Vanilla install failing

  • I’m attempting to do a vanilla wordpress install on an AWS micro instance. I start by running the following commands on Ubuntu 14.04 on a new VDI:

    sudo apt-get update
    sudo apt-get dist-upgrade
    sudo apt-get autoremove
    sudo apt-get install apache2 php5 mysql-server mysql-client

    Then I move the latest install of wordpress over and unzip and copy it over to the root and set the permissions:

    unzip wordpress-4.6.1.zip
    sudo cp -r /home/ubuntu/wordpress/* /var/www/html/
    sudo chown -R www-data *
    sudo chmod -R 744 *

    Then when I navigate to the home directory, I get a “ERR_EMPTY_RESPOSNSE” in chrome. Looking at the logs, I have the following errors:

    [Fri Sep 23 07:41:11.927161 2016] [core:notice] [pid 26789] AH00051: child pid 26795 exit signal Segmentation fault (11), possible coredump in /etc/apache2
    [Fri Sep 23 07:42:58.046432 2016] [core:notice] [pid 26789] AH00051: child pid 26794 exit signal Segmentation fault (11), possible coredump in /etc/apache2
    [Fri Sep 23 07:46:29.232901 2016] [core:notice] [pid 26789] AH00051: child pid 26793 exit signal Segmentation fault (11), possible coredump in /etc/apache2

    I checked /etc/apache2 and there is nothing.

    Since it’s a vanilla install, I’m perplexed. I’ve done this same install procedure ~10 times and it always works out of the box. This should work unless I’m missing a package. I also tried the package managed version of wordpress on 16.04 and tried (almost) the same install process on 16.04 to get the same result. Is there a bug that has been introduced with the latest version?

  • I think something has gone wrong somewhere. All my sites have updated to the latest version, whenever I login to the /wp-admin section the “WordPress News” which normally gets populated is sitting there blank.

    I tried to run updates, changes themes and even do plugins and it all comes back with errors, looked at the apache log and all I’m getting is seg faults.

    So I did a bit of further troubleshooting and packet sniffing…

    It looks like there is an issue with api.www.ads-software.com (WordPress API System).

    This is causing the segfaults.

    I have the same problem.

    I think it has something to do with network connections and certificate verification.

    Following is a strace output, showing that it segfaults after processing the ca-bundle.crt file:

    If you rename the file (/wp-includes/certificates/ca-bundle.crt), you can use at least use some of the function of wordpress. Of course everything that connects to api.www.ads-software.com does not work that way.

    I also have a freshly installed wordpress 4.6.1 downloaded today and a Ubuntu 16.04 installed and updated today.
