Step 1: Install the JDK 1.8 version of the above and in view JDK command
java -version
Step two: Download ElasticSearch Download tar.gz
1. Download https://elasticsearch.cn/download/
2, download time off your VPN, otherwise the download is very slow
under 3, download good, the installation package uploaded to the / usr / local directory
The third step: Extract Configuration
1, extract
tar -xzvf elasticsearch-7.4.2-linux-x86_64\ .tar.gz
2, moves ElasticSearch file directory, modify the configuration file vim config / elasticsearch.yml, add the following configuration at the end:

Configuration files in server memory about elasticsearch-7.4.1 / config / jvm.options
There is a problem, I set it to 128m, start no problem. When I add a few worth the time inside. On the error (out of memory), so this should pay attention
vim config/jvm.options
-Xms128m
-Xmx128m

Other: background boot
1 Start
./elasticsearch -d
2, shut down, first find the process ID, then -9 xxx the kill
PS -ef | grep Elastic
