how can i fix this situation ?

Another questions is there a way to automate the installation of percona packages via ansible ?

Because it seems there is no way to do it.

thanks in advance

Hi @soprano!
In your case PXC is not installed.
You need to try apt install --fix-broken command and resolve the issue.
I tried to reproduce it on my end but without success,
In my case all packages were installed correctly

Is there a way to bootstrap the cluster from ubuntu ?

i tried with

root@XXXXX:~# systemctl start mysql@bootstrap
Failed to start mysql@bootstrap.service: Unit mysql@bootstrap.service not found.

root@XXXXX:~# systemctl start mysql.service@bootstrap
Failed to start mysql@bootstrap.service: Unit mysql@bootstrap.service not found.

only

root@XXXXX:~# /etc/init.d/mysql bootstrap-pxc

fail

I think there is something not working with the installation process

Any hint/help is welcome

Hi @soprano
Seems you have enabled apparmor on your system.
In order to use PXC it is needed to disable it.
As for bootstraping node: /etc/init.d/mysql bootstrap-pxc
You can find more information in our documentation: Bootstrapping the First Node - Percona XtraDB Cluster

Thanks for the suggestion, but

i removed apparmor with

Maybe i have to remove all the files info in /var/lib/mysql before reinstall mysql ?

EDIT: i uninstalled, purged, removed all the files in /var/lib/mysql, then reinstalled percona, same error

I was expecting that the instalation finish with no error and mysql start as single node/mysql server but this is not the case

soprano · December 16, 2021, 2:22pm

the problem seems this

2021-12-16T14:13:33.858029Z 0 [ERROR] Fatal error: Can't open and lock privilege tables: Table 'mysql.user' doesn't exist
2021-12-16T14:13:33.858036Z 0 [ERROR] Fatal error: Failed to initialize ACL/grant/time zones structures or failed to remove temporary table files.
2021-12-16T14:13:33.858057Z 0 [ERROR] Aborting

infact in /var/lib/mysql there is not a mysql directory with the user table files

so during installation it would be create, right ?

this is the list of the /var/lib/mysql directory

the db and binarylogs directories will be used in when i will configure the cluster, the first will keep the db files, the second the binarylogs, but for now they are not used

Claudio

soprano · December 17, 2021, 1:36pm

I didn’t write this, i used the percona-release_latest.generic_all.deb package how in the guide, maybe is this the problem ?

Someone has any hint ?

Claudio

soprano · December 22, 2021, 10:23am

Does someone know a way to check what the installation script does ?

Where do i find the installation script for percona-xtradb-cluster-57 ?

I suspect something is wrong in the installation script or in my ubuntu installation.

Thanks in advance
Claudio

soprano · January 3, 2022, 10:51am

No one can give some hints ?

I’m stuck with the installation of this Percona XtraDB Cluster on 3 Ubuntu LTS 20.04 nodes

Claudio

Evgeniy_Patlan · January 3, 2022, 11:04am

Hi @soprano
I tried to reproduce your issue but without any success,
I am able to install PXC-5.7 on Ubuntu without any issues.
Here is the detailed installation instruction Installing Percona XtraDB Cluster on Debian or Ubuntu - Percona XtraDB Cluster
And it should work.
I followed it and was able to install PXC correctly

soprano · January 3, 2022, 11:30am

I found why it gives errors.

I have the /var/lib/mysql

but inside it i have two directories:

db
binarylogs

both are on another disk, different volume group, different logical volumes, both are owned by mysql:mysql

/etc/fstab
/dev/mysql/db   /var/lib/mysql/db       xfs     defaults        0       1
/dev/mysql/binarylogs   /var/lib/mysql/binarylogs       xfs     defaults        0       2

ll /var/lib/mysql

if i umount both these directories and install percona all is ok.

while if i mount these directories the installation fails

You can reproduce this error, i suppose something in the installation try to removes all the files in the /var/lib/mysql but fails (it is not possible to remove directories mounted on other disks).

I use these directories, because i set

the DB dir to /var/lib/mysql/db
the binarylogs to /var/lib/mysql/binarylogs
the relaylogs to /var/lib/mysql/relaylogs (if i have slaves)
i have to do so, because if db are in /var/lib/mysql directory and binarylogs/relaylogs inside it then SST will not work if the node goes down, because the binarylogs directory will be deleted before SST begins.

How can i solve this ?

Let me know if you need other infos.

naresh49kumar · January 4, 2022, 5:47am

I’m new to proxysql. I’ve installed proxysql on one server and configured 2 nodes in it in mysql_servers.
proxysql is up and running but when I’m connecting to 6033 port with sbuser which I created under the mysql_users table, it is throwing access denied error.

[root@server19 proxysql]# mysql -u sbuser -psbpass -h 127.0.0.1 -P6033
ERROR 2003 (HY000): Can’t connect to MySQL server on ‘127.0.0.1’ (111)

Where should I debug?

soprano · January 4, 2022, 7:59am

Ok i solved modifyng the file

/etc/mysql/percona-xtradb-cluster.conf.d/mysqld.cnf
..
datadir=/var/lib/mysql/db
..

in this way the percona installation will finish good using apt install --fix-broken

So the problem is with mountpoints and FS mounted under /var/lib/mysql/

I suppose because during the first start of mysql, the /var/lib/mysql directory is erased to prevent bogus files and in my case it is not possible (for the mountpoints linked to different volume FS)

Claudio

soprano · January 4, 2022, 8:18am

You need to post this problem to a new topic else it will not be visible for that it is.

Claudio

naresh49kumar · January 4, 2022, 8:31am

ok. But I’ve installed proxysql manually using rpm of proxysql.

soprano · January 4, 2022, 8:51am

Repeat,

it’s better to open a new topic and not to write on this one, this is about Percona xtradb cluster 57 installation and configuration problems and not proxysql.

If you open a new topic you will get better support.

If you are trying to connect proxysql to a Percona Xtradb Cluster 57, you can write in this forum section else you will have to choose the right forum section, anyway a new topic is always a better solution for different problems on different products.

naresh49kumar · January 4, 2022, 8:54am

yeah got that. I just wrote to inform you.
Already opened a new topic on this.

Thank you so much.

soprano · January 4, 2022, 8:55am

Perfect.

You will get support as soon as someone knows how to help you
