一.安装前的准备
1.1 机器分配
以下安装使用 root 用户，搭建集群模式，一共三台机器：
| ip | Meta | Graph | Storage |
| 192.168.5.85 | 1 | 1 | 1 |
| 192.168.5.86 | 1 | 1 | 1 |
| 192.168.5.87 | 1 | 1 | 1 |
1.1 安装目录
nebula 主程序、nebula-console 安装在 /opt 目录
nebula-studio 安装在默认目录（ /usr/local/nebula/nebula-graph-studio ）,我们这里安装指定路径
nebula 的数据文件安装在 /opt/nebula/data/nebula 目录
nebula 的metad数据安装在 /opt/nebula/data/nebula/metd 目录
nebula 的日志文件安装在 /opt/nebula/resource/nebula/storage目录
二 .Nebula 安装部署
2.1 下载安装包
wget https://oss-cdn.nebula-graph.com.cn/package/2.6.1/nebula-graph-2.6.1.el7.x86_64.rpm
2.2 安装 rpm 包
如果不设置安装路径，默认安装路径为 /usr/local/nebula/ ，此处修改为：/opt/nebula-2.6.1
rpm -ivh --prefix=/opt/nebula-2.6.1 nebula-graph-2.6.1.el7.x86_64.rpm
2.3 建立软连接
切换到 /opt 目录，执行以下命令：
ln -s nebula-2.6.1 nebula
2.4 修改配置
配置文件在 /opt/nebula/etc 下：
因为是生产环境，可以将其他的配置文件都删了，只保留带 .production 的配置文件，最后要把 .production 扩展名去掉，保证扩展名都是 .conf 。
2.4.1 nebula-metad.conf配置修改
主要修改点（日志文件路径、日志级别、元数据服务地址、本机 IP、数据文件路径）：
2.4.2 nebula-graphd.conf配置修改
主要修改点（日志文件路径、日志级别、元数据服务地址、本机 IP）：
2.4.3 nebula-storaged.conf配置修改
主要修改点（日志文件路径、日志级别、元数据服务地址、本机 IP、数据文件路径）：
2.5 将 其中一台机器的文件 拷贝到 其余机器

2.7 启动 Nebula
切换到每个机器的 /opt/nebula/scripts 下，执行如下命令：
[root@xuehai-streaming-01 ~]# cd /opt/nebula/scripts
[root@xuehai-streaming-01 scripts]# ll
total 28
-rwxr-xr-x 1 root root 1985 Nov 3 19:15 meta-transfer-tools.sh

4.4 查看下 端口
[root@xuehai-streaming-01 software]# lsof -i:7001
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
node 28471 root 23u IPv4 16403577 0t0 TCP *:afs3-callback (LISTEN)
4.4 访问 Nebula Studio
在浏览器中访问：http://192.168.5.85:7001/
出现以上代表成功了
4.5 输入 graphd 的连接地址及用户名密码
a Host：填写 Nebula Graph 的 Graph 服务本机 IP 地址及端口。格式为
b ip:port ：如果端口未修改，则使用默认端口 9669。
c. 用户名 和 密码：根据 Nebula Graph 的身份验证设置填写登录账号和密码。
c1.如果未启用身份验证，可以填写默认用户名root和任意密码。
c2.如果已启用身份验证，但是未创建账号信息，用户只能以 GOD 角色登录，必须填写root及对应的密码nebula
c3.l如果已启用身份验证，同时又创建了不同的用户并分配了角色，不同角色的用户使用自己的账号和密码登录。
我们这里输入如下，没有开启身份认证
ip:192.1685.85:9669
用户名 ：root
密码 ：root
进入Studio 界面后，可以选择 Space，默认没有 Space，需要单独创建一个
如果能看到如上 图所示的界面，表示已经成功连接到 Nebula Graph 数据库。
那么 可以 创建 scheme【放在后文】
可以进去代表 安装 成功 了
五.依赖安装
5.1 安装 lsof
yum install lsof -y
5.2 安装 Node.js
5.2.1 下载 Node.js
官网下载地址：https://nodejs.org/zh-cn/download/
下载地址：https://nodejs.org/dist/v16.13.0/node-v16.13.0-linux-x64.tar.xz
[root@xuehai-streaming-01 software]# wget https://nodejs.org/dist/v16.13.0/node-v16.13.0-linux-x64.tar.xz
--2021-11-08 12:09:17-- https://nodejs.org/dist/v16.13.0/node-v16.13.0-linux-x64.tar.xz

5.2.2 解压 Node.js
需要分两步解压：
xz -d node-v16.13.0-linux-x64.tar.xz
tar -xvf node-v16.13.0-linux-x64.tar
5.2.3 将 node-v16.13.0-linux-x64 拷贝到 /opt 底下
[root@xuehai-streaming-01 software]# mv node-v16.13.0-linux-x64 ../
5.2.4 对 /opt 底下的 Node 建立软连接
[root@xuehai-streaming-01 opt]# ln -s node-v16.13.0-linux-x64 node
5.2.5 将 Node.js 添加到环境变量
vi /etc/profile
#Node Env
NODE_HOME=/opt/node
PATH=$PATH:$NODE_HOME/bin
export NODE_HOME PATH
5.2.6 使环境变量生效
[root@xuehai-streaming-01 node]# source /etc/profile
5.2.7 验证 Node.js 是否可用
在命令行直接输入：node ，返回信息如下代表成功了：
5.2.8 在 /usr/bin 下建立对 Node.js、npm 的软连接【如过有低版本的要删掉】
[root@xuehai-streaming-01 software]# ln -s /opt/node/bin/node /usr/bin/node
[root@xuehai-streaming-01 software]# ln -s /opt/node/bin/npm /usr/bin/npm
六. 卸载
6.1 用户可以使用以下的命令卸载 Studio
rpm -e nebula-graph-studio-3.1.0.x86_64
6.2 异常处理
6.2.1 如果在安装过程中自动启动失败或是需要手动启动或停止服务，请使用以下命令
手动启动服务
$ bash /usr/local/nebula-graph-studio/scripts/rpm/start.sh
手动停止服务
$ bash /usr/local/nebula-graph-studio/scripts/rpm/stop.sh
6.2.2 如果启动服务时遇到报错报错 ERROR: bind EADDRINUSE 0.0.0.0:7001，用户可以通过以下命令查看端口7001是否被占用。
$ lsof -i:7001
6.2.3如果端口被占用
无法结束该端口上进程，用户可以通过以下命令修改Studio服务启动端口，并重新启动服务。
//修改studio服务启动端口
$ vi config/config.default.js
//修改
...
config.cluster = {
listen: {
port: 7001, // 修改这个端口号，改成任意一个当前可用的即可
hostname: '0.0.0.0',
},
};
...
//重新启动npm
$ npm run start
安装完毕，让我们开启使用之旅吧。详细使用步骤：
