Solr fails to start with log file not found error
I get this error when starting Solr using the script in bin/solr
tail cannot open `[path]/logs/solr.log’ for reading: No such file or directory
It does not happen every time, but it does happen a lot. It sometimes clears up after a while.
I have tried creating an empty file, but solr then just says:
Backing up [path]/logs/solr.log
And repeats the same error.
I am guessing the problem is that it cannot get the error from the log file because the log file has not been created yet, but then how do I debug this?
Running Solr 4.10.2 on Debian 7 using Jetty with the default IcedTea 2.5.3 java version 1.7.0_65
Thanks for any help or pointers.

Thanks for the reply, Shawn.
But it seems to give me only 1.7.
#sudo rpm -qa | egrep "(java|jdk)"
java-1_7_0-openjdk-1.7.0.85-18.2.x86_64
libjavascriptcoregtk-3_0-0-2.4.8-16.2.x86_64
java-1_7_0-openjdk-headless-1.7.0.85-18.2.x86_64
timezone-java-2015g-0.26.1.noarch
# update-alternatives --config java
There is only one alternative in link group java (providing /usr/bin/java):
/usr/lib64/jvm/jre-1.7.0-openjdk/bin/java
Nothing to configure.
#update-alternatives --config javac
update-alternatives: error: no alternatives for javac

This error message means you're trying to start Solr with Java 6, not
Java 7. You might have OpenJDK 7 on your computer, but you also have an
older version, and the older version is the one that is being used.
I understand that suse uses RPM, so run this command to see if Java 6 is
installed with a package:
rpm -qa | egrep "(java|jdk)"
If it is, then you should be able to uninstall it and let version 7 have
center stage.
On a CentOS 6 system, I get this output by running that command. I've
got Java 8 installed on this system:
[root@mcp ~]# rpm -qa | egrep "(java|jdk)"
java-1.8.0-openjdk-1.8.0.51-3.b16.el6_7.x86_64

Hi, I'm newbie on solr, but have same issue.
More precisely, only one machine can't start solr with the message, "cannot
open {solr.log} file for reading: No such file or directory." Obviously
there is no file and even I created empty one, it doesn't help.
I've tried also - moving around the directory here and there, changing
owner/group like root/myself/solr:solr, use install_solr_service.sh or just
unzip, etc, but this machine doesn't allow to start.
Not working one is solr 5.2.1/SLES 12.
But I have working one with solr 5.2.1/SLES 11 and solr 5.2.1/Ubuntu 14.
>From the log left in sol-8983-console.log is as follow.
I'm using OpenJDK 1.7 as follow.

Re: Solr fails to start with log file not found error

I use the same user every time and the /logs directory and everything in it is owned by that user. I get the same problem occasionally developing on my Ubuntu 14.10 laptop as well, and all the files in the solr directory are owned by me on that machine (and I run Solr as me there as well).
Config issue? Is there anything that could cause this?

By any chance are you trying to start Solr as a different user when
this happens? I'm
wondering if there's a permissions issue here....
Wild guess.
