inotify+rsync实时同步服务部署

环境：服务端 192.168.6.30（安装 rsync） /data/share

　　：客户端 192.168.6.38（安装 inotufy+rsync）/nfsbackup

主流程：https://www.cnblogs.com/clsn/p/7707822.html#auto_id_28

客户端安装 inotify

下面开始安装inotify-tools
[root@static-img ~]# yum install make gcc gcc-c++ #安装编译工具
[root@static-img ~]# cd /usr/local/src
[root@static-img src]# wget http://github.com/downloads/rvoicilas/inotify-tools/inotify-tools-3.14.tar.gz
[root@static-img src]# tar zxvf inotify-tools-3.14.tar.gz
[root@static-img src]# cd inotify-tools-3.14
[root@static-img inotify-tools-3.14]# ./configure --prefix=/usr/local/inotify
[root@static-img inotify-tools-3.14]# make && make install

发现已经成功安装inotify-tools了
[root@static-img inotify-tools-3.14]# ll -d /usr/local/inotify/
drwxr-xr-x 6 root root 4096 Oct 26 12:01 /usr/local/inotify/

设置系统环境变量
[root@static-img ~]# vim /etc/profile
......
export PATH=$PATH:/usr/local/inotify/bin
[root@static-img ~]# source /etc/profile

添加库文件
[root@static-img ~]# vim /etc/ld.so.conf
/usr/local/inotify/lib
[root@static-img ~]# ldconfig

修改inotify默认参数（inotify默认内核参数值太小）
查看系统默认参数值
[root@static-img ~]# sysctl -a | grep max_queued_events
fs.inotify.max_queued_events = 16384
[root@static-img ~]# sysctl -a | grep max_user_watches
fs.inotify.max_user_watches = 8192
[root@static-img ~]# sysctl -a | grep max_user_instances
fs.inotify.max_user_instances = 128

修改参数：
[root@static-img ~]# sysctl -w fs.inotify.max_queued_events="99999999"
[root@static-img ~]# sysctl -w fs.inotify.max_user_watches="99999999"
[root@static-img ~]# sysctl -w fs.inotify.max_user_instances="65535"

脚本

#!/bin/bash
Path=/data/share
backup_Server=192.168.6.30
/usr/local/inotify/bin/inotifywait -mrq --format '%w%f' -e create,close_write,delete /data/share  | while read line  
do
    if [ -f $line ];then
        rsync -az $line --delete rsync_backup@$backup_Server::nfsbackup --password-file=/etc/rsync.password
    else
        cd $Path &&
        rsync -az ./ --delete rsync_backup@$backup_Server::nfsbackup --password-file=/etc/rsync.password
    fi
done
