一、linux 6.5
-
同步目录备份文件的客户端
-
安装rsync xinetd
yum -y install xinetd rsync
-
创建并配置rsyncd.conf
vi /etc/rsyncd.conf
-
创建帐号密码文件
echo test:test123 > /etc/rsyncd.passwd
uid = root
gid = root
use chroot = no
max connections = 100
log file = /var/run/rsyncd.log
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsyncd.lock
[rsync]
path = /home/share_backup/
comment = rsync
list = yes
read only = no
port = 873
timeout = 200
write only = no
auth users = test
secrets file = /etc/rsyncd.passwd
ignore errors = yes
hosts allow = 192.168.1.2 ##服务端的IP
-
启动
/etc/init.d/xinetd start
/usr/bin/rsync --daemon --config=/etc/rsyncd.conf
建议设置为开机自启动在/etc/rc.local下
-
存储文件的服务端
-
安装inotify
yum -y install epel-release
yum -y install inotify-tools
-
创建密码文件
echo test123 > /etc/rsyncd.passwd
-
自定义目录下创建脚本文件
vi inotify.sh
#!/bin/bash
host=192.168.1.1 ###客户端的IP
data_dir=/home/files/ ##存源文件的目录
dst=rsync
username=test
/usr/bin/inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f%e' -e modify,delete,create,attrib $data_dir | while read files
do
/usr/bin/rsync -vzrtopg --delete --progress --password-file=/etc/rsyncd.passwd $data_dir $username@$host::$dst
echo "${files} was rsynced" >> /tmp/rsync.log 2>&1 #写入日志
done
-
启动脚本
bash inotify.sh &
建议设置为开机自启动在/etc/rc.local下
-
测试以及注意事项
1 在服务端的/home/files/创建文件，查看客户端是否同步。
2 注意selinux iptables等限制。
二、linux 7
-
同步目录备份文件的客户端
-
安装与linux6.5类似
-
rsyncd.conf 配置
vim /etc/rsyncd.conf
uid = root
gid = root
use chroot = no
max connections = 2000
pid file = /var/run/rsyncd.pid
exclude = lost+found/
transfer logging = yes
timeout = 200
log file = /var/run/rsyncd.log
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsyncd.lock
log format = %t %a %m %f %b
[rsync]
path = /var/www/html //必须存在
comment = rsync
list = yes
read only = no
write only = no
auth users = test
secrets file = /etc/rsyncd.secret
ignore errors = yes
hosts allow = *
-
创建帐号密码文件 并启动
echo test:test123 > /etc/rsyncd.secret
/usr/bin/rsync --daemon --config=/etc/rsyncd.conf
-
存储文件的服务端
-
安装
1.yum -y install epel-release
yum -y install inotify-tools
-
创建密码文件
echo test123 > /etc/rsyncd.secret
文件夹 /var/www/html 存在
-
后台执行脚本
host=192.168.122.8 //服务端ip
src=/var/www/html
dst=rsync
user=test
rsync_passfile=/etc/rsyncd.secret
inotify_home=/usr/
if [ ! -e "$src" ] \
|| [ ! -e "${rsync_passfile}" ] \
|| [ ! -e "${inotify_home}/bin/inotifywait" ] \
|| [ ! -e "/usr/bin/rsync" ];
then
echo "Check File and Directory"
exit 9
fi
${inotify_home}/bin/inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f' -e close_write,delete,create,attrib $src \
| while read file
do
rsync -avzP --delete --timeout=100 --password-file=${rsync_passfile} $src $user@$host::$dst >/dev/null 2>&1
cd $src && rsync -aruz -R --delete ./ --timeout=100 $user@$host::$dst --password-file=${rsync_passfile} >/dev/null 2>&1
done
exit 0
-
测试：在客户端/var/www/html下创建文件，查看服务端是否同步
