sersync的服務設置
sersync可以理解為建立在inotify基礎上的加強版,它可以更加細膩和完美的實現inotify和rsync的能力.
使用sersync就必須安裝inotify和rsync.
1.1 環境nfs客戶端和backup服務端
默認iptables,xelinux已經關閉
1.1.1 nfs客戶端
[[email protected] ~]# uname -a
Linux nfs01 2.6.32-696.el6.x86_64 #1 SMP Tue Mar 21 19:29:05 UTC 2017x86_64 x86_64 x86_64 GNU/Linux
查看是否有inotify,如果沒有下載
[[email protected]
inotify-tools-3.14-1.el6.x86_64
下載方法
yum install inotify-tools -y
設置nfs客戶端的推送目錄
mkdir -p /nfsbackup/
設置rsync的密碼文件,權限,查看
echo "密碼" >/etc/rsync.password
chmod 600 /etc/rsync.password
[[email protected] ~]# ll /etc/rsync.password
-rw------- 1 root root 7 Jun 28 11:21/etc/rsync.password
1.1.2 backup服務端
[[email protected] ~]# uname -a
Linux backup 2.6.32-696.el6.x86_64 #1 SMP Tue Mar 21 19:29:05 UTC 2017x86_64 x86_64 x86_64 GNU/Linux
查看rsync是否啟動(默認已經安裝rsync,如果沒有安裝請看之前發的rsync服務設置)
[[email protected] ~]# ss -lntup|grep rsyn
tcp LISTEN 0 5 :::873 :::* users:(("rsync",1294,5))
tcp LISTEN 0 5 *:873 *:* users:(("rsync",1294,3))
如果沒有啟動請啟動
rsync --daemon
查看rsync的配置文件找到虛擬用戶,用戶密碼,用戶路徑
[[email protected] ~]# cat /etc/rsyncd.conf
######rsync_config_______________start
#created by oldboy 15:01 2007-6-22
#QQ 31333741 blog:http://oldboy.blog.51cto.com
##rsyncd.conf start##
uid=rsync
gid=rsync
use chroot = no
max connections = 200
timeout = 300
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log
ignore errors
list = false
hosts allow = 172.16.1.0/24
#hosts deny = 0.0.0.0/32
auth users = rsync_backup
secrets file = /etc/rsync.password
#rsync_config_______________end
read only = false
[backup]
path = /backup/
[nfsbackup] #模塊的名字
path = /nfsbackup/ #模塊的路徑
ignore errors
read only = false
list = false
hosts allow = 172.16.1.0/24
#hosts deny = 0.0.0.0/32
auth users = rsync_backup #虛擬用戶的用戶名
secrets file = /etc/rsync.password #用戶密碼的路徑
1.2 安裝sersync
1.2.1 去網站下載sersync包
1.2.2 傳輸到nfs服務器
輸入sz選擇sersync包
如果沒有,安裝上傳下載命令
yum install -y lrzsz
解壓sersync包,需要unzip命令
unzip sersync_installdir_64bit.zip
將sersync文件包移動到/usr/local/sersync
mv sersync_installdir_64bit /usr/local/sersync
查看
[[email protected] ~]# tree /usr/local/sersync/
/usr/local/sersync/
├── bin
│ └── sersync
├── conf
│ └── confxml.xml
├── logs
└── sersync
4 directories, 2 files
1.3 設置sersync的配置文件
vim /usr/local/sersync/conf/confxml.xml
<?xml version="1.0"encoding="ISO-8859-1"?>
<head version="2.5">
<hosthostip="localhost" port="8008"></host>

</filter>
<inotify>
<delete start="true"/>
<createFolder start="true"/>
<createFile start="false"/>
<closeWrite start="true"/>
<moveFrom start="true"/>
<modify start="false"/>
</inotify>
<sersync>
<localpath watch="/nfsbackup"> ###填寫nfs客戶端的目錄
<remote ip="172.16.1.41"name="nfsbackup"/>###填寫backup服務端的IP地址和模塊名字
<!--<remote ip="192.168.8.39"name="tongbu"/>-->
<!--<remote ip="192.168.8.40"name="tongbu"/>-->
</localpath>
<rsync>
<commonParams params="-az"/> ###選擇rsync執行的命令參數
<auth start="true" users="rsync_backup"passwordfile="/etc/rsync.password"/>
#####選擇開啟,名字就是rsync的虛擬用戶名,虛擬用戶密碼目錄
<userDefinedPort start="false"port="874"/><!-- port=874 -->
<timeout start="false" time="100"/><!--timeout=100 -->
<ssh start="false"/>
</rsync>
<failLog path="/tmp/rsync_fail_log.sh"timeToExecute="60"/><!--default every 60mins execute once-->

<include expression="(.*)\.sh"/>
</filter>
</plugin>
<plugin name="socket">

1.5 啟動sersync服務
[[email protected] conf]# sersync -rd -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 rsyncall the local files to the remote servers before the sersync work
option: -d runas a daemon
option: -o configxml name： /usr/local/sersync/conf/confxml.xml
daemon thread num: 10
parse xml config file
host ip : localhost hostport: 8008
daemon start，sersync run behind the console
use rsync password-file :
useris rsync_backup
passwordfileis /etc/rsync.password
config xml parse success
please set /etc/rsyncd.conf max connections=0Manually
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 remoteservers once
working please wait...
execute command: cd /nfsbackup && rsync -az -R --delete .[email protected]::nfsbackup --password-file=/etc/rsync.password>/dev/null 2>&1
run the sersync:
watch path is: /nfsbackup
