Realize inotify and Rsync real-time backup

Realization inotify coordination rsync Real time backup

（ One ）： The daemon mode of the server and the daemon mode of the client rsync To configure

1. Configure server rysnc     vi /etc/rsyncd.conf Contents of Li uid = rsync      gid = rsync      use chroot = no      max connections = 200      timeout = 100      pid file = /var/run/rsyncd.pid      lock file = /var/run/rsync.lock      log file  = /var/log/rsyncd.log      [backup]      path = /backup/      ignore errors      read only = false      list =  false      hosts allow = 199.101.117.0/24      hosts deny = 0.0.0.0/32      auth users = rsync_backup      secrets file = /etc/rsync.password

## If in windows Edit or copy the code to linux You'd better use this command to handle the following Dos2unix /etc/rsyncd.conf [[email protected] backup]#mkdir /backup [[email protected] backup]#useradd rsync -s /bin/nologin –M                           

## Create a new account （ And configuration files uid-gid Corresponding , This account attribute cannot be logged in and has no directory ） [[email protected] backup]#chown -R rsync.rsync /oldboy                               

[[email protected] backup]#echo “rsync_backup:oldboy”> /etc/rsync.password 

##rsync_backup Is a virtual account , At that time, the client connection will use this account and password oldboy. [[email protected] backup]#chmod 600 /etc/rsyncd.password                                  ### Set it so that no one else can see , Because there is a password in it [[email protected] backup]#rsync --daemon 

# Start the process

2. To the client configuration ： Just these two steps [[email protected] ~]#echo “oldboy”>/etc/rsync.password                       

# This path has nothing to do with the server path , Just for the sake of standardization , The password must be the same as the service [[email protected] ~]#chmod 600 /etc/rsync.password

（ Two ）： Client's inotify Deploy

[[email protected] ~]#wget  http://github.com/downloads/rvoicilas/inotify-tools/inotify-tools-3.14.tar.gz [[email protected] ~]# ll /proc/sys/fs/inotify/ total 0 -rw-r--r-- 1 root root 0 Jan 21 00:34 max_queued_events -rw-r--r-- 1 root root 0 Jan 21 00:34 max_user_instances -rw-r--r-- 1 root root 0 Jan 21 00:34 max_user_watches #### Check the order ; You can see that these three descriptions support inotify, Execute the following command （ It can be copied and executed in batch ） [[email protected] ~]#tar zxf inotify-tools-3.14.tar.gz [[email protected] ~]#cd inotify-tools-3.14 [[email protected] ~]#./configure --prefix=/usr/local/inotify-tools-3.14 [[email protected] ~]#make && make install [[email protected] ~]#ln -s /usr/local/inotify-tools-3.14 /usr/local/inotify ##vps Need to install make gcc gcc++,/usr/local/inotify/bin/inotifywait --help There are many parameters in , But just remember create and delete Parameters , Used to listen for events to trigger inotify

Write a script inotify as follows ： [[email protected] ~]#vi realtime.sh

#!/bin/bash host01=199.101.117.34 src=/backup dst=backup user=rsync_backup rsync_passfile=/etc/rsync.password inotify_home=/usr/local/inotify

if [ ! -e "$src" ] \ || [ ! -e "${rsync_passfile}" ] \ || [ ! -e "${inotify_home}/bin/inotifywait" ] \ || [ ! -e "/usr/bin/rsync" ]; then echo "Check File and Folder" exit 0 fi

${inotify_home}/bin/inotifywait -mrq --timefmt '%d%m%y %H:%M' --format '%T %w%f' -e close_write,delete,create,attrib $src \ | while read file   do     cd $src && rsync -aruz -R --delete ./ --timeout=100 [email protected]$host01::$dst --password-file=${rsync_passfile} >/dev/null 2>&1     done exit 0 ## That's the script [[email protected] ~]#nohup ./realtime.sh &  # Start the background listening script stay /backup Test under Directory touch {1..100}, On the server side /backup This will be synchronized soon 100 File , success ！ If it is not successful, you need to manually check each command , of rsync Server configuration of , See Rsync The simple application and configuration of
