流程分析

1.安装ansible
2.优化ansible
3.推送公钥
4.开启防火墙
5.开启80 443 873 nfs等端口和服务白名单
6.关闭selinux
7.创建同一的用户
	1.安装sersync
	2.拷贝sersync配置文件
	3.配置rsync密码文件
	4.启动sersync

推送公钥

1.创建密钥对
[root@m01 ~]# ssh-keygen
2.推送公钥
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]

ansible优化

1.下载
[root@m01 ~]#  yum install -y ansible
2.优化
[root@m01 ~]#  vim /etc/ansible/ansible.cfg		#改为
host_key_checking = False

配置主机清单

[root@m01 ~]# vim /root/ansible/hosts 
#[]标签名任意，但是最好不要用特殊符号（- | &）和大写字母，中文（不能是nginx）
#端口是22的时候可以省略
[web_group]
172.16.1.7 ansible_ssh_port=22 asible_ssh_user=root ansible_ssh_pass='1'
172.16.1.8 ansible_ssh_port=22 asible_ssh_user=root ansible_ssh_pass='1'

sersync配置文件

编辑tasks目录

1.安装sersync
[root@m01 sersync]# vim tasks/install.yml 
- name: check nfs-utils inotify-tools
  shell: "rpm -q nfs-utils && rpm -q inotify-tools"
  ignore_errors: yes
  register: check_nfs_inotify

- name: install nfs inotify
  yum:
    name: "{{ item }}"
    state: present
  when: check_nfs_inotify.rc != 0
  loop:
    - "nfs-utils"
    - "inotify-tools"

- name: get sersync packages
  get_url:
    url: "http://test.driverzeng.com/other/sersync2.5.4_64bit_binary_stable_final.tar.gz"
    dest: "/tmp"

- name: jieya sersync packages
  unarchive:
    src: "/tmp/sersync2.5.4_64bit_binary_stable_final.tar.gz"
    dest: /usr/local
    copy: no
2.创建监控目录
[root@m01 sersync]# vim tasks/dir.yml 
- name: create  watch_data
  file:
    path: /{{ watch_data }}
    state: directory
    recurse: yes
3.创建密码文件
[root@m01 sersync]# vim tasks/pass.yml 
- name: backup server pass
  copy:
    content: "{{ rsync_pass }}"
    dest: /etc/rsync.passwd
    owner: root
    group: root
    mode: 0600
4.拷贝配置文件
[root@m01 sersync]# vim tasks/config.yml 
- name: copy sersync.conf
  template:
    src: sersync.j2
    dest: /usr/local/GNU-Linux-x86/confxml.xml
    backup: yes
5.启动
[root@m01 sersync]# vim tasks/start.yml 
- name: start sersync
  shell: /usr/local/GNU-Linux-x86/sersync2 -rdo /usr/local/GNU-Linux-x86/confxml.xml
6.include
[root@m01 sersync]# vim tasks/main.yml 
- include: install.yml
- include: dir.yml
- include: config.yml
- include: pass.yml
- include: start.yml

编辑入口文件

[root@m01 roles]# vim site.yml 
- hosts: all
  roles:
    #- { role: base }
    #- { role: rsync_client,when: ansible_fqdn is match 'web*' }
    #- { role: rsync_client,when: ansible_fqdn is match 'nfs*' }
    #- { role: rsync_server,when: ansible_fqdn is match 'backup*' }
    #- { role: nfs_server,when: ansible_fqdn is match 'nfs*' }
    #- { role: nfs_client,when: ansible_fqdn is match 'web*' }
    #- { role: mount_server,when: ansible_fqdn is match 'nfs*' }
    #- { role: mount_client,when: ansible_fqdn is match 'web*' }
    - { role: sersync,when: ansible_fqdn is match 'nfs*' }

执行

[root@m01 roles]# ansible-playbook site.yml
