- 查看当前openssl的版本信息
[root@hadoop100 ~]# openssl version
OpenSSL 1.0.2k-fips 26 Jan 2017
需要升级
REF: https://github.com/stardock/openlssl3.2
虚拟机默认实验sudo yum -y python3是会报错的,因为的库没有。所以我们可以安装epel扩展软件包
sudo yum -y install epel-release 本文用编译安装所以这里用不上
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel libffi-devel gdbm-devel db4-devel libpcap-devel xz-devel make
[rootg@hadoop100 ~]$ wget https://www.python.org/ftp/python/3.10.14/Python-3.10.14.tgz
[rootg@hadoop100 ~]$ tar -xvzf Python-3.10.14.tgz
[rootg@hadoop100 ~]$ cd Python-3.10.14/
1):在Python3.7之后的版本,依赖的openssl,必须要是1.1或者1.0.2之后的版本,或者安装了2.6.4之后的libressl,linux自带的openssl版本过低。
2):在编译之后修改Modules/Setup文件中的部分内容,打开ssl,或者在编译的时候指定–with-ssl参数(我使用的是前面的方式,后一种方式的真实性有待考究)
- 修改 vim ../Python-3.10.14/Modules/Setup
shift+g 跳转到末尾 然后在末尾粘贴如下内容,wq保存退出
_socket socketmodule.c
# Socket module helper for SSL support; you must comment out the other
# socket line above, and possibly edit the SSL variable:
SSL=/usr/local/openssl3.2
_ssl _ssl.c \
-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
-L$(SSL)/lib -lssl -lcrypto
cd ../Python-3.10.14
- 指定编译语言(可选)
export LANG=zh_CN.UTF-8
export LANGUAGE=zh_CN.UTF-8
- 指定安装目录
./configure --prefix=/usr/local/python3.10 --with-ssl=/usr/local/openssl3.2
或(主要看/usr/local/openssl是否存在) - 编译安装
make
make install
make clean
- 安装完python后,切换到安装的bin目录,检查ssl功能是否正常
cd /usr/local/python3.10/bin
./python3
import ssl
exit() #退出python3解释器后执行查看./pip3 list
./pip3 list
ln -s /usr/local/python3.10/bin/python3.10 /usr/bin/python3.10
ln -s /usr/local/python3.10/bin/pip3.10 /usr/bin/pip3.10
ln -s /usr/local/python3.10/bin/python3.10 /usr/bin/python3
ln -s /usr/local/python3.10/bin/pip3.10 /usr/bin/pip3
-
编辑/etc/profile,在尾部添加如下代码:
echo 'export PATH=$PATH:/usr/local/python3.10/bin' >> /etc/profile -
使用source命令重新加载/etc/profile
source /etc/profile -
查看安装的python版本
python3 --version
