簡單的linux service（linux服務）編寫，運行示例

1.寫一個簡單小程序

#include<stdio.h>
#include<stdlib.h>

int main(int argc,char **argv)
{
　　while(1)
　　{
　　　　printf("hello world\n");
　　　　sleep(2);//2s
　　}
}

 

 2.gcc編譯

gcc -o hello hello.c

 生成hello

./hello

 測試，ok！

 

3.在/etc/init.d/目錄下生成hello.sh腳本

hello.sh:

#!/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.更改腳本文件屬性

chmod +x hello.sh

 

5.運行

（1）啟動：

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

（2）停止：

root@localhost:/home/yao/projects# service hello.sh stop
stop hello
stop hello ok!

（3）重啟：

root@localhost:/etc/init.d# service hello.sh restart
stop hello
stop hello ok!
start hello
hello world
hello world

 6.over!
