简介:
本文使用docker来部署ceph, 基于CentOS 7 x64.
首先要安装docker, CentOS 7源已经包含了docker, 所以可以直接使用yum安装.
# yum install -y docker

配置docker 运行时的root目录(-g 参数).
[root@localhost ~]# lvs
  LV   VG       Attr       LSize   Pool Origin Data%  Move Log Cpy%Sync Convert
  lv01 vgdata01 -wi-ao---- 409.32g                                             
[root@localhost ~]# df -h
Filesystem                 Size  Used Avail Use% Mounted on
/dev/mapper/vgdata01-lv01  410G  474M  409G   1% /data01

[root@localhost ~]# mkdir /data01/docker

配置docker服务启动项, 与CentOS 6有所不同, 配置如下 : 
[root@localhost ~]# vi /etc/sysconfig/docker
# /etc/sysconfig/docker
# Modify these options if you want to change the way the docker daemon runs
OPTIONS="--selinux-enabled=false -g /data01/docker"

启动docker server
[root@localhost ~]# systemctl start docker
[root@localhost ~]# ip link show docker0
6: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN mode DEFAULT 
    link/ether 56:84:7a:fe:97:99 brd ff:ff:ff:ff:ff:ff
[root@localhost ~]# ip addr show docker0

规划环境 : 
ceph install in CentOS 7 x64 within docker - 1 - 德哥@Digoal - PostgreSQL research

IP分别为 : 

docker0 172.17.42.1/16
br0  172.18.42.1/16
br1  172.19.42.1/16

deploy 
v00 172.17.0.1/16
v01 172.18.0.1/16
v02 172.19.0.1/16

mon1 
v10 172.17.0.2/16
v11 172.18.0.2/16
v12 172.19.0.2/16

v51 172.18.0.6/16
v52 172.19.0.6/16

osd3
v60 172.17.0.7/16
v61 172.18.0.7/16
v62 172.19.0.7/16

osd4
v70 172.17.0.8/16
v71 172.18.0.8/16
v72 172.19.0.8/16

生产的部署, 网络建议参考, 将OSD的心跳, 复制, 对外和监控分成3张网来通讯. 
(至少应该2张网络)
网络配置建议使用pipework工具, 简化繁琐的配置过程(因本文配置过程较为繁琐).
参考 : 

创建几个卷目录 : 

[root@150 ~]# cd /data01/
[root@localhost data01]# mkdir deploy
[root@localhost data01]# mkdir mon1
[root@localhost data01]# mkdir mon2
[root@localhost data01]# mkdir mon3
[root@localhost data01]# mkdir osd1
[root@localhost data01]# mkdir osd2
[root@localhost data01]# mkdir osd3
[root@localhost data01]# mkdir osd4

为了能够访问外网, 需要配置宿主机的nat规则配置 : 
# iptables rules
# Enable NAT
iptables -t nat -A POSTROUTING -s 172.16.42.0/24 ! -d 172.16.42.0/24 -j MASQUERADE
# Accept incoming packets for existing connections
iptables -A FORWARD -o docker0 -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
# Accept all non-intercontainer outgoing packets
iptables -A FORWARD -i docker0 ! -o docker0 -j ACCEPT
# By default allow all outgoing traffic
iptables -A FORWARD -i docker0 -o docker0 -j ACCEPT

开启宿主机forward : 
[root@localhost ~]# vi /etc/sysctl.conf
net.ipv4.ip_forward=1
[root@localhost ~]# sysctl -p
net.ipv4.ip_forward = 1


使用前面制作的sshd 镜像, 启动几个container.
http://blog.163.com/digoal@126/blog/static/1638770402014102711413675/
为了自定义IP, 这里不使用docker来配置网络, 而是使用netns来配置网络.
启动container(包括所有节点)


docker run -d --net=none --dns=202.101.172.35 --name=deploy --hostname=deploy --privileged=true -v /data01/deploy:/data01 digoal/sshd
docker run -d --net=none --dns=202.101.172.35 --name=mon1 --hostname=mon1 --privileged=true -v /data01/mon1:/data01 digoal/sshd
docker run -d --net=none --dns=202.101.172.35 --name=mon2 --hostname=mon2 --privileged=true -v /data01/mon2:/data01 digoal/sshd

docker run -d --net=none --dns=202.101.172.35 --name=osd3 --hostname=osd3 --privileged=true -v /data01/osd3:/data01 digoal/sshd
docker run -d --net=none --dns=202.101.172.35 --name=osd4 --hostname=osd4 --privileged=true -v /data01/osd4:/data01 digoal/sshd

状态如下 : 
[root@localhost data01]# docker ps

/*-------------------------------------------------------------------
使用pipework来配置更方便, 需要自行添加路由. 所以最好使用--privileged=true启动容器. 
建议使用网桥, 不要使用 OVS, 因为加入OVS的接口peer消失后不会自动删除.
例如 : 
./pipework.sh docker0 -i eth0 deploy 172.17.0.1/16
./pipework.sh br0 -i eth1 deploy 172.18.0.1/16
./pipework.sh br1 -i eth2 deploy 172.19.0.1/16

ssh 172.17.0.1
ip route add default via 172.17.42.1 dev eth0

pipework使用详见 : 

获得这container的PID, 以此来配置网络.

[root@localhost data01]# docker inspect -f '{{.State.Pid}}' deploy
17299
[root@localhost data01]# docker inspect -f '{{.State.Pid}}' mon1
17325
[root@localhost data01]# docker inspect -f '{{.State.Pid}}' mon2
17351
[root@localhost data01]# docker inspect -f '{{.State.Pid}}' mon3
17377
[root@localhost data01]# docker inspect -f '{{.State.Pid}}' osd1
17403
[root@localhost data01]# docker inspect -f '{{.State.Pid}}' osd2
17429
[root@localhost data01]# docker inspect -f '{{.State.Pid}}' osd3
17456
[root@localhost data01]# docker inspect -f '{{.State.Pid}}' osd4
17485

添加peer接口 : 
ip link add v00 type veth peer name vp00
ip link add v10 type veth peer name vp10
ip link add v20 type veth peer name vp20
ip link add v30 type veth peer name vp30
ip link add v40 type veth peer name vp40
ip link add v50 type veth peer name vp50
ip link add v60 type veth peer name vp60
ip link add v70 type veth peer name vp70
ip link add v01 type veth peer name vp01
ip link add v11 type veth peer name vp11
ip link add v21 type veth peer name vp21
ip link add v31 type veth peer name vp31
ip link add v41 type veth peer name vp41
ip link add v51 type veth peer name vp51
ip link add v61 type veth peer name vp61
ip link add v71 type veth peer name vp71
ip link add v02 type veth peer name vp02
ip link add v12 type veth peer name vp12
ip link add v22 type veth peer name vp22
ip link add v32 type veth peer name vp32
ip link add v42 type veth peer name vp42
ip link add v52 type veth peer name vp52
ip link add v62 type veth peer name vp62
ip link add v72 type veth peer name vp72

配置container的netns : 
mkdir -p /var/run/netns
rm -rf /var/run/netns/17299
rm -rf /var/run/netns/17325
rm -rf /var/run/netns/17351
rm -rf /var/run/netns/17377
rm -rf /var/run/netns/17403
rm -rf /var/run/netns/17429
rm -rf /var/run/netns/17456
rm -rf /var/run/netns/17485
ln -s /proc/17299/ns/net /var/run/netns/17299
ln -s /proc/17325/ns/net /var/run/netns/17325
ln -s /proc/17351/ns/net /var/run/netns/17351
ln -s /proc/17377/ns/net /var/run/netns/17377
ln -s /proc/17403/ns/net /var/run/netns/17403
ln -s /proc/17429/ns/net /var/run/netns/17429
ln -s /proc/17456/ns/net /var/run/netns/17456
ln -s /proc/17485/ns/net /var/run/netns/17485

将peer链路的一个端口分别指派给4个container.
ip link set v00 netns 17299
ip link set v01 netns 17299
ip link set v02 netns 17299
ip link set v10 netns 17325
ip link set v11 netns 17325
ip link set v12 netns 17325
ip link set v20 netns 17351
ip link set v21 netns 17351
ip link set v22 netns 17351
ip link set v30 netns 17377
ip link set v31 netns 17377
ip link set v32 netns 17377
ip link set v40 netns 17403
ip link set v41 netns 17403
ip link set v42 netns 17403
ip link set v50 netns 17429
ip link set v51 netns 17429
ip link set v52 netns 17429
ip link set v60 netns 17456
ip link set v61 netns 17456
ip link set v62 netns 17456
ip link set v70 netns 17485
ip link set v71 netns 17485
ip link set v72 netns 17485

使用ip netns配置container的IP地址, 并添加默认路由, 指向docker server bridge : 
ip netns exec 17299 ip link set lo up
ip netns exec 17299 ip link set v00 up
ip netns exec 17299 ip link set v01 up
ip netns exec 17299 ip link set v02 up
ip netns exec 17299 ip addr add 172.17.0.1/16 dev v00

docker server 网桥地址
[root@localhost ~]# ip addr show docker0
6: docker0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP 
    link/ether 56:84:7a:fe:97:99 brd ff:ff:ff:ff:ff:ff
    inet 172.17.42.1/16 scope global docker0
       valid_lft forever preferred_lft forever
    inet6 fe80::5484:7aff:fefe:9799/64 scope link 
       valid_lft forever preferred_lft forever

添加2个网桥 : 
[root@localhost netns]# brctl addbr br0
[root@localhost netns]# brctl addbr br1
[root@localhost netns]# ip link set br0 up
[root@localhost netns]# ip link set br1 up
[root@localhost netns]# ip addr add 172.18.42.1/16 dev br0
[root@localhost netns]# ip addr add 172.19.42.1/16 dev br1

将peer链路的另一个端口加入docker server对应的网桥, br0以及br1, 并启动接口.

开始部署ceph : 
首先查看ceph安装环境的需求 : 
1. kernel版本, centos 7 的 内核版本3.10.x 符合需求.
2. 文件系统, centos 7 默认使用xfs文件系统, 符合要求.

(在所有的docker container中配置yum 仓库)
使用yum 安装, 首先要配置yum仓库, 参考如下 : 

REQUIREMENTS?

All Ceph deployments require Ceph packages (except for development). You should also add keys and recommended packages.

  • Keys: (Recommended) Whether you add repositories or download packages manually, you should download keys to verify the packages. If you do not get the keys, you may encounter security warnings. There are two keys: one for releases (common) and one for development (programmers and QA only). Choose the key that suits your needs. See Add Keys for details.
  • Ceph Extras: (Required) The Ceph Extras repository provides newer Ceph-enabled versions of packages which are already provided in your Linux distribution, but where newer versions are required to support Ceph. Examples of newer versions of available packages include QEMU for CentOS/RHEL distribution and iSCSI among others. If you intend to use any of the foregoing packages, you must add the Ceph Extras repository or download the packages manually. This repository also contains Ceph dependencies for those who intend to install Ceph manually. See Add Ceph Extras for details.
  • Ceph: (Required) All Ceph deployments require Ceph release packages, except for deployments that use development packages (development, QA, and bleeding edge deployments only). See Add Ceph for details.
  • Ceph Development: (Optional) If you are developing for Ceph, testing Ceph development builds, or if you want features from the bleeding edge of Ceph development, you may get Ceph development packages. See Add Ceph Development for details.
  • Apache/FastCGI: (Optional) If you are deploying a Ceph Object Storage service, you must install Apache and FastCGI. Ceph provides Apache and FastCGI builds that are identical to those available from Apache, but with 100-continue support. If you want to enable Ceph Object Gatewaydaemons with 100-continue support, you must retrieve Apache/FastCGI packages from the Ceph repository. See Add Apache/FastCGI for details.

If you intend to download packages manually, see Section Download Packages.


配置yum 仓库的步骤 : 
详细参考 : 
注: 使用rhel6或centos6的话, yum仓库配置文件中使用el6替换el7.

1. 添加 KEY

[root@150 ~]# rpm --import 'https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc'

2. 添加 ceph extras 源
[root@150 ~]# cd /etc/yum.repos.d/
[root@150 yum.repos.d]# uname -r
3.10.0-123.el7.x86_64
使用el7.
(目前ceph extras没有el的源, 只能添加同内核版本的fedora, 如centos7对应fedora19, 以后如果有了el源, 可以使用el7代替fedora19)

[root@150 yum.repos.d]# vi ceph-extras.repo
[ceph-extras]
name=Ceph Extras Packages
baseurl=http://ceph.com/packages/ceph-extras/rpm/fedora19/$basearch
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc

[ceph-extras-noarch]
name=Ceph Extras noarch
baseurl=http://ceph.com/packages/ceph-extras/rpm/fedora19/noarch
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc

[ceph-extras-source]
name=Ceph Extras Sources
baseurl=http://ceph.com/packages/ceph-extras/rpm/fedora19/SRPMS
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc

3. 添加 ceph源, 使用最新的stable release版本, giant, 如果以后出了其他版本, 可以使用其他版本名代替giant.
[root@db-172-16-3-221 yum.repos.d]# vi ceph.repo
[ceph]
name=Ceph packages for $basearch
baseurl=http://ceph.com/rpm-giant/el7/$basearch
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc

[ceph-noarch]
name=Ceph noarch packages
baseurl=http://ceph.com/rpm-giant/el7/noarch
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc

[ceph-source]
name=Ceph source packages
baseurl=http://ceph.com/rpm-giant/el7/SRPMS
enabled=0
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc

现有ceph的版本信息如下, 最新版本为G开头的Giant.

The major releases of Ceph include:

  • Giant: Giant is the most recent major release of Ceph. These packages are recommended for anyone deploying Ceph in a production environment. Critical bug fixes are backported and point releases are made as necessary.
  • Firefly: Firefly is the sixth major release of Ceph. These packages are recommended for anyone deploying Ceph in a production environment. Firefly is a long-term stable release, so critical bug fixes are backported and point releases are made as necessary.
  • Emperor: Emperor is the fifth major release of Ceph. These packages are are old and no longer supported, so we recommend that users upgrade to Firefly immediately.
  • Dumpling: Dumpling is the fourth major release of Ceph. These packages are older and not recommended for new users, but critical bug fixes are still backported as necessary. We encourage all Dumpling users to update to Firefly as soon as they are able to do so.
  • Argonaut, Bobtail, Cuttlefish: These are the first three releases of Ceph. These packages are old and no longer supported, so we recommend that users upgrade to a supported version.
4. 如果不使用对象存储服务, 可以不添加以下源.
[root@db-172-16-3-221 yum.repos.d]# vi ceph-apache.repo
[apache2-ceph-noarch]
name=Apache noarch packages for Ceph
baseurl=http://gitbuilder.ceph.com/apache2-rpm-fedora19-x86_64-basic/ref/master
enabled=1
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/autobuild.asc

[apache2-ceph-source]
name=Apache source packages for Ceph
baseurl=http://gitbuilder.ceph.com/apache2-rpm-fedora19-x86_64-basic/ref/master
enabled=0
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/autobuild.asc

enabled=0
priority=2
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/autobuild.asc

检查yum配置是否正确

* hard    nofile  131072
* soft    nproc   131072
* hard    nproc   131072
* soft    core    unlimited
* hard    core    unlimited
* soft    memlock 50000000
* hard    memlock 50000000
