1 download Logstash

Download address on the official website: https://www.elastic.co/downloads/logstash

I uploaded it to the server locally, using 5.4.2.

Scp / Users/dalaoyang/downloads/logstash-5.4.2.tar.gz root@ip:/usr/local/tool/logstash-5.4.2.tar.gz2 decompress Logstash

Enter the upload directory to decompress Logstash

Tar-zxvf logstash-5.4.2.tar.gz3 Test Logstash

Enter the logstash-5.4.2 directory

Cd logstash-5.4.2

Here are two simple examples of testing.

3.1 simple output to console bin/logstash-e 'input {stdin {}} output {stdout {}'

As shown in the figure, the startup is successful.

Enter dalaoyang, as shown below

Read the file output to Redisinput {file {type = > "test_log" path = > ["/ Users/dalaoyang/logs/my.log"] start_position = > "beginning" sincedb_path = > "/ dev/null"}} filter {if [type] = = 'test_log' {multiline {pattern = > "^% {TIMESTAMP_ISO8601}" negate = > true what = > previous } output {if [type] = = "test_log" {redis {host = > "ip" port = > "6379" data_type = > "list" key = > "log" # redis password password = > "123456"} # stdout {codec = > rubydebug}}

Start the file location configured above the command bin/logstash-f
