Fedora 16设置开机自启动程序与Ubuntu的区别

Ubuntu设置开机自启动脚本的方法是：修改/etc/init.d/rc.local这个文件，添加需要启动的程序即可，相关函数如下：

void SetSysAutoBoot()
{
    char path[] = {};
    int ret = ;

    ret = readlink("/proc/self/exe",path,sizeof(path));

    if((ret >  )&& (ret < sizeof(path)))
    {
        printf("system path  :  %s\n",path);
    }

    char* fileName = "/etc/init.d/rc.local";
    int fileLen = GetFileSize(fileName);

    FILE * fp = fopen(fileName,"r+");
    char* buf;

    buf = (char*)malloc(fileLen*);
    char* tempBuf = buf;

    if(fp == NULL)
    {
        return;
    }

    int flag = ;

    while(!feof(fp))
    {
        tempBuf = fgets(buf,fileLen,fp);

        if(tempBuf != buf)
        {
            break;
        }

        //exist
        if(strstr(tempBuf,path) != )
        {
            //
            flag = ;
        }

    }

    fclose(fp);

    //not exist
    if( == flag)
    {
        char buf[];
        sprintf(buf,"echo \"%s &\" >> /etc/init.d/rc.local\n",path);
        printf(buf);
        system(buf);
    }

    free(buf);
}

但是FC16系统并不系统自带/etc/init.d/rc.local这个文件，于是我们就要自作做一些配置了。

1. 首先写一个测试脚本，

touch /etc/rc.d/rc.local

这个文件的内容是:

#!/bin/sh
date >> /IpMonitor/test.txt
/IpMonitor/IpMonitor-Server &

设置可执行权限:

chmod 777 /etc/rc.d/rc.local

设置软链接：

ln -s /etc/rc.d/rc.local /etc/rc.local

2. 开启rc-local.service

systemctl start rc-local.service

3. reboot即可看到效果了。
