1.1.2 设置主机名

hostnamectl set-hostname ha01.example.local
hostnamectl set-hostname ha02.example.local
hostnamectl set-hostname harbor01.example.local
hostnamectl set-hostname harbor02.example.local
hostnamectl set-hostname client.example.local

1.1.3 配置镜像源

Rocky 8和9：

MIRROR=mirrors.sjtug.sjtu.edu.cn
sed -i.bak -e 's|^mirrorlist=|#mirrorlist=|g' -e 's|^#baseurl=http://dl.rockylinux.org/$contentdir|baseurl=https://'${MIRROR}'/rocky|g' /etc/yum.repos.d/[Rr]ocky*.repodnf clean all && dnf makecache

CentOS Stream 9：

cat update_mirror.pl
#!/usr/bin/perluse strict;
use warnings;
use autodie;# 要修改镜像源，请去修改url变量！
my $url = 'mirrors.aliyun.com';
my $mirrors = "https://$url/centos-stream";if (@ARGV < 1) {die "Usage: $0 <filename1> <filename2> ...\n";
}while (my $filename = shift @ARGV) {my $backup_filename = $filename . '.bak';rename $filename, $backup_filename;open my $input, "<", $backup_filename;open my $output, ">", $filename;while (<$input>) {s/^metalink/# metalink/;if (m/^name/) {my (undef, $repo, $arch) = split /-/;$repo =~ s/^\s+|\s+$//g;($arch = defined $arch ? lc($arch) : '') =~ s/^\s+|\s+$//g;if ($repo =~ /^Extras/) {$_ .= "baseurl=${mirrors}/SIGs/\$releasever-stream/extras" . ($arch eq 'source' ? "/${arch}/" : "/\$basearch/") . "extras-common\n";} else {$_ .= "baseurl=${mirrors}/\$releasever-stream/$repo" . ($arch eq 'source' ? "/" : "/\$basearch/") . ($arch ne '' ? "${arch}/tree/" : "os") . "\n";}}print $output $_;}
}rpm -q perl &> /dev/null || { echo -e "\\033[01;31m "安装perl工具,请稍等..."\033[0m";yum -y install perl ; }perl ./update_mirror.pl /etc/yum.repos.d/centos*.repodnf clean all && dnf makecache

CentOS Stream 8：

MIRROR=mirrors.aliyun.com
sed -i.bak -e 's|^mirrorlist=|#mirrorlist=|g' -e 's|^#baseurl=http://mirror.centos.org/$contentdir|baseurl=https://'${MIRROR}'/centos|g' /etc/yum.repos.d/CentOS-*.repodnf clean all && dnf makecache

CentOS 7：

MIRROR=mirrors.aliyun.com
sed -i.bak -e 's|^mirrorlist=|#mirrorlist=|g' -e 's|^#baseurl=http://mirror.centos.org|baseurl=https://'${MIRROR}'|g' /etc/yum.repos.d/CentOS-*.repoyum clean all && yum makecache

Ubuntu 22.04和20.04：

MIRROR=mirrors.aliyun.com
OLD_MIRROR=`sed -rn "s@^deb http(.*)://(.*)/ubuntu/? $(lsb_release -cs) main.*@\2@p" /etc/apt/sources.list`sed -i.bak 's/'${OLD_MIRROR}'/'${MIRROR}'/g' /etc/apt/sources.listapt update

Ubuntu 18.04：

MIRROR=mirrors.aliyun.com
OLD_MIRROR=`sed -rn "s@^deb http(.*)://(.*)/ubuntu/? $(lsb_release -cs) main.*@\2@p" /etc/apt/sources.list`sed -i.bak 's/'${OLD_MIRROR}'/'${MIRROR}'/g' /etc/apt/sources.listSECURITY_MIRROR=`sed -rn "s@^deb http(.*)://(.*)/ubuntu $(lsb_release -cs)-security main.*@\2@p" /etc/apt/sources.list`sed -i.bak 's/'${SECURITY_MIRROR}'/'${MIRROR}'/g' /etc/apt/sources.listapt update

1.1.4 关闭防火墙

# Rocky和CentOS
systemctl disable --now firewalld# CentOS 7
systemctl disable --now NetworkManager# Ubuntu
systemctl disable --now ufw

1.1.5 禁用SELinux

#CentOS
setenforce 0
sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config#Ubuntu
Ubuntu没有安装SELinux，不用设置

1.1.6 设置时区

ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
echo 'Asia/Shanghai' >/etc/timezone#Ubuntu还要设置下面内容
cat >> /etc/default/locale <<-EOF
LC_TIME=en_DK.UTF-8
EOF

1.2 安装 Nginx

1.6 在docker客户端验证

在172.31.0.8的Rocky 8的主机上无需登录，即可下载镜像

首先要主机初始化和安装docker
