make && make install
python -V

进入到project目录，进入到Shell模式直接修改

python manage.py shell
from django.contrib.auth.models import User  
user =User.objects.get(username='admin') 
user.set_password('new_password')  
user.save()

如果超级用户也忘记了，尝试以下方式获取superuser
from django.contrib.auth.models import User
user1 = User.objects.filter(is_superuser = True)
user2 = User.objects.filter(is_superuser = True, is_staff = True) 
print user1, user2
