在centos7中安裝docker的相關環境
環境簡介 作業系統:CentOS是最小化安裝 機器的ip:192.168.0.205
---------------開始安裝------------------------------ 修改機器名稱 hostnamectl --static set-hostname node205
由於顯示有亂碼，在ssh客戶端上臨時設定顯示字元級 export LANG=zh_CN.gbk
檢查內網是否通，ping 204 [[email protected] ~]# ping 192.168.0.204 PING 192.168.0.204 (192.168.0.204) 56(84) bytes of data. 64 bytes from 192.168.0.204: icmp_seq=1 ttl=64 time=0.120 ms 64 bytes from 192.168.0.204: icmp_seq=2 ttl=64 time=0.116 ms 64 bytes from 192.168.0.204: icmp_seq=3 ttl=64 time=0.123 ms ^C — 192.168.0.204 ping statistics — 3 packets transmitted, 3 received, 0% packet loss, time 1999ms rtt min/avg/max/mdev = 0.116/0.119/0.123/0.012 ms
檢查外網是否通 [[email protected] ~]# ping www.baidu.com ping: www.baidu.com: 未知的名稱或服務
以下需要解決連線外網
檢視當前網絡卡資訊 [[email protected] ~]# nmcli connection show NAME UUID TYPE DEVICE ens160 8b7efc2d-d2af-4fce-a41b-c8eaf0a237e5 ethernet ens160 證明外網通過ens160連線。
檢查網絡卡的連線狀態 nmcli connection show
修改ens160的連線配置檔案 網絡卡的配置檔案放在/etc/sysconfig/network-scripts目錄中ifcfg-ens160 修改這個檔案 TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=static DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no IPV6_ADDR_GEN_MODE=stable-privacy NAME=ens160 UUID=8b7efc2d-d2af-4fce-a41b-c8eaf0a237e5 DEVICE=ens160 ONBOOT=yes IPADDR0=192.168.0.205 PREFIXO0=24 GATEWAY0=192.168.0.1 DNS1=8.8.8.8 DNS2=8.8.4.4
ZONE=public
完成更新後重新啟動 reboot
通過ssh終端連線到205伺服器 檢查外網是否暢通 [[email protected] ~]# ping www.baidu.com PING www.baidu.com (14.215.177.38) 56(84) bytes of data. 64 bytes from 14.215.177.38 (14.215.177.38): icmp_seq=1 ttl=54 time=19.2 ms 64 bytes from 14.215.177.38 (14.215.177.38): icmp_seq=2 ttl=54 time=19.0 ms
[[email protected] ~]# ifconfig -bash: ifconfig: 未找到命令 [[email protected] ~]# echo $PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin 證明沒有安裝ifconfig，需要連線安裝
安裝ifconfig yum install net-tools.x86_64
安裝完成後檢視資訊 [[email protected] ~]# ifconfig ens160: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.0.205 netmask 255.255.255.0 broadcast 192.168.0.255 inet6 fe80::d792:fa0f:7857:6cd7 prefixlen 64 scopeid 0x20 ether 00:50:56:ae:c3:af txqueuelen 1000 (Ethernet) RX packets 10998 bytes 13884873 (13.2 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 9129 bytes 819355 (800.1 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

機器的網路相關配置完成，以下安裝Docker相關 sudo yum remove docker docker-common docker-selinux docker-engine 刪除舊版本 [[email protected] ~]# sudo yum remove docker docker-common docker-selinux docker-engine
安裝需要的軟體包yum-util 提供yum-config-manager功能，另外兩個是devicemapper驅動依賴的 yum install -y yum-utils device-mapper-persistent-data lvm2
建立元資料快取 sudo yum makecache fast
安裝docker latest版本 sudo yum -y install docker-ce
