迁移glance镜像服务
一、迁移背景
当openstack管理的计算节点越来越多的时候，控制节点的压力越来越大，由于所有的服务都安装在控制节点，这时候控制节点上的openstack服务随时都团灭的风险。
openstack是基于soa架构设计的，已经实现了horizon的迁移，接下来，实现glance镜像服务的迁移，后面其他的服务都可以迁移，让控制节点只保留一个keystone服务，是soa架构的最佳实践。
本次，将glance镜像服务，由控制节点迁移到compute2上
二、glance镜像服务迁移的主要步骤
1：停止控制节点上的glance服务
2：备份迁移glance数据库
3：在新的节点上安装配置glance
4：迁移原有glance镜像文件
5：修改keystone中glance的api地址
6：修改所有节点nova配置文件中glance的api地址
7：测试，上传镜像，创建实例
三、实战迁移glance
1. 在控制节点上停止glance服务
[root@controller ~]# systemctl stop openstack-glance-api.service openstack-glance-registry.service [root@controller ~]# systemctl status openstack-glance-api.service openstack-glance-registry.service ● openstack-glance-api.service - OpenStack Image Service (code-named Glance) API server Loaded: loaded (/usr/lib/systemd/system/openstack-glance-api.service; enabled; vendor preset: disabled) Active: failed (Result: signal) since Sat 2020-11-21 23:01:54 CST; 1min 26s ago Main PID: 1136 (code=killed, signal=KILL) Nov 18 21:31:02 controller glance-api[1136]: /usr/lib/python2.7/site-packages/paste/deploy/loadwsgi.py:22: DeprecationWarning:...ately.

2. glance数据库迁移
1）备份数据库
[root@controller ~]# mysqldump -uroot -p123456 -B glance >/tmp/glance.sql [root@controller ~]# ll /tmp/glance.sql -rw-r--r-- 1 root root 23897 Nov 21 23:05 /tmp/glance.sql
[root@controller ~]# scp /tmp/glance.sql 10.0.0.13:/tmp/ The authenticity of host '10.0.0.13 (10.0.0.13)' can't be established. ECDSA key fingerprint is SHA256:GYtp4W43k6E/1PUlY9PGAT6HR+oI6j4E4HJF19ZuCHU. ECDSA key fingerprint is MD5:3f:b3:8b:8e:21:38:6f:51:ba:f4:67:ca:2a:bc:e1:34.

[root@computer2 opt]# mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on...
