How To Install Apache Cloud Stack v4.15 On Centos 7

I want to share open source cloud computing Apache Cloud Stack v4.15 installation process. This is latest release v4.15 including 250+ features with new UI. So lets start this installation process using centos 7.9 from my local server.

★ Private Cloud Setup Step By Step Using Apache Cloud Stack

★ How To Upgrade Zabbix Server 4.0 To 4.4 On CentOS 8

My server info :
IP address : 10.66.100.60
Operating System : Centos 7.9
RAM : 2 GB
Disk : 25 GB
vCPU : 2
CPU op-mode(s) : 64-bit
Service : Apache Cloud Stack v4.15
Database : Mysql 5.6
Java : 11 jdk

Step #01 : Check server version, hostname and ip address.

[root@cloud ~#] cat /etc/redhat-release

Output like below:

CentOS Linux release 7.9.2009 (Core)

See hostname setup correctly.

[root@cloud ~#] cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
10.66.100.60     cloud.technologyrss.local       cloud
[root@cloud ~#] cat /etc/hostname
cloud

Network interface is static setup.

[root@cloud ~#] cat /etc/sysconfig/network-scripts/ifcfg-enp0s3
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="none"
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="enp0s3"
UUID="2a40b8b9-8d93-467b-bf9a-d302b7c83e07"

IPADDR="10.66.100.60"
PREFIX="16"
GATEWAY="10.66.100.10"
DNS1="8.8.8.8"
IPV6_PRIVACY="no"

Step #02 : Restart network, check internet is ok and selinux is disabled.

[root@cloud ~#] service network restart
[root@cloud ~#] ping cloudstack.apache.org

[root@cloud ~#] cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

After server reboot and the connect again.

[root@cloud ~#] reboot

For connect server via ssh using Putty or Mobaxterm.

[root@cloud ~#] ssh -l 10.66.100.60

Then press Enter and type your user password.

Step #03 : Install NTP and save Cloud Stack repo for version 4.15.

[root@cloud ~#] yum -y install ntp chrony wget
[root@cloud ~#] vi /etc/yum.repos.d/cloudstack.repo

Insert below all lines into cloudstack.repo file then save and exit.

[cloudstack]
name=cloudstack
baseurl=http://cloudstack.apt-get.eu/centos/$releasever/4.15/
enabled=1
gpgcheck=0

Step #04 : Install mysql connector, mysql server and configure mysql server.

[root@cloud ~#] rpm -Uvh https://dev.mysql.com/get/Downloads/Connector-Python/mysql-connector-python-8.0.22-1.el7.x86_64.rpm --nodeps
[root@cloud ~#] wget http://repo.mysql.com/mysql-community-release-el7-7.noarch.rpm
[root@cloud ~#] rpm -ivh mysql-community-release-el7-7.noarch.rpm
[root@cloud ~#] yum -y install mysql-server
[root@cloud ~#] vi /etc/my.cnf

Insert below all lines into my.cnf file then save and exit.

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

Also create cloudstack.cnf file.

[root@cloud ~#] vi /etc/my.cnf.d/cloudstack.cnf

Insert below line into cloudstack.cnf file then save and exit.

[mysqld]

Start mysql service and reset mysql root password then install Cloud Stack management service.

[root@cloud ~#] systemctl start mysql
[root@cloud ~#] mysql -u root -p    // default password is blank.
Mysql > UPDATE mysql.user SET Password=PASSWORD('passw0rd') WHERE User='root';   // [for 5.6 mysql version]
Mysql > \q
[root@cloud ~#] systemctl restart mysql
[root@cloud ~#] yum -y install cloudstack-management

If see any error so please check properly installed Java 11.

[root@cloud ~#] alternatives --config java
  // press enter for keep it

Now run Cloud Stack setup database command.

[root@cloud ~#] cloudstack-setup-databases cloud:cloud@localhost --deploy-as=root:passw0rd

CloudStack has successfully initialized database, you can check your database configuration in /etc/cloudstack/management/db.properties

Then check setup management using below command.

[root@cloud ~#] cloudstack-setup-management

Starting to configure CloudStack Management Server:
Configure Firewall ...        [OK]
Configure CloudStack Management Server ...[OK]
CloudStack Management Server setup is Done!

Apache Cloud Stack installation done!!!

Step #05 : Configure iptables and nfs service for Cloud Stack version 4.15.

[root@cloud ~#] vi /etc/sysconfig/iptables

Insert below line into iptables file then save and exit.

-A INPUT -p tcp -m state --state NEW -m tcp --dport 8080 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 8250 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 8443 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 9090 -j ACCEPT

Insert below line into iptables file then save and exit. Then restart iptables service using below command.

[root@cloud ~#] service iptables restart

You can check Cloud Stack log file using below.

[root@cloud ~#] tail -f /var/log/cloudstack/management/management-server.log

Now wait at least 5 minutes for up and running web UI, then go to next steps.

NFS4 communication using network domain name, so must be add your network domain name into /etc/idmapd.conf file. Open this file via any editor.

[root@cloud ~#] vi /etc/idmapd.conf

Insert below line into idmapd.conf file then save and exit.

Domain = technologyrss.local   // Must be change my domain name and replace your domain name.

Then restart nfs and rpcbind services using below command.

[root@cloud ~#] service rpcbind start
[root@cloud ~#] service nfs start
[root@cloud ~#] chkconfig nfs on
[root@cloud ~#] systemctl enable nfs.service
[root@cloud ~#] chkconfig rpcbind on
[root@cloud ~#] rpcinfo -p

Step #06 : Mount secondary storage and downlaod systemvm template for ready storage server.

[root@cloud ~#] mkdir -p /mnt/secondary
[root@cloud ~#] mount -t nfs 10.66.100.30:/mnt/share/ct_secondary /mnt/secondary
[root@cloud ~#] /usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt -m /mnt/secondary -u http://download.cloudstack.org/systemvm/4.15/systemvmtemplate-4.15.0-kvm.qcow2.bz2 -h kvm -F

It will take to download at least 30 minutes. Then unmount secondary storage folder and remove created directory. (Note : This steps for seperate nfs server. If you use Cloud Stack Management server as nfs server so don’t remove this directory).

[root@cloud ~#] umount /mnt/secondary
[root@cloud ~#] rm -rf /mnt/secondary

Step #07 : This step for global configuration using local storage and allow internal site.

Access web UI using new UI or old UI.

http://10.66.100.60:8080/client/#/user/login?redirect=%2F
http://10.66.100.60:8080/client/legacy/

Then Go to Global configuration find and save this option.

system.vm.use.local.storage  [ set false to -> true
ca.plugin.root.auth.strictness  [ set true to -> false
secstorage.allowed.internal.sites [ set value = 10.66.11.9  (local server ip using apache web server for download iso, http://10.66.11.9/centos.iso)]

Remember it : Must be restart Cloud Stack Management server before access.

[root@cloud ~#] /bin/systemctl stop cloudstack-management.service
[root@cloud ~#] /bin/systemctl start cloudstack-management.service
[root@cloud ~#] tail -f /var/log/cloudstack/management/management-server.log

Setup time zone if not setting when install operating system.

[root@cloud ~#] timedatectl
[root@cloud ~#] ls -l /etc/localtime
[root@cloud ~#] timedatectl set-timezone Asia/Dhaka
[root@cloud ~#] timedatectl
