二、OpenSSH简介 🏆

OpenSSH(OpenBSD Secure Shell)是使用SSH透过计算机网络加密通信的实现。它是取代由SSH Communications Security所提供的商用版本的开放源代码方案。目前OpenSSH是OpenBSD的子项目。

OpenSSH常常被误认以为与OpenSSL有关系,但实际上这两个项目有不同的目的,不同的发展团队,名称相近只是因为两者有同样的软件发展目标──提供开放源代码的加密通信软件。

三、OpenSSH安装操作 🎈

1、清除缓存并更新YUM源 🥇

[root@centos ~]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: base extras updates
Cleaning up list of fastest mirrors

[root@centos ~]# yum repolist
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirrors.aliyun.com
 * extras: mirrors.aliyun.com
 * updates: mirrors.aliyun.com
repo id                                      repo name                                                            status
base/7/x86_64                                CentOS-7 - Base - mirrors.aliyun.com                                 10,072
extras/7/x86_64                              CentOS-7 - Extras - mirrors.aliyun.com                                  500
updates/7/x86_64                             CentOS-7 - Updates - mirrors.aliyun.com                               3,190
repolist: 13,762

2、查看原来SSH版本信息并卸载 🔎

[root@centos ~]# rpm -qa | grep ssh
openssh-clients-7.4p1-21.el7.x86_64
openssh-7.4p1-21.el7.x86_64
openssh-server-7.4p1-21.el7.x86_64
libssh2-1.8.0-4.el7.x86_64

[root@centos ~]# ssh -V
OpenSSH_7.4p1, OpenSSL 1.0.2k-fips  26 Jan 2017

[root@centos ~]# rpm -qa | grep openssh | xargs rpm -e --nodeps
[root@centos ~]# rpm -qa | grep openssh
[root@centos ~]#

3、本地下载OpenSSH镜像包并上传至Linux系统 📺


(或者采用步骤4,二者取其一即可)



下载链接:

image-20211214124003962

4、使用wget命令下载OpenSSH安装包 🔗

💥

复制链接地址。

💥


https://mirrors.aliyun.com/openssh/portable/openssh-8.8p1.tar.gz

image-20211214124322822



使用wget命令下载。

🔍

6、修改相关参数 📚

[root@centos openssh-8.8p1]# cd /etc/init.d/
[root@centos init.d]# cp /root/openssh-8.8p1/contrib/redhat/sshd.init /etc/init.d/sshd

[root@centos init.d]# vi /etc/ssh/sshd_config
添加如下内容
#PasswordAuthentication yes
PermitRootLogin yes
[root@centos init.d]#chmod 600 /etc/ssh/*

7、启动并查看SSH服务 📞 🧰
