1、解除安裝已有的python3

#解除安裝pyhton3
[root@kycxnode111 ~]# rpm -qa|grep python3|xargs rpm -ev --allmatches --nodeps 
軟體包準備中...
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

#刪除所有殘餘檔案
[root@kycxnode111 ~]# whereis python3 |xargs
 
 rm -frv
已刪除目錄："/usr/lib/python3.6/site-packages/__pycache__"
已刪除目錄："/usr/lib/python3.6/site-packages"

# 檢視目前系統中的python
[root@kycxnode111 ~]# whereis python

/man1/python.1.gz

2、下載安裝最新的python

1）、安裝依賴包

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

2、下載python的安裝包

wget https://www.python.org/ftp/python/3.8.5/Python-3.8.5.tgz

PS:這裡下載python3.8.5 是因為要與後面系統中的Django的穩定性好

3、解壓python安裝包

tar -xvf Python-3.8.5.tgz

4、配置安裝路徑

切入到解壓目錄下

cd Python-3.8.5/

./configure prefix=/usr/local/python3

  1 [root@kycxnode111 Python-3.8.5]# ls

5、編譯安裝

切入到解壓目錄下

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

#至此編譯結束

6、配置軟連線

ln -s /usr/local/bin/python3 /usr/bin/python3

ps:因為在建立後有錯誤在，需要先刪除再建立

[root@kycxnode111 bin]# ln -s /usr/local/bin/python3 /usr/bin/python3
ln: 無法建立符號連結"/usr/bin/python3": 檔案已存在
[root@kycxnode111 bin]# rm -rf /usr/bin/python3

[root@kycxnode111 /]# which pip3
/usr/local/bin/pip3
[root@kycxnode111 /]# pip3 install selenium

[root@kycxnode111 /]# type pip3
pip3 已被雜湊 (/usr/local/bin/pip3)
[root@kycxnode111 /]# hash -r
[root@kycxnode111 /]# type pip3
pip3 是 /usr/local/bin/pip3
[root@kycxnode111 /]#

7、為pip3 建立軟連線

ln -s /usr/local/bin/pip3 /usr/bin/pip3

但是看上面的命令 軟連結並沒有起到作用，但是pip3 目前可以全域性正常使用，具體什麼原因導致的目前還暫無定論

至此 python3 和pip3 安裝成功
