This series of articles covers the entire process from OpenStack offline source creation to OpenStack installation. The OpenStack installation version used in this tutorial series is Version 20 Train (version T), and on May 13, 2020, the OpenStack community released version 21 Ussuri (Version U).

CSDN: OpenStack Ussuri Offline Installation and Deployment Series (full) OpenStack Train Offline Installation and Deployment Series (full) Looking forward to making progress together with you.

OpenStack Train offline deployment | 0 Create offline yum source

If offline source installation is used, it is usually necessary to configure the local PIP source;
If you install the offline software package, you usually need to configure the local YUM source.

Software installation

You are advised to change the yum source to a domestic source before installation

After the OpenStack installation package is downloaded to the local directory, you need to rebuild the YUM repository or update the original repository. Therefore, the repodata in the remote YUM repository may not be synchronized to the local after synchronization, and the repository path may have changed, so you only need to upgrade the local YUM repository. The command to create or update the local YUM repository is createrepo, which is provided by the Createrepo installation package.

Creating an YUM repository

# into each folder, CD/var/WWW/HTML/yumrepository CD. / base # yum using createrepo tool source, # yum install createrepo -y createrepo. # yum install createrepo -y createrepo. # yum install createrepo -y createrepo. [root@host-192-168-2-123 base]# ls Packages [root@host-192-168-2-123 base]# createrepo. Spawning worker 0 with 5049 pkgs Spawning worker 1 with 5048 pkgs Workers Finished Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete [root@host-192-168-2-123 base]# ls Packages repodata [root@host-192-168-2-123 base]#Copy the code

Note that this is required for each yum repository directory that is being synchronized.

After the RPM software library package is updated, go to the corresponding directory and use createrepo Update to synchronize. reposync -p /var/www/html/yumrepository/ createrepo --update .Copy the code

Configure the service HTTPD

systemctl start httpd
#Set automatic startup upon startup
systemctl enable httpd

On another machine, create a new repo file

# remove the original system built-in repo file, Ori_repo-config mv /etc/yum. Repos. D /*./ori_repo-config/ touch /etc/yum.repos.d/CentOS-PrivateLocal.repo vim /etc/yum.repos.d/CentOS-PrivateLocal.repoCopy the code

Note: ① Change the IP address to the yumRepository host address. 2. To avoid installation conflicts, only one [centos-openstack-stein] and [centos-openstack-train] are reserved.

After the configuration is complete, you need to clear the existing cache of yum and rebuild the cache. To clear the yum stale cache, run the following command:

yum clean all
yum makecache
