修改时区
cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
安装NTP
yum -y install ntp
systemctl enable ntpd
systemctl start ntpd
ntpstat
rpm -Uvh https://dl.fedoraproject.org/pub/epel/7Server/x86_64/Packages/e/epel-release-7-11.noarch.rpm
这个包在写这个博文的时候是可用的,过段时间可能会失效,如果失效了请大家按照这个路径去找,release的包,不一定是7-11的,不过没关系,安装了这个包之后,后面的安装一般没有问题。
添加之前请先确认mirrors.163.com/ceph/rpm-hammer/el7/x86_64/是否存在,如果不存在,那么需要修改一下网址
vi ceph.repo
[ceph]
name=Ceph noarch packages
baseurl=http://mirrors.163.com/ceph/rpm-hammer/el7/x86_64/
enabled=1
gpgcheck=1
type=rpm-md
gpgkey=http://mirrors.163.com/ceph/keys/release.asc
yum -y update && yum -y install --release hammer ceph ceph-deploy
yum -y update && yum -y install --release hammer ceph
生成密钥对(一路回车即可)
ssh-keygen
将公钥拷贝到其余节点
ssh-copy-id root@node1
ssh-copy-id root@node2
ssh-copy-id root@node3
测试,ssh到各个节点,看是否需要输入密码
验证安装效果
命令行输入ceph按Tab键不齐,如果出现其余命令,则说明已经安装完成啦!
[root@localhost /]# ceph
ceph ceph-dencoder ceph-mon
ceph-authtool ceph-deploy ceph-objectstore-tool
ceph-brag ceph-disk ceph-osd
