samba服务器端提供共享服务，同时作为rsync客户端将数据实时备份到rsync服务器端
samba服务器端：
yum install samba
smb服务，nmb服务负责主机名解析
添加用户，需要提前创建linux用户
useradd –s /sbin/nologin smb1
smbpasswd –a smb1
smbpasswd smb1修改口令
smbpasswd –x smb1删除用户
pdbedit –L [-v] 查看用户列表
windows匿名访问
vim /etc/samba/smb.conf
[public]
map to guest = Bad User
共享文件夹配置下添加
public = yes
[pub]
comment = app
path = /data/bz2
valid user = smb1,@admins
writable = yes默认为no
write list = smb2 writable 为no时，只有smb2可写 +或@admins表示组
public = yes
Linux客户端
smbclient //ip/文件夹 –U user%pass
mount –o username=,password= //ip/文件夹 /mnt/smb
自动挂载
vim /etc/fstab
//ip/文件夹 /mnt/smb cifs username=,password= 0 0
或者//ip/文件夹 /mnt/smb cifs credentials=/etc/smbuser.txt 0 0
vim /etc/smbuser.txt
username=
password=
chmod 600 smbuser.txt
rsync服务器端
yum install rsync
vim /etc//etc/rsyncd.conf uid = root gid = root use chroot = no max connections = 0 ignore errors exclude = lost+found/ log file = /var/log/rsyncd.log pid file = /var/run/rsyncd.pid lock file = /var/run/rsyncd.lock reverse lookup = no hosts allow = 192.168.35.0/24 [backup] path = /data/share comment = backup read only = no auth users = rsyncuser secrets file = /etc/rsync.pass
echo "rsyncuser:centos" > /etc/rsync.pass
chmod 600 /etc/rsync.pass
rsync --daemon 可加入/etc/rc.d/rc.local实现开机启动
rsync客户端：
yum install inotify-tools rsync
echo "centos" > /etc/rsync.pass
chmod 600 /etc/rsync.pass
将本地share文件夹下文件(最后要加/不然会把文件夹一起同步)同步到rsync服务器backup，真实路径/data/share
测试rsync -avz --password-file=/etc/rsync.pass /data/share/ [email protected]::backup
脚本
vim inotify.sh #!/bin/bash SRC='/data/share/' DEST='[email protected]::backup' inotifywait -mrq --timefmt '%Y-%m-%d %H:%M' --format '%T %w %f' -e create,delete,moved_to,close_write,attrib ${SRC}\ |while read DATE TIME DIR FILE;do FILEPATH=${DIR}${FILE} rsync -az --delete --password-file=/etc/rsync.pass $SRC $DEST && echo "At ${TIME} on ${DATE}, file $FILEPATH was backuped up via rsync" >> /var/log/changelist.log done
