## Rsync 服务器端脚本
## 脚本说明：如果系统中已存在rsyncd.conf文件，在该文件后面追加配置项，
##			 如果不存在，则新建该文件，并添加配置项
## 操作说明：执行过本脚本以后，需要做客户端配置

##项目名
read -p "The Project name:[Not username]" PRO_NAME

##客户端IP
read -p "The Client IP:" PRO_BACK_IP

##项目存放位置(类似/opt/appl/project)
read -p "The Project path:[/opt/appl/project]" PRO_PATH

##项目用户UID
PRO_UID=`stat -c %u $PRO_PATH`

##配置文件
RSYNC_CFG=/etc/rsyncd.conf

##密码文件
PASS_CFG=/etc/rsyncd.pass

yum -y install rsync xinetd > /dev/null 2>&1

##存在rsyncd.conf文件
