一、安装mysql
yum install -y mariadb mariadb-server python2-PyMySQL
配置my.cnf文件
vim /etc/my.cnf
[mysqld] bind-address = 192.168.10.53 default-storage-engine = innodb innodb_file_per_table = on max_connections = 4096 collation-server = utf8_general_ci character-set-server = utf8
启动mysql并加入开机自启动
systemctl enable mariadb.service
systemctl start mariadb.service
首次运行mysql先设置密码等（一路Y）
mysql_secure_installation
二、安装MQ
yum install -y rabbitmq-server
启动MQ
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service
添加openstack用户
rabbitmqctl add_user openstack 123456
设置openstack用户的权限
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
启用web管理
rabbitmq-plugins list #查看支持的插件 rabbitmq-plugins enable rabbitmq_management #启动插件 lsof -i:15672
在浏览器输入：http://IP:15672就可以访问MQ的web页面了，初始登陆用户为guest，密码一样。进去之后把openstack用户tags提权到administrator，将guest用户删除。
三、安装Memcached
yum install -y memcached python-memcached
配置memcached
vim /etc/sysconfig/memcached
OPTIONS="-l 192.168.10.53"
启动memcached
systemctl enable memcached.service
systemctl start memcached.service
