See <a href="https://docs.oracle.com/en/operating-systems/olcne/1.7/start/hosts.html#hosts">Getting Started with OLCNE</a>.</p> <p>The cluster must have at least 3 worker nodes.</p> </li> <li> <p>Create an NFS server. For an example that uses an NFS server on Oracle Linux, see <a href="https://docs.oracle.com/en/learn/create_nfs_linux/">Create an NFS server on Oracle Linux</a>.</p> <p>a. Install the NFS utility package on the server and client instances. <style type="text/css"> code { margin: 0; padding: 0; } .copy-code-button { position: absolute; right: 0; top: -29px; font-size: 12px; line-height: 14px; width: 65px; color: white; background-color: #30638E; border: 1px solid #30638E; white-space: nowrap; padding: 6px 6px 7px 6px; } .copy-code-button:hover, .copy-code-button:focus{ background-color: gray; opacity: 1; } </style> <div class="clipboard"> <div class="highlight"> <pre tabindex="0"><code>$ sudo dnf install -y nfs-utils </code></pre></div> </div> <script> function createCopyButton(highlightDiv) { const button = document.createElement("button"); button.innerText = "Copy"; button.className = "copy-code-button"; button.addEventListener("click", () => copyCodeToClipboard(button, highlightDiv) ); addCopyButton(button, highlightDiv); } function addCopyButton(button, highlightDiv) { highlightDiv.insertBefore(button, highlightDiv.firstChild); const wrapper = document.createElement("div"); highlightDiv.parentNode.insertBefore(wrapper, highlightDiv); wrapper.appendChild(highlightDiv); } async function copyCodeToClipboard(button, highlightDiv) { let codeToCopy = highlightDiv.querySelector(":last-child > code, pre").innerText; let codeBlock = codeToCopy.split("\n"); let expectedLine = codeBlock.findIndex(line => line.toLowerCase().startsWith("# expected response") || line.toLowerCase().startsWith("# sample output")); if (expectedLine !== -1) { codeBlock.splice(expectedLine); } codeToCopy = codeBlock.join("\n"); codeToCopy = codeToCopy.replace(/^#(.*)$/gm, '').trim(); codeToCopy = codeToCopy.replace(/\$\s+/gm, '').trim(); codeToCopy = codeToCopy.replace(/\n{2,}/g,'\n'); console.log(codeToCopy); try { await navigator.clipboard.writeText(codeToCopy); } catch (err) { const textarea = document.createElement('textarea'); textarea.value = codeToCopy; document.body.appendChild(textarea); textarea.select(); document.execCommand('copy'); textarea.remove(); } button.blur(); button.innerText = "Copied"; setTimeout(function () { button.innerText = "Copy"; }, 2000); } document .querySelectorAll(".highlight") .forEach((highlightDiv) => createCopyButton(highlightDiv)); </script></p> <p>b.
