（1）硬件環境：
- 筆記本一台，CPU、內存和磁盤空間足夠
- 筆記本上建立一塊環回接口用於分布式存儲管理網絡
（2）軟件環境：
- 筆記本安裝 Win10 操作系統
- 虛擬環境：VMware Workstation 14 Pro
使用VMnet2和VMnet3 作為分布式存儲 public和cluster網絡
- 虛擬機操作系統：SLES15SP1 企業版操作系統
1、網絡

2、磁盤
每個節點系統有2塊 OSD 盤和1塊 NVME 磁盤
1 # lsblk 2 NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT 3 sda 8:0 0 20G 0 disk # 操作系統盤 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 數據盤 9 sdc 8:32 0 10G 0 disk # osd 數據盤 10 nvme0n1 259:0 0 20G 0 disk # wal db
二、操作系統初始化安裝
1、臨時IP地址設置
1 ip link set eth0 up 2 ip addr add 172.200.50.50/24 dev eth0
連接上了設置永久地址
yast lan list
yast lan edit id=0 ip=192.168.2.40 netmask=255.255.255.0
2、設置bash環境變量和別名
# 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
復制該內容進去
#! /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. #

5、安裝基本軟件 (所有節點和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、關閉IPV6 (所有節點和admin)
# vim /etc/sysctl.conf net.ipv6.conf.all.disable_ipv6 = 1 # 關閉 IPV6 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1 vm.min_free_kbytes = 2097152 # 128GB的RAM，系統預留2GB kernel.pid_max = 4194303 # 線程數設置最大
執行生效
# sysctl -p
7、調整網絡優化參數 (所有節點和admin)
# tuned-adm profile throughput-performance # tuned-adm active # systemctl start tuned.service # systemctl enable tuned.service
8、編輯hosts文件 (所有節點和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、執行更新操作系統，並重啟 (所有節點和admin)
# zypper ref # zypper -n update # reboot
三、安裝Storage6集群
1、安裝 salt（admin節點）
zypper -n in deepsea systemctl restart salt-master.service systemctl enable salt-master.service systemctl status salt-master.service
osd節點 和 admin節點
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
接受所有請求（admin節點）
salt-key salt-key --accept-all salt-key salt '*' test.ping
2、Admin節點，配置NTP服務
如果沒有ntp服務器，默認以admin節點為ntp server
Admin節點：
# vim /etc/chrony.conf # Sync to local clock # 添加本地時鍾源 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、修改組（admin節點）
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、遠程連接終端監控（admin節點）
該程序監控提供一個詳細的，實時的可視化操作行為，當在執行運行salt-run state.orch時，監控執行期間運行了什么
# deepsea monitor
5、更新補丁，並收集硬件信息（admin節點）
salt-run state.orch ceph.stage.0 salt-run state.orch ceph.stage.1
報錯信息可忽略
No minions matched the target. No command was sent, no jid was assigned. No minions matched the target. No command was sent, no jid was assigned. [ERROR ] Exception during resolving address: [Errno 2] Host name lookup failure [ERROR ] Exception during resolving address: [Errno 2] Host name lookup failure [WARNING ] /usr/lib/python3.6/site-packages/salt/grains/core.py:2827: DeprecationWarning: This server_id is computed nor by Adler32 neither by CRC32. Please use "server_id_use_crc" option and define algorithm youprefer ( default "Adler32"). The server_id will be computed withAdler32 by default.

6、查看網絡配置文件（admin節點）
# 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節點）
（1）模板文件，復制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）編輯模板文件（admin節點）
# 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 # 定義為 storage 角色 role-storage/cluster/node00*.sls
（3）執行stage2命令 （admin節點）
# salt-run state.orch ceph.stage.2 # salt '*' pillar.items # 查看設置是否正確
尤其是NTP，role 角色定義，public network 網絡 是否定義正確
public_network: 192.168.2.0/24 roles: - mon - mgr - storage time_server: admin.example.com
（4）如果3個節點需要修改 （admin節點）
由於測試環境，只用到3台OSD節點，官方建議生產環境必須是4台節點或以上
# 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、定義和創建 OSD 磁盤
（1）備份配置文件
# cp /srv/salt/ceph/configuration/files/drive_groups.yml /srv/salt/ceph/configuration/files/drive_groups.yml.bak
（2）查看OSD節點磁盤情況（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）編輯配置文件
# vim /srv/salt/ceph/configuration/files/drive_groups.yml drive_group_hdd_nvme: # 目標為 storage角色節點 target: 'I@roles:storage' data_devices: size: '9GB:12GB' # 數據設備按照磁盤大小來區分，9G到12G之間 db_devices: rotational: 0 # 非機械設備 SSD or NVME block_db_size: '2G' # 指定 db大小為2GB （大小按實際情況）
（4）顯示OSD配置報告
可以清楚的看到一塊nvme0n1作為BlueStore的DB設備，2G大小，分割成2個LV對應2塊OSD數據磁盤。
# 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：如果磁盤無法識別請使用如下命令格式化，不能有GPT分區
# ceph-volume lvm zap /dev/xx
# ceph-volume lvm zap /dev/xx --destroy
（5）運行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倉庫、安裝 Haproxy (admin節點)
# 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 # 定義bind綁定，監聽那個套接字，如果是node001作為admin節點，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) 啟動haproxy服務
# systemctl start haproxy.service
# systemctl enable haproxy.service
# systemctl status haproxy.service
4) 查看dashboard管理員密碼：
# salt-call grains.get dashboard_creds local: ---------- admin: 9KyIXZSrdW
5）windows主機添加域名解析
C:\Windows\System32\drivers\etc\host 127.0.0.1 localhost 172.200.50.39 admin.example.com
6）訪問SES6 Dashboard頁面
http://172.200.50.39:8443/#/dashboard
