集群管理工具ansible常用命令

使用ansible过程如下：

主控端：安装ansible

# install the epel-release RPM if needed on CentOS, RHEL, or Scientific Linux

[root@tidb01 ~]# yum install epel-release[root@tidb01 ~]# yum -y install ansible[root@tidb01 ~]# ansible --version

ansible 2.9.10  config file = /etc/ansible/ansible.cfg  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']  ansible python module location = /usr/lib/python2.7/site-packages/ansible  executable location = /usr/bin/ansible  python version = 2.7.5 (default, Apr 11 2018, 07:36:10) [GCC 4.8.5 20150623 (Red Hat 4.8.5-28)]

配置hosts，添加被管控的主机

[root@tidb01 ~]# cat /etc/ansible/hosts

[servers]192.168.30.101192.168.30.102#192.168.30.103#192.168.30.104192.168.30.105#192.168.30.106

生成密钥

[root@tidb01 ~]# ssh-keygen

使用ssh-copy-id命令来复制ansible公钥到各个节点

[root@tidb01 ~]# ssh-copy-id root@192.168.30.101[root@tidb01 ~]# ssh-copy-id root@192.168.30.102[root@tidb01 ~]# ssh-copy-id root@192.168.30.105

执行ping命令

[root@tidb01 ~]# ansible servers -m ping#或：[root@tidb01 ~]# ansible servers -i /etc/ansible/hosts -m ping#或：[root@tidb01 ~]# ansible -m ping servers#或：[root@tidb01 ~]# ansible -m ping all

192.168.30.102 | SUCCESS => {    "ansible_facts": {        "discovered_interpreter_python": "/usr/bin/python"    },     "changed": false,     "ping": "pong"}192.168.30.105 | SUCCESS => {    "ansible_facts": {        "discovered_interpreter_python": "/usr/bin/python"    },     "changed": false,     "ping": "pong"}192.168.30.101 | SUCCESS => {    "ansible_facts": {        "discovered_interpreter_python": "/usr/bin/python"    },     "changed": false,     "ping": "pong"}

指定用户，执行ping命令

[root@tidb01 ~]# ssh-copy-id chen@192.168.30.101[root@tidb01 ~]# ssh-copy-id chen@192.168.30.102[root@tidb01 ~]# ssh-copy-id chen@192.168.30.105[root@tidb01 ~]# ansible all -m ping -u chen

192.168.30.105 | SUCCESS => {    "ansible_facts": {        "discovered_interpreter_python": "/usr/bin/python"    },     "changed": false,     "ping": "pong"}192.168.30.102 | SUCCESS => {    "ansible_facts": {        "discovered_interpreter_python": "/usr/bin/python"    },     "changed": false,     "ping": "pong"}192.168.30.101 | SUCCESS => {    "ansible_facts": {        "discovered_interpreter_python": "/usr/bin/python"    },     "changed": false,     "ping": "pong"}
