一、服务器端(守护进程):
1.1 配置rsyncd服务,并重启服务和开机自启动服务以及查看服务是否开启
1.1.1 先配置vim /etc/rsyncd.conf文件
##Rsync server
##created by oldboy 15:01 2009-6-5
##rsyncd.conf start##
fake super = yes
uid = rsync (uid指定rsync运行的用户,虚拟用户)
gid = rsync (gid指定rsync运行的用户,虚拟用户)
use chroot = no
max connections = 2000(最大连接数)
timeout = 600 (超时时间)
pid file = /var/run/rsyncd.pid(pid进程号)
lock file = /var/run/rsync.lock(锁文件,两个窗口同时运行yum)
log file = /var/log/rsyncd.log(日志,排错需要查看)
ignore errors
read only = false (关闭只读)
list = false
#hosts allow = 10.0.0.0/24(白名单)
#hosts deny = 0.0.0.0/32(deny拒绝)
auth users = rsync_backup(指定认证用户,虚拟不存在)
secrets file = /etc/rsync.password(密码文件)
#####################################

path = /data (指定共享目录)
#####################################
[backup](data模块一般与目录的名字相同)
comment = www by old0boy 14:18 2012-1-13
path = /backup (指定共享目录)
1.1.2 配置完 /etc/rsyncd.conf文件后,重启服务
systemctl restart rsyncd (重启服务)
systemctl enable rsyncd (开机自启动服务)
1.1.3 查看是否启动和开机自启动
[root@backup ~]# systemctl status rsyncd
● rsyncd.service - fast remote file copy program daemon
Loaded: loaded (/usr/lib/systemd/system/rsyncd.service; enabled; vendor preset: disabled)
Active: active (running) since Tue 2019-05-21 14:56:27 CST; 4h 36min ago
Main PID: 8891 (rsync)
CGroup: /system.slice/rsyncd.service
└─8891 /usr/bin/rsync --daemon --no-detach

May 21 14:56:27 backup systemd[1]: Started fast remote file copy program daemon.
[root@backup ~]# systemctl is-enabled rsyncd
enabled
1.1.4 查看进程与端口是都开启
root@backup ~]# ps -ef |grep rsync
root 9749 1 0 16:12 ? 00:00:00 /usr/bin/rsync --daemon --no-detach
root 9751 9490 0 16:13 pts/1 00:00:00 grep --color=auto rsync
[root@backup ~]# ss -lntup|grep rsync
tcp LISTEN 0 5 *:873 *:* users:(("rsync",pid=9749,fd=3))
tcp LISTEN 0 5 :::873 :::* users:(("rsync",pid=9749,fd=5))
1.2 创建虚拟用户rsync,创建backup块目录,并给backup目录修改成rsync用户主与用户组
1.2.1 创建rsync虚拟用户
[root@backup ~]# useradd -M -s /sbin/nologin rsync
1.2.2 创建backup块目录
[root@backup ~]# mkdir /backup
1.2.3给backup目录修改成rsync用户主与用户组
[root@backup ~]# chown rsync.rsync /backup
1.3 创建密码文件/etc/rsync.password,并写入密码,然后授权600的权限
1.3.1 创建rsync.password文件,并写入密码123456
[root@backup ~]# echo "rsync_backup:123456" >/etc/rsync.password
1.3.2 修改文件/etc/rsync.password的权限
[root@backup ~]# chmod 600 /etc/rsync.password
1.4 把/etc/hosts文件推到本地的backup块目录
[root@backup ~]# rsync -avz /etc/hosts rsync_backup@backup::backup
Password: (输入/etc/rsync.password里的密码)
sending incremental file list
hosts
sent 221 bytes received 49 bytes 108.00 bytes/sec
total size is 349 speedup is 1.29
二、客户端(守护进程):
2.1 创建密码文件/etc/rsync.password,并写入密码,然后授权600的权限
2.1.1创建rsync.password文件,并写入密码123456
[root@nfs01 ~]# echo "123456" >/etc/rsync.password
2.1.2 修改文件/etc/rsync.password的权限
[root@nfs01 ~]# chmod 600 /etc/rsync.password
2.2 需要输入密码式的推送(把/etc/hosts 推送到服务器端的块目录data):
[root@nfs01 /]# rsync -avz /etc/hosts rsync_backup@10.0.0.41::data
Password:
sending incremental file list
hosts
sent 89 bytes received 49 bytes 55.20 bytes/sec
total size is 349 speedup is 2.53
2.3 不需要输入密码式的推送(把/etc/hosts 推送到服务器端的块目录data):
[root@nfs01 /]# rsync -avz /etc/hosts rsync_backup@10.0.0.41::data --password-file=/etc/rsync.password
sending incremental file list
sent 48 bytes received 20 bytes 136.00 bytes/sec
total size is 349 speedup is 5.13
