引言
為什么突然想起搭建一個基于IPv6的Ceph環境？純屬巧合，原本有一個項目需要搭建一個基于IPv6的文件系統，可惜Hadoop不支持（之前一直覺得Hadoop比較強大），幾經折騰，Ceph給了我希望，好了閑話少說，直接進入正題。
實驗環境
- Minimal鏡像?603M左右
- Everything鏡像?7.2G左右

網絡配置
參考之前的一篇文章CentOS7 設置靜態IPv6/IPv4地址完成網絡配置
修改主機名
| 1 2 3 4 5 | [root@localhost ~]# hostnamectl set-hostname ceph001 #ceph001即為你想要修改的名字 [root@localhost ~]# vim /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 2001:250:4402:2001:20c:29ff:fe25:8888 ceph001 #新增，前面IPv6地址即主機ceph001的靜態IPv6地址 |
修改yum源
由于某些原因，可能導致官方的yum在下載軟件時速度較慢，這里我們將yum源換為aliyun源
| 1 2 3 4 5 6 7 | [root@localhost ~]# yum clean all #清空yum源 [root@localhost ~]# rm -rf /etc/yum.repos.d/*.repo [root@localhost ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo #下載阿里base源 [root@localhost ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo #下載阿里epel源 [root@localhost ~]# sed -i '/aliyuncs/d' /etc/yum.repos.d/CentOS-Base.repo [root@localhost ~]# sed -i '/aliyuncs/d' /etc/yum.repos.d/epel.repo [root@localhost ~]# sed -i 's/$releasever/7.2.1511/g' /etc/yum.repos.d/CentOS-Base.repo |
?
添加ceph源
| 1 2 3 4 5 6 7 8 9 10 | [root@localhost ~]# vim /etc/yum.repos.d/ceph.repo [ceph] name=ceph baseurl=http://mirrors.aliyun.com/ceph/rpm-hammer/el7/x86_64/ #可以選擇需要安裝的版本 gpgcheck=0 [ceph-noarch] name=cephnoarch baseurl=http://mirrors.aliyun.com/ceph/rpm-hammer/el7/noarch/ #可以選擇需要安裝的版本 gpgcheck=0 [root@localhost ~]# yum makecache |
