Description
Today I performed testing on Galera Clustering with MariaDB 10.3.10. I have 3-node cluster.
I updated the server.cnf with the following statement:
wsrep_on=OFF
I restarted mysql by ...
- systemctl stop mysql
- systemctl sart mysql
It worked.
wsrep_cluster_status = Disconnected

|
|
MariaDB [(none)]> SHOW global variables LIKE 'wsrep_on%';
|
+---------------+-------+
|
| Variable_name | Value |
|
+---------------+-------+
|
| wsrep_on | OFF |
|
+---------------+-------+
|
Then I typed the following command to change wsrep_on to ON:
MariaDB [(none)]> set global wsrep_on = ON;
|
|
|
MariaDB [(none)]> SHOW global variables LIKE 'wsrep_on%';
|
+---------------+-------+
|
| Variable_name | Value |
|
+---------------+-------+
|
| wsrep_on | ON |
|
+---------------+-------+
|
1 row in set (0.002 sec)
|
Then, MariaDB was DEAD!
- ps -ef|grep mysql

Here attached is the error log file.
