使用 fabric 将你的公钥传到服务器

fabric 是部署好帮手
下面的代码实现 ssh-copy-id 的功能
批量上传你的 id_rsa.pub 到一组服务器

@taskdef copy_id(file="~/.ssh/id_rsa.pub"):    """fab push 公钥 ssh-copy-id"""    put(file, "/tmp/id.pub")    try:        run("if [ ! -d ~/.ssh ]; then mkdir -p ~/.ssh; fi")        run("if [ ! -f ~/.ssh/authorized_keys ]; then cp /tmp/id.pub ~/.ssh/authorized_keys && chmod 0600 ~/.ssh/authorized_keys; fi")        run("cat ~/.ssh/authorized_keys /tmp/id.pub | sort -u > /tmp/uniq.authorized_keys")        run("if [ `cat ~/.ssh/authorized_keys | wc -l` -lt `cat /tmp/uniq.authorized_keys | wc -l` ]; then cat /tmp/id.pub >> ~/.ssh/authorized_keys; fi")    finally:        run("rm -f /tmp/id.pub /tmp/uniq.authorized_keys")
