linux安装elasticsearch

 

1 安装jdk

具体看 http://www.cnblogs.com/php-linux/p/8757783.html

 

2 下载最新版的 zip

https://www.elastic.co/cn/downloads/elasticsearch

3 解压

unzip elasticsearch-6.2.3.zip

4 移动

mv elasticsearch-6.2.3 /usr/local/es

5 启动 

提示不能以root用户执行 

useradd es  
passwd es  

为es用户添加sudo权限

visudo 

找到root 复制后改为es

 

 再次启动

估计是权限问题 

sudo chmod 777 -R /usr/local/es

再启动

 访问 http

 查看ip地址

访问

http://192.168.33.30:9200/ 

提示无法访问

 vim /usr/local/es/config/elasticsearch.yml

 

再次重启  

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

解决:切换到root用户,编辑limits.conf 添加类似如下内容

vi /etc/security/limits.conf 

添加如下内容:

* soft nofile 65536

* hard nofile 131072

* soft nproc 2048

* hard nproc 4096

 

[2]: max number of threads [1024] for user [es] is too low, increase to at least [4096]

解决:切换到root用户,进入limits.d目录下修改配置文件。

vi /etc/security/limits.d/90-nproc.conf 

修改如下内容:

* soft nproc 1024

#修改为

* soft nproc 4096

 

[3]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

解决:切换到root用户修改配置sysctl.conf

vi /etc/sysctl.conf 

添加下面配置:

vm.max_map_count=655360

并执行命令:

sysctl -p

 

[4]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

 

问题原因:因为Centos6不支持SecComp,而ES5.2.1默认bootstrap.system_call_filter为true进行检测,所以导致检测失败,失败后直接导致ES不能启动。详见 :https://github.com/elastic/elasticsearch/issues/22899

 

解决方法:在elasticsearch.yml中配置bootstrap.system_call_filter为false,注意要在Memory下面:
bootstrap.memory_lock: false
bootstrap.system_call_filter: false

 

重启es 异常

ERROR: [1] bootstrap checks failed
[1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured
修改
elasticsearch.yml
取消注释保留一个节点
cluster.initial_master_nodes: ["node-1"]
这个的话,这里的node-1是上面一个默认的记得打开就可以了

最终终于启动了

访问ip
