服務端安裝與配置192.168.2.10

1. 安裝rsync

[root@localhost ~]# yum -y install rsync

2. 建立密碼認證文件,并且賦權限

[root@localhost ~]# cd /etc/
[root@localhost etc]# vi rsyncd.password
wbc@wodata
[root@localhost etc]# chmod 600 rsyncd.password

3 修改配置文件

[root@localhost ~]# cd /etc/
[root@localhost etc]# vi rsyncd.conf 
uid = root
gid = root
use chroot = no
max connections = 3
timeout = 800
pid file = /var/run/rsyncd.pid
lockfile = /var/run/rsyncd.lock
log file = /var/log/rsyncd.log

[uploads]
path = /home/wbc/webroot/ROOT/upload
ignore errors = yes
host allow = 192.168.0.0/255.255.0.0
#hosts deny = *
read only = no
write only = no
list = yes
auth users = wbc
secrets file = /etc/rsyncd.password

4. 安裝inotify-tools，安裝在etc下

需要有編譯環境 yum install make gcc gcc-c++

[root@localhost ~]# cd /etc/
[root@localhost etc]# wget http://cloud.github.com/downloads/rvoicilas/inotify-tools/inotify-tools-3.14.tar.gz
[root@localhost etc]# tar zxvf inotify-tools-3.14.tar.gz 
[root@localhost etc]# rm -rf inotify-tools-3.14.tar.gz
[root@localhost ~]# cd /etc/inotify-tools-3.14/
[root@localhost inotify-tools-3.14]# ./configure --prefix=/etc/inotify
[root@localhost inotify-tools-3.14]# make
[root@localhost inotify-tools-3.14]# make install

5. 創建rsync復制腳本

將服務端的/home/wbc/webapps/ROOT/upload/同步到備份端的/home/wbc/webapps/ROOT/uploads/，進行冗余備份，不做刪除同步

[root@localhost etc]# vi rs-upload.sh
#!/bin/bash

src='/home/wbc/webapps/ROOT/upload/'
passwordfile='/etc/rsyncd.password'
user='wbc'
host0='192.168.2.11'
rsync_module='uploads'

if [ ! -d "${src}" ]; then
    mkdir -p ${src}
fi

/etc/inotify/bin/inotifywait -mrq --timefmt '%Y%m%d %H%M%S' --format '%T %w %f' -e modify,delete,create,attrib ${src} | while read DATE TIME DIR file

do
    /usr/bin/rsync -vzrtopg --progress ${src} ${user}@${host0}::${rsync_module} --password-file=${passwordfile}

    echo "${file} was rsynced at ${DATE}_${TIME} in ${DIR}" >> /var/log/rsync-upload.log 2>&1
done

6. 后臺執行腳本

[root@localhost etc]# sh rs-upload.sh &

如果有報錯
inotifywait: error while loading shared libraries: libinotifytools.so.0: cannot open shared object file: No such file or directory

解決方法：
32位系統：ln -s /etc/inotify/lib/libinotifytools.so.0 /usr/lib/libinotifytools.so.0
64位系統：ln -s /etc/inotify/lib/libinotifytools.so.0 /usr/lib64/libinotifytools.so.0

備份端安裝與配置192.168.2.11

1. 安裝rsync

[root@localhost ~]# yum -y install rsync

2. 建立密碼認證文件,并且賦權限

[root@localhost ~]# cd /etc/
[root@localhost etc]# vi rsyncd.password
wbc@wodata
[root@localhost etc]# chmod 600 rsyncd.password

3 修改配置文件

[root@localhost ~]# cd /etc/
[root@localhost etc]# vi rsyncd.conf 
uid = root
gid = root
use chroot = no
max connections = 3
timeout = 800
pid file = /var/run/rsyncd.pid
lockfile = /var/run/rsyncd.lock
log file = /var/log/rsyncd.log

[uploads]
path = /home/wbc/webapps/uploads
ignore errors = yes
host allow = 192.168.0.0/255.255.0.0
#hosts deny = *
read only = no
write only = no
list = yes
auth users = wbc
secrets file = /etc/rsyncd.password

4. 新增自定義服務文件

[root@localhost etc]# vi /init.d/rsync
#!/bin/sh
#whoami
#root
#chkconfig: 345 51 49
#description: starts the rsync deamons
#

case "$1" in
start)
echo "Starting Rsync ..."
rsync --daemon --config=/etc/rsyncd.conf
;;
stop)
echo "Stop Rsync ..."
pkill rsync > /dev/null 2>/dev/null
;;
restart)
echo "Restart Rsync ..."
$0 stop
$0 start
;;
*)
echo "Usage: $1 {start|stop|restart}"
;;
esac
exit 0

5. 啟動服務

[root@localhost etc]# cd /init.d
[root@localhost etc]# vi rsync
#!/bin/sh
#whoami
#root
#chkconfig: 345 51 49
#description: starts the rsync deamons
#

case "$1" in
start)
echo "Starting Rsync ..."
rsync --daemon --config=/etc/rsyncd.conf
;;
stop)
echo "Stop Rsync ..."
pkill rsync > /dev/null 2>/dev/null
;;
restart)
echo "Restart Rsync ..."
$0 stop
$0 start
;;
*)
echo "Usage: $1 {start|stop|restart}"
;;
esac
exit 0

6. 為自定義服務賦權限

[root@localhost init.d]# chmod +x rsync 

7. 啟動服務

[root@localhost init.d]# service rsync start

目前為止已經安裝配置好了

1. 在服務端測試

[root@localhost upload]# mkdir test

正常情況會輸出以下信息
[root@localhost upload]# sending incremental file list
./
test/

sent 107 bytes  received 19 bytes  252.00 bytes/sec
total size is 0  speedup is 0.00

2. 在備份端做檢查

查看該目錄下是否有test文件夾
[root@localhost ~]# ll /home/wbc/webapps/uploads
