集群规划
本案例通过ceph-deploy方式部署
| 主机名 | 配置 | 外网IP / 内网IP | 角色 | 系统版本 |

基础优化
1. 主机名规划:
ip=`ip a |grep -w "global eth0" |awk -F ‘inet ‘ ‘{print$2}‘|awk -F ‘/‘ ‘{print$1}‘`
Ipformat=`echo ${ip//./-}`
startwith="ceph"
hostname="$startwith-$Ipformat"
echo $hostname
hostnamectl set-hostname $hostname
2. 关闭selinux和网卡s管理：
setenforce 0
getenforce
sed -i ‘s#^SELINUX=.*$#SELINUX=disabled#g‘ /etc/selinux/config
systemctl stop NetworkManager.service
systemctl disable NetworkManager.service
systemctl stop firewalld
systemctl disable firewalld
2. 安装ceph源配置:
yum install -y epel-release
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
#ceph源
rpm -ivh https://mirrors.aliyun.com/ceph/rpm-mimic/el7/noarch/ceph-release-1-1.el7.noarch.rpm
yum makecache
3. 时间同步[内网时间同步]
ceph-admin 作为时间服务器，其他服务器进行同步
3.1. 安装时间同步[全部执行]：
[ceph@ceph-mon01 ~]$ exit #这里是从ceph用户退回root用户
[root@ceph-mon01 ~]# yum install -y ntp
[root@ceph-mon01 ~]# systemctl start ntpd
[root@ceph-mon01 ~]# systemctl enable ntpd
[root@ceph-mon01 ~]# timedatectl set-timezone Asia/Shanghai #时区设置为上海
# 时间服务器配置[ 为了方便全部使用阿里云时间服务器 每台都配置，如果内网就做内网时间授权]：
sed -i "s/^server 0.*/server ntp1.aliyun.com/g" /etc/ntp.conf
sed -i "s/^server 1/#&/g" /etc/ntp.conf
sed -i "s/^server 2/#&/g" /etc/ntp.conf
sed -i "s/^server 3/#&/g" /etc/ntp.conf
#重启ntp：
systemctl restart ntpd
ntpq -pn
#查看时间同步： ntpq -pn
[root@ceph-admin ~]# ntpq -pn
remote refid st t when poll reach delay offset jitter

*120.25.115.20 10.137.53.7 2 u 1 64 1 36.838 5.072 0.622
#通过计划任务来同步外网时间[可选]
sudo echo ‘*/5 * * * * /usr/sbin/ntpd -pn‘ >>/var/spool/cron/root
sudo systemctl restart crond.service
crontab -l
#3.2 添加文件描述符[所有服务器]
cat >> /etc/security/limits.conf <<EOF

sysctl -p
#1.4配置hosts:
192.168.3.101 ceph-mon01.example ceph-mon01 ceph-osd01 ceph-deploy
192.168.3.102 ceph-mon02.example ceph-mon02 ceph-osd02

192.168.3.107 ceph-node02.example ceph-node02
#1.5 配置主机名:
#按照host文件设置主机名，切记一定要设置为 域名类型的 如： ceph-mon01.example 否则会出现无法安装的问题
#如 192.168.3.101 设置如下，其他的自己都配置一下，这里不一一列举
hostnamectl set-hostname ceph-mon01.example
bash
# 2. sudo权限配置:
# 2.1 所有用户[所有机器]:
groupadd -r -g 2001 ceph && useradd -r -m -s /bin/bash -u 2001 -g 2001 ceph
echo ‘123456‘|passwd --stdin ceph
# 2.2 sudo配置[所有机器]:
echo ‘ceph ALL=(root) NOPASSWD:ALL‘ |sudo tee /etc/sudoers.d/ceph
chmod 0440 /etc/sudoers.d/ceph
cat /etc/sudoers.d/ceph
# 3.1 免密配置 [应该使用内网IP来做免密，使用部署机配置对集群主机的免密 ，该操作在部署机切换到ceph执行]
#定义变量
su - ceph
CEPH=(172.16.1.101 172.16.1.102 172.16.1.103 172.16.1.104 172.16.1.105 172.16.1.106 172.16.1.107)
#配置免密
ssh-keygen
for ip in ${CEPH[@]}; do
ssh-copy-id -o StrictHostKeyChecking=no ${ip}
done
# 2.4验证免密
su - ceph
for ip in ${CEPH[@]}; do
ssh ${ip} ‘hostname‘
done
初始化集群:
#1. node1 作为ceph-deploy部署节点[所有节点都安装，此命令请使用root用户执行]：
# 这里如果不安装，后面初始化也会帮你装，但是会浪费很多时间
su - root
yum install -y ceph-deploy python-setuptools python2-subprocess3
#2. 切换到ceph用户进行初始化：
[root@ceph-node01 ~]# su - ceph
[ceph@ceph-mon01 ~]$ mkdir ceph-cluster
[ceph@ceph-mon01 ~]$ cd ceph-cluster/
#[ubuntu需要额外安装python2.7,centos不用]
#3. 初始化ceph集群:
# 设置得mon节点是 node02 需要查看主机名是什么 然后再通过主机名来安装
[root@ceph-node02 ~]# uname -n
ceph-node02
[ceph@ceph-node01 ceph-cluster]$ ceph-deploy --help
optional arguments:
--no-ssh-copykey do not attempt to copy SSH keys
--fsid FSID provide an alternate FSID for ceph.conf generation
--cluster-network CLUSTER_NETWORK #集群内部网络
--public-network PUBLIC_NETWORK #外部网络，给客户端访问的，能够上外网的
#参数解释：
#环境规划中，172.16.1.0/16网段是 --cluster-network 网络[仅内网访问]
# 192.168.3.0/24网段是 --public-network 网络[可上外网]
#部署mon

mon节点初始化
# 1. 知识扫盲:
#---------------------------------------------------------------------------#
#ceph-deploy工具命令扫盲：
ceph-deploy install #在远程主机安装ceph相关软件包，可通过--release来指定版本号
ceph-deploy new #创建一个新的集群
ceph-deploy rgw #管理RGW守护程序(RADOSGW,对象存储网关)
ceph-deploy mgr #管理MGR守护程序(ceph-mgr,ceph Manager DaemonCeph 管理器守护程序)
ceph-deploy mds #管理MDS守护程序(ceph metadata server，ceph源数据服务器)
ceph-deploy mon #管理MON守护程序(ceph-mon,ceph监视器)
gatherkeys #从指定获取提供新节点的验证keys，这些keys会在新的MON/OSD/MD加入的时候使用
ceph-deploy zap #擦除数据，并且创建文件系统分区(相当于格式化为ceph的文件系统)
ceph-deploy list #列出远端服务器的磁盘，列出远程服务器的osd
ceph-deploy osd #管理远端磁盘的，通常用于加入ceph集群，并作为什么样的数据类型
ceph-deploy repo #ceph的仓库
ceph-deploy config #拷贝ceph.conf的配置文件到远端主机[很少用]
ceph-deploy uninstall #删除远端ceph主机安装包，但会保留数据
ceph-deploy purge #删除包的同时删除所有数据
ceph-deploy purgedata #删除 /var/lib/ceph的所有数据
ceph-deploy forgetkey #删除本地主机所有的ceph验证key，包括 client,admin,monitor,bootstarp等认证key
ceph-deploy pkg #管理远端主机的安装包
ceph-deploy calamari #安装并配置一个calamari web节点，calamari是一个web监控平台
# 2. ceph mon节点部署:
mon节点部署[使用root安装]:
环境规划中：192.168.3.102,192.168.3.103,192.168.3.104 为mon节点
#确认环境信息中的mon节点：
[ceph@ceph-mon01 ceph-cluster]$ grep mon /etc/hosts
192.168.3.101 ceph-mon01.example ceph-mon01 ceph-osd01 ceph-deploy
192.168.3.102 ceph-mon02.example ceph-mon02 ceph-osd02
192.168.3.103 ceph-mon03.example ceph-mon03 ceph-osd03
#mon节点初始化注意事项:
#host文件中规划了3个mon节点，这里就写这3个节点的主机名就好
#如果执行过需要重新执行可以添加 --overwrite-conf 参数重新分发配置文件
#--no-adjust-repos，在不添加这个参数的时候，每次执行命令都会重新安装包，添加后会进行检查，已经安装过的不再安装
# 如果是ubuntu系统，这里需要多安装python2.7包，并做软连接
# apt install python2.7 -y
# ln -sv /usr/bin/python2.7 /usr/bin/python2

#添加OSD之前安装基础环境[node节点安装]：
ceph-deploy install --no-adjust-repos --nogpgcheck ceph-node01 ceph-node02
#如果出现故障：
# 故障机器执行以下命令，再次回到部署机
yum remove ceph-release-1-1.el7.noarch.rpm
yum instlal https://mirrors.163.com/ceph/rpm-octopus/el7/noarch/ceph-release-1-1.el7.noarch.rpm
yum clean all
yum makecache
yum install ceph-release
yum install ceph ceph-radosgw
#注意： 如果出现安装ceph-adosgw报错，可以这样解决
#原因可能因为你装过阿里云这个源
https://mirrors.aliyun.com/ceph/rpm-octopus/el7/noarch/ceph-release-1-1.el7.noarch.rpm
#导致错误问题：
ceph-osd = 2:13.2.8-0.el7
Available: 2:ceph-osd-13.2.9-0.el7.x86_64 (Ceph)
ceph-osd = 2:13.2.9-0.el7
Available: 2:ceph-osd-13.2.10-0.el7.x86_64 (Ceph)
ceph-osd = 2:13.2.10-0.el7
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
#这个错误是因为源应该配置为 nautilus 版，但是我配置成了其他版本
# 为了避免这个问题出现，建议直接安装163得源
yum instlal https://mirrors.163.com/ceph/rpm-octopus/el7/noarch/ceph-release-1-1.el7.noarch.rpm
#安装失败的node01 node02 修改为163的ceph.repo源 [安装之前装的源是163的 就不会出现上面问题]：
修改 rpm-minic 改为： nautilus
vim ceph.repo
%s#rpm-mimic#rpm-nautilus#g
sed替换：
sed -i ‘s#rpm-mimic#rpm-nautilus#g‘ /etc/yum.repos.d/ceph.repo
#改好的ceph.repo配置：
cat /etc/yum.repos.d/ceph.repo:

export CEPH_DEPLOY_GPG_URL=http://mirrors.163.com/ceph/keys/release.asc
# 指定版本安装：
--release=14.2.22 --release=nautilus
# 这个问题出现在centos中，默认安装的版本不稳定，导致后续无法安装，所以这里就让他安装稳定的 14.2.22版本
#
然后再次执行就可以正常安装了：
ceph-deploy install ceph-node01 ceph-node02
#指定版本：
ceph-deploy install --release=14.2.22 ceph-node01 ceph-node02
#所以还是建议一开始就装 163 源 这样就不会出现这样的问题了

# ceph-node01 添加完了第一块，现在添加第二块：
[ceph@ceph-mon01 ceph-cluster]$ ceph-deploy osd create ceph-node01 --data /dev/sdc
#输出和上面一样 就不写了
#node02 的第二块也加上去
[ceph@ceph-mon01 ceph-cluster]$ ceph-deploy osd create ceph-node02 --data /dev/sdc
#添加磁盘例子：ceph-deploy osd create ceph-node01 --data /dev/sda

这里的ID是物理磁盘的ID号，很有用。它可以区分物理磁盘

1.查看osd
ceph osd tree
2. 查看osd服务
#这个服务 添加了几块磁盘就会有几个osd，1代表序号
systemctl status ceph-osd@1
3. 检查osd状态
[root@ceph-node01 ~]# ceph osd tree
ID CLASS WEIGHT TYPE NAME STATUS REWEIGHT PRI-AFF
-1 0.39075 root default
-3 0.19537 host ceph-node01
0 hdd 0.09769 osd.0 up 1.00000 1.00000
1 hdd 0.09769 osd.1 up 1.00000 1.00000
-5 0.19537 host ceph-node02
2 hdd 0.09769 osd.2 up 1.00000 1.00000
3 hdd 0.09769 osd.3 up 1.00000 1.00000
3. 停止单个osd服务
systemctl stop ceph-osd@1
4. 移除单个 osd
ceph osd crush rm osd.3
5. 删除osd的密钥key
ceph auth del osd.3
6. 删除osd:
ceph osd rm osd.3
7. ceph.conf配置文件删除该主机
安装dashboard
#部署dashboard
yum install -y ceph-mgr-dashboard
#启用dashboard
ceph mgr module enable dashboard
#配置登录dashboard用户密码
echo ‘admin‘ >password
ceph dashboard ac-user-create admin administrator -i password
#查看解析的域名地址：
[root@ceph-mgr01 ~]# ceph mgr services
