A. Configuring MySQL Server on Server01
1. Edit & add db file conf /etc/my.cnf
server_id=1
replicate-do-db=teguht
#bind-address=10.10.10.10
log-bin = mysql-bin
binlog_do_db = teguht
set global read_only=on;
set global read_only=off;
skip-slave-start
set global read_only=1;
======
[root@MariaDB002 ~]# cat /etc/my.cnf.d/server.cnf
## -> only 1 database (teguhth)
[mariadb]
server_id=1
replicate-do-db=teguhth
#bind-address=10.10.10.10
log-bin = mysql-bin
binlog_do_db = teguhth
## -> more 2 database (teguhth, secretdb, labdb)
[mariadb]
server_id=1
replicate-do-db=teguhth
replicate-do-db=secretdb
replicate-do-db=labdb
#bind-address=10.10.10.10
log-bin = mysql-bin
binlog_do_db = teguhth
binlog_do_db = secretdb
binlog_do_db = labdb
sample log
[root@teguht01 ~]# cat /etc/my.cnf
[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
server_id=1
replicate-do-db=teguht
#bind-address=10.10.10.10
log-bin = mysql-bin
binlog_do_db = teguht
relay-log = /var/lib/mysql/mysql-relay-bin
relay-log-index = /var/lib/mysql/mysql-relay-bin.index
log-error = /var/lib/mysql/mysql.err
master-info-file = /var/lib/mysql/mysql-master.info
relay-log-info-file = /var/lib/mysql/mysql-relay-log.info
log-bin = /var/lib/mysql/mysql-bin

#pid-file=/var/run/mariadb/mariadb.pid
#
# include all files from the config directory
#
!includedir /etc/my.cnf.d
[root@teguht01 ~]#
2. Log on to the MariaDB server01 as root, create the user slave and assign the necessary grants
create database teguht;
CREATE USER 'replica'@'localhost' IDENTIFIED BY 'password';
grant replication slave on *.* to replica@'%' identified by 'password';
flush privileges;
SHOW GRANTS FOR replica@'%';
exit
sample log
mysql> create database teguht;
mysql> CREATE USER 'replica'@'localhost' IDENTIFIED BY 'password';
mysql> grant replication slave on *.* to replica@'%' identified by 'password';
mysql> flush privileges;
mysql> SHOW GRANTS FOR replica@'%';
Mysql> exit
3. Log on to the MariaDB server as root, create the user slave and assign the necessary grants
show master status
mysql> show master status;
+------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |

| mysql-bin.000001 | 2511 | teguht | | |
+------------------+----------+--------------+------------------+-------------------+
1 row in set (0.00 sec)
mysql>
4. record master status on notepad from result output status server01
change master to master_host='10.10.10.20', master_user='replica', master_password='password', master_log_file='mysql-bin.000001', master_log_pos=2511;
5. Snapsot Database MySQL
set global read_only=on;
# mysqldump -u root -p teguht > /data/backup/teguht.sql
set global read_only=off;
6. Copied to server 2
# scp /data/backup/teguht.sql root@10.10.10.20:/root/
B. Configuring MySQL Server on Server02
1. Edit & add db file conf /etc/my.cnf
server_id=2
replicate-do-db=teguht
#bind-address=10.10.10.20
log-bin = mysql-bin
binlog_do_db = teguht
sample log
[root@teguht02 ~]# cat /etc/my.cnf
[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
server_id=2
replicate-do-db=teguht
#bind-address=10.10.10.20
log-bin = mysql-bin
binlog_do_db = teguht
relay-log = /var/lib/mysql/mysql-relay-bin
relay-log-index = /var/lib/mysql/mysql-relay-bin.index
log-error = /var/lib/mysql/mysql.err
master-info-file = /var/lib/mysql/mysql-master.info
relay-log-info-file = /var/lib/mysql/mysql-relay-log.info
log-bin = /var/lib/mysql/mysql-bin
skip-slave-start
[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
[root@teguht01 ~]#
2. Log on to the MariaDB server02 as root, create the user slave and assign the necessary grants
create database teguht;
CREATE USER 'replica'@'localhost' IDENTIFIED BY 'password';
grant replication slave on *.* to replica@'%' identified by 'password';
flush privileges;
SHOW GRANTS FOR replica@'%';
exit
sample log
mysql> create database teguht;
mysql> CREATE USER 'replica'@'localhost' IDENTIFIED BY 'password';
mysql> grant replication slave on *.* to replica@'%' identified by 'password';
mysql> flush privileges;
mysql> SHOW GRANTS FOR replica@'%';
Mysql> exit
3. Log on to the MariaDB server as root, create the user slave and assign the necessary grants
show master status
sample log
mysql> show master status;
+------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |

| mysql-bin.000002 | 2522 | teguht | | |
+------------------+----------+--------------+------------------+-------------------+
1 row in set (0.00 sec)
mysql>
4. record master status on notepad from result output status server02
change master to master_host='10.10.10.20', master_user='replica', master_password='password', master_log_file='mysql-bin.000002', master_log_pos=2522;
C. Set Master to Master On Server01 if you want to set Master to slave, donot do it
1. Set master to master status on MySQL Server01
stop slave;
change master to master_host='10.10.10.20', master_user='replica', master_password='password', master_log_file='mysql-bin.000002', master_log_pos=2522;
start slave;
SHOW SLAVE STATUS\G;
sample output
mysql> stop slave;
mysql> change master to master_host='10.10.10.20', master_user='replica', master_password='password', master_log_file='mysql-bin.000002', master_log_pos=2522;
mysql> start slave;
mysql> SHOW SLAVE STATUS\G;
2. Checking master status
