docker环境升级数据库

1、先部署数据库

bash 复制代码

1.#导入镜像
[root@node1 ~]# docker load -i kdb_x86_64_V009R001C002B0014.tar


2.#改标签
[root@node1 ~]# docker tag kingbase_v009r001c002b0014_single_x86:v1 kingbase:v1
[root@node1 ~]# docker images


3.#修改默认路径
#找到 Docker 实际的数据目录
[root@node1 ~]# docker info | grep -i "docker root dir"
 Docker Root Dir: /apps/docker
 
# 编辑/创建daemon.json文件
vim /etc/docker/daemon.json
{
        "data-root" : "/var/lib/docker",
        "insecure-registries" : ["10.3.90.106:8081"]
}

#迁移原有 Docker 数据到新目录	
mkdir /var/lib/docker
mv /apps/docker/* /var/lib/docker/

# 设置正确的权限（必须是root:root）
chown -R root:root /var/lib/docker
chmod -R 700 /var/lib/docker

# 重启Docker服务
systemctl daemon-reload
systemctl restart docker

2、运行实例

bash 复制代码

#完整启动命令示例
docker run -tid --privileged \
-p 4321:54321 \
-v /mnt/data:/home/kingbase/userdata/ \
-e NEED_START=yes \
-e DB_USER=kingbase \
-e DB_PASSWORD=123456 \
-e DB_MODE=mysql \
--name kingbase \
kingbase:v1 /usr/sbin/init

[root@node1 ~]# docker logs kingbase
[root@node1 ~]# ps -ef |grep data
kingbase   5095   4998  1 23:24 ?        00:00:00 /home/kingbase/install/kingbase/bin/kingbase -D /home/kingbase/userdata/data

3、升级前

bash 复制代码

[root@node1 ~]# docker exec -it kingbase /bin/bash

4、升级中

bash 复制代码

1.#停机备份
[root@node1 ~]# docker exec -it kingbase /bin/bash
[kingbase@900578af4dec ~]$ sys_ctl -D /home/kingbase/userdata/data/ stop
[kingbase@900578af4dec ~]$ exit
[root@node1 ~]# mkdir /mnt/data_bak
[root@node1 ~]# cp -r /mnt/data/ /mnt/data_bak/
#备份容器内程序目录到宿主机
#格式：docker cp 容器名:容器内路径 宿主机目标路径
[root@node1 ~]# docker cp kingbase:/home/kingbase/install/ /mnt/data_bak/


2.#升级（容器内直接访问升级包（无需拷贝））
#进入容器查看共享目录里的升级包
[root@node1 ~]# cp /kdb_install/kingbase-server-V009R001C002B0014PS055-linux-x86_64.tar /mnt/data
[root@node1 ~]# docker exec -it kingbase /bin/bash
[kingbase@900578af4dec ~]$ ls -l /home/kingbase/userdata/

# 能看到升级包，直接解压/使用即可
[root@node1 ~]# cp /kdb_install/kingbase-server-V009R001C002B0014PS055-linux-x86_64.tar /mnt/data

[kingbase@900578af4dec ~]$ tar xf /home/kingbase/userdata/kingbase-server-V009R001C002B0014PS055-linux-x86_64.tar -C /home/kingbase/install/kingbase/

[kingbase@900578af4dec ~]$ sys_ctl -D /home/kingbase/userdata/data/ start

5、升级后

bash 复制代码

[kingbase@900578af4dec ~]$ ksql
Type "help" for help.

kingbase=# select version();
                                                          version
---------------------------------------------------------------------------------------------------------------------------

(1 row)

kingbase=# select build_version;
 build_version

kingbase=# show database_mode;

(1 row)

与升级无关，就是测试删除是否可以恢复（容器被删）

创建测试数据

bash 复制代码

[root@node1 ~]# docker exec -it kingbase /bin/bash
[kingbase@900578af4dec ~]$ ksql

create table t1(id int);
insert into t1 values (1),(2),(3);
select * from t1;
 id
----
  1
  2
  3
(3 rows)

[kingbase@900578af4dec ~]$ sys_ctl -D /home/kingbase/userdata/data/ stop
[root@node1 ~]# mkdir /backup
[root@node1 ~]# cp -r /mnt/data/ /backup/
[root@node1 ~]# docker cp kingbase:/home/kingbase/install/ /backup/

bash 复制代码

#重新创建容器 + 恢复备份
[root@node1 ~]# docker rm -f kingbase
kingbase
[root@node1 ~]# docker ps -a
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES



步骤 1：#重新创建和原配置一致的容器（核心）
#用原来的启动参数重新创建容器（先不启动数据库，仅创建容器）：
docker run -tid --privileged \
-p 4321:54321 \
-v /mnt/data:/home/kingbase/userdata/ \
-e NEED_START=no \
-e DB_USER=kingbase \
-e DB_PASSWORD=123456 \
-e DB_MODE=mysql \
--name kingbase \
kingbase:v1 /usr/sbin/init

#注意：把 NEED_START=yes 改为 no，避免容器创建时自动启动数据库（此时数据 / 程序还没恢复，启动会报错）。





步骤 2：#恢复程序目录（从宿主机备份到新容器）
#1.清空新容器内默认的程序目录（避免冲突）
[root@node1 ~]# docker exec -it kingbase rm -rf /home/kingbase/install/
#2.从宿主机备份恢复程序目录
[root@node1 ~]# docker cp /backup/install/ kingbase:/home/kingbase/
#3.修复程序目录权限
[root@node1 ~]# docker exec -it kingbase /bin/bash
[kingbase@1fefb4bc37d7 ~]$ sudo su
[root@1fefb4bc37d7 ~]#
[root@1fefb4bc37d7 ~]# chown -R kingbase:kingbase /home/kingbase/install/
[root@1fefb4bc37d7 ~]# chmod -R 755 /home/kingbase/install/




步骤 3：#恢复数据目录（挂载模式，直接恢复宿主机）
#1.清空宿主机挂载目录（/mnt/data）的旧数据
[root@node1 ~]# rm -rf /mnt/data/*
#2.拷贝 /mnt/data
[root@node1 ~]# cp -r /backup/data/ /mnt/
#3.修复数据目录权限
#宿主机权限
[root@node1 ~]#  chown -R root:root /mnt/data/ 
#容器内权限
[root@1fefb4bc37d7 ~]# chown -R kingbase:kingbase /home/kingbase/userdata/
  




步骤 4：#启动数据库并验证（和你原验证步骤一致）
# 1. 进入容器启动数据库
[kingbase@1fefb4bc37d7 ~]$ sys_ctl -D /home/kingbase/userdata/data start
# 2. 验证数据库是否正常（核心验证步骤）
[kingbase@1fefb4bc37d7 ~]$ ksql
Type "help" for help.

kingbase=# select * from t1;
 id
----
  1
  2
  3
(3 rows)
#3.（可选）把 NEED_START 改回 yes，确保容器重启后自动启动数据库
#需修改容器启动参数（或直接重启容器时指定）
[root@node1 ~]# docker rm -f kingbase

# 重新创建容器，改回 NEED_START=yes
docker run -tid --privileged \
-p 4321:54321 \
-v /mnt/data:/home/kingbase/userdata/ \
-e NEED_START=yes \
-e DB_USER=kingbase \
-e DB_PASSWORD=123456 \
-e DB_MODE=mysql \
--name kingbase \
kingbase:v1 /usr/sbin/init

#再次验证
[root@node1 ~]# docker exec -it kingbase /bin/bash
