Ceph是一个分布式存储系统,它提供了高可靠性、可扩展性和容错性,在本文中,我们将介绍如何进行Ceph的分布式部署。
环境准备
1、硬件要求:至少需要3台服务器,每台服务器至少4GB内存和2个CPU核心。
2、操作系统:推荐使用CentOS 7或Ubuntu 16.04。
3、网络:确保所有服务器之间可以互相访问。
安装Ceph
1、在所有服务器上安装Ceph软件包:
sudo yum install -y epel-release sudo yum install -y ceph ceph-radosgw ceph-mon
2、配置Ceph:
在第一台服务器上创建/etc/ceph
目录并复制ceph.conf
模板文件:
sudo mkdir /etc/ceph sudo cp /etc/ceph/ceph.conf.sample /etc/ceph/ceph.conf
编辑/etc/ceph/ceph.conf
文件,设置以下内容:
[global] fsid = {UUID} 使用uuidgen生成一个唯一的UUID替换{UUID} mon_initial_members = {hostname1},{hostname2},{hostname3} 将{hostname1},{hostname2},{hostname3}替换为实际的主机名 mon_host = {hostname1} 将{hostname1}替换为实际的主机名 auth_cluster_required = cephx 启用cephx认证 auth_service_required = cephx 启用cephx认证服务 auth_client_required = cephx 启用cephx认证客户端 osd_pool_default_size = 2 OSD池默认大小为2,可以根据实际需求进行调整 osd_pool_default_min_size = 1 OSD池最小大小为1,可以根据实际需求进行调整 osd_pool_default_pg_num = 128 OSD池默认PG数量为128,可以根据实际需求进行调整
3、初始化Ceph集群:
在第一台服务器上运行以下命令:
sudo systemctl enable ceph-mon.target ceph.target osd.target rgw.target sudo systemctl start ceph-mon.target ceph.target osd.target rgw.target
部署RADOS Gateway(RGW)
1、在第二台服务器上安装Ceph RGW软件包:
