influxdb 2.0.3 tar.gz的安装与配置

下载地址：https://dl.influxdata.com/influxdb/releases/influxdb2-2.0.3_linux_amd64.tar.gz

### 解压
[root@jyzbdb2 soft]# tar -zxf influxdb2-2.0.3_linux_amd64.tar.gz

### 设置环境变量
[root@jyzbdb2 influxdb2-2.0.3_linux_amd64]# vim /etc/profile
...
export PATH=$PATH:/app/soft/influxdb2-2.0.3_linux_amd64
...

### 使环境变量生效
[root@jyzbdb2 influxdb2-2.0.3_linux_amd64]# source /etc/profile

方式一：直接在终端中启动（该方式启动后，退出终端进程也随之终止，原因不明）

[root@jyzbdb2 influxdb2-2.0.3_linux_amd64]# nohup influxd >> /app/soft/influxdb2-2.0.3_linux_amd64/influx.log 2>&1 &

方式二：设置成服务启动

### 添加 influxdb 用户，用于启动 influxdb 服务
[root@jyzbdb2 influxdb2-2.0.3_linux_amd64]# groupadd influxdb
[root@jyzbdb2 influxdb2-2.0.3_linux_amd64]# useradd -g influxdb -s /bin/false influxdb

### 新增 influxdb 配置文件（这个文件主要用于 influxdb 的优化；如果没有性能问题，也可以不用配置）
[root@jyzbdb2 influxdb2-2.0.3_linux_amd64]# vim config.yml
storage-cache-max-memory-size: 4294967296

### 修改文件的权限
[root@jyzbdb2 influxdb2-2.0.3_linux_amd64]# chown -R influxdb:influxdb /app/soft/influxdb2-2.0.3_linux_amd64

### 新增系统服务的启动文件
### ExecStart后面的参数可以不加，也可以根据实际更改。具体参考：https://docs.influxdata.com/influxdb/v2.0/reference/config-options
[root@jyzbdb2 influxdb2-2.0.3_linux_amd64]# vim /usr/lib/systemd/system/influxdb.service

### 查看 token（客户端一般通过token进行操作）
[root@jyzbdb2 influxdb2-2.0.3_linux_amd64]# cat /root/.influxdbv2/configs
[default]
  url = "http://localhost:8086"
  token = "qPhb-sP__WM3w0U_nhJIYIcfDB0Q1yJ26PqiqwE9_8wL0LrAXoTjm4cT1j0hC4wGWUJsu4BSN-5bev_nS4GRmA=="
  org = "copote"
  active = true

8086 端口：使用该端口与influxdb客户端进行数据交互。

# 开放端口
firewall-cmd --zone=public --add-port=8086/tcp --permanent
# 配置立即生效
firewall-cmd --reload
# 查看防火墙所有开放的端口
firewall-cmd --zone=public --list-ports
