Server Percona untuk MongoDB adalah distribusi sumber terbuka MongoDB yang didukung oleh Percona. Ini adalah gratis, sepenuhnya kompatibel, dan pengganti untuk edisi Komunitas MongoDB. Ini juga menyediakan fitur “tingkat perusahaan” yang seharusnya hanya tersedia di MongoDB Edisi Enterprise, misalnya:Otentikasi dan Otorisasi LDAP, Logging Audit, Otentikasi Kerberos.
Memutakhirkan Server Percona untuk MongoDB sangat mudah. Di blog ini, kita akan membahas beberapa tips upgrade dan menunjukkan contoh cara upgrade dari versi 3.6 ke versi 4.0.
Persiapan Upgrade
Sebelum menjalankan upgrade, Anda mungkin ingin melakukan beberapa persiapan. Selalu periksa perubahan kompatibilitas dalam dokumentasi dan di sisi aplikasi Anda; periksa dokumentasi yang terkait dengan perubahan dan peningkatan fitur, fungsionalitas usang (jika ada).
Periksa matriks kompatibilitas driver untuk MongoDB guna memahami apakah Anda juga perlu memutakhirkan driver.
Siapkan daftar periksa langkah demi langkah tentang bagaimana pemutakhiran akan dijalankan. Tuliskan rencana aksi, pihak-pihak perlu dilibatkan dalam dokumentasi, rencana rollback untuk skenario terburuk.
Memperbarui Server Percona untuk MongoDB
Selalu baik untuk menguji pemutakhiran Anda di lingkungan pengembangan atau pementasan sebelum Anda pindah ke lingkungan produksi. Anda dapat membangun arsitektur MongoDB yang sama persis dengan produksi, pengujian, dan pemulihan data dari cadangan terakhir. Setelah itu, Anda dapat menguji pemutakhiran dan memvalidasi rencana pemutakhiran Anda, tidak hanya itu Anda bisa mendapatkan perkiraan berapa lama pemutakhiran akan berlangsung dan juga memverifikasi apakah aplikasi tersebut kompatibel dengan versi database yang baru.
Proses upgrade tinggal install package baru dari repositori percona, begini cara upgrade berbasis CentOS dari versi 3.6 ke versi 4.0.
Langkah Pertama
Jika Anda belum menginstal Percona Repository, Anda dapat menginstal percona-release-latest.
[[email protected] ~]# yum install https://repo.percona.com/yum/percona-release-latest.noarch.rpm
Loaded plugins: fastestmirror
percona-release-latest.noarch.rpm | 19 kB 00:00:00

Setelah menginstal repositori Percona, aktifkan Server Percona untuk MongoDB 4.0
[[email protected] ~]# percona-release enable psmdb-40

Complete!Langkah Empat
Akhirnya, mulai layanan mongod.
$ systemctl start mongod.serviceProses instalasi berbasis Ubuntu/Debian serupa, Anda hanya memerlukan perintah dari APT package manager.
Dalam arsitektur MongoDB yang sangat tersedia, Anda dapat melakukan upgrade bergulir untuk meminimalkan waktu henti.
Jika aplikasi Anda sudah mendukung versi MongoDB terbaru, Anda dapat menyetel parameternya
setFeatureCompatibilityVersion after the upgrade was completed.
> db.adminCommand( { setFeatureCompatibilityVersion: "4.0" } )Verifikasi Tingkatkan Versi
Anda dapat memverifikasi apakah pemutakhiran berhasil dengan menghubungkan langsung ke instans MongoDB. Periksa apakah database berjalan dengan versi yang benar:
> db.version()Atau Anda dapat memeriksa dari baris perintah:
[[email protected] lib]# mongod --version
db version v4.0.20-14
