获取sudo权限

ubuntu@VM-0-17-ubuntu:/home/zjc/GUROBI/gurobi911/linux64$ sudo visudo 
# 修改visudo文件
# 添加自己的用户信息，如下  user     ALL=(ALL:ALL) ALL   
# user是你的用户名

#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.
#
Defaults        env_reset
Defaults        mail_badpass
Defaults        secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin"

# Host alias specification

# User alias specification

# Cmnd alias specification

# User privilege specification
root    ALL=(ALL:ALL) ALL
user     ALL=(ALL:ALL) ALL

# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

# Allow members of group sudo to execute any command
%sudo   ALL=(ALL:ALL) ALL

# See sudoers(5) for more information on "#include" directives:

#includedir /etc/sudoers.d
ubuntu  ALL=(ALL:ALL) NOPASSWD: ALL

gurobi下载与安装

官网下载安装包：https://www.gurobi.com/downloads/gurobi-software/

选择想要的版本。

user@VM-0-17-ubuntu:~/GUROBI$ tar -xzvf gurobi9.1.1_linux64.tar.gz

user@VM-0-17-ubuntu:~/GUROBI$ cd ./gurobi911/linux64

user@VM-0-17-ubuntu:~/GUROBI/gurobi911/linux64$ ls
bin  build  docs  EULA.pdf  examples  include  lib  matlab  R  ReleaseNotes.html  setup.py  src
user@VM-0-17-ubuntu:~/GUROBI/gurobi911/linux64$ sudo python setup.py install
[sudo] password for user:

running build
running build_py
running install_lib

removing /home/zjc/GUROBI/gurobi911/linux64/build
user@VM-0-17-ubuntu:~/GUROBI/gurobi911/linux64$ 

添加环境变量

user@VM-0-17-ubuntu:~/GUROBI/gurobi911/linux64$ vim ~/.bashrc

# 修改 ~/.bashrc 文件在文件最后插入 /home/.../为文件路径

export GUROBI_HOME="/home/.../gurobi911/linux64"
export PATH="${PATH}:${GUROBI_HOME}/bin"
export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:${GUROBI_HOME}/lib"

:wq保存

user@VM-0-17-ubuntu:~/GUROBI/gurobi911/linux64$ source ~/.bashrc

激活Gurobi

从Gurobi获取免费的学术 license  一个账号可以申请好多个

user@VM-0-17-ubuntu:~/GUROBI/gurobi911/linux64$ grbgetkey ********-7bd9-11eb-9f6c-************

验证成功后生成gurobi.lic  。 将gurobi.lic的位置/home/....../加入到环境变量里头，

即将下面的指令加入到 ~/.bashrc中，步骤同上。

export GRB_LICENSE_FILE="/home/....../gurobi.lic" 

这里有个小问题，不知道是不是一定要用学校的ipgrbgetkey才行，我在远程 sever上测试不行。（报错如下，估计是我版本下载错了，需要下remote server）

zjc@VM-0-17-ubuntu:~/GUROBI/gurobi911/linux64$ grbgetkey 2669adbc-7bd9-11eb-9f6c-020d093b5256
info  : grbgetkey version , build v9.1.1rc0

zjc@VM-0-17-ubuntu:~/GUROBI/gurobi911/linux64$ 

然后验证是否安装成功：gurobi.sh

user@laptap:~$ gurobi.sh
