1、前期准备
1.1 软硬件准备
控制主机三台（三网卡）+计算节点三台（双网卡、兼分布式存储OSD）+存储节点一台（双网卡部署MOD）
1.1.1组件
| 组件 | 版本 | 备注 |
|---|---|---|
| CentOS | CentOS Linux release 7.7.1908 (Core) | |
| Openstack | Rocky | |
| Ceph | ceph version 12.2.12 luminous (stable) |
1.1.2 网络拓扑（逻辑）
1.控制节点(cont01、cont02、cont03)运行MariaDB galeria,Haproxy,pacemaker,corosync,keystone, glance,horizon,nova&neutron&cinder管理相关组件和openstack相关的基础服务
2.计算节点(comp01、comp02、comp03)运行Nova-compute,neutron-openswitch-agent,ceph-osd等
3.存储控制节点(mon01)运行ceph-mon,ceph-mgr(如生产环境，建议也采用三个节点部署)
4.控制节点网络：
管理网络–>eth0:192.168.10.0/24 用于对openstack集群host os,api等网络管理
租户隧道VM网络–>eth1:10.10.10.0/24 用于集群内部的guest os之间的数据交换，采用vxlan/gre等方式
外部External网络–>eth2:主要用户计算节点访问internet/外部的floating ip
ps:此处的管理网络合并Management网络+API网络
5.计算节点网络：
管理网络–>eth0:192.168.10.0/24 用于对openstack集群host os,api等网络管理，
租户隧道网络–>eth1:10.10.10.0/24 用于集群内部的guest os之间的数据交换，采用vxlan/gre等方式
6.前端采用Haproxy做高可用，数据库采用MariaDB galeria，存储采用ceph分布式存储集群
7.无状态的服务，如xxx-api，采取active/active的模式运行；有状态的服务，如neturon-xxx-agent，cinder-volume等，建议采取active/passive的模式运行（因前端采用haproxy，客户端的多次请求可能会被转发到不同的控制节点，如果客户端请求被负载到无状态信息的控制节点，可能会导致操作请求失败）；自身具有集群机制的服务，如rabbitmq，memcached等采用本身的集群机制。
1.1.3 物理拓扑（部分参考）
1.2 配置hosts文件(集群所有电脑配置)
[root@cont02:/root]# vim /etc/hosts

1.5.1 所有节点关闭防火墙和selinux
systemctl stop firewalld && systemctl disable firewalld
setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=permissive/' /etc/selinux/config
1.5.2 所有节点编辑limits.conf和sysctl.conf文件

eofcat >>/etc/sysctl.conf<<eof fs.file-max=655350net.ipv4.ip_local_port_range = 1025 65000net.ipv4.tcp_tw_recycle = 1net.ipv4.ip_nonlocal_bind = 1
eofsysctl -p
2、部署MariaDB Galeria集群
2.1 控制节点安装mariadb(cont01、cont02、cont03)
Galera是Galera Cluster，是一种为数据库设计的新型的、数据不共享的、高度冗余的高可用方案，galera mariadb就是集成了Galera插件的MariaDB集群，Galera本身是具有多主特性的，所以galera mariadb不是传统的主备模式的集群，而是多主节点架构。
2.1.1 控制节点添加mariadb-10.4.11的yum源
[root@cont01:/root]# vim /etc/yum.repos.d/mariadb.repo
[mariadb]
name = MariaDB
baseurl = http://mirror.netinch.com/pub/mariadb//mariadb-10.4.11/yum/centos7-amd64/
gpgcheck = 0
enabled = 1
[root@cont01:/root]# yum makecache
[root@cont02:/root]#
cat > /etc/yum.repos.d/mariadb.repo << EOF
[mariadb]
name = MariaDB
baseurl = http://mirror.netinch.com/pub/mariadb//mariadb-10.4.11/yum/centos7-amd64/
gpgcheck = 0
enabled = 1
EOF
[root@cont02:/root]# yum makecache
[root@cont02:/root]# scp /etc/yum.repos.d/mariadb.repo cont03:/etc/yum.repos.d/
[root@cont03:/root]# yum makecache
2.1.2 控制节点yum安装mariadb软件包并开启服务
[root@cont01:/root]# yum -y install MariaDB-server MariaDB-client galera-4 rsync xinetd wget ntpdate
[root@cont01:/root]# systemctl enable mariadb && systemctl start mariadb
[root@cont01:/root]# systemctl status mariadb
[root@cont02:/root]# yum -y install MariaDB-server MariaDB-client galera-4 rsync xinetd wget ntpdate
[root@cont02:/root]# systemctl enable mariadb && systemctl start mariadb
[root@cont02:/root]# systemctl status mariadb
[root@cont03:/root]# yum -y install MariaDB-server MariaDB-client galera-4 rsync xinetd wget ntpdate
[root@cont03:/root]# systemctl enable mariadb && systemctl start mariadb
[root@cont03:/root]# systemctl status mariadb2.1.3 控制节点数据库安全设置、登陆数据库设置密码并授权

systemctl enable xinetd && systemctl start xinetd
systemctl status xinetd
3.5 故障场景的恢复
①首先判断当前数据库集群中是否有服务在启动着，如果有则直接启动服务即可，其中1个节点挂了，一般只需要重启A节点的服务即可。
② 如果当前所有节点的数据库服务都挂了，则需要找状态最新的那个节点让它携带–wsrep-new-cluster参数启动，启动起来之后其它节点直接启动服务即可。
查找最新节点策略：首先获取各节点的grastate.dat文件中的seqno值，值最大的那个就是最新的节点；如果所有节点的seqno都是-1，则去比较所有节点的gvwstate.dat文件中的my_uuid和view_id是否相等，相等的那个则作为第一个启动节点，第一个启动节点启动后，其它节点正常启动即可；如果依然未找到则需要人工干预来恢复了。//启动 mysqld_safe --defaults-file=/etc/my.cnf.d/server.cnf --user=mysql --wsrep-new-cluster &③如果以上两种方法全部无效。尝试采用下面操作(进过测试，此方法成功过)
第一步：数据库无法启动情况下把/var/lib/mysql下的几个文件：grastate.dat gvwstate.dat galera.cache mysql.sock统统删掉再重启
第二步：更改配置文件中的 “gcomm://” 是特殊的地址，仅仅是galera cluster初始化启动时候使用。如果集群启动以后，我们关闭了第一个节点，那么再次启动的时候必须先修改"gcomm://"为其他节点的集群地址，首次作为发起人则此处为空，不向任何人同步数据。
第三步：本机启动服务：systemctl start mariadb
第四部：启动集群：galera_new_cluster
第五步：启动其余节点上的mariadb: systemctl start mariadb
第六步：更改回 “gcomm://” 重启数据库systemctl restart mariadb
监测状态说明集群完整性检查:
wsrep_cluster_state_uuid:在集群所有节点的值应该是相同的,有不同值的节点,说明其没有连接入集群.
wsrep_cluster_conf_id:正常情况下所有节点上该值是一样的.如果值不同,说明该节点被临时”分区”了.当节点之间网络连接恢复的时候应该会恢复一样的值.
wsrep_cluster_size:如果这个值跟预期的节点数一致,则所有的集群节点已经连接.
wsrep_cluster_status:集群组成的状态.如果不为”Primary”,说明出现”分区”或是”split-brain”状况.节点状态检查:
wsrep_ready: 该值为ON,则说明可以接受SQL负载.如果为Off,则需要检查wsrep_connected.
wsrep_connected: 如果该值为Off,且wsrep_ready的值也为Off,则说明该节点没有连接到集群.(可能是wsrep_cluster_address或wsrep_cluster_name等配置错造成的.具体错误需要查看错误日志)
wsrep_local_state_comment:如果wsrep_connected为On,但wsrep_ready为OFF,则可以从该项查看原因.复制健康检查:
wsrep_flow_control_paused:表示复制停止了多长时间.即表明集群因为Slave延迟而慢的程度.值为0~1,越靠近0越好,值为1表示复制完全停止.可优化wsrep_slave_threads的值来改善.
wsrep_cert_deps_distance:有多少事务可以并行应用处理.wsrep_slave_threads设置的值不应该高出该值太多.
wsrep_flow_control_sent:表示该节点已经停止复制了多少次.
wsrep_local_recv_queue_avg:表示slave事务队列的平均长度.slave瓶颈的预兆.当前节点数据库状态

Primary :节点已处于集群中，在新节点加入时，选取donor进行数据库同步时会产生的状态
Joiner :节点处于等待接收或正在接收同步文件的状态
Joined :节点完成数据同步，但还有部分数据不是最新的，在追赶与集群数据一致的状态
Synced :节点正常提供服务的状态，表示当前节点数据状态与集群数据状态是一致的
Donor :表示该节点被选为Donor节点，正在为新加进来的节点进行全量数据同步，此时该节点对客户端不提供服务
4、部署rabbitmq消息队列
4.1、所有控制节点安装rabbitmq和erlang软件包（cont01、cont02、cont03、mon01）
//节点：cont01
[root@cont01:/root]# yum install epel-release -y
[root@cont01:/root]# yum install -y erlang rabbitmq-server.noarch
[root@cont01:/root]# systemctl enable rabbitmq-server && systemctl start rabbitmq-server
[root@cont01:/root]# systemctl status rabbitmq-server
[root@cont01:/root]# netstat -ntlpa | grep 5672
//节点：cont02
[root@cont02:/root]# yum install epel-release -y
[root@cont02:/root]# yum install -y erlang rabbitmq-server.noarch
[root@cont02:/root]# systemctl enable rabbitmq-server && systemctl start rabbitmq-server
[root@cont02:/root]# systemctl status rabbitmq-server
[root@cont02:/root]# netstat -ntlpa | grep 5672
//节点：cont03
[root@cont03:/root]# yum install epel-release -y
[root@cont03:/root]# yum install -y erlang rabbitmq-server.noarch
[root@cont03:/root]# systemctl enable rabbitmq-server && systemctl start rabbitmq-server
[root@cont03:/root]# systemctl status rabbitmq-server
[root@cont03:/root]# netstat -ntlpa | grep 5672
//节点：mon01
[root@mon01:/root]# yum install epel-release -y
[root@mon01:/root]# yum install -y erlang rabbitmq-server.noarch
[root@mon01:/root]# systemctl enable rabbitmq-server && systemctl start rabbitmq-server
[root@mon01:/root]# systemctl status rabbitmq-server
[root@mon01:/root]# netstat -ntlpa | grep 56724.2 查看集群状态

优化RabbitMQQ性能
在RabbitMQQ中，socket descriptors 和 File descriptors的默认配额并不大
修改配置
在其配置文件中添加如下参数，其值请根据实际情况进行调整：
vim /usr/lib/systemd/system/rabbitmq-erver.service
[Service]
LimitNOFILE = 16384
重启rabbitmq
systemctl daemon-reload
systemctl restart rabbitmq-server
//下面为引用参考文案，如下：(节后调整)
在为OpenStack的服务配置使用rabbitmq消息队列服务时，可以如下配置：
transport_url = rabbit://openstack:adminopenstack@cont01,openstack:adminopenstack@cont02,openstack:adminopenstack@cont03
可以看到这里的配置方式是将所有节点的rabbitmq服务以拼接方式拼在一起，当cont1节点上的消息队列服务不可用时可以将请求转发给cont2，再不行可以再转发给cont3节点.
同时应该配置如下参数：
rabbit_retry_interval=1
rabbit_retry_backoff=2
rabbit_max_retries=0
rabbit_durable_queues=true
rabbit_ha_queues=true
4.14 RabbitMQ注意小计（故障恢复提示）：
①保证集群中至少有一个磁盘类型的节点以防数据丢失，在更改节点类型时尤其要注意。
②若整个集群被停掉了，应保证最后一个down掉的节点被最先启动，若不能则要使用forget_cluster_node命令将其移出集群。
③若集群中节点几乎同时以不可控的方式down 了，此时再其中一个节点使用force_boot 命令重启节点。
④如果加入集群后，意外关闭等造成rabbitmq-server启动不成功，可以尝试一下步骤：/var/lib/rabbitmq/mnesia 目录下存在rabbit@localhost.pid、rabbit@localhost、rabbit@localhost-plugins-expand，删除这3项后，并且删除 /var/lib/rabbitmq/ 目录下 .erlang.cookie和erl_crash.dump 再使用systemctl start rabbitmq-server启动
5、部署PCS
5.1 安装pcs+pacemaker+corosync （cont01、cont02和 cont03）
所有控制节点安装pcs、pacemaker、corosync, pacemaker是资源管理器，corosync提供心跳机制。
[root@cont01:/root]# yum install -y lvm2 cifs-utils quota psmisc pcs pacemaker corosync fence-agents-all resource-agents crmsh
[root@cont02:/root]# yum install -y lvm2 cifs-utils quota psmisc pcs pacemaker corosync fence-agents-all resource-agents crmsh
[root@cont03:/root]# yum install -y lvm2 cifs-utils quota psmisc pcs pacemaker corosync fence-agents-all resource-agents crmsh
[root@cont01:/root]# systemctl enable pcsd corosync
[root@cont02:/root]# systemctl enable pcsd corosync
[root@cont03:/root]# systemctl enable pcsd corosync
[root@cont01:/root]# systemctl start pcsd && systemctl status pcsd
[root@cont02:/root]# systemctl start pcsd && systemctl status pcsd
[root@cont03:/root]# systemctl start pcsd && systemctl status pcsd
5.2 设置集群密码，而且三个节点密码需一直为：pcs#typora
[root@cont01:/root]# echo "pcs#typora" |passwd --stdin hacluster
[root@cont02:/root]# echo "pcs#typora" |passwd --stdin hacluster
[root@cont03:/root]# echo "pcs#typora" |passwd --stdin hacluster5.3 控制节点创建配置文件corosync.conf
[root@cont02:/root]# cat <<EOF>/etc/corosync/corosync.conf
totem { version: 2secauth:offcluster_name:openstack-clustertransport:udpu
}nodelist {node {ring0_addr:cont01 nodeid:1 }node {ring0_addr:cont02nodeid:2}node {ring0_addr:cont03nodeid:3}

}EOF[root@cont02:/root]# scp /etc/corosync/corosync.conf cont01:/etc/corosync/
[root@cont02:/root]# scp /etc/corosync/corosync.conf cont03:/etc/corosync/5.4 配置集群，设置集群互相认证
ssh-keygen
ssh-copy-id cont01
ssh-copy-id cont02
ssh-copy-id cont03
5.5 配置节点认证
[root@cont02:/root]# pcs cluster auth cont01 cont02 cont03 -u hacluster -p"pcs#typora"
cont02: Authorized
cont03: Authorized
cont01: Authorized
pcs cluster auth cont01 cont02 -u hacluster -p {password}
{password}表示为刚才设置的密码

[root@cont03:/root]# yum install python-openstackclient -y
[root@cont03:/root]# yum install openstack-selinux openstack-utils -y
注：安装openstack命令工具 openstack-utils，后期则可以使用openstack-config 命令配置openstack
7.2 控制节点安装 SQL database(cont01和cont02)
[root@cont01:/root]# yum install mariadb mariadb-server python2-PyMySQL -y
[root@cont01:/root]# vim /etc/my.cnf.d/server.cnf

[root@cont03:/root]# systemctl restart mariadb.service
[root@cont03:/root]# systemctl status mariadb.service//show status like 'wsrep_cluster_size';
7.3 安装Memcached (cont01、cont02和cont03)
[root@cont01:/root]# yum install memcached python-memcached -y
[root@cont01:/root]# vim /etc/sysconfig/memcached
PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="64"
OPTIONS="-l 127.0.0.1,::1,cont01"
[root@cont01:/root]# systemctl enable memcached.service && systemctl start memcached.service
[root@cont01:/root]# systemctl status memcached.service[root@cont02:/root]# yum install memcached python-memcached -y
[root@cont02:/root]# vim /etc/sysconfig/memcached
PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="64"
OPTIONS="-l 127.0.0.1,::1,cont02"
[root@cont02:/root]# systemctl enable memcached.service && systemctl start memcached.service
[root@cont02:/root]# systemctl status memcached.service[root@cont03:/root]# yum install memcached python-memcached -y
