先进行升级:
yum update -y ;
yum install -y epel-release yum-utils;
yum install -y http://rpms.remirepo.net/enterprise/remi-release-7.rpm;
yum-config-manager --enable remi;
yum install -y centos-release-scl;yum list | grep python3; #发现是python3.6.8
yum install -y python3.x86_64;
# python3.x86_64 0:3.6.8-19.el7_9

接下来安装Anaconda3,这里面包含了丰富的python版本.
curl -k -LO https://repo.anaconda.com/archive/Anaconda3-2020.07-Linux-x86_64.sh;
bash Anaconda3-2020.07-Linux-x86_64.sh;或者后台下载运行:
yum install -y screen ;
screen -dmS upx;
screen -r upx -p 0 -X stuff "cd /tmp;curl -k -LO https://repo.anaconda.com/archive/Anaconda3-2020.07-Linux-x86_64.sh;bash Anaconda3-2020.07-Linux-x86_64.sh;";
screen -r upx -p 0 -X stuff $'\n';
安装完毕后重新登录,PATH变量新加了:
/root/anaconda3/bin:/root/anaconda3/condabin:
# find /root/anaconda3 -name "*python*"; #太多了conda search "^python$";
# 显示很多的python版本输入python后按tab自动补全,发现自动有python3.8

这样就有了python3.8.
/root/anaconda3/bin/python3.8 -m pip list
/root/anaconda3/bin/python3.8 -m pip install -i http://pypi.douban.com/simple --trusted-host pypi.douban.com websocket-client;
接下来安装jdk :
java version "1.8.0_371"
(base) [root@bp-centos-0 tmp]# java -version
java version "1.8.0_371"
Java(TM) SE Runtime Environment (build 1.8.0_371-b11)
