|
|

|
|
|

```
|
|
|
|
|
|
|
|
|
|
**3、上传文件到$linux$服务器**
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
# 如果没有 rz 命令 先安装
|
|
|
|
|

|
|
|

rz -be
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
**4、新建用户并设置密码**
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
# 创建用户
|
|
|
|
|
useradd elauser
|
|
|
|
|
|
|
|
|
|
# 设置密码 符合密码规范 大写 + 小写 + 数字 + 特殊字符 + 大于八位
|
|
|
|
|
passwd elauser
|
|
|
|
|
|
|
|
|
|
#输入密码：
|
|
|
|
|
DsideaL@123
|
|
|
|
|
|
|
|
|
|
tar -zxvf elasticsearch-9.0.2-linux-x86_64.tar.gz
|
|
|
|
|
chown -R elauser:elauser elasticsearch-9.0.2
|
|
|
|
|
# 进入解压文件并编辑配置文件
|
|
|
|
|
cd elasticsearch-9.0.2/config
|
|
|
|
|
vi elasticsearch.yml
|
|
|
|
|
# 修改数据目录和日志目录
|
|
|
|
|
mkdir -p /usr/local/elasticsearch-9.0.2/data
|
|
|
|
|
mkdir -p /usr/local/elasticsearch-9.0.2/logs
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
设置允许所有IP进行访问，在添加下面参数让$elasticsearch-head$插件可以访问$es$
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
```yaml
|
|
|
|
|
network.host: 0.0.0.0
|
|
|
|
|
http.cors.enabled: true
|
|
|
|
|
http.cors.allow-origin: "*"
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
**5、修改系统配置**
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
# m.max_map_count 值太低
|
|
|
|
|
# 临时解决方案（需要root权限）
|
|
|
|
|
sudo sysctl -w vm.max_map_count=262144
|
|
|
|
|
|
|
|
|
|
# 永久解决方案（需要root权限）
|
|
|
|
|
echo "vm.max_map_count=262144" | sudo tee -a /etc/sysctl.conf
|
|
|
|
|
sudo sysctl -p
|
|
|
|
|
|
|
|
|
|
# 验证是否有效
|
|
|
|
|
sysctl vm.max_map_count
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
**6、启动**
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
# 启动
|
|
|
|

su - elauser
|
|
|
|
|
|
|
|
|
|
cd /usr/local/elasticsearch-9.0.2/bin
|
|
|
|
|
# ./elasticsearch-keystore create
|
|
|
|
|
|
|
|
|
|
# 启动

|
|
|
|
./elasticsearch -d
|
|
|
|
|
|
|
|
|
|
# 访问地址
|
|
|
|
|
https://10.10.14.206:9200
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
弹出 输入账号密码，这里需要重置下密码，再登录 进入安装目录的bin目录下

```bash
|
|
|
|
|
[root@63d697bd738f elasticsearch]# pwd
|
|
|
|
|
/usr/share/elasticsearch
|
|
|
|
|
[root@63d697bd738f elasticsearch]# ./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.9.3/elasticsearch-analysis-ik-7.9.3.zip

## 安装 Kibana
|
|
|
|
|
|
|
|
|
|
- 拉取镜像
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
docker pull kibana:7.9.3
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
- 创建容器
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
# 相关参数
|
|
|
|
|
# 设置 es 请求地址
|
|
|
|
|
# -e ELASTICSEARCH_HOSTS=http://localhost:9200
|
|
|
|
|
# 设置汉化
|
|
|
|
|
# -e I18N_LOCALE=zh-CN
|
|
|
|
|
# 设置时区，否则查询时间需要加 8 个小时
|
|
|
|
|
# -e TZ='Asia/Shanghai'
|
|
|
|
|
|
|
|
|
|
docker run -d --name alex-kibana \
|
|
|
|
|
-p 5601:5601 \
|
|
|
|
|
--net alex-network \
|
|
|
|
|
-e ELASTICSEARCH_HOSTS=http://alex-es:9200 \
|
|
|
|
|
-e I18N_LOCALE=zh-CN \
|
|
|
|
|
kibana:7.9.3
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
- 也可以直接去编辑 kibana 的配置文件
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
# 编辑配置文件
|
|
|
|
|
vi /usr/share/kibana/config/kibana.yml
|
|
|
|
|
|
|
|
|
|
# 适当修改以下配置，因为我们已经将 alex-es 容器和 alex-kibana 容器同时都加入到了 alex-network 网络中，因此这里，我们可以直接通过容器名称进行访问到容器对应的 IP 地址
|
|
|
|
|
elasticsearch.hosts: [ "http://alex-es:9200" ]
|
|
|
|
|
i18n.locale: zh-CN
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
- 测试是否安装成功
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
# 浏览器请求
|
|
|
|
|
127.0.0.1:5601
|
|
|
|
|
```
