I am attempting to following instructions to install PostGIS here (to install the latest production release of PostGIS on CentOS 8.1):


---

In the section titled:

`Red Hat / Centos / Scientific Linux`

I do not understand exactly what it is I need to do there, or if I need to do it,or how to determine if I need to do anything in that section.

---

When I run this command on my CentOS 8 system, 

`$dnf list | grep postgis30_12`

I get:

```
postgis30_12.x86_64                                  3.0.1-2.rhel8                                     pgdg12
postgis30_12-client.x86_64                           3.0.1-2.rhel8                                     pgdg12
postgis30_12-devel.x86_64                            3.0.1-2.rhel8                                     pgdg12
postgis30_12-docs.x86_64                             3.0.1-2.rhel8                                     pgdg12
postgis30_12-gui.x86_64                              3.0.1-2.rhel8                                     pgdg12
postgis30_12-utils.x86_64                            3.0.1-2.rhel8                                     pgdg12
```

---

Question 1:
so therefore, is there anything in that section that I need to do?

Question 2:
After reading this section, how would I determine if I need to do anything?

Question 3:
And if so, what would that be?

---

When I run:

`create extension postgis;`

I get this error:


ERROR:  could not open extension control file "/usr/pgsql-12/share/extension/postgis.control": No such file or directory
When checking, indeed that file (postgis.control) is not there.

Question 4:
What am I missing?
---
sql>select version();`

PostgreSQL 12.2 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 8.3.1 20190507 (Red Hat 8.3.1-4), 64-bit

---
OS installed was: CentOS Linux release 8.1.1911 (Core)
(not sure why it says: Red Hat 8.3.1-4 in: select version();)

Devrim,

Thanks for the instructions, I added to this page -

I ran into a stumbling block on a fresh Centos 8.1

dnf -y config-manager --set-enabled PowerTools

Gave - "No such command: config-manager. Please use /usr/bin/dnf --help"

I had to do this beforehand -- can you add this line to the instructions
after the epel-release install.

yum install dnf-plugins-core

#It installed okay after, but when I go to do a yum update I get this error

yum update

(this 2nd one also applies to gdal as well :( )

More details:

So, this time EPEL and CentOS both got broken badly. You need to
install libzstd package manually in CentOS 8.1
