下面随小编一起去看看centos7.1手动安装ceph的方法吧！
1.准备环境
centos7.1主机一台
更新yum源
[root@cgsl ]# yum -y update
2.安装密钥 把密钥加入你系统的可信密钥列表内，以消除安全告警。
[root@cgsl ]# sudo rpm --import 'https://download.ceph.com/keys/release.asc'
3.获取RPM 二进制包 你需要在 /etc/yum.repos.d/ 目录下新增一个 Ceph 库：创建 ceph.repo 。 些 Ceph 包（如 EPEL ）必须优先于标准包，所以你必须确保设置了 priority=2 。
[root@cgsl ]# vim /etc/yum.repos.d/ceph.repo
[ceph]
name=Ceph packages for $basearch
baseurl=http://download.ceph.com/rpm-jewel/el7/$basearch
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://download.ceph.com/keys/release.asc
[ceph-noarch]
name=Ceph noarch packages
baseurl=http://download.ceph.com/rpm-jewel/el7/noarch
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://download.ceph.com/keys/release.asc
[ceph-source]
name=Ceph source packages
baseurl=http://download.ceph.com/rpm-jewel/el7/SRPMS
enabled=0
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://download.ceph.com/keys/release.asc
[apache2-ceph-noarch]
name=Apache noarch packages for Ceph
baseurl=http://gitbuilder.ceph.com/ceph-rpm-centos7-x86_64-basic/ref/master/SRPMS
#baseurl=http://gitbuilder.ceph.com/ceph-rpm-centos7-x86_64-basic/ref/master
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://download.ceph.com/keys/autobuild.asc
[apache2-ceph-source]
name=Apache source packages for Ceph
baseurl=http://gitbuilder.ceph.com/ceph-rpm-centos7-x86_64-basic/ref/master/SRPMS
#baseurl=http://gitbuilder.ceph.com/ceph-rpm-centos7-x86_64-basic/ref/master
enabled=0
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://download.ceph.com/keys/autobuild.asc
4.下载软件包 Ceph 依赖一些第三方库。执行下列命令添加 EPEL 库：
[root@cgsl ]# su -c 'rpm -Uvh http://download.ceph.com/rpm-jewel/el7/noarch/ceph-release-1-1.el7.noarch.rpm '
[root@cgsl ]# su -c 'rpm -Uvh https://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-9.noarch.rpm '
5.安装 yum-plugin-priorities 。
[root@cgsl ]# yum install yum-plugin-priorities
6.确认 /etc/yum/pluginconf.d/priorities.conf 文件存在。
[root@cgsl ]# vim /etc/yum/pluginconf.d/priorities.conf
7.安装依赖的的软件包：
[root@cgsl ]# yum install snappy leveldb gdisk python-argparse gperftools-libs
8.安装ceph
[root@cgsl ]# yum install ceph
