Rsync timed Backup case

Case

00 per night. Package backup system configuration files, file program directories, and access logs on Web server A and push to Server B for backup retention via the rsync command (backup ideas can be packaged locally by date and then pushed to B), the Web server is packaged for 7 days, and the backup server is retained for 6 months

192.168.88.72--A---Web server

192.168.88.67--b---Backup server

Mkdir/var/html/www/app/logs-p//Create 2 folders in 72, note: WWW is the Service Site directory, logs is 72 access log path

Yum Install rsync//Set rsync on two machines, respectively

I. Creating an RSYNC profile (server 67)

vi/etc/rsyncd.conf//Create Rsync profile and enter the following

#rsync_config_______________start

# #rsyncd. conf start##

UID = rsync

GID = rsync

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 errors

Read Only = False

List = False

Hosts allow = 192.168.88.0/24

Hosts Deny = 0.0.0.0/32

Auth users = Rsync_backup

Secrets file =/etc/rsync.password

[Backup]

Path =/backup

#rsync_config_______________end

: Wq//Save exit

MKDIR/BACKUP-P//Create backup directory

Useradd rsync//Create rsync user

Chown-r rsync.rsync/backup///For backup authorization

Rsync--daemon//start-up service

Lsof-i: 873//Check whether the service is started

echo "Rsync_backup:oldboy" >>/etc/rsync.password//Create password file, note: Rsync_backup,/etc/ Rsync.password must be consistent with configuration file contents (clipping information is recommended), Oldboy as password

chmod 600/etc/rsync.password//Set permissions for password files to 600

Second, client configuration password file 192.168.88.72 (client 72)

echo "Oldboy" >>/etc/rsync.password//Create password file, note: Rsync_backup,/etc/ Rsync.password must be consistent with configuration file contents (clipping information is recommended), Oldboy as password

chmod 600/etc/rsync.password//Set permissions for password files to 600

MKDIR/BACKUP-P//Create backup directory

rsync-avz/backup/[Email protected]::backup--password-file=/etc/rsync.password//test can be pushed, and then 67 to see if the backup directory is pushed successfully

Iii. creating scripts and timed tasks on the client (client 72)

Mkdir/server/scripts//Create a directory to store scripts

Cd/server/scripts//Enter the storage script directory

1, Script (function: Package, push, add successful identity, delete after 7 days of compression package)

VI bak.sh//Common packaging script, fill in the following content

#!/bin/sh

ip=$ (ifconfig eth0|sed-n ' 2p ' |awk-f "[:]+" ' {print $4} ')

[!-d/backup/$ip] && mkdir-p/backup/$ip

cd/backup/$ip &&\

Tar zcf bak_$ (date +%f). tar.gz/var/www/html//app/logs/access_$ (date +%f-d ' -1day '). log/var/spool/cron//etc/

rsync-az/backup/[email protected]::backup--password-file=/etc/rsync.password && Touch ${ip}_flag_$ (Date +% F

rsync-az/backup/[Email Protected]::backup--password-file=/etc/rsync.password

Find/backup-type f-name "*.tar.gz"-mtime +7|xargs rm-f

: Wq//Save exit

See if there is an IP-based directory under both server backup directories

2. Scheduled Tasks

CRONTAB-E//Create a timed task, add the sentence below

XX * * * */bin/sh/server/scripts/bak.sh >/dev/null 2>&1

Iv. creating scripts and timed tasks on the server side (server 67)

Save 60 days after deletion

Mkdir/server/scripts//Create a directory to store scripts

Cd/server/scripts//Enter the storage script directory

1, vi bak.sh//Create a script, add the sentence below

find/backup/-type f-name "*.tar.gz"-mtime +180|xargs rm-f//Remove 6 months of compression pack

2. Scheduled Tasks

CRONTAB-E//Create a timed task, add the sentence below

XX * * 6/bin/sh/server/scripts/bak.sh >/dev/null 2>&1//Every Saturday execution script

Five, timing record backup results check

1, vi/rsyncup.sh//Create a script, add the sentence below

/usr/bin/du-sh/backup/* >>/tmp/rsyncup.log//Check write to Rsyncup.log for timing record backup results

2, CRONTAB-E//Create a timed task, add the sentence below

XX * * 1/bin/sh/server/scripts/rsyncup.sh >/dev/null 2>&1//Every Monday execution script
