elasticsearch 5.x集群安装

1. 下载

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.5.1.tar.gz

2. 解压

为便于识别，解压后起名 elasticsearch-5.5.1-nodex  , elasticsearch-5.5.1-node1  elasticsearch-5.5.1-node2 elasticsearch-5.5.1-node3

elasticsearch-5.5.1-node1 elasticsearch-5.5.1-node3 安装在一台机器。

3. chown   elasticsearch 不允许root启动

groupadd es

useradd -g es es

cd .......

chown -R es ./

4. 修改sysctl.conf   默认 65530太小，否则启动时会报错

echo "vm.max_map_count=655360" >>/etc/sysctl.conf

sysctl -p

5. 启动

cd ....../bin 

./elasticsearch -d

配置：

node1 :   master 

vim elasticsearch-5.5.1-node1/config/elasticsearch.yml     

bootstrap.system_call_filter: false 必须，否在会报日志路径等权限错误

升级6.1.1坑：

 max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]

vim /etc/security/limits.conf

es hard nofile 65536
es soft nofile 65536

max number of threads [1024] for user [elasticsearch] is too low, increase to at least [2048]

/etc/security/limits.d/90-nproc.conf 

*          soft    nproc     1024

*          soft    nproc     2048
