為了安裝runlike 升級python2至python3

1.安裝依賴

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

2.下載並編譯安裝
2.1 下載
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，然后升級
3.1這一步就是常說的替換原來的命令

cd /usr/bin
mv python python2.7.5

3.2替換為新的版本命令
ln -s /usr/local/python3/bin/python3.7 /usr/bin/python

4.添加python到動態庫
echo "/usr/local/python3/lib" >> /etc/ld.so.conf

#使新添加的路徑生效
ldconfig

#查看版本

python --version
Python 3.10.0

5.修改yum配置文件，python升級這是必要要做的
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
==================================================

pip install runlike
cp /usr/local/python3/bin/runlike /usr/bin

runlike -p contain_name
