（5）深入理解 DeepSea 和 Salt 部署工具 - Storage6
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
1、网络

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)

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.
