MariaDB Galera does not bootstrap the first node - mariadb

I have installed ubuntu 16.04 on a VMware VM. Then I added the repo from mariadb website and I installed the latest version of mariadb 10.1.
The installation works fine
I have then created a file
sudo nano /etc/mysql/conf.d/cluster.cnf
with the following
[mysqld]
# Cluster node configurations
wsrep_cluster_address="gcomm://20.0.1.51"
wsrep_node_address="20.0.1.51"
innodb_buffer_pool_size=800M
# Mandatory settings to enable Galera
wsrep_on=ON
wsrep_provider=/usr/lib/galera/libgalera_smm.so
binlog_format=ROW
default-storage-engine=InnoDB
innodb_autoinc_lock_mode=2
innodb_doublewrite=1
query_cache_size=0
bind-address=0.0.0.0
# Galera synchronisation configuration
wsrep_sst_method=rsync
I want only to bootstrap the first node and then add new nodes
So I run
sudo service mysql bootstrap
But I get this error

What am I doing wrong??

Its the systemd thing. On systems that has systemd, one should use galera_new_cluster to bootstrap a new cluster.

I don't know what happened. I also try
mysqlcheck
root#vps45223599:/var/log# mysqlcheck --all-databases -p
Enter password:
mysqlcheck: Got error: 2002: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2 "No such file or directory") when trying to connect
I don't know what else I should try, can anyone helpe me, please?
Cheers
As #obe said this is likely a proxmox or whatever is instigating systemd without sufficient privileges is the issue.
The devices.allow error is probably requested by the PrivateDevices=true (seems confirmed based on MDEV-13207 which failed to provide more info) aspect of the systemd service file for MariaDB.
PrivateDevices=true allows:
/dev/null
/dev/zero
/dev/random
Based on this answer for a different device, doing the equivalent for these devices would be:
lxc config set mycontainer raw.lxc 'lxc.cgroup.devices.allow = c 1:3 rwm'
lxc config set mycontainer raw.lxc 'lxc.cgroup.devices.allow = c 1:8 rwm'
lxc config set mycontainer raw.lxc 'lxc.cgroup.devices.allow = c 1:5 rwm'
Major/minor device code determined by:
$ ls -la /dev/zero /dev/random /dev/null
crw-rw-rw-. 1 root root 1, 3 Jan 8 22:20 /dev/null
crw-rw-rw-. 1 root root 1, 8 Jan 8 22:20 /dev/random
crw-rw-rw-. 1 root root 1, 5 Jan 8 22:20 /dev/zero
Thanks all for the answer.
#danblack Nothing change, suddenly stop working, but reading this forum I found the solution in this thread.
Can't start MariaDB on debian 10
Basically the solution is ...
"Solved it by deleting/renaming the tc.log mv -vi /var/lib/mysql/tc.log /root And restarting the database service mysql restart"
And mariaddb start again.

Why can't I start MariaDB?

Arch Linux, standard kernel 5.16.3, MariaDB v10.6.5.
I try to start MariaDB, and it fails with

So okay, I can't connect because the server isn't starting up. But even when it did start --- it did start on a few occasions, I would still get this error. I looked in /run/mysqld, and mysqld.sock is there, with 777 permissions, and it's owned by the mysql user. I've also made sure that /var/lib/mysql and everything underneath it is owned by mysql
Here's /etc/my.cnf
#
# This group is read both by the client and the server
# use it for options that affect everything
#
[client-server]
[mysqld]
socket = /run/mysqld/mysqld.sock
[client]
socket = /run/mysqld/mysqld.sock
#
# include *.cnf from the config directory
#
!includedir /etc/my.cnf.d
What are the next possible steps? I've scoured the 'net, and nothing seems to help.
When initializing the database, mysql_install_db Whether the datadir directory is specified during dB. It is recommended to use my.cnf Specify the datadir directory in the CNF configuration file
Okay, so Paul T's comment
Curious about the two missing tables causing errors. Did the install not go smoothly, maybe reinstall?
was the clue. Looked at the MariaDB page on the Arch wiki, and I forgot to run mariadb-install-db. Should've RTFM.

OpenStack Keystone Identity Service Httpd Failed (rocky version)

Hello and thanks for taking some of your time to check my problem
i'm following the detailed steps by openstack to install openstack in no avail (https://docs.openstack.org/keystone/rocky/install/keystone-install-rdo.html)

If you would be able to provide me with a solution to this, it would be much appreciated.
Event if MAMP quits, sometimes MySQL is running in the background. Could you kill all MySQL background process and try again?
Quit MAMP
Open the terminal and type: killall -9 mysqld
Restart MAMP
