CMDB资产管理平台idcops搭建

考虑到IDC多机房，大量资产管理起来比较麻烦，于是便想上平台，在github上看到django-idcops还不错，但是没有详细的安装步骤，于是整理了下搭建过程，以及过程中遇到的问题。

git地址 ：https://github.com/Wenvki/django-idcops

作者博客：https://www.iloxp.com/

环境：

系统：Centos7.6

PY：python3.8.2

文章目录：

　　一、python安装及设置

　　二、环境设置

　　三、拉取git代码

安装过程中遇到的问题参考附录1

一、python安装及设置

1、py安装

wget https://www.python.org/ftp/python/3.8.2/Python-3.8.2.tgz

然后进目录编译安装

mkdir /usr/local/python3

./configure --prefix=/usr/local/python3

make && make install 

2、pip源更换

pip config set global.index-url https://mirrors.aliyun.com/pypi/simple/

pip install --upgrade pip

# 豆瓣
https://pypi.doubanio.com/simple/
# 阿里云
https://mirrors.aliyun.com/pypi/simple/
# 清华大学
https://pypi.tuna.tsinghua.edu.cn/simple/
https://mirrors.tuna.tsinghua.edu.cn/pypi/web/simple/

二、环境设置

添加软链接：

ln -s /usr/local/python3/bin/pip3.8 /usr/bin/pip

ln -s /usr/local/python3/bin/python3.8  /usr/bin/python

修改yum配置

 vi /usr/bin/yum

#!/usr/bin/python" 改为 "#!/usr/bin/python2.7"

 三、拉取git代码

git clone https://gitee.com/wenvki/django-idcops.git idcops
cd idcops/
virtualenv -p /usr/local/python3/bin/python3 env  ###virtualenv安装：pip install virtualenv
source env/bin/activate
pip install -U pip -i https://mirrors.aliyun.com/pypi/simple/ 
pip install -r requirements.txt -i https://mirrors.aliyun.com/pypi/simple/   ###如果出现django版本报错，检查python版本，必须要是python3
python manage.py migrate
python manage.py runserver 0.0.0.0:8000

问题：ModuleNotFoundError: No module named '_sqlite3'

yum安装sqlite3.so的库

yum install sqlite* 

然后重新编译安装 python3

问题：make migrate时出现报错，

把/idcops/idcops/migrations 目录删掉，然后重新 python manage.py migrate

(env) [root@localhost mysite]# python manage.py migrate
