在本文中，我通過4個(gè)簡單步驟指導(dǎo)您完成在Linux(RHEL/CentOS 7/8)中安裝Screen命令。你遇到在Linux會話中運(yùn)行一些重要任務(wù)，但由于某些問題而突然中斷了會話，任務(wù)在兩個(gè)會話之間結(jié)束，

在Linux中安裝Screen命令(RHEL /CentOS )

步驟1：先決條件

a)你應(yīng)該運(yùn)行 RHEL / CentOS 7/8 系統(tǒng)系統(tǒng)系統(tǒng)系統(tǒng)。

b)你應(yīng)該在你的系統(tǒng)中安裝yum程序。

c)您應(yīng)該具有sudo權(quán)限，才能在系統(tǒng)中運(yùn)行特權(quán)命令。

步驟2：更新系統(tǒng)

首先，你需要使用yum update -y命令更新你的系統(tǒng)，如下所示，[root@localhost ~]# yum update -yLoaded plugins: fastestmirror
