openstack controller ha测试环境搭建记录（十五）——创建实例的相关文章

openstack controller ha测试环境搭建记录（一）——操作系统准备篇

为了初步了解openstack controller ha的工作原理,搭建测试环境进行学习. 在学习该方面知识时,当前采用的操作系统版本是centos 7.1 x64.首先在ESXi中建立2台用于测试的虚机,最小化安装完成centos,配置IP分别为10.0.0.12.10.0.0.13,主机名分别为controller2.controller3. 关闭防火墙:# systemctl stop firewalld# systemctl disable firewalld 修改主机名:# host

openstack controller ha测试环境搭建记录（二）——配置corosync和pacemaker

corosync.conf请备份再编辑:# vi /etc/corosync/corosync.conf totem {        version: 2 token: 10000        token_retransmits_before_loss_const: 10        secauth: off        rrp_mode: active interface {                ringnumber: 0                bindnetaddr

openstack controller ha测试环境搭建记录（十二）——配置neutron（计算节点）

在计算节点配置内核参数:vi /etc/sysctl.confnet.ipv4.conf.all.rp_filter=0net.ipv4.conf.default.rp_filter=0 在计算节点使内核参数立即生效:sysctl -p 在计算节点安装软件:yum install -y openstack-neutron-ml2 openstack-neutron-openvswitch 在计算节点修改配置文件:openstack-config --set /etc/neutron/neutro

openstack controller ha测试环境搭建记录（十四）——配置cinder（存储节点）

先简述cinder存储节点的配置:  1.IP地址是10.0.0.41:  2.主机名被设置为block1:  3.所有节点的hosts文件已添加相应条目:  4.已经配置了ntp时间同步:  5.已安装lvm2,并设置为开机自动启动:  6.已经挂载了新的存储设备/dev/sdb. 在存储节点执行下列命令:pvcreate /dev/sdb1vgcreate cinder-volumes /dev/sdb1 在存储节点和计算节点执行df命令:# df -hFilesystem         

openstack controller ha测试环境搭建记录（六）——配置keystone

在所有节点的hosts文件添加:10.0.0.10 myvip 在所有节点安装# yum install -y openstack-keystone python-keystoneclient# yum install -y openstack-utils 在所有节点设置keystone.conf文件使用mysql集群地址:# openstack-config --set /etc/keystone/keystone.conf database connection mysql://keysto

openstack controller ha测试环境搭建记录（十三）——配置cinder（控制节点）

在任一控制节点创建用户:mysql -u root -pCREATE DATABASE cinder;GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY '123456';GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY '123456'; 在任一控制节点创建相关用户:source admin-openrc.shkeystone u

openstack controller ha测试环境搭建记录（三）——配置haproxy

haproxy.cfg请备份再编辑:# /etc/haproxy/haproxy.cfg global    chroot /var/lib/haproxy    daemon    group haproxy    maxconn 4000    pidfile /var/run/haproxy.pid    user haproxy defaults    log global    maxconn 4000    option redispatch    retries 3    time

openstack controller ha测试环境搭建记录（四）——配置mysql数据库集群

内容正式开始前,我已经在集群中添加了新的节点controller1(IP地址为10.0.0.14). 安装软件:# yum install -y mariadb-galera-server xinetd rsync 创建用于健康检查的用户:# systemctl start mysqld.service# mysql -e "CREATE USER 'clustercheck'@'localhost' IDENTIFIED BY '123456';"# systemctl stop m

openstack controller ha测试环境搭建记录（十一）——配置neutron（网络节点）

在网络节点配置内核参数:vi /etc/sysctl.confnet.ipv4.ip_forward=1net.ipv4.conf.all.rp_filter=0net.ipv4.conf.default.rp_filter=0 在网络节点使内核参数立即生效:sysctl -p 在网络节点安装软件:yum install -y openstack-neutron openstack-neutron-ml2 openstack-neutron-openvswitch 在网络节点修改配置文件:ope
