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:

• Centmin Mod 1.2.3-eva2000.08 stable install & update thread
• Centmin Mod 123.09beta thread
• Example of centmin.sh menu option 23 git updating code.

doh fixed a typo just committed

 

ran into bug on fresh 123.09beta01 install

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

 

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

 

pretty close !

 

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



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

 

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

 

yup as you found out

 

in theory any variable in centmin.sh above line 789 source include line can be overridden in custom_config.inc but example is included in 123.09beta01 at example/custom_config.inc at centminmod/custom_config.inc at 123.09beta01 · centminmod/centminmod · GitHub
