三、检查HESC环境
1.检查系统版本
[root@server-01 ~]# cat /etc/os-release
NAME="CentOS Linux"
VERSION="8 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="8"
PLATFORM_ID="platform:el8"
PRETTY_NAME="CentOS Linux 8 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:8"
HOME_URL="https://www.centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"
CENTOS_MANTISBT_PROJECT="CentOS-8"
CENTOS_MANTISBT_PROJECT_VERSION="8"
REDHAT_SUPPORT_PRODUCT="centos"
REDHAT_SUPPORT_PRODUCT_VERSION="8"
aaa
2.检查VPC本地IP地址
[root@server-01 ~]# ifconfig eth0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.200.150 netmask 255.255.255.0 broadcast 192.168.200.255
inet6 fe80::f816:3eff:fe26:7b4 prefixlen 64 scopeid 0x20<link>
ether fa:16:3e:26:07:b4 txqueuelen 1000 (Ethernet)
RX packets 7806451 bytes 4883098416 (4.5 GiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 10812338 bytes 5026213960 (4.6 GiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
四、配置yum仓库
1.备份yum仓库
[root@server-01 yum.repos.d]# pwd
/etc/yum.repos.d
[root@server-01 yum.repos.d]# cp -a ./* /tmp/
2.配置阿里仓库源
[root@server-01 yum.repos.d]# curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 2495 100 2495 0 0 13708 0 --:--:-- --:--:-- --:--:-- 13708
3.配置epel源
yum install -y https://mirrors.aliyun.com/epel/epel-release-latest-8.noarch.rpm #安装 epel 配置包
[root@server-01 yum.repos.d]# sed -i 's|^#baseurl=https://download.example/pub|baseurl=https://mirrors.aliyun.com|' /etc/yum.repos.d/epel* # ）将 repo 配置中的地址替换为阿里云镜像站地址
[root@server-01 yum.repos.d]# sed -i 's|^metalink|#metalink|' /etc/yum.repos.d/epel*
4.配置docker源
①安装系统工具
yum install -y yum-utils device-mapper-persistent-data lvm2
②配置docker源
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo
5.生成缓存
[root@server-01 yum.repos.d]# yum makecache
CentOS-8.5.2111 - Base - mirrors.aliyun.com 48 kB/s | 3.9 kB 00:00
CentOS-8.5.2111 - Extras - mirrors.aliyun.com 19 kB/s | 1.5 kB 00:00
CentOS-8.5.2111 - AppStream - mirrors.aliyun.com 33 kB/s | 4.3 kB 00:00
Docker CE Stable - x86_64 22 kB/s | 3.5 kB 00:00
Extra Packages for Enterprise Linux Modular 8 - x86_64 25 kB/s | 3.0 kB 00:00
Extra Packages for Enterprise Linux 8 - x86_64 47 kB/s | 4.7 kB 00:00
Metadata cache created.
6.列出yum源
