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。
