golang本地执行linux服务器命令(用于自动化部署很 爽哦)
package ssh_connector
import (
"fmt"
"net"

)
func Connect(user, password, host string, port int) (*ssh.Session, error) {
var (
auth []ssh.AuthMethod
addr string
client *ssh.Client
session *ssh.Session
err error
)
// get auth method
auth = make([]ssh.AuthMethod, 0)
auth = append(auth, ssh.Password(password))
// connet to ssh
addr = fmt.Sprintf("%s:%d", host, port)
client, err = ssh.Dial("tcp", addr, &ssh.ClientConfig{

Auth: []ssh.AuthMethod{

},
//需要验证服务端，不做验证返回nil就可以，点击HostKeyCallback看源码就知道了
HostKeyCallback: func(hostname string, remote net.Addr, key ssh.PublicKey) error {
return nil
},
})
// create session
if session, err = client.NewSession(); err != nil {
return nil, err
}
return session, nil
}
