screen 命令使用及示例
|
||
============================================================
|
||
|
||
|
||
|
||
`screen` 是一个非常有用的命令，提供从单个 SSH 会话中使用多个 shell 窗口（会话）的能力。当会话被分离或网络中断时，screen 会话中启动的进程仍将运行，你可以随时重新连接到 screen 会话。如果你想运行一个持久的进程或者从多个位置连接到 shell 会话，这也很方便。
|
||
|
||
在本文中，我们将展示在 Linux 上安装和使用 `screen` 的基本知识。
|
||
|
||
### 如何安装 screen
|
||
|
||
`screen` 在一些流行的发行版上已经预安装了。你可以使用下面的命令检查是否已经在你的服务器上安装了。
|
||
|
||
```
|
||
screen -v
|
||
Screen version 4.00.03 (FAU)
|
||
```
|
||
|
||
如果在 Linux 中还没有 `screen`，你可以使用系统提供的包管理器很简单地安装它。
|
||
|
||
**CentOS/RedHat/Fedora**
|
||
|
||
```
|
||
yum -y install screen
|
||
```
|
||
|
||
**Ubuntu/Debian**
|
||
|
||
```
|
||
apt-get -y install screen
|
||
```
|
||
|
||
### 如何启动一个 screen 会话
|
||
|
||
你可以在命令行中输入 `screen` 来启动它，接着会有一个看上去和命令行提示符一样的 `screen` 会话启动。
|
||
|
||
```
|
||
screen
|
||
```
|
||
|
||
使用描述性名称启动屏幕会话是一个很好的做法，这样你可以轻松地记住会话中正在运行的进程。要使用会话名称创建新会话，请运行以下命令：
|
||
|
||
```
|
||
screen -S name
|
||
```
|
||
|
||
将 “name” 替换为对你会话有意义的名字。
|
||
|
||
### 从 screen 会话中分离
|
||
|
||
要从当前的 screen 会话中分离，你可以按下 `Ctrl-A` 和 `d`。所有的 screen 会话仍将是活跃的，你之后可以随时重新连接。
|
||
|
||
### 重新连接到 screen 会话
|
||
|
||
如果你从一个会话分离，或者由于某些原因你的连接被中断了，你可以使用下面的命令重新连接：
|
||
|
||
```
|
||
screen -r
|
||
```
|
||
|
||
如果你有多个 screen 会话，你可以用 `ls` 参数列出它们。
|
||
|
||
```
|
||
screen -ls
|
||
|
||
There are screens on:
|
||
7880.session (Detached)
|
||
7934.session2 (Detached)
|
||
7907.session1 (Detached)
|
||
3 Sockets in /var/run/screen/S-root.
|
||
```
|
||
|
||
在我们的例子中，我们有三个活跃的 screen 会话。因此，如果你想要还原 “session2” 会话，你可以执行：
|
||
|
||
```
|
||
screen -r 7934
|
||
```
|
||
|
||
或者使用 screen 名称。
|
||
|
||
```
|
||
screen -r -S session2
|
||
```
|
||
|
||
### 中止 screen 会话
|
||
|
||
有几种方法来中止 screen 会话。你可以按下 `Ctrl+d`，或者在命令行中使用 `exit` 命令。
|
||
|
||
要查看 `screen` 命令所有有用的功能，你可以查看 `screen` 的 man 手册。
|
||
|
||
```
|
||
man screen
|
||
|
||
NAME
|
||

||
