news 2026/3/26 18:54:40

Database Manager，这款基于Web的数据库监控工具，以其丰富的界面展示功能而闻名。它能够有效地监控多个集群数据库，确保安全可靠。通过精心设置的管理员用户与普通用户的权限区分，该工具不仅提供了详尽的监控数据，还确保了运维操作的合规性。其主要功能涵盖了集群的导入与监控、主机和实例的运行状态监测、数据库性能的实时把控，以及故障诊断与告警上报等全方位内容。

011. 安装准备

1.1 ► 系统要求

安装Database Manager需要具备一定的硬件与软件环境要求，包括CPU、内存、操作系统以及Python和JDK版本的兼容性。以下为具体要求：

CPU：4核
内存：8G
操作系统：redhat7.5（7.5-x86_64 (RedHat7.5)）
JDK：jdk-8u231-linux-x64.tar.gz
Database Manager：Database_Manager_RHEL.tar.gz
Python：Python 2.7.5

系统需兼容Python 2.7.5版本。Java环境方面，未使用系统预装的Java，已另行安装新版本Java。

1.2 ► 下载指南与注意事项

用户需下载必要的软件包并注意安装时的用户权限及路径设置，尤其是Python和Java的版本兼容性和配置。可以从以下步骤开始：

确保安装用户具备适当的权限。
确认磁盘空间至少为35 GB。

022. 安装步骤

2.1 ► 用户与权限设置

在安装过程中需创建特定用户组和用户并设置适当的权限，以确保安装与后续操作的顺利进行。可以执行以下命令创建用户组：

```bash

groupaddgroup_name>

```

然后，为新用户组添加用户：

```bash

useradd -dhome/user_directory> -ggroup_name> -m dminstalluer

```

确保用户具备执行命令的最小权限范围。

2.2 ► 软件包上传与解压

将Database Manager软件包与JDK上传至服务器并进行解压，为后续的安装步骤做好准备。进入解压后的文件目录，以继续后续安装操作。

2.3 ► DMServer安装过程

按照指定步骤进行DMServer的安装，无需重新安装前需要确保所有组件的正确配置。执行以下命令开始DMServer的安装:

```bash

python install.py install

```

安装过程中，系统会提示输入密码，用户需确保密码安全并牢记，以便后续使用。

033. 安装验证与启动

3.1 ► 安装后验证

通过命令查看DMServer各组件状态，例如执行以下命令：

```bash

python dmserver.py status

```

这将显示出各个组件的状态，确保其正常运作。系统信息提示您完成必要的微服务启动操作，以确保所有组件处于正常运行状态。

3.2 ► Database Manager启动

成功安装后，通过浏览器登录Database Manager，进行数据库管理，并确保安全登录策略的正确配置。首先确保系统已正确绑定IP和端口，在浏览器中输入URL地址即可访问。

044. 卸载流程

卸载Database Manager前需完成以下几个步骤，以确保所有设置均完整且正确。

确认所有设置，并停止Database Manager的运行。
完全验证停止状态，确保无任何组件残留。
使用卸载工具或命令进行卸载，并清理残留文件。

在开始卸载Database Manager之前，建议用户进行充分的数据备份，以防意外情况。
