inotify+rsync实现linux文件批量更新
---恢复内容开始---
公司网站一台服务器顶不住了,就打算用负载均衡,现在是3台机器一起运行网站,之前做的批量更新一直没写日志,现在补上,也是借鉴了不少博客
这里不想编译安装就直接yum了
yum install rsync
//建立配置文件
#touch /etc/rsyncd.conf
//建立帐号配置文件
#touch /etc/rsyncd.pwd
//配置文件只能自己看
#chmod 600 /etc/rsyncd.conf
//帐号配置文件只能自己看
#chmod 600 /etc/rsyncd.pwd
# vi /etc/rsyncd.conf
uid=root gid=root max connections=4 use chroot=yes log file=/var/log/rsyncd.log pid file=/var/run/rsyncd.pid lock file=/var/run/rsyncd.lock #auth users=root secrets file=/etc/rsyncd.pwd [web] path = /home/wwwroot/web1/ comment = welcome to 0.1 ignore errors read only = no list = yes auth users = www
vi /etc/rsyncd.pwd
文件内容如下:
www:xxxxxxxxxxxxxxxxxxxxxx
启动 rsync server (会自动加载配置文件/etc/rsyncd.conf)
#rsync --daemon
如果开启了iptables,要先打开 tcp 873 的 input(入站)规则
设置密码文件
#echo "xxxxxxxxxxxxxxx" >/script/rsync_remote.pwd
密码文件只能自己看
#chmod 600 /script/rsync_remote.pwd
安装inotifywait就不详述
下面是我用来更新执行的脚本
/script/inotify_rsync.sh 注释: host1 host2 为2台需要同步的服务器,如果有更多的服务器需要同步可以在下面增加 ------------------------------------------------------------------------ #!/bin/bash if [ "$1" != "" ] ; then echo "run /etc/init.d/inotify start" exit 1 fi host1=192.168.0.22 host2=192.168.0.23 src=/home/wwwroot/web1/ src2="`echo $src | sed -e ‘s/\//+++/g‘`" des=web user=www rsync_exclude_file=/script/rsync_skip.setup password_file=/script/rsync_remote.pwd do_rsync() { files=$1 user=$2 host=$3 des_url=$4 rsync_exclude_file=$5 password_file=$6 /usr/bin/rsync --delete -zrtopg --exclude-from=${rsync_exclude_file} --progress --password-file=${password_file} ${files} $user@$host::$des_url } #echo "src2:$src2" /usr/local/inotify/bin/inotifywait --excludei ‘(.svn|.swp|.swo|Runtime)‘ -mrq --timefmt ‘%d/%m/%y %H:%M‘ --format ‘%w::%f‘ -e close_write,delete,create,attrib $src | while read filess do files=`echo "$filess" | awk -F:: ‘{print $1}‘` file=`echo "$filess" | awk -F:: ‘{print $2}‘` des_dir=`echo "$files" | sed -e ‘s/\//+++/g‘ -e "s/${src2}/\//g" -e ‘s/+++/\//g‘` des_url="${des}${des_dir}" do_rsync "$files" "$user" "$host1" "$des_url" "$rsync_exclude_file" "$password_file" do_rsync "$files" "$user" "$host2" "$des_url" "$rsync_exclude_file" "$password_file" echo "`date` dir:${files} , file:${file} was rsync to ${host1},${host2}/${des_url}" >> /home/rsync.log done ---------------------------------------------------------------------------------------------- /etc/init.d/inotify #! /bin/sh ### BEGIN INIT INFO # Provides: inotify # Required-Start: $remote_fs $network # Required-Stop: $remote_fs $network # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: starts inotify # Description: starts the PHP FastCGI Process Manager daemon ### END INIT INFO case "$1" in start) echo -n "Starting inotify " /script/inotify_rsync.sh& if [ "$?" != 0 ] ; then echo " failed" exit 1 fi sleep 2 if [ "`ps aux | grep inotifywait | wc -l`" -gt 1 ] ; then echo " done" else echo " failed" exit 1 fi ;; stop) echo -n "Gracefully shutting down inotify" killall inotifywait killall inotify_rsync.sh sleep 2 if [ "`ps aux | grep inotifywait | wc -l`" -gt 1 ] ; then echo " failed" exit 1 else echo " done" exit 1 fi ;; restart) $0 stop $0 start ;; *) echo "Usage: $0 {start|stop|restart}" exit 1 ;; esac
