# Ceph基础环境准备
|
||
|
|
|
||
|
|
| 节点名称 | IP |
|
||
|
|
| :---------: | :----------: |
|
||
|
|
| ceph-node-1 | 192.168.1.10 |
|
||
|
|
| ceph-node-2 | 192.168.1.20 |
|
||
|
|
| ceph-node-3 | 192.168.1.30 |
|
||
|
|
|
||
|
|
1. 所有节点时间同步(必做)
|
||
|
|
|
||
|
|
[请查看此文章](https://gitee.com/offends/Linux/blob/main/Docs/NTP%E6%97%B6%E9%97%B4%E5%90%8C%E6%AD%A5.md)
|
||
|
|
|
||
|
|
2. 更改主机名
|
||
|
|
|
||
|
|
- ceph-node-1
|
||
|
|
|
||
|
|
```bash
|
||
|
|
hostnamectl set-hostname ceph-node-1 && bash
|
||
|
|
```
|
||
|
|
|
||
|
|
- ceph-node-2
|
||
|
|
|
||
|
|
```bash
|
||
|
|
hostnamectl set-hostname ceph-node-2 && bash
|
||
|
|
```
|
||
|
|
|
||
|
|
- ceph-node-3
|
||
|
|
|
||
|
|
```bash
|
||
|
|
hostnamectl set-hostname ceph-node-3 && bash
|
||
|
|
```
|
||
|
|
|
||
|
|
3. 配置 Hosts 文件
|
||
|
|
|
||
|
|
```bash
|
||
|
|
cat >> /etc/hosts <<EOF
|
||
|
|
192.168.1.10 ceph-node-1
|
||
|
|
192.168.1.20 ceph-node-2
|
||
|
|
192.168.1.30 ceph-node-3
|
||
|
|
EOF
|
||
|
|
```
|
||
|
|
|
||
|
|
4. 禁用 selinux
|
||
|
|
|
||
|
|
```bash
|
||
|
|
sudo setenforce 0
|
||
|
|
sudo sed -i 's/^SELINUX=enforcing$/SELINUX=disabled/' /etc/selinux/config
|
||
|
|
```
|
||
|
|
|
||
|
|
或如果启用了 SELinux, 请运行以下命令
|
||
|
|
|
||
|
|
```bash
|
||
|
|
mkdir {/etc/ceph,/var/lib/ceph}
|
||
|
|
chcon -Rt svirt_sandbox_file_t /etc/ceph
|
||
|
|
chcon -Rt svirt_sandbox_file_t /var/lib/ceph
|
||
|
|
```
|
||
|
|
|
||
|
|
5. 关闭防火墙
|
||
|
|
|
||
|
|
```bash
|
||
|
|
systemctl stop firewalld
|
||
|
|
systemctl disable firewalld
|
||
|
|
```
|
||
|
|
|
||
|
|
6. 销毁磁盘上的分区表(用于清理旧盘)
|
||
|

|
|
- 官方清理方法
|
||
|
|
|
||
|
|
```bash
|
||
|
|
docker run --rm --privileged=true \
|
||
|
|
-v /dev/:/dev/ \
|
||
|
|
-e OSD_DEVICE=/dev/sdb \
|
||
|
|
quay.io/ceph/daemon:latest zap_device
|
||
|
|
```
|
||
|
|
|
||
|
|
- [磁盘清理](https://gitee.com/offends/Linux/blob/main/%E5%AD%98%E5%82%A8/%E7%A3%81%E7%9B%98%E6%B8%85%E7%90%86.md)
|

|
|
- 下载脚本清理
|
||
|
|
|
||
|
|
```bash
|
||
|
|
wget https://gitee.com/offends/Kubernetes/raw/main/File/Shell/clean-disk-ceph.sh
|
||
|
|
```
|
||
|
|
|
||
|
|
> 通过修改 `DISK=""` 字段实现选择磁盘
|
||
|
|
|
||
|
|
7. 配置快捷命令
|
||
|
|
|
||
|
|
```bash
|
||
|
|
echo 'alias ceph="docker exec ceph-mon ceph"' >> /etc/profile
|
||
|
|
source /etc/profile
|
||
|
|
```
