//2s
}
}

2.gcc编译
|
1
|
gcc -o hello hello.c
|
生成hello

#!/bin/bash
SERVERNAME=
"hello"
start()
{
echo
"start $SERVERNAME"
/home/yao/projects/
$SERVERNAME
echo
"start $SERVERNAME ok!"
exit
0;
}
stop()
{
echo
"stop $SERVERNAME"
killall $SERVERNAME
echo
"stop $SERVERNAME ok!"
}
case
"$1"
in
start)
start
;;
stop)
stop
;;
restart)
stop
start
;;
*)
echo
"usage: $0 start|stop|restart"
exit
0;
esac
exit
|
4.更改脚本文件属性
|
1
|
chmod
+x hello.sh
|
5.运行
（1）启动：
|

|
root@localhost:
/home/yao/projects
# service hello.sh start
start hello
hello world
