Detail

proxy_env

在某些受到“互联网封锁”的地区,有些软件的下载会受到影响。

例如,从中国大陆访问PostgreSQL的官方源,下载速度可能只有几KB每秒。但如果使用了合适的HTTP代理,则可以达到几MB每秒。

因此,如果您有代理服务器,请通过proxy_env进行配置,样例如下:

proxy_env: # global proxy env when downloading packages
  http_proxy: 'http://username:password@proxy.address.com'
  https_proxy: 'http://username:password@proxy.address.com'
  all_proxy: 'http://username:password@proxy.address.com'
  no_proxy: "localhost,127.0.0.1,10.0.0.0/8,192.168.0.0/16,*.pigsty,*.aliyun.com"

ansible_host

如果您的环境使用了跳板机,或者进行了某些定制化修改,无法通过简单的ssh <ip>方式访问,那么可以考虑使用Ansible的连接参数。

Ansible中关于SSH连接的参数

  • ansible_host

    The name of the host to connect to, if different from the alias you wish to give to it.

  • ansible_port

    The ssh port number, if not 22

  • ansible_user

    The default ssh user name to use.

  • ansible_ssh_pass

    The ssh password to use (never store this variable in plain text; always use a vault. See Variables and Vaults)

  • ansible_ssh_private_key_file

    Private key file used by ssh. Useful if using multiple keys and you don’t want to use SSH agent.

  • ansible_ssh_common_args

    This setting is always appended to the default command line for sftp, scp, and ssh. Useful to configure a ProxyCommand for a certain host (or group).

  • ansible_sftp_extra_args

    This setting is always appended to the default sftp command line.

  • ansible_scp_extra_args

    This setting is always appended to the default scp command line.

  • ansible_ssh_extra_args

    This setting is always appended to the default ssh command line.

  • ansible_ssh_pipelining

    Determines whether or not to use SSH pipelining. This can override the pipelining setting in ansible.cfg.

最简单的用法是将ssh alias配置为ansible_host,只要您可以通过ssh <name>的方式访问目标机器,那么将ansible_host配置为<name>即可。注意这些变量都是实例级别的变量。
