1.1 各版本规划如下表
到今目前为止各软件的支持情况 https://docs.ceph.com/docs/master/releases/general/
1.2 查看磁盘信息
# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT vda 253:0 0 50G 0 disk └─vda1 253:1 0 50G 0 part / vdb 253:16 0 20G 0 disk vdc 253:32 0 20G 0 disk vdd 253:48 0 20G 0 disk
2.1需要配置时间同步
# crontab -e */5 * * * * /usr/sbin/ntpdate time1.aliyun.com
或者使用
yum install ntpdate ntp -y ntpdate cn.ntp.org.cn systemctl restart ntpd && systemctl enable ntpd
2.2 关闭SELinux
sed -i "/^SELINUX/s/enforcing/disabled/" /etc/selinux/config setenforce 0
2.3 关闭firewalld
systemctl stop firewalld
systemctl disable firewalld
或者增加规则
firewall-cmd --zone=public --add-port=6789/tcp --permanent firewall-cmd --zone=public --add-port=6800-7100/tcp --permanent firewall-cmd --reload firewall-cmd --zone=public --list-all
2.4 增加本地hosts解析
# vim /etc/hosts 192.168.5.91 ceph01 192.168.5.92 ceph02 192.168.5.93 ceph03
2.5 配置sudo不需要tty，7.6应该不需要配置
sed -i ‘s/Default requiretty/#Default requiretty/‘ /etc/sudoers
2.6 创建ceph.repo配置ceph m版本的软件安装源
阿里其它版本软件源都在此位置找：http://mirrors.aliyun.com/ceph/
# vim /etc/yum.repos.d/ceph.repo [ceph] name=ceph baseurl=http://mirrors.aliyun.com/ceph/rpm-mimic/el7/x86_64/ gpgcheck=0 [ceph-noarch] name=cephnoarch baseurl=http://mirrors.aliyun.com/ceph/rpm-mimic/el7/noarch/ gpgcheck=0
2.7 创建cephadmin部署帐户
useradd cephadmin echo ‘cephadmin‘ | passwd --stdin cephadmin echo "cephadmin ALL = (root) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/cephadmin chmod 0440 /etc/sudoers.d/cephadmin
2.8 仅在ceph01 节点部署节点配置ssh免密钥登录
[root@ceph01 ~]# su - cephadmin [cephadmin@ceph01 ~]$ ssh-keygen [cephadmin@ceph01 ~]$ ssh-copy-id cephadmin@ceph01 [cephadmin@ceph01 ~]$ ssh-copy-id cephadmin@ceph02 [cephadmin@ceph01 ~]$ ssh-copy-id cephadmin@ceph03
3.1 在ceph01 节点安装ceph-deploy和python-pip软件
[cephadmin@ceph01 ~]$ sudo yum install -y ceph-deploy python-pip
3.2 在三个节点上安装ceph软件包
sudo yum install -y ceph ceph-radosgw
3.3 在ceph01上安装集群
[cephadmin@ceph01 ~]$ mkdir my-cluster [cephadmin@ceph01 ~]$ cd my-cluster/ [cephadmin@ceph01 my-cluster]$ ceph-deploy new ceph01 ceph02 ceph03 # 如果不指定自定义集群的名称默认为ceph，多个集群安装的时候可以进行指定。 ceph-deploy --cluster {cluster-name} new node1 node2 # 安装完成之后会生成配置文件 [cephadmin@ceph01 my-cluster]$ ls ceph.conf ceph-deploy-ceph.log ceph.mon.keyring
也可以将集群网络和内部网络互相隔离，在ceph.conf中增加两行配置。
[cephadmin@ceph01 my-cluster]$ cat ceph.conf [global] fsid = 4d02981a-cd20-4cc9-8390-7013da54b161 mon_initial_members = ceph01, ceph02, ceph03 mon_host = 192.168.5.91,192.168.5.92,192.168.5.93 auth_cluster_required = cephx auth_service_required = cephx auth_client_required = cephx # 如果是双网卡只设置一个网关，然后增加如下两行。若不分离网络请忽添加。 public network = 192.168.5.0/24 cluster network = 192.168.10.0/24
3.4 集群初始化monitor 监控组件
[cephadmin@ceph01 my-cluster]$ ceph-deploy mon create-initial
3.5 把配置信息拷贝到各个节点当中
[cephadmin@ceph01 my-cluster]$ ceph-deploy admin ceph01 ceph02 ceph03 # 在所有节点执行操作；为/etc/ceph 授予cephadmin的权限 sudo chown -R cephadmin.cephadmin /etc/ceph [cephadmin@ceph01 my-cluster]$ ceph -s # 查看集群状态
3.6 配置OSD，添加到上面的OSD当中，用来存储数据
在ceph01的my-cluster目录对3个节点进行操作：清空磁盘、创建磁盘、加 入集群中，如果不想整个磁盘做数据目录，但也不能使用目录，可以使用一个LVM分区。如果要在LVM卷上创建OSD，则参数--data 必须是volume_group/lv_name，而不是卷的块设备路径。
for dev in /dev/vdb /dev/vdc /dev/vdd do ceph-deploy disk zap ceph01 $dev ceph-deploy osd create ceph01 --data $dev ceph-deploy disk zap ceph02 $dev ceph-deploy osd create ceph02 --data $dev ceph-deploy disk zap ceph03 $dev ceph-deploy osd create ceph03 --data $dev done
一个OSD守护进程相当于一块物理磁盘
3.7 部署MGR，L版本以后需要安装mgr，它用来管理dashbord组件，必须要部署的。
[cephadmin@ceph01 my-cluster]$ ceph-deploy mgr create ceph01 ceph02 ceph03
4.1 打开dashboard模块
[cephadmin@ceph01 my-cluster]$ ceph mgr module ls
4.2 生成自签证书
[cephadmin@ceph01 my-cluster]$ ceph dashboard create-self-signed-cert
Self-signed certificate created
4.3 生成密钥对
[cephadmin@ceph01 mgr-dashboard]$ openssl req -new -nodes -x509 -subj "/O=IT/CN=ceph-mgr-dashboard" -days 3650 -keyout dashboard.key -out dashboard.crt -extensions v3_ca Generating a 2048 bit RSA private key ...................................+++ ...........+++ writing new private key to ‘dashboard.key‘ ----- [cephadmin@ceph01 mgr-dashboard]$ ls dashboard.crt dashboard.key
4.4 设置IP和端口，惹不设置默认为8443
[cephadmin@ceph01 my-cluster]$ ceph config set mgr mgr/dashboard/server_addr 192.168.5.91 [cephadmin@ceph01 my-cluster]$ ceph config set mgr mgr/dashboard/server_port 8080 [cephadmin@ceph01 my-cluster]$ ceph mgr services { "dashboard": "https://ceph01:8443/" }
4.5 重启dashboard
[cephadmin@ceph01 my-cluster]$ ceph mgr module disable dashboard [cephadmin@ceph01 my-cluster]$ ceph mgr module enable dashboard [cephadmin@ceph01 my-cluster]$ ceph mgr services { "dashboard": "https://192.168.5.91:8080/" }
4.6 设置登录帐号和密码
[cephadmin@ceph01 my-cluster]$ ceph dashboard set-login-credentials admin admin
4.7 可以直接访问
https://192.168.5.91:8080/
CentOS7.6 使用ceph-deploy部署mimic 13.2.8集群（一）
