1. [ceph_deploy][ERROR ] RuntimeError: Failed to execute command: env DEBIAN_FRONTEND=noninteractive DEBIAN_PRIORITY=critical apt-get --assume-yes -q update

[admin-node][DEBUG ]   404  Not Found [IP: 158.69.68.124 80]
[admin-node][DEBUG ] Hit:6 http://cn.archive.ubuntu.com/ubuntu bionic-backports InRelease
[admin-node][DEBUG ] Reading package lists...
[admin-node][WARNIN] E: The repository 'http://download.ceph.com/debian-{ceph-stable-release} bionic Release' does not have a Release file.
[admin-node][ERROR ] RuntimeError: command returned non-zero exit status: 100
[ceph_deploy][ERROR ] RuntimeError: Failed to execute command: env DEBIAN_FRONTEND=noninteractive DEBIAN_PRIORITY=critical apt-get --assume-yes -q update

分析：这个[ERROR ]是因为[WARNIN] E: The repository 'http://download.ceph.com/debian-{ceph-stable-release} bionic Release' does not have a Release file.造成的。

解决方法：在admin-node上修改/etc/apt/sources.list.d/ceph.list内容如下：

deb http://download.ceph.com/debian-{ceph-stable-release}/ bionic main =>deb http://download.ceph.com/debian-luminous/ bionic main

[node1][WARNIN]  One of the configured repositories failed (Unknown),
[node1][WARNIN]  and yum doesn't have enough cached data to continue. At this point the only
[node1][WARNIN]  safe thing yum can do is fail. There are a few ways to work "fix" this:
...
[node1][WARNIN] Cannot find a valid baseurl for repo: extras/7/x86_64
[node1][ERROR ] RuntimeError: command returned non-zero exit status: 1
[ceph_deploy][ERROR ] RuntimeError: Failed to execute command: yum -y install ceph ceph-radosgw

解决方法：修改虚拟机的/etc/resolv.conf文件，nameserver为物理机的gateway(查询命令：ip route show)
# Generated by NetworkManager
nameserver 192.168.122.1 =>  10.38.50.1

route add default gw 10.38.50.1 dev eth0
