每天晚上12点整备份全网所有机器的系统配置文件和web服务器上的程序文件至备份服务器上
1)所有服务器的备份目录必须都为/backup。
2)要备份的系统配置文件包括但不限于:
a.定时任务服务的配置文件(/var/spool/cron/root)(适合web和nfs服务器)。
b.开机自启动的配置文件(/etc/rc.local)(适合web和nfs服务器)。
c.日常脚本的目录 (/server/scripts)(适合web和nfs服务器)。
d.防火墙iptables的配置文件(/etc/sysconfig/iptables)(适合web和nfs服务器)
e.其它一些需要备份的目录
3)Web服务器站点目录假定为(/var/html/www)。
4)Web服务器A访问日志路径假定为(/app/logs)
5)Web服务器保留打包后的7天的备份数据即可(本地留存不能多于7天,因为太多硬盘会满)
6)备份服务器上,保留每周一的所有数据副本,其它要保留6个月的数据副本。
7)备份服务器上要按照备份数据服务器的内网IP为目录保存备份,备份的文件按照时间名字保存。
8)需要确保备份的数据尽量完整正确,在备份服务器上对备份的数据进行检查,把备份的成功及失败结果信息发给系统管理员邮箱中

## 4.2 rsync客户端准备工作
## 4.21 准备客户端密码认证文件
```bash
[root@m01:/etc/ansible/rsync_client]# echo "123456" >rsync.password
[root@m01:/etc/ansible/rsync_client]# chmod 600 rsync.password
1)用来备份系统文件的脚本
[root@m01: ~]# vim /etc/ansible/rsync_client/backup_sys.sh
#!/bin/bash
#
#backup_sys script
#write by michaelni 2018-06-06
Backup_dir="/backup"
IP_info=$(hostname -I)
## hostname -I查看内网网址,此处也可以使用awk进行过滤,也可以写成IP_info=`hostname -I`
# creat backup dir
mkdir -p $Backup_dir/$IP_info
# tar backup data
cd /
tar zchf $Backup_dir/$IP_info/system_backup_$(date +%F_week%w -d -"1day").tar.gz ./var/spool/cron/root ./etc/rc.local ./server/scripts ./etc/sysconfig/iptables
#del 7 day ago data
find $Backup_dir -type f -name +7|xargs rm 2>/dev/null
##有可能会出现不存在七天之前的文件,此时删除会报错,所以将报错重定向为空
#creat finger file
find $Backup_dir/ -type f -mtime -1 ! -name "finger*"|xargs md5sum >$Backup_dir/$IP_info/finger.txt
##查找一天内的文件排除指纹文件(不对指纹文件进行校验)生成MD5校验值并重定向到校验值文件中
#backup push data info
rsync -az $Backup_dir/ rsync_backup@192.168.81.165::backup --password-file=/etc/rsync.password
2)用来备份服务应用数据的脚本
[root@m01: ~]# vim /etc/ansible/rsync_client/backup_web.sh
#!/bin/bash
#
#bacup_web_data script
#write by michaelni 2018-06-06
Backup_dir="/backup"
IP_info=$(hostname -I)
# creat backup dir
mkdir -p $Backup_dir/$IP_info
# tar backup data
cd /
tar zchf $Backup_dir/$IP_info/system_backup_$(date +%F_week%w -d -"1day").tar.gz ./var/spool/cron/root ./etc/rc.local ./server/scripts ./etc/sysconfig/iptables
tar zchf $Backup_dir/$IP_info/www_backup_$(date +%F_week%w -d -"1day").tar.gz ./var/html/www
tar zchf /$Backup_dir/$IP_info/www_log_backup_$(date +%F_week%w -d -"1day").tar.gz ./app/logs
#del 7 day ago data
find $Backup_dir -type f -name +7|xargs rm 2>/dev/null
#creat finger file
find $Backup_dir/ -type f -mtime -1 ! -name "finger*"|xargs md5sum >$Backup_dir/$IP_info/finger.txt
#backup push data info

[root@m01:~]# cd /etc/ansible/roles/
[root@m01:/etc/ansible/roles]# mkdir -p {rsync,rsync_server,rsync_client}/{tasks,vars,files,handlers,templates}
[root@m01:/etc/ansible/roles]# vim rsync/tasks/main.yml
- name: 01-install rsync
yum: name=rsync state=installed
1)编写tasks目录下的main.yml
[root@m01:/etc/ansible/roles]# vim rsync_server/tasks/main.yml
- name: 01-push conf file & password file & bash file
template: src={{ item.src }} dest={{ item.dest }} mode={{ item.mode }}

shell: netstat -lntup | grep {{ Port_info }}
register: get_server_port
- name: 06-display port info
debug: msg={{ get_server_port.stdout_lines }}
- name: 07-set crontab
cron: minute=5 hour=0 name=‘rsync backup‘ job=‘/bin/bash /server/scripts/backup_server.sh &>/dev/null‘
2)编写vars目录下的main.yml
[root@m01: roles]# vim rsync_server/vars/main.yml
backupdir: /backup
Port_info: 873
passfile: rsync.password
scripts: backup_server.sh
3)准备files目录下的相关文件(包括配置文件,密码认证,脚本文件等)
[root@m01 roles]# cp -a /etc/ansible/rsync_server/* rsync_server/files/
[root@m01 roles]# ll ./rsync_server/files/
total 12
-rwxr-xr-x 1 root root 463 Apr 4 00:22 backup_server.sh
-rw-r--r-- 1 root root 530 Apr 3 23:35 rsyncd.conf
-rw------- 1 root root 23 Apr 4 00:17 rsync.password
4)编写templates目录下的相关文件
[root@m01 roles]# cp -a /etc/ansible/roles/rsync_server/files/* ./rsync_server/templates/
[root@m01 roles]# vim ./rsync_server/templates/rsyncd.conf
uid = rsync
gid = rsync
port = {{ Port_info }}
fake super = yes
use chroot = no
max connections = 200
timeout = 300
pid file = /var/run/rsyncd.pid

auth users = rsync_backup
secrets file = /etc/{{ passfile }}
[backup]
comment = "backup dir by michaelni"
path = {{ backupdir }}
read_only = false
5)编写handlers目录下的main.yml
[root@m01:roles]# vim rsync_server/handlers/main.yml
- name: restart rsyncd
service: name=rsyncd state=restarted
## 5.23 rsync_client部分
```bash
1)编写tasks目录下的main.yml
[root@m01: roles]# vim /etc/ansible/roles/rsync_client/tasks/main.yml
- name: 01-create scripts dir
file: path=/server/scripts/ state=directory
- name: 02-push passfile & scriptfile
template: src={{ item.src }} dest={{ item.dest }} mode={{ item.mode }}
with_items:
- { src: ‘{{ passfile }}‘, dest: ‘/etc/‘, mode: ‘600‘ }
- { src: ‘{{ scripts }}‘, dest: ‘/server/scripts/‘, mode: ‘755‘ }

- name: 04-set crontab
cron: minute=0 hour=0 name=‘rsync backup‘ job=‘/bin/bash /server/scripts/{{ scripts }} &>/dev/null‘
2)编写vars目录下的main.yml
[root@m01: roles]# vim /etc/ansible/roles/rsync_client/vars/main.yml
passfile: rsync.password
scripts: backup_sys.sh
#scripts: backup_web.sh
Port_info: 873
3)将客户端需要的文件准备好放到files目录下
[root@m01:/etc/ansible/roles]# cp -a ../rsync_client/* /etc/ansible/roles/rsync_client/files/
4)编写templates目录下文件
[root@m01:/etc/ansible/roles]# cp rsync_client/files/* rsync_client/templates/
[root@m01 templates]# vim backup_sys.sh
.......略........
rsync -az $Backup_dir/ rsync_backup@192.168.81.165::backup --port= {{ Port_info }} --password-file=/etc/ {{ passfile }}
[root@m01 templates]# vim backup_web.sh
.......略........
rsync -az $Backup_dir/ rsync_backup@192.168.81.165::backup --port= {{ Port_info }} --password-file=/etc/ {{ passfile }}
5.24 编写raync主剧本文件
[root@m01 roles]# vim /etc/ansible/roles/site_rsync.yml
- hosts: rsync
roles:
- rsync
- hosts: rsync_server
roles:
- rsync_server
- hosts: rsync_client
roles:
- rsync_client
5.25 测试
测试:将端口号改为999,看看配置文件和脚本里的端口是否更改,能否正常备份数据
[root@m01 roles]# vim rsync_server/vars/main.yml
[root@m01 roles]# vim rsync_client/vars/main.yml
passfile: rsync.password
scripts: backup.sh
Port_info: 888
