linux开启 Sersync 守护进程进行数据同步

概述a、配置 Sersync 环境变量   [[email protected] sersync]# echo ‘export PATH=$PATH:/usr/local/sersync/bin‘>>/etc/profile   [[email protected] sersync]# tail -1 /etc/profile export PATH=$PATH:/usr/local/sersync/

a、配置 Sersync 环境变量

 

[[email protected] sersync]# echo ‘export PATH=$PATH:/usr/local/sersync/bin‘>>/etc/profile

 

[[email protected] sersync]# tail -1 /etc/profile export PATH=$PATH:/usr/local/sersync/bin [[email protected] sersync]# . /etc/profile [[email protected] sersync]# which sersync

 

 

启动的过程及结果：

 

注意：我们这里要启动的是多实例，即 confxml.xml 和 download_confxml.xml

 

[[email protected] ~]# ls /usr/local/sersync/conf/*

 

/usr/local/sersync/conf/confxml.xml

 

/usr/local/sersync/conf/confxml.xml.bak.2014-06-04

 

/usr/local/sersync/conf/download_confxml.xml

 

 

[[email protected] ~]# sersync -r -d -o /usr/local/sersync/conf/confxml.xml

 

 

set the system param

 

 

execute：echo 50000000 > /proc/sys/fs/inotify/max_user_watches

 

 

execute：echo 327679 > /proc/sys/fs/inotify/max_queued_events

 

 

parse the command param

 

 

option: -r rsync all the local files to the Remote Servers before the sersync work

 

 

option: -d run as a daemon

 

 

option: -o config xml name： /usr/local/sersync/conf/confxml.xml

 

 

daemon thread num: 10

 

 

parse xml config file

 

 

host ip : localhosthost port: 8008

 

 

daemon start，sersync run behind the  console

 

 

use rsync password-file :

 

 

user isrsync_bak

 

passwordfile is /etc/rsync.password config xml parse success

please set /etc/rsyncd.conf max connections=0 Manually

 

sersync working thread 12 = 1(primary thread) + 1(fail retry thread) + 10(daemon sub thr eads)

Max threads numbers is: 32 = 12(Thread pool nums) + 20(Sub threads)

 

 

chmod: cannot access `/usr/local/logs/rsync_fail_log.sh‘: No such file or directory

 

------------------------------------------

 

rsync the directory recursivly to the Remote Servers once working please wait...

execute command: cd /data/web && rsync -aruz -R --delete ./ --timeout=100 rsync_bak

 

@172.16.100.1::web --password-file=/etc/rsync.password >/dev/null 2>&1

 

 

run the sersync:

 

 

watch path is: /data/web

 

 

[[email protected] ~]# sersync -r -d -o /usr/local/sersync/conf/download_confxml.xml

 

 

set the system param

 

 

execute：echo 50000000 > /proc/sys/fs/inotify/max_user_watches

 

 

execute：echo 327679 > /proc/sys/fs/inotify/max_queued_events

 

 

parse the command param

 

 

option: -r rsync all the local files to the Remote Servers before the sersync work

 

 

option: -d run as a daemon

 

 

option: -o config xml name： /usr/local/sersync/conf/download_confxml.xml

 

 

daemon thread num: 10

 

 

parse xml config file

 

 

host ip : localhosthost port: 8008

 

 

daemon start，sersync run behind the console

 

use rsync password-file :

 

user isrsync_bak

 

passwordfile is /etc/rsync.password config xml parse success

please set /etc/rsyncd.conf max connections=0 Manually

 

 

eads)

 

Max threads numbers is: 32 = 12(Thread pool nums) + 20(Sub threads)

 

please according your cpu ，use -n param to adjust the cpu rate

 

chmod: cannot access `/usr/local/logs/rsync_fail_log.sh‘: No such file or directory

 

------------------------------------------

 

rsync the directory recursivly to the Remote Servers once

 

 

working please wait...

 

 

execute command: cd /data/download && rsync -aruz -R --delete ./ --timeout=100 rsync

 

 

[email protected]::download --password-file=/etc/rsync.password >/dev/null 2>&1

 

 

run the sersync:

 

 

watch path is: /data/download

 

b、开启后查看进程

 

 

[[email protected] ~]# ps -ef |grep sersync

 

 

root      2114     1 0 01:56 ?        00:00:00 sersync -r -d -o /usr/local/sersync/conf/confxml.

 

 

xml

 

 

root      2223     1 0 02:03 ?        00:00:00 sersync -r -d -o /usr/local/sersync/conf/downloa

 

 

d_confxml.xml

 

 

root      2295 2244 0 02:08 pts/2    00:00:00 grep sersync

 

 

C、配置开机自启动

 

 

[[email protected] ~]# cp /etc/rc.local /etc/rc.local.bak._$(date +%F)

 

[[email protected] ~]# cat >>/etc/rc.local<< ‘EOF‘

 

> # sync data to 172.16.100.1,172.16.100.2

 

> sersync -d -o /usr/local/sersync/conf/confxml.xml

 

> sersync -d -o /usr/local/sersync/conf/download_confxml.xml

 

> EOF
