4.安装memcached OpenStack简介 OpenStack是由美国国家航空航天局NASA)与Rackspace公司合作研发并发起的以Apache许可证授权的自由软件和开放源代码的云计算技术解决方案其是一个项目也是一个软件主要用于实现云项目以云项目操作系统而存在。作用: 用于部署公有云、私有云并实现对云项目管理。 开发语言: Python 1.基础环境准备两个节点都需要部署
1.1关闭防火墙
systemctl stop firewalld systemctl disable firewalld
1.2关闭selinux
setenforce 0 sed -i s/SELINUXenforcing/SELINUXdisabled/g /etc/selinux/config
1.3修改主机名
#注意改成每个节点的名字
hostnamectl set-hostname 节点名字
1.4安装ntp时间服务器 【在控制节点】
yum install chrony vi /etc/chrony.conf systemctl enable chronyd.service systemctl start chronyd.service 【在其他节点】
yum install chrony
server controller iburst
systemctl enable chronyd.service systemctl start chronyd.service
1.5修改域名解析
vi /etc/hosts
172.16.21.37 controller
172.16.21.38 compute
172.16.21.39 cinder
1.6添加yum源
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum install -y centos-release-openstack-queens.noarch2.数据库安装配置
2.1安装数据库
yum install mariadb mariadb-server python2-PyMySQL -y
2.2修改数据库
[rootcontroller ~]# vim /etc/my.cnf.d/openstack.cnf
[mysqld]
bind-address 172.16.21.37
default-storage-engine innodb
innodb_file_per_table
max_connections 4096
collation-server utf8_general_ci
character-set-server utf82.3重启数据库
systemctl enable mariadb.service systemctl start mariadb.service
2.4初始化数据库
[rootcontroller ~]# mysql_secure_installationNOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDBSERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!In order to log into MariaDB to secure it, well need the current
password for the root user. If youve just installed MariaDB, and
you havent set the root password yet, the password will be blank,
so you should just press enter here.Enter current password for root (enter for none):
OK, successfully used password, moving on...Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..... Success!By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.Remove anonymous users? [Y/n] y... Success!Normally, root should only be allowed to connect from localhost. This
ensures that someone cannot guess at the root password from the network.Disallow root login remotely? [Y/n] n... skipping.By default, MariaDB comes with a database named test that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.Remove test database and access to it? [Y/n] y- Dropping test database...... Success!- Removing privileges on test database...... Success!Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.Reload privilege tables now? [Y/n] y... Success!Cleaning up...All done! If youve completed all of the above steps, your MariaDB
installation should now be secure.Thanks for using MariaDB!3.安装RabbitMq并配置
RabbitMq是一种应用程序对应用程序的通信方法。应用程序通过读写出入队列的消息针对应用程序的数据来通信而无需专用连接来链接它们。消息传递指的是程序之间通过在消息中发送数据进行通信而不是通过直接调用彼此来通信直接调用通常是用于诸如远程过程调用的技术。排队指的是应用程序通过队列来通信。队列的使用除去了接收和发送应用程序同时执行的要求。排队指的是应用程序通过 队列来通信。队列的使用除去了接收和发送应用程序同时执行的要求。
3.1安装RabbitMq
yum install -y rabbitmq-server
3.2启动并配置开机启动
systemctl enable rabbitmq-server.service systemctl start rabbitmq-server.service
3.3添加 openstack 用户
rabbitmqctl add_user openstack 000000
3.4给openstack用户开放权限
rabbitmqctl set_permissions openstack .* .* .*
查看一下
[rootcontroller ~]# rabbitmqctl list_users
Listing users
openstack []
guest [administrator]打开RabbitMq图像界面这一步可以不做
rabbitmq-plugins enable rabbitmq_management
4.安装memcached
memcached是一个开源的、高性能的分布式内存对象缓存系统。通过在内存中缓存数据和对象来减少读取数据库的次数从而提高网站访问速度减轻数据库负载。memcached是一种内存缓存把经常需要存储的对象或数据存在内存中。在内存中数据通过API的方式被存取数据经过利用HASH之后被存放到位于内存上的HASH表内HASH表中的数据已key-value的形式存放由于Memcached灭有实现访问认证及安全管理控制因此在面向Internet的系统架构中Memcached服务器通常位于用户的安全区域。
yum install memcached python-memcached -y
修改配置
[rootcontroller ~]# vi /etc/sysconfig/memcached
PORT11211
USERmemcached
MAXCONN1024
CACHESIZE64
OPTIONS-l 172.16.21.37,::1
systemctl enable memcached.service systemctl start memcached.service OpenStack简介 | 常见的基础组件
