Ceph安装记录.docxVIP

安装系统利用sanlogic-install-ceph-r1.iso镜像光盘进行安装，在选择安装节点类型时选择cephnode即可。配置节点基本信息hostnamehostname hostname安装4个节点，hostname分别为cephadmin cephnode1 cephnode2 cephnode3配置网络信息编辑/etc/sysconfig/network-scripts/ifcfg-eth0文件DEVICE=eth0TYPE=EthernetONBOOT=yesNM_CONTROLLED=yesBOOTPROTO=staticNETMASK=255.255.255.0IPADDR=192.168.1.170GATEWAY=192.168.1.1DNS1=218.2.135.1红色部分为需要修改的信息配置passwordless ssh-key创建key# ssh-keygenGenerating public/private rsa key pair.Enter file in which to save the key (/root/.ssh/id_rsa):Enter passphrase (empty for no passphrase):Enter same passphrase again:Your identification has been saved in /root/.ssh/id_rsa.Your public key has been saved in /root/.ssh/id_rsa.pub.The key fingerprint is:9e:55:1a:35:e5:2a:81:27:a5:d7:2c:81:a0:10:6c:82 root@cephadminThe keys randomart image is:+--[ RSA 2048]----+|..o. .. .o o.. ||E o. . .+ = o || o . + * + . || + * . || S + . || . o . || o || || |+-----------------+分发keyssh-copy-id root@cephnode1ssh-copy-id root@cephnode2ssh-copy-id root@cephnode3根据提示输入密码。关闭防火墙、selinuxiptables设置为清除所有规则：/etc/init.d/iptables stopchkconfig iptables offselinux编辑/etc/selinux/config# This file controls the state of SELinux on the system.# SELINUX= can take one of these three values:# enforcing - SELinux security policy is enforced.# permissive - SELinux prints warnings instead of enforcing.# disabled - No SELinux policy is loaded.SELINUX=disabled# SELINUXTYPE= can take one of these two values:# targeted - Targeted processes are protected,# mls - Multi Level Security protection.SELINUXTYPE=targeted修改红色标记信息动态停止selinuxsetenforce 0安装ceph内网安装1、ceph-deploy install --no-adjust-repos cephadmin cephnode1 cephnode2 cephnode3外网安装2、ceph-deploy install cephadmin cephnode1 cephnode2 cephnode3搭建集群1.在admin节点上创建集群目录mkdir /home/mycluster –p2.进入所创建的目录并创建监控节点cd /home/myclusterceph-deploy new cephnode1 cephnode2 cephnode3监控节点 必须创建奇数个编辑ceph.conf添加如下条目osd pool default
