任务：一键执行Rsync全网备份、NFS共享目录、sersync实时同步三个服务
ansible官网链接：https://docs.ansible.com/ansible/latest/modules/modules_by_category.html
有些繁琐，欢迎提出问题。
一、守护进程+全网备份
##在完成一键批量执行服务前要保证SSH远程连接服务秘钥分发成功
1.配置ansible主机列表
1.书写分发秘钥脚本保证SSH远程连接服务
2.修改邮件配置文件并推送到backup服务器
3.m01批量管理机本地创建客户端全网备份的脚本
4.m01批量管理机本地创建服务端发送邮件的脚本
5.m01批量管理机本地创建剧本执行 先保证客户端nfs01 web01 web02与服务端backup保证守护进程模式，再进行全网备份。
添加主机列表到/etc/ansible/hosts
[02:15 root@m01 ~]# vim /etc/ansible/hosts
[oldboy]
172.16.1.7
172.16.1.8
172.16.1.31
[web]
172.16.1.7
172.16.1.8
[nfs]
172.16.1.31
[backup]
172.16.1.411.本地创建分发秘钥脚本并执行
[21:49 root@m01 /etc/ansible]# vim /server/scripts/fenfa_pub.sh
#!/bin/bash
#make key pair
ssh-keygen -t dsa -f ~/.ssh/id_dsa -P ''
#fenfa public key
for ip in 7 8 41 31
do
sshpass -p123456 ssh-copy-id -o StrictHostKeyChecking=no 172.16.1.$ip
done
#ansible
ansible all -m shell -a "hostname"2.修改rsync.conf配置文件
[21:51 root@m01 /etc/ansible]# cat /etc/ansible/file/rsyncd.conf
##Rsync server
##created by oldboy 15:01 2009-6-5
##rsyncd.conf start##
uid = rsync
gid = rsync
use chroot = no
fake super = yes
max connections = 2000
timeout = 600
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log
ignore errors
read only = false
list = false
hosts allow = 172.16.1.0/24
#hosts deny = 0.0.0.0/32
auth users = rsync_backup
secrets file = /etc/rsync.password

#####################################
[nfsbackup]
comment = www by old0boy 13:14 2019-5-20
path = /nfsbackup3.创建客户端端脚本：
[21:52 root@m01 /etc/ansible]# cat /server/scripts/rsync_backup.sh
#!/bin/bash
. /etc/profile
#定义变量
IP=$(hostname -I|awk '{print $2}')
HOSTNAME=$(hostname)
#创建目录
mkdir -p /backup/$IP
#打包备份系统配置文件
tar zcf /backup/$IP/`date +%F-%w`.tar.gz /var/spool/cron/root /var/l
og/messages /var/log/cron /var/log/rsyncd.log /etc/rc.local /etc/fst
ab /etc/hosts /server/scripts
#md5校验信息
find /backup/ -type f -name "*.tar.gz"|xargs md5sum >/backup/$IP/$HOSTNAME.md5
#保留7天内的备份
find /backup/ -type f -mtime +7 -name "*.tar.gz"|xargs rm -rf
#推送到备份服务器
rsync -avz /backup/ rsync_backup@172.16.1.41::backup --password-file=/etc/rsync.password4.创建服务端发送邮件的脚本
[22:04 root@m01 /etc/ansible]# vim /server/scripts/backup.sh
#!/bin/bash
. /etc/profile
#校验md5信息
find /backup/ -type f -name "*.md5"|xargs md5sum -c >/backup/md5.txt
#删除180天前的
find /backup/ -type f -name "*.tar.gz" ! -name "*-6.tar.gz" -mtime +180|xargs rm -rf
#发送邮件
mail -s " Rsync Backup 完成 该下班拉" 245684979@qq.com </backup/md5.txt5.在backup服务端安装mailx软件
然后在邮箱配置文件/etc/mail.rc追加此邮箱配置
把此文件推送到backup服务器上，覆盖源文件
[22:05 root@m01 /etc/ansible]#ansible backup -m yum -a 'name=mailx state=present' \\安装邮箱
[22:05 root@m01 /etc/ansible]# cat >>/etc/mail.rc <<EOF \\追加配置内容
> set from=lichenxing0430@163.com
> set smtp=smtp.163.com
> set smtp-auth=login
> set smtp=auth-user=lichenxing0430
> set smtp-auth-password=\\密码
> set smtp-auth=login
> EOF6.本地创建剧本文件rsync_backup.yml进行全网配置

可以在剧本中定时任务改为每分钟，单个拿出模块测试一下是否能备份，是否可以收到邮件。
–start-at-task=模块名 指定任务执行
ansible-playbook rsync_backup.yml --start-at-task="mail-cron" 检查剧本※二、批量部署nfs服务（服务端 客户端）
1.书写分发秘钥脚本保证SSH远程连接服务
5.本地创建剧本执行nfs网络文件系统服务
1.本地创建分发秘钥脚本并执行
如果已经批量分发过秘钥，此步不需要执行
[03:00 root@m01 /etc/ansible]# vim /server/scripts/fenfa_pub.sh

#make key pair
ssh-keygen -t dsa -f ~/.ssh/id_dsa -P ''

do

ansible-playbook -C sersync.yml 检查剧本
剧本可能会有很多瑕疵，欢迎补充。

把rsync全网备份服务 nfs网络文件共享服务 sersync实时同步服务都放到一个脚本中执行

ansible-playbook /etc/ansible/sersync.yml克隆四台全新的虚拟机测试一下吧：
web01 web02 nfs01 backup
修改主机名 IP地址 做基础优化 关闭防火墙
这种一条走到头的感觉非常爽，有种上厕所的通畅感，终于搞定了！
