由于搞不到红帽官网的软件包,只能使用CentOS的软件仓库,环境信息如下:

本文主要介绍服务端的安装配置,客户端的配置以及使用将在下一篇描述。

1、配置yum软件仓库

[root@ceph01 ~]# vi /etc/yum.repos.d/CentOS-Base.repo 
[Storage]
name=CentOS-$releasever - Storage
baseurl=https://mirrors.huaweicloud.com/centos/7.7.1908/storage/x86_64/ceph-nautilus/
gpgcheck=0
enabled=1
[root@ceph01 ~]# yum repolist

2、配置节点互信操作(ommit)

这里就是配置ssh互信操作,可以参考其他文章。

3、管理节点安装ceph-ansible

这里使用ceph01作为ansible的管理节点。

[root@ceph01 ~]# yum install ceph-ansible

4、创建yml配置文件

切换目录至/usr/share/ceph-ansible文件夹,分别创建all.yml、osds.yml以及site.yml。

[root@ceph01 ceph-ansible]# cd group_vars/
[root@ceph01 group_vars]# cp all.yml.sample all.yml
[root@ceph01 group_vars]# vi all.yml
dummy:
fetch_directory: ~/ceph-ansible-keys
ceph_origin: distro
ceph_repository: dummy
cephx: true
monitor_interface: eth0
journal_size: 5120
public_network: 192.168.120.0/24
dashboard_admin_user: admin
dashboard_admin_password: redhat
grafana_admin_user: admin
grafana_admin_password: redhat
[root@ceph01 group_vars]# cp osds.yml.sample osds.yml
[root@ceph01 group_vars]# vi osds.yml
dummy:
devices:
  - /dev/sdb
osd_auto_discovery: true
[root@ceph01 group_vars]# cd ../
[root@ceph01 ceph-ansible]# cp site.yml.sample site.yml

5、定义Ansible inventory文件

此文件就是/etc/ansible/hosts文件,加入以下内容:

[root@ceph01 ceph-ansible]# vi /etc/ansible/hosts
[mons]
ceph01
ceph02
ceph03

[osds]
ceph01
ceph02
ceph03
ceph04

[mgrs]
ceph01
ceph02

[grafana-server]
ceph03

6、检查各节点是否能正常通信

[root@ceph01 ceph-ansible]# ansible all -m ping
[WARNING]: log file at /root/ansible/ansible.log is not writeable and we cannot create it, aborting

[DEPRECATION WARNING]: The TRANSFORM_INVALID_GROUP_CHARS settings is set to allow bad characters in group names by 
default, this will change, but still be user configurable on deprecation. This feature will be removed in version 2.10. 
Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.
[WARNING]: Invalid characters were found in group names but not replaced, use -vvvv to see details

ceph03 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}
ceph04 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}
ceph02 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}
ceph01 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}

7、开始安装配置

在执行之前,一定要切换到all.yml和site.yml文件所在的目录,否则会报错的。

[root@ceph01 ~]# cd /usr/share/ceph-ansible
[root@ceph01 ceph-ansible]# ansible-playbook site.yml
......
