一.ceph-dashboard基于http实战

1.ceph dashboard概述

Ceph Dashboard是一个内置的基于web的Ceph管理和监控应用程序，用于管理集群的各个方面和对象。

它被实现为一个Ceph管理器(mgr)守护程序模块。

    https://docs.ceph.com/en/nautilus/mgr/dashboard/#overview

2.ceph集群所有节点安装ceph-mgr-dashboard组件

[root@ceph141 ~]# yum -y install ceph-mgr-dashboard jq

[root@ceph142 ~]# yum -y install ceph-mgr-dashboard jq

[root@ceph143 ~]# yum -y install ceph-mgr-dashboard jq

3.启用dashboard功能

    1 查看默认启用的模块
[root@ceph141 ~]# ceph mgr module ls | jq .enabled_modules
[
  "iostat",
  "restful"
]
[root@ceph141 ~]#


    2 启用dashboard功能
[root@ceph141 ~]# ceph mgr module enable dashboard


    3 再次查看默认启用的模块，发现启用了dashboard模块！
[root@ceph141 ~]# ceph mgr module ls | jq .enabled_modules
[
  "dashboard",
  "iostat",
  "restful"
]
[root@ceph141 ~]#

4.修改mgr的默认配置

    1 不使用自签证书功能
[root@ceph141 ~]# ceph config set mgr mgr/dashboard/ssl false


    2 配置dashboard的监听地址
[root@ceph141 ~]# ceph config set mgr mgr/dashboard/server_addr 0.0.0.0


    3 配置dashboard的监听端口，默认是8080端口，修改端口不要小于1024，对于普通用户ceph没有权限监听小于1024的端口哟~
[root@ceph141 ~]# ceph config set mgr mgr/dashboard/server_port 1025

5.创建dashboard用于登录的用户认证信息

[root@ceph141 ~]# echo yinzhengjie > password.txt
[root@ceph141 ~]# 
[root@ceph141 ~]# cat password.txt 
yinzhengjie
[root@ceph141 ~]# 
[root@ceph141 ~]# ceph dashboard ac-user-create admin -i password.txt  administrator
{"username": "admin", "lastUpdate": 1706867058, "name": null, "roles": ["administrator"], "password": "$2b$12$Ce7eGVGOd9pgqfHp/THWxuZBrF4EVpgkWiWdP5h7iBUq98d9g1EoW", "email": null}
[root@ceph141 ~]#

6.重启ceph-mgr使得配置生效

[root@ceph142 ~]# ceph mgr services
{
    "dashboard": "http://ceph142:8080/"
}
[root@ceph142 ~]# 
[root@ceph142 ~]# systemctl restart ceph-mgr@ceph142.service  # 重启服务可能需要等待一会才能生效，一般也就5s~10s左右
[root@ceph142 ~]# 
[root@ceph142 ~]# ceph mgr services
{
    "dashboard": "http://ceph142:1025/"
}
[root@ceph142 ~]#

7.测试访问

http://ceph142:1025/#/dashboard

二.ceph-dashboard基于https实战

1.生成证书

[root@ceph141 ~]# ceph dashboard create-self-signed-cert
Self-signed certificate created
[root@ceph141 ~]#

2.启用SSL

[root@ceph141 ~]# ceph config set mgr mgr/dashboard/ssl true

3.重启mgr服务使得配置生效

[root@ceph142 ~]# ceph mgr services
{
    "dashboard": "http://ceph142:1025/"
}
[root@ceph142 ~]# 
[root@ceph142 ~]# systemctl restart ceph-mgr@ceph142.service  # 注意你自己集群的ceph对应的dashboard所在节点，修改为相应的主机名称。
[root@ceph142 ~]# 
[root@ceph142 ~]# ceph mgr services
{
    "dashboard": "https://ceph142:8443/"
}
[root@ceph142 ~]#

4.基于https端口进行访问

https://ceph142:8443/
