1. Experimental environment
| Host | CPU | RAM | hard disk | Network card | operating system |
|---|---|---|---|---|---|
| ct | Dual-core dual-thread-CPU virtualization enabled | 8G | 300G+1024G (CEPH block storage) | VMnet1 (Local Area Network) 192.168.100.12 / NAT-192.168.139.12 | Centos 7.6 (1810)-Minimal installation |
| ct1 | Dual-core dual-thread-CPU virtualization enabled | 8G | 300G+1024G (CEPH block storage) | VMnet1 (Local Area Network) 192.168.100.13 / NAT-192.168.139.13 | Centos 7.6 (1810)-Minimal installation |

2. Environment configuration (all hosts need to be configured)
1. Modify and add NAT network card configuration
##外网卡配置##
BOOTPROTO=static #修改网卡配置参数，修改为静态IP
ONBOOT=yes #开启设备开机启动
IPADDR=192.168.139.12、13、14 #添加字段，静态模式IP自定义
NETMASK=255.255.255.0 #添加字段，设置网段
GATEWAY=192.168.184.2 #添加字段，设置网关
DNS1=192.168.184.2 #添加字段，设置DNS服务器
IPV4_ROUTE_METRIC=90 #设置网卡优先级，默认100，越低优先级越高，防止出现两张网卡为了抢占优先级导致无法连接问题
##内网卡配置##
BOOTPROTO=static
ONBOOT=yes
#末行添加#
IPADDR=192.168.100.12、13、14 #根据网段，设置VMnet1网段的IP，自定义
NETMASK=255.255.255.0 #设置掩码
systemcrl restart network #重启网卡
2. Turn off the firewall and system security mechanism
systemctl stop firewalld
setenforce 0
3. Install the basic environment dependency package
yum -y install net-tools bash-completion vim gcc gcc-c++ make pcre pcre-devel expat-devel cmake bzip2 lrzsz #多次安装确保最新版本
yum -y install centos-release-openstack-train python-openstackclient openstack-selinux openstack-utils #通用多次安装
4. Configure the host mapping file
echo '192.168.100.12 ct' >> /etc/hosts
echo '192.168.100.13 c1' >> /etc/hosts
echo '192.168.100.14 c2' >> /etc/hosts
5. Three nodes do free interaction
ssh-keygen -t rsa #一直回车即可
ssh-copy-id ct
ssh-copy-id c1
ssh-copy-id c2
6. Configure DNS, configure control node time synchronization
- All node operations
echo 'nameserver 114.114.114.114' >> /etc/resolv.conf
- ct node operation (192.168.139.12) time synchronization
yum install chrony -y
vim /etc/chrony.conf
##注释##
#server 0.centos.pool.ntp.org iburst
#server 1.centos.pool.ntp.org iburst
#server 2.centos.pool.ntp.org iburst
#server 3.centos.pool.ntp.org iburst
server ntp6.aliyun.com iburst #配置阿里云时钟服务器源
allow 192.168.100.0/24 #允许192.168.100.0/24网段的主机来同步时钟服务
systemctl enable chronyd
systemctl restart chronyd
chronyc sources #使用chronyc sources命令查询时间同步信息
- Compute node ct1, ct2 time synchronization
vim /etc/chrony.conf
##注释##
#server 0.centos.pool.ntp.org iburst
#server 1.centos.pool.ntp.org iburst
#server 2.centos.pool.ntp.org iburst
#server 3.centos.pool.ntp.org iburst
server ct iburst #配置阿里云时钟服务器源，同步指向控制节点ct
systemctl enable chronyd.service
systemctl restart chronyd.service
chronyc sources
- Set up a scheduled task, synchronize the time every two minutes (all node operations)
crontab -e #创建计划任务
*/2 * * * * /usr/bin/chronyc sources >>/var/log/chronyc.log
crontab -l #查看计划任务
Three. System environment configuration
1. Install and configure MariaDB (control node ct192.168.139.12)
yum -y install mariadb mariadb-server python2-PyMySQL
yum -y install libibverbs
2. Add MySQL sub-configuration file, add the following content
vim /etc/my.cnf.d/openstack.cnf
[mysqld]
bind-address = 192.168.100.12 #填写自己内网ip
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8
systemctl start mariadb #开启服务
systemctl enable mariadb #设置开机自启动
3. Execute MariaDB installation and configuration script
mysql_secure_installation
Enter current password for root (enter for none): #输入当前root密码，回车
OK, successfully used password, moving on...
Set root password? [Y/n] Y #是否需要更改root密码，Y确认
Remove anonymous users? [Y/n] Y #是否移除其他用户，Y确认移除
... Success!
Disallow root login remotely? [Y/n] n #是否不允许root用户远程登陆，输入n，允许root用户远程登陆
... skipping.
Remove test database and access to it? [Y/n] Y #是否删除test测试库，Y确认删除
Reload privilege tables now? [Y/n] Y #是否刷新规则，Y确认刷新
4. Install RabbitMQ
yum -y install rabbitmq-server #安装RabbitMQ服务
systemctl start rabbitmq-server.service #启动服务
systemctl enable rabbitmq-server.service #设置开机自启动
rabbitmqctl add_user openstack RABBIT_PASS #创建消息队列用户,用于controler和 计算节点连接rabbitmq的认证（关联）
rabbitmqctl set_permissions openstack ".*" ".*" ".*" #配置openstack用户的操作权限(正则，配置读写权限）
rabbitmq-plugins list #查看rabbitmq插件列表
rabbitmq-plugins enable rabbitmq_management #开启rabbitmq的web管理界面的插件，端口为15672
netstat -natp | grep 5672 #查看端口
主机访问192.168.139.12:15672 #默认账号密码为guest
5. Install memcached
yum install -y memcached python-memcachedz
6. Modify the memcached configuration file
vim /etc/sysconfig/memcached
PORT="11211" #memcached端口11211
USER="memcached" #用户memcached
MAXCONN="1024" #最大连接数1024
CACHESIZE="64" #字符集大小64位
OPTIONS="-l 127.0.0.1,::1,ct" #监听地址，127.0.0.1：本地地址，::是ipv6地址，ct是本地VMnet1地址
systemctl start memcached #开启服务
systemctl enable memcached #设置开机自启
netstat -nautp | grep 11211 #查看端口
7. Install etcd
yum -y install etcd
8. Modify the etcd configuration file
cd /etc/etcd/
vim etcd.conf
##删除所有内容，复制粘贴以下内容并进行修改##
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
ETCD_LISTEN_PEER_URLS="http://192.168.100.12:2380"
ETCD_LISTEN_CLIENT_URLS="http://192.168.100.12:2379"

ETCD_INITIAL_CLUSTER_STATE="new"
9. Set up auto-start, start service, detect port
systemctl start etcd.service
systemctl enable etcd.service
netstat -anutp |grep 2379
netstat -anutp |grep 2380
