ubuntu系统自带rsync，首先配置/etc/default/rsync，启用daemon模式
修改/etc/rsyncd.conf配置文件
cat /etc/rsyncd.conf
# sample rsyncd.conf configuration file# GLOBAL OPTIONS#motd file=/etc/motd
log file=/var/log/rsyncd
# for pid file, do not use /var/run/rsync.pid if
# you are going to run rsync out of the init.d script.
# The init.d script does its own pid file handling,
# so omit the "pid file" line completely in that case.
pid file=/var/run/rsyncd.pid
syslog facility=daemon
#socket options=# MODULE OPTIONS[image_ftp]comment = public archive#comment名称自定义
path = /var/www/html#需要同步的目录
use chroot = no
#max connections=10
lock file = /var/lock/rsyncd
# the default for read only is yes...
read only = yes
list = yes
uid = root
gid = root
#exclude =
#exclude from =
#include =
#include from =
auth users = root #该用户需和客户端拉取用户保持一致,这里以root为例
secrets file = /etc/rsyncd.secrets #用户密码文件
strict modes = yes
hosts allow = 192.168.1.100 #允许拉取的客户端ip
#hosts deny =
ignore errors = yes
ignore nonreadable = yes
transfer logging = yes
log format = %t: host %h (%a) %o %f (%l bytes). Total %b bytes.
timeout = 600
refuse options = checksum dry-run
dont compress = *.gz *.tgz *.zip *.z *.rpm *.deb *.iso *.bz2 *.tbz
创建存放用户名和密码的文件
vim /etc/rsyncd.secrets
启动rsync服务
/etc/init.d/rsync start
赋予600权限
chmod 600 /etc/rsyncd.secrets
查询服务是否启动,注意防火墙需要开放873端口
在客户端上执行拉取命令，nohup+& 让服务保持在后台运行，防止中断
nohup rsync -avuz -e 'ssh -p 2222' root@192.168.1.100:/var/www/html /data &
nohup rsync -avuz -e 'ssh -p 2222' root@192.168.1.100:/var/www/html /data
ctrl + z 挂起
bg 将进程置于后台运行
jobs 查询后台运行任务
