.::: How to Create HA (High Availability) MariaDB/MySQL uting Galera Cluster on Linux (Include trouble shoot Crash case :::.

A. Installation Galera Cluster (example on 3 node = node1, node2, node3)
1. Disable selinux
[root@teguhth01 ~]# sestatus
SELinux status:                 disabled
[root@teguhth01 ~]# cat /etc/selinux/config 
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

.::: Create Stored Procedure & Function Using SQL Server (Sample database moonton Mobile Legend) :::.

Stored Procedure

Stored Procedure merupakan sekumpulan perintah-perintah SQL yang tersimpan dengan nama tertentu dan diproses sebagai sebuah kesatuan. Bisa diakatan sebuah sub program yang tersimpan di database.

Membuat Function

Function adalah suatu blok SQL yang memiliki konsep sama dengan procedure, hanya saja pada function terdapat pengembalian nilai (return value)

A. Create database
create database mobile_legend
go

.::: Basic Store Procedure SQL Server :::.

1. Sample 1
-- SQL Query 1
select kode_barang, stok_barang from barang;

-- Store Procedure 1
create procedure kodestokbarang 
as 
select kode_barang, stok_barang from barang;
