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-mythweb package.

Link to the Video Directory

MythWeb looks in the video_dir directory for MythTV recordings. You will need to create a link to the folder where your MythTV recordings are stored.

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

Configuration

MythWeb

Copy the MythWeb configuration file mythweb.conf to the Apache configuration directory.

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

And include it add 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

Edit mythweb.conf to point it to the directory where you'll be installing 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.

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.so

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 open the /etc/httpd/conf/extra/mythweb.conf file and uncomment the authentication section (near the beginning):

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 how we have MythWeb set up, change the AuthUserFile so it reads

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're 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're using the 192.168.1.0 255.255.255.0 subnet)

Your config 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. Now we'll 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:

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

NOTE: No -c after initial user, otherwise you will overwrite the current file.

Now all we need to do now is restart the apache server for the changes to take effect.

# systemctl restart httpd.service

Troubleshooting

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

If you can't start the httpd service, and you get and error like this: journalctl -u httpd -xn ... AH00013: Pre-configuration failed ... Comment the line in httpd.conf: LoadModule mpm_event_module modules/mod_mpm_event.so

and use prefork module instead:

LoadModule mpm_prefork_module modules/mod_mpm_prefork.so
