如何在沒有互聯網連接的情況下在CentOs7上安裝Nginx并獲得root權限？-有解無憂

我需要在沒有互聯網連接的目標上安裝 Nginx，如何在離線模式下安裝所有依賴項的 Nginx？提前感謝您的回答。

我最近經歷了這個程序，這對我在 centos7 上有用：

您需要一個在線 Linux 服務器來下載依賴項。您可以使用虛擬機或其他任何東西。在您的在線服務器上創建一個 .sh 檔案并在其中復制下面的腳本。（我將其命名為 download_dependencies）

#!/bin/bash
# This script is used to fetch external packages that are not available in standard Linux distribution

# Example: ./fetch-external-dependencies ubuntu18.04
# Script will create nms-dependencies-ubuntu18.04.tar.gz in local directory which can be copied
# into target machine and packages inside can be installed manually

set -eo pipefail

# current dir
PACKAGE_PATH="."

mkdir -p $PACKAGE_PATH

download_packages() {
    local target_distribution=$1

    echo "Downloading Clickhouse signing keys"

if [ -z $target_distribution ]; then
    echo "Usage: $0 target_distribution"
    echo "Supported target distributions: ${!CLICKHOUSE_REPO[@]}"
    exit 1

# check if target distribution is supported

if [ -z ${CLICKHOUSE_REPO[$target_distribution]} ]; then
    echo "Target distribution is not supported."
    echo "Supported distributions: ${!CLICKHOUSE_REPO[@]}"
    exit 1
fi

download_packages "${target_distribution}"

然后在包含 download_dependencies.sh 的同一目錄中運行以下命令：

download_dependencies.sh <your linux version>

就我而言，我在下面運行了代碼（將其留空以查看選項）：

download_dependencies.sh centos7

它應該開始下載，完成后您應該會在您的目錄中看到 nms-dependencies-rhel7.tar.gz。 將該檔案（.tar.gz）復制到您的離線目標。

現在在您的目標機器上，轉到您復制檔案的目錄并運行以下代碼：

tar -zxvf nms-dependencies-rhel7.tar.gz
sudo yum install *.rpm

安裝后你可以使用 systemctl 啟動 nginx：

sudo systemctl start clickhouse-server
sudo systemctl start nginx

您的 nginx 服務現在必須正在運行！

您可以在另一個系統中下載 tar 檔案并復制
