两小时openstack环境搭建(keystone)...未完待续……

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 update

apt install chrony

vim /etc/chrony/chrony.conf

service chrony restart

compute上

apt update

apt install chrony

vim /etc/chrony/chrony.conf

service chrony restart

chronyc sources

回到controller

chronyc sources

在两台虚拟机上

apt install software-properties-common

add-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-pymysql

vim /etc/mysql/mariadb.conf.d/99-openstack.cnf

[mysqld]

bind-address = 10.0.0.11

default-storage-engine = innodb

innodb_file_per_table = on

max_connections = 4096

collation-server = utf8_general_ci

character-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-memcache

vim /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 \

https://github.com/coreos/etcd/releases/download/${ETCD_VER}/etcd-${ETCD_VER}-linux-amd64.tar.gz \

-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 Restart=on-failure Type=notify ExecStart=/usr/bin/etcd --config-file /etc/etcd/etcd.conf.yml User=etcd
[Install] WantedBy=multi-user.target

systemctl enable etcd

systemctl start etcd

systemctl status etcd

安装并配置keyston服务

mysql

MariaDB [(none)]> CREATE DATABASE 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/keystone

provider = fernet

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

keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone

keystone-manage credential_setup --keystone-user keystone --keystone-group keystone

keystone-manage bootstrap --bootstrap-password ADMIN_PASS --bootstrap-admin-url http://controller:5000/v3/ --bootstrap-internal-url http://controller:5000/v3/ --bootstrap-public-url http://controller:5000/v3/ --bootstrap-region-id RegionOne

vim /etc/apache2/apache2.conf

ServerName controller

service apache2 restart

vim default-env

export OS_USERNAME=admin

export OS_PASSWORD=123456

export OS_PROJECT_NAME=admin

export OS_USER_DOMAIN_NAME=Default

export OS_PROJECT_DOMAIN_NAME=Default

export OS_AUTH_URL= http://controller:5000/v3

export OS_IDENTITY_API_VERSION=3

mv default-env /home/lxc/

chown lxc:lxc /home//lxc//default-env
