在上一篇文章“ODA模拟器实验系列之七：创建虚拟化应用程序和数据库”中，我们了解了ODA虚拟化的详细操作。

至此，所有官网文档上的实验就做完了，本文讲述模拟器容器的管理。

之前实验，我们使用的都是19.25版的ODA Simulator。昨天（25年3月17日）正好发布了19.26的新版。今天就用新版试一下，文档参见这里。

登入容器

确定容器名：

$ sudo podman ps --format "{{.Names}}"
odasim-1

登入容器：

$ cd ~/simulator_19.26.0.0.0/
$ ./connectContainer.sh -n odasim-1

登入容器后，此时还没有odaadmin用户，只有在BUI中重设口令登录后，才会自动建立odaadmin用户。

检查模拟器状态

虽然odaadmin用户还未创建，但仍可以检查模拟器状态。

[root@odasim-1 /]# /opt/oracle/dcs/bin/statusOdaStack.sh

如果模拟器没有运行，则按如下方式启动模拟器（只有不正常的时候才做！否则就会像下面一样报错）：

[root@odasim-1 /]# /opt/oracle/dcs/bin/startOdaStack.sh

删除所有的容器

注意，要用root执行。

最初，有一容器：

$ podman ps
CONTAINER ID  IMAGE                        COMMAND         CREATED      STATUS         PORTS                                           NAMES
c3a1b1a7b45f  localhost/odasim_ol8:latest  /usr/sbin/init  3 weeks ago  Up 12 minutes  0.0.0.0:7094->7070/tcp, 0.0.0.0:7095->7093/tcp  odasim-1

先删除：

$ ./deleteOdaSimulatorContainer.sh -i 1
Stop Podman container odasim-1
odasim-1
Delete Podman container odasim-1
odasim-1
Delete podman volume persistent-odasim-1-vol
persistent-odasim-1-vol
+ curl -s -X DELETE http://localhost:9000/api/users/0 -H 'Authorization: Bearer ' -H 'accept: application/json'
+ set +x

再清理：

$ ./cleanup_odasimulator_sw.sh
###################################################################

确认已删除：

# podman ps

安装模拟器容器（单节点模式）

注意，要用root执行。

运行模拟器安装脚本（仅setup）:

$ ./setup_odasimulator_sw.sh noportainer
Running Setup for ODA Simulator

Installing podman engine:

此时还没有容器：

# podman ps
CONTAINER ID  IMAGE       COMMAND     CREATED     STATUS      PORTS       NAMES

创建一个单节点ODA模拟容器odasim-1（时间稍长，耐心等待）：

$ ./createOdaSimulatorContainer.sh -d odasim -t single -o noportainer

在以上输出中，一直输出错误信息Agent is not yet ready。只好Ctrl+C中断。

似乎不影响，报成功了：

^C

容器有了。只有一个容器，说明是单机模式：

$ podman ps
CONTAINER ID  IMAGE                        COMMAND         CREATED        STATUS        PORTS                                           NAMES

这是一台全新的ODA模拟器，用BUI试了下，是初始的状态。所有的实验可以重新开始了。

安装模拟器容器（HA模式）

先删除和清理之前的所有容器：

./deleteOdaSimulatorContainer.sh -i 1
./cleanup_odasimulator_sw.sh

创建2节点ODA（即HA模式）模拟器：

./setup_odasimulator_sw.sh noportainer
./createOdaSimulatorContainer.sh -d odasim -t ha -o noportainer

要创建2个容器，时间较长。最后仍然出现了DCS Agent的错误，只好Ctrl+C中断。

成功创建2个容器：
