### 2.编译

#### 2.1下载源码

```bash
[root@b156873121b1 opt]# git clone https://github.com/elastic/logstash.git

[root@b156873121b1 logstash]# git checkout v6.8.4
Note: switching to 'v6.8.4'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

git switch -c <new-branch-name>

Or undo this operation with:

git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at 1e4628fc5 syntax fix

### 4.问题解决

#### 问题1：

**问题描述：执行启动命令后报：**

```bash
[root@b156873121b1 bin]# ./logstash

**问题分析：**

```bash
lib/ruby/stdlib/ffi/platform/aarch64-linux/需要platform.conf文件，导致代码异常报错。
```

**问题解决：**
