Installing ollama on Rocky 9.x

To install Ollama on local system use following steps:

Install ollama directly from site using:
```
curl -fsSL https://ollama.com/install.sh | sh
```
We can also install specific version of ollama using syntax similar to below example:
curl -fsSL https://ollama.com/install.sh | OLLAMA_VERSION=0.5.7 sh
For this look at model release versions at https://github.com/ollama/ollama/releases
Check whether ollama service is running via:
```
systemctl status ollama
```
After this run ollama on local system via below commands and test:
```
ollama run deepseek-r1:1.5b
```
The above command may take considerable time when run for first time as it download the entire model. deepseek-r1:1.5b model in above example is 1.1GB in size. So first the command will download 1.1GB model and only after that we can prompt ">>>" to type our queries.
The ollama service runs as ollama user with home folder as /usr/share/ollama. Consider moving /usr/share/ollama to partition with more space and create symoblic link at the original place.
Edit /etc/systemd/system/ollama.service and append one more Environment condition
```
Environment="OLLAMA_HOST=0.0.0.0"
```
Restart service
```
systemctl daemon-reload
systemctl restart ollama
```
Without above we cannot use Ollama from n8n etc. over http://localhost:11434/
To close the system use:
```
/bye
```
Between any two queries which are unrelated we can clear the context using:

/clear
