## Ansible Logging
Ansible playbook executions are automatically logged to a file called `playbook-execution.log` in the root directory of the project. The path to this log file can be changed by editing `ansible.cfg` in the project root directory and specifying a different path.

## Troubleshooting
Ansible has a built in debug output. Simple run Ansible with a `-v`. There are 5 levels of debug output and they are denoted by the number of v's listed. Each level up provide more debug output than the level before it.

Level 1: `-v`

Level 2: `-vv`

Level 3: `-vvv`

Level 4: `-vvvv`

Level 5: `-vvvvv`

Example execution with level 3 debug output: `ansible-playbook -i inventory.yml site.yml -vvv`

To use MariaDB Galera cluster, run on one SQL cluster node:

```
CREATE DATABASE gitea CHARACTER SET utf8 COLLATE utf8_general_ci;

CREATE USER 'gitea'@'10.42.1.163' IDENTIFIED BY 'password';

GRANT ALL PRIVILEGES ON gitea.* TO 'gitea'@'10.42.1.163';

FLUSH PRIVILEGES;
 ```

Disable IPv6 in nginx. Comment out this line in /etc/nginx/sites-enabled/default.conf :
listen [::]:80 default_server;
