为了满足需要，之前的rsync定时推送服务，无法满足现实需要，在次更新网站架构
环境介绍：
网站Nginx集群搭建的，因为网站的数内容时常更新,但是一台一台的更新数据非常消耗时间。因此采用rsync+inotify，将数据实时的推送到集群主机上去。
远程网站IP：172.16.100.99 /usr/html
远程网站IP：172.16.100.97 /usr/html
本地推送IP：172.16.100.98 /web/data
环境：
RedHat5.9
rsync-3.1.1.tar.gz
inotify-tools-3.14.tar.gz
远程端IP99安装：
1.编译安装rsync-3.1.1.tar.gz
tar zxvf rsync-3.1.1.tar.gz
cd rsync-3.1.1
./configre
make
make install
2.编写rsyncd.conf配置文件
uid = nobody
gid = nobody
max connections = 10
use chroot = no
strict mode = no
pid file = /var/run/rsyncd.pid
lock file = /var/lock/rsync.lock
log file = /var/log/rsyncd.log
[web99]
path = /usr/html
comment = Nginx‘s page comment
read only = no
write only = no
ignore errors
uid = root
gid = root
host deny = *
host allow = 172.16.100.98
list = false
auth users = backup99
secrets file = /etc/server.pass
3.编写可访问推送端主机的密码文件
vi /etc/server.pass
backup99:123456
4.更改密码文件权限
chmod 600 /etc/server.pass
远程端IP97安装：
1.编译安装rsync-3.1.1.tar.gz
tar zxvf rsync-3.1.1.tar.gz
cd rsync-3.1.1
./configre
make
make install
2.编写rsyncd.conf配置文件
uid = nobody
gid = nobody
max connections = 10
use chroot = no
strict mode = no
pid file = /var/run/rsyncd.pid
lock file = /var/lock/rsync.lock
log file = /var/log/rsyncd.log
[web97]
path = /usr/html
comment = Nginx‘s page comment
read only = no
write only = no
ignore errors
uid = root
gid = root
host deny = *
host allow = 172.16.100.98
list = false
auth users = backup97
secrets file = /etc/server.pass
3.编写可访问推送端主机的密码文件
vi /etc/server.pass
backup97:123456
4.更改密码文件权限
chmod 600 /etc/server.pass
远程端IP98安装：
1.编译安装rsync-3.1.1.tar.gz
tar zxvf rsync-3.1.1.tar.gz
cd rsync-3.1.1
./configre
make
make install
2.编译安装inotify-tools-3.14.tar.gz
tar zxvf inotify-tools-3.14.tar.gz
cd inotify-tools-3.14
./configure
make
make intall
3.编写inotify同步脚本
vi inotify-sync.sh
#!/bin/bash
host1=172.16.100.99
host2=172.16.100.97
src=/web/data/
dst1=web99
dst2=web97
#dst2=images
user1=backup99
user2=backup97
inotifywait -mrq --timefmt ‘%d/%m/%y %H:%M‘ --format ‘%T %w%f%e‘ -e modify,create,delete,attrib $src |while read files
do
rsync -vzrtopg --delete --progress --exclude "*access*" --exclude "*debug*" --password-file=/etc/server.pass $src $user1@$host1::$dst1
rsync -vzrtopg --delete --progress --exclude "*access*" --exclude "*debug*" --password-file=/etc/server.pass $src $user2@$host2::$dst2
echo "${files} was rsyncd" >> /var/log/rsync.log 2>&1
done
