linux开启 Sersync 守护进程进行数据同步
a、配置 Sersync 环境变量
[root@SERSYNC sersync]# echo 'export PATH=$PATH:/usr/local/sersync/bin'>>/etc/profile
[root@SERSYNC sersync]# tail -1 /etc/profile export PATH=$PATH:/usr/local/sersync/bin [root@SERSYNC sersync]# . /etc/profile [root@SERSYNC 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
[root@SERSYNC ~]# 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
[root@SERSYNC ~]# 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
[root@SERSYNC ~]# 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
_bak@172.16.100.1::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
[root@SERSYNC ~]# 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
[root@SERSYNC ~]# cp /etc/rc.local /etc/rc.local.bak._$(date +%F)
[root@SERSYNC ~]# 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
