Trouble with Empresa 5.26 installation on CentOS 7.3 64 bit

[tmallardi]

Hello,

I'm encountering an Internal Server Error when attempting to run a compiled Miva script.

The following message is in /var/log/messages:
Jan 2 20:59:18 server kernel: mivavm[13171]: segfault at 8 ip 00007f8f761c63b8 sp 00007ffd8e4950c0 error 4 in ld-2.17.so[7f8f761bb000+20000]


The following message is in /usr/local/apache/logs

[Mon Jan 02 20:59:18.762334 2017] [cgi:error] [pid 12945] [client (my IP address):4586] End of script output before headers: mivavm



I am attempting to install Empresa 5.26 in the following environment:

CENTOS 7.3 x86_64 on a cPanel virtual server with the latest WHM v60

I've decided to use the 3.x Standard Mode installation so the Miva VM will be available to only one virtual domain.

I followed these docs:
http://docs.mivamerchant.com/en-US/m...vm_on_unix.htm

I downloaded the Linux 64bit tar file. (not glib or fastCGI)


Given that I didn't miss any steps, what would be the best approach to troubleshooting this problem?

I did remember to install the .htaccess file.


One part that I'm not familiar with on my new server environment is "suexec" and what role that plays with the Standard Mode installation.



Any guidance would greatly be appreciated.

Thanks,
Tim

If you downloaded the tar to your local machine - re-upload the mivavm using binary mode (set in your ftp client).
That has always been the case when I have seen this. But I have almost zero experience with cPanel.

It's important to use suexec in a standard mode install; it ensures that the Empresa binary is running as the user associated with the website in question. This means the data directory, and any files it needs to update, need only be owned by the site user and no group or world writable perms. For the data directory, it should be inaccessible to group/other. Suexec will also refuse to run an executable if it's owned by anyone other than the user configured for the site, if the parent directory is group or other writable, and a few other checks.

In any case, I wouldn't think it's an suexec issue or you wouldn't be logging a segfault since it would never make it to the point of trying to execute the binary.

I'd do three things:

1. What Bill suggested is good; if you did download and extract on a local system, perhaps the file didn't make it to the server correctly.
2. A way to avoid the above is to just download and extract on the server; you'd do this:
   1. wget http://www.miva.com/miva-software/em...nux_x64.tar.gz
   2. tar zxvf mivavm-v5.26-linux_x64.tar.gz
   3. The binary will be at mivavm-v5.26/cgi-bin/mivavm-v5.26 for you to move to wherever it's needed
3. Run an md5sum against the binary. The non-glibc23 and non-fastcgi 64-bit version of empresa should produce the following signature:

# md5sum mivavm-v5.26/cgi-bin/mivavm-v5.26
abacf53eba9745656cb7519b61ddadcd mivavm-v5.26/cgi-bin/mivavm-v5.26

If you see a string different than the above, then it sounds like the file is not correct. You can also test with the file command and/or ident commands to see if they produce any errors:

# ident mivavm-v5.26/cgi-bin/mivavm-v5.26

RESOLVED

Bill & David,

I really appreciate your quick replies!

Apparently it was a problem with the upload using my FTP client.
When I used David's wget steps, it worked like a charm.

This community has always been such a great & supportive user base.

Thanks,
Tim Mallardi
