### OpenStack 运维 - 部署Placement组件 ###

*  一、创建数据库实例和数据库用户
 *  二、创建 Placement 服务用户和 API 的 endpoint
 *   *  ① 创建placement用户
     *  ② 让placement用户对service项目拥有admin权限
     *  ③ 创建一个placement服务，服务类型为placement
     *  ④ 注册API端口到placement的service中
 *  三、安装 Placement 服务及修改配置文件
 *  四、导入数据库及修改 Apache 配置文件
 *  五、测试访问、检查端口及 Placement 的状态

# 一、创建数据库实例和数据库用户 #

mysql -u root -p
    create database placement;
    
    grant all privileges on placement.* to 'placement'@'localhost' identified by 'PLACEMENT_DBPASS';
    grant all privileges on placement.* to 'placement'@'%' identified by 'PLACEMENT_DBPASS';
    
    flush privileges;
    exit

# 二、创建 Placement 服务用户和 API 的 endpoint #

## ① 创建placement用户 ##

openstack user create --domain default --password PLACEMENT_PASS placement

## ② 让placement用户对service项目拥有admin权限 ##

openstack role add --project service --user placement admin

## ③ 创建一个placement服务，服务类型为placement ##

openstack service create --name placement --description "Placement API" placement

## ④ 注册API端口到placement的service中 ##

#注册的信息会写入到mysql中
    openstack endpoint create --region RegionOne placement public http://ct:8778
    openstack endpoint create --region RegionOne placement internal http://ct:8778
    openstack endpoint create --region RegionOne placement admin http://ct:8778

# 三、安装 Placement 服务及修改配置文件 #

yum -y install openstack-placement-api
    
    #备份配置文件
    cp -a /etc/placement/placement.conf{
        ,.bak}
    grep -Ev '^$|#' /etc/placement/placement.conf.bak > /etc/placement/placement.conf
    
    #传参
    openstack-config --set /etc/placement/placement.conf placement_database connection mysql+pymysql://placement:PLACEMENT_DBPASS@ct/placement
    openstack-config --set /etc/placement/placement.conf api auth_strategy keystone
    openstack-config --set /etc/placement/placement.conf keystone_authtoken auth_url  http://ct:5000/v3
    openstack-config --set /etc/placement/placement.conf keystone_authtoken memcached_servers ct:11211
    openstack-config --set /etc/placement/placement.conf keystone_authtoken auth_type password
    openstack-config --set /etc/placement/placement.conf keystone_authtoken project_domain_name Default
    openstack-config --set /etc/placement/placement.conf keystone_authtoken user_domain_name Default
    openstack-config --set /etc/placement/placement.conf keystone_authtoken project_name service
    openstack-config --set /etc/placement/placement.conf keystone_authtoken username placement
    openstack-config --set /etc/placement/placement.conf keystone_authtoken password PLACEMENT_PASS
    
    #检查参数
    cat /etc/placement/placement.conf

# 四、导入数据库及修改 Apache 配置文件 #

#导入数据
    su -s /bin/sh -c "placement-manage db sync" placement

![20210524144526967.png][]

vim /etc/httpd/conf.d/00-placement-api.conf
    
    #末尾添加以下配置
    <Directory /usr/bin>
    <IfVersion >= 2.4>
    	Require all granted
    </IfVersion>
    <IfVersion < 2.4>
    	Order allow,deny				
    	Allow from all
    </IfVersion>
    </Directory>
    
    #重启apache
    systemctl restart httpd

# 五、测试访问、检查端口及 Placement 的状态 #

curl ct:8778

netstat -natp | grep 8778
