UBUntu 軟體 源配置方法

標籤：ubuntu 下實現產品自動更新功能

    最近公司產品需要增加一個功能，就是版本自動更新，使用apt-get 實現。apt-get 軟體源配置的方法，參見本人資源裡的共用。下面是代碼中作為升級的一部分。 

FILE *fp;char buffer[256];char source_ok[] = "Reading package lists...";if(0 > system("mv -f /etc/apt/sources.list /etc/apt/sources.list.upgrade"))printf("cldUp backup old source list error!\n");fp=fopen("/etc/apt/sources.list","w+");if(0 == fp)goto update_done;fprintf(fp,"deb http://%s/apt %s %s", source_addr, source_dir, source_ver);printf("\ndeb http://%s/apt %s %s\n", source_addr, source_dir, source_ver);fclose(fp);fp=popen("apt-get update 2>&1","r");while(!feof(fp)){if(0 == fgets(buffer,sizeof(buffer),fp))break;printf("%s",buffer);                fflush(stdout);if(strstr(buffer,"Failed")){trace_log(buffer);                        printf("scan failed and exit\n");        goto update_done;}if(strstr(buffer,source_ok)){trace_log(buffer);                                                printf("scan sourceok  and exit\n");break;}}pclose(fp);fp=popen("apt-get -y --force-yes install ssh 2>&1","r");while(!feof(fp)){if(0 == fgets(buffer,sizeof(buffer),fp))break;printf("%s",buffer);                if(strstr(buffer,"1 upgraded")){                //save the upgrade info                 b_upgrade_success = true;trace_log(buffer);                       }        }pclose(fp);        if(b_upgrade_success)        {               b_upgrade_success = 0;                       }update_done:if(0 > system("mv -f /etc/apt/sources.list.upgrade /etc/apt/sources.list"))printf("restore source list error!\n");

初步測試沒有什麼問題。
