樹莓派centos7系統安裝配置

目錄1.燒錄系統
2.配置自動連接wifi
3.擴展內存
4.更換yum源
5.docker安裝
1.燒錄系統
Centos ARM芯片的版本下載地址：http://mirror.centos.org/altarch/7/isos/armhfp/

首先，格式化內存卡，然後將下載的Centos系統解壓，寫入系統到SD卡中，最後將SD卡插入樹莓派。
2.配置自動連接wifi
首先，進入vi /etc/wpa_supplicant/wpa_supplicant.conf 文件中配置：

network={
 ssid="無線網名稱"
 psk="密碼"
 priority=10
}

然後，連接wifi，配置好後每次啟動自動連接無線網。

nmcli d wifi connect 無線網名稱 password '密碼'

3.擴展內存

rootfs-expand

4.更換yum源
首先，將/etc/yum.repos.d/ 文件夾下的文件除了CentOS-Base.repo 都刪掉

# 1. 編輯CentOS-Base.repo
[root@centos-rpi3 ~]# vi /etc/yum.repos.d/CentOS-Base.repo
# 2. 不會用vi的朋友別亂動，可以按著d鍵不松手，即可清空整個文件
# 會的朋友直接清空它就行了
# 3. 複制下面的文字到這個文件中，使用putty的話就是在windows下複制，然後再putty中右鍵就可以粘貼
# 4. 按Esc，然後輸入引號內的內容：“:wq”注意英文符號，隨後會退出vi
# 5. 執行下面兩句代碼：
yum clean all
yum makecache

CentOS-Base.repo 文件內容

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
