Apache Cassandra adalah database NoSQL open source dan bebas yang memberikan skalabilitas linier dan ketersediaan tinggi tanpa mengorbankan kinerja. Apache Cassandra digunakan oleh sejumlah organisasi termasuk Apple, NetFlix, eBay, dan Easou.<\/p>\n

Dalam tutorial ini, kami akan menunjukkan kepada Anda bagaimana menginstal Apache Cassandra di CentOS 7.<\/p>\n

Prasyarat<\/h2>\n

Agar dapat menginstal paket pada sistem CentOS, Anda harus masuk sebagai pengguna dengan hak istimewa sudo<\/a>.<\/p>\n

Install Apache Cassandra di CentOS 7<\/h2>\n

Cara termudah untuk menginstal Apache Cassandra di CentOS 7 adalah dengan menginstal paket deb dari repositori Apache Cassandra resmi.<\/p>\n

Pada saat penulisan artikel ini, versi terbaru dari Apache Cassandra adalah 3.11<\/code> dan membutuhkan OpenJDK 8 untuk diinstal pada sistem.<\/p>\n

Instalasi Java di CentOS 7<\/a>\u00a0cukup sederhana, mulai dengan memperbarui indeks paket dan Instal paket OpenJDK dengan mengetik::<\/p>\n

sudo yum install java-1.8.0-openjdk-devel<\/pre>\n
Verifikasi instalasi Java dengan menjalankan perintah berikut yang akan mencetak versi Java:<\/p>\n
java -version<\/pre>\n
Outputnya akan terlihat seperti ini:<\/p>\n
openjdk version \"1.8.0_201\"
\nOpenJDK Runtime Environment (build 1.8.0_201-b09)
\nOpenJDK 64-Bit Server VM (build 25.201-b09, mixed mode)<\/pre>\n
Buka editor pilihan Anda dan buat file repositori berikut:<\/p>\n
sudo nano \/etc\/yum.repos.d\/webmin.repo<\/pre>\n
[cassandra]
\nname=Apache Cassandra
\nbaseurl=https:\/\/www.apache.org\/dist\/cassandra\/redhat\/311x\/
\ngpgcheck=1
\nrepo_gpgcheck=1
\ngpgkey=https:\/\/www.apache.org\/dist\/cassandra\/KEYS<\/pre>\n
Setelah repositori diaktifkan, instal versi terbaru dari Apache Cassandra dengan mengetik:<\/p>\n
sudo yum install cassandra<\/pre>\n
Start dan Aktfikan layanan dengan perintah berikut :<\/p>\n
sudo systemctl enable cassandra
\nsudo systemctl start cassandra<\/pre>\n
Anda dapat memverifikasi bahwa Cassandra sedang berjalan dengan mengetik:<\/p>\n
nodetool status<\/pre>\n
Anda akan melihat output yang mirip dengan ini:<\/p>\n
Datacenter: datacenter1
\n=======================
\nStatus=Up\/Down
\n|\/ State=Normal\/Leaving\/Joining\/Moving
\n--  Address    Load        Tokens       Owns (effective)  Host ID         Rack
\nUN  127.0.0.1  114.55 KiB  256          100.0% d8c27r23-ea22-4eec-813c-5967218ba793  rack1<\/pre>\n
Pada poin ini, Anda telah menginstal Apache Cassandra di sistem CentOS Anda.<\/p>\n
Mengkonfigurasi Apache Cassandra di CentOS 7<\/h2>\n
Data Apache Cassandra disimpan di direktori \/var\/lib\/cassandra<\/code>, file konfigurasi terletak di \/etc\/cassandra<\/code> dan opsi start-up Java dapat dikonfigurasikan di file \/etc\/default\/cassandra<\/code>.<\/p>\n
Secara default, Cassandra dikonfigurasikan untuk listen di localhost saja. Jika klien yang terhubung ke database juga berjalan di host yang sama Anda tidak perlu mengubah file konfigurasi default.<\/p>\n
Untuk berinteraksi dengan Cassandra melalui CQL (Cassandra Query Language<\/em>) Anda dapat menggunakan utilitas baris perintah bernama cqlsh<\/code> yang datang bersama paket Cassandra.<\/p>\n
cqlsh<\/pre>\n
Connected to Test Cluster at 127.0.0.1:9042.
\n[cqlsh 5.0.1 | Cassandra 3.11.4 | CQL spec 3.4.4 | Native protocol v4]
\nUse HELP for help.
\ncqlsh><\/pre>\n
Mengganti nama\u00a0Cluster Apache Cassandra<\/h2>\n
Secara default, cluster Cassandra bernama \u201cTest Cluster\u201d. Jika Anda ingin mengubahnya ikuti langkah-langkah di bawah ini:<\/p>\n
    \n
  1. Masuk ke terminal Cassandra CQL dengan cqlsh<\/code>:\n
    cqlsh<\/pre>\n
    Jalankan perintah berikut untuk mengubah nama cluster, semisal menjadi \u201cCluster Linuxid\u201d:<\/p>\n
    UPDATE system.local SET cluster_name=\"Cluster Linuxid\" WHERE KEY = 'local';<\/pre>\n
    Ubah \u201cCluster Linuxid<\/strong>\u201d dengan nama yang Anda inginkan. Setelah selesai ketik exit<\/code> untuk keluar dari konsol.<\/p>\n<\/li>\n
  2. Edit file konfigurasi cassandra.yaml<\/code> dan masukkan nama cluster baru Anda.\n
    cluster_name: 'Cluster Linuxid'<\/pre>\n<\/li>\n
  3. Jalankan perintah berikut untuk menghapus cache sistem:\n
    nodetool flush system<\/pre>\n<\/li>\n
  4. Terakhir,\u00a0restart layanan Cassandra:\n
    sudo systemctl restart cassandra<\/pre>\n<\/li>\n<\/ol>\n
    Kesimpulan<\/h2>\n
    Anda telah berhasil menginstal Apache Cassandra di CentOS 7. Anda sekarang dapat mengunjungi halaman Dokumentasi\u00a0resmi \u00a0Apache Cassandra<\/a>\u00a0dan belajar bagaimana memulai dengan Cassandra.<\/p>\n","protected":false},"excerpt":{"rendered":"
