ubuntu 安装 Ollama

1. 下载优化（使用国内镜像源）

sudo curl -L https://gh-proxy.com/https://github.com/ollama/ollama/releases/download/v0.5.11/ollama-linux-amd64.tgz -o /usr/local/ollama-linux-amd64.tgz

cd /usr/local/
sudo tar -zxvf ollama-linux-amd64.tgz -C /usr/local/

2. 设置权限

sudo chmod +x /usr/local/bin/ollama
