说明

基于Elasticsearch7.10.2 的 opensearch-1.1.0

硬件服务器

10.168.2.87
10.168.2.88
10.168.2.89

1.环境准备 (每台都需要做)

1.1创建用户(root用户操作)

useradd top

1.2 修改用户密码(root用户操作)

passwd top

1.3 赋予用户sudo权限(root用户操作)

修改命令

chmod -v u+w /etc/sudoers
sed -i 's#.*top.*##g' /etc/sudoers
sed -i 's#root.*ALL=(ALL).*ALL#root  ALL=(ALL)  ALL \ntop   ALL=(ALL)  ALL#g' /etc/sudoers
chmod -v u-w /etc/sudoers

1.4 安全limits文件限制

修改文件
```
vim  /etc/security/limits.conf
```

增加的内容

* soft nofile 65536
* hard nofile 65536

最后几行加上需要增加的部分

1.5 系统文件限制

修改文件
```
vim  /etc/sysctl.conf 
```
增加的内容
```
vm.max_map_count=655360
```

最后几行加上需要增加的部分(最后几行加上)

1.6 载入指定配置

修改文件

[top@node85 .ssh]$ sudo sysctl -p
[sudo] top 的密码：
vm.max_map_count = 655360

结果如图

1.7 重启

执行命令
```
sudo reboot
```

2.opensearch安装参考

官网下载地址

2.1 下载安装包：

执行命令

mkdir /home/top/opensearch
cd /home/top/opensearch
wget http://10.168.2.60:35000/opensearch-1.1.0-linux-x64.tar.gz

3.OpenS安装

3.1 解压OpenS安装包

执行命令

cd /home/top/opensearch
tar -xzvf opensearch-1.1.0-linux-x64.tar.gz

执行命令

mkdir /home/top/opensearch/data -p
mkdir /home/top/opensearch/logs -p

3.3 删除安装包

执行命令

rm -rf opensearch-1.1.0-linux-x64.tar.gz
ln -s opensearch-1.1.0/ opensearch

3.4分发配置及安装目录

执行命令

rsync -avl /home/top/opensearch u86:/home/top 
rsync -avl /home/top/opensearch u87:/home/top

或者

rsync -avl /home/top/opensearch top@10.168.2.86:/home/top/
rsync -avl /home/top/opensearch top@10.168.2.87:/home/top/

4. OpenS节点配置

4.1、 opensearch-master(10.168.2.85 )

cat /home/top/opensearch/opensearch/config/opensearch.yml

# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: opensearch-cluster
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: opensearch-master
node.master: true #专用的主节点
node.data: false # 不是子节点
node.ingest: false # 不是摄取节点 (通道)
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: /home/top/opensearch/data
#
# Path to log files:
#
path.logs: /home/top/opensearch/logs#将集群绑定到特定的 IP 地址
network.host: node85#为集群配置发现主机
discovery.seed_hosts: ["node86","node87","node88"]
cluster.initial_master_nodes: opensearch-master
#禁用安全
plugins.security.disabled: true#discovery.type: cluster

4.2、opensearch-d1 (10.168.2.86)

cat /home/top/elasticsearch-7.10.2/config/elasticsearch.yml

cat /home/top/elasticsearch-7.10.2/config/elasticsearch.yml


#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#

discovery.seed_hosts: ["node85","node86","node87"]
cluster.initial_master_nodes: opensearch-master
#禁用安全
plugins.security.disabled: true

5. 启动OpenS集群

此操作需要在各个节点上运行

/home/top/opensearch/opensearch/bin/opensearch -d -p /home/top/opensearch/pid >/dev/null 2>&1 &

6. 检测是否启动完成集群

[top@localhost ~]$ curl -X GET ‘http://10.168.2.85:9200/’
