apt install dnsmasq

Tambahkan baris berikut pada file /etc/dnsmasq.conf


Stop service systemd-resolved

systemctl disable --now systemd-resolved
systemctl stop systemd-resolved

Restart dnsmasq

systemctl enable --now dnsmasq
systemctl restart dnsmasq

Konfigurasi /etc/resolv.conf

vi /etc/resolv.conf

Isi dengan baris berikut

search imanudin.web.id

Testing DNS

host -t MX imanudin.web.id

Hasilnya lebih kurang akan seperti ini

Catatan: ganti DB_ADM_PWD dengan password yang lebih kuat

## Berikan akses node lain terhadap Postgresql

Jalankan perintah berikut

su - postgres -c "psql --command=\"ALTER SYSTEM SET listen_addresses TO '*';\""
su - postgres -c "psql --command=\"ALTER SYSTEM SET max_connections = 500;\""
su - postgres -c "psql --command=\"ALTER SYSTEM SET shared_buffers = 5000;\""
su - postgres -c "psql --command=\"ALTER SYSTEM SET port TO '5433';\""
echo "host    all             all               md5" >> /etc/postgresql/12/main/pg_hba.conf

Restart service postgresql

systemctl restart postgresql

## Setup PGPool

apt install pgpool2

Jalanakan perintah berikut untuk membuat pgpool.conf

echo "backend_clustering_mode = 'raw'
port = 5432
backend_hostname0 = 'localhost'
backend_port0 = 5433
backend_flag0 = 'DISALLOW_TO_FAILOVER'
num_init_children = 32
reserved_connections=1" > /etc/pgpool2/pgpool.conf

Restart service pgpool

systemctl enable --now pgpool2
systemctl restart pgpool2.service

ens160, fe80::20c:29ff:fee9:cd29/64
Specify the binding address for service discovery:
Create the cluster credentials password (will be used for setups): 
Type the credential password again: 

Untuk melengkapi setup carbonio mesh, jalankan perintah berikut

pending-setups -a

Masukkan password mesh secret yang sudah disetup sebelumnya. Password mesh secret disimpan pada file /var/lib/service-discover/password. Jika lupa password mesh secret, silakan lihat isi dari file tersebut

Berikut sample outputnya

root@ubuntu:/srv# pending-setups -a
Insert the cluster credential password:

Jalankan kembali perintah di atas untuk memastikan tidak ada service mesh yang masih pending

## Bootstrap Initial Carbonio Database

Jalankan perintah berikut untuk membuat initial database fitur files, tasks, chat, dan video

PGPASSWORD=DB_ADM_PWD carbonio-files-db-bootstrap carbonio_adm
PGPASSWORD=DB_ADM_PWD carbonio-tasks-db-bootstrap carbonio_adm
PGPASSWORD=DB_ADM_PWD carbonio-ws-collaboration-db-bootstrap carbonio_adm
PGPASSWORD=DB_ADM_PWD carbonio-message-dispatcher-db-bootstrap carbonio_adm

Berikut adalah contoh outputnya

root@ldap1:~# PGPASSWORD=DB_ADM_PWD carbonio-files-db-bootstrap carbonio_adm
Database: user carbonio_adm
Check postgres connection: OK
carbonio-files-db database initialized successfully!

## Restart service Zextras

su - zextras
zmcontrol stop
zmcontrol start

Pastikan servicenya dalam keadaan running setelah direstart

zextras@ldap1:~$ zmcontrol status
Host ldap1.imanudin.web.id
	directory-server        Running
	service-discover        Running
	stats                   Running
	config service          Running

## Dapatkan password LDAP service

Jalankan perintah berikut untuk mendapatkan password dari LDAP service

zmlocalconfig -s | grep -i ldap | grep -i password
zextras@ldap1:~$ zmlocalconfig -s | grep -i ldap | grep -i password
ldap_amavis_password = SmotPq14w
ldap_nginx_password = SmotPq14w
ldap_postfix_password = SmotPq14w
ldap_replication_password = SmotPq14w
ldap_root_password = SmotPq14w
zimbra_ldap_password = SmotPq14w

Catat password LDAP service di atas. Password tersebut akan digunakan pada saat instalasi node lain seperti mailbox server dan mta+proxy server.
