Use Cobbler And Ansible For Deploying CloudStack

CloudStack Management

Login to 10.15.33.5, we will start the deployment of the CloudStack Management Node.

More detailed documentation could be found at:
http://cloudstack-installation.readthedocs.org/en/latest/qig.html

Change Network Information

Without correct hostname, your deployment may meet some strange problems, so first we have to modify hostname via following steps:

# vim /etc/hostname 
CSMgmt
# vim /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
+ 127.0.0.1   CSMgmt
+ 10.15.33.5   CSMgmt

After reboot, verify hostname via:

# hostname --fqdn
CSMgmt

Installation Steps

1. Install and Configure NTP:

# yum install -y ntp
# vim /etc/ntp.conf
    driftfile /var/lib/ntp/drift

    restrict default kod nomodify notrap nopeer noquery
    restrict -6 default kod nomodify notrap nopeer noquery

    restrict 127.0.0.1 
    restrict -6 ::1

    server 0.uk.pool.ntp.org iburst
    server 1.uk.pool.ntp.org iburst
    server 2.uk.pool.ntp.org iburst
    server 3.uk.pool.ntp.org iburst

    includefile /etc/ntp/crypto/pw

    keys /etc/ntp/keys

    disable monitor
# service ntp restart
# chkconfig ntp on

2. SELinux Related configuration:

Install libselinux-python:

# yum install -y libselinux-python

Configure SELinux:

# vim /etc/selinux/config
SELINUX=permissive
SELINUXTYPE=targeted

After configurating SELinux, you'd better restart machine to let policy take effects.

3. MySQL

Install MySQL via:

# yum install -y mysql-server

Install MySQL python module:

# yum install -y MySQL-python

Configure MySQL's my.cnf file, add the following items before [mysqld_safe]:

# vim /etc/my.cnf
    + # CloudStack MySQL settings
    + innodb_rollback_on_timeout=1
    + innodb_lock_wait_timeout=600
    + max_connections=700
    + log-bin=mysql-bin
    + binlog-format = 'ROW'
    + bind-address=0.0.0.0

    [mysqld_safe]

Start and enable the mysqld server:

# service mysqld start
# chkconfig mysqld on

Remove anonymous user:

# mysql
mysql>  SELECT User, Host, Password FROM mysql.user;
+------+-----------+----------+
| User | Host      | Password |
+------+-----------+----------+
| root | localhost |          |
| root | csmgmt    |          |
| root | 127.0.0.1 |          |
|      | localhost |          |
|      | csmgmt    |          |
+------+-----------+----------+
mysql> DROP USER ''@'csmgmt'; 
mysql> DROP USER ''@'localhost'; 
mysql>  SELECT User, Host, Password FROM mysql.user;
+------+-----------+----------+
| User | Host      | Password |
+------+-----------+----------+
| root | localhost |          |
| root | csmgmt    |          |
| root | 127.0.0.1 |          |
+------+-----------+----------+
3 rows in set (0.00 sec)

Remove the testdb:

mysql> select * from mysql.db;
........
mysql> DELETE FROM mysql.db WHERE Db LIKE 'test%';
Query OK, 2 rows affected (0.00 sec)

mysql> select * from mysql.db;
Empty set (0.00 sec)
mysql> DROP DATABASE test;
Query OK, 0 rows affected (0.00 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
mysql> \q
Bye

Secure MySQL installation and change root user password, in fact all of the above configuration could be done here:

# mysql_secure_installation

Enable the iptables:

# iptables -A INPUT -p tcp -m tcp --dport 3306 -j ACCEPT
# vim /etc/sysconfig/iptables
+     -A INPUT -p tcp -m tcp --dport 3306 -j ACCEPT
    -A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
# service ntpd restart

4. Install CloudStack-Management

Install cloudstack management packages via:

# yum install -y cloudstack-management

5. Install Cloud-Monkey

Cloud-Monkey is for quickly configurating CloudStack, install it via:

# yum install -y python-pip
# pip install cloudmonkey

6. Configure CloudStack Database

# cloudstack-setup-databases cloud:engine@localhost \ 
--deploy-as=root:engine -i 10.15.33.5>>/root/cs_dbinstall.out 2>&1

7. Configure Management server

# cloudstack-setup-management >> /root/cs_mgmtinstall.out 2>&1

By now you could visit the Management node via:

# firefox http://10.15.33.5:8080/client/

Username/Password is admin/password.

You could check the version of the installed management node version:
