screen 安装包下载：

wget -c https://ftp.gnu.org/gnu/screen/screen-4.8.0.tar.gz

解压文件

tar -xzvf screen-4.8.0.tar.gz 

#新建/home/ysj/Install目录
mkdir Install
#进入安装包目录
cd screen-4.8.0/
#在安装包目录下，新建build目录
mkdir build && cd build
#编译源码，因为没有管理员权限所以在configure后面添加home下自己新建的install路径
../configure -prefix=/home/ysj/Install#
#最后make
make && make install

#在.bashrc文件里设置screen执行路径
vi ~/.bashrc
#添加install路径
PATH=/home/ysj/install/bin:$PATH
