# Install
The installer will ask you a few questions
```
$ git clone https://github.com/Aidaho12/haproxy-wi.git /var/www/haproxy-wi
$ cd /var/www/haproxy-wi
$ chmod +x install.sh
$ ./install
```
## Manual install
For install just clone:
```
$ cd /var/www/
$ git clone https://github.com/Aidaho12/haproxy-wi.git /var/www/haproxy-wi
$ chown -R apache:apache haproxy-wi/
$ pip install -r haproxy-wi/requirements.txt 
$ chmod +x haproxy-wi/cgi-bin/*.py 
```

For Apache do virtualhost with cgi-bin. Like this:
```
# vi /etc/httpd/conf.d/haproxy-wi.conf 
<VirtualHost *:8080>
        ServerName haproxy-wi
        ErrorLog /var/log/httpd/haproxy-wi.error.log
        CustomLog /var/log/httpd/haproxy-wi.access.log combined

        DocumentRoot /var/www/haproxy-wi
        ScriptAlias /cgi-bin/ "/var/www/haproxy-wi/cgi-bin/"

        <Directory /var/www/haproxy-wi>
                Options +ExecCGI
                AddHandler cgi-script .py
                Order deny,allow
                Allow from all
        </Directory>
</VirtualHost>

# 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';
```

Edit $HOME_HAPROXY-WI/cgi-bin/haproxy-webintarface.config with your env
```
Copy ssh key on all HAproxy servers

Login http://haproxy-wi-server/users.py, and add: users, groups and servers. Default: admin/admin

![alt text](image/haproxy-wi-admin-area.jpeg "Admin area")

For Runtime API enable state file on HAproxt servers and need install socat on all haproxy servers, and configre HAProxy:
```
    global
		stats socket *:1999 level admin 
		stats socket /var/run/haproxy.sock mode 600 level admin
		server-state-file /etc/haproxy/haproxy/haproxy.state
    defaults
		load-server-state-from-file global
   ```

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