[Y/n] yNew password: 000000Re-enter new password: 000000Remove anonymous users? [Y/n] yDisallow root login remotely? [Y/n] nRemove test database and access to it? [Y/n] yReload privilege tables now? [Y/n] y测试数据库是否可正常登录很重要的步骤#mysql -uroot -p0000002.3 安装消息队列服务两节点安装客户端安装rabbitmq消息队列在controller节点执行#yum install rabbitmq-server -y#systemctl start rabbitmq-server.service#systemctl enable rabbitmq-server.service#systemctl status rabbitmq-server.service添加用户并赋予权限#rabbitmqctl add_user rabbitmq 000000#rabbitmqctl set_permissions rabbitmq .* .* .*修改rabbitmq参数#echo ulimit -n 65536
