Create and setup a Maria DB in node 1. | |||||||||
Configure Maria DB to generate binary log files. Add the following lines to /etc/mysql/my.cnf: server-id = 1 | |||||||||
Restart MariaDB: service mysql restart |

Create and setup a Maria DB in node 2. | |||||||||
Configure Maria DB to generate binary log files. Add the following lines to /etc/mysql/my.conf: server-id = 2 | |||||||||
Restart MariaDB: service mysql restart | |||||||||
Create a user for node 1 to fetch data from node 2. From mysql, execute: grant replication slave on *.* to replication_user@<NODE1-IP> set password for replication_user@1<NODE1-IP> = password('<NODE1-PASS>') | |||||||||
Create a user for node 2 to fetch data from node 1. From mysql, execute: grant replication slave on *.* to replication_user@<NODE2-IP> set password for replication_user@1<NODE2-IP> = password('<NODE2-PASS>') | |||||||||
Query current binary log position: MariaDB [(none)]> show master status; The result should look like this:
The got values will be used on node 2 to start replica process. | |||||||||
Start replication from node 1 to node 2. From mysql, execute the following sentence, replacing proper values: CHANGE MASTER TO | |||||||||
Verify replica is working right, by executing SHOW SLAVE STATUS \G Check following lines: Slave_IO_Running: Yes | |||||||||
Query current binary log position: MariaDB [(none)]> show master status; The result should look like this:
The got values will be used on node 1 to start replica process. | |||||||||
Now, start replication from node 2 to node 1. From mysql, execute the following sentence, replacing proper values: CHANGE MASTER TO | |||||||||
Verify replica is working right, by executing SHOW SLAVE STATUS \G Check following lines: Slave_IO_Running: Yes |
| ||||||||
Now, create and start SC_SEQUENCE table in node 1. This sequence will generate values 1, 11, 21, 31, 41, and so on: CREATE TABLE `SC_SEQUENCE` ( INSERT INTO SC_SEQUENCE VALUES (1, 100, 10); | |||||||||
Now, create and start SC_SEQUENCE table in node 2. This sequence will generate values 2, 12, 22, 32, 42, and so on:: CREATE TABLE `SC_SEQUENCE` ( INSERT INTO SC_SEQUENCE VALUES (2, 100, 10); | |||||||||
Now, install heartbeat to create a floating IP address to connect Soffid console to database. Create /etc/ha.d/ha.cf file: autojoin none | |||||||||
Create security token in node 1: ( echo -ne "auth 1\n1 sha1\n"; dd if=/dev/urandom bs=512 count=1 | openssl sha1 | cut --delimiter=' ' --fields=2 ) > /etc/ha.d/authkeys chmod 600 /etc/ha.d/authkeys
| |||||||||
Copy both files to node 2: /etc/ha.d/ha.cf and /etc/ha.d/authkeys | |||||||||
Restart heartbeat service | |||||||||

Add floating IP to the cluster: crm configure | |||||||||
Check floating IP is up and bound to node 1 |
