這份紀錄如何預先下載套件，並建立 Local YUM Repo 讓其他 Container 存取。
這邊會使用到 HTTPD 服務，上一份已經預先處理好了。
這份筆記內容
- 延續上一篇筆記的環境，搭配 EDB 的軟體安裝檔作建立 YUM Repo 的示範。
- 使用 YUM Download Only 功能，預先準備需要的相依 RPM
這邊的範例，也可以適用到其他東西上～
(Note：這篇在 LXC 上面並不顯然喔，需要小小 Workaround 才行～)

取得這邊要示範的軟體安裝檔
EnterpriseDB 的產品，以 YUM Repo 的方式發布，需要由訂閱帳戶取得相關的登入帳密，方能下載。
設置 YUM Repo Container
這邊產生一個 Container，作為 Container 可以共同存取的 YUM Repository
[user@lxc-lab ~]$ sudo ./addcontainer.sh localrepo [user@lxc-lab ~]$ sudo ./startenv.sh localrepo [user@lxc-lab ~]$ ls addcontainer.sh envlogin.sh edb_11_redhat_rhel-7-x86_64.tar.gz startenv.sh edb_dependencies_redhat_rhel-7-x86_64.tar.gz stopenv.sh [user@lxc-lab ~]$ sudo ./startenv.sh Below is the List of Available containers NAME STATE IPV4 IPV6 AUTOSTART --------------------------------------------------- container1 RUNNING 192.168.68.11 - YES container2 RUNNING 192.168.68.12 - YES localrepo RUNNING 192.168.68.13 - YES [user@lxc-lab ~]$
放置相關檔案進去
[user@lxc-lab ~]$ sudo mv edb_11_redhat_rhel-7-x86_64.tar.gz edb_dependencies_redhat_rhel-7-x86_64.tar.gz /var/lib/lxc/localrepo/rootfs/root/ [user@lxc-lab ~]$
進入 Container 環境，開始進行 Repository 設置
[root@localrepo ~]# mkdir -p /var/www/html/edb11 /var/www/html/edb_dependencies [root@localrepo ~]# tar -xvf ~/edb_11_redhat_rhel-7-x86_64.tar.gz -C /var/www/html/edb11 [root@localrepo ~]# tar -xvf ~/edb_dependencies_redhat_rhel-7-x86_64.tar.gz -C /var/www/html/edb_dependencies [root@localrepo ~]# yum install -y createrepo [root@localrepo ~]# createrepo /var/www/html/edb11/ Spawning worker 0 with 39 pkgs Workers Finished Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete [root@localrepo ~]# createrepo /var/www/html/edb_dependencies Spawning worker 0 with 100 pkgs Workers Finished Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete [root@localrepo ~]#
設置 Apache HTTPD 服務，以便讓其他 Container 存取
HTTPD 服務要在 Container 產生之前，預先安裝到裡面。前面的筆記已經有作過調整，Container 初始化完成之後，就會裝好 HTTPD 軟體了。如果沒有預先裝的話，由於 CentOS 的 Container 的運作限制，yum install httpd 會下載失敗。
在本處的環境內，基本上直接啟動 HTTPD 服務就好，依照預設值，會在 80 Port 上啟動服務，並接受所有綁在這個 VM 的 IP 的請求。如果覺得有需要，可以調整 /etc/httpd/conf/httpd.conf 裡面的 Listen 選項，可以改 Port 或指定只理會特定 IP
[root@localrepo edb11]# sudo service httpd start Redirecting to /bin/systemctl start httpd.service [root@localrepo edb11]# chkconfig httpd on Note: Forwarding request to 'systemctl enable httpd.service'. Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service. [root@localrepo edb11]# [root@localrepo edb11]# netstat -tulnap | grep httpd tcp6 0 0 :::80 :::* LISTEN 300/httpd [root@localrepo edb11]#
此時可以離開 Container，到其他 Container 裡面設定 Repository。這邊簡便起見，可以直接在 Host 準備好 Repo FIle 再複製進去需要的 Container 就好。這邊用 container1 作示範就好
[user@lxc-lab ~]$ sudo tee ~/local-edb.repo << "EOF" [local-edb11] name=Local EPAS 11 Packages for Enterprise Linux 7 - $basearch baseurl=http://192.168.68.13:80/edb11/ enabled=1 gpgcheck=0 [local-edb-dependencies] name=Local EPAS Dependency Packages for Enterprise Linux 7 - $basearch baseurl=http://192.168.68.13:80/edb_dependencies/ enabled=1 gpgcheck=0 EOF [user@lxc-lab ~]$ sudo cp ~/local-edb.repo /var/lib/lxc/container1/rootfs/etc/yum.repos.d/ [user@lxc-lab ~]$
進入 container1 就可以查看 rpeolist 有生效了
[brandon_hsu@lxc-lab ~]$ sudo ./envlogin.sh container1

下載相依套件
本處示範的是 EDB 11 企業版。由於 EDB 11 需要額外的 LLVM 套件，需要額外先行下載，這邊使用 YUM Download 功能
[root@container1 ~]# yum install -y yum-plugin-downloadonly ...略 [root@container1 ~]# mkdir ~/edb11-db-alldep [root@container1 ~]# yum install -y epel-release ...略 [root@container1 ~]# yum install --downloadonly --downloaddir=edb11-db-alldep/ edb-as11-server -y ...略 [root@container1 ~]#
檢視下載結果：裡面的 llvm3.9 來自 EPEL，以及來自 localrepo 的 RPM
