ssh

最初是在找mac上的ssh软件，但看到一个用iterm和ssh config的设置

常规配置

正常设置

?

1 2 3 4 5 6 7 8 9

Host *    Port 22    ServerAliveInterval 120   Host target     HostName $HOST     Port $PORT     IdentityFile ~/.ssh/id_rsa     User $USER

$分别指代自己对应的端口号、用户名等等

免密登录

事例：

ssh-copy-id -i ~/.ssh/id_rsa.pub -p 11040 root@183.232.159.7

可能会遇到设置了也没用的情况，得检查目标机器的sshd config是否开启密钥登录：

1.登录目标机器

2.vim /etc/ssh/sshd_config

3.修改配置

PasswordAuthentication yes

RSAAuthentication yes

PubkeyAuthentication yes

4.重启sshd服务

systemctl restart sshd

跳板机设置

?

1 2 3 4 5 6 7 8 9 10 11

Host gateway     HostName $GATEWAY_HOST     Port $GATEWAY_PORT     IdentityFile ~/.ssh/id_rsa     User $GATEWAY_USER   Host target     HostName $TARGET_HOST     User $TARGET_USER     IdentityFile ~/.ssh/id_rsa     ProxyCommand ssh gateway nc %h %p 2> /dev/null # 或者 ProxyCommand ssh gateway -W %h:%p

?

1 2	%h 表示 hostname %p 表示 port

ssh target 'mkdir -p .ssh && cat > .ssh/authorized_keys' < ~/.ssh/id_rsa.pub

ssh target
scp some_file target:/home/user
rsync -avP * target:/home/user/some_dir
