半夜起來看世界杯，沒啥激情，但是又怕錯誤意大利和英格蘭的比賽，就看了rhel7
相關新功能的介紹。
安裝還算順利，安裝的界面比以前簡潔的多，很清爽，分類很是明确。
有些奇怪的是，我安裝的時候，怕有些基礎的包沒有裝上去，是以標明了mini和web的類型，結果還是有些基礎的包沒有安裝，比如 ifconfig 。
虛拟機的網卡，被識别為ens，有意思。
yum groupinstall base
這樣的話，就可以把一些基礎的包打上。可以正常的時候ifconfig lsof 。
[rhel-iso]
baseurl=file:///mnt/
enabled=1
系統的分區預設是xfs格式，當然你還是可以用ext3，ext4的
[root@localhost ~]# df -t
檔案系統 類型 1k-blocks 已用 可用 已用% 挂載點
/dev/mapper/rhel-root xfs 39262208 3591304 35670904 10% /
devtmpfs devtmpfs 500772 0 500772 0% /dev

/dev/sda1 xfs 494940 95444 399496 20% /boot
發現rhel7的開發軟體版本不低。
[root@localhost ~]#
[root@localhost ~]# python -v
python 2.7.5
java version "1.7.0_45"
openjdk runtime environment (rhel-2.4.3.4.el7-x86_64 u45-b15)
openjdk 64-bit server vm (build 24.45-b08, mixed mode)
[root@localhost ~]# perl -v
this is perl 5, version 16, subversion 3 (v5.16.3) built for x86_64-linux-thread-multi
(with 24 registered patches, see perl -v for more detail)
想安裝pip但是iso沒有python-pip這個包。rhel7的官方源又打不開，郁悶。本來打算用epel6試試，用不了，到epel官網一瞅。epel居然已經有對于rhel7的源了。
