Wordpress on Vultr 768

Have you checked to see if these files exist and are correct size? Have you checked the .cnf file
InnoDB: Error: log file ./ib_logfile0 is of different size 0 5242880 bytes
InnoDB: than specified in the .cnf file 0 8388608 bytes!

Check your cnf file to see that it is correct. Rename/move ib_logfile0, ib_logfile1 (they'll get recreated when the service starts again)

I renamed and started the service again, and the files were re-created. The site is online for a few seconds then crashes again. I'm not seeing any configuration file other than /etc/my.cnf, and the file only has a few lines of code in it.

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd

[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid

#
# include all files from the config directory
#
!includedir /etc/my.cnf.d

The files in /etc/my.cnf.d have almost nothing in them as well.

@scottalanmiller Yeah, that didn't fix it. I'll just start over. I recall discussion on here previously that the "one click" installs of Wordpress on Vultr are not recommended. I couldn't remember (or find the discussion) why this was the opinion...

That's correct, those are never recommended. Use the OS, not a third party system.

I think there should be a bit more lines in that file.
What size files are the recreated innodb files?
What is the contents of /var/log/mariadb/mariadb.log

5242880 bytes is the size of the new files.

Seems like I'm in a time warp, as it is warning me that my sequence numbers are in the future!

So following the directions to force innodb into recovery mode, the DB starts, but then the logs say this:

Just a bit of browsing I find this. You do actually seem to be out of memory, try adding

performance_schema = off

to the [mysqld] section of my.cnf

No go. Same result, same errors

AdamF

Oh look, I fixed it!
(throws hands up and reinstalls.)

dafyre

Just don't forget to feed it... water it... say nurturing things to it.

momurda

Ah I forgot you put it in recovery mode. Turning that off might have fixed it, but if youre going to NIFO then that is ok too. Also when doing the reinstall make sure your permissions are right.

scottalanmiller

Wait, it works now? Or you reinstalled? Or both?

Sounds like both.

momurda

Think he means he fixed it by 'throwing hands up' and reinstalling. DOes the reinstall work though?

AdamF

I "fixed it" by reinstalling. Now I'm in the process of setting up LAMP and then Wordpress again.

Gotcha

dafyre

It's the old "Take that!" & nuke it from orbit ploy. Works every time.

AdamF

@dafyre Exactly. Didn't want to waste any more time on it, especially since it was still in testing/setup stages.

Makes sense.

@thwr said in Wordpress on Vultr 768:

Most Wordpress sites only have like 128 MB, maybe 256 MB.

I doubt that most do, as it's effectively impossible for many years to even get VPS that small. Rackspace minimum is 512MB and DO/Vultr is like 768MB.

I wasn't sure what he got at that point. Wordpress runs "fine" on 128MB, but that does not take into account what the operating system, Apache/Nginx and MySQL need.

A VM with Wordpress and a full webserver/database server stack should probably have like 512 MB at least.

It should run fine on 16MB then

For any real use, yeah. We have it working on 256MB, but it sucks.
