ansible的问题

1 密码报错
如果密码是全数字，ansible的inventory是不支持的

2 用户报错
如果远程用户的没有/home/***目录，或者没有该目录的读写权限，会报错

3 未连接主机报错
有三种方法：

• gedit /etc/ansible/ansible.cfg or ~/.ansible.cfg
  [defaults]
  host_key_checking = False

• export ANSIBLE_HOST_KEY_CHECKING=False
  

•  ansible-playbook -e 'host_key_checking=False' yourplaybook.yml
  

4 页面大透明的禁止

• name: Disable transparent huge pages on all nodes defrag
  lineinfile: dest=/etc/rc.d/rc.local regexp='^.transparent_hugepage.$' line='echo never > /sys/kernel/mm/transparent_hugepage/defrag'

• name: Disable transparent huge pages on all nodes enabled
  lineinfile: dest=/etc/rc.d/rc.local regexp='^.transparent_hugepage.$' line='echo never > /sys/kernel/mm/transparent_hugepage/enabled'

5 重启并等待返回

• name: restart machine
  shell: sleep 2 && shutdown -r now "Ansible updates triggered"
  async: 1
  poll: 0
  sudo: true
  ignore_errors: true

• name: waiting for server to come back
  local_action: wait_for host=all state=started delay=10 timeout=50
  sudo: false

6 安装openssl

• name: copy openssl rpm
  copy: src=openssl-1.0.1e-42.el6_7.4.x86_64.rpm dest=/temp/httpd/openssl-1.0.1e-42.el6_7.4.x86_64.rpm

• name: openssl rpm
  yum: name=/temp/httpd/openssl-1.0.1e-42.el6_7.4.x86_64.rpm state=present
