rsync

Posted 2020-12-11 syy1757528181

使用roles实现一键部署rsync

环境

主机名	wanIP	lanIP	服务	角色
m01	10.0.0.61	172.16.1.61	Ansible	控制端
backup	10.0.0.41	172.16.1.41	rsync服务端	被控端
web01	10.0.0.7	172.16.1.7	rsync客户端	被控端
web02	10.0.0.8	172.16.1.8	rsync客户端	被控端
nfs	10.0.0.31	172.16.131	rsync客户端	被控端

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.web backup nfs 安装rsync
2.拷贝rsync配置文件
3.创建服务端backup的备份目录
4.copy密码文件
5.把客户端密码加入环境全局变量文件
6.启动rsync，并加入开机自启动

########################### rsync服务端roles（rsync_server）

使用ansible-galaxy命令创建角色目录

[root@m01 ansible]# ansible-galaxy init rsync_server

编辑meta目录

[root@m01 rsync_server]# vim meta/main.yml 
dependencies:
  - { role: base }

编辑tasks目录

1.使用ansible-galaxy命令创建roles目录
[root@m01 roles]# ansible-galaxy init rsync_server
2.编辑tasks目录中的‘.yml文件‘
[root@m01 rsync_server]# vim tasks/install.yml 
- name: panduan rsync install
  shell: "rpm -q rsync"
  register: rsync_install

- name: install rsync
  yum:
    name: rsync
    state: present
  when: rsync_install.rc != 0
3.拷贝rsync配置文件
[root@m01 rsync_server]# vim tasks/config_rsync.yml 
- name: config rsync
  template:
    src: rsyncd.j2
    dest: /etc/rsyncd.conf
  notify:
    - restart rsyncd server
4.创建相关目录
[root@m01 rsync_server]# vim tasks/create_file.yml 
- name: Create Backup Dir
  file:
    path: /{{ user_dir_mk }}
    recurse: yes
    owner: www
    group: www
    mode: 0755
    state: directory
5.创建rsync服务端密码文件
[root@m01 rsync_server]# vim tasks/server.pass.yml 
- name: Create PASS File
  copy:
    content: "{{ user_dir_mk }}:{{ rsync_pass }}"
    dest: /etc/rsync.passwd
    owner: root
    group: root
    mode: 0600
6.创建启动文件
[root@m01 rsync_server]# vim tasks/start.yml 
- name: start rsyncd
  service:
    name: rsyncd
    state: started
    enabled: yes
7.编辑tasks/main.yml
[root@m01 rsync_server]# vim tasks/main.yml 
- include: install.yml
- include: client.pass.yml
- include: source.yml
- include: config_rsync.yml
- include: create_file.yml
- include: server.pass.yml
- include: start.yml

编辑template目录

[root@m01 rsync_server]# vim templates/rsyncd.j2 
uid = www
gid = www
port = 873
fake super = yes
use chroot = no
max connections = 200
timeout = 600
ignore errors
read only = false
list = false

auth users = {{ user_dir_mk }}
secrets file = /etc/rsync.passwd
log file = /var/log/rsyncd.log
[{{ user_dir_mk }}]

comment = welcome to oldboyedu backup!
path = /{{ user_dir_mk }}

编辑vars目录

[root@m01 rsync_server]# vim vars/main.yml 
rsync_pass: 123
user_dir_mk: backup

编辑handlers目录

[root@m01 rsync_server]# vim handlers/main.yml 
- name: restart rsyncd server
  service:
    name: rsyncd
    state: restarted
    enabled: true

编辑入口文件

[root@m01 roles]# vim rsync_server.yml 
- hosts: backup_group
  roles:
    - { role: base }
    - { role: rsync_server }

执行

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

########################### rsync客户端roles（rsync_clicent）

编辑meta目录

[root@m01 rsync_client]# vim meta/main.yml 
dependencies:
  - { role: base }

编辑tasks目录

1.使用ansible-galaxy命令创建roles目录
[root@m01 roles]# ansible-galaxy init rsync_client
2.编辑tasks目录中的‘.yml文件‘
[root@m01 rsync_client]# vim tasks/install.yml 
- name: panduan rsync install
  shell: "rpm -q rsync"
  register: rsync_install

- name: install rsync
  yum:
    name: rsync
    state: present
  when: rsync_install.rc != 0
3.拷贝客户端密码
[root@m01 rsync_client]# vim tasks/client.pass.yml 
- name: selicent pass
  copy:
    content: ‘export RSYNC_PASSWORD={{ rsync_pass }}‘
    dest: /etc/profile.d/rsync.pass
    owner: root
    group: root
    mode: 0600
4.source客户端，使密码文件立即生效
[root@m01 rsync_client]# vim tasks/source.yml 
- name: sourse
  shell: "source /etc/profile.d/rsync.pass"
5.创建相关目录
[root@m01 rsync_client]# vim tasks/create_file.yml 
- name: Create Backup Dir
  file:
    path: /{{ user_dir_mk }}
    recurse: yes
    owner: www
    group: www
    mode: 0755
    state: directory

- hosts: backup_group
  roles:
    - { role: rsync_client }

执行

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

注意

1.使用loop代替with_items循环变量的话不会出现粉色警告

2.不同角色中的变量不会冲突
