sersync原理是使用rsync命令推送同步的文件到rsync客戶端 優點是同步快，實時同步 使用資源少 缺點是不只是雙向實時同步，也就是說客戶端新建文件不會同步到服務器端 對於要實施雙機實時同步的同學來說sersync不是一個好的辦法
sersync+rsync 客戶端IP爲192.168.16.130 服務器IP爲192.168.16.128
實現目標：服務器端（推送端）/data/同步到客戶端 /tmp/haha
客戶端（只有rsync）配置
yum -y install rsync
vi /etc/rsyncd.conf
uid=root
gid=root
max connections=36000
use chroot=no
log file=/var/log/rsyncd.log
pid file=/var/log/rsyncd.pid
lock file=/var/log/rsyncd.lock
[data] #rsync模塊名，後面配置sersync會用到
path=/tmp/haha #該同步目錄只要uid所指定的用戶有寫權限即可
comment = website files
ignore errors = yes
read only = no
hosts allow = 192.168.16.0/24
#hosts deny = *
auth users = user
secrets file = /etc/rsync.pas
mkdir /tmp/haha
vi /etc/rsync.pas
user:123456
chmod 600 /etc/rsync.pas
rsync --daemon --config=/etc/rsyncd.conf
服務器端配置
yum -y install rsync
cd /usr/src
tar fzxv sersync.tar.gz
mkdir /usr/local/sersync
mkdir /usr/local/sersync/conf
mkdir /usr/local/sersync/bin
mkdir /usr/local/sersync/log
cd GNU-Linux-x86/
cp confxml.xml /usr/local/sersync/conf/
cp sersync2 /usr/local/sersync/bin/
cp /usr/src/GNU-Linux-x86/sersync2 /bin/
vi /etc/rsync.pas
123456
chmod 600 /etc/rsync.pas
cd /usr/local/sersync/conf/
vi confxml.xml
