MythWeb is a web interface for MythTV

## Installation

Before installing MythWeb, first set up Apache with PHP as described in Apache HTTP Server and Apache HTTP Server#PHP.

Install the mythplugins-mythwebAUR package.

## Configuration

### MythTV integration

MythWeb looks in the `video_dir` directory for MythTV recordings. Create a link to the folder where your MythTV recordings are stored:

    # ln -s recording_dir /var/lib/mythtv/mythweb/video_dir

### MythWeb

Copy the MythWeb configuration file `mythweb.conf` to the Apache HTTP Server configuration directory.

    # cp /var/lib/mythtv/mythweb/mythweb.conf.apache /etc/httpd/conf/extra/mythweb.conf

And include it at the bottom of `/etc/httpd/conf/httpd.conf`:

    Include conf/extra/mythweb.conf

If you want to use MythWeb with the recent default `mythweb.conf` options enabled you will also need to uncomment the following lines in `httpd.conf`:

    LoadModule rewrite_module modules/mod_rewrite.so
    LoadModule deflate_module modules/mod_deflate.so

You will also need to enable CGI uncomment the following lines in `httpd.conf`:

    <IfModule !mpm_prefork_module>
            LoadModule cgid_module modules/mod_cgid.so
    </IfModule>
    <IfModule mpm_prefork_module>
            LoadModule cgi_module modules/mod_cgi.so
    </IfModule>

Edit `mythweb.conf` to point it to the installation directory for mythweb (near the beginning of the file):

    <Directory "/srv/http/mythweb/data">

    <Directory "/srv/http/mythweb" >

Then check that the configuration matches your MythTV setup. If you have changed the database login or password, you will need to change the following section. Double-check the following lines are uncommented in any case:

    setenv db_server        "localhost"
    setenv db_name          "mythconverg"
    setenv db_login         "mythtv"
    setenv db_password      "mythtv"

### PHP

Edit the PHP configuration file `/etc/php/php.ini`

Uncomment the following lines in the Dynamic extensions section.

    extension=mysqli

Make sure `open_basedir` contains `/srv/http/` and `/var/lib/mythtv/mythweb` to allow file operation in the MythWeb directory. Starting with MythTV 0.23, you will also need to permit access to `/usr/share/mythtv/`.

    open_basedir = /srv/http/:/home/:/tmp/:/usr/share/pear/:/var/lib/mythtv/mythweb:/usr/share/mythtv/

Enable the `allow_url_fopen` option for MythWeb's status page to work.

    allow_url_fopen = On

## Set rights for mythtv dir and create the link to mythweb

    chmod 755 -R /var/lib/mythtv/

    ln -s /var/lib/mythtv/mythweb /srv/http/

## Using MythWeb

You can now start the Apache daemon by starting the `httpd.service` systemd unit. mythbackend must already be running.

Open MythWeb in your browser.

    http://localhost/mythweb

## Securing MythWeb

It is also probably a good idea to set up password protection for MythWeb, if you intend to allow connections from the Internet. To enable authentication uncomment the authentication section (near the beginning):

    /etc/httpd/conf/extra/mythweb.conf

    AuthType           Digest
    AuthName           "MythTV"
    AuthUserFile       /var/www/htdigest
    Require            valid-user
    BrowserMatch       "MSIE"      AuthDigestEnableQueryStringHack=On
    Order              allow,deny
    Satisfy            any

Now, we need to fix the configuration to match the MythWeb set up, change the `AuthUserFile` to

    AuthUserFile       /etc/httpd/conf/extra/httpd-passwords

If you do not want to access MythWeb from IE, you can delete the BrowserMatch line.

You also probably do not want to have to enter your password when you are connecting from your local computer, so add the following line between the last two lines:

    Allow from 127. 192.168.1.

This will cause passwordless access from both your local machine and your local network (provided you are using the 192.168.1.0 255.255.255.0 subnet)

The configuration should now look something like:

    AuthType           Digest
    AuthName           "MythTV"
    AuthUserFile       /etc/httpd/conf/extra/httpd-passwords
    Require            valid-user
    Order              allow,deny
    Allow from 127. 192.168.1.
    Satisfy            any

Save the file.

Next, we will create the `httpd-passwords` file

    # htdigest -c /etc/httpd/conf/extra/httpd-passwords MythTV myuser

Where myuser is the username you want to use to access MythWeb. Enter the login password when prompted.

If you need more users, omit `-c` - otherwise you will overwrite the current file:

    # htdigest /etc/httpd/conf/extra/httpd-passwords MythTV myuser2

Now all we need to do now is restart apache's `httpd.service` for the changes to take effect.

## Troubleshooting

If you get a 403 Forbidden error, recheck your paths in `mythweb.conf`

If you can not start the apache service, and you get and error like this:

    # journalctl -u httpd -xn
    ...
    AH00013: Pre-configuration failed
    ...

Comment out the following line in `httpd.conf`:

    LoadModule mpm_event_module modules/mod_mpm_event.so

and use the prefork module instead:

    LoadModule mpm_prefork_module modules/mod_mpm_prefork.so
