====How to install kernel-devel in Oracle Linux 7====
----

[+] Testing in my own environment.

Oracle 7 - 3.10.0-1160.80.1.0.1.el7.x86_64

* Agent installation with --install-boot-driver was successful. Replicated until CDP. `ce_disable_rmmod` was indeed Y.

Now testing on attempting to test on the same kernel as the customer's. (Used Oracle Linux 7.9 ISO).

1) wget https://yum.oracle.com/repo/OracleLinux/OL7/UEKR5/x86_64/getPackage/kernel-uek-4.14.35-2047.517.3.el7uek.x86_64.rpm

2) rpm -i kernel-uek-4.14.35-2047.517.3.el7uek.x86_64.rpm

3) reboot

4) Confirmed, it booted into the correct kernel:
uname -r
4.14.35-2047.517.3.el7uek.x86_64

5) Installed the ce agent using --install-boot-driver

sudo python ./installer_linux.py -t F8E3-5544-5E07-B3F2-A7A3-1A8D-DF3C-54B3-BDA9-6330-C8AA-2CC4-6E59-428E-294B-397C --install-boot-driver --compile --no-prompt

6) Keep failing to install. In my cloudendure.log, I see "kernel development package for '4.14.35-2047.517.3.el7uek.x86_64' are missing from repositories.

But in the customer's cloudendure.log, they don't have that either, but they were able to install the agent.

Tried running: `sudo yum install kernel-uek-devel-$(uname -r)`, no package available. I can only find the kernel-uek-devel package for another kernel (kernel-uek-devel-4.14.35-1818.1.x86_64.rpm ).

yumdownloader kernel-uek-devel-4.14.35-2047.517.3.el7uek.x86_64 # THIS WORKED!!
yum -y install libdtrace-ctf # This is a dependency to install kernel-uek-devel
rpm -i kernel-uek-devel-4.14.35-2047.517.3.el7uek.x86_64.rpm

->>>> This helped: https://sites.google.com/a/orabuntu-lxc.com/brandydandyoracle/oracle-linux-uek-kernel/getting-kernel-headers-for-oracle-linux-uek-kernels

[+] rpm -qi kernel-uek-4.14.35-2047.517.3.el7uek.x86_64.rpm

Build Date: Wed 07 Sep

Can also find the kernel-uek-devel rpm files from here: https://yum.oracle.com/repo/OracleLinux/OL7/UEKR5/archive/x86_64/index.html

====Setting Up Oracle 8 and DRS====
----
1) Spin up Oracle 8 linux.
* ISOs can be found here: https://yum.oracle.com/oracle-linux-isos.html
* Kernels can be found here: https://yum.oracle.com/repo/OracleLinux/OL8/UEKR6/x86_64/index.html

2) Set device configuration (Optional: with same LVM setup).

3) Set up steps:
- turned networking on (via gui if you installed with gui). Confirmed ping 8.8.8.8 works.
- edit /etc/resolv.conf with the following and confirmed ping google.com works:
nameserver 8.8.8.8

4) Update kernel to kernel-uek-5.4.17-2136.321 and install gcc:
# yum -y install gcc
# yum -y update
# sudo reboot

5) install DRS agent:

$ wget -O ./aws-replication-installer-init https://aws-elastic-disaster-recovery-us-east-1.s3.us-east-1.amazonaws.com/latest/linux/aws-replication-installer-init

$ chmod +x aws-replication-installer-init; sudo ./aws-replication-installer-init
