為了安裝runlike 更新python2至python3

1.安裝依賴

yum install openssl-devel zlib-devel readline-devel sqlite-devel gcc -y

2.下載下傳并編譯安裝

2.1 下載下傳

wget https://www.python.org/ftp/python/3.10.0/Python-3.10.0.tgz

2.2解壓

tar zxvf Python-3.10.0.tgz

2.3移動到/usr/local

mv Python-3.10.0 /usr/local/python3

2.4進到目錄

cd /usr/local/python3

2.5編譯安裝

./configure --enable-shared --enable-loadable-sqlite-extensions \

--prefix=/usr/local/python3 --with-zlib --with-ssl

make && make install

3.備份舊的版本，然後更新

3.1這一步就是常說的替換原來的指令

cd /usr/bin

mv python python2.7.5

3.2替換為新的版本指令

ln -s /usr/local/python3/bin/python3.7 /usr/bin/python

4.添加python到動态庫

echo "/usr/local/python3/lib" >> /etc/ld.so.conf

#使新添加的路徑生效

ldconfig

#檢視版本

python --version

Python 3.10.0

5.修改yum配置檔案，python更新這是必要要做的

vim /usr/bin/yum

#第一行修改為：

#!/usr/bin/python2.7.5

:wq

6.安裝pip

https://bootstrap.pypa.io/pip/3.5/

wget https://bootstrap.pypa.io/pip/3.5/get-pip.py

python get-pip.py

ln -s /usr/local/python3/bin/pip3.10 /usr/bin/pip
