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。
