### Openstack Mitaka HA 实施部署测试文档

#### 一、环境说明

##### 1、主机环境

```
controller(VIP) 192.168.10.100
controller01 192.168.10.101, 10.0.0.1
controller02 192.168.10.102, 10.0.0.2
controller03 192.168.10.103, 10.0.0.3
compute01 192.168.10.104, 10.0.0.4
compute02 192.168.10.105, 10.0.0.5
```
本次环境仅限于测试环境，主要测试HA功能。具体生产环境请对网络进行划分。

 

#### 二、配置基础环境


##### 1、配置主机解析


```
在对应节点上配置主机名：

hostnamectl set-hostname controller01
hostname contoller01

hostnamectl set-hostname controller02
hostname contoller02

hostnamectl set-hostname controller03
hostname contoller03

hostnamectl set-hostname compute01
hostname compute01

hostnamectl set-hostname compute02
hostname compute02
```


```
在controller01上配置主机解析：

[root@controller01 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.10.100 controller
192.168.10.101 controller01
192.168.10.102 controller02
192.168.10.103 controller03

192.168.10.104 compute01
192.168.10.105 compute02
```

##### 2、配置ssh互信


```
在controller01上进行配置：

ssh-keygen -t rsa -f ~/.ssh/id_rsa -P ''
ssh-copy-id -i .ssh/id_rsa.pub root@controller02
ssh-copy-id -i .ssh/id_rsa.pub root@controller03
ssh-copy-id -i .ssh/id_rsa.pub root@compute01
ssh-copy-id -i .ssh/id_rsa.pub root@compute02
```


```
拷贝主机名解析配置文件到其他节点
scp /etc/hosts controller02:/etc/hosts
scp /etc/hosts controller03:/etc/hosts
scp /etc/hosts compute01:/etc/hosts
scp /etc/hosts compute02:/etc/hosts
```

##### 3、yum 源配置

本次测试机所有节点都可以正常连接网络，故使用阿里云的openstack和base源


```
# 所有控制和计算节点开启yum缓存
[root@controller01 ~]# cat /etc/yum.conf 
[main]
cachedir=/var/cache/yum/$basearch/$releasever
# 开启缓存keepcache=1表示开启缓存，keepcache=0表示不开启缓存，默认为0
keepcache=1
debuglevel=2
logfile=/var/log/yum.log
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1
installonly_limit=5
bugtracker_url=http://bugs.centos.org/set_project.php?project_id=23&ref=http://bugs.centos.org/bug_report_page.php?category=yum
distroverpkg=centos-release

# 基础源
yum install wget -y
rm -rf /etc/yum.repos.d/*
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

# openstack mitaka源
yum install centos-release-openstack-mitaka -y
# 默认是centos源，建议修改成阿里云的，因为速度快
[root@contoller01 yum.repos.d]# vim CentOS-OpenStack-mitaka.repo 
# CentOS-OpenStack-mitaka.repo
#
# Please see http://wiki.centos.org/SpecialInterestGroup/Cloud for more
# information

[centos-openstack-mitaka]
name=CentOS-7 - OpenStack mitaka
baseurl=http://mirrors.aliyun.com//centos/7/cloud/$basearch/openstack-mitaka/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-Cloud


# galera源
vim mariadb.repo
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.1/centos7-amd64/
enable=1
gpgcheck=1
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
```

scp 到其他所有节点

```
scp CentOS-OpenStack-mitaka.repo controller02:/etc/yum.repos.d/CentOS-OpenStack-mitaka.repo
scp CentOS-OpenStack-mitaka.repo controller03:/etc/yum.repos.d/CentOS-OpenStack-mitaka.repo
scp CentOS-OpenStack-mitaka.repo compute01:/etc/yum.repos.d/CentOS-OpenStack-mitaka.repo
scp CentOS-OpenStack-mitaka.repo compute02:/etc/yum.repos.d/CentOS-OpenStack-mitaka.repo

scp mariadb.repo controller02:/etc/yum.repos.d/mariadb.repo
scp mariadb.repo controller03:/etc/yum.repos.d/mariadb.repo
scp mariadb.repo compute01:/etc/yum.repos.d/mariadb.repo
scp mariadb.repo compute02:/etc/yum.repos.d/mariadb.repo
```

 

##### 4、ntp配置
本机环境已经有ntp服务器，故直接使用。如果没有ntp服务器建议使用controller作为ntp服务器

```
yum install ntpdate -y
echo "*/5 * * * * /usr/sbin/ntpdate 192.168.2.161 >/dev/null 2>&1" >> /var/spool/cron/root
/usr/sbin/ntpdate 192.168.2.161
```

##### 5、关闭防火墙和selinux

```
systemctl disable firewalld.service
systemctl stop firewalld.service
sed -i -e "s#SELINUX=enforcing#SELINUX=disabled#g" /etc/selinux/config
sed -i -e "s#SELINUXTYPE=targeted#\#SELINUXTYPE=targeted#g" /etc/selinux/config
setenforce 0
systemctl stop NetworkManager
systemctl disable NetworkManager
```

##### 6、安装配置pacemaker


```
# 所有控制节点安装如下软件
yum install -y pcs pacemaker corosync fence-agents-all resource-agents
修改corosync配置文件
[root@contoller01 ~]# cat /etc/corosync/corosync.conf
totem {
version: 2
secauth: off
cluster_name: openstack-cluster
transport: udpu
}

nodelist {
node {
ring0_addr: controller01
nodeid: 1
}
node {
ring0_addr: controller02
nodeid: 2
}
node {
ring0_addr: controller03
nodeid: 3
}
}

quorum {
provider: corosync_votequorum
two_node: 1
}

logging {
to_syslog: yes
}
```

```
# 把配置文件拷贝到其他控制节点
scp /etc/corosync/corosync.conf controller02:/etc/corosync/corosync.conf
scp /etc/corosync/corosync.conf controller03:/etc/corosync/corosync.conf
```


```
# 查看成员信息
corosync-cmapctl runtime.totem.pg.mrp.srp.members
```

 

```


# 所有控制节点启动服务
systemctl enable pcsd
systemctl start pcsd

# 所有控制节点设置hacluster用户的密码
echo hacluster | passwd --stdin hacluster

# [controller01]设置到集群节点的认证
pcs cluster auth controller01 controller02 controller03 -u hacluster -p hacluster --force
# [controller01]创建并启动集群
pcs cluster setup --force --name openstack-cluster controller01 controller02 controller03
pcs cluster start --all
# [controller01]设置集群属性
pcs property set pe-warn-series-max=1000 pe-input-series-max=1000 pe-error-series-max=1000 cluster-recheck-interval=5min
# [controller01] 暂时禁用STONISH，否则资源无法启动
pcs property set stonith-enabled=false

# [controller01] 忽略投票
pcs property set no-quorum-policy=ignore

# [controller01]配置VIP资源，VIP可以在集群节点间浮动
pcs resource create vip ocf:heartbeat:IPaddr2 params ip=192.168.10.100 cidr_netmask="24" op monitor interval="30s"
```

##### 7、安装haproxy


```
# [所有控制节点] 安装软件
yum install -y haproxy

# [所有控制节点] 修改/etc/rsyslog.d/haproxy.conf文件
echo "\$ModLoad imudp" >> /etc/rsyslog.d/haproxy.conf;
echo "\$UDPServerRun 514" >> /etc/rsyslog.d/haproxy.conf;
echo "local3.* /var/log/haproxy.log" >> /etc/rsyslog.d/haproxy.conf;
echo "&~" >> /etc/rsyslog.d/haproxy.conf;

# [所有控制节点] 修改/etc/sysconfig/rsyslog文件
sed -i -e 's#SYSLOGD_OPTIONS=\"\"#SYSLOGD_OPTIONS=\"-c 2 -r -m 0\"#g' /etc/sysconfig/rsyslog

# [所有控制节点] 重启rsyslog服务
systemctl restart rsyslog

# 创建haproxy基础配置
vim /etc/haproxy/haproxy.cfg
#---------------------------------------------------------------------
# Example configuration for a possible web application. See the
# full configuration options online.
#
# http://haproxy.1wt.eu/download/1.4/doc/configuration.txt
#
#---------------------------------------------------------------------

#---------------------------------------------------------------------
# Global settings
#---------------------------------------------------------------------
global
# to have these messages end up in /var/log/haproxy.log you will
# need to:
#
# 1) configure syslog to accept network log events. This is done
# by adding the '-r' option to the SYSLOGD_OPTIONS in
# /etc/sysconfig/syslog
#
# 2) configure local2 events to go to the /var/log/haproxy.log
# file. A line like the following can be added to
# /etc/sysconfig/syslog
#
# local2.* /var/log/haproxy.log
#
log 127.0.0.1 local3
chroot /var/lib/haproxy
daemon
group haproxy
maxconn 4000
pidfile /var/run/haproxy.pid
user haproxy


#---------------------------------------------------------------------
# common defaults that all the 'listen' and 'backend' sections will
# use if not designated in their block
#---------------------------------------------------------------------
defaults
log global
maxconn 4000
option redispatch
retries 3
timeout http-request 10s
timeout queue 1m
timeout connect 10s
timeout client 1m
timeout server 1m
timeout check 10s

include conf.d/*.cfg
```

```
# 拷贝到其他控制节点
scp /etc/haproxy/haproxy.cfg controller02:/etc/haproxy/haproxy.cfg
scp /etc/haproxy/haproxy.cfg controller03:/etc/haproxy/haproxy.cfg
```

```
# [controller01]在pacemaker集群增加haproxy资源
pcs resource create haproxy systemd:haproxy --clone
# Optional表示只在同时停止和/或启动两个资源时才会产生影响。对第一个指定资源进行的任何更改都不会对第二个指定的资源产生影响，定义在前面的资源先确保运行。
pcs constraint order start vip then haproxy-clone kind=Optional
# vip的资源决定了haproxy-clone资源的位置约束
pcs constraint colocation add haproxy-clone with vip
ping -c 3 192.168.10.100
```


##### 8、galera安装配置


```
#所有控制节点上操作基本操作 ：安装、设置配置文件 
yum install -y MariaDB-server xinetd

# 在所有控制节点进行配置
vim /usr/lib/systemd/system/mariadb.service

```

##### 9、安装配置rabbitmq-server集群

```
# 所有控制节点
yum install -y rabbitmq-server


# 拷贝controller01上的cookie到其他控制节点上
scp /var/lib/rabbitmq/.erlang.cookie root@controller02:/var/lib/rabbitmq/.erlang.cookie
scp /var/lib/rabbitmq/.erlang.cookie root@controller03:/var/lib/rabbitmq/.erlang.cookie

# controller01以外的其他节点设置权限
chown rabbitmq:rabbitmq /var/lib/rabbitmq/.erlang.cookie
chmod 400 /var/lib/rabbitmq/.erlang.cookie


# 启动服务
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service

# 在任意控制节点上查看集群配置
rabbitmqctl cluster_status

# controller01以外的其他节点 加入集群
rabbitmqctl stop_app
rabbitmqctl join_cluster --ram rabbit@controller01
rabbitmqctl start_app


# 在任意节点 设置ha-mode
rabbitmqctl cluster_status;
rabbitmqctl set_policy ha-all '^(?!amq\.).*' '{"ha-mode": "all"}'

# 在任意节点执行创建用户
rabbitmqctl add_user openstack openstack
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
```

##### 10、安装配置memcache

```
yum install -y memcached

# controller01上修改配置
cat /etc/sysconfig/memcached 
PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="64"
OPTIONS="-l 192.168.10.101,::1"

# controller02上修改配置
cat /etc/sysconfig/memcached 
PORT="11211"

```

#### 三、安装配置openstack软件集群


```
# 所有控制节点和计算节点安装openstack 基础包
yum upgrade -y
yum install -y python-openstackclient openstack-selinux openstack-utils
```

##### 1、安装openstack Identity

```

# 在任意节点创建keystone数据库
mysql -uroot -popenstack -e "CREATE DATABASE keystone;
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY '"keystone"';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY '"keystone"';
FLUSH PRIVILEGES;"


# 所有节点安装keystone软件包
yum install -y openstack-keystone httpd mod_wsgi

# 任意节点生成临时token
openssl rand -hex 10
8464d030a1f7ac3f7207

# 修改keystone配置文件

openstack-config --set /etc/neutron/plugins/ml2/openvswitch_agent.ini securitygroup enable_security_group True
openstack-config --set /etc/neutron/plugins/ml2/openvswitch_agent.ini securitygroup enable_ipset True
openstack-config --set /etc/neutron/plugins/ml2/openvswitch_agent.ini securitygroup firewall_driver iptables_hybrid

openstack-config --set /etc/neutron/plugins/ml2/openvswitch_agent.ini ovs local_ip $(ip addr show dev ens192 scope global | grep "inet " | sed -e 's#.*inet ##g' -e 's#/.*##g')

openstack-config --set /etc/neutron/plugins/ml2/openvswitch_agent.ini agent tunnel_types vxlan
openstack-config --set /etc/neutron/plugins/ml2/openvswitch_agent.ini agent l2_population True

### 配置nova和neutron集成，/etc/nova/nova.conf
openstack-config --set /etc/nova/nova.conf neutron url http://controller:9696
openstack-config --set /etc/nova/nova.conf neutron auth_url http://controller:35357
openstack-config --set /etc/nova/nova.conf neutron auth_type password
openstack-config --set /etc/nova/nova.conf neutron project_domain_name default
openstack-config --set /etc/nova/nova.conf neutron user_domain_name default
openstack-config --set /etc/nova/nova.conf neutron region_name RegionOne
openstack-config --set /etc/nova/nova.conf neutron project_name service
openstack-config --set /etc/nova/nova.conf neutron username neutron
openstack-config --set /etc/nova/nova.conf neutron password neutron

ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini

systemctl restart openstack-nova-compute.service
systemctl start openvswitch.service
systemctl restart neutron-openvswitch-agent.service

systemctl enable openvswitch.service
systemctl enable neutron-openvswitch-agent.service
```

#### 五 修补
控制节点：

```
GRANT ALL PRIVILEGES ON *.* TO 'root'@'controller01' IDENTIFIED BY "openstack";
GRANT ALL PRIVILEGES ON *.* TO 'root'@'controller02' IDENTIFIED BY "openstack";
GRANT ALL PRIVILEGES ON *.* TO 'root'@'controller03' IDENTIFIED BY "openstack";
GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.10.101' IDENTIFIED BY "openstack";
GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.10.102' IDENTIFIED BY "openstack";
GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.10.103' IDENTIFIED BY "openstack";
```

rabbitmq集群相关：

```
/sbin/service rabbitmq-server stop
/sbin/service rabbitmq-server start
```

 

```
# 设置资源超时时间
pcs resource op defaults timeout=90s

# 清除错误
pcs resource cleanup openstack-keystone-clone
```

 


##### mariadb集群排错

```
报错描述如下：节点启动不了，查看 tailf /var/log/messages日志发现如下报错：
[ERROR] WSREP: gcs/src/gcs_group.cpp:group_post_state_exchange():321
解决错误: rm -f /var/lib/mysql/grastate.dat
然后重启服务即可
```


#### 六 增加dvr功能
##### 6.1 控制节点配置

```
vim /etc/neutron/neutron.conf
[DEFAULT]
router_distributed = true

vim /etc/neutron/plugins/ml2/ml2_conf.ini 
mechanism_drivers = openvswitch,linuxbridge,l2population

vim /etc/neutron/plugins/ml2/openvswitch_agent.ini
[DEFAULT]
enable_distributed_routing = true
[agent]
l2_population = True

vim /etc/neutron/l3_agent.ini 
[DEFAULT]
agent_mode = dvr_snat


vim /etc/openstack-dashboard/local_settings 
'enable_distributed_router': True,

重启控制节点neutron相关服务，重启httpd服务
```


##### 6.2 计算节点配置

```
vim /etc/neutron/plugins/ml2/ml2_conf.ini
[ml2]
mechanism_drivers = openvswitch,l2population


vim /etc/neutron/plugins/ml2/openvswitch_agent.ini
[DEFAULT]
enable_distributed_routing = true
[agent]
l2_population = True

vim /etc/neutron/l3_agent.ini 
[DEFAULT]
interface_driver = openvswitch
external_network_bridge =
agent_mode = dvr


重启neutron相关服务

ovs-vsctl add-br br-ex
ovs-vsctl add-port br-ex ens160
openstack-service restart neutron
```


关于rabbitmq连接数限制问题：


```
[root@controller01 ~]# cat /etc/security/limits.d/20-nproc.conf 
# Default limit for number of user's processes to prevent
# accidental fork bombs.
# See rhbz #432903 for reasoning.
* soft nproc 4096
root soft nproc unlimited
*    soft    nofile    10240
*    hard    nofile    10240

[root@controller01 ~]#ulimit -n 10240

[root@controller01 ~]#cat /usr/lib/systemd/system/rabbitmq-server.service
[Service]
LimitNOFILE=10240 #在启动脚本中添加此参数
[root@controller01 ~]#systemctl daemon-reload
[root@controller01 ~]#systemctl restart rabbitmq-server.service

[root@controller01 ~]#rabbitctl status
{file_descriptors,[{total_limit,10140},
{total_used,2135},
{sockets_limit,9124},
{sockets_used,2133}]}
```


#### 关于高可用路由器
只能在系统管理员页面上创建高可用或者DVR分布式路由器


# 关于image镜像共享
把控制节点中的/var/lib/glance/images 镜像目录共享出来。


yum -y install nfs-utils rpcbind -y
mkdir /opt/glance/images/ -p
vim /etc/exports
/opt/glance/images/ 10.128.246.0/23(rw,no_root_squash,no_all_squash,sync)

exportfs -r
systemctl enable rpcbind.service
systemctl start rpcbind.service
systemctl enable nfs-server.service 
systemctl start nfs-server.service


2、2个nova节点查看
showmount -e 10.128.247.153

# 三个控制节点挂载
mount -t nfs 10.128.247.153:/opt/glance/images/ /var/lib/glance/iamges/

chown -R glance.glance /opt/glance/images/


##########
普通用户创建HA路由器
```
neutron router-create router_demo --ha True
```
