CentOS7部署ceph完整步骤

温馨提示:如在执行过程中遇到问题,请仔细检查执行命令的用户和所在目录。

1.环境准备

1.1系统配置说明

ip 安装服务 主机名 内核版本 备注
192.168.5.181 ceph、ceph-deploy admin-node CentOS Linux release 7.9.2009 (Core) 管理节点

192.168.5.182

ceph、mon、osd、rgw node1 CentOS Linux release 7.9.2009 (Core) osd、rgw节点
192.168.5.183 ceph、mon、osd node2 CentOS Linux release 7.9.2009 (Core) osd
192.168.5.184 ceph、mon、osd node3 CentOS Linux release 7.9.2009 (Core) osd

 

 

 

 

 

 

 

 

1.2关闭selinux和防火墙(所有节点)

#关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
#关闭selinux
setenforce 0
sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config

1.2设置时间同步(所有节点)

# yum 安装 ntp
yum install ntp ntpdate ntp-doc
# 校对系统时钟
ntpdate 0.cn.pool.ntp.org

1.3修改主机名和hosts文件(所有节点)

#192.168.5.181上操作
hostnamectl set-hostname admin-node
#192.168.5.182上操作
hostnamectl set-hostname node1
#192.168.5.183上操作
hostnamectl set-hostname node2
#192.168.5.184上操作
hostnamectl set-hostname node3
#所有节点上操作
vi /etc/hosts
#将以下内容增加到/etc/hosts中
192.168.5.181  admin-node
192.168.5.182  node1
192.168.5.183  node2
192.168.5.184  node3

1.4创建 Ceph 部署用户并设置其远程登录密码(所有节点)

# 创建 ceph 特定用户
useradd -d /home/cephd -m cephd
echo cephd | passwd cephd --stdin
# 添加 sudo 权限
echo "cephd ALL = (root) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/cephd
chmod 0440 /etc/sudoers.d/cephd
# node1、node2、node3上操作,设置cephd用户的远程登录密码,记住此密码,后面配置免密登录会用到
passwd cephd

1.5配置免密登录(admin-node节点)

# 切换到cephd用户
su cephd
# 生成ssh密钥,一路回车即可
ssh-keygen
# 将公钥复制到 node1 节点,输入cephd的用户密码即可
ssh-copy-id node1
# 将公钥复制到 node2 节点,输入cephd的用户密码即可
ssh-copy-id node2
# 将公钥复制到 node3 节点,输入cephd的用户密码即可
ssh-copy-id node3

2.Ceph集群搭建(ceph version 10.2.11)

2.1安装ceph-deploy(admin-node节点)

 配置ceph安装源

# yum 配置其他依赖包
sudo yum install -y yum-utils && sudo yum-config-manager --add-repo https://dl.fedoraproject.org/pub/epel/7/x86_64/ && sudo yum install --nogpgcheck -y epel-release && sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7 && rm /etc/yum.repos.d/dl.fedoraproject.org*
# 添加 Ceph 源
sudo vi /etc/yum.repos.d/ceph.repo
[ceph]
name=ceph
baseurl=http://mirrors.aliyun.com/ceph/rpm-jewel/el7/x86_64/
gpgcheck=0
[ceph-noarch]
name=cephnoarch
baseurl=http://mirrors.aliyun.com/ceph/rpm-jewel/el7/noarch/
gpgcheck=0

 安装 ceph-deploy

sudo yum update && sudo yum install ceph-deploy

 

2.2修改 ceph-deploy 管理节点上的 ~/.ssh/config 文件,这样无需每次执行 ceph-deploy 都要指定 –username cephd(admin-node)

sudo vi ~/.ssh/config
Host admin-node
   Hostname admin-node
   User cephd
Host node1
   Hostname node1
   User cephd
Host node2
   Hostname node2
   User cephd
Host node3
   Hostname node3
   User cephd
sudo chmod 600 ~/.ssh/config

2.3清理配置(admin-node)

# 清理 Ceph 安装包
sudo ceph-deploy purge admin-node node1 node2 node3
# 清理 Ceph 配置文件
sudo ceph-deploy purgedata admin-node node1 node2 node3
sudo ceph-deploy forgetkeys

2.4创建集群 mon节点(admin-node)

# 创建执行目录
mkdir /home/cephd/ceph-cluster && cd  /home/cephd/ceph-cluster
# 创建集群 mon节点
sudo ceph-deploy new node1 node2 node3

2.5修改ceph.conf配置文件(admin-node)

vi ceph.conf
#增加以下内容
osd pool default size = 2 #增加默认副本数为 2
osd max object name len = 256 
osd max object namespace len = 64

2.6安装ceph(admin-node)

sudo ceph-deploy install admin-node node1 node2 node3

2.7初始化 monitor 节点并收集所有密钥(admin-node)

sudo ceph-deploy --overwrite-conf mon create-initial

2.8修改硬盘挂载目录权限(node1、node2、node3)

 前提:挂载存储硬盘,参考我的另一篇博客,这里假设将硬盘挂载到/data目录

chown -R ceph:ceph /data

2.9准备OSD(admin-node)

sudo ceph-deploy  --overwrite-conf osd prepare node1:/data node2:/data  node3:/data 

2.10激活OSD(admin-node)

#激活osd
sudo ceph-deploy osd activate node1:/data node2:/data node3:/data
#通过 ceph-deploy admin 将配置文件和 admin 密钥同步到各个节点
sudo ceph-deploy admin node1 node2 node3

2.11修改ceph.client.admin.keyring权限(node1、node2、node3)

sudo chmod +r /etc/ceph/ceph.client.admin.keyring

2.12查看ceph集群状态(node1、node2、node3)

ceph -s

 

 自此,恭喜你,集群已经部署完成,那么如何使用集群呢,请继续往下看!

3.Ceph RGW网关部署及使用说明(ceph version 10.2.11)

3.1RGW网关部署(admin-node)

sudo ceph-deploy rgw create node1

 

 

 网关创建后默认会监听7480端口,请保证7480端口未被占用,否则可能会创建失败。

3.2RGW创建一个test1用户(node1)

radosgw-admin user create --uid test1 --display_name test1

 

 

 打马赛克的地方就是test1用户连接ceph集群所需要的公私钥,现在已经可以使用test1用户通过S3 API连接ceph存储集群做数据上传操作了,连接端口为7480。

3.3RGW用户容量限制(node1)

#限制test1用户最大上传的对象个数为1024个,最大使用空间为1024B,即1KB
radosgw-admin quota set --quota-scope=user --uid=test1 --max-objects=1024 --max-size=1024B
#启用用户空间限制
radosgw-admin quota enable --quota-scope=user --uid=test1

3.4RGW bucket容量限制(node1)

#限制用户test1拥有的存储桶最大上传对象为1024个,最大空间为1024B
radosgw-admin quota set --uid=test1 --quota-scope=bucket --max-objects=1024 --max-size=1024B
#启用桶容量限制
radosgw-admin quota enable --quota-scope=bucket --uid=test1

4.Java连接Ceph RGW网关进行存储相关操作(ceph version 10.2.11)

4.1构建maven工程,并添加以下依赖

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk</artifactId>
    <version>1.9.6</version>
</dependency>

4.2编写S3Utils工具类

4.3使用S3Utils工具类进行相关操作即可

创建S3对象的endPoint为http://192.168.5.182:7480

公私钥是上面网关创建时生成的公私钥
