centos7安装Python3.10.4最新稳定版

        服务环境：centos7 安装Python3.10.4最新稳定版，以下为安装过程 *** 作。

Python各个版本路径：

python所有版本https://www.python.org/ftp/python/

Python3.10.4下各版本

https://www.python.org/ftp/python/3.10.4/https://www.python.org/ftp/python/3.10.4/

下载python最新稳定版
wget https://www.python.org/ftp/python/3.10.4/Python-3.10.4.tgz

安装依赖环境
yum -y groupinstall "Development tools"
yum install -y ncurses-devel gdbm-devel xz-devel sqlite-devel tk-devel uuid-devel readline-devel bzip2-devel libffi-devel
yum install -y openssl-devel openssl11 openssl11-devel  #删除

解压文件，并进入安装目录
tar -zxvf Python-3.10.4.tgz
cd Python-3.10.4

编译安装
./configure --enable-optimizations && make altinstall

验证安装结果
/usr/local/bin/python3.10 --version
/usr/local/bin/pip3.10 --version

官方的pip源无法访问，以下错误显示，需要手动配置pip源

Could not fetch URL https://pypi.org/simple/pip/: There was a problem
confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443):
Max retries exceeded with url: /simple/pip/ (Caused by SSLError(SSLCertVerificationError(1,
'[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer
certificate (_ssl.c:997)')))

新建pip配置文件

mkdir -p ~/.pip
touch ~/.pip/pip.conf

编辑配置文件如下

vim ~/.pip/pip.conf

[global]
index-url=https://pypi.tuna.tsinghua.edu.cn/simple/
extra-index-url=
        http://pypi.douban.com/simple/
        http://mirrors.aliyun.com/pypi/simple/

#proxy = [user:passwd@]proxy.server:port
[install]
trusted-host=
        pypi.tuna.tsinghua.edu.cn
        pypi.douban.com
        mirrors.aliyun.com
ssl_verify: false

以上配置了清华，豆瓣，阿里云源，并且关闭了ssl验证。当然如果有需要还可以设置代理,把注释掉的proxy那行放开即可。

再验证一下

pip3 install --upgrade pip
