CentOS7.9+OpenSearch2.7环境下安装GrayLog5.1

关于OpenSearch

2021 年，开发Elasticsearch 和Kibana的Elastic公司宣布更改许可证，此举旨在禁止云服务商如AWS使用它的软件作为一种服务提供给客户，但这也意味着这两个软件不再是开源软件。发生此事的原因是，Elastic认为云服务商只使用开源软件，而不向开源软件做贡献。

AWS 随后宣布创建ElasticSearch开源分支OpenSearch，承诺会向其提交贡献。如今，OpenSearch 下载量突破1亿，包括AWS员工在内的496名贡献者递交了8760个拉取请求，Adobe也决定在其套件中用OpenSearch取代Elasticsearch，它甚至还进入了DB-Engines 数据库流行度排名前五十。

下面介绍CentOS7.9+OpenSearch2.7环境下安装GrayLog5.1

具体步骤如下

一、安装MongoDB6.0

vim /etc/yum.repos.d/mongodb-org.repo

添加如下行
[mongodb-org-6.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/6.0/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-6.0.asc

mkdir -p /data/opensearch/logs
chown -R /data/opensearch
chown -R opensearch /data/opensearch
sysctl -w vm.max_map_count=262144
