CentOS服务器网络数据实时同步之 inotify + rsync

实例：

假设web01与web02是公司的网站，我们在内容发布服务器中添加数据，inotify检测到有数据更新通过rsync实时传输到web01与web02。

一、web配置(web01与web02配置几乎一致，留意红色部分)

# vi /etc/rsyncd.conf

# filename:/etc/rsyncd.conf

uid = nobody
gid = nobody

use chroot = no
max connections = 10
# set password
strict modes = yes

pid file = /var/run/rsyncd.pid
lock file = /var/run/rsyncd.lock
log file = /var/log/rsyncd.log

[web_01]
path = /var/www/html
comment = web dir
ignore errors
read only = no
write only = no
hosts allow = 172.16.10.0/255.255.255.0
hosts deny = *
list = false
auth = backup
secrets file = /etc/rsyncd.auth

# echo backup:backup>/etc/rsyncd.auth

# chmod 600 /etc/rsyncd.auth

二、内容发布服务器配置

//安装inotify-tool # tar zxvf inotify-tools-3.14.tar.gz # cd inotify-tools-3.14 # ./configure;make;make install //建立rsync验证文件 # echo backup:backup>/etc/rsyncd.auth # chmod 600 /etc/rsyncd.auth

 [root@10.1 ~]# vi inotify_rsync.sh #!/bin/bash # This rsync script based on inotify. export PATH=/bin:/usr/bin:/usr/local/bin src=/var/www/html/ dst=/var/www/html/ client1=172.16.10.101 client2=172.16.10.102 user=backup #password file must not be other-accessible. Passfiles=/etc/rsyncd.auth #Wait for change inotifywait -mrq --timefmt '%d-%m-%y %H:%M' --format '%T %w %fi %e' --event modify,delete,create,attrib $src|while read files do rsync -vzrtopg --progress --delete --password-file=$Passfiles $src $user@$client1::$dst rsync -vzrtopg --progress --delete --password-file=$Passfiles $src $user@$client2::$dst echo "${files} was rsynced" >> /var/log/inotify_web 2>&1 done

后台运行以上shell脚本，并在内容发布服务器上进行文件修改等操作
