1. centos7.6 安装python3需要升级openssl

[root@ftp ~]# curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo[root@ftp ~]# yum install -y ncurses-devel gdbm-devel xz-devel sqlite-devel tk-devel uuid-devel readline-devel bzip2-devel libffi-devel[root@ftp ~]# yum install -y openssl-devel openssl11 openssl11-devel[root@ftp ~]# openssl11 version

2. 安装python3

python下载地址：https://www.python.org/ftp/python/

[root@ftp ]# mkdir -p /doc/temp && cd /doc/temp
[root@ftp temp]# wget https://www.python.org/ftp/python/3.10.14/Python-3.10.14.tgz#注意：编译时需要使用最新openssl库
[root@ftp Python-3.10.14]# export CFLAGS=$(pkg-config --cflags openssl11)
[root@ftp Python-3.10.14]# export LDFLAGS=$(pkg-config --libs openssl11)#验证是否生效
[root@ftp Python-3.10.14]# echo $CFLAGS
-I/usr/include/openssl11
[root@ftp Python-3.10.14]# echo $LDFLAGS
-L/usr/lib64/openssl11 -lssl -lcrypto[root@ftp temp]# tar xf Python-3.10.14.tgz
[root@ftp temp]# cd Python-3.10.14#编译
[root@ftp Python-3.10.14]# ./configure --enable-optimizations && make altinstall#配置软连接
[root@ftp Python-3.10.14]# ln -sf /usr/local/bin/python3.10 /usr/bin/python3
[root@ftp Python-3.10.14]# ln -sf /usr/local/bin/pip3.10 /usr/bin/pip3

3. 查看python3版本

[root@ftp Python-3.10.14]# python3 --version
