http://www.vbseo.com/blogs/danny-bembibre/daemon-scripts-memcached-44/ <– memcached startup script for use with the chkconfig command. chkconfig is the "correct" way to manage services and what run levels they start and stop on. However, I've been known to also hack something into /etc/rc.d/rc.local when in a hurry. Best to use chkconfig unless you really know what you are doing.

Can’t compile memcached 1.4.5 on RHEL 5.5
./configure –with-libevent=/usr/lib64/
still results in error that libevent needs to be installed.
Installed libevent is libevent-1.4.13-1
linking /usr/lib64/libevent-1.4.so.2 to /lib64 or /usr/lib doesn’t help.
Has anyone been able to compile memcache on RHEL 5.5?

I got it working. The problem was that port 11211 was not open on the server.
In case somebody else run into this issue, here is a good article on how to open ports in linux:

my mistake, when I try doing the telnet command like this
$ telnet 192.168.1.102 11211
I get
Trying 192.168.1.102…
telnet: connect to address 192.168.1.102: Connection refused
telnet: Unable to connect to remote host

Sunny,

in the CentOS server, I ran this command to find out it’s IP address
# ifconfig
now I know the machine is running with this address: 192.168.1.102

then I ran this
# memcached -l 192.168.1.102 -p 11211 -d -u nobody

after that I ran this command to see if memcached is up and running:
# netstat -ant | grep LIST
at the top, I see this
tcp 0 0 192.168.1.102:11211 0.0.0.0:* LISTEN

I assume that means memcached is running on that ip address and port

now from another machine (MacOS), I open a terminal window and type the following:
$ telnet 192.168.1.102:11211
then I get this:
192.168.1.102:11211: nodename nor servername provided, or not known

does that mean the port is blocked or not opened in the CentOS server?

thanks for your help

Raul,

You can telnet to the instance. For example if you were running memcached on server with ip of 10.0.0.5 on port 11211, on windows you would goto command prompt and type: telnet 10.0.0.5 11211

if that doesn’t work and you know memcache is running and listening on that port, you may have firewall turned on. You can either allow that port or turn off the firewall to temporarily test. I suggest you figure out how to allow the port instead of turn off firewall completely.

This is a great tutorial; thanks for sharing it.

I have a CentOS server and followed your instructions to install MemCached on it.

My question is: how can I change the settings on CentOS to make MemCached accesible to other machines on my network?

I’m running a windows console application that uses Enyim.Caching and it seems that it can’t get to the Memcached instance.

How can I tell from a Windows machine if Memcached is up and running?

Thanks in advance.

Shannon, just for everybody’s knowledge here, are you using 32bit CentOS?

You can do following to check:
# uname -p

Update to my last comment:

–with-libeven should have been –with-libevent

Also, I did remember to run make install after I ran configure.

I Just finished installing on CentOS 5.1. Downloaded and built both libevent and memcached as instructed.

However memcached could not load the shared library libevent-1.3e.so.1.

Next I tried a “make clean” followed by
“./configure –with-libeven=/usr/local/lib” however I received the same error as before.

I was able to solve the problem by creating a symlink between /usr/local/lib/libevent-1.3e.so.1 and /usr/lib “ln -s /usr/local/lib/libevent-1.3e.so.1 /usr/lib”

Hopefully this will help someone else.

On CentOs 5.1 libevent may be installed like:

yum install libevent

but ‘yum install memcached’ still cant.

After this, you can download last version memcached

http://www.danga.com/memcached/dist/memcached-1.2.5.tar.gz

and go on as described abow, in some cases may apper this error

checking build system type… Invalid configuration `x86_64-unknown-linux-’: machine `x86_64-unknown-linux’ not recognized
configure: error: /bin/sh ./config.sub x86_64-unknown-linux- failed

for now, I duno how to deal against it, but will dig

Got the error: ./memcached: error while loading shared libraries: libevent-1.3e.so.1: cannot open shared object file: No such file or directory

The solution for me: libevent files where installed at /usr/local/lib, I had to move them to /usr/lib and check if symbolic links were correct.

Of course, you have to run the latest distro version to get the latest packages
memcached 1.2.4 is in Fedora 8.

Most of the times, using package managers to install won’t get you the latest version. With yum, it tried to download/install 1.2.3-7 on my fedora install. Thanks for the tip though. I am sure for people who don’t care, it would work out just fine.

On Fedora, a simple yum install memcached works better.
For Redhat 4 and 5, the same packages are available in the EPEL repositories:

i hate centos because of the package management. dag usually has a lot of extra packages: http://dag.wieers.com/rpm/packages/memcached/

looks like the latest there might be 1.2.2 though.
