基于远程shell 实现 sersync
#不需要配置rsync daemon,只需要配置基于key验证的ssh即可
[root@data-centos8 ~]#ssh-keygen
[root@data-centos8 ~]#ssh-copy-id backup-server
#下载sersync，并拷贝至相应的目录，设置PATH变量同5.5.2
#修改sersync配置文件
[root@data-centos8 ~]#cat /usr/local/sersync/confxml.xml

[root@data-centos8 ~]#sersync2 -dro /usr/local/sersync/confxml.xml
set the system param
execute：echo 50000000 > /proc/sys/fs/inotify/max_user_watches
execute：echo 327679 > /proc/sys/fs/inotify/max_queued_events
parse the command param
option: -d run as a daemon
option: -r rsync all the local files to the remote servers before the sersync work
option: -o config xml name： /apps/sersync/confxml.xml
daemon thread num: 10
parse xml config file
host ip : localhost host port: 8008
daemon start，sersync run behind the console
config xml parse success
please set /etc/rsyncd.conf max connections=0 Manually
sersync working thread 12 = 1(primary thread) + 1(fail retry thread) + 10(daemon sub threads)
Max threads numbers is: 22 = 12(Thread pool nums) + 10(Sub threads)
please according your cpu ，use -n param to adjust the cpu rate
------------------------------------------
rsync the directory recursivly to the remote servers once
working please wait...
execute command: cd /data/www && rsync -auz -R --delete ./ -e ssh 10.0.0.18:/data/backup >/dev/null 2>&1
run the sersync:
watch path is: /data/www本文链接：https://www.yunweipai.com/36031.html
