CEPH Node Settings

Notice that the machines I configured are hostname, which are osd0, osd1, mds, and ceph-admin. Ceph-admin is used to install mon and ceph-deploy)

Perform the following steps:

1. Create a user on each Ceph node.

Ssh user@ceph-server

Sudo useradd-d / home/ceph-m ceph

Sudo passwd ceph

two。 Add root permissions to users in each Ceph node

Echo "ceph ALL = (root) NOPASSWD:ALL" | sudo tee / etc/sudoers.d/ceph

Sudo chmod 0440 / etc/sudoers.d/ceph

3. Install a SSH server, if necessary:

Sudo apt-get install openssh-server

Sudo yum install openssh-server

4. Configure your ceph-deploy management node by connecting to each Ceph node with a password-less SSH. Leave the password blank:

Ssh-keygen

Generating public/private key pair.

Enter file in which to save the key (/ ceph-client/.ssh/id_rsa):

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in / ceph-client/.ssh/id_rsa.

Your public key has been saved in / ceph-client/.ssh/id_rsa.pub.

5. Copy the key to each Ceph node.

Ssh-copy-id ceph@ceph-server

6. Modify the ~ / .ssh/config file of your ceph-deploy management node so that it can be logged to the Ceph node like the users you created (e.g., ceph).

Host ceph-server

Hostname ceph-server.fqdn-or-ip-address.com

User ceph

7. Use and hostname ping to determine connectivity (for example, not an IP address). It is necessary to solve the host name resolution problem and firewall problem.

CEPH deployment Settings

Add Ceph database to ceph-deploy management node. After that, install ceph-deploy.

Important: if you are logged in with a different user, do not run ceph-deploy with sudo or root privileges, because you cannot issue sudo commands on remote hosts

Advanced package Management tool (APT)

For Debian and Ubuntu releases, perform the following steps:

1. Add a release key

Wget-Q-O-'https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc' | sudo apt-key add-

two。 Add Ceph packages to your repository and replace {ceph-stable-release} (such as cuttlefish, dumpling, etc.) with a stable Ceph distribution, such as

Echo deb http://ceph.com/debian-{ceph-stable-release}/ $(lsb_release-sc) main | sudo tee / etc/apt/sources.list.d/ceph.list

Notice that there are spaces here. The end result is

Http://ceph.com/debian-giant/ trusty main

3. Update your warehouse and install ceph-deploy

Sudo apt-get update & & sudo apt-get install ceph-deployRed Hat package Manager (RPM)

For platforms such as Red Hat (rhel6), CentOS (el6), Fedora 17-19 (f17-f19), OpenSUSE 12 (opensuse12), and SLES (sles11), follow these steps:

1. Add packages to your warehouse. Open a text editor and create a Yellowdog update, modify (YUM) entry, using the path / etc/yum.repos.d/ceph.repo, for example:

Sudo vim / etc/yum.repos.d/ceph.repo

Paste the following sample code. Replace {ceph-stable-release} (such as dumpling, etc.) with a stable Ceph distribution. R replace {distro} (such as el6 for CentOS 6, rhel6 for Red Hat 6, fc18 or fc19 for Fedora 18 or Fedora 19 and sles11 for SLES 11) with your Linux distribution. Finally, save the file to / etc/yum.repos.d/ceph.repo.

[ceph-noarch]

Name=Ceph noarch packages

Baseurl= http://ceph.com/rpm-{ceph-stable-release}/{distro}/noarch

Enabled=1

Gpgcheck=1

Type=rpm-md

Gpgkey= https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc

two。 Update your warehouse and install ceph-deploy
