lsync 是啥呢? 其实可以简单的理解成inotufy+rsync,
机器角色:
A 10.210.71.144 安装了 rsync lsync
B 10.210.71.146 安装了 rsync
A机器做出了改变,会在某个特定的时间内,将变化同步到B,甚至更多的机器,inotify 感知文件的变化,rsync 用来把文件推送过去。
配置方案如下:
B机器上的配置:
安装rsync,目录树如下所示:
- [root@test test]
- /etc/rsyncd
- ├── rsyncd.conf
- ├── rsyncd.motd
- └── rsyncd.secrets
-
- 0 directories, 3 files
为了方便,简单的配置文件如下所示:- [root@test test]
- pid file = /var/run/rsyncd.pid
- uid = root
- gid = root
- use chroot = yes
- read only = no
- write only = no
- hosts allow = 10.209.65.21 10.210.71.146 192.168.0.1/255.255.255.0 198.162.145.1 10.0.1.0/255.255.255.0 10.210.71.145 10.210.71.144 10.210.71.143
- hosts deny = *
- max connections = 5
-
- log file = /tmp/rsyncd.log
- transfer logging = yes
- log format = %t %a %m %f %b
- syslog facility = local3
- timeout = 300
-
- [data1]
- path=/tmp/test
- list=yes
- comment = some description about this moudle
- exclude = test1/ test2/
- [root@test test]
- [root@test test]
- pid file = /var/run/rsyncd.pid
- uid = root
- gid = root
- use chroot = yes
- read only = no
- write only = no
- hosts allow = 10.210.71.146 10.210.71.145 10.210.71.144 10.210.71.143
- hosts deny = *
- max connections = 5
-
- log file = /tmp/rsyncd.log
- transfer logging = yes
- log format = %t %a %m %f %b
- syslog facility = local3
- timeout = 300
-
- [data1]
- path=/tmp/test
在A机器上执行如下的命令进行测试:- [root@test test]
- drwxr-xr-x 4096 2015/01/23 13:28:53 .
- -rw-r--r-- 0 2015/01/23 13:28:53 test
- [root@test test]
通了,配置成功。配置A,A上面需要安装inotify 和lsync,比较新版本的系统可以支持yum安装了,省略
A机器上最简单的一个配置:
- [root@test test]
- ----
- -- User configuration file for lsyncd.
- --
- -- Simple example for default rsync, but executing moves through on the target.
- --
- -- For more examples, see /usr/share/doc/lsyncd*/examples/
- --
- --
- -- sync{
- -- default.rsync,
- -- source="/tmp/",
- -- host="10.210.71.146",
- -- targetdir="/tmp/test/"
- --}
- settings {
- logfile = "/var/log/lsyncd.log",
- statusFile = "/var/log/lsyncd-status.log",
- statusInterval = 20
- }
-
- sync{
- default.rsync,
- source = "/tmp/test",
- target = "10.210.71.146::data1/",
- }
-
-
-
- [root@test test]
source 指定的是A端的目录,B目录需要去同步的目录target 指定的是B端的需要承接同步目录的目录。
测试如下
- [root@test test]
- drwxr-xr-x 4096 2015/01/23 13:28:53 .
- -rw-r--r-- 0 2015/01/23 13:28:53 test
- [root@test test]
- /tmp/test
- [root@test test]
- total 0
- -rw-r--r-- 1 root root 0 Jan 23 13:28 test
- [root@test test]
- [root@test test]
- Fri Jan 23 13:46:38 CST 2015
- [root@test test]
- drwxr-xr-x 4096 2015/01/23 13:28:53 .
- -rw-r--r-- 0 2015/01/23 13:28:53 test
- [root@test test]
- Fri Jan 23 13:46:51 CST 2015
- [root@test test]
- Fri Jan 23 13:47:21 CST 2015
- [root@test test]
- drwxr-xr-x 4096 2015/01/23 13:46:37 .
- -rw-r--r-- 0 2015/01/23 13:28:53 test
- -rw-r--r-- 0 2015/01/23 13:46:37 test1
- [root@test test]
同步的工具很多,但是感觉这个非常的易用。
