主服务器192.168.222.4 CentOS7
从服务器192.168.222.5 CentOS6
实时同步/home/data1目录到从服务器
从服务器192.168.222.5操作
# yum -y install rsync*
创建rsyncd.conf文件
vim /etc/rsyncd.conf
uid = root #以root用户运行rsync服务
gid = root #以root用户运行rsync服务
use chroot = no #增加对目录文件软连接的备份
max connections = 1200 #最大连接数
timeout = 800 #超时时间
pid file = /var/run/rsyncd.pid #PID存放位置
lockfile = /var/run/rsyncd.lock #锁文件存放位置
log file = /var/log/rsyncd.log #日志存放位置
[synchronization] #认证模块名
path = /home/data1 #同步A服务器的文件路径
ignore errors = yes #忽略无关错误信息
hosts allow = 192.168.222.5 #允许访问IP
hosts deny = * #除了从主机外拒绝所有
read only = no #允许上传
write only = no #允许下载
list = yes #允许列出同步目录
auth users = root #同步的用户
secrets file = /etc/rsync.pass #存放用户密码的文件
###########可以配置多个同步模块
[download]
path = /home/download
ignore errors = yes
hosts allow = 192.168.222.5
hosts deny = *
read only = no
list = yes
auth users = root
secrets file = /etc/rsync.pass
注：/etc/rsync.pass 文件格式为username:password文件权限必须为600否则服务不正常,hosts allow 定义可为单独IP也可为网段，网段格式为192.168.222.0/24也可为192.168.222.0/255.255.255.0
创建rsync.pass文件
# echo “root:password” >> /etc/rsync.pass
# chmod 600 /etc/rsync.pass
启动服务
# rsync --daemon –v
开机自启动
# echo “rsync --daemon –v” >> /etc/rc.local

配置密码文件
echo “password” > /usr/local/sersync/user.pass
注：文件权限必须为600否则启动异常
chmod 600 /usr/local/sersync/user.pass
2.4服务启动
nohup /usr/local/sersync/sersync2 -r -d -o /usr/local/sersync/confxml.xml > /usr/local/sersync/rsync.log 2>1
#######如果是多个目录同步需要启动两个进程
nohup /usr/local/sersync/sersync2 -r -d -o /usr/local/sersync/downxml.xml > /usr/local/sersync/rsync.log 2>1
-d:启用守护进程模式
-r:在监控前，将监控目录与远程主机用rsync命令推送一遍
-n:指定开启守护线程的数量，默认为10个
-o:指定配置文件，默认使用confxml.xml文件
开机启动写入/etc/rc.local文件中
rsync+inotify实现数据实时同步
