I constantly need to log into a remote server and do all kinds of work. I am using my Mac and every time I have to type in a long command to do that. 

ssh -i ~/key.pem ubuntu@255.255.255.255

I am wondering what would be the easiest way to log into the remote server without typing in the command everyday.

Handy apple apps are also welcome

Updated:

1> Thanks to Matt Bryant's answer. I successfully avoided typing in the whole username and host address by modifying ~/.ssh/config (doesn't exist as default) to 

Host <ShortName>
    User <UserName>
    HostName <HostIP>
    IdentityFile <KeyPath>

then I could just type this command to avoid typing in the full name of host and full path of the key:

ssh <ShortName>

2> Anyone knows how to store the pem key or avoid typing in the password if there is no pem key?

使用 ~/.ssh/config 文件。尝试添加以下内容：

Host server                                                                                                  
    User ubuntu
    HostName 255.255.255.255

这将允许您使用ssh -i ~/key.pem server. 如果您查看 ssh 配置，还有许多其他设置可以让您简化和增强您的 ssh 体验。

嗨 B MR W 是的，我将发布一个期望脚本，因为这出现了很多：

E2A 指令适用于 linux 在 mac 上有期望https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/expect.1.html 这可能意味着弄乱脚本来满足mac的标准期望我对此没有足够的了解，但原则上看过下面的过程应该可以工作

您对 ssh-copy-id 或脚本的哪一点感兴趣？

要使脚本运行，您需要

sudo-apt-get install expect or 
sudo yum install expect

一旦安装

这是一个典型的脚本：

#!/usr/bin/expect -f


set force_conservative 1  
if {$force_conservative} {
        set send_slow {1 .001}
        proc send {ignore arg} {
        sleep .001
                exp_send -s -- $arg
        }
}

;# Validate user input - make sure all fields required are given 
if {$argc >= 1} {
    ;# Setting  password
    set user "MYUSER";
    set supass "MYPASSWORD"

    set host [lindex $argv 0]
  #     set command1 [lindex $argv 2]

   set prompt "(:|#|%|>|\\\$|% |# |> |\\\$ )"
   set prompt1 "(>)"
   set timeout -1
   ;###############################################################

   ;#connect to specified host given by addstaff or globalstaff.
   spawn ssh $user@$host
   expect { 
        "*word:*" {}
        "*(yes/no)?*" {
                      send - "yes\r" 
                  expect "*word:" { }

                  } 
       }          

   send  - "$supass\r"
  expect eof exit -re $prompt

   send -  "sudo bash\r"
   expect   {
                 "*word:*" {
                         send  "$supass\r"
                         expect  eof exit -re $prompt
                 }
        "*" {  
              expect eof exit -re $prompt
        }

   }

    send  - "whoami\r"
        expect eof exit -re $prompt

    interact 

    ;#send  - "$command\r"
    ;#  expect eof exit -re $prompt

    ;#Logout of current ssh session
    ;#send  - "exit\r"
    ;#expect eof exit -re $prompt

    ;#send  - "exit\r"
    ;#expect eof exit -re $prompt


} else {
  send - "echo Sorry require user host command \n\n\r";
  exit
}

如果您注意到我已经注释掉了未发送的命令 - 它使用交互模式允许您在没有密码的情况下实际登录，在脚本顶部定义的用户密码......一旦登录，您就可以输入会按照正常的 ssh

这是我在本地运行它：

 whoami
myuser
./ssh-connection.exp localhost
spawn ssh myuser@localhost
myuser@localhost's password:

在脚本中它还执行 sudo bash 这就是为什么它将我重新连接到 localhost 并且我成为 root
