ssh配置config文件命令_config文件能删除吗

# 使用以下命令 一路回车即可
ssh-keygen -t rsa

# 为.ssh目录设置权限
chmod 600 ~/.ssh/config

# config文件需要放到 ~/.ssh/config

Host work1
    HostName 121.0.0.3
	User root
	Port 22

Host work2
    HostName 121.0.0.4
	User root
	Port 22

# 将密钥copy到work1，需要输入work1的登陆密码（此登陆密码为config重配置的user密码）
ssh-copy-id work1 
# 成功后会有如下提示
Now try logging into the machine, with:   "ssh 'work1'"
and check to make sure that only the key(s) you wanted were added.

#现在使用如下即可登陆work1（其他主机方法一样）
ssh work1
