Error /var/lock/zm & /tmp/zm

[skydiver]

I am upgrading what was an existing 1.28 ZM running on Ubuntu server 14.04 LTS. While performing the upgrade, my configuration and database disappeared so I am treating this like a fresh install.The system is currently running but I cannot stream.

Following the install wiki for Ubuntu, I get to the init.d restart ad I am getting the following errors when starting the service:

Code: Select all

Stopping ZoneMinder: 
success
rm: cannot remove /var/lock/zm: Operation not permitted
Starting ZoneMinder: chown: changing ownership of /var/run/zm: Operation not permitted
chown: changing ownership of /tmp/zm: Operation not permitted
success

I have confirmed that the directories and files re chown'ed www-data:www-data

Additionally I have the following errors in teh zonemnder logs:

Code: Select all

2016-03-20 15:10:25.830110	zmdc		20767	ERR	'zma -m 1' exited abnormally, exit status 255	zmdc.pl	
2016-03-20 15:10:25.693152	zma_m1		20797	ERR	Shared data not initialised by capture daemon for monitor Backyard	zm_monitor.cpp	442

I have a feeling that my configuration may be off due to the prior now disappeared installation. Where do I fix the run and lock errors? I am sure this will lead to new problems.

See the upgrade instructions:

https://wiki.zoneminder.com/Common_Issu ... PA_version

I had already followed the
Ubuntu 14.04 - ZM 1.26.5 or later to 1.29.0 or the latest PPA version

instructions and that is how my old 1.28 setup along with 4 years of events got reset (my own fault for not having a backup)

I just went through again and still the same result. Can you provide some direction as to what setting needs to be looked at for these two process files?

[skydiver]

OK did it a third time this time as sudo su instead od sudo each comnad and that seemed to fix the tmp/lock issues.

Now I still cannot stream. This is the error in the ZM logs:

2016-03-20 20:51:13.941936 web_js 28352 ERR getStreamCmdResponse stream error: socket_sendto( /var/run/zm/zms-661580s.sock ) failed: No such file or directory - checkStreamForErrors() ?view=watch
2016-03-20 20:51:13.707367 web_php 28352 ERR socket_sendto( /var/run/zm/zms-661580s.sock ) failed: No such file or directory /usr/share/zoneminder/www/includes/functions.php 2371

[skydiver]

Any help here? I have RTFM'd both the upgrade and fresh install with no luck.

[bbunge]

Can't stream is usually the result of:

1. CGI not enabled (since you had 1.28 running this is not the case)

2 The final step in the upgrade process: Open Zoneminder. Click on Options - Paths, Change PATH_ZMS to /zm/cgi-bin/nph-zms

Oh, make sure these is no space at the end of: /zm/cgi-bin/nph-zms

[skydiver]

Still cannot stream. Have verified all the settings for both urgrading from 1.28 on Ubuntu Server LTS 14.04 and a new install.

Here are some settings from the systems:

Where else do I need to look to get streaming to work?

Your apache config file is from the previous version of ZoneMinder. You should be using the one the ships with the 1.29.0 package.

First, verify the new config file is located under /etc/apache2/conf-available/ and it looks like this:

Code: Select all

# Remember to enable cgi mod (i.e. "a2enmod cgi").
ScriptAlias /zm/cgi-bin "/usr/lib/zoneminder/cgi-bin"
<Directory "/usr/lib/zoneminder/cgi-bin">
    Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
    AllowOverride All
    Require all granted
</Directory>

Alias /zm /usr/share/zoneminder/www
<Directory /usr/share/zoneminder/www>
  php_flag register_globals off
  Options Indexes FollowSymLinks
  <IfModule mod_dir.c>
    DirectoryIndex index.php
  </IfModule>
</Directory>

<Directory /usr/share/zoneminder/www/api>
    AllowOverride All
</Directory>

Second, delete the old config file apache2.conf under /etc/zm/ and also delete the symlink that points to it under /etc/apache2/conf.d.

Now go to /etc/apache2/conf-enabled and create a symlink that points to zoneminder.conf in ../conf-available.
There is some Debian command which will do this for you, but I don't use Debian so maybe someone else can tell you what it is.

Restart apache and zoneminder, and you should be good to go, provided your PATH_ZMS under Options is correct.

This completely stupid way of configuring apache is one of the reasons I stick with redhat distros.

rm /etc/apache2/conf-enabled/zoneminder.conf

Neither of these suggestions worked. Still getting these errors when trying to stream.:

It is recording events and the stills are view-able, just no streaming.

[knight-of-ni]

That means you've still got an Apache configuration problem somewhere.

[bbunge]

Looks like your best bet is to start over with a fresh install of Ubuntu server.

I am running two other lightweigtht websrvers on this Apache server, so I really don't want to wipe this. Can someone please step through what is causing the error?

What processor & configs files are determining what launches where wand where the pid loock files are needing to be written to?

[skydiver]

So let me re-phrase my question:
When you are logged into the zm Apache page and then request a stream to view, Apache attempts to start streaming.
Where does in the Apache the configuration does Apache look to start the zm streaming process?
Where in the streaming process does the binary look to write files?
I am assuming that since the apache process is running as www-data that all other spawned processes are also running as www-data. What file ownership does the streaming process need to be able to work?

[skydiver]

What file ownership should the usr/lib/zoneminder folders have?
