node003   192.168.2.43    172.200.50.43   192.168.3.43    MON

2、磁盘每个系统有2块OSD盘，·1块NVME磁盘

 1 # lsblk 
 2 NAME            MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
 3 sda               8:0    0   20G  0 disk              # 操作系统盘
 4 ├─sda1            8:1    0    1G  0 part /boot
 5 └─sda2            8:2    0   19G  0 part 
 6   ├─vgoo-lvroot 254:0    0   17G  0 lvm  /
 7   └─vgoo-lvswap 254:1    0    2G  0 lvm  [SWAP]
 8 sdb               8:16   0   10G  0 disk              # osd 数据盘
 9 sdc               8:32   0   10G  0 disk              # osd 数据盘
10 nvme0n1         259:0    0   20G  0 disk              # wal db

二、操作系统初始化安装

1、临时IP地址设置

1 ip link set eth0 up
2 ip addr add 172.200.50.50/24 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 744 /etc/init.d/after.local

复制该内容进去

#! /bin/sh
#
# Copyright (c) 2010 SuSE LINUX Products GmbH, Germany.  All rights reserved.
#
# Author: Werner Fink, 2010
#
# /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 = 1                 # 关闭 IPV6
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
vm.min_free_kbytes = 2097152                       # 128GB的RAM，系统预留2GB
kernel.pid_max = 4194303                           # 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 127.0.0.0/8
allow 192.168.2.0/24
allow 172.200.50.0/24
local stratum 10

systemctl restart chronyd.service
systemctl enable chronyd.service
systemctl status chronyd.service

# chronyc sources      
210 Number of sources = 1
MS Name/IP address         Stratum Poll Reach LastRx Last sample               
===============================================================================
^* 127.127.1.0                  12   6    37    23  +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.0
salt-run state.orch ceph.stage.1

报错信息可忽略

6、查看网络配置文件（admin节点）

# vim /srv/pillar/ceph/proposals/config/stack/default/ceph/cluster.yml
 cluster_network: 192.168.3.0/24
 fsid: 10aca2da-ead5-438d-b104-da37870b50b8
 public_network: 192.168.2.0/24

7、配置集群policy.cfg文件（admin节点）（1）模板文件，复制policy.cfg-rolebased模板

# ll /usr/share/doc/packages/deepsea/examples/
total 12
-rw-r--r-- 1 root root 329 Jun 13 16:00 policy.cfg-generic
-rw-r--r-- 1 root root 489 Jun 13 16:00 policy.cfg-regex
-rw-r--r-- 1 root root 577 Jun 13 16:00 policy.cfg-rolebased

# cp /usr/share/doc/packages/deepsea/examples/policy.cfg-rolebased /srv/pillar/ceph/proposals/policy.cfg

（2）编辑模板文件（admin节点）

# vim /srv/pillar/ceph/proposals/policy.cfg
## Cluster Assignment
cluster-ceph/cluster/*.sls

## Roles
# ADMIN  
role-master/cluster/admin*.sls
role-admin/cluster/admin*.sls

# Monitoring
role-prometheus/cluster/admin*.sls
role-grafana/cluster/admin*.sls

# MON
role-mon/cluster/node00[1-3]*.sls

# MGR (mgrs are usually colocated with mons)
role-mgr/cluster/node00[1-3]*.sls

# COMMON
config/stack/default/global.yml
config/stack/default/ceph/cluster.yml

# Storage   # 定义为 storage 角色
role-storage/cluster/node00*.sls

（3）执行stage2命令（admin节点）

# salt-run state.orch ceph.stage.2
# salt '*' pillar.items    # 查看设置是否正确

尤其是NTP，role 角色定义，public network 网络是否定义正确

    public_network:
        192.168.2.0/24
    roles:
        - mon
        - mgr
        - storage
    time_server:
        admin.example.com

（4）如果3个节点需要修改（admin节点）由于测试环境，只用到3台OSD节点，官方建议生产环境必须是4台节点或以上

# sed -i 's/if (not self.in_dev_env and len(storage) < 4/if (not self.in_dev_env and len(storage) < 2/g' /srv/modules/runners/validate.py

8、定义和创建 OSD 磁盘（1）备份配置文件

# cp /srv/salt/ceph/configuration/files/drive_groups.yml /srv/salt/ceph/configuration/files/drive_groups.yml.bak

（2）查看OSD节点磁盘情况（node001,node002,node003)

# ceph-volume inventory
 stderr: blkid: error: /dev/sr0: No medium found

Device Path               Size         rotates available Model name
/dev/nvme0n1              20.00 GB     False   True      VMware Virtual NVMe Disk
/dev/sdb                  10.00 GB     True    True      VMware Virtual S
/dev/sdc                  10.00 GB     True    True      VMware Virtual S
/dev/sda                  20.00 GB     True    False     VMware Virtual S
/dev/sr0                  1024.00 MB   True    False     VMware SATA CD01

（3）编辑配置文件

# vim /srv/salt/ceph/configuration/files/drive_groups.yml
drive_group_hdd_nvme:             # 目标为 storage角色节点
  target: 'I@roles:storage'
  data_devices:
    size: '9GB:12GB'              # 数据设备按照磁盘大小来区分，9G到12G之间
  db_devices:
    rotational: 0                 # 非机械设备 SSD or NVME
  block_db_size: '2G'             # 指定 db大小为2GB  （大小按实际情况）

（4）显示OSD配置报告

可以清楚的看到一块nvme0n1作为BlueStore的DB设备，2G大小，分割成2个LV对应2块OSD数据磁盘。

# salt-run disks.report
  node003.example.com:
      |_
        - 0
        -
          Total OSDs: 2
          
          Solid State VG:
            Targets:   block.db                  Total size: 19.00 GB                 
            Total LVs: 2                         Size per LV: 1.86 GB                  
            Devices:   /dev/nvme0n1
          
            Type            Path                LV Size         % of device
          ----------------------------------------------------------------
            [data]          /dev/sdb            9.00 GB         100.0%
            [block.db]      vg: vg/lv           1.86 GB         10%
          ----------------------------------------------------------------
            [data]          /dev/sdc            9.00 GB         100.0%
            [block.db]      vg: vg/lv           1.86 GB         10%

注意：如果磁盘无法识别请使用如下命令格式化，不能有GPT分区

# ceph-volume lvm zap /dev/xx 
# ceph-volume lvm zap /dev/xx --destroy

（5）运行stage3 stage4

# salt-run state.orch ceph.stage.3
# salt-run state.orch ceph.stage.4

四、配置HAproxy和Dashboard

1、添加SUSE HA仓库、安装 Haproxy (admin节点)

# zypper ar http://172.200.50.19/repo/SUSE/Products/SLE-Product-HA/15-SP1/x86_64/product/ SLE-Products-HA-SLES15-SP1-Pool
# zypper -n in haproxy

2、配置

# vim /etc/haproxy/haproxy.cfg
    ……
frontend http_web
    option tcplog
    bind 0.0.0.0:8443                 # 定义bind绑定，监听那个套接字，如果是node001作为admin节点，改成9443
    mode tcp
    default_backend dashboard

backend dashboard
    mode tcp
    option log-health-checks
    option httpchk GET /
    http-check expect status 200
    server mgr1 172.200.50.40:8443 check ssl verify none
    server mgr2 172.200.50.41:8443 check ssl verify none
    server mgr3 172.200.50.42:8443 check ssl verify none

3) 启动haproxy服务

# systemctl start haproxy.service
# systemctl enable haproxy.service
# systemctl status haproxy.service

4) 查看dashboard管理员密码：

# salt-call grains.get dashboard_creds
local:
    ----------
    admin:
        9KyIXZSrdW

5）windows主机添加域名解析

C:\Windows\System32\drivers\etc\host
127.0.0.1 localhost
172.200.50.39 admin.example.com

6）访问SES6 Dashboard页面

http://172.200.50.39:8443/#/dashboard
