测试基于salt-ssh的密码及密钥

uytyrt

这里先记录下下今天对salt-ssh关于密码以密钥的测试情况（后期完善）

1 2 3 4 5 6 7

操作系统版本： [iyunv@master ~]# cat /etc/redhat-release CentOS release 6.7 (Final) 主机信息： master: 10.10.10.140（安装salt-ssh） node01: 10.10.10.141 node01：10.10.10.142

基于密码验证的测试过程：
a、安装epel源以及salt-ssh

1 2	[iyunv@master ~]# rpm -ivh http://dl.fedoraproject.org/pub/ ... ease-6-8.noarch.rpm [iyunv@master ~]# yum -y install salt-ssh

b、配置salt-ssh配置文件

1 2 3 4 5 6 7 8 9

[iyunv@master ~]# vim /etc/salt/roster node01:   host: 10.10.10.141   user: root            passwd: redhat12345   node02:   host: 10.10.10.142   user: root           passwd: redhat12345

c、使用salt-ssh进行测试

1 2 3 4 5 6 7 8 9 10 11 12 13

[iyunv@master salt]# salt-ssh '*' test.ping [WARNING ] Failed to open log file, do you have permission to write to /var/log/salt/master? node01:     True node02:     True [iyunv@master salt]# salt-ssh '*' cmd.run 'uptime' [WARNING ] Failed to open log file, do you have permission to write to /var/log/salt/master? node01:      05:33:37 up 23 min,  1 user,  load average: 0.17, 0.05, 0.02 node02:      21:33:42 up 23 min,  1 user,  load average: 0.16, 0.06, 0.02 说明:这里由于我没有安装salt-master，出现没有日志文件权限的警告信息，可以忽略

基于密钥验证的测试过程：

a、配置免密钥登录：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35

[iyunv@master ~]# ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: 19:65:dc:fa:72:33:35:d6:81:18:e0:91:d3:ce:ce:0f root@master.saltstack.com The key's randomart image is: +--[ RSA 2048]----+ |         +*oo .  | |        .=oo.. . | |        ..+.   ..| |         o.o  + .| |        S o. o . | |          .E=    | |           ooo   | |             .   | |                 | +-----------------+ [iyunv@master ~]# scp ~/.ssh/id_rsa.pub root@10.10.10.141:/root/ root@10.10.10.141's password: id_rsa.pub                                   100%  407     0.4KB/s   00:00    [iyunv@master ~]# scp ~/.ssh/id_rsa.pub root@10.10.10.142:/root/ root@10.10.10.142's password: id_rsa.pub                                   100%  407     0.4KB/s   00:00    [iyunv@node01 ~]# cat id_rsa.pub >>~/.ssh/authorized_keys [iyunv@node01 ~]# service sshd restart 停止 sshd：                                                [确定] 正在启动 sshd：                                            [确定] [iyunv@node02 ~]# cat id_rsa.pub >>~/.ssh/authorized_keys [iyunv@node02 ~]# service sshd restart 停止 sshd：                                                [确定] 正在启动 sshd：                                            [确定]

b、调整salt-ssh的配置文件

1 2 3 4 5 6 7

为了测试密钥登录，而不是在配置文件中写好密码登录，重新调整下/etc/salt/roster文件，将密码的部分注销掉 [iyunv@master ~]# vim /etc/salt/roster # Sample salt-ssh config file node01:   host: 10.10.10.141 node02:   host: 10.10.10.142

c、基于密钥的配置：

1 2 3 4 5 6 7 8

[iyunv@master ~]# ssh-copy-id -i /etc/salt/pki/master/ssh/salt-ssh.rsa.pub root@10.10.10.141 Now try logging into the machine, with "ssh 'root@10.10.10.141'", and check in:   .ssh/authorized_keys to make sure we haven't added extra keys that you weren't expecting. [iyunv@master ~]# ssh-copy-id -i /etc/salt/pki/master/ssh/salt-ssh.rsa.pub root@10.10.10.142 Now try logging into the machine, with "ssh 'root@10.10.10.142'", and check in:   .ssh/authorized_keys to make sure we haven't added extra keys that you weren't expecting.

d、测试实验效果：

1 2 3 4 5 6 7 8 9 10 11 12 13 14

[iyunv@master ~]# salt-ssh '*' cmd.run 'df -h' [WARNING ] Failed to open log file, do you have permission to write to /var/log/salt/master? node02:     Filesystem      Size  Used Avail Use% Mounted on     /dev/sda5        14G  8.3G  4.6G  65% /     tmpfs           932M     0  932M   0% /dev/shm     /dev/sda1       190M   42M  139M  23% /boot     /dev/sda3       2.0G   18M  1.8G   1% /tmp node01:     Filesystem      Size  Used Avail Use% Mounted on     /dev/sda5        14G  8.3G  4.6G  65% /     tmpfs           932M   72K  932M   1% /dev/shm     /dev/sda1       190M   42M  139M  23% /boot     /dev/sda3       2.0G   18M  1.8G   1% /tmp
