(Mac異常) localhost: ssh: connect to host localhost port 22: Connection refused

前言

今天啓動Mac上的Spark, 運行start-all.sh. 報出瞭如下異常類型. 個人猜測是本地端口的問題.

# 測試命令
ssh localhost
//ssh: connect to host localhost port 22: Connection refused

解決措施

• 配置本地到本地的ssh (不知道是否需要？)

# 生成本地密碼
ssh-keygen -t rsa
# 將本地公鑰匙寫入認證地址
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

• 開啓配置

sudo systemsetup -f -setremotelogin on

• 測試

SeandeMacBook-Pro:~ sean$ ssh localhost
