linux修改Ollama默认模型保存路径

比如：/data/ollama/models 该文件普通用户可能没有权限修改;需给当前用户赋予权限：

sudo chown -R ec2-user:ec2-user /data/ollama/models

1、修改启动配置文件/etc/systemd/system/ollama.service,将目标目录添加到此

sudo vim /etc/systemd/system/ollama.service

新增这一行Environment="OLLAMA_MODELS=/data/ollama/models"

其中/data/ollama/models该目录是你要配置的目标模型存放目录

修改后：

[Unit]
Description=Ollama Service
After=network-online.target

[Service]
ExecStart=/usr/local/bin/ollama serve
User=ollama
Group=ollama
Restart=always
RestartSec=3
Environment="PATH=/home/ec2-user/.local/bin:/home/ec2-user/miniconda3/condabin:/usr/local/jdk11/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin"
Environment="OLLAMA_MODELS=/data/ollama/models"
[Install]
WantedBy=default.target

2、加载配置

sudo systemctl daemon-reload

3、重启Ollama服务

 sudo systemctl restart ollama

4、测试修改是否成功拉一个模型看看是否是存放到了修改后的目录

ollama pull phi4
