一、新建虚拟机4g内存2cpu，unbutu系统

安装并设置时间同步服务

apt updateapt install chrony

vim /etc/chrony/chrony.conf

service chrony restart

compute上apt updateapt install chronyvim /etc/chrony/chrony.conf service chrony restartchronyc sources回到controllerchronyc sources在两台虚拟机上apt install software-properties-commonadd-apt-repository cloud-archive:queens

apt update && apt dist-upgrade

apt install python-openstackclient

安装并配置mysql数据库（controller上）

apt install mariadb-server python-pymysqlvim /etc/mysql/mariadb.conf.d/99-openstack.cnf[mysqld]bind-address = 10.0.0.11

default-storage-engine = innodb

innodb_file_per_table = onmax_connections = 4096collation-server = utf8_general_cicharacter-set-server = utf8

service mysql restart

mysql_secure_installation 回车 更改一下root密码 一路回车即可

mysql

exit

apt install rabbitmq-server

创建openstack用户rabbitmqctl add_user openstack 123456

rabbitmqctl set_permissions openstack "." "." ".*"

apt install memcached python-memcachevim /etc/memcached.conf

service memcached restart

groupadd --system etcd

useradd --home-dir "/var/lib/etcd" \

--system \

--shell /bin/false \

-g etcd \

etcd

mkdir -p /etc/etcd

chown etcd:etcd /etc/etcd

mkdir -p /var/lib/etcd

chown etcd:etcd /var/lib/etcd

.

ETCD_VER=v3.2.7

rm -rf /tmp/etcd && mkdir -p /tmp/etcd

curl -L \

\

-o /tmp/etcd-${ETCD_VER}-linux-amd64.tar.gz

tar xzvf /tmp/etcd-${ETCD_VER}-linux-amd64.tar.gz \

-C /tmp/etcd --strip-components=1

cp /tmp/etcd/etcd /usr/bin/etcd

cp /tmp/etcd/etcdctl /usr/bin/etcdctl

vim /lib/systemd/system/etcd.service

[Unit]

After=network.target

Description=etcd - highly-available key value store

[Service]

LimitNOFILE=65536

ExecStart=/usr/bin/etcd --config-file /etc/etcd/etcd.conf.yml

User=etcd

[Install]

WantedBy=multi-user.target

systemctl enable etcd

systemctl start etcdsystemctl status etcd

安装并配置keyston服务

mysql

MariaDB [(none)]> CREATE DATABASE keystone;

MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone. TO 'keystone'@'localhost' \

IDENTIFIED BY 'KEYSTONE_DBPASS';

MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone. TO 'keystone'@'%' \

IDENTIFIED BY 'KEYSTONE_DBPASS';

apt install keystone apache2 libapache2-mod-wsgi

ufw disable

vim /etc/keystone/keystone.conf修改下面两项connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystoneprovider = fernet

su -s /bin/sh -c "keystone-manage db_sync" keystone

keystone-manage fernet_setup --keystone-user keystone --keystone-group keystonekeystone-manage credential_setup --keystone-user keystone --keystone-group keystone

keystone-manage bootstrap --bootstrap-password ADMIN_PASS --bootstrap-admin-url --bootstrap-internal-url --bootstrap-public-url --bootstrap-region-id RegionOne

vim /etc/apache2/apache2.conf

ServerName controller

service apache2 restart

vim default-env

export OS_USERNAME=admin
