3.rsync服务端配置详解(web01“ip 10.160.1.15”)
(1)rsync配置文件详解
cat /etc/rsyncd.conf
rsync_config_______________start
uid = rsync
gid = rsync
use chroot = no
fake super = yes
max connections = 200
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 = 10.160.1.0/24
hosts deny = 0.0.0.0/32
auth users = rsync_backup
secrets file = /etc/rsync.password
[date]
comment = welcome to oldboyedu backup!
path = /date/
(2)创建rsync目录和用户
mkdir /date
useradd rsync
chown -R rsync:rsync
(3)配置rsync密码文件
cat /etc/rsync.password
rsync_backup:oldboy
chmod 600 /etc/rsync.password

4.配置rsync客户端(web02)
配置rsync密码认证文件
方法一:
cat /etc/rsync.password
oldboy
chmod 600 /etc/rsync.password
方法二:
echo ' export RSYNC_PASSWORD=oldboy' >>/etc/bashrc
. /etc/bashrc

5.生产案例
每天晚上00点整在web服务器A(web02)上打包备份网站程序目录并通过rsync命令推送到服务器B(web01)上备份保留(备份思路可以是先在本地按日期大包,然后再利用rsync推到备份服务器上)
web01脚本
cat /scripts/rsync.sh

!/bin/bash

backup conf and /etc/hosts

mkdir /date/html_(date +%F)/html_$(date +%F -d "-1day").tar.gz hosts

md5

mkdir /date/md5sum_(date +%F)/hosts_md5_$(date +%F)

rsync

rsync -avz /date/ [email protected]::date --password-file=/etc/rsync.password
web01 定时任务

  • 0 * * * /usr/bin/sh /scripts/rsync.sh &>/dev/null
