[Ceph001]基于CentOS7部署Ceph集群（版本10.2.2）

 

1 简单介绍

Ceph的部署模式下主要包含以下几个类型的节点

Ø Ceph OSDs: A Ceph OSD 进程主要用来存储数据，处理数据的replication,恢复，填充，调整资源组合以及通过检查其他OSD进程的心跳信息提供一些监控信息给Ceph Monitors . 当Ceph Storage Cluster 要准备2份数据备份时，要求至少有2个Ceph OSD进程的状态是active+clean状态 (Ceph 默认会提供两份数据备份).

Ø Monitors: Ceph Monitor 维护了集群map的状态，主要包括monitor map, OSD map, Placement Group (PG) map, 以及CRUSH map. Ceph 维护了 Ceph Monitors, Ceph OSD Daemons, 以及PGs状态变化的历史记录 (called an “epoch”).

Ø MDSs: Ceph Metadata Server (MDS)存储的元数据代表Ceph的文件系统 (i.e., Ceph Block Devices 以及Ceph Object Storage 不适用 MDS). Ceph Metadata Servers 让系统用户可以执行一些POSIX文件系统的基本命令，例如ls,find 等.

2 集群规划

在创建集群前，首先做好集群规划。

2.1 网络拓扑

基于VMware虚拟机部署ceph集群：

2.2 节点规划

Hostname(如何更新)

VmNet

节点IP

说明

node0

HostOnly

192.168.92.100

Admin, osd(sdb)

 

node1

HostOnly

192.168.92.101

Osd(sdb),mon

 

node2

HostOnly

192.168.92.102

Osd(sdb),mon,mds

 

node3

HostOnly

192.168.92.103

Osd(sdb),mon,mds

 

client-node

HostOnly

192.168.92.109

用户端节点；客服端，主要利用它挂载ceph集群提供的存储进行测试

 

3 准备工作

3.1 root权限准备

分别为上述各节点主机创建用户ceph:(使用root权限，或者具有root权限)

创建用户

[root@node0 ~]# adduser -d /home/ceph -m ceph

设置密码

[root@node0 ~]#passwd ceph

设置账户权限

[root@node0 ~]# echo “ceph ALL = （root) NOPASSWD:ALL” | sudo tee /etc/sudoers.d/ceph[root@node0 ~]# chomod 0440 /etc/sudoers.d/ceph

3.2 管理节点修改hosts

修改/etc/hosts

[ceph@node0 cluster]$ sudo cat /etc/hosts[sudo] password for ceph:127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4::1 localhost localhost.localdomain localhost6 localhost6.localdomain6192.168.92.100 node0192.168.92.101 node1192.168.92.102 node2192.168.92.103 node3[ceph@node0 cluster]$

3.3 requiretty准备

执行命令visudo修改suoders文件：

1. 注释Defaults requiretty

Defaults requiretty修改为 #Defaults requiretty， 表示不需要控制终端。

否则会出现sudo: sorry, you must have a tty to run sudo

2. 增加行 Defaults visiblepw

否则会出现 sudo: no tty present and no askpass program specified

如果在ceph-deploy new <node-hostname>阶段依旧出错：

[ceph@node0 cluster]$ ceph-deploy new node1 node2 node3[ceph_deploy.conf][DEBUG ] found configuration file at: /home/ceph/.cephdeploy.conf[ceph_deploy.cli][INFO ] Invoked (1.5.28): /usr/bin/ceph-deploy new node3[ceph_deploy.cli][INFO ] ceph-deploy options:[ceph_deploy.cli][INFO ] username : None[ceph_deploy.cli][INFO ] func : <function new at 0xee0b18>[ceph_deploy.cli][INFO ] verbose : False[ceph_deploy.cli][INFO ] overwrite_conf : False[ceph_deploy.cli][INFO ] quiet : False[ceph_deploy.cli][INFO ] cd_conf : <ceph_deploy.conf.cephdeploy.Conf instance at 0xef9a28>[ceph_deploy.cli][INFO ] cluster : ceph[ceph_deploy.cli][INFO ] ssh_copykey : True[ceph_deploy.cli][INFO ] mon : ['node3'][ceph_deploy.cli][INFO ] public_network : None[ceph_deploy.cli][INFO ] ceph_conf : None[ceph_deploy.cli][INFO ] cluster_network : None[ceph_deploy.cli][INFO ] default_release : False[ceph_deploy.cli][INFO ] fsid : None[ceph_deploy.new][DEBUG ] Creating new cluster named ceph[ceph_deploy.new][INFO ] making sure passwordless SSH succeeds[node3][DEBUG ] connected to host: node0[node3][INFO ] Running command: ssh -CT -o BatchMode=yes node3[node3][DEBUG ] connection detected need for sudo[node3][DEBUG ] connected to host: node3[ceph_deploy][ERROR ] RuntimeError: remote connection got closed, ensure ``requiretty`` is disabled for node3[ceph@node0 cluster]$

3.4 管理节点的无密码远程访问权限

配置管理节点与其他节点ssh无密码root权限访问其它节点。

第一步：在管理节点主机上执行命令：

ssh-keygen

说明：（为了简单点命令执行时直接确定即可）

第二步：将第一步的key复制至其他节点

ssh-copy-id    ceph@node0

ssh-copy-id    ceph@node1

ssh-copy-id    ceph@node2

ssh-copy-id    ceph@node3

同时修改~/.ssh/config文件增加一下内容：

[ceph@node0 cluster]$ cat ~/.ssh/configHost node0Hostname node0User cephHost node1Hostname node1User cephHost node2Hostname node2User cephHost node3Hostname node3User ceph[ceph@node0 cluster]$

3.5 关闭防火墙

[root@localhost ceph]# systemctl stop firewalld.service[root@localhost ceph]# systemctl disable firewalld.serviceRemoved symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.[root@localhost ceph]#

3.6 禁用selinux

当前禁用

setenforce 0

永久禁用

[root@localhost ceph]# cat /etc/selinux/config# This file controls the state of SELinux on the system.# SELINUX= can take one of these three values:# enforcing - SELinux security policy is enforced.# permissive - SELinux prints warnings instead of enforcing.# disabled - No SELinux policy is loaded.SELINUX=disabled# SELINUXTYPE= can take one of three two values:# targeted - Targeted processes are protected,# minimum - Modification of targeted policy. Only selected processes are protected.# mls - Multi Level Security protection.SELINUXTYPE=targeted

3.6.1 Bad owner or permissions on .ssh/config的解决

错误信息：

Bad owner or permissions on /home/ceph/.ssh/config fatal: The remote end hung up unexpectedly

解决方案：

$sudo chmod 600 config

4 管理节点安装ceph-deploy工具

第一步：增加 yum配置文件

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

添加以下内容：

[Ceph-noarch]name=Ceph noarch packagesbaseurl=http://download.ceph.com/rpm-jewel/el7/noarchenabled=1gpgcheck=1type=rpm-mdgpgkey=https://download.ceph.com/keys/release.ascpriority=1

第二步：更新软件源并按照ceph-deploy，时间同步软件

[ceph@node0 cluster]$ sudo yum update && sudo yum install ceph-deploy[ceph@node0 cluster]$ sudo yum install ntp ntpupdate ntp-doc

第三步：关闭所有节点的防火墙以及安全选项(在所有节点上执行）以及其他一些步骤

[ceph@node0 cluster]$ sudo systemctl stop firewall.service;[ceph@node0 cluster]$ sudo systemctl disable firewall.service[ceph@node0 cluster]$ sudo yum install yum-plugin-priorities

总结：经过以上步骤前提条件都准备好了接下来真正部署ceph了。

5 创建Ceph集群

以前面创建的ceph用户在管理节点节点上创建目录()

[ceph@node0 ~]$ mkdir cluster[ceph@node0 cluster]$ cd cluster

5.1 如何清空ceph数据

先清空之前所有的ceph数据，如果是新装不用执行此步骤，如果是重新部署的话也执行下面的命令：

ceph-deploy purgedata {ceph-node} [{ceph-node}]

ceph-deploy forgetkeys

如：

[ceph@node0 cluster]$ <strong>ceph-deploy purgedata admin_node node1 node2 node3</strong>[ceph_deploy.conf][DEBUG ] found configuration file at: /home/ceph/.cephdeploy.conf[ceph_deploy.cli][INFO ] Invoked (1.5.28): /usr/bin/ceph-deploy purgedata node0 node1 node2 node3…[node3][INFO ] Running command: sudo rm -rf --one-file-system -- /var/lib/ceph[node3][INFO ] Running command: sudo rm -rf --one-file-system -- /etc/ceph/[ceph@node0 cluster]$ <strong>ceph-deploy forgetkeys</strong>[ceph_deploy.conf][DEBUG ] found configuration file at: /home/ceph/.cephdeploy.conf[ceph_deploy.cli][INFO ] Invoked (1.5.28): /usr/bin/ceph-deploy forgetkeys…[ceph_deploy.cli][INFO ] default_release : False[ceph@node0 my-cluster]$

5.2 创建集群设置Monitor节点

在admin节点上用ceph-deploy创建集群，new后面跟的是monitor节点的hostname，如果有多个monitor，则它们的hostname以为间隔，多个mon节点可以实现互备。

[ceph@node0 cluster]$ <strong>ceph-deploy new node1 node2 node3</strong>[ceph_deploy.conf][DEBUG ] found configuration file at: /home/ceph/.cephdeploy.conf[ceph_deploy.cli][INFO ] Invoked (1.5.34): /usr/bin/ceph-deploy new node1 node2 node3[ceph_deploy.cli][INFO ] ceph-deploy options:[ceph_deploy.cli][INFO ] username : None[ceph_deploy.cli][INFO ] func : <function new at 0x29f2b18>[ceph_deploy.cli][INFO ] verbose : False[ceph_deploy.cli][INFO ] overwrite_conf : False[ceph_deploy.cli][INFO ] quiet : False[ceph_deploy.cli][INFO ] cd_conf : <ceph_deploy.conf.cephdeploy.Conf instance at 0x2a15a70>[ceph_deploy.cli][INFO ] cluster : ceph[ceph_deploy.cli][INFO ] ssh_copykey : True[ceph_deploy.cli][INFO ] mon : ['node1', 'node2', 'node3'][ceph_deploy.cli][INFO ] public_network : None[ceph_deploy.cli][INFO ] ceph_conf : None[ceph_deploy.cli][INFO ] cluster_network : None[ceph_deploy.cli][INFO ] default_release : False[ceph_deploy.cli][INFO ] fsid : None[ceph_deploy.new][DEBUG ] Creating new cluster named ceph[ceph_deploy.new][INFO ] making sure passwordless SSH succeeds[node1][DEBUG ] connected to host: node0[node1][INFO ] Running command: ssh -CT -o BatchMode=yes node1[node1][DEBUG ] connection detected need for sudo[node1][DEBUG ] connected to host: node1[node1][DEBUG ] detect platform information from remote host[node1][DEBUG ] detect machine type[node1][DEBUG ] find the location of an executable[node1][INFO ] Running command: sudo /usr/sbin/ip link show[node1][INFO ] Running command: sudo /usr/sbin/ip addr show[node1][DEBUG ] IP addresses found: ['192.168.92.101', '192.168.1.102', '192.168.122.1'][ceph_deploy.new][DEBUG ] Resolving host node1[ceph_deploy.new][DEBUG ] Monitor node1 at 192.168.92.101[ceph_deploy.new][INFO ] making sure passwordless SSH succeeds[node2][DEBUG ] connected to host: node0[node2][INFO ] Running command: ssh -CT -o BatchMode=yes node2[node2][DEBUG ] connection detected need for sudo[node2][DEBUG ] connected to host: node2[node2][DEBUG ] detect platform information from remote host[node2][DEBUG ] detect machine type[node2][DEBUG ] find the location of an executable[node2][INFO ] Running command: sudo /usr/sbin/ip link show[node2][INFO ] Running command: sudo /usr/sbin/ip addr show[node2][DEBUG ] IP addresses found: ['192.168.1.103', '192.168.122.1', '192.168.92.102'][ceph_deploy.new][DEBUG ] Resolving host node2[ceph_deploy.new][DEBUG ] Monitor node2 at 192.168.92.102[ceph_deploy.new][INFO ] making sure passwordless SSH succeeds[node3][DEBUG ] connected to host: node0[node3][INFO ] Running command: ssh -CT -o BatchMode=yes node3[node3][DEBUG ] connection detected need for sudo[node3][DEBUG ] connected to host: node3[node3][DEBUG ] detect platform information from remote host[node3][DEBUG ] detect machine type[node3][DEBUG ] find the location of an executable[node3][INFO ] Running command: sudo /usr/sbin/ip link show[node3][INFO ] Running command: sudo /usr/sbin/ip addr show[node3][DEBUG ] IP addresses found: ['192.168.122.1', '192.168.1.104', '192.168.92.103'][ceph_deploy.new][DEBUG ] Resolving host node3[ceph_deploy.new][DEBUG ] Monitor node3 at 192.168.92.103[ceph_deploy.new][DEBUG ] Monitor initial members are ['node1', 'node2', 'node3'][ceph_deploy.new][DEBUG ] Monitor addrs are ['192.168.92.101', '192.168.92.102', '192.168.92.103'][ceph_deploy.new][DEBUG ] Creating a random mon key...[ceph_deploy.new][DEBUG ] Writing monitor keyring to ceph.mon.keyring...[ceph_deploy.new][DEBUG ] Writing initial config to ceph.conf...[ceph@node0 cluster]$

查看生成的文件

[ceph@node0 cluster]$ lsceph.conf ceph.log ceph.mon.keyring

查看ceph的配置文件，Node1节点都变为了控制节点

[ceph@node0 cluster]$ cat ceph.conf[global]fsid = 3c9892d0-398b-4808-aa20-4dc622356bd0mon_initial_members = node1, node2, node3mon_host = 192.168.92.111,192.168.92.112,192.168.92.113auth_cluster_required = cephxauth_service_required = cephxauth_client_required = cephxfilestore_xattr_use_omap = true[ceph@node0 my-cluster]$

5.2.1 修改副本数目

修改默认的副本数为2，即ceph.conf，使osd_pool_default_size的值为2。如果该行，则添加。

[ceph@node0 cluster]$ grep "osd_pool_default_size" ./ceph.confosd_pool_default_size = 2[ceph@node0 cluster]$

5.2.2 网络不唯一的处理

如果IP不唯一，即除ceph集群使用的网络外，还有其他的网络IP。

比如：

eno16777736: 192.168.175.100

eno50332184: 192.168.92.110

virbr0: 192.168.122.1

那么就需要在ceph.conf配置文档[global]部分增加参数public network参数：

public_network = {ip-address}/{netmask}

如：

public_network = 192.168.92.0/6789

5.3 安装ceph

管理节点节点用ceph-deploy工具向各个节点安装ceph：

ceph-deploy install {ceph-node}[{ceph-node} ...]

或者本地

ceph-deploy install {ceph-node}[{ceph-node} ...] --local-mirror=/opt/ceph-repo --no-adjust-repos --release=jewel

如：

[ceph@node0 cluster]$ ceph-deploy install node0 node1 node2 node3[ceph@node0 cluster]$ ceph-deploy install node0 node1 node2 node3[ceph_deploy.conf][DEBUG ] found configuration file at: /home/ceph/.cephdeploy.conf[ceph_deploy.cli][INFO ] Invoked (1.5.34): /usr/bin/ceph-deploy install node0 node1 node2 node3[ceph_deploy.cli][INFO ] ceph-deploy options:[ceph_deploy.cli][INFO ] verbose : False[ceph_deploy.cli][INFO ] testing : None[ceph_deploy.cli][INFO ] cd_conf : <ceph_deploy.conf.cephdeploy.Conf instance at 0x2ae0560>[ceph_deploy.cli][INFO ] cluster : ceph[ceph_deploy.cli][INFO ] dev_commit : None[ceph_deploy.cli][INFO ] install_mds : False[ceph_deploy.cli][INFO ] stable : None[ceph_deploy.cli][INFO ] default_release : False[ceph_deploy.cli][INFO ] username : None[ceph_deploy.cli][INFO ] adjust_repos : True[ceph_deploy.cli][INFO ] func : <function install at 0x2a53668>[ceph_deploy.cli][INFO ] install_all : False[ceph_deploy.cli][INFO ] repo : False[ceph_deploy.cli][INFO ] host : ['node0', 'node1', 'node2', 'node3'][ceph_deploy.cli][INFO ] install_rgw : False[ceph_deploy.cli][INFO ] install_tests : False[ceph_deploy.cli][INFO ] repo_url : None[ceph_deploy.cli][INFO ] ceph_conf : None[ceph_deploy.cli][INFO ] install_osd : False[ceph_deploy.cli][INFO ] version_kind : stable[ceph_deploy.cli][INFO ] install_common : False[ceph_deploy.cli][INFO ] overwrite_conf : False[ceph_deploy.cli][INFO ] quiet : False[ceph_deploy.cli][INFO ] dev : master[ceph_deploy.cli][INFO ] local_mirror : None[ceph_deploy.cli][INFO ] release : None[ceph_deploy.cli][INFO ] install_mon : False[ceph_deploy.cli][INFO ] gpg_url : None[ceph_deploy.install][DEBUG ] Installing stable version jewel on cluster ceph hosts node0 node1 node2 node3[ceph_deploy.install][DEBUG ] Detecting platform for host node0 ...[node0][DEBUG ] connection detected need for sudo[node0][DEBUG ] connected to host: node0[node0][DEBUG ] detect platform information from remote host[node0][DEBUG ] detect machine type[ceph_deploy.install][INFO ] Distro info: CentOS Linux 7.2.1511 Core[node0][INFO ] installing Ceph on node0[node0][INFO ] Running command: sudo yum clean all[node0][DEBUG ] Loaded plugins: fastestmirror, langpacks, priorities[node0][DEBUG ] Cleaning repos: Ceph Ceph-noarch base ceph-source epel extras updates[node0][DEBUG ] Cleaning up everything[node0][DEBUG ] Cleaning up list of fastest mirrors[node0][INFO ] Running command: sudo yum -y install epel-release[node0][DEBUG ] Loaded plugins: fastestmirror, langpacks, priorities[node0][DEBUG ] Determining fastest mirrors[node0][DEBUG ] * epel: mirror01.idc.hinet.net[node0][DEBUG ] 25 packages excluded due to repository priority protections[node0][DEBUG ] Package epel-release-7-7.noarch already installed and latest version[node0][DEBUG ] Nothing to do[node0][INFO ] Running command: sudo yum -y install yum-plugin-priorities[node0][DEBUG ] Loaded plugins: fastestmirror, langpacks, priorities[node0][DEBUG ] Loading mirror speeds from cached hostfile[node0][DEBUG ] * epel: mirror01.idc.hinet.net[node0][DEBUG ] 25 packages excluded due to repository priority protections[node0][DEBUG ] Package yum-plugin-priorities-1.1.31-34.el7.noarch already installed and latest version[node0][DEBUG ] Nothing to do[node0][DEBUG ] Configure Yum priorities to include obsoletes[node0][WARNIN] check_obsoletes has been enabled for Yum priorities plugin[node0][INFO ] Running command: sudo rpm --import https://download.ceph.com/keys/release.asc[node0][INFO ] Running command: sudo rpm -Uvh --replacepkgs https://download.ceph.com/rpm-jewel/el7/noarch/ceph-release-1-0.el7.noarch.rpm[node0][DEBUG ] Retrieving https://download.ceph.com/rpm-jewel/el7/noarch/ceph-release-1-0.el7.noarch.rpm[node0][DEBUG ] Preparing... ########################################[node0][DEBUG ] Updating / installing...[node0][DEBUG ] ceph-release-1-1.el7 ########################################[node0][WARNIN] ensuring that /etc/yum.repos.d/ceph.repo contains a high priority[node0][WARNIN] altered ceph.repo priorities to contain: priority=1[node0][INFO ] Running command: sudo yum -y install ceph ceph-radosgw[node0][DEBUG ] Loaded plugins: fastestmirror, langpacks, priorities[node0][DEBUG ] Loading mirror speeds from cached hostfile[node0][DEBUG ] * epel: mirror01.idc.hinet.net[node0][DEBUG ] 25 packages excluded due to repository priority protections[node0][DEBUG ] Package 1:ceph-10.2.2-0.el7.x86_64 already installed and latest version[node0][DEBUG ] Package 1:ceph-radosgw-10.2.2-0.el7.x86_64 already installed and latest version[node0][DEBUG ] Nothing to do[node0][INFO ] Running command: sudo ceph --version[node0][DEBUG ] ceph version 10.2.2 (45107e21c568dd033c2f0a3107dec8f0b0e58374)….
