1、下载地址 Download Ollama on Linux

2、有网络直接执行 curl -fsSL https://ollama.com/install.sh | sh 命令

3、下载慢的解决方法 

1、curl -fsSL https://ollama.com/install.sh -o ollama_install.sh
2、sed -i 's|https://ollama.com/download/ollama-linux|https://gh.llkk.cc/https://github.com/ollama/ollama/releases/download/v0.5.7/ollama-linux|g' ollama_install.sh
3、chmod +x ollama_install.sh
4、sh ollama_install.sh

4、修改端口和模型路径

 vim /etc/systemd/system/ollama.service

     这个是增加的变量

     "OLLAMA_MODELS=/mnt/ollama/models"       "OLLAMA_HOST=0.0.0.0:1001

[Unit]
Description=Ollama Service
After=network-online.target[Service]
ExecStart=/usr/local/bin/ollama serve
User=ollama

Environment="PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/dat/java/jdk1.8.0_271/bin:/dat/java/jdk1.8.0_271/jre/bin:/root/bin" "OLLAMA_MODELS=/mnt/ollama/models" "OLLAMA_HOST=0.0.0.0:1001"[Install]
WantedBy=default.target

文件夹赋权限

1、 chomd 775 -R /mnt/ollama/models/
2、 chown ollama.ollama -R /mnt/ollama/models

保存之后执行，重载和重启命令

1、sudo systemctl daemon-reload
2、sudo systemctl restart ollama

4、查看状态启动成功

5、运行模型一定要用这个... 指定端口，因为改了端口。客户端找不到默认了，就会提示

could not connect to ollama app, is it running?（坑了好长一会...）
