Our deployment automation pulls Ignite from http://www.us.apache.org/dist/ignite/2.7.0/apache-ignite-2.7.0-bin.zip which is now an empty folder. Does it have a permanent home?
I think this is because 2.7.5 is now released. I guess this location only contains the last version. You can still download it from https://archive.apache.org/dist/ignite/2.7.0/apache-ignite-2.7.0-bin.zip

We are running a large amount of old EC2 instances which are based on Amazon Linux AMI 2014.09, a pretty old version.
We have recently built mod_jk on one of them that so that we can front Tomcat with Apache Web server 2.4.
We are in the process of identifying the dependencies of this mod_jk module. Can we re-use the mod_jk.so library that we just built with newer versions of the OS? We are running a large number of instances, so we would like to cut out the whole "building binaries from sources" step, so our ideal setup would be to take the current mod_jk.so binary and deploy it in all other EC2 instances.
The question is: can we safely do it? If not, when do we need to rebuild it? For example:
Do we need to rebuild it if we decide to launch EC2 instances with the latest Amazon Linux AMI, which is 3 years newer?
Do we need to rebuild it if the Apache's version is different?
Thank you in advance,
Meletis
I have a couple of precompiled mod_jk's in order to avoid just this cases. As per my own experience, I must recompile it in this scenarios:
Different Apache version (2.2/2.4)
Apache 32/64bits
As I stated before, according to this, you should have no more than 4 built mod_jk binaries to choose the right one from.
I could not tell you wether this is a best practice (probably not), but I have use this already built mod_jk in different Linux distributions and versions of Fedora, CentOS, Red Hat and Debian.
A penetration test has recently identified that one of our RHEL(6.7) servers running Apache 2.2.15 is vulnerable on a number of points and needs to be updated to the latest version 2.4. I have run yum update and it says that there are no packages marked for update. I understand that I will need to download the updates manually. There are a few questions I have around the requirement to upgrade Apache.
I am up to date on the 2.2 version tree. Does this mean that any security patches made to version 2.4 will be back patched to version 2.2.X as well?
I am running PHP (version 5.3.3) and MySQL (version 5.1.73) - will these be affected by upgrading the Apache version (Google tells me that there is no problem on both fronts - but I thought I'd ask before I started down this route).
If you experts tell me that I have no other choice but to upgrade, then I'm planning on using the instruction set here: https://unix.stackexchange.com/questions/138899/centos-install-using-yum-apache-2-4
Thank you in advance for your advice.
You could download the 2.4 source code from the Apache site and compile it. There's a setting which will configure for RedHat:
--enable-layout=RedHat
This setting will configure the paths for executables, configuration files, libraries etc in one go.
The following should be a reasonable starting point for a configuration line:
sh ./configure --enable-layout=RedHat --enable-mods-shared=all
then perform a make and make install
Do the same with a newer version of PHP (5.3.29 is available in the "old downloads" section, but try a newer version. Check the changes first though) and your problems should be lessened. Finally, MySQL or MariaDB is available for download and compilation too
Obviously, try all of this on a test machine first and back everything up. Your test machine should be as close as possible to your production machine. If you use something like VirtualBox to try it, you can take a snapshot at each point of the process and rollback if something goes wrong
I am currently using hadoop 1.0.3 version. I recently installed Apache Hive to run with it. I was running the select * query which gave me an NoSuchMethodError: org.apache.hadoop.mapred.JobConf.unset
I further found out its a compatibility issue with my current version of hadoop and requires me to upgrade to 1.2 or later.
I am fairly new to hadoop and would like to upgrade my current version to 1.2 or later. How do I go about doing the same.
I could not find any resources online to do so.
Thanks.
Just download hadoop 1.2.x from here and do necessary configuration changes in your new hadoop. Change HADOOP_HOME to point to your new hadoop folder.
NOTE: Change all the environmental variables (including .bashrc) to point to your new hadoop.
I have just upgraded our webserver from PHP 5.3.6 to 5.3.10, and I now want to upgrade Apache as well from 2.2.17 to 2.2.22 (on a Windows Server). How do I go about this in a good way (on a live webserver)? A little downtime is alright, but not too much.
Apache is installed via an MSI installer and I'm not sure how to upgrade safely with the least downtime.
Do I just download the latest installer and install that? And what about my config files? I don't think it's possible to have both instances installed 'next to each other'? Or is it?
For anyone else who searches for this, I found that uninstalling the old Apache (in my case, 2.2.22) from Add/Remove Programs and installing the new version (in my case, 2.2.24) kept all the previous settings.
We had locked down the httpd.conf file and had an application that modified/added files in the "htdocs" directory.
Upon uninstalling and re-installing, all of these files were left unchanged and the new version of Apache Server is reflected.
Download a latest version of apache installer.
Make the necessary config changes.
Run it on a different port, other than your live server.
If things work well, correct the port number, and replace.
It will really take a little down-time.
I did it today on windows server 2012R2, apache was installed from "source" (installer was not used-updated to 2.4.55):
1.Stop apache service
2.Rename apache directory (from C:\Apache24 to C:\Apache24-old)
3.Extract Apache24 folder from zip archive downloaded from apache web site to original location (C:\)
4.Copy conf folder from previous installation to the extracted folder (Copy C:\Apache24-old\conf to C:\Apache24\conf-overwrite)
5.(Optional), if you have any certs copy it from C:\Apache24-old\ to C:\Apache24
6.Start apache service,no issues faced
Good Day!
We have problem with issue AMQ-2736(https://issues.apache.org/jira/browse/AMQ-2736) on remote sites and wants to upgrade to 5.5.0 version, wich resolved this problem. But network connection with remote sites not stable and we will have non-empty KahaDB at some of them. Does 5.5.0 vesrion works with database created by 5.4.2 version and we can simply upgrade software or we must empty all queues before upgrade?
I do not know this from first hand experience, but a colleague has successfully used ActiveMQ 5.5 against a KahaDB created from a previous version. If you really want to try it out, just take a file system copy of the entire dataDirectory from version 5.4.2, and point your 5.5 installation to that copy within your activemq.xml configuration.
I tried latest Fuse Message Broker maintenance release for ActiveMQ 5.4.2 - apache-activemq-5.4.2-fuse-02-00 - and it works good - all "trash" files are removed and we have not detected any message lost or corruption
