elasticsearch安装,以及安装过程遇到的问题以及解决方案
安装elasticsearch
- 下载
官方下载地址
或者使用如下命令
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.2.2.tar.gz
curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.2.2.tar.gz- 解压
unzip - 运行
进入到bin目录下
cd bin
./elasticsearch- 第一问题,用户,切换用户
如果你的当前登录用户的权限是root权限,会抛出如下异常

... 6 more解决方案:(切换用户,并将elasticsearch目录变成该用户所有)
adduser 用户名
chown -R 用户名:用户名 目录路径- 在次执行启动命令,日志如下

- 问题二解决方案
进入到config目录下,修改elasticsearch.yml配置文件,找到如下的代码,并释放且修改值
# 这个可以在配置文件中找到
bootstrap.memory_lock: false
# 这个找不到,复制粘贴就好
bootstrap.system_call_filter: false在次启动,问题二也就解决了
- 测试一下访问
集群健康监控
执行命令
curl -XGET http://localhost:9200/_cat/health?v&pretty响应结果
epoch timestamp cluster status node.total node.data shards pri relo init unassign pending_tasks max_task_wait_time active_shards_percent
1519627010 14:36:50 elasticsearch green 1 1 0 0 0 0 0 0 - 100.0%通过上述的一系列问题解决,我们会发现如下问题,本机可以访问.但是局域网外的其他机器无法方法,问题三
- 问题三解决方案
修改elasticsearch.yml配置文件,
network.host: 0.0.0.0参考博客:
