运行环境：python3>3.7.9、sqlite>v3.7.17

下载安装与部署的要求：

install abidiff (centos): ''' yum install -y epel-release; yum install -y libabigail '''

install createrepo: ''' yum install -y createrepo '''

install binutils: ''' yum install -y binutils '''

注意：openeuler需要配置openEuler-20.03-SP2以上版本everything仓库 install abidiff (openEuler): ''' yum install -y libabigail '''

install oecp: ''' git clone oecp: One for OSV as an certification tool; cd oecp; pip3 install -r requirement '''

本次安装环境：

openEuler20.03

由于自带python3版本为3.7.4，低于oecp工具要求，所以需要先升级Python3版本

1.升级python3

[root@localhost ~]# wget https://www.python.org/ftp/python/3.7.2/Python-3.7.2.tgz
[root@localhost ~]# tar xf Python-3.7.16.tgz
[root@localhost ~]# cd Python-3.7.16
[root@localhost ~]# ./configure prefix=/usr/local/python3.7
[root@localhost ~]# make && make install
[root@localhost ~]# ll /usr/bin/python3
lrwxrwxrwx. 1 root root 9 Mar 24  2020 /usr/bin/python3 -> python3.7
[root@localhost ~]# ll /usr/bin/python3.7
-rwxr-xr-x. 2 root root 15K Mar 24  2020 /usr/bin/python3.7
[root@localhost ~]# python3 -V
Python 3.7.4
[root@localhost ~]# rm -f /usr/bin/python3
[root@localhost ~]# rm -f /usr/bin/pip3
[root@localhost ~]# ln -s /usr/local/python3.7/bin/python3.7 /usr/bin/python3
[root@localhost ~]# ln -s /usr/local/python3.7/bin/pip3.7 /usr/bin/pip3
[root@localhost ~]# python3 -V
Python 3.7.16
升级完成。

2.修改pip源为国内并更新版本

[root@localhost ~]# mkdir ~/.pip
[root@localhost ~]# cd ~/.pip
[root@localhost ~]# vi pip.conf
[global]
index-url=http://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host=mirrors.aliyun.com
[root@localhost oecp]# pip install --upgrade pip
WARNING: Running pip install with root privileges is generally not a good idea. Try `pip install --user` instead.

3.下载oecp并安装

[root@localhost oecp]# cd /root/oecp/
[root@localhost oecp]# pip3 install -r requirement

4.运行oecp脚本检测ISO

注意：内存需要大于2G，磁盘空间也要预留够，否则运行脚本会提示内存或磁盘空间不足。

[root@localhost ~]# python3 cli.py -w /root/diff /root/CentOS-7-x86_64-DVD-2009.iso /root/openEuler-20.03-LTS-x86_64-dvd.iso

运行完成后，会提示文件存放地址
