cloud
Network interface is static setup.
vi /etc/sysconfig/network-scripts/ifcfg-enp0s3
Delete your old text and insert from below and must be replace on your UUID, ip, netmask, gateway and dns.

Step #02 : Restart network, check internet is ok and selinux is disabled.
systemctl restart NetworkManager.service ping cloudstack.apache.org
Output as like below
PING cloudstack.apache.org (40.79.78.1) 56(84) bytes of data. 64 bytes from 40.79.78.1 (40.79.78.1): icmp_seq=1 ttl=43 time=272 ms 64 bytes from 40.79.78.1 (40.79.78.1): icmp_seq=2 ttl=43 time=276 ms 64 bytes from 40.79.78.1 (40.79.78.1): icmp_seq=3 ttl=43 time=275 ms 64 bytes from 40.79.78.1 (40.79.78.1): icmp_seq=4 ttl=43 time=273 ms 64 bytes from 40.79.78.1 (40.79.78.1): icmp_seq=5 ttl=43 time=272 ms 64 bytes from 40.79.78.1 (40.79.78.1): icmp_seq=6 ttl=43 time=274 ms
Config selinux status like permissive to disabled.
vi /etc/selinux/config
After server reboot and the connect again.

For connect server via ssh using Putty or Mobaxterm.
ssh -l root 10.66.100.70
Then press Enter and type your user password.
Step #03 : Install NTP and save Cloud Stack repo for version 4.15.
dnf -y install chrony wget
Create cloudstack repo file
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.
rpm -Uvh https://dev.mysql.com/get/Downloads/Connector-Python/mysql-connector-python-8.0.22-1.el7.x86_64.rpm --nodeps yum -y install mysql-server
After installation done then open server configuration file
vi /etc/my.cnf.d/mysql-server.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.
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. Mysql default root password is blank.
systemctl start mysqld mysql -u root -p
mysql 8 reset password command as like below
ALTER USER 'root'@'localhost' IDENTIFIED BY 'passw0rd'; \q
Now restart mysqld service then run cloud management installation command.
systemctl restart mysqld.service
yum -y install cloudstack-management
mysqld --skip-grant-tables --user=mysql
If see any error so please check properly installed Java 11.
alternatives --config java
Now run Cloud Stack setup database command.
cloudstack-setup-databases cloud:cloud@localhost --deploy-as=root:passw0rd
Output as like below
Mysql user name:cloud [ OK ] Mysql user password:****** [ OK ] Mysql server ip:localhost [ OK ] Mysql server port:3306 [ OK ] Mysql root user name:root [ OK ] Mysql root user password:****** [ OK ] Checking Cloud database files ... [ OK ] Checking local machine hostname ... [ OK ] Checking SELinux setup ... [ OK ] Detected local IP address as 10.66.100.70, will use as cluster management server node IP[ OK ] Preparing /etc/cloudstack/management/db.properties [ OK ] Applying /usr/share/cloudstack-management/setup/create-database.sql [ OK ] Applying /usr/share/cloudstack-management/setup/create-schema.sql [ OK ] Applying /usr/share/cloudstack-management/setup/create-database-premium.sql [ OK ] Applying /usr/share/cloudstack-management/setup/create-schema-premium.sql [ OK ] Applying /usr/share/cloudstack-management/setup/server-setup.sql [ OK ] Applying /usr/share/cloudstack-management/setup/templates.sql [ OK ] Processing encryption ... [ OK ] Finalizing setup ... [ OK ] CloudStack has successfully initialized database, you can check your database configuration in /etc/cloudstack/management/db.properties
Please ensure the following ports are open for the management server to function properly : 8080 8250 8443 9090.
Then check setup management using below command.
cloudstack-setup-management
output as like below
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.
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.
service iptables restart
systemctl enable iptables.service
You can check Cloud Stack log file using below command.
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.
vi /etc/idmapd.conf
Insert below line into idmapd.conf file then save and exit. Must be change my domain name and replace your domain name.
Domain = technologyrss.local
Then restart nfs and rpcbind services using below command.
service rpcbind restart service nfs-utils restart systemctl enable nfs-utils chkconfig rpcbind on rpcinfo -p
Step #06 : Mount secondary storage and downlaod systemvm template for ready storage server.
mkdir -p /mnt/secondary mount -t nfs 10.66.100.30:/mnt/share/ct_secondary /mnt/secondary /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).
umount /mnt/secondary 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://10.66.100.70:8080/client/#/user/login?redirect=%2F
http://10.66.100.70:8080/client/legacy/
Default login :
User name : admin Password : password
Then Go to Global configuration find and save this option.
set false to -> true
system.vm.use.local.storage
set true to -> false
ca.plugin.root.auth.strictness
set value = 10.66.11.9 (local server ip using apache web server for download iso, http://10.66.11.9/centos.iso)
secstorage.allowed.internal.sites
Remember it : Must be restart Cloud Stack Management server before access.
/bin/systemctl stop cloudstack-management.service
/bin/systemctl start cloudstack-management.service
Then check log file from below
tail -f /var/log/cloudstack/management/management-server.log
Setup time zone if not setting when install operating system.
timedatectl
Then link your local time zone
ls -l /etc/localtime
Now enable Asia/Dhaka time zone
timedatectl set-timezone Asia/Dhaka timedatectl
If needed any help so please go to YouTube channel for more details. Please submit your valuable comments and share to others.
Thanks to all.
