This article will explain in detail how to manually compile and configure ceph. The content of the article is of high quality, so the editor will share it for you as a reference. I hope you will have some understanding of the relevant knowledge after reading this article.

First, compile the ceph source code manually.

1. Download the ceph source code.

Download the latest version of ceph source code from the Aliyun open source image website at the following address: http://mirrors.aliyun.com/ceph/tarballs/ceph_10.2.1.orig.tar.gz

2. Compile the ceph source code.

1) compile the description of the running environment.

The compilation and running environment used is ubuntu16.04-server-amd64. Update the running environment to the latest after installing the ubuntu image.

# apt-get update

# apt-get upgrade

2) decompress the source code.

# mkdir-p / root/src

# tar-xf ceph_10.2.1.orig.tar.gz-C/root/src

3) install the compilation dependency package.

A) execute the install_deps.sh script in the ceph source directory to install the necessary dependencies (this script does not fully install and compile all the dependencies of the ceph source code)

# cd ceph-10.2.1

#. / install-deps.sh

B) install additional dependency packages.

# apt-get install libtool automake pkg-config cython libsnappy-dev libleveldb-dev libblkid-dev libudev-dev libkeyutils-dev libcryto++-dev libfuse-dev libatomic-ops-dev libaio-dev xfslibs-dev libboost-dev libboost-iostreams-dev libboost-random-dev libboost-program-options-dev libldap2-dev virtualenv python-pip zlib1g-dev libcurl4-nss-dev libfcgi-dev libssl-dev

4) configure the ceph source code.

# cd ceph-10.2.1

#. / autogen.sh

# / configure-- prefix=/usr-- libexecdir=/usr/lib-- sysconfdir=/etc-- with-radosgw-- with-rados-- with-rbd-- with-cephfs-- with-debug-- with-nss-- without-libcryptopp

5) compile the ceph source code.

# make-j32

3. Install ceph source code.

After compiling successfully, execute make install to install ceph and run it locally.

# make install

Second, configure the ceph running environment.

1. Hardware description of ceph running environment.

The hardware running environment used by ceph is Huawei server, where CPU is Xeon E5-2650 v2, memory 128GB, there are 4 SAS disks of 600GB, one of which is used as system disk, and the other three are used as ceph storage nodes.

2. Configure the monitor node.

1) check whether the / etc/ceph directory exists, and create one manually if it does not exist. Generally speaking, the / etc/ceph directory is automatically generated after make install is executed

2) create / etc/ceph/ceph.conf configuration file

# vim / etc/ceph/ceph.conf

3) create a unique ID

# uuidgen

4) write the created unique ID value to the ceph.conf configuration file

Fsid = xxxx-yyyy-zzzz

5) fill in the monitor node member name and ip address in ceph.conf

Mon initial members = BMMI 79-5

Mon host = 192.168.250.93

6) create a monitor keyring

# ceph-authtool-create-keyring / tmp/ceph.mon.keyring-gen-key-n mon. -cap mon 'allow *'

7) create a client.admin keyring

# ceph-authtool-create-keyring / etc/ceph/ceph.client.admin.keyring-gen-key-n client.admin-set-uid=0-cap mon 'allow *' osd 'allow *' mds' allow'

8) add key of client.admin to keyring of monitor

# ceph-authtool / tmp/ceph.mon.keyring-import-keying / etc/ceph/ceph.client.admin.keyring

9) initialize monmap

# monmaptool-create-add BMI 79-5 192.168.250.93-fsid xxxx-yyyy-zzzz / tmp/monmap

10) create a monitor working directory

# mkdir-p / var/lib/ceph/mon/ceph-B-79-5

11) initialize the monitor process with monmap and monitor keyring

# su-ceph ceph-mon-mkfs-I Bmuri 79-5-monmap / tmp/monmap-keyring / tmp/ceph.mon.keyring

12) set the owner of monitor working directory to ceph user

# chown-R ceph:ceph / var/lib/ceph/mon/ceph-B-79-5

13) identifies that the monitor node is initialized and can be started

# touch / var/lib/ceph/mon/ceph-B-79-5/done

14) create a directory used by ceph asok

# mkdir-p / var/run/ceph

# chown-R ceph:ceph / var/run/ceph

14) start the monitor process

# systemctl start ceph-mon@B-79-5

15) View the status of the current ceph

# ceph-s

3. Configure the osd node.

1) generate unique ID for OSD node

# uuidgen # this command returns the unqiue ID string aaaa-bbbb-cccc

2) create an OSD node

# ceph osd create aaaa-bbbb-cccc # this command returns the OSD node number {id} created

3) create a working directory for OSD nodes

# mkdir-p / var/lib/ceph/osd/ceph- {id}

4) create an OSD disk and mount it to the working directory of the OSD node

# mkfs.xfs / dev/sdb1

# mount / dev/sdb1 / var/lib/ceph/osd/ceph- {id}

5) initialize the working directory of the OSD node

# ceph-osd-I {id}-mkfs-mkkey-osd-uuid aaaa-bbbb-cccc

6) sign up for OSD node authentication key

# ceph auth add osd. {id} osd' allow * 'mon' allow profile osd'-I / var/lib/ceph/osd/ceph- {id} / keyring

7) add OSD node to CrushMap

# ceph osd crush add-bucket virtual-node {id} host

# ceph osd crush move virtual-node {id} root=default

# ceph osd crush add osd. {id} 1.0 host=virtual-node {id}

8) set the working directory owner of the OSD node to ceph

# chown-R ceph:ceph / var/lib/ceph/osd/ceph- {id}

9) start the OSD process

# systemctl start ceph-osd@ {id}

10) View ceph status

# ceph-s

Add the remaining two OSDs nodes in the same way.

Third, matters needing attention.

1. Note the access permissions of / tmp/ceph.mon.keyring and / tmp/monmap, which is best set to 0644.

2. Pay attention to the owner and access rights of the working directory of monitor and OSD nodes, that is, the owner is ceph, and the access right should be set to 0644.

3. The basic ceph.conf file is as follows:

/ etc/ceph/ceph.conf

[global]

Fsid = a7f64266-0894-4f1e-a635-d0aeaca0e993

Mon initial members = BMMI 79-5

Mon host = 192.168.250.93

Public network = 192.168.250.0 Universe 24

Auth cluster required = cephx

Auth service required = cephx

Auth client required = cephx
