es7.4安装

环境:

OS:Centos 7

ES:7.4.2

1.下载二进制安装包
我这里下载的是:elasticsearch-7.4.2-linux-x86_64.tar.gz

2.解压缩并创建数据目录
[root@localhost soft]# tar -xvf elasticsearch-7.4.2-linux-x86_64.tar.gz
[root@localhost soft]# mv elasticsearch-7.4.2 /opt/
[root@localhost soft]#cd /opt/elasticsearch-7.4.2


3.创建用户
因为启动es不能在root用户下启动,所以要事先创建非root用户
[root@localhost opt]# useradd esuser
[root@localhost opt]# chown -R esuser.esuser ./elasticsearch-7.4.2/


4.修改配置文件
[esuser@localhost config]$ more elasticsearch.yml
##集群名称
cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#节点名称
node.name: node-1
# Path to directory where to store the data (separate multiple locations by comma):
#数据目录
path.data: /opt/elasticsearch-7.4.2/data
#日志目录
path.logs: /opt/elasticsearch-7.4.2/logs
#
# Set the bind address to a specific IP (IPv4 or IPv6):
## 设置绑定的ip,设置为本机的ip
network.host: 192.168.1.118
# Set a custom port for HTTP:
#端口
http.port: 9200

#设置在集群中的所有节点名称，这个节点名称就是之前所修改的，当然你也可以采用默认的也行，目前是单机，放入一个节点即可
#注意这里，如果目前是单节点的话，一定要修改该值为节点的名称，否则虽然启动成功了，但是通过curl命令向elasticsearch服务中新增数据时，会出现 "master_not_discovered_exception"错误
cluster.initial_master_nodes: ["node-1"]

xpack.security.transport.ssl.enabled: true
xpack.security.enabled: true


5.启动
[esuser@localhost bin]$ ./elasticsearch -d
OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.

6.设置密码

6.8之后的版本，x-pack已经免费，不需要单独破解
[esuser@localhost bin]$ ./elasticsearch-setup-passwords interactive

7.验证
