centos7.1怎么手动安装ceph
在CentOS 7.1上手动安装Ceph,需要按照以下步骤:
1. 安装Ceph的必备软件包。首先,需要安装Ceph的必备软件包,包括libedit-devel、libuuid-devel、openssl-devel、popt-devel、libudev-devel、python-devel、libaio-devel、xfsprogs-devel、libxml2-devel、librados2、librbd1、librgw2、libcephfs1、radosgw和ceph-common。这些软件包可以从CentOS 7.1的官方软件源安装,使用yum install命令安装:
yum install libedit-devel libuuid-devel openssl-devel popt-devel libudev-devel python-devel libaio-devel xfsprogs-devel libxml2-devel librados2 librbd1 librgw2 libcephfs1 radosgw ceph-common
2. 安装Ceph。安装Ceph的最简单方法是从源代码构建,或者从源代码构建Ceph的RPM包。要从源代码构建Ceph,需要安装git,并从Ceph的GitHub存储库克隆Ceph的源代码:
yum install git git clone https://github.com/ceph/ceph
然后,进入Ceph的源代码目录,构建Ceph:
cd ceph ./autogen.sh ./configure make make install
3. 配置Ceph。安装Ceph后,需要创建一个Ceph配置文件,即/etc/ceph/ceph.conf。Ceph配置文件需要根据Ceph集群的需求进行调整,以配置Ceph集群的服务,例如存储池、对象和文件系统等。配置文件的示例如下:
[global] auth cluster required = cephx auth service required = cephx auth client required = cephx keyring = /etc/ceph/ceph.client.admin.keyring mon_initial_members = ceph1, ceph2, ceph3 mon_host = 10.0.0.1, 10.0.0.2, 10.0.0.3 public_network = 10.0.0.0/24 cluster_network = 10.0.1.0/24 mon_port = 6789 [osd] osd journal size = 1024 osd pool default size = 2 osd pool default min size = 1 osd pool default pg num = 8 osd pool default pgp num = 8
4. 创建Ceph Keyring。Ceph使用CephX认证机制来验证各个Ceph节点之间的安全性。要创建Ceph Keyring,需要使用ceph-authtool命令,并使用--gen-key参数:
ceph-authtool --gen-key --name=client.admin /etc/ceph/ceph.client.admin.keyring
5. 启动Ceph服务。要启动Ceph服务,需要使用systemctl命令,并使用start参数:
systemctl start ceph.target systemctl start ceph-mon@ceph1 systemctl start ceph-mon@ceph2 systemctl start ceph-mon@ceph3 systemctl start ceph-osd@0 systemctl start ceph-osd@1 systemctl start ceph-osd@2
6. 检查Ceph集群的状态。要检查Ceph集群的状态,需要使用ceph命令,并使用status参数:
ceph -s
如果Ceph集群处于正常状态,则会显示Ceph集群的状态,包括存储池、对象、文件系统等。
