服務(wù)端
rsync守護進程服務(wù)端配置:
第一個歷程: 下載安裝軟件
[root@backup ~]# rpm -qa|grep rsync
[root@backup ~]# yum install -y rsync
第二個歷程: 編寫配置文件
[root@backup ~]# man rsyncd.conf ---查看配置文件怎么配置买决。
[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
參數(shù)說明：
uid = rsync --- 指定管理備份目錄的用戶
gid = rsync --- 指定管理備份目錄的用戶組
port = 873 --- 定義rsync備份服務(wù)的網(wǎng)絡(luò)端口號
fake super = yes --- 將rsync虛擬用戶偽裝成為一個超級管理員用戶
use chroot = no --- 和安全相關(guān)的配置
max connections = 200 --- 最大連接數(shù) 同時只能有200個客戶端連接到備份服務(wù)器
timeout = 300 --- 超時時間(單位秒)
pid file = /var/run/rsyncd.pid --- 記錄進程號碼信息 1.讓程序快速停止進程 2. 判斷一個服務(wù)是否正在運行
lock file = /var/run/rsync.lock --- 鎖文件
log file = /var/log/rsyncd.log --- rsync服務(wù)的日志文件 用于排錯分析問題
ignore errors --- 忽略傳輸中的簡單錯誤
read only = false --- 指定備份目錄是可讀可寫
list = false --- 使客戶端可以查看服務(wù)端的模塊信息
hosts allow = 172.16.1.0/24 --- 允許傳輸備份數(shù)據(jù)的主機(白名單)
hosts deny = 0.0.0.0/32 --- 禁止傳輸備份數(shù)據(jù)的主機(黑名單)
auth users = rsync_backup --- 指定認證用戶
secrets file = /etc/rsync.password --- 指定認證用戶密碼文件 用戶名稱:密碼信息
[backup] --- 模塊信息
comment = "backup dir by oldboy"
path = /backup --- 模塊中配置參數(shù) 指定備份目錄
第三個歷程: 創(chuàng)建rsync服務(wù)的虛擬用戶
[root@backup ~]# useradd rsync -M -s /sbin/nologin
[root@backup ~]# id rsync
uid=1000(rsync) gid=1000(rsync) groups=1000(rsync)
第四個歷程: 創(chuàng)建備份服務(wù)認證密碼文件
[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
第五個歷程: 創(chuàng)建備份目錄并修改屬主屬組信息
[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
第六個歷程: 啟動備份服務(wù)
[root@backup ~]# systemctl start rsyncd
[root@backup ~]# systemctl status rsyncd
[root@backup ~]# systemctl enable rsyncd
客戶端
rsync守護進程客戶端配置:
[root@nfs01 ~]# yum -y install rsync
第一個歷程: 創(chuàng)建一個秘密文件
[root@nfs01 ~]# echo "oldboy123" >/etc/rsync.password
[root@nfs01 ~]# chmod 600 /etc/rsync.password
第二個歷程: 進行免交互傳輸數(shù)據(jù)測試
[root@nfs01 ~]# rsync -avz /etc/hosts rsync_backup@192.168.10.18::backup --password-file=/etc/rsync.password
- 守護進程服務(wù)企業(yè)應(yīng)用:
a. 守護進程多模塊功能配置
[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/ rsync_backup@192.168.10.18::backup --password-file=/etc/rsync.password
[root@nfs01 ~]# rsync -avz /oldboy/ rsync_backup@192.168.10.18::dev --password-file=/etc/rsync.password
[root@nfs01 ~]# rsync -avz /oldboy/ rsync_backup@192.168.10.18::dba --password-file=/etc/rsync.passwor
