Rsync+inotify-tools real-time synchronization steps

Rsync needs to be installed on the client and server side, some distributions of Linux systems are installed by default and available: Rpm-qa rsync for queries

One, server-side configuration (192.168.1.1):

1.

The default rsync is that there is no configuration file for users to set themselves

Create an Rsync profile: vim/etc/rsyncd.conf

uid = root            #运行rsync守护进程的用户gid   = root            #运行rsync守护进程的组use  chroot  = no       #不使用chrootmax  connections = 2  # Maximum number of connections is strict modes = yes    #是否检查口令文件的权限port  = 873             #默认的端口号 # These are the files that are automatically generated after you start the Rsync service, or you can manually specify the path #pid file = Storage of  /usr/local/rsyncd.pid            pid Files # Storage   #log of lock file = /usr/local/rsync/rsync.locl      lock file  file  = /usr/local/rsync/log/rsyncd.log   log file Storage #motd file = /usr/local/rsync/ rsyncd.motd     Welcome Information [zt]                       #模块参数, the client will specify the path = /123/               #需要做镜像的目录comment  = my name is zt    #此模块的注释ignore  errors            # Ignore some extraneous IO errors read only = no           # Read-only list = no                  #不在服务器上吧提供同步数据的目录显示auth  users = zt            #认证的用户名, regardless of the system user, no this column means anonymous access! This user name needs to be consistent with the user name in Rsync.pass secrets file = /etc/rsync.pass          #指定的密码认证文件hosts  allow = 192.168.1.226             #允许的主机hosts  DENY = 0.0.0.0/0       &Nbsp;         #禁止的主机 

2.

Create a certified password file

Vim/etc/rsync.pass #需与上诉配置文件当中指定的密码认证文件一样

ZT:PASSWD #格式是 Account: Password, create complete save exit

chmod 600/etc/rsync.pass: Need to specify permissions

3.

Modify the configuration of rsync in xinetd: Vim/etc/xinetd.d/rsync

Inside you can see disable = yes to turn rsync off, change the value to No to open

4.

There are two ways to start rsync:

Start with daemon: rsync--daemon

Start with XINETD Super process:/usr/rc.d/init.d/xinetd/reload: or start

Second, the configuration of the client (192.168.1.2)

To download rsync, build the Rsync profile touch/etc/rsyncd.conf, note that the contents of the configuration file are empty!

Establish the password file Vim/etc/rsync.pass, go in Add passwd, only need to add the source server password can be

chmod 600/etc/rsync.pass operation after starting service

Three

Two common synchronization command formats are described here:

Server download to Local: Rsync-avz--delete [email protected]::zt/local Directory

On the ground to the server: Rsycn-avz--password-file=/etc/rsync.pass/local directory/[email protected]::zt

If the appeal of the operation is not a problem also reported wrong, it is recommended that the two machines 873 services killed and then started in one!

Netstat-anpt|grep 873: After viewing port kill-9 port: Kill

Or a change is made to initiate the action of the appeal.

Run Chekconfig--list to view after startup

Four

Scheduled periodic scheduled backups

Crontab-e

* * * * * */usr/bin/rsync-az--delete--password-file=/etc/rsync.pass [email protected]::zt/local Directory

#分时日月周, you can set your own

Date View system time, date-r view time zone, date-s modify system time

I have already removed the rsync parameter, or the error, to solve
