• ceph安装


    一、部署准备:
    (1)所有ceph集群节点(包括客户端)设置静态域名解析;
    [root@zxw9 ~]# cat /etc/hosts
    127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
    ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
    192.168.126.6 zxw6
    192.168.126.7 zxw7
    192.168.126.8 zxw8
    192.168.126.9 zxw9


    (2)所有集群节点(包括客户端)创建cent用户,并设置密码,后执行如下命令:
    useradd cent && echo "123" | passwd --stdin cent

    echo -e 'Defaults:cent !requiretty cent ALL = (root) NOPASSWD:ALL' | tee /etc/sudoers.d/ceph

    chmod 440 /etc/sudoers.d/ceph
    (3)在部署节点切换为cent用户,设置无密钥登陆各节点包括客户端节点
    [root@zxw9 ~]# su - cent
    [cent@zxw9 ~]$
    [cent@zxw9 ~]$ ssh-keygen
    [cent@zxw9 ~]$ ssh-copy-id zxw6
    [cent@zxw9 ~]$ ssh-copy-id zxw7
    [cent@zxw9 ~]$ ssh-copy-id zxw8

    (4)在部署节点切换为cent用户,在cent用户家目录,设置如下文件:
    [cent@zxw9 ~]$ vim .ssh/config

    Host zxw9
    Hostname zxw9
    User cent
    Host zxw8
    Hostname zxw8
    User cent
    Host zxw7
    Hostname zxw7
    User cent
    Host zxw6
    Hostname zxw6
    User cent


    [cent@zxw9 ~]$ chmod 600 .ssh/config
    二、所有节点配置国内ceph源:
    vim ceph.repo

    [ceph]
    name = ceph1
    baseurl = https://mirrors.aliyun.com/centos/7.6.1810/storage/x86_64/ceph-jewel/
    enable = 1
    gpgcheck = 0

     

     


    (2)每个机器都下载到国内ceph源中https://mirrors.aliyun.com/centos/7.6.1810/storage/x86_64/ceph-jewel/下载如下所需rpm包。
    注意:红色框中为ceph-deploy的rpm,只需要在部署节点安装,下载需要到https://mirrors.aliyun.com/ceph/rpm-jewel/el7/noarch/中找到最新对应的ceph-deploy-xxxxx.noarch.rpm 下载
    1 ceph-10.2.11-0.el7.x86_64.rpm

    34 rbd-nbd-10.2.11-0.el7.x86_64.rpm
    (3)将下载好的rpm拷贝到所有节点,并安装。注意ceph-deploy-xxxxx.noarch.rpm 只有部署节点用到,其他节点不需要,部署节点也需要安装其余的rpm
     [root@zxw9 cephjrpm]# mv ceph-deploy-1.5.39-0.noarch.rpm /root
    [root@zxw9 ~]# yum localinstall ceph-deploy-1.5.39-0.noarch.rpm -y
    在部署节点(cent用户下执行):安装 ceph-deploy,在root用户下,进入下载好的rpm包目录,执行:

    yum localinstall -y ./*
    (或者sudo yum install ceph-deploy)
    创建ceph工作目录
    1 mkdir ceph &&  cd ceph
    注意:如遇到如下报错:

     

    处理办法1:
    可能不能安装成功,报如下问题:将python-distribute remove 再进行安装(或者 yum remove  python-setuptools -y)

     

    注意:如果不是安装上述方法添加的rpm,用的是网络源,每个节点必须yum install ceph ceph-radosgw -y
    处理办法2:
    安装依赖包:python-distribute

    因为目前的源用的是上面黄色标记openstack-ocata源,安装版本就成了python2-setuptools-22.0.5-1.el7.noarch,所以修改yum源后,只要保证安装 python-setuptools 版本是 0.9.8-7.el7 就可以通过了,如下把openstack-ocata 源移走或者删除:

    (6)在部署节点执行(cent用户下执行):所有节点安装ceph软件
    所有节点有如下软件包:
    1 root@rab116:13:59~/cephjrpm#ls
    2 ceph-10.2.11-0.el7.x86_64.rpm               ceph-resource-agents-10.2.11-0.el7.x86_64.rpm    librbd1-10.2.11-0.el7.x86_64.rpm

    所有节点安装上述软件包(包括客户端):
    1 yum localinstall ./* -y
     
    (7)在部署节点执行,所有节点安装ceph软件
    1 ceph-deploy install dlp node1 node2 node3
     
    (8)在部署节点初始化集群(cent用户下执行):
    1 ceph-deploy mon create-initial
     
    (9)在osd节点prepare Object Storage Daemon :
    1 mkdir /data && chown ceph.ceph /data


     
    (10)每个节点将第二块硬盘做分区,并格式化为xfs文件系统挂载到/data:
    1 root@con116:45:22/#fdisk /dev/vdb
    2   
    3 root@con116:45:22/#lsblk
    4 NAME        MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
    5 vda         252:0    0   40G  0 disk

    7 └─vda2      252:2    0 39.5G  0 part
    8  ├─cl-root 253:0    0 35.5G  0 lvm  /
    9  └─cl-swap 253:1    0    4G  0 lvm  [SWAP]
    10 vdb         252:16   0   10G  0 disk
    11 └─vdb1      252:17   0   10G  0 part
    12   
    13 root@rab116:54:35/#mkfs -t xfs /dev/vdb1
    14   
    15 root@rab116:54:50/#mount /dev/vdb1 /data/
    16   
    17 root@rab116:56:39/#lsblk
    18 NAME        MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
    19 vda         252:0    0   40G  0 disk
    20 ├─vda1      252:1    0  512M  0 part /boot
    21 └─vda2      252:2    0 39.5G  0 part

    23  └─cl-swap 253:1    0    4G  0 lvm  [SWAP]
    24 vdb         252:16   0   10G  0 disk
    25 └─vdb1      252:17   0   10G  0 part /data
     
    (11)在/data/下面创建osd挂载目录:
    1 mkdir /data/osd
    2 chown -R ceph.ceph /data/
    3 chmod 750 /data/osd/
    4 ln -s /data/osd /var/lib/ceph
    注意:准备前先将硬盘做文件系统 xfs,挂载到/var/lib/ceph/osd,并且注意属主和属主为ceph:
    列出节点磁盘:ceph-deploy disk list node1
    擦净节点磁盘:ceph-deploy disk zap node1:/dev/vdb1
     
    (12)准备Object Storage Daemon:
    1 ceph-deploy osd prepare node1:/var/lib/ceph/osd node2:/var/lib/ceph/osd node3:/var/lib/ceph/osd
     
    (13)激活Object Storage Daemon:
    1 ceph-deploy osd activate node1:/var/lib/ceph/osd node2:/var/lib/ceph/osd node3:/var/lib/ceph/osd
     
    (14)在部署节点transfer config files
    1 ceph-deploy admin dlp node1 node2 node3
    2 sudo chmod 644 /etc/ceph/ceph.client.admin.keyring
     
    (15)在ceph集群中任意节点检测:
    1 ceph -s

     

     


     
    三、客户端设置:
    (1)客户端也要有cent用户:
    1 useradd cent && echo "123" | passwd --stdin cent
    2 echo-e 'Defaults:cent !requiretty cent ALL = (root) NOPASSWD:ALL' | tee /etc/sudoers.d/ceph
    3 chmod440 /etc/sudoers.d/ceph
    在部署节点执行,安装ceph客户端及设置:
    1 ceph-deploy install controller
    2 ceph-deploy admin controller
     
    (2)客户端执行
    1 sudo chmod 644 /etc/ceph/ceph.client.admin.keyring
     
    (3)客户端执行,块设备rdb配置:
    1 创建rbd:rbd create disk01 --size 10G --image-feature layering    删除:rbd rm disk01
    2 列示rbd:rbd ls -l
    3 映射rbd的image map:sudo rbd map disk01      取消映射:sudo rbd unmap disk01
    4 显示map:rbd showmapped
    5 格式化disk01文件系统xfs:sudo mkfs.xfs /dev/rbd0
    6 挂载硬盘:sudo mount /dev/rbd0 /mnt
    7 验证是否挂着成功:df -hT
     
    (4)File System配置:
    在部署节点执行,选择一个node来创建MDS:
    1 ceph-deploy mds create node1
    以下操作在node1上执行:
    1 sudo chmod 644 /etc/ceph/ceph.client.admin.keyring
    在MDS节点node1上创建 cephfs_data 和  cephfs_metadata 的 pool
    1 ceph osd pool create cephfs_data 128
    2 ceph osd pool create cephfs_metadata 128
    开启pool:
    1 ceph fs new cephfs cephfs_metadata cephfs_data
    显示ceph fs:
    1 ceph fs ls
    2 ceph mds stat
     
    以下操作在客户端执行,安装ceph-fuse:
    1 yum -y install ceph-fuse
    获取admin key:
    1 sshcent@node1"sudo ceph-authtool -p /etc/ceph/ceph.client.admin.keyring" > admin.key
    2 chmod600 admin.key
    挂载ceph-fs:
    1 mount-t ceph node1:6789:/ /mnt -o name=admin,secretfile=admin.key
    2 df-hT
     
    停止ceph-mds服务:
    1 systemctl stop ceph-mds@node1
    2 ceph mds fail 0
    3 ceph fs rm cephfs --yes-i-really-mean-it
    4   
    5 ceph osd lspools
    6 显示结果:0 rbd,1 cephfs_data,2 cephfs_metadata,
    7   
    8 ceph osd pool rm cephfs_metadata cephfs_metadata --yes-i-really-really-mean-it
     
    四、删除环境:
    1 ceph-deploy purge dlp node1 node2 node3 controller
    2 ceph-deploy purgedata dlp node1 node2 node3 controller
    3 ceph-deploy forgetkeys
    4 rm -rf ceph*
