这是搭建Openstack云平台的第二堂课，主要讲述公共组件中所需的数据库(MariaDB)、消息队列(RabbitMQ)、缓存(Memcached)和控制面板(Horizon)的配置方法。
部署数据库
安装MariaDB(或MySQL)：
|
1 |
yum -y install mariadb mariadb-server MySQL-python |
配置MariaDB
修改配置/etc/my.cnf：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
[mysqld] bind-address = 10.10.100.150 default-storage-engine = innodb innodb_file_per_table collation-server = utf8_general_ci character-set-server = utf8 #以下是性能优化方面的配置，请根据实际情况调整 #innodb_flush_method = O_DIRECT #innodb_file_per_table = 1 #wait_timeout = 28800 #binlog_cache_size = 16M #max_allowed_packet = 64M #expire_logs_days = 30 #sort_buffer_size = 128M #innodb_buffer_pool_size = 512M |
初始化MariaDB：
|
1 2 3 4 5 |
# 启动mariadb systemctl enable mariadb systemctl start mariadb # 初始化mariadb mysql_secure_installation |
依次设置密码(Mariadb123)及初始化数据库。
部署RabbitMQ
安装RabbitMQ
|
1 2 3 |
yum -y install rabbitmq-server systemctl enable rabbitmq-server systemctl start rabbitmq-server |
配置RabbitMQ用户
|
1 2 3 4 5 |
rabbitmqctl add_user openstack Openstack123 rabbitmqctl set_permissions openstack ".*" ".*" ".*" rabbitmqctl set_user_tags openstack administrator # 修改用户密码 # rabbitmqctl change_password <user_name> <new_password> |
部署Memcached
安装memcached
|
1 |
yum -y install memcached |
修改配置/etc/sysconfig/memcached：
|
1 |
OPTIONS="-l 10.10.100.150" |
启动memcached
|
1 2 |
systemctl enable memcached systemctl start memcached |
部署Dashboard
安装dashboard
|
1 |
yum -y install openstack-dashboard |
修改配置/etc/openstack-dashboard/local_settings：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 |
ALLOWED_HOSTS = ['*', ] OPENSTACK_API_VERSIONS = { "identity": 3, "image": 2, "volume": 2, } OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = 'Default' SESSION_ENGINE = 'django.contrib.sessions.backends.cache' CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 'LOCATION': 'controller:11211', }, } OPENSTACK_HOST = "controller" OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user" OPENSTACK_NEUTRON_NETWORK = { 'enable_router': False, 'enable_quotas': False, 'enable_distributed_router': False, 'enable_ha_router': False, 'enable_fip_topology_check': False, 'enable_lb': False, 'enable_firewall': False, 'enable_***': False, } TIME_ZONE = "Asia/Shanghai" |
注意：需要注释或删除原来的CACHES段中的内容！
