1、卸载已有的python3
#卸载pyhton3 [root@kycxnode111 ~]# rpm -qa|grep python3|xargs rpm -ev --allmatches --nodeps 软件包准备中... python3-libs-3.6.8-13.el7.x86_64 python3-pip-9.0.3-7.el7_7.noarch python3-setuptools-39.2.0-10.el7.noarch python3-3.6.8-13.el7.x86_64 #删除所有残余文件 [root@kycxnode111 ~]# whereis python3 |xargs rm -frv 已删除目录："/usr/lib/python3.6/site-packages/__pycache__" 已删除目录："/usr/lib/python3.6/site-packages" 已删除目录："/usr/lib/python3.6" # 查看目前系统中的python [root@kycxnode111 ~]# whereis python python: /usr/bin/python /usr/bin/python2.7 /usr/bin/python2.7-config /usr/lib/python2.7 /usr/lib64/python2.7 /etc/python /usr/include/python2.7 /usr/share/man/man1/python.1.gz
2、下载安装最新的python
1）、安装依赖包
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc* make -y
[root@kycxnode111 ~]# yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc* make -y 已加载插件：fastestmirror Loading mirror speeds from cached hostfile epel/x86_64/metalink | 6.6 kB 00:00:00 * base: mirror.bit.edu.cn * epel: d2lzkl7pfhq30w.cloudfront.net * extras: mirror.bit.edu.cn * updates: mirrors.aliyun.com base | 3.6 kB 00:00:00 docker-ce-stable | 3.5 kB 00:00:00 epel | 4.7 kB 00:00:00 extras | 2.9 kB 00:00:00 updates | 2.9 kB 00:00:00 (1/3): updates/7/x86_64/primary_db | 4.5 MB 00:00:12 (2/3): epel/x86_64/updateinfo
2、下载python的安装包
wget https://www.python.org/ftp/python/3.8.4/Python-3.8.4.tgz
PS:这里下载python3.8.5 是因为要与后面系统中的Django的稳定性好
3、解压python安装包 并创建python3 的文件夹
tar -xvf Python-3.8.4.tgz
mkdir /usr/local/python3
4、配置安装路径
configure是一个shell脚本，根据平台的特性生成Makefile文件，为下一步的编译做准备。可以通过在 configure 后加上参数来对安装进行控制，比如下面就是指定安装目录/usr/local/python3。如果没有用这个选项，安装过程结束后，该软件所需的软件被复制到不同的系统目录下，比较混乱。
切入到解压目录下
cd Python-3.8.4/
./configure --prefix=/usr/local/python3

"--enable-optimizations"这个参数会启用配置文件引导的优化（PGO）和链接时间优化（LTO）。两者都是昂贵的优化，会减慢构建过程，但会显着提高速度（我记得阅读的内容大约有10-20％）。

5、编译安装
切入到解压目录下
make && make install
发现出现如下错误
查阅资料可知 是在configure 时使用 --enable-optimizations 导致的 看来上面的操作是多此一举了
参考链接：https://bugs.python.org/issue34112
重新执行
./configure --prefix=/usr/local/python3
make && make install
.......... rm -f /usr/local/bin/pydoc3 (cd /usr/local/bin; ln -s pydoc3.8 pydoc3) rm -f /usr/local/bin/2to3 (cd /usr/local/bin; ln -s 2to3-3.8 2to3) if test "x" != "x" ; then rm -f /usr/local/bin/python3-32; (cd /usr/local/bin; ln -s python3.8-32 python3-32) fi rm -f /usr/local/share/man/man1/python3.1 (cd /usr/local/share/man/man1; ln -s python3.8.1 python3.1) if test "xupgrade" != "xno" ; then case upgrade in upgrade) ensurepip="--upgrade" ;; install|*) ensurepip="" ;; esac; ./python -E -m ensurepip $ensurepip --root=/ ; fi Looking in links: /tmp/tmplhwofxk0 Processing /tmp/tmplhwofxk0/setuptools-47.1.0-py3-none-any.whl Processing /tmp/tmplhwofxk0/pip-20.1.1-py2.py3-none-any.whl Installing collected packages: setuptools, pip Successfully installed pip-20.1.1 setuptools-47.1.0
#至此安装结束
6、配置软连接
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ps:因为在创建后有错误在，需要先删除再创建
[root@kycxnode111 bin]#
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln: 无法创建符号链接"/usr/bin/python3": 文件已存在 [root@kycxnode111 bin]# rm -rf /usr/bin/python3
[root@kycxnode111 /]# which pip3 /usr/local/bin/pip3 [root@kycxnode111 /]# pip3 install selenium Collecting selenium Downloading selenium-3.141.0-py2.py3-none-any.whl (904 kB) |████████████████████████████████| 904 kB 98 kB/s Collecting urllib3 Downloading urllib3-1.25.10-py2.py3-none-any.whl (127 kB) |████████████████████████████████| 127 kB 95 kB/s Installing collected packages: urllib3, selenium Successfully installed selenium-3.141.0 urllib3-1.25.10 [root@kycxnode111 /]# type pip3 pip3 已被哈希 (/usr/local/bin/pip3) [root@kycxnode111 /]# hash -r [root@kycxnode111 /]# type pip3 pip3 是 /usr/local/bin/pip3 [root@kycxnode111 /]#
7、为pip3 创建软连接
ln -s /usr/local/python3/bin/python3 /usr/bin/pip3
但是看上面的命令 软链接并没有起到作用，但是pip3 目前可以全局正常使用，具体什么原因导致的目前还暂无定论
至此 python3 和pip3 安装成功
