linux开启 Sersync 守护进程进行数据同步
|
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 （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
