rsync + inotify 同步

1. 配置rysnc server：同步机，同步被同步机更新的文件，很多台
vi /etc/rsyncd.conf
uid=root
gid=root
use chroot=no
max connections=10
timeout=600
strict modes=yes
port=873
pid file=/var/run/rsyncd.pid
lock file=/var/run/rsyncd.lock
log file=/var/log/rsyncd.log
[module_pk10]
path=/data/www/DePK10
comment=rsync pk10 unity
auth users=pk10
uid=root
gid=root
secrets file=/etc/rsyncd.secrets
read only=no
list=no
hosts allow=103.x.x.x
hosts deny=0.0.0.0/32

vi /etc/rsyncd.secrets
pk10:Lishen@123
chmod 600 /etc/rsyncd.secrets

启动：rsync --daemon

添加防火墙开放 873端口
-A INPUT -m state --state NEW -m tcp -p tcp -s 103.x.x.x --dport 873 -j ACCEPT

2. 客户端：被同步机一台，更新文件只需要更新到这台
vi /etc/rsync_client.pwd
Lishen@123
chmod 600 /etc/rsync_client.pwd

mkdir  /etc/rsyncd.d/
touch  /etc/rsyncd.d/rsync_exclude.lst

安装inotify：yum install -y inotify-tools

监控和同步脚本：
vi rsync.sh
#rsync auto sync script with inotify

#variables
current_date=$(date +%Y%m%d_%H%M%S)
source_path=/data/www/DePK10/
log_file=/var/log/rsync_client.log

#rsync
rsync_server="xxx.xxx.xxx.xxx

xxx.xxx.xxx.xxx"

rsync_user=pk10
rsync_pwd=/etc/rsync_client.pwd
rsync_module=module_pk10
INOTIFY_EXCLUDE='(.*/*\.log|.*/*\.swp)$'
RSYNC_EXCLUDE='/etc/rsyncd.d/rsync_exclude.lst'

#rsync client pwd check
if [ ! -e ${rsync_pwd} ];then
    echo -e "rsync client passwod file ${rsync_pwd} does not exist!"
    exit 0
fi
#inotify_function
inotify_fun(){
    /usr/bin/inotifywait -mrq --timefmt '%Y/%m/%d-%H:%M:%S' --format '%T %w %f' \
          --exclude ${INOTIFY_EXCLUDE}  -e modify,delete,create,move,attrib ${source_path} \
          | while read file
      do
          for server in $rsync_server
          do
              /usr/bin/rsync -auvrtzopgP --delete --exclude-from=${RSYNC_EXCLUDE} --progress --bwlimit=200 --password-file=${rsync_pwd} ${source_path} ${rsync_user}@${server}::${rsync_module}
          done
      done
}
#inotify log
inotify_fun >> ${log_file} 2>&1 &
