# Database support

Default Haproxy-WI use Sqlite, if you want use MySQL enable in config, and create database:

### For MySQL support:
```
MariaDB [(none)]> create user 'haproxy-wi'@'%';
MariaDB [(none)]> create database haproxywi;
MariaDB [(none)]> grant all on haproxywi.* to 'haproxy-wi'@'%' IDENTIFIED BY 'haproxy-wi';
MariaDB [(none)]> grant all on haproxywi.* to 'haproxy-wi'@'localhost' IDENTIFIED BY 'haproxy-wi';
```

    global
		stats socket *:1999 level admin 
		stats socket /var/run/haproxy.sock mode 600 level admin

# Update
```
# cd /var/www/haproxy-wi
# chmod +x update.sh
# ./update.sh
```

After update old config saved at /tmp/ folder. Compare new and old config, if in new no changes overwrite the new configuration with the old one, or edit new with your ENV.

# Update DB
```
$ cd /var/www/haproxy-wi/app
$ ./update_db.py
```
# Troubleshooting
If you have error:
```
Forbidden
You don't have permission to access /app/overview.py on this server. 
```

Check owner(must be apache, or another user for apache)

If at first login you have:
```
Internal Server Error
```

Do this:
```
$ cd /var/www/haproxy-wi/app
$ ./update_db.py
```
and check executeble py files

If you see plain text, check section "Directory" in httpd conf
