rsync有关的配置
Rsync基本配置
基于本地rsync同步:
[root@localhost ~]# mkdir /todir
[root@localhost ~]# rsync -a /boot /todir/
[root@localhost ~]# ls /todir/
boot
[root@localhost ~]# rm -rf /todir/*
[root@localhost ~]# ls /todir/
[root@localhost ~]# rsync -a /boot/ /todir/
[root@localhost ~]# ls /todir/
config-2.6.18-348.el5 symvers-2.6.18-348.el5.gz
grub System.map-2.6.18-348.el5
initrd-2.6.18-348.el5.img vmlinuz-2.6.18-348.el5
lost+found
[root@localhost boot]# rsync -av /boot/ /todir/ --delete
删除目标有而源没有的文件（好像不对目录检查）
[root@dns1 todir]# mkdir /fromssh
[root@dns1 todir]# cd /
[root@dns1 /]# rsync -az [email protected]:/boot/ /fromssh/
下行要对目录有读的权限
The authenticity of host '192.168.150.110 (192.168.150.110)' can't be established.
RSA key fingerprint is 78:f9:23:4e:9d:a9:90:4c:c6:21:5e:60:44:22:d9:91.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.150.110' (RSA) to the list of known hosts.
[email protected]'s password:
[root@dns1 /]# ls /fromssh/
config-2.6.18-371.el5 lost+found vmlinuz-2.6.18-371.el5
grub symvers-2.6.18-371.el5.gz
initrd-2.6.18-371.el5.img System.map-2.6.18-371.el5
[root@dns1 /]# rsync -az /etc [email protected]:/tmp/
上行要对目录有写入的权限
基于RSYNC服务
[root@localhost ~]# rpm -q rsync
rsync-3.0.6-4.el5_7.1
[root@localhost ~]# cat /etc/rsyncd_users.db
ruser:pwd@123
[root@localhost ~]# chmod 600 /etc/rsyncd_users.db
加权限安全，和ftp一样的匿名用户一样，不可对/修改否则拒绝访问
[root@localhost ~]# cat /etc/rsyncd.conf
uid = nobody
gid = nobody
use chroot = yes
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
[tools]
path = /usr/src
read only = yes
dont compress =*.gz *.bz2 *.tgz *.zip
auth users = ruser
secrets file = /etc/rsyncd_users.db
[root@localhost ~]# chkconfig rsync on
[root@localhost ~]# service xinetd restart
[root@localhost ~]# netstat -ln | grep :873
tcp 0 0 0.0.0.0:873 0.0.0.0:* LISTEN
客户端：
[root@test1 ~]# rsync [email protected]::tools
Password:
drwxr-xr-x 4096 2014/06/24 20:54:13 .
drwxr-xr-x 4096 2009/10/01 22:58:39 debug

drwxr-xr-x 4096 2014/06/24 20:54:13 redhat
[root@test1 ~]# mkdir -p /data/fromrsync
[root@test1 ~]# rsync -avz --delete [email protected]::tools /data/fromrsync/
出错的原因
# iptables -L
# getenforce
# chmod 600 /etc/rsyncd_users.db
# service xinetd restart
# netstat -ln | grep :873
# /etc/xinetd.d/rsync
disable = yes
扩展实验： 实验目的是在目标主机修改时，本地实时备份
配置远程的备份目标主机
[root@node2 ~]# yum -y install httpd
[root@node2 ~]# mkdir -p /webbak/www1
[root@node2 ~]# cat /etc/exports
/webbak/www1 *(rw,no_root_squash)
[root@node2 ~]# service portmap restart
[root@node2 ~]# service nfs restart
[root@node2 ~]# chkconfig portmap on
[root@node2 ~]# chkconfig nfs on
配置本地的备份源主机
[root@node1 ~]# yum -y install gcc* httpd
[root@node1 ~]# tar -zxvf inotify-tools-3.14.tar.gz -C /usr/src/
[root@node1 ~]# cd /usr/src/inotify-tools-3.14/
[root@node1 inotify-tools-3.14]# ./configure
[root@node1 inotify-tools-3.14]# make
[root@node1 inotify-tools-3.14]# make install
[root@node1 inotify-tools-3.14]# service portmap restart
[root@node1 inotify-tools-3.14]# chkconfig portmap on
[root@node1 inotify-tools-3.14]# mkdir -p /data/nfsdir
[root@node1 inotify-tools-3.14]# grep nfs /etc/fstab
192.168.100.20:/webbak/www1 /data/nfsdir nfs defaults 0 0
[root@node1 inotify-tools-3.14]# mount -a
[root@node1 inotify-tools-3.14]# df -hT | grep nfs
nfs 7.6G 1.1G 6.1G 16% /data/nfsdir
[root@node1 ~]# cat /usr/bin/in_rsync.sh
#!/bin/bash

do
/usr/bin/rsync -aHvz --delete /var/www/html/ /data/nfsdir
done
[root@node1 ~]# chmod 700 /usr/bin/in_rsync.sh
[root@node1 ~]# echo "/usr/bin/in_rsync.sh" >> /etc/rc.local
[root@node1 ~]# /usr/bin/in_rsync.sh
