Installation

Here are my brief notes on getting CloudStack on Rocky Linux 8.4.

Refer to the installation guide at http://docs.cloudstack.apache.org/en/latest/quickinstallationguide/qig.html

Node setup

The following should be done prior to installing the management and/or agent components.

Disable SELinux

The system should have SELinux disabled.

# setenforce 0
# vi /etc/selinux/config 
## disable selinux

CloudStack Repos

Install CloudStack repos, then the CloudStack management package.

# cat > /etc/yum.repos.d/cloudstack.repo <<EOF
[cloudstack]
name=cloudstack
baseurl=http://download.cloudstack.org/centos/8/4.15/
enabled=1
gpgcheck=0
EOF

Install base packages

# yum -y install epel-release
# yum -y install bridge-utils net-tools

Management node setup

On the management node, setup the following components.

Network configuration

Setup networking 

# cat > /etc/sysconfig/network-scripts/ifcfg-cloudbr0 <<EOF
DEVICE=cloudbr0
TYPE=Bridge
ONBOOT=yes
BOOTPROTO=static
IPV6INIT=no
IPV6_AUTOCONF=no
DELAY=5
IPADDR=172.16.10.2
GATEWAY=172.16.10.1
NETMASK=255.255.255.0
DNS1=8.8.8.8
DNS2=8.8.4.4
STP=yes
USERCTL=no
NM_CONTROLLED=no
EOF

# systemctl stop firewalld
# systemctl disable firewalld

Install MySQL (cannot be MariaDB): 

# rpm -ivh http://repo.mysql.com/mysql80-community-release-el8.rpm
# yum -y install mysql-server
# yum -y install mysql-connector-python

## edit /etc/my.cnf to have the following lines.
cat >> /etc/my.cnf <<EOF
[mysqld]
innodb_rollback_on_timeout=1
innodb_lock_wait_timeout=600
max_connections=350
log-bin=mysql-bin
binlog-format = 'ROW'
EOF

# systemctl enable mysqld
# systemctl start mysqld

Setup storage 

# mkdir -p /export/primary /export/secondary
# yum -y install nfs-utils
# cat > /etc/exports <<EOF
/export/secondary *(rw,async,no_root_squash,no_subtree_check)
/export/primary *(rw,async,no_root_squash,no_subtree_check)
EOF
# systemctl start nfs-server
# systemctl enable nfs-server

Setup CloudStack. 

# yum -y install cloudstack-management

# cloudstack-setup-databases cloud:password@localhost --deploy-as=root
# cloudstack-setup-management
# systemctl start cloudstack-management
# systemctl enable cloudstack-management

# Seed the systemvm into secondary storage
# /usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt -m /export/secondary -u https://download.cloudstack.org/systemvm/4.15/systemvmtemplate-4.15.1-kvm.qcow2.bz2 -h kvm -F

At this point, you should have the CloudStack web UI available at http://cloudstack:8080/client. Login as admin / password. Continue the setup process via the web interface.

Agent node setup

The agent node must have virtualization enabled. /dev/kvm should exist. 

# yum -y install cloudstack-agent

## edit /etc/libvirt/qemu.conf 
vnc_listen=0.0.0.0

## edit /etc/libvirt/libvirtd.conf
listen_tls = 0
listen_tcp = 1
tcp_port = "16509"
auth_tcp = "none"
mdns_adv = 0

## edit /etc/sysconfig/libvirtd:
LIBVIRTD_ARGS="--listen"

# systemctl restart libvirtd
