再纯净的Ubuntu中编译安装petsc

1. docker pull ubuntu
2. docker run -ti ubuntu bash
3. 在新容器里执行命令

apt-get update
apt-get install vim

4. 更换阿里云的源
   deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
   deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
   deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
   deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
   deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse
   deb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse
   deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse
   deb-src http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse
   deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
   deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
5. 安装openmpi

sudo apt-get install openmpi-bin liblapack-dev

6. 下载最新的petsc-3.13.5.zip并解压

unzip petsc-3.13.5.zip

7. 在configure的过程中，我额外安装了make，wget和python3-pip才不会报错

apt-get install make wget python3-pip
python3 configure

8. 最后将容器打包就好啦

docker commit 261314c94305 mypetsc
