# Installing Odoo on Linux VPS/Cloud

**Installing an Odoo server requires** root access **to the server provided with our private plans (VPS/Cloud).**

Below are some generalized recommendations based on the number of websites you wish to host with the application:

* For a 5 user site = 2 CPU server and 2 GB Ram

* For 20 user site = 4 CPU server and 8 GB Ram

* For 100+ user site = 2 x 8 CPU servers with 32 GB Ram

1. Log in to your server as **user root**.

`ssh root@IP`

2. At the very beginning it is best to start a screen session by executing the following command:

`screen -U -S odoo`

and make sure that all services installed on your server are up to date:

`yum -y update`

3. Odoo **uses a PostgreSQL database**, so we have to remove MariaDBserver if it is installed:

`yum remove mariadb mariadb-server`

4. In order to install all Odoo 9 dependencies the **EPEL repository** must be added to the distribution’s repositories:

`yum install -y epel-release`

5. Install PostgreSQL server:

`yum install -y postgresql-server`

Once it is installed and started for the first time, we have to initialize the PostgreSQL database:

`postgresql-setup initdb`

Start the PostgreSQL server and enable it to start at boot time

`systemctl start postgresqlsystemctl enable postgresql`

PS: If you have Cpanel installed, the PostgreSQL needs to be installed using the script below:

`/usr/local/cpanel/scripts/installpostgres`

6. Create new yum repository for Odoo:

`nano /etc/yum.repos.d/odoo.repo`

With the following content:

`[odoo-nightly]name=Odoo Nightly repositorybaseurl=http://nightly.odoo.com/9.0/nightly/rpm/enabled=1gpgcheck=1gpgkey=https://nightly.odoo.com/odoo.key`

and finally install Odoo 9:

`yum install -y odoo`

7. This will install the latest version of Odoo and all its dependencies.

After the installation is completed, start Odoo and enable it to start at boot times:

`systemctl start odoosystemctl enable odoo`

8. Open **Odoo’s configuration file** and **uncomment the ‘admin\\\_passwd’** line to set the admin master password:

`vim /etc/odoo/openerp-server.confadmin\_passwd = YourPassword`

Don’t forget to replace ‘YourPassword’ with an actual strong password.

9. **Restart Odoo** for the changes to take effect:

`systemctl restart odoo`
