公司場景需求：離線伺服器上安裝一個nginx服務系統版本：CentOS 7.6

方法一:使用tar包，二進位制安裝 略

方法二：rpm方式安裝rpm包時，應該大家都遇到過缺少依賴包的問題，一個一個安裝依賴檔案，讓人頭疼。

這裡給大家介紹一種很方便的安裝方法使用yumdownloader命令離線安裝 nginx rpm服務包

1.首先找一個可以連線外網的伺服器

可以ping通百度域名，確定可以上外網[root@243-ceshi /]# ping www.baidu.comPING www.baidu.com icmp_seq=1 ttl=53 time=23.5 msicmp_seq=2 ttl=53 time=22.8 msicmp_seq=3 ttl=53 time=27.3 ms123456

2.安裝外掛

[root@localhost ~]# yum install yum-utils

3.建立一個存放rpm包的目錄

[root@localhost ~]# mkdir /rpm

4.下載nginx rpm相關檔案

[root@localhost rpm]# yumdownloader --resolve --destdir=/rpm  nginx

5.檢視rpm目錄下的檔案

[root@243-ceshi rpm]# lscentos-indexhtml-7-9.el7.centos.noarch.rpm  nginx-mod-http-image-filter-1.16.1-3.el7.x86_64.rpmgd-2.0.35-27.el7_9.x86_64.rpm               nginx-mod-http-perl-1.16.1-3.el7.x86_64.rpmgperftools-libs-2.6.1-1.el7.x86_64.rpm      nginx-mod-http-xslt-filter-1.16.1-3.el7.x86_64.rpmlibXpm-3.5.12-1.el7.x86_64.rpm              nginx-mod-mail-1.16.1-3.el7.x86_64.rpmnginx-1.16.1-3.el7.x86_64.rpm               nginx-mod-stream-1.16.1-3.el7.x86_64.rpmnginx-all-modules-1.16.1-3.el7.noarch.rpm   openssl11-libs-1.1.1g-2.el7.x86_64.rpmnginx-filesystem-1.16.1-3.el7.noarch.rpm12345678

nginx最新版本的相關依賴檔案全在都rpm目錄下了

6.把rpm目錄下檔案移到內網伺服器的/rpm目錄下

[root@243-ceshi /]# scp -r /rpm [email protected]:/[email protected]'s password:centos-indexhtml-7-9.el7.centos.noarch.rpm                                                100%   92KB  19.7MB/s   00:00gd-2.0.35-27.el7_9.x86_64.rpm                                                             100%  146KB  22.7MB/s   00:00gperftools-libs-2.6.1-1.el7.x86_64.rpm                                                    100%  272KB  26.2MB/s   00:00libXpm-3.5.12-1.el7.x86_64.rpm                                                            100%   55KB  17.6MB/s   00:00nginx-1.16.1-3.el7.x86_64.rpm                                                             100%  563KB  31.4MB/s   00:00nginx-all-modules-1.16.1-3.el7.noarch.rpm                                                 100%   20KB   8.2MB/s   00:00nginx-filesystem-1.16.1-3.el7.noarch.rpm                                                  100%   21KB   9.0MB/s   00:00nginx-mod-http-image-filter-1.16.1-3.el7.x86_64.rpm                                       100%   30KB  12.0MB/s   00:00nginx-mod-http-perl-1.16.1-3.el7.x86_64.rpm                                               100%   39KB  14.3MB/s   00:00nginx-mod-http-xslt-filter-1.16.1-3.el7.x86_64.rpm                                        100%   29KB  11.9MB/s   00:00nginx-mod-mail-1.16.1-3.el7.x86_64.rpm                                                    100%   57KB  16.6MB/s   00:00nginx-mod-stream-1.16.1-3.el7.x86_64.rpm                                                  100%   85KB  18.1MB/s   00:00openssl11-libs-1.1.1g-2.el7.x86_64.rpm                                                    100% 1485KB  40.6MB/s   00:00123456789101112131415

7.進入離線伺服器安裝

[root@localhost /]# cd /rpm[root@localhost rpm]# rpm -ivh * --nodeps --force警告：nginx-1.16.1-3.el7.x86_64.rpm: 頭V4 RSA/SHA256 Signature, 金鑰 ID 352c64e5: NOKEY準備中...                          ################################# [100%]正在升級/安裝...   1:openssl11-libs-1:1.1.1g-2.el7    ################################# [  8%]   2:nginx-filesystem-1:1.16.1-3.el7  ################################# [ 15%]   3:libXpm-3.5.12-1.el7              ################################# [ 23%]   4:gd-2.0.35-27.el7_9               ################################# [ 31%]   5:gperftools-libs-2.6.1-1.el7      ################################# [ 38%]   6:centos-indexhtml-7-9.el7.centos  ################################# [ 46%]   7:nginx-mod-http-image-filter-1:1.1################################# [ 54%]   8:nginx-mod-http-perl-1:1.16.1-3.el################################# [ 62%]   9:nginx-mod-http-xslt-filter-1:1.16################################# [ 69%]  10:nginx-mod-mail-1:1.16.1-3.el7    ################################# [ 77%]  11:nginx-all-modules-1:1.16.1-3.el7 ################################# [ 85%]  12:nginx-1:1.16.1-3.el7             ################################# [ 92%]  13:nginx-mod-stream-1:1.16.1-3.el7  ################################# [100%]12345678910111213141516171819

8.啟動nginx服務
