inotify-tools時實調用rsync同步文件

#!/bin/sh 
host1=172.16.18.116
host2=172.16.18.226
src=/home/jfy/tmptmp 
des=/home/jfy 
inotifywait=/usr/local/inotify-tools/bin/inotifywait

/usr/local/inotify-tools/bin/inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f' -e modify,delete,create,attrib ${src} | while read file
do
    echo -e "=== rsync ${host1} ...\n"
    rsync -avtgpro --delete '-e ssh -p 2014' ${src} root@${host1}:${des}
    echo -e "\n"
    echo -e "=== rsync ${host2} ...\n"
    rsync -avtgpro --delete ${src} root@${host2}:${des}
    echo "---------------------------------------------------------------------------------------"
done</pre> 
 
上面這個腳本，當vi一個被監控的文件后wq時，一下子會產生幾千條event，導致rsync被執行幾千次，這是由于文件很大，一直保存過程中就一直會有modify事件，實際上attrib,create,modify可以用close_write來代替，不管是新建，修改，attrib都會有close_write事件。

下面換一種寫法，只要inotifywait返回就執行rsnync，不管具體事件。
#!/bin/sh 
host1=172.16.18.116
host2=172.16.18.226
src=/home/jfy/tmptmp
des=/home/jfy
inotifywait=/usr/local/inotify-tools/bin/inotifywait

while [ 1 -eq 1 ]
do
    echo -e "wait inotify ..."
    /usr/local/inotify-tools/bin/inotifywait -rq --timefmt '%d/%m/%y %H:%M' --format '%T %e %w%f' -e modify,delete,create,attrib ${src} > /dev/null
    echo -e "=== rsync ${host1} ...\n"
    rsync -avtgpro --delete '-e ssh -p 2014' ${src} root@${host1}:${des}
    echo -e "\n"
    echo -e "=== rsync ${host2} ...\n"
    rsync -avtgpro --delete ${src} root@${host2}:${des}
    echo "---------------------------------------------------------------------------------------"
done</pre> 
 
inotifywait還可以從file讀入要監控和要排除的文件或目錄：

/usr/local/inotify-tools/bin/inotifywait -rq --fromfile ../conf/inotify-file-list --timefmt '%d/%m/%y %H:%M' --format '%T %e %w%f' -e modify,delete,create,attrib
 
 
還有一些文件名匹配的選項可用

#!/bin/sh 
host1=172.16.18.116
host2=172.16.18.226
src=/home/jfy/tmptmp
des=/home/jfy
INOTIFY_INCLUDE="--fromfile /usr1/app/conf/inotify_include.list"
RSYNC_EXCLUDE="--include-from=/usr1/app/conf/rsync_include.list --exclude-from=/usr1/app/conf/rsync_exclude.list"

while [ 1 -eq 1 ]
do
    echo -e "wait inotify ..."
    /usr/local/inotify-tools/bin/inotifywait -rq -e modify,delete,create,attrib --exclude "(.log|.swp|.inc|.svn|.rar|.tar.gz|.gz|.txt|.zip|.bak)" $INOTIFY_INCLUDE
    echo -e "=== rsync ${host1} ...\n"
    rsync -avtgpro --delete -e 'ssh -p 2014' $RSYNC_EXCLUDE ${src} root@${host1}:${des}
    echo -e "\n"
    echo -e "=== rsync ${host2} ...\n"
    rsync -avtgpro --delete $RSYNC_EXCLUDE ${src} root@${host2}:${des}
    echo "---------------------------------------------------------------------------------------"
done</pre> 
 
inotify_include.list,@為排除文件

/home/jfy/tmptmp
@/home/jfy/tmptmp/wollar.sql
@/home/jfy/tmptmp/ttt
 
 
–include-from可以指定–exclude-from中的一些特殊文件允許同步

rsync_exclude.list
tmptmp/56.sql
tmptmp/114.sql
 
 
rsync_include.list

tmptmp/114.sql
 
 
上面這兩個文件的結果就是114.sql是會被同步的
