Rsync Synchronization Service installation configuration and script usage

Rsync It is an application software under Unix/linux, it can keep multiple server data synchronization consistency, rsync will copy the whole content on the first synchronization, but only the modified files are transmitted the next time.

Rsync in the process of transmitting data, it is possible to compress and Unzip operation, so you can use less bandwidth. can easily do to keep the original file permissions, time, soft and hard links. Rsync has two synchronization methods, one based on SSH synchronization does not need to configure, a need for their own key synchronization needs to file configuration. The following is the way I use my own secret key: The majority of enterprises

2. Rsync installation

   Experiment two virtual machines: Server 192.168.2.222, client 192.168.2.183

   Easy to experiment, I use Yum installation method here: Yum Install rsync-y

4. I am here to customize the rsync configuration directory mkdir/home/lijq/.rsync/-p; Create configuration file Add the following VI rsyncd.conf;

   UID = nobody
   GID = Nobody
   Use chroot = no
   Max connections = 30
   PID file =/home/lijq/.rsync/rsyncd.pid
   Lock file =/home/lijq/.rsync/rsyncd.lock
   Log file =/home/lijq/.rsync/rsyncd.log
   Transfer logging = yes
   Log format =%t%a%m%f%b
   Syslog facility = Local3
   Timeout = 300
   [Test1]
   Read Only = no
   Path =/data/www
   Comment = www
   Auth users = Test
   Secrets file =/home/lijq/.rsync/rsync.pas
   Hosts allow = 192.168.2.183

6. Cd/home/lijq/.rsync; Create Rsync.pas key file test:123456 and give permissions chmod 666 Rsync.pas

8. Then start the service, I am here to customize the configuration path and port all start commands for the following:

   /usr/bin/rsync--daemon--config=/home/lijq/.rsync/rsyncd.conf--port 7001

   Using Ps-ef | grep rsync to view service startup conditions

10. Client configuration, only need to create Rsync.pas password file content 123456 under cd/home/lijq/.rsync/and give 600 permissions

12. Then create the server-side synchronization directory, the above configuration file is defined by the/data/www

14. Client execution Rsync-ap--delete [email protected]:: TEST1/ROOT/LIJQ--port=7001--password-file=/home/lijq/.rsy Nc/rsync.pas

16. The above command is the contents of the client Synchronization server file,/ROOT/LIJQ for the client directory can be defined by itself, the port is my own definition, test1 is my service-side definition of the synchronization module name

18. If error @error:auth failed on module test1 Please check the key profile, if error: rsync:failed to connect to 192.168.2.222:no the route to host (113) Please check Firewalls and selinux, bloggers suffer

20. After the synchronization command executes, it is found that the/data/www/files on the server are synchronized to the client/ROOT/LIJQ below, and the done

Two. The above client performs the command synchronization is the server directory file synchronization to the client to the equivalent of backup, and many enterprises are from the client to update the data to the service side therefore: You can execute the following command on the client.

/usr/bin/rsync-avzp--progress--delete--password-file=rsyncd1.pas--port=7001/root/lijq/ [email protected] :: Test1 Rsyncd1.pas is a key file that I created in the current directory, or it can be written as the previous path.

If the error is rsync Error:some files/attrs were not transferred (see previous errors) (code) at MAIN.C (1039) [sender=3.0.6] Check the service End Directory Permissions other users should have write permission Oh, done

Script Implementation synchronization: Here the script is the client data synchronization to the server side, the other can be defined by themselves:

#!/bin/bash#use for:sh 33.sh test serversysuser=testexport mokuai=test1export port=7001src_dir=/root/lijq/serverip= 192.168.2.222serverno=$1case "$" intest) echo ${rsyncsource%/*};; Server)/usr/bin/rsync-avzp--progress--delete--password-file=rsyncd1.pas--port=${port $SRC _dir [email protected]$ ServerIP:: $MOKUAI;; Esac

Done
