其实云计算的学习和研究也有一段时间了,虽然是非正式的。使用云服务器的话,机会其实不多。九月的时候曾经在AWS的Win2003上工作了一小段时间,感觉是非常不稳定,老是连不上。
今天看到园子里提供代金券,就领取了。想着试用一个月,可最低配置的价格需要89,刚好差一块钱,可恶啊。
看下广告,答题晒weibo可以再领代金券,那就瞎答试试,结果得了70分,这下够了,买了130的配置。
配置:1核处理器 1G 1Mbps 容量60GB CentOS 6.2 64位
开始不知道怎么登陆,查了一下才知道用 root。修改密码,重启,登陆,OK。
[root@AY1210300338513bb3855 ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/xvda1 20G 529M 20G 3% / tmpfs 498M 0 498M 0% /dev/shm
怎么只有20G,难道坑爹。用 fdisk 看看,数据盘还没格式化和挂载。
Disk /dev/xvda: 21.5 GB, 21474836480 bytes 255 heads, 63 sectors/track, 2610 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/xvda1 * 1 2550 20480000 83 Linux /dev/xvda2 2550 2611 490496 82 Linux swap / Solaris Disk /dev/xvdb: 42.9 GB, 42949672960 bytes 255 heads, 63 sectors/track, 5221 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/xvdb doesn't contain a valid partition table
操作还是熟悉的吧,用 cfdisk 分区,fdisk太难用了,然后格式化。

这下容量看起来正常了。
尝试安装编译工具,可惜失败了,无法满足依赖,出问题的包是 kernel-header。后来才知道需要修改yum.conf,注释掉kernel这行。
[main] cachedir=/var/cache/yum/$basearch/$releasever keepcache=0 debuglevel=2 logfile=/var/log/yum.log exactarch=1 obsoletes=1 gpgcheck=1 plugins=1 #exclude=kernel*
重新安装试试看,没有问题。
