主服务器端，向从服务器端实时同步数据
master端IP地址：192.168.1.39（node1）
slave端IP地址：192.168.1.40 (node2)
一、配置从服务器
- 在从服务器安装rsync，创建并配置rsync文件。
[[email protected] ~]# yum install -y rsync hosts allow = 192.168.1.39 hosts deny = * list = true uid = root gid = root pid file = /var/run/rsyncd.pid lock file = /var/run/rsync.lock log file = /var/log/rsyncd.log [node2] path = /data/node2 read only = no
2.在从服务器上创建需要同步的文件目录，并且启动rsync,查看进程和监听的端口。
[[email protected] ~]# mkdir -p /data/node2 [[email protected] ~]# rsync --daemon [[email protected] ~]# ps -ef | grep rsync| grep -v "grep" root 1723 1 0 22:17 ? 00:00:00 rsync --daemon [[email protected] ~]# netstat -anpt | grep rsync tcp 0 0 0.0.0.0:873 0.0.0.0:* LISTEN 1723/rsync tcp 0 0 :::873 :::* LISTEN 1723/rsync
3.手动测试rsync同步功能。
[[email protected] ~]# cd /data/node2/ [[email protected] node2]# echo "123456">a.txt [[email protected] node2]# echo "abcd">b.txt [[email protected] node2]# cat a.txt b.txt 123456 abcd [[email protected] ~]# yum install -y rsync（在master上安装rsync） [[email protected] ~]# mkdir -p /data/node1 [[email protected] ~]# rsync -avzP 192.168.1.40::node2 /data/node1/ receiving incremental file list ./ a.txt 7 100% 6.84kB/s 0:00:00 (xfer#1, to-check=1/3) b.txt 5 100% 0.12kB/s 0:00:00 (xfer#2, to-check=0/3) sent 68 bytes received 180 bytes 23.62 bytes/sec total size is 12 speedup is 0.05 [[email protected] ~]# cd /data/node1/ [[email protected] node1]# ls a.txt b.txt [[email protected] node1]# cat a.txt b.txt 123456 abcd 手动测试同步成功。
二、配置主服务器
- 编译安装inotify。
[[email protected] ~]# mkdir -p /taokey/tools [[email protected] ~]# cd /taokey/tools/ [[email protected] tools]# tar -zxf inotify-tools-3.14.tar.gz [[email protected] tools]# cd inotify-tools-3.14 [[email protected] inotify-tools-3.14]# ./configure [[email protected] inotify-tools-3.14]# make [[email protected] inotify-tools-3.14]# make install
2.配置inotify脚本。
#!/bin/bash
host=192.168.1.40
data_dir=/data/node1/
dst=node2
/usr/local/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
#rsync -avzP $host::$dst $data_dir
rsync -avzP --delete --progress $data_dir $host::$dst
echo "${files} was rsynced" >> /tmp/rsync.log 2>&1
done
[[email protected] inotify-tools-3.14]# chmod u+x inotify_rsync.sh
[[email protected] inotify-tools-3.14]# bash inotify_rsync.sh &
[1] 4533
[[email protected] inotify-tools-3.14]# ps -ef | grep inoti | grep -v "grep"
root 4533 1880 0 18:02 pts/1 00:00:00 bash inotify_rsync.sh
root 4534 4533 0 18:02 pts/1 00:00:00 /usr/local/bin/inotifywait -mrq --timefmt %d/%m/%y %H:%M --format %T %w%f%e -e modify,delete,create,attrib /data/node1/
root 4535 4533 0 18:02 pts/1 00:00:00 bash inotify_rsync.sh
3.在主服务器上往从服务器上同步数据，测试。
[[email protected] ~]# cd /data/node1/ [[email protected] node1]# ls a.txt b.txt [[email protected] node1]# touch c.txt [[email protected] node1]# sending incremental file list ./ c.txt 0 100% 0.00kB/s 0:00:00 (xfer#1, to-check=0/4) sent 111 bytes received 30 bytes 13.43 bytes/sec total size is 12 speedup is 0.09 sending incremental file list sent 72 bytes received 8 bytes 7.62 bytes/sec total size is 12 speedup is 0.15 [[email protected] node1]# [[email protected] node2]# ls a.txt b.txt c.txt [r[email protected] node1]# rm -rf a.txt [[email protected] node1]# sending incremental file list ./ deleting a.txt sent 61 bytes received 11 bytes 6.86 bytes/sec total size is 5 speedup is 0.07 [[email protected] node1]# [[email protected] node2]# ls b.txt c.txt 试验成功！
