I can start apache with same configuration in a test box where I have installed Apache + SVN without any issue.

But copying all necessary binary files to a Production box and starting apache over there creating the above mentioned error.

I have verified that there is no issue with LD_LIBRARY_PATH and all the contents of Test box is copied to production box by creating tar file and doing sftp.

Even though I deleted all Apache + SVN reference from production box and installed Apache + SVN modules afresh in Test box and copied the binaries once again from Test box to production box, same error is occurring.

But I can start apache module only without SVN modules (i.e by removing mod_dav_svn.so and mod_authz_svn.so from httpd.conf)

Below is the way I have installed SVN in Test box.

tar jxf subversion-1.8.11.tar.bz2
cd subversion-1.8.11           

./configure --prefix=/ngs/app/apstoold/ApacheAndSVN/subversion --disable-static --with-expat=/ngs/app/apstoold/ApacheAndSVN/Libexpat/include:/ngs/app/apstoold/ApacheAndSVN/Libexpat:lib --with-apxs=/ngs/app/apstoold/ApacheAndSVN/httpd/bin/apxs --with-apr=/ngs/app/apstoold/ApacheAndSVN/library/bin/apr-1-config --with-apr-util=/ngs/app/apstoold/ApacheAndSVN/library/bin/apu-1-config

make
make install

I have the following versions installed.

Server: Apache/2.4.12 (Unix) OpenSSL/1.0.2 SVN/1.8.11 PHP/5.5.21

Can someone please help me out.

Thanks

You have obviously a dependency problem. I do not know which distribution you are using but I guess(!) you have manually updated SVN to 1.8.x and have run into these problems. There are multiple problems possible:

  1. you have a problem with libapache2-svn 2.2 vs. 2.4
  2. you have a problem with libsvn1 1.6.x/1.7.x vs 1.8.x
  3. you may have an loadmodule dependency problem see here: https://serverfault.com/questions/540873/problems-after-updating-svn-to-1-8-3-on-ubuntu-12-10-using-wandisco-package

  • Hi Peter, Thanks for the update. But I am clueless over here. In both source and destination (Test box as well as Production box) I am using Linux system (Linux 2.6.39-400.214.4.el6uek.x86_64 x86_64) and I have not updated SVN to 1.8 manually. I have installed following modules (openssl-1.0.2, httpd-2.4.12, pcre-8.36, apr-1.5.1, apr-util-1.5.4, expat-2.1.0, subversion-1.8.11, php-5.5.21) and have set LD_LIBRARY_PATH properly. Any help is greatly appreciated. – user3583381 Mar 28 '15 at 20:41
  • I think you compiled the SVN with apache 2.2 support. check for a parameter there. – Peter Parker Mar 30 '15 at 16:46
