部署mysql，memcache，RabbitMQ

每一個節點上安裝並配置yum源（需刪除epel源）

[root@linux-host1 ~]# mv /etc/yum.repo.d/* /tmp/
[root@linux-host1 ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@linux-host1 ~]# yum -y install centos-release-openstack-ocata
[root@linux-host1 ~]# yum install python-openstackclient openstack-selinux

配置mysql服務

安裝mariadb

[root@linux-host4 ~]# yum install -y mariadb-server

修改mariadb配置文件

[root@linux-host4 ~]# vim /etc/my.cnf
[client-server]

[mysqld]

socket=/var/lib/mysql/mysql.sock
symbolic-links=0
innodb_file_per_table=1
server_id=1
skip_name_resolve

[client]
port=3306
socket=/var/lib/mysql/mysql.sock

!includedir /etc/my.cnf.d

[root@linux-host4 ~]# vim /etc/my.cnf.d/openstack.cnf
[mysqld]
bind-address = 0.0.0.0 #監聽在本機的全部IP地址上
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

啓動服務

[root@linux-host4 ~]# systemctl start mariadb
[root@linux-host4 ~]# systemctl enable mariadb

安全加固

[root@linux-host4 ~]# mysql_secure_installation

配置memcache服務

安裝memcache

[root@linux-host4 ~]# yum -y install memcached

更改配置文件

[root@linux-host4 ~]# vim /etc/sysconfig/memcached
#監聽端口
PORT="11211"
USER="memcached"
#最大使用內存
MAXCONN="1024"
CACHESIZE="1024"
OPTIONS="-l 0.0.0.0,::1"

啓動服務

[root@linux-host4 ~]# systemctl start memcached.service
[root@linux-host4 ~]# systemctl enable memcached.service

配置RabbitMQ服務

配置主機名解析

[root@linux-host4 ~]# vim /etc/hosts
192.168.8.203 master

安裝RabbitMQ

[root@linux-host4 ~]# yum -y install rabbitmq-server

啓動服務

[root@linux-host4 ~]# systemctl enable rabbitmq-server.service
[root@linux-host4 ~]# systemctl start rabbitmq-server.service

添加 rabbitMQ 客戶端用戶並設置密碼

[root@linux-host4 ~]# rabbitmqctl add_user openstack 123

賦予 openstack 用戶讀寫權限

[root@linux-host4 ~]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"

打開 rabbitMQ 的 web 插件

[root@linux-host4 ~]# rabbitmq-plugins enable rabbitmq_management

查看插件

[root@linux-host4 ~]# rabbitmq-plugins list
