SUSE Ceph 快速部署

学习 SUSE Storage 系列文章

一、安装环境描述

整个环境采用VMware workstation搭建，一共5台虚拟机，所有虚拟机安装SLES15SP1系统，其中一台安装apache作为仓库使用，剩余4台用于搭建Storage6集群。

（1）硬件环境：

笔记本一台，CPU、内存和磁盘空间足够
笔记本上建立一块环回接口用于分布式存储管理网络

（2）软件环境：

笔记本安装 Win10 操作系统
虚拟环境：VMware Workstation 14 Pro

使用VMnet2和VMnet3 作为分布式存储 public和cluster网络

虚拟机操作系统：SLES15SP1 企业版操作系统

node002   192.168.2.42    172.200.50.42   192.168.3.42    MON

node003   192.168.2.43    172.200.50.43   192.168.3.43    MON

2、磁盘
每个节点系统有2块 OSD 盘和1块 NVME 磁盘

 # lsblk

 NAME            MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT

 sda               :       20G   disk              # 操作系统盘

 ├─sda1            :        1G   part /boot

 └─sda2            :       19G   part

   ├─vgoo-lvroot :       17G   lvm  /

   └─vgoo-lvswap :        2G   lvm  [SWAP]

 sdb               :      10G   disk              # osd 数据盘

 sdc               :      10G   disk              # osd 数据盘

 nvme0n1         :       20G   disk              # wal db

二、操作系统初始化安装

1、临时IP地址设置

 ip link set eth0 up

 ip addr add 172.200.50.50/ dev eth0

连接上了设置永久地址

yast lan list
yast lan edit id=0 ip=192.168.2.40 netmask=255.255.255.0

2、设置bash环境变量和别名

# vim /root/.bash_profile

alias cd..='cd ..'

alias dir='ls -l'

alias egrep='egrep --color=auto'

alias fgrep='fgrep --color=auto'

alias grep='grep --color=auto'

alias l='ls -alF'

alias la='ls -la'

alias ll='ls -l'

alias ls-l='ls -l'

3、配置after.local文件

touch /etc/init.d/after.local

chmod  /etc/init.d/after.local

复制该内容进去

#! /bin/sh

#

# Copyright (c)  SuSE LINUX Products GmbH, Germany.  All rights reserved.

#

# Author: Werner Fink,

#

# /etc/init.d/after.local

#

# script with local commands to be executed from init after all scripts

# of a runlevel have been executed.

#

# Here you should add things, that should happen directly after

# runlevel has been reached.

#

4、仓库配置(所有节点和admin)

10 | SUSE-Enterprise-Storage-6-Updates                  | SUSE-Enterprise-Storage-6-Updates

5、安装基本软件 (所有节点和admin)

zypper in -y -t pattern yast2_basis base

zypper in -y net-tools vim man sudo tuned irqbalance

zypper in -y ethtool rsyslog iputils less supportutils-plugin-ses

zypper in -y net-tools-deprecated tree wget

6、关闭IPV6 (所有节点和admin)

# vim /etc/sysctl.conf

net.ipv6.conf.all.disable_ipv6 =                  # 关闭 IPV6

net.ipv6.conf.default.disable_ipv6 =

net.ipv6.conf.lo.disable_ipv6 =

vm.min_free_kbytes =                        # 128GB的RAM，系统预留2GB

kernel.pid_max =                            # 线程数设置最大

执行生效

# sysctl -p

7、调整网络优化参数 (所有节点和admin)

# tuned-adm profile throughput-performance

# tuned-adm active

# systemctl start tuned.service

# systemctl enable tuned.service

8、编辑hosts文件 (所有节点和admin)

# vim /etc/hosts

192.168.2.39    admin.example.com admin

192.168.2.40    node001.example.com node001

192.168.2.41    node002.example.com node002

192.168.2.42    node003.example.com node003

9、执行更新操作系统，并重启 (所有节点和admin)

# zypper ref

# zypper -n update

# reboot

三、安装Storage6集群

1、安装 salt（admin节点）

zypper -n in deepsea

systemctl restart salt-master.service

systemctl enable salt-master.service

systemctl status salt-master.service

osd节点和 admin节点

zypper -n in salt-minion

sed -i '17i\master: 192.168.2.39' /etc/salt/minion

systemctl restart salt-minion.service

systemctl enable salt-minion.service

systemctl status salt-minion.service

接受所有请求（admin节点）

salt-key

salt-key --accept-all

salt-key

salt '*' test.ping

2、Admin节点，配置NTP服务
如果没有ntp服务器，默认以admin节点为ntp server
Admin节点：

# vim /etc/chrony.conf

# Sync to local clock        # 添加本地时钟源

server 127.0.0.1

allow 127.0.0.0/

allow 192.168.2.0/

allow 172.200.50.0/

local stratum

systemctl restart chronyd.service

systemctl enable chronyd.service

systemctl status chronyd.service

# chronyc sources

 Number of sources =

MS Name/IP address         Stratum Poll Reach LastRx Last sample

===============================================================================

^* 127.127.1.0                               +1461ns[+3422ns] +/-  166us

# chronyc -n sources -v

3、修改组（admin节点）

cp -p /srv/pillar/ceph/deepsea_minions.sls /tmp/

sed -i "4c # deepsea_minions: 'G@deepsea:*'" /srv/pillar/ceph/deepsea_minions.sls

sed -i "6c deepsea_minions: '*'" /srv/pillar/ceph/deepsea_minions.sls

4、远程连接终端监控（admin节点）

该程序监控提供一个详细的，实时的可视化操作行为，当在执行运行salt-run state.orch时，监控执行期间运行了什么

# deepsea monitor

5、更新补丁，并收集硬件信息（admin节点）

salt-run state.orch ceph.stage.

salt-run state.orch ceph.stage.
