I have been attempting to install ConcreteCMS 9.2.0.
Using a manual install to httpdocs folder as per concrete.com installation.
Host is Plesk PHP 8.1.16, MariaDB 10.6.
Part way through the web install I get the following installation fail:
SessionHandler::read(): open(/var/lib/php/session/sess_a83i2v9jgo19k1b15vsgqhke67, O_RDWR) failed: No such file or directory (2).
As a cross check I unzipped 9.2.0 in Windows 11.
Windows properties shows 143MB, 20845 files, 3528 folders.
I then proceded to upload the extracted folder and files to the Plesk file manager Home folder.
After a lengthy period the upload failed because of missing paths.
As @Johnthefish has said elsewhere it pays to wait for one or two revisions of a new CMS until the bugs are ironed out.
So, with that in mind I attempted to do a manual install of ConcreteCMS 9.1.3 on my Plesk host PHP 8.1.16 with MariaDB 10.6.
No luck with the install.
Part way throught the install I get the same error message as in 9.2.0:
SessionHandler::read(): open(/var/lib/php/session/sess_ta9lqjrta7c3ad1maagkf39vjk, O_RDWR) failed: No such file or directory (2).
I donāt want to start using Composer.
I am seriously considering moving to Hostdash or A2hosting which supports ConcreteCMS.
From your plesk file manager, see how much of that (No such file or directory) path exists.
Php (and hence Concrete) tracks data pertinent to each user in a temporary file called a āsessionā file. The message suggests that your host php setup is not configured to use a directory that your web account php has access to. It is usually a php ini file setting.
This problem will be common to all php applications that keep a session, not just Concrete CMS.
Your host support team should be able to advise you on whether the above suspicion is correct and on how to configure it in your plesk account.
While you have the support teamās attention, get them to also check through the other php ini settings. If they have missed configuring one setting for your account, there could be others (for example, memory allocation).
Are you trying to restore a compressed backup copy of your entire previous site folders and dB?
Iām not sure what the chances of that working would be, especially after decompressing in Windows and uploading. The original file and folder permissions and ownership settings may not survive that process.
If you use your server to compress and then decompress you may have better successā¦, if permissions and ownership were included in the original compression process.
If I recall correctly, I think one of your other post suggested you were going to install a new empty site and get a fresh start. If thatās an option, does that work? If not, whatās the difference between the host adminās test server environment and yours?
I have given up on playing about with Windows decompression versus Plesk decompression.
For my attempted installs I am using the Plesk decompression of ConcreteCMS 9.2.0 .zip.
The current investigation is why canāt I install a new empty site using ConcreteCMS 9.2.0.
My website host has successfully installed an empty site using 9.2.0 on a test server.
My attempt to install an empty site on my host server using 9.2.0 still fails.
I am waiting to hear from my host admin about the differences between their test server success and my failed install.
Just received an email from my host admin saying that my issue has been escalated to their engineering team
I will pass that on to my host admin the reboot options you suggest.
When attempting a new install of ConcreteCMS I have simply deleted all previous files and removed the DB.
Then uploaded a new zip to my host.
Decompressed the the zip and moved the required files to httpdocs.
Then created a new DB.
Then attempted to complete the install using my website URL.
I now have ConcreteCMS 9.2.0 up and running and I am rebuilding my website.
Plesk PHP 8.1.16 and MariaDB 10.6.
My host admin called on their engineers for help.
A new database was created leaving behind my old database.
Further tweaks by host admin a day later allowed me to successfully login and edit my website.
Happy again
Iām glad to hear that everything is running with current versions. Did the host admin give any further details on what they thought was wrong with the previous database(s)? If so, please post, it may help someone in a similar situation.
After asking my host admin for more details I received:
Iāve asked the Engineer who worked on your Concrete CMS installation and see his response below.
-Create a new database before the installation and delete the old database that was used on failed installation if thereās any
-The server/Plesk should be using PHP-FPM as application.
-And all files permission should be set to 755
My further response:
Thanks for the updateā¦ engineers points noted with my comments:
I may not have established a totally new DB clear of historical settings, but I did delete any old DB and try a new DB myself.
I am using Dedicated FPM app served by Apache.
I have noted that there are references to 755 permissions in the ConcreteCMS installation notes. I have ignored these in the past when installing earlier versions of Concrete and have assumed that 1stdomains have these requirements set by default. It seems confusing to me that the Concrete manual installation instructions include Apache CLI type instructions like chmod -R 777 files /*.
Thank you for taking the time to post more detail. Iād defer judgement to other users who know Linux permissions better than I, but I agreeā¦,
āset the apache user (either āapacheā or ānobodyā) as having full rights to these file. If neither are possible, chmod 777 to files/ and all items within (e.g. : chmod -R 777 files/* )ā
Note: no space between āfilesā and "/" in the directions. Sometimes using the -v (verbose) option for chmod is helpful to verify that itās doing what you expected.
ā¦ seems like something that should be used as a last resort, if thatās what you mean by āconfusingā. Iāve never encountered a problem with user permissions when installing via the downloaded compressed version (vs. Composer). I think setting the users to (āapacheā or ānobodyā) may be an important aspect when resorting to chmod -R 777.
Thanks for your follow up.
The ConcreteCMS Installtion link shows the reference to Linux SU commands which I find confusing especially as I donāt know Linux. I did look at all the manually installed extracted files R/W settings to see that R/W settings were enabled but the āWorld Writableā requirements must be deeper inside the hostās Linux system.
Anyway I have 9.2.0 up and running and I am rebuilding my website.
