On the Jenkins Master node:
[root@* ~]# cat /etc/passwd | grep jenkins

jenkins:x:997:995:Jenkins Automation Server:/var/lib/jenkins:/bin/false

[root@* ~]# vim /etc/passwd

将“jenkins:x:997:995:Jenkins Automation Server:/var/lib/jenkins:/bin/false”替换为“jenkins:x:997:995:Jenkins Automation Server:/var/lib/jenkins:/bin/bash”

[root@* ~]# passwd jenkins

Changing password for user jenkins.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.

[root@* ~]# vim /etc/ssh/sshd_config

...
PasswordAuthentication yes
...

[root@* ~]# sudo systemctl restart sshd

[root@* ~]# su - jenkins

-bash-4.2$ pwd
/var/lib/jenkins

-bash-4.2$ ssh-keygen

Generating public/private rsa key pair.
Enter file in which to save the key (/var/lib/jenkins/.ssh/id_rsa): 
Created directory '/var/lib/jenkins/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /var/lib/jenkins/.ssh/id_rsa.
Your public key has been saved in /var/lib/jenkins/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:*** jenkins@ip-10-0-0-*.us-west-2.compute.internal
The key's randomart image is:
+---[RSA 2048]----+
...
+----[SHA256]-----+

-bash-4.2$ ssh-copy-id jenkins@localhost

/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/var/lib/jenkins/.ssh/id_rsa.pub"
/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
jenkins@localhost's password: 

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'jenkins@localhost'"
and check to make sure that only the key(s) you wanted were added.

-bash-4.2$ ssh localhost

-bash-4.2$ exit

-bash-4.2$ exit
logout

[root@* ~]# visudo
在
## Allow root to run any commands anywhere
root ALL=(ALL) ALL
下面再加一行：

jenkins ALL=(ALL) NOPASSWD: ALL

Note
在vim里按“/”键，进入搜索模式。

再开启一台ECS（CentOS7），作为Jenkins Slave node。

SSH login to this server.
[centos@* ~]$ sudo su -

[root@jenkinsslave ~]# adduser jenkins

[root@jenkinsslave ~]# passwd jenkins

Changing password for user jenkins.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.

[root@jenkinsslave ~]# visudo

在
## Allow root to run any commands anywhere
root ALL=(ALL) ALL
的下面再加一行：

jenkins ALL=(ALL) NOPASSWD: ALL

[root@jenkinsslave ~]# vim /etc/ssh/sshd_config

...
PasswordAuthentication yes
...

[root@jenkinsslave ~]# sudo systemctl restart sshd

On the Jenkins Master node

[root@* ~]# su - jenkins

使用Jenkins Slave node的内网IP地址。拷贝到Jenkins Slave node。
-bash-4.2$ ssh-copy-id jenkins@10.0.0.x

/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/var/lib/jenkins/.ssh/id_rsa.pub"

jenkins@10.0.0.*'s password: 

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'jenkins@10.0.0.*'"
and check to make sure that only the key(s) you wanted were added.

-bash-4.2$ ssh 10.0.0.x

[jenkins@jenkinsslave ~]$ exit
