一、服务节点安装inotify-tools。
确保系统后以下输出=>
[root@xxxx]# ll /proc/sys/fs/inotify/
total 0
-rw-r--r-- 1 root root 0 Aug 23 20:02 max_queued_events
-rw-r--r-- 1 root root 0 Aug 23 20:02 max_user_instances
-rw-r--r-- 1 root root 0 Aug 23 20:02 max_user_watches
(1)yum -y install inotify-tools.x86_64
(2)配置server端的inotify监测脚本
<1>cat /opt/zkrsync/rsyncfile.sh
#!/bin/bash
host_pubbak=10.0.138.136 src=/data/zookeeper
dest_pubbak=zkpub
user=root /bin/inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f%e' -e close_write,delete,create,attrib $src \
| while read file
do
/bin/rsync -vzrtopg --delete --progress $src $user@$host_pubbak::$dest_pubbak
echo "${$(date +%Y%m%d_%H%M%S)} ${files} was rsynced" >> /tmp/rsync.log 2>&1
done
sh /opt/zkrsync/rsyncfile.sh &
<2>supervisord配置
cat /etc/supervisord.d/rsync.ini
[program:rsync]
command=/opt/zkrsync/rsyncfile.sh
startsecs=3
startretries=3
stopsignal=QUIT
stopasgroup=true
stopwaitsecs=10
user=root
redirect_stderr=true
stdout_logfile=/data/log/rsync/running.log
stdout_logfile_maxbytes=50MB
stdout_logfile_backups=10
stderr_logfile=/data/log/rsync/error.log
stderr_logfile_maxbytes=50MB
stderr_logfile_backups=10
二、客户端
(1)rsync配置文件设置
cat /etc/rsyncd.conf
uid = root
gid = root
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log
[zkpub]
path = /tmp
comment = zk transaction log trans
read only = no
hosts allow = 10.0.138.152 #server端ip
hosts deny = *
(2)启动rsync进程服务
rsync --daemon --config=/etc/rsyncd.conf -v
三、 测试
向这个目录"/tmp/test"进行文件的增删改查操作,日志样例如下:
sending incremental file list
test/
deleting test/wuwu sent 40 bytes received 12 bytes 104.00 bytes/sec
total size is 0 speedup is 0.00
sending incremental file list
test/
test/iiii
5 100% 0.00kB/s 0:00:00 (xfer#1, to-check=0/2)
测试ok没有问题。
