Linux安装Elasticsearch(内含es/kibana历史版本下载地址)

1、Elasticsearch下载命令：

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.6.1.tar.gz

es版本最好和kibana版本一致
es历史版本地址: https://www.elastic.co/cn/downloads/past-releases#elasticsearch
kibana历史版本地址: https://www.elastic.co/cn/downloads/past-releases#kibana

2、解压elasticsearch-6.6.1.tar.gz到/usr/local/目录：

tar -avxf elasticsearch-6.6.1.tar.gz -C /usr/local/

3、进入解压后的elasticsearch目录：

1）新建data、logs目录：

mkdir data
mkdir logs

2）修改config/elasticsearch.yml：

vim config/elasticsearch.yml

取消下列项注释并修改:

cluster.name: my-application #集群名称
node.name: node-1 #节点名称
#数据和日志的存储目录
path.data: /usr/local/elasticsearch-6.6.1/data
path.logs: /usr/local/elasticsearch-6.6.1/logs
#设置绑定的ip，设置为0.0.0.0以后就可以让任何计算机节点访问到了
network.host: 0.0.0.0
http.port: 9200 #端口
#设置在集群中的所有节点名称，这个节点名称就是之前所修改的，当然你也可以采用默认的也行，目前是单机，放入一个节点即可
cluster.initial_master_nodes: ["node-1"]

修改完毕后，:wq 保存退出vim

4、准备启动es

进入/bin目录执行命令：

./elasticsearch

我这里出现如下错误：

Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000c5330000, 986513408, 0) failed; error='Cannot allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 986513408 bytes for committing reserved memory.
# An error report file with more information is saved as:
# logs/hs_err_pid22863.log
[root@VM_0_2_centos bin]# 

看来是我这1G的内存太小了啊，elasticsearch使用java的jvm默认是使用1G的内存的，这里我们修改一下内存，直接把内存改到200m
cd 到es目录修改 ./config/jvm.options：

vim ./config/jvm.options 

修改内容:

-Xms200m
-Xmx200m

:wq 保存并退出vim，再次启动es

再次启动出现如下错误：

    [root@VM_0_2_centos elasticsearch-6.6.1]# 

这是不能使用root用户操作，添加一个其他的用户再试试：

[root@VM_0_2_centos elasticsearch-6.6.1]# adduser es
[root@VM_0_2_centos elasticsearch-6.6.1]# passwd es
Changing password for user es.
New password: 
Retype new password: 
passwd: all authentication tokens updated successfully.

改一下es目录所属用户：

[root@VM_0_2_centos elasticsearch-6.6.1]# chown es /usr/local/elasticsearch-6.6.1/ -R

vim 编辑 /etc/security/limits.conf，在末尾加上：

es soft nofile 65536
es hard nofile 65536
es soft nproc 4096
es hard nproc 4096

vim 编辑 vim /etc/security/limits.d/20-nproc.conf，将* 改为用户名（es）：

# Default limit for number of user's processes to prevent
# accidental fork bombs.
# See rhbz #432903 for reasoning.

es          soft    nproc     4096
root       soft    nproc     unlimited

vim 编辑 /etc/sysctl.conf，在末尾加上：

vm.max_map_count = 655360

执行 sysctl -p

[root@VM_0_2_centos ~]# sysctl -p
kernel.printk = 5
vm.max_map_count = 655360
[root@VM_0_2_centos ~]# 

登录刚才新建的es用户，并启动elasticsearch，OK

[root@VM_0_2_centos elasticsearch-7.1.1]# su es
[es@VM_0_2_centos elasticsearch-7.1.1]$ ./bin/elasticsearch -d
