1、系统环境及软件版本

2、安装influxdb2.8

官方安装文档

下载二进制安装包

# Use curl to download the amd64 binary.
curl --location -O \
https://download.influxdata.com/influxdb/releases/v2.8.0/influxdb2-2.8.0_linux_amd64.tar.gz
​

验证密钥文件

# amd64
# Download and import the key
curl --silent --location https://repos.influxdata.com/influxdata-archive.key \
| gpg --import - 2>&1 \
| grep 'InfluxData Package Signing Key <support@influxdata.com>' \
&&
# Download and verify the binary's signature file
curl --silent --location "https://download.influxdata.com/influxdb/releases/v2.8.0/influxdb2-2.8.0_linux_amd64.tar.gz.asc" \
| gpg --verify - influxdb2-2.8.0_linux_amd64.tar.gz \
2>&1 | grep 'InfluxData Package Signing Key <support@influxdata.com>'

输出

gpg: 密钥 7C3D57159FC2F927：公钥 “InfluxData Package Signing Key <support@influxdata.com>” 已导入
gpg: 完好的签名，来自于 “InfluxData Package Signing Key <support@influxdata.com>” [未知]
​

解压二进制文件

tar zxf influxdb2-2.8.0_linux_amd64.tar.gz -C /usr/local

配置环境变量

# 将influxd 软链接到 /usr/local/bin
ln -s /usr/local/influxdb2-2.8.0/influxd /usr/bin/influxd

直接执行influxd启动

创建systemd自启动

sudo tee /etc/systemd/system/influxdb.service <<'EOF'
