rsync+inotify一键安装脚本

一、环境描述

server：192.168.122.54

client：192.168.122.55，192.168.122.56

同步目录：/data/html

server端有任何数据更新，即将同步到client端，实时同步

二、采用方法：rsync+inotify

三、关于inotify原理，请参考https://www.ibm.com/developerworks/cn/linux/l-inotify/

四、操作过程

4.1服务端脚本

#!/bin/bash

yum install rsync -y
mkdir -p /data/html #如果要同步的不是此目录，可以根据实际需要添加目录
#wget http://cloud.github.com/downloads/rvoicilas/inotify-tools/inotify-tools-3.14.tar.gz tar xzvf inotify-tools-3.14.tar.gz
cd inotify-tools-3.14
./configure
make
make install

#cponfigure inotify

cat >>/home/rsync.sh << EOF
#!/bin/bash
src=/data/html/   #同步的源目录

des=www
host="192.168.122.55 192.168.122.56"
/usr/local/bin/inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f' -e modify,delete,create,attrib \$src | while read files
do
for hostip in \$host
do
rsync -vzrtopg --delete --progress --password-file=/etc/rsyncd.secrets \$src root@\$hostip::\$des
done
echo "\${files} was rsynced" >>/tmp/rsync.log 2>&1
done
EOF

#confiugre secret
cat >> /etc/rsyncd.secrets << EOF
123456
root:123456
EOF
chmod 0600 /etc/rsyncd.secrets

#setting running onboot
echo "nohup /bin/bash /home/rsync.sh &" >> /etc/rc.local
nohup /bin/bash /home/rsync.sh &

4.2 客户端脚本

#!/bin/bash

yum install rsync -y
mkdir -p /data/html

#configure rsyncd daemon
cat >> /etc/rsyncd.conf  << EOF
uid = root
gid = root
use chroot = no
max connections = 5
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log

[www]
path=/data/html/
comment = update
ignore errors
read only = no
list = no
hosts allow = 192.168.122.0/24
auth users = root
uid = root
gid = root
secrets file = /etc/rsyncd.secrets
EOF

#configure secret
cat >> /etc/rsyncd.secrets << EOF
123456
root:123456
EOF
chmod 0600 /etc/rsyncd.secrets
echo "rsync --daemon" >> /etc/rc.local
rsync --daemon

五、测试过程。

略过测试过程，大家可以自己测试同步效果。

六、附一键安装包

svn钩子自动更新post-commit
for dir in $(svnlook dirs-changed /var/svn/web/)
do
svn update -N /opt/nginx/web/$dir --username "admin" --password "admin"
done
