Dear Haroon, As we cannot proceed using rpm without checksum value and yum repository, what if i download Interactive installer by EnterpriseDB from the link given on https://www.postgresql.org website, If there is any way we can get the checksum for the file provided by https://www.enterprisedb.com/downloads/postgres-postgresql-downloads location. As I did not find any. Regards, Saeed Ahmed From: Saeed Ahmed (DB) Dear Haroon, Really appreciate your prompt reply. There are some limitation due to company policy we are not having internet connection on the host to use the yum repository. The only option we have to manually copy the rpm to the host machine. So we cannot avail the Yum repository facility. If I download the file directly from the link mention below. Doest the checksum_data value will work for this particular RPM. checksum_data = d669c07f3c670299f2f1adc5a81ec90187bffc9aca0e8ceb7aa51a9194614910 Thanks.

We need a binary rpm for installation on linux RHEL7 environment and for that CHECKSUM is required. As the source tar file does not fulfill our requirement due to no expertise in compiling the source code. Is there any way as no success in finding the MD5 value for rpm on the website. Package installation via Yum should automatically take care of verifying checksum and GPG signature (unless you manually disable PGP verification). Yum repository where packages are hosted stores checksum and other relevant information in what is called yum db. So for example, for RHEL/CentOS 7.2, here's the Yum repository that contains relevant information on all the packages. (Please refer to the relevant files for your minor version of RHEL/CentOS) For information on specific packages in the repository, take a look here https://yum.postgresql.org/10/redhat/rhel-7.2-x86_64/repodata/3f8cd771d98c480622459107b80e97df46ffd9133dcba7976eab38bd6e36fbf4-primary.xml.gz. So for example, if you wanted to get checksum for postgresql10-server rpm package, here's this excerpt from the file linked above for postgresql10-server version 10.1 rpm package: <package type="rpm"> The highlighted entry above should give you the sha256 checksum of the package in question. Once you have installed the same package via Yum, you can verify this checksum against the installed package by running a query against yumdb. Essentially: yumdb info <package name> lists out the required information. For example, for postrgesql10-server package, here's the output: [haroon@localhost ~]$ yumdb info postgresql10-server Loaded plugins: fastestmirror, langpacks postgresql10-server-10.1-1PGDG.rhel7.x86_64 checksum_data = d669c07f3c670299f2f1adc5a81ec90187bffc9aca0e8ceb7aa51a9194614910 checksum_type = sha256 command_line = install postgresql10-server from_repo = pgdg10 from_repo_revision = 1516304771 from_repo_timestamp = 1516304876 installed_by = 1000 origin_url = https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-7-x86_64/postgresql10-server-10.1-1PGDG.rhel7.x86_64.rpm reason = user releasever = 7 var_infra = stock var_uuid = 3b612142-4be3-4551-b529-66391cfe3a9d Regards, Haroon This e-mail has been scanned for viruses by Forefront Protection @ Telenor Pakistan. |
