dubbo微服务shell启动脚本

在linux环境下部署dubbo并启动服务，假设现在要发布一个用户管理微服务到测试服务器，指定端口：8081，模块名称：user，

shell脚本如下（app-8081-user.sh）：

#!/bin/bash
# This shell script takes care of starting and stopping program.
#
# chkconfig: - 90 10
# processname: app-8081-user

# Source function library.
. /etc/rc.d/init.d/functions

ttl_version="2.1.0"
prog="app-8081-user"
prog_keyword="app-8081-user"
prog_port="8081"
prog_dir=/data/app-8081-user
prog_log_dir=/log/gc/app-8081-user
prog_std_log="/dev/null"
prog_gc_log=$prog_log_dir/gc.log

[ -d $prog_dir ] || exit 1

RETVAL=0
