这2天一直忙其它的事,忘记把剩余的同步过程分享到博客中,望谅解!上周把rsync已经配置完成,可以手动的同步,下面我们将使用Serync进行实时的同步,其实就手动同步而言也可以配置crontab定时备份,因人而异方法很多,选一种适合你自己的。
三、Serync Configuration
首先下载软件
[root@nagios01 /]#cd /home/qiuyuetao/
[root@nagios01 qiuyuetao]# wget
http://sersync.googlecode.com/files/sersync2.5.4_64bit_binary_stable_final.tar.gz
【http://code.google.com/p/sersync/】下载网站
1,安装sersync
[root@nagios01 qiuyuetao]# tar -zxvf sersync2.5.4_64bit_binary_stable_final.tar.gz -C /usr/local/(-C 解压到指定路径)
[root@nagios01 qiuyuetao]# mv /usr/local/GNU-Linux-x86 sersync
[root@nagios01 local]# tree sersync/
sersync/
├── confxml.xml
└── sersync2
2,规范 sersync 目录结构(自行抉择是否规范)
mkdir conf bin logs (配置文件放到conf、二进制命令Bin下、脚本logs下)
[root@nagios01 local]# cd sersync/
[root@nagios01 sersync]# mkdir conf bin logs
[root@nagios01 sersync]# mv confxml.xml conf/
[root@nagios01 sersync]# mv sersync2 bin/sersync
[root@nagios01 sersync]# tree
.
├── bin
│ └── sersync
├── conf
│ └── confxml.xml
└── logs
3 directories, 2 files
3,编辑配置文件
备份 cp confxml.xml confxml.xmlq.$(date +%F)
4,更改及优化sersync 配置
(1)定义本地的同步目录
24 <localpath watch="/opt/tongbu">要同步的目录
25 <remote ip="127.0.0.1" name="tongbu1"/>
26 <!--<remote ip="192.168.8.39" name="tongbu"/>-->
同步到哪台机器 同步到那个模块目录
27 <!--<remote ip="192.168.8.40" name="tongbu"/>-->
28 </localpath>
修改后内容为:
<sersync>
<localpath watch="/usr/local/nagios/etc/cfgs">
<remote ip="192.168.1.206" name="cfgs"/>
</localpath>
<!--###############################################################-->
<localpath watch="/usr/local/nagios/etc/objects">
<remote ip="192.168.1.206" name="objects"/>
</localpath>
<!--###############################################################-->
修改前
<rsync>
40 <commonParams params="-artuz"/>
41 <auth start="false" users="root" passwordfile="/etc/rsync.pas"/>
使用认证
42 <userDefinedPort start="false" port="874"/><!-- port=874 -->
43 <timeout start="false" time="100"/><!-- timeout=100 -->
44 <ssh start="false"/>
45 </rsync>
修改后内容为:拼接同步命令
<rsync>
<commonParams params="-artuz"/>
<auth start="true" users="rsync_backup" passwordfile="/etc/rsync.password"/>
<userDefinedPort start="false" port="874"/><!-- port=874 -->
<timeout start="true" time="100"/><!-- timeout=100 -->
<ssh start="false"/>
</rsync>
修改36-37行 失败后会写入log
<failLog path="/tmp/rsync_fail_log.sh" timeToExecute="60"/><!--default every 60mins execute once-->
修改后内容
<failLog path="/usr/local/sersync/logs/rsync_fail_log.sh" timeToExecute="60"/><!--default every 60mins
execute once-->
4,开启sersync守护进程同步数据(全局变量)
echo 'export PATH=$PATH:/usr/local/sersync/bin'>>/etc/profile
tail -1 /etc/profile (查看是否添加)
source /etc/profile (使/etc/Porofile 立即生效)
which sersync (查看sersync命令路径能否找到)
5,《启动同步命令》
sersync -r(先做一次同步) -d(后台启动) -o(指定文件) /usr/local/sersync/conf/confxml.xml
sersync -r -d -o /usr/local/sersync/conf/confxml.xml
[root@Server conf]# sersync -r -d -o /usr/local/sersync/conf/confxml.xml
(启动过程)
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 默认启动10个线程
parse xml config file
host ip : localhost host port: 8008
daemon start,sersync run behind the console
use rsync password-file : 密码文件
user is rsync_backup 用户
passwordfile is /etc/rsync.password
config xml parse success
please set /etc/rsyncd.conf max connections=0 Manually
sersync working thread 12 工作线程数 = 1(primary thread) + 1(fail retry thread) + 10(daemon sub threads)
Max threads numbers is: 32最大线程数 = 12(Thread pool nums) + 20(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 /usr/local/nagios/etc/cfgs && rsync -artuz -R --delete ./ --timeout=100
rsync_backup@192.168.1.206::cfgs --password-file=/etc/rsync.password >/dev/null 2>&1
[root@nagios01 conf]# run the sersync:
watch path is: /usr/local/nagios/etc/cfgs
成功
6,#####测试结果:发现一个问题,仅能同步一个模块目录 cfgs模块 / objects 没有同步
[root@nagios01 conf]# touch /usr/local/nagios/etc/cfgs/1.txt /usr/local/nag
ios/etc/objects/1.txt
[root@nagios01 conf]# tree /usr/local/nagios/etc/
/usr/local/nagios/etc/
├── cfgs
│ ├── 1.txt
│ ├── cfgs.log
├── objects
│ ├── 1.txt
│ ├── objects.log
│
[root@Nagios02 /usr/local/nagios/etc]$tree
├── cfgs
│ ├── 1.txt
│ ├── cfgs.log
├── objects
│ ├── objects.log
7,####如下是采用多实例的方法进行 同时同步2个目录#####
创建2个文件
cp confxml.xml confxml.xml_new
cp confxml.xml cfgs_confxml.xml
cp confxml.xml objects_confxml.xml
规范目录看着舒服多了
[root@nagios01 conf]# ll
total 12
-rwxr-xr-x. 1 root root 2328 Feb 23 00:49 cfgs_confxml.xml
-rwxr-xr-x. 1 root root 2339 Feb 23 00:50 objects_confxml.xml
drwxr-xr-x. 2 root root 4096 Feb 23 00:51 tmp
8,配置文件内容删除多余节点目录 修改日志报错名称 如下是比对结果
[root@nagios01 conf]# diff cfgs_confxml.xml objects_confxml.xml
23,24c23,24
< <localpath watch="/usr/local/nagios/etc/cfgs">
< <remote ip="192.168.1.206" name="cfgs"/>
---
> <localpath watch="/usr/local/nagios/etc/objects">
> <remote ip="192.168.1.206" name="objects"/>
34c34
< <failLog path="/usr/local/sersync/logs/cfgs_rsync_fail_log.sh" timeToExecute="60"/><!--default every 60mins
execute once-->
---
> <failLog path="/usr/local/sersync/logs/objects_rsync_fail_log.sh" timeToExecute="60"/><!--default every
60mins execute once-->
9,更新sersync运行状态
[root@nagios01 conf]# ps -ef|grep sersync
root 6134 1 0 Feb22 ? 00:00:00 sersync -r -d -o /usr/local/sersync/conf/confxml.xml
root 7178 2428 0 00:55 pts/0 00:00:00 grep sersync
[root@nagios01 conf]# pkill sersync
[root@nagios01 conf]# ps -ef|grep sersync
root 7187 2428 0 00:56 pts/0 00:00:00 grep sersync
10,同时启动2个配置文件,各自指定各自的配置文件(配置要求高些,进程数随之调整)
sersync -r -d -o /usr/local/sersync/conf/cfgs_confxml.xml
sersync -r -d -o /usr/local/sersync/conf/objects_confxml.xml
[root@nagios01 conf]# ps -ef |grep sersync
root 7290 1 0 01:01 ? 00:00:00 sersync -r -d -o /usr/local/sersync/conf/cfgs_confxml.xml
root 7308 1 0 01:01 ? 00:00:00 sersync -r -d -o /usr/local/sersync/conf/objects_confxml.xml
root 7327 2428 0 01:01 pts/0 00:00:00 grep sersync
11,在做一下测试
[root@nagios01 conf]# touch /usr/local/nagios/etc/cfgs/2.txt /usr/local/nagios/etc/objects/2.txt
[root@nagios01 conf]# tree /usr/local/nagios/etc/
/usr/local/nagios/etc/
├── cfgs
│ ├── 1.txt
│ ├── 2.txt
│ ├── cfgs.log
├── objects
│ ├── 1.txt
│ ├── 2.txt
│ ├── objects.log
│
[root@Nagios02 /usr/local/nagios/etc]$tree
├── cfgs
│ ├── 1.txt
│ ├── 2.txt
│ ├── cfgs.log
├── objects
│ ├── 1.txt
