CentOS7使用uv安装Python3.11.9的生产级方案

# 执行uv官方安装脚本
curl -LsSf https://astral.sh/uv/install.sh | sh
# 加载环境变量
source $HOME/.local/bin/env
# 建立全局软链接，所有终端可直接调用uv
ln -sf /root/.local/bin/uv /usr/local/bin/uv
ln -sf /root/.local/bin/uvx /usr/local/bin/uvx
# 验证uv
uv --version

# 安装指定版本Python
uv python install 3.11.9
# 查看本地已管理的Python列表
uv python list

# 获取3.11.9解释器路径
PY311_PATH=$(uv python find 3.11.9)
echo $PY311_PATH
# 创建软链接
ln -sf $PY311_PATH /usr/local/bin/python3.11
ln -sf $(dirname $PY311_PATH)/pip3.11 /usr/local/bin/pip3.11
# 版本校验
python3.11 --version
pip3.11 --version
# 校验ssl模块（生产必检，确认pip可正常访问https源）
python3.11 -c "import ssl; print(ssl.OPENSSL_VERSION)"

cat > /etc/profile.d/uv.sh <<'EOF'
export PATH="/root/.local/bin:$PATH"
EOF
chmod +x /etc/profile.d/uv.sh
source /etc/profile.d/uv.sh

mkdir -p /root/.config/uv
cat > /root/.config/uv/uv.toml <<'EOF'
[[index]]
url = "https://pypi.tuna.tsinghua.edu.cn/simple"
default = true
EOF

# 进入业务目录
cd /opt/myapp
# 基于3.11.9创建虚拟环境
uv venv --python 3.11.9 .venv
# 激活虚拟环境
source .venv/bin/activate
# 在虚拟环境内安装依赖
uv pip install 包名

deactivate

# 卸载uv管理的python3.11.9
uv python uninstall 3.11.9
# 删除软链接
rm -f /usr/local/bin/python3.11
rm -f /usr/local/bin/pip3.11
rm -f /usr/local/bin/uv
rm -f /usr/local/bin/uvx
# 删除uv程序、环境配置
rm -rf /root/.local/bin/uv /root/.local/bin/uvx
rm -f /etc/profile.d/uv.sh
rm -rf /root/.local/share/uv
