1、设置服务器GPG密钥

wqbboy@onlyofficed:/opt$ sudo sh -c 'curl https://packages.fluentbit.io/fluentbit.key | gpg --dearmor > /usr/share/keyrings/fluentbit-keyring.gpg'
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  3175  100  3175    0     0   4818      0 --:--:-- --:--:-- --:--:--  4817

2.导出您的 ubuntu 版本名称
在 Ubuntu 上，您需要将 APT 服务器条目添加到源列表中，请在 /etc/apt/sources.list 文件底部添加以下内容 - 确保将 CODENAME 设置为您的特定 Ubuntu 版本名称（例如 Ubuntu 22.04.2 的 jammy）:

首先使用如下命令获取 release name：

wqbboy@onlyofficed:/opt$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 22.04.5 LTS
Release:        22.04
Codename:       jammy

或者执行如下命令：

wqbboy@onlyofficed:/opt$ cat /etc/os-release
PRETTY_NAME="Ubuntu 22.04.5 LTS"
NAME="Ubuntu"
VERSION_ID="22.04"
VERSION="22.04.5 LTS (Jammy Jellyfish)"
VERSION_CODENAME=jammy
ID=ubuntu
ID_LIKE=debian
HOME_URL="https://www.ubuntu.com/"
SUPPORT_URL="https://help.ubuntu.com/"
BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"
PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
UBUNTU_CODENAME=jammy

让我们将其导出到环境变量中：

wqbboy@onlyofficed:/opt$ export CODENAME="jammy"

3、更新 sources lists

wqbboy@onlyofficed:/opt$ echo "deb [signed-by=/usr/share/keyrings/fluentbit-keyring.gpg] https://packages.fluentbit.io/ubuntu/$CODENAME/ \
  $CODENAME main" | sudo tee /etc/apt/sources.list.d/fluentbit.list
  

输出：

deb [signed-by=/usr/share/keyrings/fluentbit-keyring.gpg] https://packages.fluentbit.io/ubuntu/jammy/   jammy main

4.安装 Fluent Bit

sudo apt-get install fluent-bit

使用 systemd 启动 Fluent Bit

# Start Fluent Bit
sudo systemctl start fluent-bit
# Enable Fluent Bit to start on boot
sudo systemctl enable fluent-bit
# Check the status of Fluent Bit
sudo systemctl status fluent-bit

6.配置 Fluent Bit 发送日志到 OpenObserve 默认配置文件位于：/etc/fluent-bit/fluent-bit.conf，可以使用 vim 编辑该文件。我们来采集 /var/log 下面的日志，在 fluent-bit.conf 文件中添加如下配置：

[INPUT]
    Name              tail
    Path              /var/log/*.log
    Parser            docker
    Tag               logs.*
    Refresh_Interval  5
    Rotate_Wait       5
    Mem_Buf_Limit     5MB
    Skip_Long_Lines   On

配置完了 INPUT 部分，我们来配置 OUTPUT 部分，将日志发送到 OpenObserve：

   [OUTPUT]
    Name http
    Match *
    URI /api/justprabhat_organization_1010/default/_json
    Host api.openobserve.ai
    Port 443
    tls On
    Format json
    Json_date_key    _timestamp
    Json_date_format iso8601
    HTTP_User youremail@yourdomain.com
    HTTP_Passwd qatj1wfZ890Q5Sk123k1
    compress gzip

OpenObserve 是一个日志监控平台，该产品相对较新，主张把日志存储在 S3 上，类似 Loki，所以成本更低，当然，带来的问题是检索能力不如 ElasticSearch。本文来自 OpenObserve 的作者：Prabhat Sharma，所以有这么一个章节讲解 Fluentbit 推送日志给 OpenObserve。Fluent Bit 在日志采集领域使用广泛，可以转发到 Logstash、Fluentd、ElasticSearch、Kafka 等多种后端。原文地址：https://openobserve.ai/blog/setup-fluent-bit-on-ubuntu-for-efficient-log-forwarding
配置完了 fluent-bit.conf 文件后，重启 Fluent Bit 服务：

 

sudo systemctl restart fluent-bit

使用以下命令检查服务的状态：

  sudo systemctl status fluent-bit
  

如果有任何错误，您可以使用以下命令检查它们： journalctl -u fluent-bit.service

pgsql启动后执行psql显示报错：

 psql: error: connection to server on socket "/var/run/postgresql/.s.PGSQL.5432" failed: No such file or directory
Is the server running locally and accepting connections on that socket?  

只需要添加一条软连接：

 ln -s /tmp/.s.PGSQL.5432 /var/run/postgresql/.s.PGSQL.5432
