almost from mariadb
http://teguhth.blogspot.com/2023/06/enabling-gtids-replication-in-mariadb.html

A. Configure GTID Replica MySQL 8
1. install mysql8 on server01 & server02
http://teguhth.blogspot.com/2023/07/how-to-install-mysql-8-on-centos-7.html

2. configure in server01 & restart mysql

server_id = 1          # Unique ID for the primary server
log-bin = mysql-bin    # Binary log file name prefix
binlog_format = mixed  # Mixed format allows GTIDs
gtid_mode = ON         # Enable GTID mode
enforce_gtid_consistency = true
slave-skip-errors=1062,1032

[root@teguhth01 ~]# cat /etc/my.cnf
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/8.0/en/server-configuration-defaults.html
 
[mysqld]
#.........

datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock

log-error=/var/lib/mysql/mysql_error.log
pid-file=/var/run/mysqld/mysqld.pid

server_id = 1          # Unique ID for the primary server
log-bin = mysql-bin    # Binary log file name prefix
binlog_format = mixed  # Mixed format allows GTIDs
gtid_mode = ON         # Enable GTID mode
enforce_gtid_consistency = true
slave-skip-errors=1062,1032

default_authentication_plugin=mysql_native_password
[root@teguhth01 ~]#

[root@teguhth01 ~]# systemctl restart mysqld
[root@teguhth01 ~]#

3. configure in server02 & restart mysql

server_id = 2          # Unique ID for the primary server
log-bin = mysql-bin    # Binary log file name prefix
binlog_format = mixed  # Mixed format allows GTIDs
gtid_mode = ON         # Enable GTID mode
enforce_gtid_consistency = true
slave-skip-errors=1062,1032

[root@teguhth02 ~]# cat /etc/my.cnf
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/8.0/en/server-configuration-defaults.html

[mysqld]
#..........
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock

log-error=/var/lib/mysql/mysql_error.log
pid-file=/var/run/mysqld/mysqld.pid

server_id = 2          # Unique ID for the primary server
log-bin = mysql-bin    # Binary log file name prefix
binlog_format = mixed  # Mixed format allows GTIDs
gtid_mode = ON         # Enable GTID mode
enforce_gtid_consistency = true

slave-skip-errors=1062,1032
default_authentication_plugin=mysql_native_password

[root@teguhth02 ~]#
[root@teguhth02 ~]# systemctl restart mysqld
[root@teguhth02 ~]#

4. create user replica for server01 and for server02<optional cause mirroring >

CREATE USER 'replica'@'%' IDENTIFIED BY 'password';
GRANT REPLICATION SLAVE ON *.* TO 'replica'@'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;

GRANT ALL PRIVILEGES ON  *.* TO 'replica'@'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;

5. check master status

reset master;
show master status;


mysql> select @@hostname,@@version;
+------------+-----------+
| @@hostname | @@version |
+------------+-----------+
| teguhth01  | 8.0.34    |
+------------+-----------+
1 row in set (0.00 sec)

mysql> reset master;
Query OK, 0 rows affected (0.01 sec)

mysql> show master status;
+------------------+----------+--------------+------------------+-------------------+
| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+-------------------+
| mysql-bin.000001 |      157 |              |                  |                   |
+------------------+----------+--------------+------------------+-------------------+
1 row in set (0.00 sec)

mysql>
 

6. check reset slave
reset slave all;
show slave status \G;

mysql> select @@hostname,@@version;
+------------+-----------+
| @@hostname | @@version |
+------------+-----------+
| teguhth02  | 8.0.34    |
+------------+-----------+
1 row in set (0.00 sec)

mysql> reset slave all;
Query OK, 0 rows affected, 1 warning (0.01 sec)

mysql> show slave status \G;
Empty set, 1 warning (0.00 sec)

ERROR:
No query specified

mysql>
 

6. backup all database on server01

mysqldump -h teguhth01 -uroot -proot -CfQq --max-allowed-packet=1G --hex-blob --order-by-primary --set-gtid-purged=OFF --single-transaction --routines=true --triggers=true --no-data=false  --all-databases > alldbdb.sql;

[root@teguhth02 data]# mysqldump -h teguhth01 -uroot -p -CfQq --max-allowed-packet=1G --hex-blob --order-by-primary --set-gtid-purged=OFF --single-transaction --routines=true --triggers=true --no-data=false  --all-databases > alldbdb.sql;
WARNING: --compress is deprecated and will be removed in a future version. Use --compression-algorithms instead.
Enter password:
[root@teguhth02 data]#
[root@teguhth02 data]# ls
alldbdb.sql  fullall.sh  fullbackupsimple.sh  mysql80-community-release-el7-7.noarch.rpm  simplerestore.sh
 

7. restore to server02

mysql -uroot -p -f < alldbdb.sql

[root@teguhth02 data]# mysql -uroot -p -f < alldbdb.sql
Enter password:
[root@teguhth02 data]#

8. configure set master to master on server02

select @@hostname,@@version;
stop slave ; reset slave; reset master;
CHANGE MASTER TO MASTER_HOST='10.10.10.61',MASTER_PORT=3306 ,MASTER_USER='root', MASTER_PASSWORD='root', MASTER_AUTO_POSITION = 1;
start slave;
show slave status \G;

mysql> stop slave ; reset slave; reset master;
Query OK, 0 rows affected, 2 warnings (0.00 sec)

Query OK, 0 rows affected, 1 warning (0.00 sec)

Query OK, 0 rows affected (0.01 sec)

mysql> CHANGE MASTER TO MASTER_HOST='10.10.10.61',MASTER_PORT=3306 ,MASTER_USER='root', MASTER_PASSWORD='root', MASTER_AUTO_POSITION = 1;
Query OK, 0 rows affected, 8 warnings (0.01 sec)

ERROR:
No query specified

mysql> start slave;
Query OK, 0 rows affected, 1 warning (0.05 sec)

mysql>
 

9. check slave status
mysql> show slave status \G;

B. testing
1. check from server02 & server02 before testing

select @@hostname,@@version;
show databases;
use teguhth;
show tables;
select * from teguhth.barang;
 

 

2. create database, create tavle & insert table barang on server01

create database teguhth;
use teguhth;

create table barang(KODE_BARANG char(6) not null ,NAMA_BARANG varchar(25),SATUAN_BARANG varchar(20),STOK_BARANG decimal(4),primary key (KODE_BARANG));

select @@hostname,@@version,KODE_BARANG,NAMA_BARANG,SATUAN_BARANG,STOK_BARANG from barang;
insert into barang(KODE_BARANG,NAMA_BARANG,SATUAN_BARANG,STOK_BARANG) values('ELK-01','RICE COOKER','BUAH',20);
insert into barang(KODE_BARANG,NAMA_BARANG,SATUAN_BARANG,STOK_BARANG) values('ELK-02','LEMARI ES','UNIT',8);
insert into barang(KODE_BARANG,NAMA_BARANG,SATUAN_BARANG,STOK_BARANG) values('ELK-03','TELEVISI','UNIT',30);
insert into barang(KODE_BARANG,NAMA_BARANG,SATUAN_BARANG,STOK_BARANG) values('ELK-04','RADIO/TAPE','BUAH',35);
insert into barang(KODE_BARANG,NAMA_BARANG,SATUAN_BARANG,STOK_BARANG) values('ELK-05','KOMPUTER','UNIT',28);
insert into barang(KODE_BARANG,NAMA_BARANG,SATUAN_BARANG,STOK_BARANG) values('ELK-06','KIPAS ANGIN','BUAH',38);
select @@hostname,@@version,KODE_BARANG,NAMA_BARANG,SATUAN_BARANG,STOK_BARANG from barang;
 

4. check from server01 & server02 after testing

select @@hostname,@@version;
show databases;
use teguhth;
show tables;
select @@hostname,@@version,KODE_BARANG,NAMA_BARANG,SATUAN_BARANG,STOK_BARANG from barang;
