Linux环境下Ollama安装报错： Error: xxx: permission denied

使用命令sudo chown -R ollama:ollama /usr/share/ollama
如果不行的话试下下面的：

情形1

Nov 26 21:30:04 gpuserver ollama[4092300]: Couldn't find '/usr/share/ollama/.ollama/id_ed25519'. Generating new private ke>
Nov 26 21:30:04 gpuserver ollama[4092300]: Error: open /usr/share/ollama/.ollama/id_ed25519: permission denied
Nov 26 21:30:04 gpuserver systemd[1]: ollama.service: Main process exited, code=exited, status=1/FAILURE
Nov 26 21:30:04 gpuserver systemd[1]: ollama.service: Failed with result 'exit-code'.

1. 使用命令ssh-keygen -t rsa -b 4096 -C "my.email@gmail.com"创建一个id_ed25519和id_ed25519.pub文件
2. 复制到/usr/share/ollama/.ollama/路径下：

   sudo cp /home/user/.ssh/id_ed25519 /usr/share/ollama/.ollama/
   sudo cp /home/user/.ssh/id_ed25519.pub /usr/share/ollama/.ollama/
   

3. 赋权

   sudo chmod a+x /home/user/.ssh/id_ed25519
   sudo chmod a+x /home/user/.ssh/id_ed25519.pub
   

情形2

Nov 26 21:32:32 gpuserver ollama[4094351]: Error: mkdir /usr/share/ollama/.ollama/models: permission denied
Nov 26 21:32:32 gpuserver systemd[1]: ollama.service: Main process exited, code=exited, status=1/FAILURE
Nov 26 21:32:32 gpuserver systemd[1]: ollama.service: Failed with result 'exit-code'.

1. 使用命令sudo mkdir /usr/share/ollama/.ollama/models创建该文件夹
2. 同样赋权sudo chmod a+x /usr/share/ollama/.ollama/models

检验

1. sudo systemctl start ollama
2. journalctl -e -u ollama
3. 看到Nov 26 21:33:40 gpuserver systemd[1]: Started ollama.service - Ollama Service.说明Ollama启动成功

情形3（拉取模型）

user@gpuserver:~$ ollama run qwen2.5-coder

sudo chown -R ollama:ollama /usr/share/ollama
修改前

修改后

好像也可以选择更改模型保存位置
