The configuration above, encountered a pit, my card for two days, I go. . . .

At first I placeholder_db_dir is configured became /usr/local/etc/logstash-5.6.0, which is the root of logstash, who become like this actually configured to do so, a variety of all kinds of cereal Baidu song, obviously with others the configuration is the same, I is not synchronized went es. Almost died mysteriously last tried to modify a bit placeholder_db_dir, actually can, and vomiting blood. . .
