1.安装rsync和xinetd

yum install rsync xinetd


2.配置xinetd:

vi /etc/xinetd.d/rsync

#disable = yes修改为

disable = no


3.启动xinetd服务:

service xinetd start


4,编辑rsyncd.conf配置文件:

[root@dx-it-twebs01 wuxiaoyu]# cat /etc/rsyncd.conf 

#motd file = /etc/rsyncd.motd

use chroot = yes

uid=root

gid=root

max connections = 2000

timeout = 600

pid file = /var/run/rsyncd.pid

lock file = /var/run/rsyncd.lock

log file = /var/log/rsync.log

ignore errors

read only = false

list = false

hosts allow = 192.168.0.0/24

hosts deny = *


[wikidata]

comment = wikidata

path = /data/store/

auth users = test

secrets file = /etc/rsync/test_rsyncd.secrets

[root@dx-it-twebs01 wuxiaoyu]# 


5,配置服务端秘钥

mkdir /etc/rsync

touch /etc/rsync/test_rsyncd.secrets  ##密码为test:123456789

chmod  600 /etc/rsync/test_rsyncd.secrets


6,配置客户端服务秘钥

touch secrets.txt

chown  test.test secrets.txt

chmod  600 secrets.txt 


7,测试传输wuxiaoyu这个目录到rsync的服务端

rsync -varz  mfs/wuxiaoyu   test@dx-it-twebs01.dx.test.com::wikidata --password-file secrets.txt


网上有很多教程使用xinet.d来启动rsync服务端。

不过也使用rsync自带的来启动服务端

如:rsync --daemon --config=/home/leyewen/etc/rsync/rsyncd.conf

这种方式是以守护进程的方式启动服务,但是守护进程方式启动的进程不能被daemontools管理,daemontools 管理nginx的时候,nginx.conf 必须关闭daemon, daemon off;

http://kavy.iteye.com/blog/2119978

如果daemontools想管理rsync,则需要再run脚本中以如下方式启动(--no-detach 这个参数)

exec rsync --daemon  --no-detach --config=/etc/rsyncd.conf >> /var/log/rsync.log  2>&1

同时此脚本要有执行权限,chmod +x run

#!/bin/bash
NUM=`ps -ef |grep -v grep | grep -c "rsync --daemon"`
if [ $NUM -lt 1 ]
then
    cd /opt/apps/rsync
    #ulimit -c unlimited
    exec rsync --daemon  --no-detach --config=/etc/rsyncd.conf >> /var/log/rsync.log  2>&1
    #exec setuidgid test /opt/apps/xxx_agent/xxx_agent > /dev/null 2>&1
fi

--no-detach 含义 

When running as a daemon, this option instructs rsync to not detach itself and become a background process. This option is required when running as a service on Cygwin, and may also be useful when rsync is supervised by a program such as daemontools or AIX's System Resource Controller--no-detach is also recommended when rsync is run under a debugger. This option has no effect if rsync is run from inetd or sshd.
