How can i fix this problem ? Have a good day
As written in the error message, there seems to be no /var/log/apache2 directory or it is not writeable for the user running your apache daemon.

I have installed the solr service on a LINUX environment. Now trying to start the service using the below command
service solr start
After executing this command, am getting below error from the server
Waiting to see Solr listening on port 8080 [-] Still not seeing Solr listening on 8080 after 30 seconds!
tail: cannot open `/var/solr/logs/solr.log' for reading: No such file or directory
I created the solr.log file manually and placed it under the above mentioned path, But as soon, i issue the command "service solr start" . The solr.log file will be renamed and there won't be any new file created with the solr.log. hence the service fails to start. Could anyone let me know how to tackle this issue.
Thanks in advance.
I had a similar issue, and was able to find a hint in the /var/solr/logs/solr-8983-console.log
Originally I had been using Java 8, and Solr was working just fine for me.
When I switched to Java 11, Solr would have the issue you reported.
The log file contained the following:
Java HotSpot(TM) 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
Unrecognized VM option 'UseParNewGC'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
I switched back to Java 8 and Solr started just fine.
First, did you use the procedure provided to install the Solr service page 461
Second, did you set the proper overrides to the environment defaults in a solr.in.sh script (p. 462 of the ref manual). You also need to make sure that the LOG4J_PROPS in the solr.in.sh file points to your log4j.properties file. Also make sure that SOLR_LOGS_DIR is pointing to the correct place.
If all that is correct, then check that the values in your log4j.properties file are set correctly (p. 468 of the ref manual).
You can get the reference manual here: https://www.apache.org/dyn/closer.lua/lucene/solr/ref-guide/ if you don't have it already.
I had a tough time getting Solr to run as a service, but in the end I simply wasn't reading carefully enough.
I've installed Solr on my Ubuntu to this path
/opt/solr/solr-4.10.2
After installing I started Solr:
sudo bin/solr start from /opt/solr/solr-4.10.2 directory
As I can understand it started successfully
Waiting to see Solr listening on port 8983 [/]
Started Solr server on port 8983 (pid=8385). Happy searching!
But when I try to get to admin page
http://localhost:8983/solr
I got 404 error:
HTTP ERROR: 404

Do you have any suggestion what's going wrong and where to look in order to fix this problem?
Since this error can be caused by a lot of things, you need to access the log file and debug the execution.
First of all, open your Node log file, located in /opt/solr/solr-4.10.2/node1/log and look for something weird (Shift+F for Errors).
Generally, this error occurs when you have a mismatch between the Solr required Java JDK and your current Java JDK.
When I had this problem, I found in the log file the following error message java.lang.UnsupportedClassVersionError: org/apache/solr/servlet/SolrDispatchFilter : Unsupported major.minor version 51.0 and realized the problem was the java version.
To solve this, try to change the current JDK, using the command sudo update-alternatives --config javac.
If the error still occurs, try to uninstall all unused JDK's, because Solr is getting the wrong path.
The final solution to this issue is to open the file /opt/solr/solr-4.10.2/solar.in.sh and edit the SOLR_JAVA_HOME, writing the right JDK path (e.g /usr/lib/jvm/java-1.7.0)
Disclosure: the secret is look in the log file and figure out what is causing the issue.
Cheers.

I have a projects in cakephp which is a big size projects.. It is running perfectly in another computer or in the server. But when I copy the files and database to my local computer then it shows the following error.
Fatal error: Maximum function nesting level of '100' reached, aborting! in D:\wamp\www\faceadz\cake\libs\debugger.php on line 248
Project is running in wamp server.
Please help me...
thanks
there might be 2 solution will work for you in you local machine configuration
1. A simple solution solved to your problem. you can just commented the:
"zend_extension = "d:/wamp/bin/php/php5.3.8/zend_ext/php_xdebug-2.1.2-5.3-vc9.dll"
in your php.ini file. This extension was limiting the stack to 100 so I disabled it. The recursive function is now working as anticipated.
2. and
Assuming you're using xdebug, you can set your own limit with
ini_set('xdebug.max_nesting_level', $limit)
EDIT
Also it will help you
changes the file /etc/mysql/my.cnf parameter to something like that max_allowed_packet = 512M
Get sure you've got xdebug installed (use phpinfo()) and then change the file /etc/php5/fpm/php.ini adding or editing the line : xdebug.max_nesting_level=1000
Restart both services sudo service mysql restart sudo service php5-fpm restart
If it doesn't work you can still set those two parameters to false at /etc/php5/fpm/php.ini xdebug.remote_autostart=0 xdebug.remote_enable=0
hope it will help you,
I am getting this error on an existing server. No configuration change. Suddenly, it happened. The log shows nothing, except something similar to the following:
10.10.10.11 - - [28/Oct/2011:01:01:08 +0800] "POST /notexist HTTP/1.1" 500 50 "-" "PECL::HTTP/1.7.1 (PHP/5.3.8)"
Until now I figured out that it is occurring only while using HTTP POST, it does not seem to be related to any CGI or PHP script.
I've recompiled Apache but the problem still exists. I wrote a script to visit a none exist URI of the server by using GET and POST. While requesting a GET, apache response 404, but for a POST, its response is a 500 error immediately.
Can anyone let me know what can I do?
I am using FreeBSD and the Apache is compiled by using event MPM.
Thanks in advance for any help.
PS. I've found it is related to subversion 1.7.1, While I reinstalled subversion 1.6.17 port, Apache seems to be working again. I am sorry to post this question here, maybe I should report this problem to FreeBSD subversion port administrator. It's weird because it doesn't happen when I upgrade to subversion 1.7.1, and it happened when there is no configuration change.
See http://svn.haxx.se/users/archive-2011-10/0457.shtml. It is a confirmed bug in Subversion 1.7.0 and 1.7.1. It's fixed in Subversion trunk with r1187695 which is proposed to be included in a following 1.7.x-release (see http://svn.apache.org/repos/asf/subversion/branches/1.7.x/STATUS).
