Unzip the file with the command: #tar -xzvf v11.1_linux圆4_server_t.tar.gz Start the installationĪfter unzipping the file a server_t folder is created, enter to this directory.Įxecute the following command to know if the server complies with the installation requirements. Open the terminal with the command line and connect with the root user: $su -Įnter to the folder where the file is (in my case): #cd /home/juanleon/Downloads We can save the file in the Downloads folder of the user that we are connected to.

If SELinux is in the disabled state, it is ok. For the installation of the database engine I am using a VM upon Oracle Virtual Box with a minimum configuration of: 2 vCPUs, 4 GBytes de RAM, 40 GBytes HD and "bridge adapter" for the network interface.įrom the terminal on the command line, connect with the root user: $su -Ĭheck if SELinux is active, with the command: #sestatus To install CentOS 7 you can execute the following procedure. Since it is necessary to dimension the workload that the database will perform through a capacity planning to have a correct configuration. It should not be used for groups of developers, do not consider for production environments.
