rsylog 保存到 sqlite

一、编译 rsylog

由于系统自带的 rsylog 默认是没有启用保存到数据库的模块的，因此我们需要手动编译安装 rsylog：

# 1. 下载 rsylog 源码
wget https://www.rsyslog.com/download/files/download/rsyslog/rsyslog-8.2208.0.tar.gz

# 2. 解压
tar xvf rsyslog-8.2208.0.tar.gz

# 3. 配置
cd rsyslog-8.2208.0/
./configure --enable-libdbi --enable-mysql

# 4. 编译安装
make && make install

编译过程中可能会遇到环境缺失错误，下面列举一下自己编译过程中遇到的错误：

error:
config.status: error: Something went wrong bootstrapping makefile fragments
    for automatic dependency tracking.  Try re-running configure with the
    '--disable-dependency-tracking' option to at least be able to build
    the package (albeit without support for automatic dependency tracking).

solution:
apt install make

```
apt-get install libmysqlclient-dev
```

apt install libdbd-sqlite3
