基础环境准备，所需服务器及说明
172.16.2.51 base.test.com 基础服务节点
172.16.2.52 ctrl.test.com 控制节点
172.16.2.53 com1.test.com 计算节点
172.16.2.54 cin1.test.com 存储节点
一、 NTP Server
1、编辑配置文件：vim /etc/chrony.conf
allow 172.16.2.0/16 #允许同步时间的子网为172.16.2.0/16
local stratum 10 #本地时钟提供服务 2、启动服务：systemctl restart chronyd
systemctl enable chronyd
3、查看同步信息：chronyc sources -v
二、、 DNS Server
172.16.2.51 base.test.com
172.16.2.52 ctrl.test.com
172.16.2.53 com1.test.com
172.16.2.54 cin1.test.com
1、安装软件并修改配置文件
yum install bind -y
cp /etc/named.conf /etc/named.conf.bak
vim /etc/named.conf
options {listen-on port 53 { any; };directory "/var/named";dump-file "/var/named/data/cache_dump.db";allow-query { any; };
};
zone "test.com" IN {type master;
file "test.db";
}; 2、编辑解析文件test.db
cd /var/named ，备份cp named.empty test.db
vim test.db
$TTL 3H
@ IN SOA base.test.com. root.base.test.com. (0 ; serial1D ; refresh1H ; retry1W ; expire3H ) ; minimum
@ NS base.test.com.
base A 172.16.2.51
ctrl A 172.16.2.52
com1 A 172.16.2.53
cin1 A 172.16.2.54
chown named. test.db
3、开启DNS服务
systemctl restart named
systemctl enable named
systemctl status named
三、DB SQL
1、安装软件
yum install mariadb mariadb-server python2-PyMySQL -y
2、编辑配置文件
vim /etc/my.cnf.d/chen.cnf
[mysqld]
bind-address=172.16.2.51
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8 3、开启Mariadb服务
systemctl restart mariadb.service
systemctl enable mariadb.service
systemctl status mariadb.service
4、初始化数据库并查看用户信息
mysql_secure_installation
select user,host from mysql.user;
四、RabbitMQ
1、安装软件并启动服务
yum install rabbitmq-server
systemctl restart rabbitmq-server.service
systemctl enable rabbitmq-server.service
2、增加用户并设置权限
rabbitmqctl add_user openstack RABBIT_PASS
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
3、开启web管理
rabbitmq-plugins enable rabbitmq_management
登录：http://172.16.2.51:15672
用户：guest
密码：guest
五、 Memcached
1、安装软件
yum install memcached python-memcached -y
2、编辑配置文件
vim /etc/sysconfig/memcached
PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="64"
OPTIONS="-l 127.0.0.1,::1,base.test.com" 3、开启服务
systemctl restart memcached.service
systemctl enable memcached.service
systemctl status memcached.service
