Cloudstack installation and management

Geicloudstack 1. Background

The private cloud environment of gei adopts the Apache open-source project cloudstack4.0.1 to be set up and used on centos6.3. Currently, three Dell machines are used as servers in the cloud environment. The login usernames and passwords of the three machines are root/geikrp.

Machines with IP address 192.168.7.33 are used as the Management Server of cloudstack, IP addresses 192.168.7.31 and 192.168.7.32 are used as computing resource nodes, and hypervisor is selected as KVM.

 

Ii. Installation (1) Steps for managing Server Installation

1. hostname-FQDN hostname -- FQDN: Check whether the host name meets the format requirements.

Eg: managament1.lab.example.org otherwise, perform the following operations:

Setting Method: Add IP hostname to the top line of VI/etc/hosts to save and exit.

2. Set SELinux

View the SELinux value. CAT/etc/SELinux/enforce will display 1

Setenforce 0 (this setting is invalid after the system restarts)

Set SELinux = permissive through VI/etc/SELinux/config -- à

3. Install the machine synchronization clock NTP service

Yum install NTP

VI/etc/NTP. conf -- à change server 127.0.0.1 # Remove local clock #

Service ntpd restart

4. configure the firewall (it is better to disable or enable the firewall temporarily)

Service iptables stop

Chkconfig iptables off (firewall permanently disabled)

5. Install NFS server

Yum install NTF-utils

Mkdir-P/export/secondary

VI/etc/exports

Add the following row

/Export * (RW, async, no_root_squash)

Exportfs-

Change NFS file configuration

VI/etc/sysconfig/nfs

Un-Comment thefollowing lines:

Mountd_nfs_v3 = "yes"

Lockd_tcpport = 32803

Lockd_udpport = 32769

Mountd_port = 892

Rquotad_port = 875

Statd_port = 662

Statd_outgoing_port = 2020

 

Set to start these services at startup

Chkconfig rpcbind on

Chkconfig NFS on

Service rpcbind start

Service NFS start

 

7. Upload the downloaded cloudstack4.0.1 (http://jenkins.cloudstack.org/view/4.0.1/ license file is cloudstack-non-oss-140.tar.bz2 to the management server host, decompress and install

Run./install. Sh in the directory.

Select cloudmanagementserver and Database Server

Select m first, and then perform the following steps:

You need to set boot to start some other services

Chkconfig rpcbind on

Chkconfig NFS on

Service rpcbind start

Service NFS start

 

Next, run./install. Sh.
Install MySQL
Select d

After installation, modify the my. CNF file.

VI/etc/My. CNF

Add [mysqld] onthe first line of the file

 

Innodb_rollback_on_timeout = 1

Innodb_lock_wait_timeout = 600

Max_connections = 350

Log-bin = mysql-bin

BINLOG-format = 'row'

 

Service mysqld restart

 

8. initialize the database

Cloud-setup-databasescloud: <dbpassword> @ localhost-deploy-as = root: <password> (example: cloud-setup-databases cloud: cloud @ localhost-deploy-as = root: password1)

9. Start the cloud-Management Service

Cloud-setup-Management

10. Prepare the system VM Template

First download, and then local upload better http://download.cloud.com/templates/acton/acton-systemvm-02062012.qcow2.bz2

Download the acton-systemvm-02062012.qcow2.bz2 File

Mkdircloudstackinpkg

Copy your acton-systemvm-02062012.qcow2.bz2} To cloudstackinpkg

Upload the template to Level 2 Storage

First as a mount Mount point

Mkdir/secondarymount

Mount-t nfs 192.168.7.33:/export/secondary/secondarymount

/Usr/lib64/cloud/common/scripts/storage/secondary/cloud-install-sys-tmplt-M/secondarymount-F/cloudstackinpkg/acton-systemvm-02062012.qcow2.bz2-h kvm-F

After the upload is successful, remember umount/secondarymount.

 

11. Restart service cloudstack Management

Service cloud-management restart

12 after the startup is successful, we can use cloudstack with the browser.

 

 

(2) Installation Steps on computing Resource Nodes

Steps 1-4 are the same as those on the management server.

5. After NFS is installed, you only need to create a shared directory of the primary storage.

Example: mkdir-P/export/primary

VI/etc/exports

Add the following row

/Export * (RW, async, no_root_squash)

Exportfs-

6. Install KVM

Rpm-Qa | grep KVM
If no information is displayed, you need to install KVM.

Yum install KVM

7. Install libvirt

Rpm-Qa | grep libvirt
If no information is displayed, you need to install libvirt.

Yum install libvirt

Configure libvirt VI/etc/libvirt/qemu. conf
Make sure vnc_listen = 0.0.0.0
Not commented out

VI/etc/libvirt/lib1_d. conf
Set the following information:

Listen_tls = 0

Listen_tcp = 1

Auth_tcp = 16059

Mdns_adv = 0

Service lib1_restart

8. Install cloudstack agent

Copy the cloudstack-non-oss-140.tar.bz2 downloaded from the Management Server to the machine, decompress the package, and run it in the directory.
./Install. Sh

Select
Install cloud-agent

Start cloud-agent service cloud-Agent start

 

So far, all installation is complete.

3. Admin manages cloudstack

Finally, use the Firefox browser, ie and Google
Chrome compatibility is not very good.

Enter http: // 192.168.7.33: 8080/client/in the address bar of the browser to enter the cloudstack interface (the user name and password are both admin and admin)

1. Global settings

Management ---- à management. Network. CIDR
Set to 192.168.7.0/24

Site --- à secstorage. Allowed. Internal. sites is set to 192.168.7.0/24

Restart service cloud-management restart

2. Infrastructure-a zone-a pods -- a host -- a primary storage -- a secondary storage ----- launch
Zone

3. In a mature environment, you only need to create a VM.

Click "instance"-"add instance"-"select IOS template"-"select the required IOS template as required-" select a service solution ", and then start to install the system.
