使用三台服务器：系统：CentOS 6.8
192.168.8.169 开发服务器
192.168.8.167 线上服务器1192.168.8.168 线上服务器2
实现思路：在开发服务器上制定一个规则，即只要rsync.txt存在，线上服务器就开始进行文件同步，同步完删除该文件。
实现步骤：（1）安装Rsync。
1、Rsync简介： Rsync（remote synchronize）是一个远程数据同步工具，可通过LAN/WAN快速同步多台主机间的文件。Rsync使用所谓的“Rsync算法”来使本地和远 程两个主机之间的文件达到同步，这个算法只传送两个文件的不同部分，而不是每次都整份传送，因此速度相当快。
2、Rsync安装：wget https://download.samba.org/pub/rsync/rsync-3.1.3.tar.gztar -zxvf rsync-3.1.3.tar.gzcd rsync-3.1.3
./configure --prefix=/usr/local/rsyncmakemake install
第二步：安装inotify和inotify-tools
Centos 6和CentOS 7,已经默认安装了inotify，如果要查看是否安装,可以使用如下命令:
ll /proc/sys/fs/inotify
如果列出如下三项，则证明已经安装max_queued_events
max_user_instances
max_user_watches
第三步：安装inotify-tools工具。wget https://jaist.dl.sourceforge.net/project/inotify-tools/inotify-tools/3.13/inotify-tools-3.13.tar.gztar -zxvf inotify-tools-3.13.tar.gzcd inotify-tools-3.13./configuremake && make install
第四步：线上服务器的配置：touch /etc/rsyncd.confvim /etc/rsyncd.conf
输入以下内容：uid = nobodygid = nobodyuse chroot = nomax connections = 10strict mode = nopid file = /var/run/rsyncd.pidlock file = /var/run/rsync.locklog file = /usr/data/rsync/rsyncd.log
[source-code]path = /usr/local/nginx/html/hello/comment = this is a comment message ignore errorsread only = nowrite noly = nohosts allow = 192.168.8.169hosts deny = *list = falseuid = rootgid = rootauth users = rootsecrets file = /usr/local/rsync/conf/server.pass
[source-code-update]path = /usr/local/nginx/html/hello-update/comment = this is a comment message ignore errorsread only = nowrite noly = nohosts allow = 192.168.8.169hosts deny = *list = falseuid = rootgid = rootauth users = rootsecrets file = /usr/local/rsync/conf/server.pass
说明： source-code是源代码目录。 source-code-update 是控制是否更新的目录。
然后继续在线上服务器操作：因为nginx部署的web位置一样，cd /usr/local/nginx/html/mkdir -p hello/cd /usr/local/rsync（rsync的安装位置）mkdir -p conf/cd conftouch server.passvim server.passroot:123abc+-给密码文件设置访问权限：chmod 600 server.pass
第五步：然后对开发服务器进行配置：touch /etc/rsyncd.confvim /etc/rsyncd.conf
输入以下内容：uid = nobodygid = nobodyuse chroot = nomax connections = 10strict mode = nopid file = /var/run/rsyncd.pidlock file = /var/run/rsync.locklog file = /usr/data/rsync/rsyncd.log
[source-code]path = /usr/local/nginx/html/hello/comment = this is a comment message ignore errorsread only = nowrite noly = nohosts allow = 192.168.8.169,192.168.8.167hosts deny = *list = falseuid = rootgid = rootauth users = rootsecrets file = /usr/local/rsync/conf/server.pass
建立项目目录cd /usr/local/nginx/html/mkdir hellocd /usr/local/rsync（rsync的安装位置）mkdir -p conf/
然后还要建立一个密码文件'/usr/local/rsync/conf/server.pass' 由于1是客户端，因此密码没有前缀123abc+-给密码文件设置访问权限：chmod 600 server.pass
cp /usr/local/rsync/bin/rsync /usr/bin/ /usr/local/rsync/bin/rsync --daemon
sh datarsync.sh
第一次测试/usr/local/bin/inotifywait \-mrq --timefmt '%d/%m/%y' \--format '%T %w%f%e' \-e modify,delete,create,attrib \/usr/local/nginx/html/hello/index.html \结果：有改变时，有输出
第二次测试，输出到log：/usr/local/bin/inotifywait \-mrq --timefmt '%d/%m/%y' \--format '%T %w%f%e' \-e modify,delete,create,attrib \/usr/local/nginx/html/hello/ | while read files do echo "${files} was rsyncd" >>/tmp/rsync.log 2>&1done结果：日志中有信息
第三次测试：
#!/bin/bash
src=/usr/local/nginx/html/hello/user=roothost2=192.168.8.167$dst2=source-code/usr/local/bin/inotifywait \-mrq --timefmt '%d/%m/%y' \--format '%T %w%f%e' \-e modify,delete,create,attrib \/usr/local/nginx/html/hello/ | while read files do /usr/bin/rsync -vzrtopg --delete --progress --password-file=/usr/local/rsync/conf/server.pass $src $user@$host2::$dst2 echo "${files} was rsyncd" >>/tmp/rsync.log 2>&1done
/usr/bin/rsync -vzrtopg --progress --delete root@192.168.8.169::source-code/usr/local/nginx/html/hello/* /usr/local/nginx/html/hello/
使用/usr/local/bin/inotifywait命令报错：/usr/local/bin/inotifywait: error while loading shared libraries: libinotifytools.so.0: cannot open shared object file: No such file or directory
[root@db zzh]# ll /proc/sys/fs/inotify （如果有下列三项则支持inotifytools）total 0-rw-r--r-- 1 root root 0 Sep 20 16:52 max_queued_events-rw-r--r-- 1 root root 0 Sep 20 16:52 max_user_instances-rw-r--r-- 1 root root 0 Sep 20 16:52 max_user_watches
解决：ln -s /usr/local/lib/libinotifytools.so.0 /usr/lib64/libinotifytools.so.0
rsync -avzP root@192.168.8.169::source-code /data/test/

169开发环境
166负载均衡服务器167 web服务器1168 web服务器2
169 修改代码同步到167和168上。169作为rsync客户端，167和168作为rsync服务端，
服务端配置（即167和168的配置）：（1）服务安装yum install rsync xinetd（2）为 rsyncd 服务编辑配置文件，默认没有，需自己编辑vim /etc/rsyncd.conf写入以下内容：uid = rootgid = rootuse chroot = nomax connections = 5timeout = 600pid file = /var/run/rsyncd.pidlockfile = /var/run/rsyncd.locklog file = /var/log/rsyncd.log[web1]path = /usr/local/nginx/html/hello/ignore errors = yesread only = nowrite only = nohosts allow = 192.168.8.169hosts deny = *list = yesauth users = websecrets file = /etc/web.passwd（3）创建文件同步的目录,上面配置里的path，如果有就不用创建了mkdir /usr/local/nginx/html/hello/（4）创建配置中的密码文件，并增加权限：echo "web:123" > /etc/web.passwdchmod 600 /etc/web.passwd（5）重新启动service xinetd restart
客户端配置（即169）：（1）安装软件yum -y install rsync（2）创建web目录mkdir /usr/local/nginx/html/hello/（3）设置密码并设置权限echo "123"> /tmp/rsync.passwordchmod 600 /tmp/rsync.password
测试：rsync -avzP --delete --password-file=/tmp/rsync.password /usr/local/nginx/html/hello/ web@192.168.8.167::web1
数据实时同步环境：Rsync + Inotify-tools。wget https://jaist.dl.sourceforge.net/project/inotify-tools/inotify-tools/3.13/inotify-tools-3.13.tar.gztar -zxvf inotify-tools-3.13.tar.gzmkdir /usr/local/inotifycd inotify-tools-3.13./configure --prefix=/usr/local/inotify/make && make install

vim /etc/profile在末尾增加一行：export PATH=$PATH:/usr/local/inotify/bin使配置生效：source /etc/profile创建shell文件：vim /test.sh输入以下内容：#!/bin/bash
