测试环境
需求:服务器A与服务器B为主备服务模式,需要保持文件一致性,现采用sersync基于rsync+inotify实现数据实时同步
环境描述:
主服务器172.26.7.50 ,从服务器172.26.7.51
实时同步/home/ 及/download 目录到从服务器
下载地址:http://rsync.samba.org/ftp/rsync/src
可根据环境需求下载相应的软件版本,本实验下载版本为rsync-3.1.1.tar.gz
cd /usr/src
wget http://rsync.samba.org/ftp/rsync/src/rsync-3.1.1.tar.gz
解压
tar xf rsync-3.1.1.tar.gz –C /opt/
mv /opt/rsync-3.1.1 /opt/rsync
cd /opt/rsync
./configure
make && make install
创建rsyncd.conf文件
vi /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
[tongbu] #认证模块名
path = /opt/tongbu #同步A服务器的文件路径
ignore errors = yes #忽略无关错误信息
hosts allow = 172.26.7.50 #允许访问IP
hosts deny = * #除了172.26.7.50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 = /download
ignore errors = yes
hosts allow = 172.26.7.50
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172.26.7.0/24
也可为172.26.7.0/255.255.255.0
创建rsync.pass文件
echo “root:password”>>/etc/rsync.pass
chmod 600 /etc/rsync.pass
rsync --daemon –v
echo “rsync --daemon –v”>>/etc/rc.local
开机自启动

编译安装rsync
cd rsync
./configure && make && make install
编译安装inotify-tools
cd inotify-tools
./configure && make && make install

配置密码文件
echo “password”>>/opt/sersync/user.pass
注:文件权限必须为600否则启动异常
nohup /opt/sersync/sersync2 -r -d -o /opt/sersync/confxml.xml >/opt/sersync/rsync.log 2>&1 &
#######如果是多个目录同步需要启动两个进程
nohup /opt/sersync/sersync2 -r -d -o /opt/sersync/downxml.xml >/opt/sersync/downrsync.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
验证
在主服务器上的/opt/tongbu及/home目录下创建文件查看从服务器172.26.7.51上是否有同步
