So easy to fix but hard to find the solution. Hope this helps all you who are stuck with this. If your Apache server doesn’t start and you get an error message like this:
Failed to start apache : * Starting web server apache2 Syntax error on line 63 of /etc/apache2/sites-enabled/mythweb.conf: Invalid command 'SetEnv', perhaps misspelled or defined by a module not included in the server configuration Action 'start' failed. The Apache error log may have more information. ...fail!
It means you need to enable Apache module mod_env.
A simple check for the module with sudo a2enmod at the command line might show the following available modules:
actions alias asis auth_basic auth_digest auth_kerb authn_alias authn_anon authn_dbd authn_dbm authn_default authn_file authnz_ldap authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache cern_meta cgi cgid charset_lite dav dav_fs dav_lock dbd deflate dir disk_cache dump_io env expires ext_filter fcgid file_cache filter headers ident imagemap include info ldap log_forensic mem_cache mime mime_magic mod-security negotiation php5 proxy proxy_ajp proxy_balancer proxy_connect proxy_ftp proxy_http proxy_scgi reqtimeout rewrite setenvif speling ssl status substitute suexec unique_id userdir usertrack vhost_alias
Tell me if you can spot mod_env. I couldn’t and a 30 minute journey through Google couldn’t show me how to install mod_env.so. I eventually found a German forum where someone used ‘a2enmod env’. Guess what? ‘env’ is the name of the module needed.
When you need to enable mod_env, do it like this:
sudo a2enmod env
Then restart Apache with:
sudo service apache2 restart
My problem started after installing MythTV. Yours might start with Zend or something similar. Hope you found this page in your first search attempt. Please share and link back to JournalXtra to help others find this page quickly.
