linux下安装elasticsearch5.6.3

1.准备工作

确保系统已经安装jdk1.8及以上版本

2.下载es

下载地址：wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.0.0.tar.gz

3.解压安装

添加用户

useradd elasticsearch

解压

tar xf elasticsearch-5.6.3.tar.gz -C /usr/local

cd /usr/local

设置软链

ln -sv elasticsearch-5.6.3 elasticsearch

 

mkdir -pv /data/elasticsearch/{data,logs}

chown -R elasticsearch.elasticsearch /data/elasticsearch

 

注意：在安装过程中，不建这2个文件夹，启动时会报错，找不到这两个路径。

mkdir -p /usr/local/elasticsearch/plugins


mkdir -p /usr/local/elasticsearch/config/scripts

 

4.修改配置文件

/usr/local/elasticsearch/config/elasticsearch.yml

配置文件中新增内容如下

# 换个集群的名字，免得跟别人的集群混在一起
cluster.name: wlt-es5.0-application   
# 换个节点名字
node.name: node-1
     
path.data: /data/elasticsearch/data
path.logs: /data/elasticsearch/logs

# 修改一下ES的监听地址，这样别的机器也可以访问
network.host: 0.0.0.0
# 默认的就好

http.port: 9200
# 增加新的参数，这样head插件可以访问es
#http.cors.enabled: true
#http.cors.allow-origin: “*"

5.修改系统参数

编辑limit.conf文件  /etc/security/limits.conf

内容如下

*               soft    nproc           65536

*               hard    nproc           65536

*               soft    nofile          65536

*               hard    nofile          65536

继续编辑sysctl.conf文件  /etc/sysctl.conf

内容如下

vm.max_map_count= 262144

编辑完成后执行指令 sysctl -p 使配置生效

注：如果遇到limit.conf文件没有生效的情况下，可执行命令 ulimit -n 65536 临时添加limit.conf中最大打开文件数配置

6.启动es服务

进入/usr/local 路径下，切换至上面添加的elasticsearch用户

指令如下

cd /usr/local

su elasticsearch

启动es

cd /elasticsearch/bin

./elasticsearch

启动完成

启动可能会遇到的问题：

1.elasticsearch安装目录权限不对

遇到启动elasticsearch失败，使用的是专门的用户elasticsearch来启动的，启动日志提示不能加载配置文件：

[elasticsearch@docker bin]$ ./elasticsearch

解决方案

看到“Caused by: java.nio.file.AccessDeniedException: /usr/local/elasticsearch-5.6.3/config/elasticsearch.yml”的提示，

就去检查目录的权限，果然是root:root权限，

使用elasticsearch用户去启动，就报错了。

将目录的权限改成elasticsearch:elasticsearch就好了。

[root@docker ~]# ll /usr/local/
drwxr-xr-x  7 root root       123 9月   7 2017 elasticsearch-5.6.3

[root@docker local]#  chown  -R elasticsearch: elasticsearch elasticsearch-5.6.3
[root@docker local]# ll
drwxr-xr-x  7 elasticsearch  elasticsearch        123 9月   7 2017 elasticsearch-5.6.3
