首先客戶端和服務端都需要安裝rsync軟件。
yum -y install rsync
----服務端配置-------
步驟1：
建立rsyncd.conf默認配置文件。touch /etc/rsyncd.conf
#Rsync server
#created by oldboy 15:04 2021-01-29
##rsyncd.conf start##
uid = rsync
gid = rsync
use chroot = no
max connections = 2000
timeout = 600
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log
ignore errors
read only = false
list = false
hosts allow = 192.168.3.0/24
hosts deny = 0.0.0.0/32
auth users = rsync_backup
secrets file = /etc/rsync.password
########################################
[backup]
comment = backup by oldboy 15:11 2021-01-29
path = /backup/
########################################
#[wwww]
#comment = www by oldboy 15:11 2021-01-29
#path = /data0/www/www/
########################################
#[bbs]
#comment = bbs by oldboy 15:11 2021-01-29
#path = /data0/www/bbs/
########################################
#[blog]
#comment = blog by oldboy 15:11 2021-01-29
#path = /data0/www/blog/
步驟2：
創建rsync用戶，及共享的目錄/backup
useradd rsync -s /sbin/nologin -M
id rsync
mkdir /backup
chown -R rsync /backup
步驟3：
創建密碼文件。
echo "rsync_backup:oldboy" >>/etc/rsync.password
chmod 600 /etc/rsync.password
步驟4：
rsync --deamon
netstat -lntup|grep rsync
ps -ef|grep rsync|grep -v grep
步驟5：加入開機自啓動
echo "rsync --daemon" >>/etc/rc.local
cat /etc/rc.local
----客戶端配置-------
rsync客戶端：
1、echo "oldboy" >>/etc/rsync.password
chmod 600 /etc/rsync.password
ls -l /etc/rsync.password
cat /etc/rsync.password
2、rsync
push(推)：
rsync [OPTION...] SRC... [USER@]HOST::DEST
rsync -avz /tmp/ [email protected]::backup --password-file=/etc/rsync.password
