Ceph集群搭建记录

环境准备

基础环境

node00

192.168.247.144

node00

node01

192.168.247.135

node01

node02

192.168.247.143

node02

vmare在分配IP没有连续，没有关系继续吧

配置免密登录

  1. 修改主机名称

    hostnamectl set-hostname node00
    hostnamectl set-hostname node01
    hostnamectl set-hostname node02

  2. 编辑hosts文件

    [root@linux30 ~]# vi /etc/hosts
    192.168.247.144 node00
    192.168.247.135 node01
    192.168.247.143 node02

  3. 官方建议不用系统内置用户， 创建名为ceph_user用户， 密码也设为123456：

    useradd -d /home/ceph_user -m ceph_user
    passwd ceph_user

    设置root 权限

    echo "ceph_user ALL = (root) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/ceph_user
    sudo chmod 0440 /etc/sudoers.d/ceph_user

  4. 生成密钥：切换用户： su ceph_user 执行ssh-keygen，一直按默认提示点击生成RSA密钥信息。

  5. 分发密钥至各机器节点

    ssh-copy-id ceph_user@node00
    ssh-copy-id ceph_user@node01
    ssh-copy-id ceph_user@node02

  6. 修改管理节点上的 ~/.ssh/config 文件， 简化SSH远程连接时的输入信息：管理节点是会有root和ceph_user多个用户， ssh远程连接默认会以当前用户身份进行登陆， 如果我们是root身份进行远程连接， 还是需要输入密码， 我们想简化， 该怎么处理？

    su root
    vim /root/.ssh/config

复制一下内容即可

Host node00
   Hostname node00
   User ceph_user
Host node01
   Hostname node01
   User ceph_user
Host node02
   Hostname node02
   User ceph_user

注意修改文件权限， 不能采用777最大权限：

chmod 600 ~/.ssh/config

NTP时间工具同步

# 下载
yum install ntp ntpdate ntp-doc -y

# 确保时区是正确， 设置开机启动：
systemctl enable ntpd

# 将时间每隔1小时自动校准同步。编辑 vi /etc/rc.d/rc.local 追加：
echo "/usr/sbin/ntpdate ntp1.aliyun.com > /dev/null 2>&1; /sbin/hwclock -w" >> /etc/rc.d/rc.local

# 配置定时任务,  执行crontab -e 加入
crontab -e 0 */1 * * * ntpdate ntp1.aliyun.com > /dev/null 2>&1; /sbin/hwclock -w

ceph的镜像加速源头设置

rpm -ivh https://mirrors.aliyun.com/ceph/rpm-mimic/el7/noarch/ceph-release-1-1.el7.noarch.rpm

yum install epel-release

yum install ceph-deploy python-setuptools python2-subprocess32

并配置镜像加速源

echo '
[Ceph]
name=Ceph packages for $basearch
baseurl=https://mirrors.tuna.tsinghua.edu.cn/ceph/rpm-mimic/el7/x86_64/
enabled=1
gpgcheck=1
type=rpm-md
gpgkey=https://download.ceph.com/keys/release.asc

[Ceph-noarch]
name=Ceph noarch packages
# 官方源
#baseurl=http://download.ceph.com/rpm-mimic/el7/noarch
# 清华源
baseurl=https://mirrors.tuna.tsinghua.edu.cn/ceph/rpm-mimic/el7/noarch/
enabled=1
gpgcheck=1
type=rpm-md
gpgkey=https://download.ceph.com/keys/release.asc

[ceph-source]
name=Ceph source packages
baseurl=https://mirrors.tuna.tsinghua.edu.cn/ceph/rpm-mimic/el7/SRPMS/
enabled=1
gpgcheck=1
type=rpm-md
gpgkey=https://download.ceph.com/keys/release.asc' > /etc/yum.repos.d/ceph.repo

  1. 开放端口， 非生产环境， 可以直接禁用防火墙：

    systemctl stop firewalld.service
    systemctl disable firewalld.service

  2. SELinux设为禁用：

    setenforce 0

永久生效：编辑 vi /etc/selinux/config修改：

SELINUX=disabled

  1. ceph-deploy 工具安装；主节点安装：

    yum update && yum -y install ceph ceph-deploy

也可通过如下方式安装：

  1. 创建目录

    mkdir -p /opt/ceph/ceph-cluster && cd /opt/ceph/ceph-cluster

  2. 创建集群；

    ceph-deploy new node00 node01 node02

会生成配置文件；

vi /opt/ceph/ceph-cluster/ceph.conf


[global]
fsid = 7d75db39-d457-4764-b7d2-1b48645b2781
mon_initial_members = linux30, linux31, linux32
mon_host = 192.168.10.30,192.168.10.31,192.168.10.32
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx

# 公网网络
public network = 192.168.247.100/24
# 设置pool池默认分配数量 默认副本数为3
osd pool default size = 2
# 容忍更多的时钟误差
mon clock drift allowed = 2
mon clock drift warn backoff = 30
# 允许删除pool
mon_allow_pool_delete = true
[mgr]
# 开启WEB仪表盘
mgr modules = dashboard

public network是其公网IP（虚拟机是vmnet8的网卡IP）

  1. 节点部署

    ceph-deploy install node00 node01 node02 --no-adjust-repos

--no-adjust-repos使用该命令可以实现加速效果；并且不改变镜像源。

  1. 初始monitor信息：

    ceph-deploy mon create-initial

    ceph-deploy --overwrite-conf mon create-initial

执行完之后，本地目录下会生成若干keyring结尾的密钥文件；如下图：

  1. 同步管理信息

    ceph-deploy admin node00 node01 node02

  2. 安装mgr(管理守护进程)， 大于12.x版本需安装， 我们装的是最新版，需执行：

    ceph-deploy mgr create node00 node01 node02

  3. 安装OSD(对象存储设备）并且完成挂载

fdisk -l查看加挂磁盘

加挂节点：

ceph-deploy osd create --data /dev/sdb node00
ceph-deploy osd create --data /dev/sdb node01
ceph-deploy osd create --data /dev/sdb node02

  1. 测试安装情况：

    ceph-s

ceph config set mgr mgr/dashboard/server_addr 192.168.247.146
ceph config set mgr mgr/dashboard/server_port 18843

ceph config set mgr mgr/dashboard/server_addr node01

  1. 开启dashboard模块

    ceph mgr module enable dashboard

  2. 生成签名

    ceph dashboard create-self-signed-cert

  3. 创建目录

    mkdir mgr-dashboard&&cd mgr-dashboard

[root@node00 mgr-dashboard]# pwd

/opt/ceph/ceph-cluster/mgr-dashboard

  1. 生成密钥对

    cd /opt/ceph/ceph-cluster/mgr-dashboard
    openssl req -new -nodes -x509 -subj "/O=IT/CN=ceph-mgr-dashboard" -days 3650 -keyout dashboard.key -out dashboard.crt -extensions v3_ca

[root@linux30 mgr-dashboard]# ll

total 8

-rw-rw-r-- 1 ceph_user ceph_user 1155 Jul 14 02:26 dashboard.crt

-rw-rw-r-- 1 ceph_user ceph_user 1704 Jul 14 02:26 dashboard.key

  1. 启动dashboard

    ceph mgr module disable dashboard
    ceph mgr module enable dashboard

  2. 设置IP与PORT

    ceph config set mgr mgr/dashboard/server_addr 192.168.247.146
    ceph config set mgr mgr/dashboard/server_port 18843

  3. 关闭HTTPS

    ceph config set mgr mgr/dashboard/ssl false

  4. 查看服务信息

    [root@node00 ceph-cluster]# ceph mgr services
    {
    "dashboard": "http://192.168.247.146:18843/"
    }

    ceph config set mgr mgr/dashboard/server_addr node00

  5. 设置管理用户与密码

    ceph dashboard set-login-credentials admin admin

  6. 访问 http://192.168247.146:18843/

ceph -s出现问题：

可能是时间同步问题，

ystemctl start ntpd     #新增的节点没有启动ntpd

systemctl  restart  ceph-mon.target

systemctl  restart  ceph-mon.target

ceph-deploy mon相关问题汇总：

ceph-deploy mon出现mon.node40 monitor is not yet in quorum, tries left: 5错误：

错误的含义是：mon.node40 监视器尚未达到仲裁状态，经过多轮尝试后失败。

网络参考可能原因：

  1. 防火墙：

  2. hosts配置和hostname 不一致

  3. public_network配置问题

    一些其他的文档说明是地址是 public_network如下图：
