Server-side
1, install rsync on both sides to do
Yum Install-y rsync
Vi/etc/rsyncd.conf #服务器端
port=873
Log File=/var/log/rsync.log
PID File=/var/run/rsyncd.pid
#address =192.168.0.10
Max connections=10
Timeout = 300
[Webbak]
Path=/tmp/www/wordpress
Use Chroot=true
Read Only=no
List=false
Uid=root
Gid=root
#auth Users=test
#secrets file=/etc/rsyncd.passwd
Hosts allow=192.168.1.109
#hosts deny = 0.0.0.0/32

echo "Rsync--daemon" >>/etc/rc.local
#启动服务
Rsync--daemon

2, install Inotify-tools tools, real-time trigger rsync synchronization
Both machines have to be done.
Installing Inotify-tools
Yum install-y make GCC gcc-c++
cd/mydata/download/
Wget-c http://github.com/downloads/rvoicilas/inotify-tools/inotify-tools-3.14.tar.gz
Tar zxvf inotify-tools-3.14.tar.gz
CD inotify-tools-3.14
Mkdir-p/usr/local/inotify
./configure--prefix=/usr/local/inotify
Make
Make install
Setting system environment variables, adding soft connections
echo "path= $PATH:/usr/local/inotify/bin" >>/etc/profile.d/inotify.sh
Source/etc/profile.d/inotify.sh #使设置立即生效
echo "/usr/local/inotify/lib" >/etc/ld.so.conf.d/inotify.conf && ldconfig
Ln-s/usr/local/inotify/include/usr/include/inotify
Modify inotify default parameter (inotify default kernel parameter value is too small)
Vi/etc/sysctl.conf
fs.inotify.max_queued_events=99999999
fs.inotify.max_user_watches=99999999
fs.inotify.max_user_instances=65535
/sbin/sysctl-p

3. Installation Configuration Sersync
Cd/download

</sersync>

Add the command to the/etc/rc.local and restart the system later to sync normally
Vi/etc/rc.local
/usr/local/sersync/sersync2-d-r-o/usr/local/sersync/confxml.xml

First Test the rsync sync is ok
RSYNC-AV/TMP/YUM_SAVE_TX-2015-12-31-13-13X5ANWV.YUMTX 192.168.1.106::webbak

4, script monitoring Sersync
Because sometimes the Sersync script will automatically turn off, so you need to write a script automatically to detect the existence of the process, does not exist on the start, the script content is as follows:
vi/root/check_sersync.sh
#!/bin/bash
#Purpose: Check Sersync Whether it is alive
#Author: Steven
Sersync= "/usr/local/sersync/sersync2"
Conf_file= "/usr/local/sersync/confxml.xml"
status=$ (PS aux |grep ' sersync2 ' |grep-v ' grep ' |wc-l)
If [$STATUS-eq 0];
Then
$SERSYNC-D-r-o $CONF _file &
Else
Exit 0;
Fi

After the script is written, add it to the scheduled task.
Crontab-e
