CentOS7.7 ceph mimic版本安装部署&运维中发现的问题汇总

1.安装问题

1.1连接超时

[node1][DEBUG ] Downloading packages:
[node1][WARNIN] No data was received after 300 seconds, disconnecting...

解决方案：

1.更换源重试

网易云：

export CEPH_DEPLOY_REPO_URL=http://mirrors.163.com/ceph/rpm-mimic/el7
export CEPH_DEPLOY_GPG_URL=http://mirrors.163.com/ceph/keys/release.asc

阿里云：

export CEPH_DEPLOY_REPO_URL=https://mirrors.aliyun.com/ceph/rpm-mimic/el7/
export CEPH_DEPLOY_GPG_URL=https://mirrors.aliyun.com/ceph/keys/release.asc

2.去相应的虚拟机上把超时出错的包重下一遍

例如此处超时的依赖为epel-release，则去相应节点上

yum remove epel-release

3.在每个节点分别安装

最后这个方法最好用，比较普适

yum -y install ceph

注意！

上述解决方案应在禁用fastestmirror插件的前提下进行
