| 服务器名称 | 角色 | ip | 系统 |
|---|---|---|---|
| 服务器A | 主服务器 | 192.168.33.101 | centos6 x86_64 |
| 服务器B | 备服务器 | 192.168.33.102 | centos6 x86_64 |
架构介绍：
服务器A-安装rsync、inotify、sersync
服务器B-安装rsync
部署用于接收文件的rsync
# 编译安装rsync wget https://download.samba.org/pub/rsync/src/rsync-3.1.2.tar.gz tar zxf rsync-3.1.2.tar.gz cd rsync-3.1.2 ./configure make && make install
服务器A上的sersync会与此daemon对接同步文件
# 1. 编写rsync daemon的配置文件 vim /etc/rsyncd.conf ********************************* uid=root gid=root max connections=36000 use chroot=no log file=/var/log/rsyncd.log pid file=/var/run/rsyncd.pid lock file=/var/run/rsyncd.lock [website] path=/home/website comment = markdream website ignore errors = yes read only = no hosts allow = 192.168.33.101/32 hosts deny = * auth users = userB secrets file = /etc/rsyncd.pass ********************************* # 2. 编写rsync daemon的用户密码文件 vim /etc/rsyncd.pass ********************************* userB:passwordB *********************************
rsync --daemon
# 会默认使用/etc/rsyncd.conf，可使用--config自定义
部署rsync、inotify、sersync
# 安装同服务器B
wget https://github.com/downloads/rvoicilas/inotify-tools/inotify-tools-3.14.tar.gz tar zxf inotify-tools-3.14.tar.gz cd inotify-tools-3.14 ./configure make && make install
wget https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/sersync/sersync2.5.4_64bit_binary_stable_final.tar.gz tar zxf sersync2.5.4_64bit_binary_stable_final.tar.gz mv GNU-Linux-x86/ /usr/local/sersync
cd /usr/local/sersync/ vim confxml.xml ********************************* ... <sersync> <localpath watch="/home/webserver"> <remote ip="192.168.33.102" name="website"/> </localpath> <rsync> <commonParams params="-artuz"/> <auth start="true" users="userB" passwordfile="/usr/local/sersync/user.pass"/> <userDefinedPort start="false" port="874"/><!-- port=874 --> <timeout start="false" time="100"/><!-- timeout=100 --> <ssh start="false"/> </rsync> ... <crontab start="false" schedule="600"><!--600mins--> <crontabfilter start="false"> <exclude expression="*.php"></exclude> <exclude expression="info/*"></exclude> </crontabfilter> </crontab> ... </sersync> ... ********************************* # 在sersync中配置localpath,其中watch为服务器A上需要备份的目录 # 在sersync中配置remote ip,其中ip为服务器B的ip,name对应服务器B的rsync daemon中配置的项目 # 在sersync的rsync配置块中配置auth,start设置为true，user指定服务器B上配置的userB,passwordfile指定密码文件 # 在sersync中的crontab配置块中,也可以配置crontab的频率
此文件用于通过服务器B的rsync daemon认证
vim /usr/local/sersync/user.pass ********************************* passwordB ********************************* # 修改密码文件权限 chmod 600 /usr/local/sersync/user.pass
cd /usr/local/sersync ./sersync2 -r -d -o 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： confxml.xml daemon thread num: 10 parse xml config file host ip : localhost host port: 8008 daemon start，sersync run behind the console use rsync password-file : user is userB passwordfile is /usr/local/sersync/user.pass 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 threads) Max threads numbers is: 22 = 12(Thread pool nums) + 10(Sub threads) please according your cpu ，use -n param to adjust the cpu rate ------------------------------------------ rsync the directory recursivly to the remote servers once working please wait... execute command: cd /home/webserver && rsync -artuz -R --delete ./ userB@192.168.33.102::website --password-file=/usr/local/sersync/user.pass >/dev/null 2>&1 run the sersync: watch path is: /home/webserver # 从启动输出中可以看出,其实sersync调用的就是rsync命令
多写几个配置文件，每个配置文件配置不同的local_path，然后多起几个进程（指定不同配置文件）
