記一次線上數據同步 不用模塊和祕鑰文件，通過兩臺服務器之間做互信的方式在同步文件。 首先拷貝發送端的公鑰到接收端上面
# ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Created directory '/root/.ssh'. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: eb:1d:9a:b9:d8:42:ab:2e:7c:31:eb:7d:24:69:81:a4 [email protected] The key's randomart image is: +--[ RSA 2048]----+ | | | . | | o . | | E . . | | oS | | o = .. | | . * +. . | | o o.o+.= . | | =+.ooB.. | +-----------------+
# vim .ssh/id_rsa.pub
這裏我直接複製到接收端的.ssh/authorized_keys文件中。因爲是複製的，很可能會自動換行。需要手動調整。 將其調整問一行，當然你把發送端的公鑰文件scp到接收端上，然後重命名文件爲authorized_keys也是可以的。 測試互信是否成功 以/tmp文件夾下的文件做同步測試

加入inotify實現增量同步，腳本如下
# auth_rsync.sh
#!/bin/bash
user1="root"
host1="119.23.211.200"
dst1="/data"
src="/data/"
/soft/inotify/bin/inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f' -e modify,delete,create,attrib ${src} | while read files
do
nohup /usr/bin/rsync -vzrtopg --progress ${src} ${user1}@${host1}:${dst1}
echo "${files} was rsynced" >> /var/log/rsync.log 2>&1
done修改權限
# chmod 755 auth_rsync.sh
添加開機啓動
# cp auth_rsync.sh /etc/init.d/ # chkconfig --add /etc/init.d/auth_rsync.sh
以守護進程啓動腳本並放在後臺運行
# nohup /etc/init.d/auth_rsync.sh > /tmp/rsync.log 2>&1 &
