one。 The server (the host that needs to be synchronized) 1. Install rsync yum install-y rsync 2. Configuration, add profile / etc/rsyncd.conf

[global]

Uid = root

Gid = root

Use chroot = no

Max connections = 10

List = yes

Pid file = / var/run/rsyncd.pid

Lock file = / var/run/rsyncd.lock

Log file = / var/log/rsyncd.log

Hosts allow = 192.168.217.130 / / whitelist, IP address of machines allowed to synchronize

[data] / / data directory alias, which is required for synchronization

Path = / usr/local/src / / the synchronization directory corresponding to the alias

Ignore errors

Read only = yes

Auth users = vicxiang / / user name used in synchronization

Secrets file = / etc/sery.pass / / account password configuration file used during synchronization

3. Configuration, add profile / etc/sery.pass

Vicxiang:123456

Modify file permissions chmod 600 / etc/sery.pass 4. Start the rsync service rsync-- daemon-- config=/etc/rsyncd.conf 5. Firewall setting, the port needs to be open to tcp 873II. Client (the destination machine to which the files are synchronized) 1. Configure password file / etc/sery_client.pass

Modify file permissions chmod 600 / etc/sery_client.pass 2. Synchronization command rsync-avr-P vicxiang@192.168.217.128::data / usr/local/src/-- password-file=/etc/sery_client.pass where vicxiang is the user name used during synchronization; 192.168.217.128 is the data directory alias configured by the server IP; data; / usr/local/src/ is the directory synchronized to the local machine / etc/sery_client.pass is the configuration password file III. Write script rsync.sh with crontab timing synchronization

Log_file=rsync.log

Function sync () {

Ip=$ {1}

Path=$ {2}

T=date +% Y%m%d-%H%M%S

Echo "${t} start to sync data from ${ip}..." > > ${log_file}

Rsync-avr-P vicxiang@$ {ip}:: data ${path}-password-file=/etc/sery_client.pass

Echo "done" > > ${log_file}

}

Sync ip path
