[心得]Virtualbox下安裝virtualbox tools

1.安裝virtualbox所需要的套件.

yum install dkms binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-pae-devel -y

2.建立資料夾.

mkdir /media/cdrom

3.掛載光碟機.

mount /dev/sr0 /media/cdrom

4.切換到光碟機並執行virtual box tools sh.

cd /media/cdrom

sh ./VBoxLinuxAdditions.run

5.重新開機.

reboot

[Docker心得]網卡混亂模式設定篇

首先本次操作是在CentOS7 64bit上,反正早晚都要熟悉新版指令不如提早開始.

Promiscuous是混雜模式，是指對目的硬體位址不加任何檢查，全部接收的工作模式 .

1.之前的ifconfig -a這指令在CentOS7上已經改成下列指令
$ip a
懷舊的朋友可以下:sudo yum -y install net-tools安裝完後即可下達ifconfig,提醒之後的CentOS版也不會有ifconfig的指令了早點習慣新版.
指令下完後看一下docker0這個虛擬的網路介面,注意""內的文字,這裏是標注提醒不會真的顯示在你的畫面上.
3: docker0: <"NO-CARRIER,BROADCAST,MULTICAST,UP"> mtu 1500 qdisc noqueue state DOWN

2.把docker的虛擬網路卡停止
ip link set dev docker0 down






3.再次觀察docker的虛擬網路卡的變化
ip a
3: docker0: <"BROADCAST,MULTICAST"> mtu 1500 qdisc noqueue state DOWN








4.查看自己設備上網卡名稱
vi /etc/sysconfig/network-scripts/ifcfg-<host_network>


5.啟動混亂模式
ip link set eth0 promisc on

6.觀察是否正確啟動
ip a
2:<host_network>: <“BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP”> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:50:56:81:22:12 brd ff:ff:ff:ff:ff:ff

基本上以上完成就能ping到docker0這張虛擬網卡了.
再來的Docker橋接跟固定IP設定就另開一篇來討論了,目前也卡住在固定IP設定.

[Docker心得]在Centos6與Centos7安裝的差異比較

到目前為止,如果使用Centos7安裝Docker記得images使用cnetos6的版本會比較好一點,光卡在systemctl上就能卡很久了,待續.

1.Centos6安裝步驟

1.1首先要安裝上EPEL後才能安裝Docker,所以6以後的版本就不建議玩Docker了.

sudo wget http://download.fedoraproject.org/pub/epel/4/x86_64/epel-release-4-10.noarch.rpm

1.2下載完RPM檔後,就安裝了.

sudo rpm -ivh epel-release-4-10.noarch.rpm

1.3安裝完RPM檔後一定要更新.

sudo yum repolist

Centos6安裝EPEL參考連結 http://www.tecmint.com/how-to-enable-epel-repository-for-rhel-centos-6-5/

1.4接著移除Centos6上的docker(這步必要不管是剛剛裝完OS,或是舊有版本安裝docker).

sudo yum -y remove docker

1.5安裝Docker.

sudo yum install docker-io

1.6啟動Docker服務.

sudo service docker start

1.7設定Docker服務常駐.

sudo chkconfig docker on

Docker官方安裝參考連結 https://docs.docker.com/installation/centos/

2.Centos7安裝步驟

2.1安裝Docker.

sudo yum -y install docker docker-registry

2.2常駐Docker服務.

sudo systemctl enable docker.service

2.3啟動Docker.

sudo systemctl start docker.service

Centos7三步驟就收工,當然記得安裝完後確認一下Docker的版本.

sudo docker version

如果想玩目前最新支援ipv6的1.5版,記得更新.

sudo systemctl stop docker 

sudo wget https://get.docker.com/builds/Linux/x86_64/docker-latest -O /usr/bin/docker

sudo systemctl start docker

[心得]Docker Network Configuration

建立自訂橋接網卡IP
1.停止Docker服務並移除預設 docker0上設定.
sudo systemctl stop docker
sudo ip link set dev docker0 down
sudo brctl delbr docker0
sudo iptables -t nat -F POSTROUTING
2.建立自訂橋接網卡
sudo brctl addbr bridge0
sudo ip addr add 192.168.5.1/24 dev bridge0
sudo ip link set dev bridge0 up
3.確認setp2設定
ip addr show bridge0
**使用Ubuntu當Base OS時下列指令要下:
$ echo 'DOCKER_OPTS="-b=bridge0"' >> /etc/default/docker
sudo systemctl start docker
4.最後確認
sudo iptables -t nat -L -n
