centos7下rsync+inotify脚本实现文件同步，.NET CORE客户端文件更新后自动重启服务

源服务器IP：192.168.8.51

目标服务器IP：192.168.8.79

安装前源服务器及目标服务器均需关闭FIREWALLD\SELINUX防火墙

sestatus | grep status

systemctl disable firewalld.service

setenforce 0

一、源服务器安装

源服务器需要安装inotify－tools、rsync 服务，inotify脚本服务放置此主机上监控源文件目录变化：

安装inotify－tools

yum -y intsll inotify-tools

安装rsync并配置开机启动

yum -y intsll inotify-tools
systemctl enable --now rsyncd.service

密码配置文件rsync.pas 放置在/etc目录下，并修改权限为600

123456

chmod 600 /etc/rsync.pas

重启rsync服务

systemctl restart rsyncd

准备inotify_rsync.sh　脚本来监控源文件目录

#!/bin/bash
# chkconfig: 2345 10 90
# description: resind

SRC='/wwwroot/web/ma_tm_system/'
DEST='rsyncuser@192.168.8.79::backup'
rpm -q rsync &> /dev/null || yum -y install rsync
inotifywait -mrq --exclude=".*\.swp" --timefmt '%Y-%m-%d %H:%M:%S' --format '%T %w %f' -e create,delete,moved_to,close_write,attrib ${SRC} |while read DATE TIME DIR FILE;do
    FILEPATH=${DIR}${FILE}
    rsync -az --delete --password-file=/etc/rsync.pas $SRC $DEST && echo "At ${TIME} on ${DATE}, file $FILEPATH was backuped up via rsync" >> /var/log/changelist.log
 done

脚本放置在　/etc/init.d/下，并增加可执行权限,并配置开机启动。

chmod +x /etc/init.d/inotify_rsync.sh
chkconfig --add inotify_rsync.sh

二、目标服务器：192.168.8.79安装：

1、安装inotify－tools

yum -y intsll inotify-tools

2、安装rsync并配置开机启动

yum -y intsll inotify-tools
systemctl enable --now rsyncd.service

3、备份rsync原配置文件及密码文件，并用准备好的配置文件覆盖。

cp /etc/rsyncd.conf  /etc/rsyncd.conf.bak

准备好的　rsyncd.conf　配置文件

# /etc/rsyncd: configuration file for rsync daemon mode

# See rsyncd.conf man page for more options.

# configuration example:

# uid = nobody
# gid = nobody
# use chroot = yes
# max connections = 4
# pid file = /var/run/rsyncd.pid
# exclude = lost+found/
# transfer logging = yes
# timeout = 900
# ignore nonreadable = yes
# dont compress   = *.gz *.tgz *.zip *.z *.Z *.rpm *.deb *.bz2

# [ftp]
#        path = /home/ftp
#        comment = ftp export area
uid = root
gid = root
max connections = 0
ignore errors
exclude = lost+found/
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsyncd.lock
reverse lookup = no

[backup]
path = /wwwroot/web/ma_tm_system/
comment = backup dir
read only = no
auth users = rsyncuser
secrets file = /etc/rsync.pas

4、密码配置文件rsync.pas 放置在/etc目录下，并修改权限为600

rsyncuser:123456

chmod 600 /etc/rsync.pas

重启rsync服务

systemctl restart rsyncd

5、目标服务器增加脚本用于监控WEB目录发生变化重启Ｃore 服务。

inotify_resetCore.sh

#!/bin/bash
# chkconfig: 2345 10 90
# description: resind
SRC='/wwwroot/web/ma_tm_system/'
inotifywait -mrq --exclude=".*\.swp" --timefmt '%Y-%m-%d %H:%M:%S' --format '%T %w %f' -e create,delete,moved_to,close_write,attrib ${SRC} |while read DATE TIME DIR FILE;
do
     systemctl restart Core.service
 done

脚本放置在　/etc/init.d/下，并增加可执行权限,并配置开机启动。

chmod +x /etc/init.d/inotify_resetCore.sh
chkconfig --add inotify_rsync.sh
