rsync server:配置步骤
1、vi /etc/rsyncd.conf
#Rsync server
#created by lijianfeng 18:26 2017-9-24
#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 = true
hosts allow = 172.16.1.0/24
#hosts deny = 0.0.0.0/32
auth users = rsync_backup
secrets file = /etc/rsync.password
################################################
[backup]
comment = backup by lijianfeng 18:29 2017-09-24
path = /backup
2、创建rsync用户，共享目录/backup
useradd rsync -s /sbin/nologin -M
id rsync
mkdir /backup
chown -R rsync /backup/
3、创建密码文件
echo "rsync_backup:oldboy" >/etc/rsync.password
chmod 600 /etc/rsync.password
cat /etc/rsync.password
4、启动服务并加入开机自启动rsync --daemon
echo "rsync --daemon" >>/etc/rc.local
rsync --daemon
netstat -lntup|grep rsync
ps -ef|grep rsync|grep -v grep
5、关闭防火墙
/etc/init.d/iptables stop
ntpdate time.nist.gov
6、关闭SELINUX
rsync客户端配置
1、创建密码文件
echo "oldboy" >/etc/rsync.password
chmod 600 /etc/rsync.password
ls -l /etc/rsync.password
cat /etc/rsync.password
2、关闭防火墙,关闭SELINUX
/etc/init.d/iptables stop
ntpdate time.nist.gov
3、定时执行同步命令push:
备份脚本
mkdir /server/scripts -p
cd /server/scripts
vim rsync_client.sh
#!/bin/sh
path=/backup
dir="`ifconfig eth0|awk -F '[ :]+' 'NR==2 {print $4}'`_$(date +%F)"
mkdir $path/$dir -p &&\
/bin/cp /var/spool/cron/root $path/$dir/cron_root_$(date +%F) &&\
/bin/cp /etc/rc.local /$path/$dir/rc.local_$(date +%F)
rsync -az $path/ rsync_backup@172.16.1.5::backup --password-file=/etc/rsync.password
说明：全路径试运行脚本
/bin/sh /server/scripts/rsync_client.sh
定时任务每天19:00执行脚本rsync_client.sh
crontab -e
