🌲 preface

On August 13, 2021, Oracle 21C officially released the Linux64 local installation package.

In order to experience and improve my Oracle one-click setup script, I downloaded and installed a wave of it, and share the installation process below.

❤️ also releases the latest OracleShell scripts, supporting single-node deployment in 21C and one-click deployment in RAC.

How to obtain scripts:

🌛 Environment Preparations

Vagrant is still used for one-click deployment of OS environment, which is relatively convenient and quick.

❤ ️Play with the Vagrant series of columns❤ ️

I’m lazy, so I’m using Vagrant, but I’ll install the host environment manually and just run the script.

Environmental information:

Vagrant host image sources (7, 8) :

generic/oracle7 generic/oracle8

Oracle 21C installation package

Database Grid

☀️ 21C Single-node deployment

Vagrant deploys the hosting environment

📢 Note: If you manually install the operating system, you can skip this section and go directly to theOracle installationChapter.

Vagrant mirror source added

Here I downloaded my image source to /Users/ LPC /Downloads/ and renamed it oel7_pd and box oel7.

vagrant box add /Users/lpc/Downloads/oel7_pd --name oel7
vagrant box list
Copy the code

2. Configure VagrantFile

📢 Note: Please fill in the following information according to your own environment!!

Go to the custom directory and execute the following script to create the VagrantFile:

cat <<EOF>VagrantFile Vagrant.configure("2") do |config| config.vm.box = "oel7" config.vm.provision :shell, path: "/Volumes/DBA/vagrant/ora21c/scripts/ora_preinstall.sh" config.vm.synced_folder "/Volumes/DBA/vagrant/software", "/vagrant" config.vm.network :forwarded_port, guest: 1521, host: 1521 config.vm.network :forwarded_port, guest: 22, host: 22 config.vm.network "public_network", ip: "10.211.55.100" config. The vm. The provider "parallels do | to | pd, pd name =" ora21c "pd. The memory = 8192 pd. Cpus = 2 end end EOF
Copy the code

⚠️ Note: How to configure VagrantFile is not explained here, but refer to the column. I’m going to use thetaParallelsVirtual machine software, if using Virtualbox virtual machine software friends, will need to scriptparallelsModified tovirtualboxCan.

3. Prepare installation media and scripts

Basically configure these two lines in the VagrantFile:

config.vm.provision :shell, path: "/Volumes/DBA/vagrant/ora21c/scripts/ora_preinstall.sh"
config.vm.synced_folder "/Volumes/DBA/vagrant/software", "/vagrant"
Copy the code

The first line refers to the script that automatically configates the operating system once the Vagrant host is installed. The second line indicates that the Vagrant host automatically maps directories once it is installed.

Ora_preinstall. sh Script contents:

cat <<EOF>ora_preinstall.sh
#change root password
echo oracle | passwd --stdin root
#change sshd_config
sed -i 's/PasswordAuthentication no/PasswordAuthentication yes/' /etc/ssh/sshd_config
systemctl reload sshd.service
#mkdir software dir
mkdir /soft
#cp software to softdir
cp /vagrant/* /soft
#chmod shell script
chmod +x /soft/OracleShellInstall.sh
EOF
Copy the code

Installation media content:

LINUX.X64_213000_db_home.zip
OracleShellInstall.sh
Copy the code

You only need to upload the Oracle one-click installation script and the Oracle 21C Database installation package.

4. Initialize the host environment

If you are using the Virtualbox virtual machine software, perform Vagrant Up. Those who use the Parallels virtual machine software need to perform Vagrant up –provider= Parallels.

vagrant up --provider=parallels
Copy the code

After a short wait, the host is successfully initialized:

Oracle 21C standalone script installation

Once the environment is ready, performing the installation is as simple as a single command line.

Use XSHELL or other tools to connect to the host and execute the script:

/ oracleshellinstall. sh -i 10.211.55.100 -iso NCopy the code

To explain, Vagrant’s initial environment is configured with yum sources, so there is no need to manually mount the image sources, so I added the parameter -iso N. Those who manually install the OS still need to manually mount the image sources.

The installation process takes less than 30 minutes. To create a PDB, add the -pb PDB name.

More customized parameters can be seen before: Year ️ I wrote over 4000 lines of Shell scripts and finally implemented one-click Oracle RAC installation!! .
