1. Environmental preparation
Logstash relies on JDK1.8, so please make sure that JDK1.8 has been installed and configured on the machine before installation.
You can refer to my article
Installation in Linux environment for installation
2. Download address
https://www.elastic.co/cn/downloads/logstash
Choose the consistent version according to your ES and kibana version to install
Three, download and install
download
wget https://artifacts.elastic.co/downloads/logstash/logstash-6.3.2.tar.gz
Unzip and move to the /usr/local folder and change the name
tar -xf logstash-6.3.2.tar.gz
mv logstash-6.3.2 /usr/local/
cd /usr/local/
mv logstash-6.3.2/ logstash
Four, modify the configuration
cd logstash/
vim config/logstash.yml
Modify http.host: "127.0.0.1" to http.host: "0.0.0.0", and open the access permission of port 9600 on the cloud server
Five, test
./bin/logstash -e 'input {stdin {}} output{stdout{}}'
There are two options for running logstash configuration file:
Option 1: Use bin/logstash -e (configuration content is relatively simple, you can write one line, you can directly run the configuration file on the Linux command line to collect data)
such as:/ bin/logstash -e'input {stdin {}} output{stdout{}}'
keyword explanation:
input: configuration input
stdin: indicates command line data, if it is a file, it is file. (It can also be other input)
output: configuration output
stdout: indicates command line output
The meaning of this configuration file: any content input on the command line is collected and processed by logstash, and then output on the command line
方案二：编写一个配置文件，使用 bin/logstash -f 运行该配置文件（./bin/logstash -f test.conf）
vim /config/test.conf
