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

@task
def 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\")
