elasticsearch安裝centos7

1、下載

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.4.1.tar.gz

wget https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v6.4.1/elasticsearch-analysis-ik-6.4.1.zip

2、解壓

tar -zxf elasticsearch-6.4.1.tar.gz -C /opt/

unizp elasticsearch-analysis-ik-6.4.1.zip -d /opt/elasticsearch-6.4.1/plugins/ik/

cd /opt/elasticsearch-6.4.1/

3、添加用戶(因爲不能用root用戶啓動)

useradd elasticsearch

echo "123456" |passwd --stdin elasticsearch 

chown -R elasticsearch:elasticsearch elasticsearch-6.4.1/

4、更改配置文件

cd /opt/elasticsearch-6.4.1/config

vi elasticsearch.yml 

# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
#network.host: 192.168.0.1
network.host: 172.17.0.9,localhost,127.0.0.1
#
# Set a custom port for HTTP:
#
#http.port: 9200
#
# For more information, consult the network module documentation.

5、啓動：

nohup ./elasticsearch &

如果報錯

error: permission denied on key ‘vm.max_map_count’

修改爲：

[root@VM_0_9_centos config]# cat /proc/sys/vm/max_map_count
