- Programming language Python2.7 + HTML + JScripts
- Front-end Web framework：Bootstrap
- Backend Web framework：Django
- Backend Task Framework：Celery + Redis
- KVM VM 'lifecycle' management functions
- Resource utilization (eg: CPU, MEM, disk, network)
- Instance control (such as: life cycle management, snapshot technology, Web Console, etc.)
- Device resource control (such as: online adjustment of memory, CPU resources, hot add, delete hard disk)
- Storage pool management
- Increase or decrease volumes to support mainstream storage types
- Resource utilization
- Network Management
- SDN is supported, the underlying network uses OpenVSwitch/Linux Bridge, IP address allocation, network card traffic restrictions, and so on.
- User Management
- Support user rights, user groups, user virtual machine resource allocation, etc.
- Host Machine
- Resource utilization, instance control
- Programming language：Python2.7
- Operating System：CentOS 7
- Network planning: Management network interface=1, virtualized data network>=1 (if you only need one network card to use OpenVswitch, you need to manually configure the network to avoid losing the network)
- SDN Requirements：OpenVswitch Or Linux Bridge
- Management Server: Perform 1-10 steps
- Compute Node: Perform 2/3/4 steps and execute ssh-copy-id in Step 5 on the management server
- For a better experience, it is recommended to use Chrome or Firefox browser. If you want to get virtual machine ip, please install qemu-guest-agent in the virtual machine (centos 6 needs to install libvirt>=2.3.0 or more)
- The host list and user center - the data of my virtual machine is updated. Tasks need to be configured in the task schedule.
- Step 1: the platform first adds the host (compute node)
- Step 2: adding a data type storage pool and a mirror storage pool
- Mirrored Storage Pool: The compute node adds a dir type storage pool, puts the ISO image file in the storage pool, or can make the ISO image file an NFS share. When adding a storage pool, select the NFS mode. (Note: In order to add a virtual machine can be loaded into the system image)
- Data storage pool: According to the page to add, it is mainly used to store virtual machine hard disk.
- Step 3: computing nodes add network, select bridge and nat mode
- Step 4: allocate virtual machines for compute nodes
- Step 5: Configure Task Scheduling to Automatically Update the VM Resource Information of Compute Nodes
- Configure Platform
# yum install zlib zlib-devel readline-devel bzip2-devel openssl-devel gdbm-devel libdbi-devel ncurses-libs kernel-devel libxslt-devel libffi-devel python-devel libvirt libvirt-client libvirt-devel gcc git mysql-devel -y
# mkdir -p /opt/apps/ && cd /opt/apps/
# git clone https://github.com/welliamcao/VManagePlatform.git
# cd VManagePlatform
# pip install -r requirements.txt
- Install KVM
A. turn off firewall，selinux
# systemctl stop firewalld.service && systemctl disable firewalld.service
# setenforce 0 (Temporary disabling)
# systemctl stop NetworkManager
# systemctl disable NetworkManager
B. install the kvm virtual machine
# yum install python-virtinst qemu-kvm virt-viewer bridge-utils virt-top libguestfs-tools ca-certificates libxml2-python audit-libs-python device-mapper-libs
# Start the service
# systemctl start libvirtd
Note: download virtio-win-1.5.2-1.el6.noarch.rpm, if you do not install the window virtual machine or use the image with virtio driver can not be installed
# rpm -ivh virtio-win-1.5.2-1.el6.noarch.rpm
Node server does not have to perform
# yum -y install dnsmasq
# mkdir -p /var/run/dnsmasq/
- Install OpenVswitch (If you use the underlying network using Linux Bridge can not be installed)
Install openvswitch
# yum install gcc make python-devel openssl-devel kernel-devel graphviz kernel-debug-devel autoconf automake rpm-build redhat-rpm-config libtool
# wget http://openvswitch.org/releases/openvswitch-2.3.1.tar.gz
# tar xfz openvswitch-2.3.1.tar.gz
# mkdir -p ~/rpmbuild/SOURCES
# cp openvswitch-2.3.1.tar.gz rpmbuild/SOURCES
# sed 's/openvswitch-kmod, //g' openvswitch-2.3.1/rhel/openvswitch.spec > openvswitch-2.3.1/rhel/openvswitch_no_kmod.spec
# rpmbuild -bb --without check ~/openvswitch-2.3.1/rhel/openvswitch_no_kmod.spec
# yum localinstall /root/rpmbuild/RPMS/x86_64/openvswitch-2.3.1-1.x86_64.rpm
If there is a python dependency error
# vim openvswitch-2.3.1/rhel/openvswitch_no_kmod.spec
BuildRequires: openssl-devel
Then add,
AutoReq: no
# systemctl start openvswitch
- Configure Libvirt use tcp connection
# vim /etc/sysconfig/libvirtd
LIBVIRTD_CONFIG=/etc/libvirt/libvirtd.conf
LIBVIRTD_ARGS="--listen"
# vim /etc/libvirt/libvirtd.conf
listen_tls = 0
listen_tcp = 1
tcp_port = "16509"
listen_addr = "0.0.0.0"
auth_tcp = "none"
# systemctl restart libvirtd
- Configure SSH trust
# ssh-keygen -t rsa
# ssh-copy-id -i ~/.ssh/id_rsa.pub root@ipaddress
- Install the database (MySQL, Redis)
Install MySQL
# yum install mysql-server mysql-client
# systemctl start mysqld.service
# mysql -u root -p
mysql> create database vmanage;
mysql> grant all privileges on vmanage.* to 'username'@'%' identified by 'userpasswd';
mysql>quit
Install Redis
# wget http://download.redis.io/releases/redis-3.2.8.tar.gz
# tar -xzvf redis-3.2.8.tar.gz
# cd redis-3.2.8
# make
# make install
# vim redis.conf
daemonize yes
