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
- 修改主机名称
hostnamectl set-hostname node00
hostnamectl set-hostname node01
hostnamectl set-hostname node02
- 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
- 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
- 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。
- 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
- 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 '

- 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
- SELinux设为禁用：
setenforce 0
永久生效：编辑 vi /etc/selinux/config修改：
SELINUX=disabled
正式安装
- 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：
- 创建目录
mkdir -p /opt/ceph/ceph-cluster && cd /opt/ceph/ceph-cluster
- 创建集群；
ceph-deploy new node00 node01 node02
会生成配置文件；
vi /opt/ceph/ceph-cluster/ceph.conf

public network是其公网IP（虚拟机是vmnet8的网卡IP）
- 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。
- 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：
- 同步管理信息

- 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
- 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
- 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
安装管理后台
- 开启dashboard模块
ceph mgr module enable dashboard
- 生成签名
ceph dashboard create-self-signed-cert
- 创建目录
mkdir mgr-dashboard&&cd mgr-dashboard
[root@node00 mgr-dashboard]# pwd
/opt/ceph/ceph-cluster/mgr-dashboard
- 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
- 启动dashboard
ceph mgr module disable dashboard
ceph mgr module enable dashboard
- 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
- 关闭HTTPS
ceph config set mgr mgr/dashboard/ssl false
- 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
- 设置管理用户与密码
ceph dashboard set-login-credentials admin admin
安装问题记录
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：
-
防火墙：
-
hosts配置和hostname 不一致
-
public_network配置问题
一些其他的文档说明是地址是public_network如下图：
