sersync的服务设置
sersync可以理解为建立在inotify基础上的加强版,它可以更加细腻和完美的实现inotify和rsync的能力.
使用sersync就必须安装inotify和rsync.
1.1 环境nfs客户端和backup服务端
默认iptables,xelinux已经关闭
1.1.1 nfs客户端
[root@nfs01 ~]# 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,如果没有下载
[root@nfs01 ~]# rpm -qa inotify-tools
inotify-tools-3.14-1.el6.x86_64
下载方法
yum install inotify-tools -y
设置nfs客户端的推送目录
mkdir -p /nfsbackup/
设置rsync的密码文件,权限,查看
echo "密码" >/etc/rsync.password
chmod 600 /etc/rsync.password
[root@nfs01 ~]# ll /etc/rsync.password
-rw------- 1 root root 7 Jun 28 11:21/etc/rsync.password
1.1.2 backup服务端
[root@backup ~]# 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是否启动(默认已经安装rsync,如果没有安装请看之前发的rsync服务设置)
[root@backup ~]# ss -lntup|grep rsyn
tcp LISTEN 0 5 :::873 :::* users:(("rsync",1294,5))
tcp LISTEN 0 5 *:873 *:* users:(("rsync",1294,3))
如果没有启动请启动
rsync --daemon
查看rsync的配置文件找到虚拟用户,用户密码,用户路径
[root@backup ~]# 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] #模块的名字
path = /nfsbackup/ #模块的路径
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 #虚拟用户的用户名
secrets file = /etc/rsync.password #用户密码的路径
1.2 安装sersync
1.2.1 去网站下载sersync包
1.2.2 传输到nfs服务器
输入sz选择sersync包
如果没有,安装上传下载命令
yum install -y lrzsz
解压sersync包,需要unzip命令
unzip sersync_installdir_64bit.zip
将sersync文件包移动到/usr/local/sersync
mv sersync_installdir_64bit /usr/local/sersync
查看
[root@nfs01 ~]# tree /usr/local/sersync/
/usr/local/sersync/
├── bin
│ └── sersync
├── conf
│ └── confxml.xml
├── logs
└── sersync
4 directories, 2 files
1.3 设置sersync的配置文件
vim /usr/local/sersync/conf/confxml.xml

<auth start="true" users="rsync_backup"passwordfile="/etc/rsync.password"/>

1.4 查看使用说明
[root@nfs01 ~]# sersync -h
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
_______________________________________________________
参数-d:启用守护进程模式
参数-r:在监控前，将监控目录与远程主机用rsync命令推送一遍
c参数-n: 指定开启守护线程的数量，默认为10个
参数-o:指定配置文件，默认使用confxml.xml文件
参数-m:单独启用其他模块，使用 -m refreshCDN 开启刷新CDN模块
参数-m:单独启用其他模块，使用 -m socket 开启socket模块
参数-m:单独启用其他模块，使用 -m http 开启http模块
不加-m参数，则默认执行同步程序

1.5 启动sersync服务
[root@nfs01 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 ./rsync_backup@172.16.1.41::nfsbackup --password-file=/etc/rsync.password>/dev/null 2>&1
run the sersync:
watch path is: /nfsbackup
