    Memcached Server 1.4.26 Updated



    Updated both Centmin Mod 123.08stable and 123.09beta01 builds to default to Memcached server 1.4.26 release. Once you update your local server Centmin Mod branch code via centmin.sh menu option 23 outlined below. You will need to exit centmin.sh and re-run centmin.sh again and run centmin.sh menu option 10 to update Memcached server to 1.4.26.

    Centmin Mod script will also auto update your memcached /etc/init.d/memcached file with new Memcached 1.4.26 -o modern option if it detects Memcached 1.4.26 version running. As such you will need to exit centmin.sh after menu option 10 run and re-run centmin.sh one more time to get centmin.sh to auto update /etc/init.d/memcached.

    The centmin.sh will auto patch /etc/init.d/memcached even if you do this last step later or skip it whenever the next time you run centmin.sh and it detects Memcached 1.4.26 running and the new option is not in place.

    To update your Centmin Mod builds follow instructions at centminmod.com/upgrade.html and respective version threads below:

    make: *** No targets specified and no makefile found.  Stop.
    make: *** No rule to make target `install'.  Stop.


    seems memcached-1.4.26.tar.gz was never extracted after download due to bundling with downloads/svr-setup.zip skipping the routine to download and extract
    Code (Text):
    ls -lahrt /svr-setup/ | grep memcached
    -rw-r--r--   1 root  root    69K May 31  2015 memcached-2.2.0.tgz
    -rw-r--r--   1 root  root  1016K Jun 20  2015 libmemcached-1.0.18.tar.gz
    -rw-r--r--   1 root  root   352K Nov 23  2015 memcached-1.4.25.tar.gz
    -rw-r--r--   1 root  root    13K May 19 03:48 lua-resty-memcached_v0.14.tar.gz
    -rw-r--r--   1 root  root   1.6M Jun 21 14:59 memcached-1.4.26.tar.gz


    edit: looks like bundled memcached is corrupted
    Code (Text):
    tar xvzf memcached-1.4.26.tar.gz
    
    gzip: stdin: not in gzip format
    tar: Child returned status 1
    tar: Error is not recoverable: exiting no


    redownloaded the memcached-1.4.26.tar.gz for inclusion in downloads/svr-setup.zip to fix it for new initial 123.09beta01 installs only. No problems with 123.08stable as i have yet to update downloads/svr-setup.zip with 1.4.26 tarball so centmin.sh just downloads it fresh from memcached.org official site anyway

    edit: updated 123.09beta01 with additional fallback checks to see if memcached related routine in centmin.sh menu option 10 and initial install properly extracted the relevant tarballs. If not, automatically delete the existing tarball from /svr-setup and redownload it and extract it again :)

    No update to the php module correct, just the server binary?

    yup.. though centmin.sh menu option 10 does update memcached sever and recompile memcache/memcached existing versions all at once to make sure everything is on same page

    found the culprit

    ah problem is official site memcached.org version of download is not 100% valid see below screenshot the one at 1600KB is memcached.org downloaded one and below is one i redid a tar + gzip on

    upload_2016-6-22_10-1-7.png

    IIRC, this is not the first time memcached.org has served up invalid tarball

    latest 123.09beta01 has added detection for such and redownloads from local centminmod.com mirror if detected as invalid Beta Branch - fallback checks if memcached routine tarballs extracted properly in 123.09beta01 | Centmin Mod Community

    So I have memcached 1.4.26 running, but are these the latest?

    Code (Text):
    memcached support => enabled
    Version => 3.0.0b1
    libmemcached version => 1.0.16
    

    You have 1.0.18 in your srv-setup, but are compiling against 1.0.16, or am I missing a config option somewhere?

    Centmin Mod switched to remi yum rrpo 1.0.16 just to speed up install times was hoping remi version would get updated eventually

    FYI, centmin.sh has a variable to control this as well
    Code (Text):
    LIBMEMCACHED_YUM='y'        # switch to YUM install instead of source compile

    set in persistent config /etc/centminmod/custom_config.inc can override the default ='y' enabled value as
    Code (Text):
    LIBMEMCACHED_YUM='n'        # switch to YUM install instead of source compile

    So put this in /etc/centminmod/custom_config.inc and option 10 to recompile memcached, is that all that is required?

    Thanks @eva2000, is there documentation of the variables in centmin.sh that we can override in custom_config.inc?

    Or are all the variables you define in centmin.sh changeable in custom_config.inc?
