批量实现多台服务器之间ssh无密码登录的相互信任关系, 可以参考之前的文章: https://www.cnblogs.com/kevingrace/p/9063745.html这里采用Ansible 实现批量建立互信, 方法如下:首先要生成ansible服务端本机ssh的key[root@ansible-server ~]# ssh-keygen -t rsa //一路回车[root@ansible-server ~]# ls /root/.ssh/id_rsa id_rsa.pub====================================================需要注意ssh建立互信的命令格式:# ssh-copy-id -i ~/.ssh/id_rsa.pub username@[ip,hostname]====================================================在客户机比较多的情况下，使用 ssh-copy-id命令的方法显然是有些费时，使用ansible-playbook 推送 ymal进行批量创建ssh互信关系就显得省事多了，这里就使用到了ansible的authoried_keys 模块:首先要配置ansible清单 (远程主机的密码这里为"123456")[root@ansible-server ~]# vim /etc/ansible/hosts................................[ssh-host]172.16.60.204172.16.60.205172.16.60.206172.16.60.207[ssh-host:vars]ansible_ssh_pass="123456"==========================================================发送公钥到目标机器命令格式如下:# ansible ssh-host -m copy -a "src=/root/.ssh/id_rsa.pub dest=/root/.ssh/authorized_keys mode=600"==========================================================编写playbook文件[root@ansible-server ~]# vim /opt/ssh_key.yaml--- - hosts: ssh-host user: root tasks: - name: ssh-copy authorized_key: user=root key="{{ lookup(‘file‘, ‘/root/.ssh/id_rsa.pub‘) }}"注意上面yaml脚本中的"ssh-key-host"是在/etc/ansible/hosts清单文件里配置的远程客户机列表这里做的是基于远程主机root用户的ssh互信执行批量互信[root@ansible-server ~]# ansible-playbook /opt/ssh_key.yamlPLAY [ssh-host] ************************************************************************************************************************TASK [Gathering Facts] *****************************************************************************************************************ok: [172.16.60.204]ok: [172.16.60.205]ok: [172.16.60.206]ok: [172.16.60.207]TASK [ssh-copy] ************************************************************************************************************************changed: [172.16.60.205]changed: [172.16.60.204]changed: [172.16.60.206]changed: [172.16.60.207]PLAY RECAP *****************************************************************************************************************************172.16.60.204 : ok=2 changed=1 unreachable=0 failed=0 172.16.60.205 : ok=2 changed=1 unreachable=0 failed=0 172.16.60.206 : ok=2 changed=1 unreachable=0 failed=0 172.16.60.207 : ok=2 changed=1 unreachable=0 failed=0最后验证下ssh互信[root@ansible-server ~]# ansible -i /etc/ansible/hosts ssh-host -m shell -a "whoami"172.16.60.204 | SUCCESS | rc=0 >>root172.16.60.205 | SUCCESS | rc=0 >>root172.16.60.207 | SUCCESS | rc=0 >>root172.16.60.206 | SUCCESS | rc=0 >>root至此, ansible批量创建到远程客户机的ssh信任关系已经实现了! |

由于在使用ansible修改用户密码的时候不能使用明文的方式，需要先加密，所以就需要使用一个方法对输入的明文的密码进行加密.废话不多说了. 下面直接记录下操作方法:[root@ansible-server ~]# vim /opt/root_passwd.yaml--- - hosts: ssh-host gather_facts: false tasks: - name: change user passwd user: name={{ item.name }} password={{ item.chpass | password_hash(‘sha512‘) }} update_password=always with_items: - { name: ‘root‘, chpass: ‘kevin@123‘ } - { name: ‘app‘, chpass: ‘bjop123‘ }注意上面在yaml文件中修改了远程客户机的root用户密码, app用户密码.如果还想要修改其他用户密码, 则继续按照上面规则添加即可!执行ansible-play[root@ansible-server ~]# ansible-playbook /opt/root_passwd.yamlPLAY [ssh-host] ************************************************************************************************************************TASK [change user passwd] **************************************************************************************************************changed: [172.16.60.204] => (item={u‘chpass‘: u‘kevin@123‘, u‘name‘: u‘root‘})changed: [172.16.60.205] => (item={u‘chpass‘: u‘kevin@123‘, u‘name‘: u‘root‘})changed: [172.16.60.204] => (item={u‘chpass‘: u‘bjop123‘, u‘name‘: u‘app‘})changed: [172.16.60.205] => (item={u‘chpass‘: u‘bjop123‘, u‘name‘: u‘app‘})changed: [172.16.60.206] => (item={u‘chpass‘: u‘kevin@123‘, u‘name‘: u‘root‘})changed: [172.16.60.206] => (item={u‘chpass‘: u‘bjop123‘, u‘name‘: u‘app‘})changed: [172.16.60.207] => (item={u‘chpass‘: u‘kevin@123‘, u‘name‘: u‘root‘})changed: [172.16.60.207] => (item={u‘chpass‘: u‘bjop123‘, u‘name‘: u‘app‘})PLAY RECAP *****************************************************************************************************************************172.16.60.204 : ok=1 changed=1 unreachable=0 failed=0 172.16.60.205 : ok=1 changed=1 unreachable=0 failed=0 172.16.60.206 : ok=1 changed=1 unreachable=0 failed=0 172.16.60.207 : ok=1 changed=1 unreachable=0 failed=0 |
方法二: 修改远程主机的单个用户密码使用此方法比较方便

编写playbook文件[root@ansible-server ~]# vim /opt/root_passwd2.yaml--- - hosts: ssh-host gather_facts: false tasks: - name: Change password user: name={{ name1 }} password={{ chpass | password_hash(‘sha512‘) }} update_password=always执行ansible-playbook, 使用-e参数传递用户名和密码给剧本，其中root为用户名，admin#123就是修改后的root密码[root@ansible-server ~]# ansible-playbook /opt/root_passwd2.yaml -e "name1=root chpass=admin#123" PLAY [ssh-host] ************************************************************************************************************************TASK [Change password] *****************************************************************************************************************changed: [172.16.60.204]changed: [172.16.60.205]changed: [172.16.60.206]changed: [172.16.60.207]PLAY RECAP *****************************************************************************************************************************172.16.60.204 : ok=1 changed=1 unreachable=0 failed=0 172.16.60.205 : ok=1 changed=1 unreachable=0 failed=0 172.16.60.206 : ok=1 changed=1 unreachable=0 failed=0 172.16.60.207 : ok=1 changed=1 unreachable=0 failed=0 |

如果ansible服务端没有和远程主机做ssh信任关系, 则可以在hosts清单配置里直接指明用户名和密码.如果使用普通用户, 并且允许sudo, 则需要提前在客户机里的/etc/sudoers文件里配置好该普通用户的sudo配置, 即允许该普通用户有sudo权限. [root@ansible-server ~]# vim /etc/ansible/hosts................[test-host]172.16.60.220 ansible_ssh_user=root ansible_ssh_pass=123456 ansible_ssh_port=22172.16.60.221 ansible_ssh_user=root ansible_ssh_pass=bo@123 ansible_ssh_port=22172.16.60.222 ansible_ssh_user=app ansible_ssh_pass=bj@123 ansible_ssh_port=22 ansible_sudo_pass=bj@123 即172.16.60.220客户机上要提前配置, 允许app用户具有sudo权限.执行:[root@ansible-server ~]# ansible test-host -m shell -a "hostname" 172.16.60.222 | SUCCESS | rc=0 >>k8s-node02172.16.60.220 | SUCCESS | rc=0 >>k8s-master01172.16.60.221 | SUCCESS | rc=0 >>k8s-node01[root@ansible-server ~]# ansible -i /etc/ansible/hosts test-host -m shell -a "hostname"172.16.60.222 | SUCCESS | rc=0 >>k8s-node02172.16.60.220 | SUCCESS | rc=0 >>k8s-master01172.16.60.221 | SUCCESS | rc=0 >>k8s-node01 |
