/etc/rsyncd.conf
[root@localhost data]# cat /etc/rsyncd.conf uid=root gid=root use chroot=no max connections=10 strict modes=yes port=873 address=192.168.137.129 (host IP) read only=no list=no pid file=/var/run/rsyncd.pid lock file=/var/run/rsync.lock log file=/var/log/rsyncd.log [case] （moduble） path = /opt/data comment = ucweb-file
1. Create a file
[root@localhost data]# >1.txt [root@localhost data]# >2.txt [root@localhost data]# >3.txt [root@localhost data]# [root@localhost data]# ls 1.txt 2.txt 3.txt
2. Synchronize all files (note: case, is the module configured in rsyncd.conf of 128)
[root@localhost data]# rsync -auvz /opt/data [email protected]::case sending incremental file list data/ data/1.txt data/2.txt data/3.txt sent 190 bytes received 69 bytes 518.00 bytes/sec total size is 0 speedup is 0.00
3. Sync the modified files
[root@localhost data]# vi 1.txt [root@localhost data]# rsync -auvz /opt/data [email protected]::case sending incremental file list data/ data/1.txt sent 132 bytes received 31 bytes 326.00 bytes/sec total size is 6 speedup is 0.04
Conclusion: It is suitable for synchronizing small files, because the contents of the files are compared each time they are synchronized, and the performance may be reduced when encountering large files (untested)
Generally, it works better with inotify-tools.
