Devstack Installation First Experience (Ubuntu)

Recently started to install Devstack, encountered some problems, recorded, the main failure is to download various sources of network problems, choose the right source is very important.

About Virtual Machine Network, the use of bridging, so host and virtual function interoperability, but also to ensure that virtual function access to the external network

About the hardware configuration, more than 4G of memory, or the Nova service starts, will report memory allocation failure error

Steps:

1, first install git

sudo apt-get install git

2. Get Devstack Source Code (Liberty version)

git clone https://git.openstack.org/openstack-dev/devstack-b Stable/liberty

3. Make some changes after getting finished

Update Ubuntu source for domestic source

Reload source, file path:/etc/apt/sources.list

Change content for domestic sources, foreign sources due to limited use often will fail to provide a source of Ali

Write the above content to sources.list and then perform the following command update (insurance practice to back up the original sources.list, the following command is to clear the installed and then update)

sudo rm-fr/var/lib/apt/lists/*
sudo apt-get clean && sudo apt-get update && sudo apt-get upgrade

Change the source path of a get-pip.sh

Change the variable path of the devstack/tools/install_pip.sh Pip_get_pip_url to https://coding.net/u/xiaoquqi/p/pip/git/raw/master/ contrib/get-pip.py

Add LOCALRC file under Devstack (new version named local.conf, detailed usage reference Official document) compare important files (change host_ip to own IP)

Dest=/opt/stack



# screen_logdir= $DEST/logs/screen


host_ip=200.21.101.203 # controller IP

multi_host= True

# logfile= $DEST/logs/stack.sh.log

service_token=0210

admin_password=0210

mysql_password= 0210

rabbit_password=0210

service_password=0210

#LDAP_PASSWORD =0210

lock_path=/tmp


# to Get a clean install everytime

reclone=no

# To enable neutron

enable_service n-net

disable_service Q-svc

disable_service q-agt

disable_service q-dhcp

disable_service q-l3 disable_service

Q-meta

# Enable the Ceilometer services

Disable_service Ceilometer-acompute, Ceilometer-acentral,ceilometer-collector,ceilometer-api


# Enable Heat

disable_service Heat h-api H-eng

Replace PIP source

OpenStack is a python project a lot depends on the PIP install of course to change the PIP source

Execute the following command to

mkdir ~/.pip
cat << EOF > ~/.pip/pip.conf
[global]
Index-url = http://mirrors.aliyun.com/pypi/ simple/
trusted-host = mirrors.aliyun.com
EOF

The installation user must be a non-root user with sudo privileges (new user named stack)

AddUser Stack

Add sudo permissions to a stack

Add the following line to the/etc/sudoers

4, all ready to install

CD Devstack &&./stack.sh

5, the installation is completed will come out information, and then login Danshborad can play
