Centos7源码升级python3.10

说明

由于openssl不提供1.X版本,只提供3.x版本,现以openssl3.0+nginx1.26源码安装

实施

安装依赖依赖

yum -y groupinstall "Development tools"
yum install gcc openssl-devel bzip2-devel libffi-devel perl-IPC-Cmd

下载 openssl 源码包

wget https://www.openssl.org/source/openssl-3.0.13.tar.gz
tar -zxf openssl-3.0.13.tar.gz
pushd openssl-3.0.13 > /dev/null

编译 openssl 安装

./config --prefix=/usr/local/openssl shared zlib
cpu_num=`cat /proc/stat | grep cpu[0-9] -c`
make -j${cpu_num} && make install

备份老 openssl

mv /usr/bin/openssl /usr/bin/openssl.oldbak
mv /usr/include/openssl /usr/include/openssl.oldbak

创建 openssl 软链接

ln -sf /usr/local/openssl/bin/openssl /usr/bin/openssl
ln -sf /usr/local/openssl/include/openssl /usr/include/openssl
ln -sf /usr/local/openssl/lib64/libssl.so.3 /usr/lib64/libssl.so.3
ln -sf /usr/local/openssl/lib64/libcrypto.so.3 /usr/lib64/libcrypto.so.3

更新加载动态连接库数据

#openssl放弃了32位，默认采用64位

echo /usr/local/openssl/lib64 >> /etc/ld.so.conf
ldconfig -v

检查 openssl 版本

openssl version
popd > /dev/null
rm -rf openssl-3.0.13

下载 Python3 源码包

wget https://www.python.org/ftp/python/3.10.14/Python-3.10.14.tgz
tar -zxf Python-3.10.14.tgz
pushd Python-3.10.14 > /dev/null

编译安装

编译完成指定安装到/usr/local/python3

./configure --prefix=/usr/local/python3 --with-openssl=/usr/local/openssl --with-ensurepip=yes CFLAGS="-I/usr/local/openssl/include" LDFLAGS="-L/usr/local/openssl/lib64"
cpu_num=`cat /proc/stat | grep cpu[0-9] -c`
make -j${cpu_num} && make install

添加环境变量

echo "export PATH=/usr/local/python3/bin:$PATH" >> /etc/profile
source /etc/profile

创建 python3 软链接

ln -sf /usr/local/python3/bin/python3.10 /usr/bin/python3
ln -sf /usr/local/python3/bin/pip3.10 /usr/bin/pip3

检查 Python 版本

python3 --version
pip3 --version
popd > /dev/null
rm -rf Python-3.10*
