rsync xinetd (文件同步策略)
rsync设置:####
1.打开rsync控制开关(修改文件 /etc/default/rsync)
2.sudo cp /usr/share/doc/rsync/examples/rsyncd.conf /etc
3.修改 /etcrsyncd.conf
4.服务重启
xinetd###
extended internet daemon 网络守护进程服务程序###
service rsync
{
disable = no
socket_type = stream
wait = no
user = root
server = /usr/bin/rsync
server_args = --daemon
log_on_failure += USERID
}
前提:关掉防火墙
1.自定义一个服务(别忘了要编译):
[root@linuxclient Desktop]# cat /tmp/hello.c
#include<stdio.h>
int main(){
printf("hello,buddy!\n");
return 0;
}
2.在xinetd.d里面新添加一个文件,名叫hello_server
[root@linuxclient Desktop]# cat /etc/xinetd.d/hello_server
#cp telnet hello
#vim hello
service hello_server
{
disable = no
flags = REUSE
socket_type = stream
wait = no
user = root
server = /tmp/hello
log_on_failure+=USERID
port = 9015
}
3.将新建的服务加到/etc/services里面去
[root@linuxclient Desktop]# cat /etc/services |grep 9015
hello_server 9015/tcp
4.重启xinetd服务
5.查看9015是否开启
[root@linuxclient Desktop]# netstat -tnlp|grep 9015
tcp 0 0 :::9015 :::* LISTEN 2254/xinetd
6.测试:
[root@linuxserver Desktop]# telnet 192.168.70.150 9015
Trying 192.168.70.150...
Connected to 192.168.70.150 (192.168.70.150).

hello,buddy!
