rsync备份服务部署

服务端
rsync守护进程服务端配置:
第一个历程: 下载安装软件
[root@backup ~]# rpm -qa|grep rsync
[root@backup ~]# yum install -y rsync
第二个历程: 编写配置文件
[root@backup ~]# man rsyncd.conf ---查看配置文件怎么配置。
[root@backup ~]# vim /etc/rsyncd.conf
uid = rsync
gid = rsync
port = 873
fake super = yes
use chroot = no
max connections = 200
timeout = 300
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log
ignore error
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
[backup]
comment = "backup dir by oldboy"
path = /backup
参数说明：
uid = rsync --- 指定管理备份目录的用户
gid = rsync --- 指定管理备份目录的用户组
port = 873 --- 定义rsync备份服务的网络端口号
fake super = yes --- 将rsync虚拟用户伪装成为一个超级管理员用户
use chroot = no --- 和安全相关的配置
max connections = 200 --- 最大连接数 同时只能有200个客户端连接到备份服务器
timeout = 300 --- 超时时间(单位秒)
pid file = /var/run/rsyncd.pid --- 记录进程号码信息 1.让程序快速停止进程 2. 判断一个服务是否正在运行
lock file = /var/run/rsync.lock --- 锁文件
log file = /var/log/rsyncd.log --- rsync服务的日志文件 用于排错分析问题
ignore errors --- 忽略传输中的简单错误
read only = false --- 指定备份目录是可读可写
list = false --- 使客户端可以查看服务端的模块信息
hosts allow = 172.16.1.0/24 --- 允许传输备份数据的主机(白名单)
hosts deny = 0.0.0.0/32 --- 禁止传输备份数据的主机(黑名单)
auth users = rsync_backup --- 指定认证用户
secrets file = /etc/rsync.password --- 指定认证用户密码文件 用户名称:密码信息
[backup] --- 模块信息
comment = "backup dir by oldboy"
path = /backup --- 模块中配置参数 指定备份目录
第三个历程: 创建rsync服务的虚拟用户
[root@backup ~]# useradd rsync -M -s /sbin/nologin
[root@backup ~]# id rsync
uid=1000(rsync) gid=1000(rsync) groups=1000(rsync)
第四个历程: 创建备份服务认证密码文件
[root@backup ~]# echo "rsync_backup:oldboy123" >/etc/rsync.password
[root@backup ~]# cat /etc/rsync.password
rsync_backup:oldboy123
[root@backup ~]# ll /etc/rsync.password
-rw-r--r-- 1 root root 23 Jan 2 16:37 /etc/rsync.password
[root@backup ~]# chmod 600 /etc/rsync.password
第五个历程: 创建备份目录并修改属主属组信息
[root@backup /]# mkdir backup
[root@backup ~]# chown rsync.rsync /backup
[root@backup ~]# ll /backup -d
drwxr-xr-x 2 rsync rsync 6 Jan 2 16:34 /backup
第六个历程: 启动备份服务
[root@backup ~]# systemctl start rsyncd
[root@backup ~]# systemctl status rsyncd
[root@backup ~]# systemctl enable rsyncd

客户端
rsync守护进程客户端配置:
[root@nfs01 ~]# yum -y install rsync
第一个历程: 创建一个秘密文件
[root@nfs01 ~]# echo "oldboy123" >/etc/rsync.password
[root@nfs01 ~]# chmod 600 /etc/rsync.password
第二个历程: 进行免交互传输数据测试
[root@nfs01 ~]# rsync -avz /etc/hosts [email protected]::backup --password-file=/etc/rsync.password

4. 守护进程服务企业应用:
   a. 守护进程多模块功能配置
   [root@backup ~]# vim /etc/rsyncd.conf
   [backup]
   comment = "backup dir by oldboy"
   path = /backup
   [dba]
   comment = "backup dir by oldboy"
   path = /dba
   [dev]
   comment = "backup dir by oldboy"
   path = /devdata
   [root@backup ~]# mkdir /dba
   [root@backup ~]# mkdir /devdata
   [root@backup ~]# chown rsync.rsync /{dba,devdata}
   [root@backup ~]# ll /{dba,devdata} -d
   drwxr-xr-x 2 rsync rsync 6 Jan 11 10:12 /dba
   drwxr-xr-x 19 rsync rsync 3120 Jan 11 09:57 /devdata
   [root@backup ~]# systemctl restart rsyncd
   [root@nfs01 ~]# rsync -avz /oldboy/ [email protected]::backup --password-file=/etc/rsync.password
   [root@nfs01 ~]# rsync -avz /oldboy/ [email protected]::dev --password-file=/etc/rsync.password
   [root@nfs01 ~]# rsync -avz /oldboy/ [email protected]::dba --password-file=/etc/rsync.passwor
