OS support

HAProxy-WI was tested on EL7, EL8 and all scripts too. Debian/Ubuntu OS support at 'beta' stage, may work not correct

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';

Settings

Edit $HOME_HAPROXY-WI/app/haproxy-wi.cfg with your env

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

For Runtime API, Metrics and Alerting enable state file and stat socket 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.state
		
    defaults
        load-server-state-from-file global
		
    listen stats 
        bind *:8085
        stats enable
        stats uri /stats
        stats realm HAProxy-04\ Statistics
        stats auth admin:password
        stats admin if TRUE 

Create and update DB

$ cd /var/www/haproxy-wi/app
$ ./create_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
$ ./create_db.py

and check executeble py files

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