pada part2 ini kita akan membahas seputar SQL database dan memcached. untuk database yang akan kita gunakan adalah MariaDB. jalankan perintah dibawah ini pada Controller
[CONTROLLER NODE]
Install dan config mariadb server
|
1 |
root@controller:~# apt install mariadb-server python-pymysql |
setelah install packet diatas, maka buat dan edit file di /etc/mysql/mariadb.conf.d/99-openstack.cnf
- tambahkan [mysqld] kemudian set bind-address menjadi ip management controller
|
1 2 3 4 5 6 7 8 9 10 |
root@controller:~# nano /etc/mysql/mariadb.conf.d/99-openstack.cnf [mysqld] bind-address = 10.0.0.10 default-storage-engine = innodb innodb_file_per_table max_connections = 4096 collation-server = utf8_general_ci character-set-server = utf8 |
kemudian setelah itu restart database service
|
1 2 |
root@controller:~# /etc/init.d/mysql restart Restarting mysql (via systemctl): mysql.service. |
setelah direstart, kita akan mensetting database server dengan mysql_secure_installation, masukan passwordnya root
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 |
root@controller:~# mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): <masukan_password> OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation. You already have a root password set, so you can safely answer 'n'. Change the root password? [Y/n] n ... skipping. By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] Y ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] Y ... Success! By default, MariaDB comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n] Y - Dropping test database... ... Success! - Removing privileges on test database... ... Success! Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n] Y ... Success! Cleaning up... All done! If you've completed all of the above steps, your MariaDB installation should now be secure. Thanks for using MariaDB! |
Install dan config Message Queque
|
1 |
root@controller:~# apt install rabbitmq-server |
setelah itu, menambahkan user baru openstack di rabbitmq
|
1 2 |
root@controller:~# rabbitmqctl add_user openstack password_anda Creating user "openstack" ... |
memberikan akses berupa full access (read, write & execute) pada user openstack
|
1 2 |
root@controller:~# rabbitmqctl set_permissions openstack ".*" ".*" ".*" Setting permissions for user "openstack" in vhost "/" ... |
Install Memcached
memcached ini digunakan untuk mekanisme authentikasi pada identity service
|
1 |
root@controller:~# apt install memcached python-memcache |
kemudian edit file /etc/memcached.conf dan konfigurasi service untuk mengunakan ip management controller
|
1 2 3 4 |
root@controller:~# nano /etc/memcached.conf #-l 127.0.0.1 -l 10.0.0.10 |
cari pada bagian -l 127.0.0.1 dan rubah menjadi 0l 10.0.0.10 (ip management controller)
setelah itu restart service memcachednya
|
1 2 |
root@controller:~# /etc/init.d/memcached restart [ ok ] Restarting memcached (via systemctl): memcached.service. |
baik, untuk part2 cukup sampai disini, nanti kita akan lanjutkan pada part3 untuk pembahasan identity service (keystone)
wassalam…..
