首先環境說明

1.部署rsync+inotify同步/dxk目錄至目標伺服器/tmp/dxk下

部署rsync服務同步

首先環境說明

部署rsync+inotify同步/qinyong目錄至目標伺服器/tmp/qinyong下
源伺服器

一、關閉源伺服器和目標伺服器的防火牆和SELINUX

1.源伺服器和目標伺服器

[[email protected] ~]# systemctl stop firewalld（源伺服器）
[[email protected] ~]# getenforce 
Disabled
[[email protected] ~]# systemctl stop firewalld（目標伺服器）
[[email protected] ~]# getenforce
Disabled

二、安裝rsync

[[email protected] ~]# yum install rsync -y
 

三、目標伺服器配置

1.建立使用者認證檔案

[[email protected] run]# echo 'qinyong.'>/etc/rsync.pass
[[email protected] run]# cat /etc/rsync.pass 
root:qy5247479-

2.修改rsyncd.conf配置檔案

[[email protected] ~]# cat >> /etc/rsyncd.conf <<EOF
> log file = /var/log/rsyncd.log
> pidfile = /var/run/rsyncd.pid
> lock file = /var/run/rsync.lock
> secrets file = /etc/rsync.pass
> [qinyong] 
> path = /nihao/
> comment = sync etc from client
> uid = root
> gid = root
> port = 873
> ignore errors
> use chroot = no
> read only = no
> list = no
> max connections = 200
> timeout = 600
> auth users = root
> EOF
 

3.設定檔案許可權

[[email protected] ~]# chmod 600 /etc/rsync*
[[email protected] ~]# ll /etc/rsync*
-rw------- 1 root root 793 9月  19 10:03 /etc/rsyncd.conf
-rw------- 1 root root  16 9月  19 10:06 /etc/rsync.pass

4.啟動rsync服務並設定為開機自啟

[[email protected] ~]# systemctl start rsyncd
[[email protected] ~]# systemctl enable rsyncd
Created symlink from /etc/systemd/system/multi-user.target.wants/rsyncd.service to /usr/lib/systemd/system/rsyncd.service.

四、源伺服器配置

1.安裝rsync服務端軟體

[[email protected] ~]# yum install epel-release -y

2.建立認證密碼檔案，並設定許可權為600

[[email protected] ~]# echo 'qy5247479-' > /etc/rsync.pass
[[email protected] ~]# chmod 600 /etc/rsync.pass 
[[email protected] ~]# ll /etc/rsync.pass
-rw------- 1 root root 8 9月  19 10:32 /etc/rsync.pass

3.建立測試目錄，執行命令

[[email protected] ~]# mkdir -pv /root/nihao
mkdir: 已建立目錄 "/root/nihao"
[[email protected] ~]# rsync -avH --port 873 --progress --delete /root/nihao/ [email protected]::nihao --password-file=/etc/rsync.pass
sending incremental file list
./
.inotify.sh.swp
          4,096 100%    0.00kB/s    0:00:00 (xfr#1, to-chk=4/6)
abc
             20 100%   26.53kB/s    0:00:00 (xfr#2, to-chk=3/6)
nohup.out
            151 100%  230.46kB/s    0:00:00 (xfr#3, to-chk=2/6)
123/
aaaa/

sent 4,586 bytes  received 92 bytes  9,356.00 bytes/sec
total size is 4,267  speedup is 0.91

4.安裝inotify-tools

[[email protected] ~]# yum install inotify-tools

5.配置同步指令碼

[[email protected] ~]# mkdir /scripts
[[email protected] ~]# cd /scripts/
[[email protected] scripts]# touch inotify.sh
[[email protected] scripts]# chmod 755 inotify.sh 
[[email protected] scripts]# vim inotify.sh 

host=192.168.100.129
src=/root/nihao
des=qinyong
password=/etc/rsync.pass
user=root
inotifywait=/usr/bin/inotifywait
$inotifywait -mrq --timefmt '%Y%m%d %H:%M' --format '%T %w%f%e' -e modify,delete,create,attrib $src \
| while read files ;do
 rsync -avzP --delete --timeout=100 --password-file=${password} $src $u
[email protected]$host::$des
 echo "${files} was rsynced" >>/tmp/rsync.log 2>&1
done

6.啟動指令碼

[[email protected] scripts]# nohup bash /scripts/inotify.sh &
[1] 59758

五、驗證結果

1.源伺服器

[[email protected] ~]# cd nihao/
[[email protected] nihao]# ls
55  da  hehe  nohup.out

2.目標伺服器

[[email protected] tmp]# cd /qinyong/
[[email protected] qinyong]# ls
55  da  hehe  nohup.out

3.源伺服器

[[email protected] nihao]# mkdir qinyong
[[email protected] nihao]# ls
dad  555  aaa nihao  nohup.out
[[email protected] nihaoi]# touch lala

4.目標伺服器

[[email protected] qinyong]# ls
dad  555  aaa nihao  nohup.out lala
