    Default Apache2 start problems

    Hallo
    Yesterday I installed LAMP on my computer (opensuse13.1 /64bit / KDE) using the comand:
    Su
    yast2 --install patterns-openSUSE-lamp_server

    It seemed to function and the index.html test site was shown properly in the browser/localhost. Then I had problems bringing the php to work, I don´t remember what exactly I´v done/experimented...anyway, apache2 don´t start anymore:
    Code:
       
    
    systemctl start apache2.service
     Job for apache2.service failed. See 'systemctl status apache2.service' and 'journalctl -xn' for details.
    and:
    Code:
       
    systemctl status apache2.service
     apache2.service - The Apache Webserver
        Loaded: loaded (/usr/lib/systemd/system/apache2.service; enabled)

    Please post /etc/sysconfig/apache2.
    Your error messages indicate that you enabled SSL, but just doing that without other necessary steps won't work.
    So disable it again (variable "APACHE_SERVER_FLAGS" in that file, or run "sudo a2enflag -d SSL").

    For enabling PHP5 support you have to add "php5" to the variable "APACHE_MODULES" or run:
    Code:
    sudo a2enmod php5

    Thanks for the fast answer.
    here the results:
    Code:
    /etc/sysconfig/apache2
    bash: /etc/sysconfig/apache2: Datei oder Verzeichnis nicht gefunden (file or folder not found)
    I hope I didn´t make to much mess here with my experiments.
    Another detail: the problem started after the first computer reboot: apache2 started but I had no internet connection (no browser/thundurbird/ftp connections) so I changed in the network settings(Yast2) from "user controlled with NetworkManager" to "Traditional Method with ifup". I addmit that I don´t really understand it but it worked, so have back internet connection but no apache2 anymore, even if I change it back to "user controlled with Networkmanager".

    First, you tried to execute the file. I asked for the _content_.
    Second, it appears you don't have that file at all.

    I hope I didn´t make to much mess here with my experiments.
    What experiments?
    Apparently you deleted /etc/sysconfig/apache2, which is bad enough.
    Did you also randomly change config files in /etc/apache2/? I hope not.

    The easiest way to get back /etc/sysconfig/apache2 is to reinstall the apache2 package:
    Code:
    sudo zypper in -f apache2
    If you did change the configuration files it's probably better to just delete the whole directory /etc/apache2 before you re-install apache2. A default configuration will then be created from scratch. But in this case you should also re-install apache2-mod_php5, apache2-mod_perl, and aopache2-doc to regenerate their config as well.

    Another detail: the problem started after the first computer reboot: apache2 started but I had no internet connection (no browser/thundurbird/ftp connections) so I changed in the network settings(Yast2) from "user controlled with NetworkManager" to "Traditional Method with ifup". I addmit that I don´t really understand it but it worked, so have back internet connection but no apache2 anymore, even if I change it back to "user controlled with Networkmanager".
    Of course not.
    You broke your Apache, that's unrelated to the way you connect to the internet.
    Btw, a user connection with Network Manager only gets established when the user logs in, that's far too late for Apache obviously, which is normally started during boot already.
    If you want to run a web server, you should use ifup, or setup a system connection in NetworkManager.

    If you switch to ifup, you have to setup your network connection in YaST as well. You probably didn't, that's why you had no connection afterwards. This is especially true for a wireless connection, a wired one should actually work without configuring anything most of the time.

    After reinstalling apache2 here the /etc/sysconfig/apache2:

    Code:
    ## Path:    Network/WWW/Apache2
    ## Description:    Configuration for Apache 2
    
    ## Type:    string
    ## Default:    ""
    ## ServiceRestart: apache2
    #
    # Here you can name files, separated by spaces, that should be Include'd from 
    # httpd.conf. 
    #
    # This allows you to add e.g. VirtualHost statements without touching 
    # /etc/apache2/httpd.conf itself, which makes upgrading easier. 
    #
    APACHE_CONF_INCLUDE_FILES=""
    
    ## Type:    string

    #
    # Here you can name directories, separated by spaces, that should be Include'd 
    # from httpd.conf. 
    #
    # All files contained in these directories will be recursively included by apache.
    # If a pattern like *.conf is appended, apache will use it.
    #
    # Examples: "/etc/apache2/my_conf/"
    #           "/etc/apache2/virtual_hosts/*.conf"
    #           "local/*.conf /srv/www/virtual/"

    ## ServiceRestart: apache2
    #
    # [It might look silly to not simply edit httpd.conf for the LoadModule statements.
    # However, since the LoadModule statements might need an absolute path to the modules,
    # switching between MPMs can be quite a hassle. It's easier to just give the names here.]

    # * It pays to use IfDefine statements... like
    #    <IfModule mod_xyz.c>
    #        ....
    #    </IfModule>
    #
    # * In the APACHE_MODULES variable, you can use mod_xyz or just xyz syntax.
    #   You may also name an absolute path if you like.
    #
    # * NOTE ON SSL: before you can use mod_ssl, you need a server certificate. 
    #   A test certificate can be created by entering 
    #   'cd /usr/share/doc/packages/apache2; ./certificate.sh' as root.
    #   Also, you need to set the ServerName inside the <VirtualHost _default_:443> 
    #   block to the fully qualified domain name (see /etc/HOSTNAME).
    # * if your server certificate is protected by a passphrase you should increase the
    #   APACHE_START_TIMEOUT (see above)
    # * to finally enable ssl support, you need to add 'SSL' to APACHE_SERVER_FLAGS 
    #   below.
    #
    # * modules listed here will be ignored if they are not installed
    #
    #

    #             something temporarily.

    Good.
    Btw, you can use YaST->Security and Users->Firewall as well to change the firewall configuration.
