升级sqlite3

由于centos7默认sqlite3版本比较低,启动项目会因为sqlite3版本过低无法启动

• 检查sqlite3默认版本

• 下载高版本sqlite3

wget --no-check-certificate  https://www.sqlite.org/2019/sqlite-autoconf-3270200.tar.gz

• 解压

tar xf sqlite-autoconf-3270200.tar.gz

• 编译安装

cd sqlite-autoconf-3270200
./configure --prefix=/usr/local
make && make install

• 替换旧版本sqlite3

mv /usr/bin/sqlite3  /usr/bin/sqlite3_old
ln -s /usr/local/bin/sqlite3   /usr/bin/sqlite3

• 设置开机自动加载

vim  ~/.bashrc
export LD_LIBRARY_PATH="/usr/local/lib"  #增加

• 重启服务器

reboot

安装Python3

• 安装依赖包

yum -y groupinstall "Development tools"
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 libffi-devel -y

• 下载python3 压缩包

wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tar.x

• 编译安装

mkdir /usr/local/python3
tar xf Python-3.7.0.tar.xz
cd Python-3.7.0
./configure --prefix=/usr/local/python3
make && make install
ln -s /usr/local/python3/bin/python3 /usr/local/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip3

创建虚拟环境

#安装virtualenv
pip3 install virtualenv -i https://mirrors.aliyun.com/pypi/simple/
ln -s /usr/local/python3/bin/virtualenv /usr/bin/virtualenv
#创建虚拟目录
[root@k8s-node02 ~]# virtualenv web
#切换到虚拟环境
[root@k8s-node02 ~]# source web/bin/activate

在虚拟环境中安装ipython

(web) [root@k8s-node02 ~]# pip install ipython -i https://mirrors.aliyun.com/pypi/simple/

在虚拟环境中安装django

• 查看安装列表

• 安装django3

(web) [root@k8s-node02 ~]# pip install django -i https://mirrors.aliyun.com/pypi/simple/

创建项目(工程)

(web) [root@k8s-node02 ~]# django-admin startproject myweb

运行项目

访问项目

修改settings.py配置文件

ALLOWED_HOSTS = ["*"]

再次访问:

创建cmdb应用

(web) [root@k8s-node02 myweb]# django-admin startapp cmdb

生成迁移文件

(web) [root@k8s-node02 myweb]# python manage.py migrate
