sersync服务的搭建

sersync服务

首先准备三台机器

M-server

S1-server

S2-server

1、首先在在S1-server 与 S2-server上部署rsync 服务

配置文件如下：

[root@S1-Server ~]# cat /etc/rsyncd.conf

#rsync_config_______________start

##rsyncd.conf start##

uid = root

gid = root

use chroot = no

max connections = 200

timeout = 600

pid file = /var/run/rsyncd.pid

lock file = /var/run/rsync.lock

log file = /var/log/rsyncd.log

ignore errors

read only = false

list = false

hosts allow = 192.168.2.0/24

hosts deny = 0.0.0.0/32

auth users = rsync_backup

secrets file = /etc/rsync.password

########################################

[www]

comment = www by zhangjie 2013-06-13

path = /data0/www/www

########################################

[bbs]

comment = www by zhangjie 2013-06-13

path = /data0/www/bbs

########################################

[blog]

comment = www by zhangjie 2013-06-13

path = /data0/www/blog

#rsync_config_______________end

S2-server同上面的配置一样

2、建立rsync同步目录

mkdir /data0/www/{bbs,www,blog}/ -p

检查已建立好的目录

[root@S1-Server ~]# mkdir /data0/www/{bbs,www,blog}/ -p

[root@S1-Server ~]# tree /data0/www/

/data0/www/

|-- bbs

|-- blog

`-- www

3 directories, 0 files

3、配置相关权限认证

[root@S1-Server ~]# cat >/etc/rsync.password<<EOF

> rsync_backup:zhangjie

> EOF

[root@S1-Server ~]# cat /etc/rsync.password

rsync_backup:zhangjie

[root@S1-Server ~]# chmod 600 /etc/rsync.password

[root@S1-Server ~]# ll /etc/rsync.password

-rw------- 1 root root 22 Jun 13 00:19 /etc/rsync.password

4、开启rsync守护进程

[root@S1-Server ~]# rsync --daemon

[root@S1-Server ~]# ps -ef |grep rsync

root 5408 1 0 00:21 ? 00:00:00 rsync --daemon

root 5416 4004 0 00:21 pts/0 00:00:00 grep rsync

[root@S1-Server ~]# lsof -i :873

COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME

rsync 5408 root 3u IPv6 24598 TCP *:rsync (LISTEN)

rsync 5408 root 5u IPv4 24599 TCP *:rsync (LISTEN)

[root@S1-Server ~]# netstat -lnt |grep 873

tcp 0 0 0.0.0.0:873 0.0.0.0:* LISTEN

tcp 0 0 :::873 :::* LISTEN

5、设置开机自启动

[root@S1-Server ~]# echo "/usr/bin/rsync --daemon" >/etc/rc.local

[root@S1-Server ~]# tail -1 /etc/rc.local

/usr/bin/rsync --daemon

6、重启的命令

pkill rsync

rsync --daemon

ps -ef |grep rsync

7、在M-server上配置rsync客户端

[root@M-Server ~]# echo "zhangjie" >/etc/rsync.password

[root@M-Server ~]# cat /etc/rsync.password

zhangjie

[root@M-Server ~]# chmod 600 /etc/rsync.password

[root@M-Server ~]# ll /etc/rsync.password

-rw------- 1 root root 9 Jun 13 21:55 /etc/rsync.password

8、在M-server上手动测试rsync同步情况

1）分别创建待同步数据

[root@M-Server ~]# mkdir -p /data0/www/{www,bbs,blog}/

[root@M-Server ~]# touch /data0/www/www/www.log /data0/www/bbs/bbs.log /data0/www/blog/blog.log

[root@M-Server ~]# tree /data0/

/data0/

`-- www

|-- bbs

| `-- bbs.log

|-- blog

| `-- blog.log

`-- www

`-- www.log

4 directories, 3 files

2）执行同步命令

[root@M-Server ~]# rsync -avzP /data0/www/www/ [email protected]::www/ --password-file=/etc/rsync.password

sending incremental file list

www.log

0 100% 0.00kB/s 0:00:00 (xfer#1, to-check=0/2)

sent 77 bytes received 30 bytes 214.00 bytes/sec
