本地部署cpeh

docker run -itd --restart=always --name ceph-mon --network ceph-network --ip 172.20.0.10 \
-e CLUSTER=ceph -e WEIGHT=1.0 -e MON_IP=172.20.0.10 -e MON_NAME=ceph-mon -e CEPH_PUBLIC_NETWORK=172.20.0.0/16 \
-v /data/ceph/etc/ceph:/etc/ceph \
-v /data/ceph/var/lib/ceph/:/var/lib/ceph/ \
-v /data/ceph/var/log/ceph/:/var/log/ceph/ \
ceph/daemon mon

搭建osd节点
docker exec ceph-mon ceph auth get client.bootstrap-osd -o /var/lib/ceph/bootstrap-osd/ceph.keyring

修改配置文件以兼容etx4硬盘
sudo vi /etc/ceph/ceph.conf
在文件最后添加：

osd max object name len = 256
osd max object namespace len = 64

分别启动三个容器来模拟集群

docker run -itd --restart=always --privileged=true --name ceph-osd-0 --network ceph-network --ip 172.20.0.11 \
-e CLUSTER=ceph -e WEIGHT=1.0 -e MON_NAME=ceph-mon -e MON_IP=172.20.0.10 -e OSD_TYPE=directory \
-v /data/ceph/etc/ceph:/etc/ceph \
-v /data/ceph/var/lib/ceph/:/var/lib/ceph/ \
-v /data/ceph/var/lib/ceph/osd/0:/var/lib/ceph/osd \
-v /etc/localtime:/etc/localtime:ro \
ceph/daemon osd

docker run -itd --restart=always --privileged=true --name ceph-osd-1 --network ceph-network --ip 172.20.0.12 \
-e CLUSTER=ceph -e WEIGHT=1.0 -e MON_NAME=ceph-mon -e MON_IP=172.20.0.10 -e OSD_TYPE=directory \
-v /data/ceph/etc/ceph:/etc/ceph \
-v /data/ceph/var/lib/ceph/:/var/lib/ceph/ \
-v /data/ceph/var/lib/ceph/osd/1:/var/lib/ceph/osd \
-v /etc/localtime:/etc/localtime:ro \
ceph/daemon osd

docker run -itd --restart=always --privileged=true --name ceph-osd-2 --network ceph-network --ip 172.20.0.13 \
-e CLUSTER=ceph -e WEIGHT=1.0 -e MON_NAME=ceph-mon -e MON_IP=172.20.0.10 -e OSD_TYPE=directory \
-v /data/ceph/etc/ceph:/etc/ceph \
-v /data/ceph/var/lib/ceph/:/var/lib/ceph/ \
-v /data/ceph/var/lib/ceph/osd/2:/var/lib/ceph/osd \
-v /etc/localtime:/etc/localtime:ro \
ceph/daemon osd


5. 搭建mgr节点

docker run -itd --restart=always --privileged=true --name ceph-mgr --network ceph-network --ip 172.20.0.14 \
-e CLUSTER=ceph -p 7000:7000 --pid=container:ceph-mon \
-v /data/ceph/etc/ceph:/etc/ceph \
-v /data/ceph/var/lib/ceph/:/var/lib/ceph/ \
ceph/daemon mgr

开启管理界面
docker exec ceph-mgr ceph mgr module enable dashboard

docker exec ceph-mon ceph auth get client.bootstrap-rgw -o /var/lib/ceph/bootstrap-rgw/ceph.keyring

docker run -itd --restart=always --privileged=true --name ceph-rgw --network ceph-network --ip 172.20.0.15 \
-e CLUSTER=ceph -e RGW_NAME=ceph-rgw -p 7480:7480 \
-v /data/ceph/var/lib/ceph/:/var/lib/ceph/ \
-v /data/ceph/etc/ceph:/etc/ceph \
-v /etc/localtime:/etc/localtime:ro \
ceph/daemon rgw


3.6.1 开启dashboard功能

在master节点执行：
docker exec mgr ceph mgr module enable dashboard

设置用户名秘密
vi adminpw 里面设置密码admin123
//添加用户
ceph dashboard ac-user-create admin -i adminpw administrator
账号：admin 密码：admin123

3.6.4 配置外部访问端口
docker exec ceph-mgr ceph config set mgr mgr/dashboard/server_port 7000
3.6.5 配置外部访问IP
docker exec ceph-mgr ceph config set mgr mgr/dashboard/server_addr 0.0.0.0
3.6.6 重启Mgr DashBoard服务
docker restart ceph-mgr
3.6.7 查看Mgr DashBoard服务信息

docker exec ceph-mgr ceph mgr services
-------------------------------------------
{
   "dashboard": "http://10.00.00.00:7000"
}

//创建用户
radosgw-admin user create --uid=test01 --display-name=test01 --access-key=test01 --secret-key=test01 [email protected]

//查询pool
ceph osd lspools
//查询对象在那些osd上
osd map zrs myobject
//查询指定pool下的对象
ceph osd map zrs
//往指定pool打入数据压侧
rados -p zrs bench 20 write --no-cleanup

定时查看内存占用

#!/bin/bash
prog_name="chrome"
prog_mem=$(pidstat -r -u -h -C $prog_name |awk 'NR==4{print $12}')
time=$(date "+%Y/%m/%d/%H:%M:%S")
echo $time" "$prog_mem >>/data/tmp/prog_mem.log
