openstack项目搭建

图中数字，如10，表示ip：192.168.99.10

---

全部服务器配置

控制端：
内存：5G
vcpu：4
计算节点：
内存：2G
vcpu：2

1. 准备yum源：/etc/yum.repos.d/openstack.repo

yum -y install centos-release-openstack-stein

2. 安装openstack客户端、openstack SELinux管理包

yum -y install python-openstackclient openstack-selinux

---

1、控制端: 101

1. 安装

yum -y install python2-PyMySQL mariadb

---

2、数据库106：配置SQL数据库

1. 安装组件

yum -y install  mariadb mariadb-server

2. 配置/etc/my.cnf.d/openstack.cnf

[mysqld]
bind-address = 192.168.99.116
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

3. 启动数据库和设置开机启动

systemctl enable mariadb.service
systemctl start mariadb.service

4. 经过运行脚原本保护数据库服务

mysql_secure_installation

---

3、数据库106：配置Memcached

1. 安装包：

yum -y install memcached python-memcached

2. 编辑/etc/sysconfig/memcached文件
   配置服务以使用控制器节点的管理IP地址。这是为了经过网络访问其余节点：

OPTIONS="-l 192.168.99.116"

3. 启动Memcached服务并将其配置为在系统引导时启动：

systemctl enable memcached.service
systemctl start memcached.service

---

4、ha_102:配置haproxy+keepalived

ha_1和ha_2都要配置

1. 安装keepalived和haproxy

yum -y install keepalived haproxy

2. 配置master_keepalived

vrrp_instance VI_1 {
    state MASTER
    interface eth0
    virtual_router_id 51
    priority 100
    advert_int 1
unicast_src_ip 192.168.99.112
unicast_peer {
        192.168.99.113
}
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        192.168.99.100 dev eth0 label eth0:1
    }
}

4. 启动

systemctl start keepalived
systemctl enable keepalived

5. haproxy配置

global
    log         127.0.0.1 local2

    chroot      /var/lib/haproxy
    pidfile     /var/run/haproxy.pid
    maxconn     4000
    user        haproxy
    group       haproxy
    daemon

    stats socket /var/lib/haproxy/stats

defaults
    mode                    http
    log                     global
    option                  httplog
    option                  dontlognull
    option http-server-close
    option forwardfor       except 127.0.0.0/8
    option                  redispatch
    retries                 3
    timeout http-request    10s
    timeout queue           1m
    timeout connect         10s
    timeout client          1m
    timeout server          1m
    timeout http-keep-alive 10s
    timeout check           10s
    maxconn                 3000

listen stats
        mode http
        bind :9999
        stats enable
        log global
        stats uri /haproxy-status
        stats auth admin:123
listen dashboard
        bind :80
        mode http
        balance source
        server dashboard 192.168.99.116:80 check inter 2000 fall 3 rise 5
listen mysql
        bind :3306
        mode tcp
        balance source
        server mysql 192.168.99.116:3306 check inter 2000 fall 3 rise 5
        
listen memcached
        bind :11211
        mode tcp
        balance source
        server memcached 192.168.99.116:11211 inter 2000 fall 3 rise 5
        
listen rabbit
        bind :5672
        mode tcp
        balance source
        server rabbit 192.168.99.116:5672 inter 2000 fall 3 rise 5
        
listen rabbit_web
        bind :15672
        mode http
        server rabbit_web 192.168.99.116:15672 inter 2000 fall 3 rise 5

启动

systemctl restart haproxy
systemctl enable haproxy

6. 配置内核参数

echo "net.ipv4.ip_nonlocal_bind=1" >> /etc/sysctl.conf
echo "net.ipv4.ip_forward=1" >> /etc/sysctl.conf
sysctl -p

---

5、数据库106：安装rabbit-MQ

567二、15672端口
7. 安装

yum -y install rabbitmq-server

8. 启动(端口5672)

systemctl enable rabbitmq-server
systemctl start rabbitmq-server

9. 添加用户和密码

rabbitmqctl add_user openstack 123

rabbitmqctl set_permissions openstack ".*" ".*" ".*"

11. 打开web插件（端口15672）

rabbitmq-plugins enable rabbitmq_management

12. 查看插件

rabbitmq-plugins list

13. 验证：有openstack这个用户

[mysql]$ rabbitmqctl list_users
Listing users
openstack       []
guest   [administrator]

14. web访问端口15672，用户密码都是guest
