Ansible自动化剧本

环境规划

角色   外网IP(NAT)   内网IP(LAN)          部署软件
m01     eth0:10.0.0.61  eth1:172.16.1.61    ansible
backup  eth0:10.0.0.41  eth1:172.16.1.41    rsync
nfs     eth0:10.0.0.31  eth1:172.16.1.31    nfs、Sersync
web01   eth0:10.0.0.7   eth1:172.16.1.7     httpd

本地创建目录

[root@m01 ~]# mkdir /etc/ansible/ansible_playbook/{file,conf,scripts} -p 
[root@m01 ~]# tree /etc/ansible/ansible_playbook/
/etc/ansible/ansible_playbook/
├── conf
└── file
└── scripts

1.基础环境：所有机器统一的配置

1.需要关闭firewalld以及selinux、epel仓库、ssh端口、优化基础配置
2.需要安装rsync和nfs-utils
3.准备www用户
4.需要准备/etc/rsync.pass密码文件
5.需要准备全网备份脚本

基础的playbook剧本

[root@m01 ansible_playbook]# cat base.yaml
- hosts: all
  tasks:
    - name: Install Epel Repos
      get_url: url=http://mirrors.aliyun.com/repo/epel-7.repo dest=/etc/yum.repos.d/epel.repo

    - name: Dns Client
      copy: src=./conf/resolv.conf dest=/etc/resolv.conf

    - name: Install Rsync Nfs-Utils
      yum: name=rsync,nfs-utils state=installed

    - name: Create Group WWW
      group: name=www gid=666

    - name: Create User WWW
      user: name=www uid=666 group=666 create_home=no shell=/sbin/nologin

    - name: Create Rsync_Client_Pass
      copy: content='1' dest=/etc/rsync.pass mode=600

    - name: Create Scripts Directory
      file: path=/server/scripts recurse=yes state=directory

    - name: Push File Scripts
      copy: src=./scripts/rsync_backup_md5.sh dest=/server/scripts/

    - name: Crontable Scripts
      cron: name="backup scripts" hour=01 minute=00 job="/bin/bash /server/scripts/rsync_backup_md5.sh &>/dev/null"

2.应用环境：Rsync

1.安装rsync
2.配置rsync（配置变更，一定要进行重载操作）
3.创建虚拟用户，权限调整
4.创建目录/data/  /backup
5.启动rsync
6.配置邮箱->邮箱的发件人->校验的脚本

rsync应用环境的剧本

[root@m01 ansible_playbook]# cat rsync.yaml
- hosts: backup
  tasks:
   - name: Installed Rsync Server
     yum: name=rsync,mailx state=installed

   - name: configure Rsync Server
     copy: src=./conf/rsyncd.conf dest=/etc/rsyncd.conf
     notify: Restart Rsync Server

   - name: Create Virt User
     copy: content='rsync_backup:1' dest=/etc/rsync.password mode=600

   - name: Create Data
     file: path=/data state=directory recurse=yes owner=www group=www mode=755

   - name: Create Backup
     file: path=/backup state=directory recurse=yes owner=www group=www mode=755

   - name: Start RsyncServer
     service: name=rsyncd state=started enabled=yes

   - name: Push Check Scripts
     copy: src=./scripts/rsync_check_backup.sh dest=/server/scripts/

   - name: Crond Check Scripts
     cron: name="check scripts" hour=05 minute=00 job="/bin/bash /server/scripts/rsync_check_backup.sh &>/dev/null"

 handlers:
   - name: Restart Rsync Server
     service: name=rsyncd state=restarted

3.应用环境：NFS

1.安装nfs-utils
2.配置nfs     （当修改了配置，触发重载操作）
3.创建目录，授权
4.启动

NFS应用环境的剧本

[root@m01 ansible_playbook]# cat nfs.yaml
- hosts: nfs
  tasks:
    - name: Installed Nfs Server
      yum: name=nfs-utils state=installed

    - name: Configure Nfs Server
      copy: src=./conf/exports dest=/etc/exports
      notify: Restart Nfs Server

    - name: Create Share Data
      file: path=/data state=directory recurse=yes owner=www group=www mode=755

    - name: Start Nfs Server
      service: name=nfs-server state=started enabled=yes

  handlers:
    - name: Restart Nfs Server
      service: name=nfs-server state=restarted

4.应用环境：Sersync

1.下载sersync
2.解压，改名，配置
3.启动

Sersync应用环境的剧本

[root@m01 ansible_playbook]# cat sersync.yaml 
- hosts: nfs
  tasks:
    - name: Scp Sersync
      copy: src=./file/sersync2.5.4_64bit_binary_stable_final.tar.gz dest=/usr/local/sersync.tar.gz

    - name: Zip
      shell: cd /usr/local && tar xf sersync.tar.gz && mv GNU-Linux-x86 sersync
      args:
        creates: /usr/local/sersync
    
    - name: configure Sersync
      copy: src=./conf/confxml.xml dest=/usr/local/sersync/

    - name: Start Sersync
      shell: /usr/local/sersync/sersync2 -dro /usr/local/sersync/confxml.xml

5.应用环境：WEB

1、挂载nfs共享的目录

web挂载剧本

[root@m01 ansible_playbook]# cat web.yaml 
- hosts: web
  tasks:
    - name: Mount NFS Server Share Data
      mount: src=172.16.1.31:/data path=/data fstype=nfs opts=defaults state=mounted   

6.包含include

[root@m01 ansible_playbook]# cat mail.yaml 
- import_playbook: base.yaml
- import_playbook: rsync.yaml
- import_playbook: nfs.yaml
- import_playbook: sersync.yaml
- import_playbook: web.yaml

7.对剧本进行测试

1.推送公钥
2.使用ping模块测试
3.执行ansible-playbook测试
4.测试全网备份，测试是否能发邮件，并校验结果
5.测试nfs的挂载
6.测试实时同步
