银河麒麟安装Python3.7.4以及升级自带OpenSSL
升级OpenSSL
1.下载opensslwget https://www.openssl.org/source/openssl-1.1.1a.tar.gz
tar -zxvf openssl-1.1.1a.tar.gz
cd openssl-1.1.1a
2.编译安装./config --prefix=/usr/local/openssl no-zlib #不需要zlib
make
make install
3.备份原配置mv /usr/bin/openssl /usr/bin/openssl.bak
mv /usr/include/openssl/ /usr/include/openssl.bak
4.新版配置ln -s /usr/local/openssl/include/openssl /usr/include/openssl
ln -s /usr/local/openssl/lib/libssl.so.1.1 /usr/local/lib64/libssl.so
# 这里可能会提示路径不存在，可以直接创建
ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
5.写入openssl库文件的搜索路径echo "/usr/local/openssl/lib" >> /etc/ld.so.conf
6.使修改后的/etc/ld.so.conf生效ldconfig -v
7.查看openssl版本openssl version
安装python3.7.4# 下载源码包并解压
cd ~
wget https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tar.xz
sudo apt-get install gcc libffi-devel zlib* openssl-devel
xz -d Python-3.7.4.tar.xz
tar xvf Python-3.7.4.tar
# 设置路径和安装
cd Python-3.7.4
./configure --prefix=/usr/local/python3 --with-openssl=/usr/local/openssl
make
make install
软连接sudo ln -s /usr/local/python3.7/bin/python3 /usr/bin/python3.7
查看结果python3.7 -V
# 显示结果为： Python 3.7.4
安装python3.7.4成功，同时。系统中的python2和python3.5.2也存在
安装pip3.7sudo ln -s /usr/local/python3.7/bin/pip3.7 /usr/bin/pip3.7
测试：pip3.7 install dicttoxml
更新pip至最新版本：sudo python3.7 -m pip3.7 install --upgrade pip
pip3.7 -V # 查看pip版本
