rsync+sersync2文件同步
环境：centos6.5
软件：rsync+sersync2
源服务器：192.168.10.109
同步服务器：192.168.10.107,192.168.10.108
前提工作：
关闭SELINUX
vi /etc/selinux/config
#SELINUX=enforcing
修改
SELINUX=disabled
重启系统生效
iptables打开端口
vi /etc/sysconfig/iptables
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 873 -j ACCEPT
service iptables restart
同步服务器环境配置
安装：
yum -y install rsync
配置
vi /etc/rsyncd.conf
log file = /var/log/rsyncd.log
pidfile = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
secrets file = /etc/rsync.passwd
motd file = /etc/rsyncd.Motd
[web]
path = /web
comment = web
uid = www
gid = www
port=873
use chroot = no
read only = no
list = no
max connections = 200
timeout = 600
auth users = sam
hosts allow = 192.168.10.109
创建密码文件
vi /etc/rsync.passwd
sam:tcg2015
设置文件权限
chmod 600 /etc/rsync.passwd
chmod 600 /etc/rsyncd.conf
启动服务：
rsync --daemon --config=/etc/rsyncd.conf
两台同步服务器都是一样配置
源服务器环境配置：
安装：
yum -y install rsync
查看服务器内核是否支持inotify
ll /proc/sys/fs/inotify
-rw-r--r-- 1 root root 0 Aug 12 11:20 max_queued_events
-rw-r--r-- 1 root root 0 Aug 12 11:41 max_user_instances
-rw-r--r-- 1 root root 0 Aug 12 11:20 max_user_watches
修改系统默认参数
vi /etc/sysctl.conf
在最后添加：
fs.inotify.max_queued_events=99999999
fs.inotify.max_user_watches=99999999
fs.inotify.max_user_instances=65535
立刻生效
sysctl -p

创建验证密码文件：
vi /etc/rsync.passwd
tcg2015
修改文件权限
chmod 600 /etc/rsync.passwd
完全同步一次文件：
/usr/local/sersync/bin/sersync2 -r -o /usr/local/sersync/conf/confxml.xml
同步完成后，kill掉sersync2进程
启动进程
/usr/local/sersync/bin/sersync2 -d -o /usr/local/sersync/conf/confxml.xml
