Enter file in which to save the key (C:\Users\fucheng/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in C:\Users\fucheng/.ssh/id_rsa. Your public key has been saved in C:\Users\fucheng/.ssh/id_rsa.pub. The key fingerprint is: SHA256:9OlHGn5uIlELfGIYXdWectiEV5XS2quWpD1qpd2QJC8 [email protected] The key's randomart image is: +---[RSA 2048]----+ | . ....o..=| | . . ..+o | | +. *+. | | ..=.oooo=. | | .S=+.=o. .| | .o.E * . | | .+ @ = | | . .B.B . | | ..++ . | +----[SHA256]-----+一般情况下不需要输入密码,直接回车即可。 执行完ssh-keygen之后会在,用户目录下的.ssh文件下,生成一个id_rsa文件和id_rsa.pub文件。 id_rsa文件是私钥,要保存好,放在本地,私钥可以生产公钥,反之不行。id_rsa.pub文件是公钥,可以用于发送到其他服务器,或者git上。 2 ssh设置无密码登录服务器将之前在本地生成的公钥id_rsa.pub,发送到需要无密码登录的服务器,然后将id_rsa.pub的内容追加到服务器的~/.ssh/authorized_keys文件中即可。 如果没有.ssh目录,创建一个就好,或者执行ssh localhost登录本地,ssh会自动创建。 可以使用如下命令进行操作: $ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys另外如果想要无密码登录本地localhost,那么在本地执行上面的命令即可,执行之后再 ssh localhost 就不需要输入密码了。 3 设置ssh无密码访问git仓库注意这里访问的主要是私有仓库。 以github为例,找到个人主页,点击[settings],找到[SSH and GPG keys] ,新建SSH keys,将本地id_rsa.pub的内容复制到key里面,tittle可以随便填写,这样就配置好了。 找到要访问的仓库主页,点击Clone or Download 将use Http换成use SSH,然后就会显示对应的仓库地址如:[email protected]:uername/xxxxx.git 使用该地址就可以在本地进行无密码访问仓库了。 |
