Berikut adalah panduan ringkas untuk membuat dashboard tabel pemantau (All-in-One) agar Anda bisa melihat status CPU, RAM, dan Uptime dari semua server sekaligus dalam satu layar tanpa perlu klik satu per satu.

1. Persiapan Host

Pastikan semua server (Windows/Linux) sudah terdaftar di menu Data Collection > Hosts dan indikator ZBX sudah berwarna Hijau.

2. Membuat Dashboard Baru

1. Buka menu Dashboards (menu paling atas di sidebar).

2. Klik tombol Create dashboard di pojok kanan atas.

3. Beri nama, contoh: Monitoring Center, lalu klik Apply.

3. Menambahkan Widget Tabel (Top Hosts)

1. Klik Add widget di tengah layar atau pojok kanan atas.

2. Pilih Type: Top hosts.

3. Pada bagian Hosts, pilih grup server Anda atau masukkan nama host satu per satu (seperti rs, server-windows, dsb).

4. Konfigurasi Kolom (Inti Tabel)

Klik tombol Add pada bagian Columns untuk setiap data yang ingin ditampilkan:

Nama Kolom	Data / Item	Catatan
Host	Host name	Menampilkan nama server.
IP Address	Host interface	Menampilkan IP server secara otomatis.
CPU	Item value: CPU utilization	Menampilkan beban prosesor dalam %.
RAM	Item value: Memory utilization	Menampilkan penggunaan RAM dalam %.
Uptime	Item value: System uptime	Menampilkan durasi server menyala.

5. Simpan dan Selesai

export import mysql di podman ubuntu server

 

1. Skrip Export (export_volume.sh)

Gunakan ini di server asal untuk membungkus folder data.

Bash

#!/bin/bash
CONTAINER_NAME="psmysql"
DB_DATA_DIR="$HOME/mysql"
BACKUP_DIR="$HOME/volume_backup"
TIMESTAMP=$(date +%Y%m%d_%H%M%S)

# Buat folder backup jika belum ada
[[ ! -d "$BACKUP_DIR" ]] && mkdir -p "$BACKUP_DIR"

echo "📦 Archiving volume dari $DB_DATA_DIR..."
podman unshare tar -czf "$BACKUP_DIR/psmysql_$TIMESTAMP.tar.gz" -C "$DB_DATA_DIR" .

echo "✅ Selesai: $BACKUP_DIR/psmysql_$TIMESTAMP.tar.gz"

2. Skrip Import (import_volume.sh)

Gunakan ini di server tujuan untuk mengekstrak data.

Bash

#!/bin/bash
DB_DATA_DIR="$HOME/mysql"
BACKUP_DIR="$HOME/volume_backup"

# Cari file terbaru
LATEST_BACKUP=$(ls -t $BACKUP_DIR/*.tar.gz 2>/dev/null | head -1)

if [[ -z "$LATEST_BACKUP" ]]; then
    echo "❌ File backup tidak ditemukan di $BACKUP_DIR"; exit 1
fi

echo "📦 Import file: $(basename $LATEST_BACKUP)"
read -p "Lanjutkan? (y/n): " CONFIRM
[[ $CONFIRM != "y" ]] && exit 0

# Eksekusi
rm -rf "$DB_DATA_DIR" && mkdir -p "$DB_DATA_DIR"
podman unshare tar -xzvf "$LATEST_BACKUP" -C "$DB_DATA_DIR"
podman unshare chown -R 1001:1001 "$DB_DATA_DIR"

echo "✅ Import selesai. Silakan jalankan startmysql.sh"

podman mysql 8 percona di ubuntu server

 

🚀 Panduan Portabel Percona 8.0 (Podman)

1. Script: startmysql.sh (Tanpa InnoDB Config)

Gunakan $USER agar script otomatis mengenali siapa pun yang menjalankan script ini.

Bash

#!/bin/bash
# Nama File: startmysql.sh

CONTAINER_NAME="psmysql"
# Menggunakan $HOME agar otomatis menyesuaikan nama user server
DB_DATA_DIR="$HOME/mysql"
IMAGE_NAME="docker.io/percona/percona-server:8.0.44"

echo "--- Menjalankan Percona Server ---"

# Inisialisasi folder
mkdir -p "$DB_DATA_DIR"
# Paksa UID 1001 (default Percona) tanpa perlu tahu nama user host
podman unshare chown -R 1001:1001 "$DB_DATA_DIR"

podman rm -f $CONTAINER_NAME >/dev/null 2>&1 || true

podman run -d \
    --name $CONTAINER_NAME \
    --restart unless-stopped \
    -p 3306:3306 \
    -v "$DB_DATA_DIR":/var/lib/mysql:Z \
    -e TZ=Asia/Jakarta \
    -e MYSQL_ROOT_PASSWORD="SecretRootPassword" \
    -e MYSQL_ROOT_HOST="%" \
    $IMAGE_NAME \
    --max_connections=151 \
    --default-authentication-plugin=mysql_native_password \
    --sql-mode="" \
    --innodb_strict_mode=OFF \
    --character-set-server=utf8mb4 \
    --collation-server=utf8mb4_general_ci \
    --default-time-zone="+07:00"

echo "✅ Database berhasil dijalankan di $DB_DATA_DIR"

---

2. Script: startbackup.sh (Universal)

Menggunakan variabel $HOME dan $USER agar tidak gagal saat pindah server.

Bash

#!/bin/bash
# Nama File: startbackup.sh

CONTAINER_NAME="psmysql"
DATA_DIR="$HOME/mysql"
BACKUP_BASE_DIR="$HOME/backups"
TIMESTAMP=$(date +"%Y-%m-%d_%H-%M-%S")
TARGET_DIR="/backups/backup_$TIMESTAMP"

mkdir -p "$BACKUP_BASE_DIR"
# Memberikan izin ke container tanpa hardcode nama user
podman unshare chown -R 1001:1001 "$BACKUP_BASE_DIR"

echo "--- Memulai Backup Fisik ---"
podman run --rm \
    --network container:$CONTAINER_NAME \
    -v "$DATA_DIR":/var/lib/mysql:ro,Z \
    -v "$BACKUP_BASE_DIR":/backups:z \
    docker.io/percona/percona-xtrabackup:8.0 \
    xtrabackup --backup \
        --host=127.0.0.1 \
        --user=root \
        --password="SecretRootPassword" \
        --target-dir="$TARGET_DIR"

# Kembalikan akses ke user yang sedang login saat ini
sudo chown -R $USER:$USER "$BACKUP_BASE_DIR"
echo "✅ Backup selesai: $BACKUP_BASE_DIR/backup_$TIMESTAMP"

---

3. Script: startrestore.sh (Solusi Error 13)

Ini adalah versi yang memperbaiki error pada gambar Anda dengan menggunakan sudo chown -R $USER:$USER agar tidak peduli siapa nama user-nya.

Bash

#!/bin/bash
# Nama File: startrestore.sh
set -e

CONTAINER_NAME="psmysql"
DATA_DIR="$HOME/mysql"
BACKUP_BASE_DIR="$HOME/backups"
IMAGE_XTRABACKUP="docker.io/percona/percona-xtrabackup:8.0"

echo "--- Proses Restore Database ---"

# Pilih folder backup
cd "$BACKUP_BASE_DIR"
PS3="Pilih nomor folder backup: "
select SELECTED in *; do
    if [ -n "$SELECTED" ]; then
        FULL_PATH="$BACKUP_BASE_DIR/$SELECTED"
        break
    fi
done

# SOLUSI ERROR 13: Ambil alih kepemilikan folder secara universal
sudo chown -R $USER:$USER "$FULL_PATH"
sudo chmod -R 777 "$FULL_PATH"

echo "1. Prepare Data (Applying Logs)..."
# Gunakan user 0:0 agar xtrabackup bisa mkdir #innodb_redo di dalam container
podman run --rm --user 0:0 -v "$FULL_PATH:/backup:rw,z" $IMAGE_XTRABACKUP \
    xtrabackup --prepare --target-dir=/backup

echo "2. Cleanup & Copy-back..."
podman rm -f $CONTAINER_NAME >/dev/null 2>&1 || true
sudo rm -rf "$DATA_DIR"
mkdir -p "$DATA_DIR"

podman run --rm --user 0:0 \
    -v "$FULL_PATH:/backup:ro,z" \
    -v "$DATA_DIR":/var/lib/mysql:rw,z \
    $IMAGE_XTRABACKUP \
    xtrabackup --copy-back --target-dir=/backup --datadir=/var/lib/mysql

# Final Touch: Set izin ke UID 1001 agar Percona bisa start
podman unshare chown -R 1001:1001 "$DATA_DIR"

echo "✅ Restore selesai. Sekarang jalankan ./startmysql.sh"

exec di ubuntu server

# buat file
nano /home/rs/start-mysql.sh

#!/bin/bash
cd /home/rs/podman/db_percona || exit 1
/usr/bin/podman compose up -d

# jadikan executable
chmod +x /home/rs/start-mysql.sh

# jalankan

Backup & Restore Docker Image Percona (Image Only)

Backup Image

Ukuran file .tar lebih kecil dari size image di Docker → NORMAL.

docker save percona/percona-server:8.0.44 -o percona_8.0.44.tar

Hasil:

• File ±300–600 MB (compressed)

• Image di Docker ±2 GB (uncompressed)

---

Hapus Image

docker rmi percona/percona-server:8.0.44

---

Restore Image

docker load -i percona_8.0.44.tar

---

Verifikasi

docker images

Image percona/percona-server:8.0.44 muncul kembali → restore sukses

docker awal

 

Docker Praktis (Versi Ringkas)

Di mana buka PowerShell?

Buka PowerShell di folder yang ada docker-compose.yml

Contoh:

C:\docker\app
 └─ docker-compose.yml

Cara cepat:

• Buka folder → klik kanan → Open in Terminal

• Atau:

cd C:\docker\app

---

Perintah Utama Docker

Jalankan aplikasi

docker compose up -d

Hentikan aplikasi

docker compose down

---

Command Wajib Dihafal

docker ps
docker compose up -d
docker compose down
docker logs <nama_container>
docker rm -f <nama_container>

---

Catatan Penting

• Jangan jalankan Docker dari folder sembarang

• Satu aplikasi = satu folder

• Semua perubahan lewat docker-compose.yml

Reuse Datastore PBS Lama di iSCSI

 

Rekap: Reuse Datastore PBS Lama di iSCSI (Tanpa Hilang Data)

Kasus
PBS baru, iSCSI lama berisi datastore PBS sebelumnya, data tidak boleh hilang.

---

1. Login iSCSI

apt install open-iscsi -y
iscsiadm -m discovery -t sendtargets -p 193.168.10.19
iscsiadm -m node --login

Pastikan disk muncul (/dev/sdb).

---

2. Mount iSCSI (cek isi)

mount /dev/sdb /mnt/pbs
ls -la /mnt/pbs

Jika terlihat struktur seperti:

.chunks
.lock
.gc-status
vm

→ itu datastore PBS lama (VALID).

---

3. Daftarkan datastore EXISTING (UI & CLI akan gagal)

UI/CLI menolak karena path tidak kosong (by design).

Solusi resmi: edit config langsung

nano /etc/proxmox-backup/datastore.cfg

Isi:

datastore: nas-backup-19
        path /mnt/pbs

Restart service:

systemctl restart proxmox-backup
systemctl restart proxmox-backup-proxy

Datastore lama langsung muncul di UI.

---

4. Buat mount iSCSI permanen

Ambil UUID:

blkid /dev/sdb

Edit /etc/fstab:

UUID=xxxx  /mnt/pbs  xfs  _netdev,noatime  0  2

Reload:

systemctl daemon-reload

Aktifkan auto-login iSCSI:

iscsiadm -m node -p 193.168.10.19 --op update -n node.startup -v automatic

---

5. Tes final (reboot)

reboot
mount | grep /mnt/pbs

Jika masih ter-mount → PERMANEN & AMAN.
