rsync+sersync

先前测试过rsync+inotify   大量小文件的同步不适用，太慢。

主130备份到131的配置：

两台机器都要安装好rsync,一般系统都自带，没有yum安装或者源码安装均可。

A:131上的操作：

新建/etc/rsyncd.conf配置文件：

strict modes = yes
port = 873
logfile = /var/log/rsyncd.log
pidfile = /var/run/rsyncd.pid
lock file = /var/run/rsyncd.lock
max connections = 200

[test]         #自定义的模块名，130上sersync会用到
uid = root     #设置运行的权限                                                                                       
gid = root     #设置运行的权限
path = /home/hytest/upload/test  #要存放的数据路径
read only = no #设置文件权限为读写权限
hosts allow = 173.160.201.130
auth users = lipeng #执行数据同步的用户名
secrets file = /etc/rsyncd.scrt #用户认证文件，里面包含用户和密码，跟上面auth users对应

[payCard]
uid = root
gid = root
path = /home/hytest/upload/payCard
read only = no
hosts allow = 173.160.201.130
auth users = lipeng
secrets file = /etc/rsyncd.scrt

[authInfo]
uid = root
gid = root
path = /home/hytest/upload/authInfo
read only = no
hosts allow = 173.160.201.130
auth users = lipeng
secrets file = /etc/rsyncd.scrt

[48502000]
uid = root
gid = root
path = /home/hytest/upload/48502000
read only = no
hosts allow = 173.160.201.130
auth users = lipeng
secrets file = /etc/rsyncd.scrt

[authentication]
uid = root
gid = root
path = /home/hytest/upload/authentication
read only = no
hosts allow = 173.160.201.130
auth users = lipeng
secrets file = /etc/rsyncd.scrt

[branch]
uid = root
gid = root
path = /home/hytest/upload/branch
read only = no
hosts allow = 173.160.201.130
auth users = lipeng
secrets file = /etc/rsyncd.scrt

[elecAgreement]
uid = root
gid = root
path = /home/hytest/upload/elecAgreement
read only = no
hosts allow = 173.160.201.130
auth users = lipeng
secrets file = /etc/rsyncd.scrt

[informationUpload]
uid = root
gid = root
path = /home/hytest/upload/informationUpload
read only = no
hosts allow = 173.160.201.130
auth users = lipeng
secrets file = /etc/rsyncd.scrt

　创建/etc/rsyncd.scrt文件，写入验证的用户和密码：

lipeng:123456

　　权限设置为600，chmod 600 /etc/rsyncd.scrt

启动rsync:

rsync --daemon --config=/etc/rsyncd.conf

rsyncd.conf配置文件内容变更了之后，无需重启该进程。

 

B:130上操作：

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

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

创建/etc/rsyncd.scrt文件，写入密码：

123456

权限设置为600，chmod 600 /etc/rsyncd.scrt

安装sersync:

下载sersync并上传到服务器上：

链接：https://pan.baidu.com/s/1tKwmLaH9aruLs9f4RsFhCg
提取码：dqjw

直接解压tar -zxvf sersync2.5.4_64bit_binary_stable_final\ \(1\).tar.gz

直接mv到自定义的目录下，我这边直接放到/home下的自定义的目录了，便于管理。

mv GNU-Linux-x86/ /home/rsyncto131/sersync

cd /home/rsyncto131/sersync

 

 

 这边演示配置test模块：

修改confxml.xml文件：

 其他的不需要修改。

直接启动sersync:

nohup /rsyncto131/sersync/sersync2 -d -r -o /home/rsyncto131/sersync/confxml.xml  >>nohu.out &

传输的日志需要在131上查看：

tail -f /var/log/rsyncd.log

 

C:多个模块需要相应的多起sersync进程：

131新增的48502000模块，则130上操作：

 cp confxml_authInfo.xml confxml_48502000.xml  #confxml_48502000.xml记得需要修改相应的文件内容

cp nohup.out nohup_48502000.out

启动：

nohup /home/rsyncto131/sersync/sersync2 -d -r -o /home/rsyncto131/sersync/confxml_48502000.xml >> nohup_48502000.out &
