This is a how-to install guide on setting up Apache CloudStack all in a single Ubuntu host that is also used as a KVM host.

Note: this should work for ACS 4.11.0 and above. This how-to post may get outdated in future, so please follow the latest docs and/or read the latest docs on KVM host installation.

Initial Setup

First install Ubuntu 16.04/18.04 LTS on your x86_64 system that has at least 4GB RAM (prerably more) with Intel VT-X or AMD-V enabled.

Install basic packages:

apt-get install openntpd openssh-server sudo vim htop tar

Allow the root user for ssh access using password, fix /etc/ssh/sshd_config. Change and remember the root password:

passwd root

Setup Networking

Setup Linux bridges that will handle CloudStack’s public, guest, management and storage traffic. For simplicity, all of these networks will use a single bridge cloudbr0. Install bridge utilities:

apt-get install bridge-utils

Ubuntu 16.04

To configure bridge on Ubuntu 16.04, make suitable changes to /etc/network/interfaces:

auto lo
iface lo inet loopback

auto enp2s0
iface enp2s0 inet manual

auto cloudbr0
iface cloudbr0 inet static
    address 192.168.1.10
    netmask 255.255.255.0
    gateway 192.168.1.1
    dns-nameservers 1.1.1.1
    bridge_ports enp2s0
    bridge_fd 0
    bridge_stp off

Restart networking or reboot the host to enforce network settings.

Ubuntu 18.04

This section is WIP.

Recent Ubuntu versions such as 18.04 use a new tool called netplan to manage network configuration. Use following netplan config to create bridge, /etc/netplan/01-netcfg.yaml:

 network:
   version: 2
   renderer: networkd
   ethernets:
     enp2s0:
       dhcp4: false
       dhcp6: false
       optional: true
   bridges:
     cloudbr0:
       addresses: [192.168.1.10/24]
       gateway4: 192.168.1.1
       nameservers:
         addresses: [1.1.1.1,8.8.8.8]
       interfaces: [enp2s0]
       dhcp4: false
       dhcp6: false
       parameters:
         stp: false
         forward-delay: 0

Setup Management Server

Install CloudStack management server and MySQL server: (run as root)

apt-key adv --keyserver keys.gnupg.net --recv-keys 584DF93F
echo deb http://packages.shapeblue.com/cloudstack/upstream/debian/4.11 / > /etc/apt/sources.list.d/cloudstack.list
apt-get update -y
apt-get install cloudstack-management mysql-server

Make a note of the MySQL server’s root user password. Configure InnoDB settings in mysql server’s /etc/mysql/mysql.conf.d/mysqld.cnf:

[mysqld]

server_id = 1
innodb_rollback_on_timeout=1
innodb_lock_wait_timeout=600
max_connections=350
log-bin=mysql-bin
binlog-format = 'ROW'

Restart MySQL server and setup database:

systemctl restart mysql
cloudstack-setup-databases cloud:cloud@localhost --deploy-as=root:<root-user-password> -i <cloudbr0 IP here>

Setup Storage

Setup NFS server and create exports:

mkdir -p /export/primary /export/secondary
apt-get install nfs-kernel-server quota
echo /export  *(rw,async,no_root_squash,no_subtree_check) > /etc/exports
exportfs -a
sed -i -e 's/^RPCMOUNTDOPTS="--manage-gids"$/RPCMOUNTDOPTS="-p 892 --manage-gids"/g' /etc/default/nfs-kernel-server
sed -i -e 's/^NEED_STATD=$/NEED_STATD=yes/g' /etc/default/nfs-common
sed -i -e 's/^STATDOPTS=$/STATDOPTS="--port 662 --outgoing-port 2020"/g' /etc/default/nfs-common
sed -i -e 's/^RPCRQUOTADOPTS=$/RPCRQUOTADOPTS="-p 875"/g' /etc/default/quota
service nfs-kernel-server restart

Seed systemvm template:

wget http://packages.shapeblue.com/systemvmtemplate/4.11/systemvmtemplate-4.11.0-kvm.qcow2.bz2
/usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt \
          -m /export/secondary -f systemvmtemplate-4.11.0-kvm.qcow2.bz2 -h kvm \
          -o localhost -r cloud -d cloud

Setup KVM host

Install KVM and CloudStack agent, configure libvirt:

apt-get install qemu-kvm cloudstack-agent
sed -i -e 's/listen_tls = 1/listen_tls = 0/g' /etc/libvirt/libvirtd.conf
echo 'listen_tcp=1' >> /etc/libvirt/libvirtd.conf
echo 'tcp_port = "16509"' >> /etc/libvirt/libvirtd.conf
echo 'mdns_adv = 0' >> /etc/libvirt/libvirtd.conf
echo 'auth_tcp = "none"' >> /etc/libvirt/libvirtd.conf
sed -i -e 's/\# vnc_listen.*$/vnc_listen = "0.0.0.0"/g' /etc/libvirt/qemu.conf
sed -i -e 's/libvirtd_opts.*/libvirtd_opts="-l"/' /etc/default/libvirt-bin
systemctl restart libvirtd

Configure Firewall

Configure firewall:

# configure iptables
NETWORK=192.168.1.0/24
iptables -A INPUT -s $NETWORK -m state --state NEW -p udp --dport 111 -j ACCEPT
iptables -A INPUT -s $NETWORK -m state --state NEW -p tcp --dport 111 -j ACCEPT
iptables -A INPUT -s $NETWORK -m state --state NEW -p tcp --dport 2049 -j ACCEPT
iptables -A INPUT -s $NETWORK -m state --state NEW -p tcp --dport 32803 -j ACCEPT
iptables -A INPUT -s $NETWORK -m state --state NEW -p udp --dport 32769 -j ACCEPT
iptables -A INPUT -s $NETWORK -m state --state NEW -p tcp --dport 892 -j ACCEPT
iptables -A INPUT -s $NETWORK -m state --state NEW -p tcp --dport 875 -j ACCEPT
iptables -A INPUT -s $NETWORK -m state --state NEW -p tcp --dport 662 -j ACCEPT

apt-get install iptables-persistent

Launch Management Server

Start your cloud:

cloudstack-setup-management
systemctl status cloudstack-management
tail -f /var/log/cloudstack/management/management-server.log

After management server is UP, proceed to http://cloudbr0-IP:8080/client and log in using the default credentials - username admin and password password.

Deploy Zone

Create a zone… WIP section

Keep an eye on your /var/log/cloudstack/management/management-server.log and /var/log/cloudstack/agent/agent.log for possible issues. Read the admin docs for more cloudy admin tasks. Have fun hacking your CloudStack cloud.
