Linux下rpm倉庫搭建
1、概念html
1.rpm是什麼？在幫助文檔裏咱們能夠看到，rpm的名字是rpm package manage 的縮寫， 從名字上看就能夠知道rpm就是一個包管理工具。簡單說rpm包就是把一些程序編譯成二進制，和一些配置文件以及幫助文檔等一些程序所依賴庫打包在一塊兒，這樣造成的一個包。rpm大大的簡化用戶在Linux上安裝軟件的複雜度。前端
2.rpm倉庫是什麼？從字面理解,倉庫就是集中存放東西的地方，一樣rpm倉庫就是集中存放rpm包的一個地方。這裏說的‘地方’就是服務器。把不少rpm包放在一個特定的服務器的特定目錄裏， 再由好比http、nfs、ftp、file這些協議是用來提供給其餘服務器下載rpm包的服務器，咱們把這樣的服務器稱爲rpm倉庫服務器。java
3.yum是什麼？yum是Yellowdog Updater Modified 的縮寫，翻譯過來就是Yellowdog 更新修改，徹底沒有搞懂這個翻譯究竟是什麼意思，查下百度百科吧！yum是一個在Fedora、Redhat以及CentOS中的shell前端軟件包管理器。基於rpm包管理，可以從指定的服務器自下載rpm包而且安裝，能夠自動處理包依賴關係，而且可以一次安裝全部所依賴的軟件包，無需頻繁的一次次下載安裝。看了百度的解釋，咱們應該知道yum是什麼了吧！簡單說就是基於rpm包的前端管理工具，它能夠幫咱們解決包與包的依賴關係。web
4.yum的工做機制。yum是c/s架構的工做機制，服務端提供rpm倉庫，客戶端根據服務端提供的倉庫，經過特定協議去服務端下載所須要的包來進行安裝。第一次去服務端，它會把服務端的倉庫元數據緩存到本地，這樣就不須要每次下載都去服務端查詢。所謂倉庫的元數據就是記錄着該倉庫有哪些包，包名，包與包的依賴關係等一些數據。每次要裝包的時候，yum會去看看本地緩存的元數據，有沒有須要的包的信息，若是有，他們會把相應的包以及所依賴的包一併去服務端下載下來，一併安裝。sql
2、倉庫的搭建shell
瞭解了以上的基本概念，下面咱們開始來搭建rpm倉庫吧centos
1.建立目錄結構緩存
[root@test ~]$mkdir -pv /rpm/centos/{6,7}/os/x86_64 mkdir: created directory `/rpm' mkdir: created directory `/rpm/centos' mkdir: created directory `/rpm/centos/6' mkdir: created directory `/rpm/centos/6/os' mkdir: created directory `/rpm/centos/6/os/x86_64' mkdir: created directory `/rpm/centos/7' mkdir: created directory `/rpm/centos/7/os' mkdir: created directory `/rpm/centos/7/os/x86_64'
說明：本次實驗是在centos6或centos7平臺架構是x86_64的系統上來建立的目錄tomcat
2.上傳包服務器
[root@test ~]$cd /rpm/centos/6/os/x86_64/ [root@test x86_64]$pwd /rpm/centos/6/os/x86_64 [root@test x86_64]$mv /root/samba-3.6.23-41.el6.x86_64.rpm /root/vsftpd-2.2.2-24.el6.x86_64.rpm . [root@test x86_64]$cd ../../../7/os/x86_64/ [root@test x86_64]$pwd /rpm/centos/7/os/x86_64 [root@test x86_64]$mv /root/tomcat-7.0.76-2.el7.noarch.rpm /root/samba-4.6.2-8.el7.x86_64.rpm .
說明： 上傳了4個包，在/rpm/centos/6/os/x86_64/ 放了samba-3.6.23-41.el6.x86_64.rpm和vsftpd-2.2.2-24.el6.x86_64.rpm兩個包，在/rpm/centos/7/os/x86_64放了samba-4.6.2-8.el7.x86_64.rpm和tomcat-7.0.76-2.el7.noarch.rpm兩個包，本人先是把包傳到服務器，而後移動到相應的目錄裏。
3.建立元數據
首先要檢查本身的服務器有沒有裝createrepo這個工具
[root@test x86_64]$rpm -q createrepo
package createrepo is not installed
若是沒有就安裝
[root@test x86_64]$yum install -y createrepo
建立倉庫元數據
[root@test ~]$createrepo /rpm/centos/6/os/x86_64/ Spawning worker 0 with 2 pkgs Workers Finished Gathering worker results Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete [root@test ~]$createrepo /rpm/centos/7/os/x86_64/ Spawning worker 0 with 2 pkgs Workers Finished Gathering worker results Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete [root@test ~]$ll /rpm/centos/6/os/x86_64/ total 5368 drwxr-xr-x 2 root root 4096 Sep 8 16:18 repodata -rw-r--r--+ 1 root root 5331428 Sep 8 16:02 samba-3.6.23-41.el6.x86_64.rpm -rw-r--r--+ 1 root root 159332 Sep 8 16:02 vsftpd-2.2.2-24.el6.x86_64.rpm [root@test ~]$ll /rpm/centos/7/os/x86_64/ total 732 drwxr-xr-x 2 root root 4096 Sep 8 16:18 repodata -rw-r--r--+ 1 root root 647996 Sep 8 16:04 samba-4.6.2-8.el7.x86_64.rpm -rw-r--r--+ 1 root root 91820 Sep 8 16:04 tomcat-7.0.76-2.el7.noarch.rpm
說明：能夠看到在兩個倉庫下各自生成了一個repodata的目錄，這裏說一下，要肯定倉庫的路徑就是要看repodata這個目錄的父目錄是什麼，repodata目錄所在的父目錄就是倉庫的路徑。
4.在客戶端編寫repo配置文件
[root@test ~]$cd /etc/yum.repos.d/ [root@test yum.repos.d]$ls CentOS-Base.repo CentOS-Debuginfo.repo CentOS-fasttrack.repo CentOS-Media.repo CentOS-Vault.repo epel.repo epel-testing.repo [root@test yum.repos.d]$mkdir repo_bak [root@test yum.repos.d]$mv *.repo repo_bak [root@test yum.repos.d]$ls repo_bak
說明：本人採用的是客戶端服務端在同一臺設備上，爲了避免受其餘repo配置文件的干擾，咱們把之前的repo文件所有移動到另一個備份目錄裏，而後在/etc/yum.repo.d/ 下建立一個repo文件。
[my_base] name=this is test repo baseurl=file:///rpm/centos/$releasever/os/$basearch gpgcheck=0
說明：建立一個.repo的文件，將以上內容添加到該文件，解釋一下這個文件的內容，第一個中括號裏表示倉庫的名字，一般這個名字能夠順便起，通常不建議裏面帶空格，name=表示倉庫的簡要說明，baseurl= 表示倉庫的路徑，也就是repodata所在的目錄的父目錄，gpgcheck=0表示不檢查包的gpg驗證，若gpgcheck=1表示要驗證。添加以上內容咱們客戶端就能夠根據以上定義的baseurl去服務器倉庫裏找相應的包。
5.在客戶端清除yum緩存，查看倉庫列表
[root@test yum.repos.d]$yum clean all Loaded plugins: fastestmirror, security Cleaning repos: my_base Cleaning up Everything Cleaning up list of fastest mirrors [root@test yum.repos.d]$yum repolist Loaded plugins: fastestmirror, security Determining fastest mirrors my_base | 2.9 kB 00:00 ... my_base/primary_db | 6.0 kB 00:00 ... repo id repo name status my_base this is test repo 2 repolist: 2
說明：能夠看到咱們剛纔配置的倉庫信息，repo id 就是咱們剛纔在repo文件中寫的，也可看到裏面有2個包。看到以上信息就表示rpm倉庫在客戶端上的配置成功了。
6.裝包驗證
[root@test yum.repos.d]$yum install vsftpd Loaded plugins: fastestmirror, security Setting up Install Process Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package vsftpd.x86_64 0:2.2.2-24.el6 will be installed --> Finished Dependency Resolution Dependencies Resolved =================================================================================================================================== Package Arch Version Repository Size =================================================================================================================================== Installing: vsftpd x86_64 2.2.2-24.el6 my_base 156 k Transaction Summary =================================================================================================================================== Install 1 Package(s) Total download size: 156 k Installed size: 340 k Is this ok [y/N]: y Downloading Packages: Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Installing : vsftpd-2.2.2-24.el6.x86_64 1/1 Verifying : vsftpd-2.2.2-24.el6.x86_64 1/1 Installed: vsftpd.x86_64 0:2.2.2-24.el6 Complete!
說明：本人以兩個包做爲例子來演示搭建rpm的過程，可能裝這個包還有其餘依賴包，可是倉庫裏面沒有其餘依賴，可能會出現報錯的狀況。
以上就是本地搭建repo倉庫的過程。
下面我再說下如何搭建網絡rpm倉庫
1.先安裝httpd web服務器
[root@test yum.repos.d]$yum install httpd -y Loaded plugins: fastestmirror, security Setting up Install Process Determining fastest mirrors * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com base | 3.7 kB 00:00 base/primary_db | 4.7 MB 00:00 epel | 5.3 kB 00:00 epel/primary_db | 6.1 MB 00:00 extras | 3.4 kB 00:00 extras/primary_db | 29 kB 00:00 updates | 3.4 kB 00:00 updates/primary_db | 5.7 MB 00:00 Resolving Dependencies --> Running transaction check ---> Package httpd.x86_64 0:2.2.15-69.el6.centos will be installed --> Finished Dependency Resolution Dependencies Resolved =================================================================================================================================== Package Arch Version Repository Size =================================================================================================================================== Installing: httpd x86_64 2.2.15-69.el6.centos base 836 k Transaction Summary =================================================================================================================================== Install 1 Package(s) Total download size: 836 k Installed size: 3.0 M Downloading Packages: httpd-2.2.15-69.el6.centos.x86_64.rpm | 836 kB 00:00 Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Installing : httpd-2.2.15-69.el6.centos.x86_64 1/1 Verifying : httpd-2.2.15-69.el6.centos.x86_64 1/1 Installed: httpd.x86_64 0:2.2.15-69.el6.centos Complete!
說明：httpd默認工做路徑在/var/www/html/ 下，也就是放html網頁代碼的地方。
2.在httpd 的工做路徑下 建立目錄結構
[root@test ~]$mkdir -pv /var/www/html/centos/{6,7}/os/x86_64 mkdir: created directory `/var/www/html/centos' mkdir: created directory `/var/www/html/centos/6' mkdir: created directory `/var/www/html/centos/6/os' mkdir: created directory `/var/www/html/centos/6/os/x86_64' mkdir: created directory `/var/www/html/centos/7' mkdir: created directory `/var/www/html/centos/7/os' mkdir: created directory `/var/www/html/centos/7/os/x86_64'
3.掛載安裝光盤到相應的位置
[root@test ~]$mount /dev/sr0 /var/www/html/centos/6/os/x86_64/ mount: block device /dev/sr0 is write-protected, mounting read-only
說明：我這裏只掛載了centos6的一個安裝光盤，centos7下面的目錄也可使用一樣的方式掛載centos7的安裝光盤，這裏用centos6做爲演示。這裏還要說一下安裝光盤自己就有repodata目錄，咱們這裏就不須要再建立元數據信息。
4.開啓httpd
[root@test ~]$/etc/init.d/httpd start Starting httpd: httpd: apr_sockaddr_info_get() failed for test httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName [ OK ]
5.客戶端配置repo文件
[my_base] name=this is test repo baseurl=http://127.0.0.1/centos/$releasever/os/$basearch gpgcheck=0
說明：這裏只須要把倉庫的路徑改爲以http的協議方式去獲取，固然爲了避免受其餘yum源的影響，本次實驗咱們也要把其餘的repo文件放在一個備份目錄。
6.客戶端清除yum緩存，並查看倉庫列表
[root@test x86_64]$yum clean all Loaded plugins: fastestmirror, security Cleaning repos: my_base Cleaning up Everything [root@test x86_64]$yum repolist Loaded plugins: fastestmirror, security Determining fastest mirrors my_base | 4.0 kB 00:00 my_base/primary_db | 4.6 MB 00:00 repo id repo name status my_base this is test repo 6,575 repolist: 6,575
說明：能夠看到剛纔搭建的倉庫成功的出如今倉庫列表中了。
7.安裝一個包，驗證倉庫
[root@test ~]$yum install java -y Loaded plugins: fastestmirror, security Setting up Install Process Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check
