报错和修复

failure: repodata/repomd.xml from ftp-yum-repo: [Errno 256] No more mirrors to try.
ftp://192.168.164.16/localrepo/ansible/repodata/repomd.xml: [Errno 14] FTP Error 550 - Server denied you to change to the given directory

报错原因是错误指定rpm包的位置 ( /var/ftp/localrepo )

正确指定rpm的位置是 /var/ftp/localrepo/ansible

正确更新yum仓库的命令是 createrepo --update /var/ftp/localrepo/ansible

 One of the configured repositories failed (ansible),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

     1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Run the command with the repository temporarily disabled
            yum --disablerepo=ftp-yum-repo ...

     4. Disable the repository permanently, so yum won't use it by default. Yum
        will then just ignore the repository until you permanently enable it
        again or use --enablerepo for temporary usage:

            yum-config-manager --disable ftp-yum-repo
        or
            subscription-manager repos --disable=ftp-yum-repo

     5. Configure the failing repository to be skipped, if it is unavailable.
        Note that yum will try to contact the repo. when it runs most commands,
        so will have to try and fail each time (and thus. yum will be be much
        slower). If it is a very temporary problem though, this is often a nice
        compromise:

            yum-config-manager --save --setopt=ftp-yum-repo.skip_if_unavailable=true

failure: repodata/repomd.xml from ftp-yum-repo: [Errno 256] No more mirrors to try.
ftp://192.168.164.16/localrepo/ansible/repodata/repomd.xml: [Errno 14] FTP Error 550 - Server denied you to change to the given directory

mkdir -p ~/ansible

# 配置ssh服务
ssh-keygen -t rsa -b 2048 -N '' -f /root/.ssh/id_rsa

# 更新权限
chmod 0400 /root/.ssh/id_rsa

# 循环传输公钥
for ip in 192.168.164.{10..17} 192.168.164.{51..56}
do
  ssh-copy-id -f -o stricthostkeychecking=no -i /root/.ssh/id_rsa.pub root@${ip}
done
