配置ssh密钥快速登录远程服务器

ssh_key_config.sh

# 1.生成密钥
ssh-keygen -t rsa

# 2.拷贝公钥id_rsa.pub到远程服务器的用户.ssh目录下(这里远程服务器是Mac OSX)
scp ~/.ssh/id_rsa.pub {remote_username}@{remote_ip}:~/{remote_username}/.ssh/

# 3.重命名远程服务器上的id_rsa.pub为authorized_keys
mv id_rsa.pub authorized_keys

# 4.编辑本地配置文件
vim ~/.ssh/config
# 5.输入如下命令并保存
Host {alias}
Hostname {remote_ip}
Port 22
User {local_username}
IdentityFile ~/.ssh/id_rsa

# 5.这样就可以通过ssh {alias}来快速登录远程服务器而不需要每次都输入密码了
