如何二进制安装Linux集群

概述

本文主要讲解如何二进制安装Linux集群

环境信息

主机名	IP地址	系统
ELK01	10.0.0.40	Ubuntu22.04
ELK02	10.0.0.41	Ubuntu22.04
ELK03	10.0.0.42	Ubuntu22.04

实操

安装JDK（所有节点都需要安装）

ElasticSearch是使用Java语言开发的，所以运行时依赖JDK

安装JDK可以参考这篇文章：https://www.cnblogs.com/huangSir-devops/p/18919758

ElasticSearch版本和Java版本对应关系，可以阅读这篇文章：https://www.elastic.co/support/matrix#matrix_jvm

我们这里安装ELasticSearch7.17.x版本的，我们安装JDK11版本

|     | # 下载 |
|     | [root@master ~]# wget https://mirrors.huaweicloud.com/openjdk/11.0.2/openjdk-11.0.2_linux-x64_bin.tar.gz |
|     | [root@master ~]# ll openjdk-11.0.2_linux-x64_bin.tar.gz |
|     | -rw-r--r-- 1 root root 187513052 Jan 182019 openjdk-11.0.2_linux-x64_bin.tar.gz |
|     |     |
|     | # 解压 |
|     | [root@master ~]# tar -xvf openjdk-11.0.2_linux-x64_bin.tar.gz |
|     |     |
|     | # 创建软连接 |
|     | [root@master ~]# ln -s /root/jdk-11.0.2 /usr/local/jdk11 |
|     | [root@master ~]# ll /usr/local/jdk11 |
|     | lrwxrwxrwx 1 root root 16 Jun 1421:09 /usr/local/jdk11 -> /root/jdk-11.0.2/ |
|     |     |
|     | # 配置环境变量 |
|     | [root@master ~]# vim /etc/profile |
|     | # 根据实际安装路径修改 |
|     | export JAVA_HOME=/usr/local/jdk11/ |
|     | export PATH=$JAVA_HOME/bin:$PATH |
|     | export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar |
|     |     |
|     | # 加载环境变量 |
|     | [root@master ~]# source /etc/profile |
|     |     |
|     | # 验证 |
|     | [root@master ~]# java -version |
|     | openjdk version "11.0.2"2019-01-15 |
|     | OpenJDK Runtime Environment 18.9 (build 11.0.2+9) |
|     | OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode) |

 

配置主机名及添加hosts解析

ELK01节点设置

 

|     |     |
| --- | --- |
|     | [root@master ~]# hostnamectl set-hostname ELK01 |
|     | [root@master ~]# hostname |
|     | ELK01 |

 

ELK02节点设置

 

|     |     |
| --- | --- |
|     | [root@master ~]# hostnamectl set-hostname ELK02 |
|     | [root@master ~]# hostname |
|     | ELK02 |

 

ELK03节点设置

 

|     |     |
| --- | --- |
|     | [root@master ~]# hostnamectl set-hostname ELK03 |
|     | [root@master ~]# hostname |
|     | ELK03 |

 

三台节点都添加hosts解析

 

|     |     |
| --- | --- |
|     | [root@master ~]# vim /etc/hosts |
|     | 10.0.0.40 ELK01 |
|     | 10.0.0.41 ELK02 |
|     | 10.0.0.42 ELK03 |

 

配置时间同步（所有节点都需配置）

 

|     |     |
| --- | --- |
|     | [root@master ~]# ln -svf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime |
|     | #下载ntpdate  工具 |
|     | [root@master ~]# apt -y install ntpdate |
|     | [root@master ~]# ntpdate ntp.aliyun.com |
|     |     |
|     | [root@master ~]# echo "*/5 * * * * /usr/sbin/ntpdate ntp.aliyun.com" > /var/spool/cron/crontabs/root |

 

系统配置（所有节点都需配置）

优化系统参数

 

|     |     |
| --- | --- |
|     | [root@master ~]# vim /etc/sysctl.conf |
|     | # ES 需要大量文件描述符来处理索引和网络连接，建议设置为较高值： |
|     | fs.file-max = 655360 |
|     | # ES 使用 mmap 技术加载索引，需增大虚拟内存区域限制： |
|     | vm.max_map_count = 2147483642 |
|     | # 禁用交换空间(swap分区) |
|     | vm.swappiness = 1 |
|     |     |
|     | # 网络参数优化 |
|     | net.ipv4.tcp_keepalive_time = 600 |
|     | net.ipv4.tcp_keepalive_intvl = 60 |
|     | net.ipv4.tcp_keepalive_probes = 10 |
|     | net.ipv4.tcp_max_syn_backlog = 4096 |
|     | net.core.somaxconn = 4096 |
|     | net.core.netdev_max_backlog = 16384 |
|     | net.core.rmem_max = 262144 |
|     | net.core.wmem_max = 262144 |
|     |     |
|     | # 使参数生效 |
|     | [root@master ~]# sysctl -p /etc/sysctl.conf |
|     |     |
|     | # 查询参数，验证是否生效 |
|     | [root@master ~]# sysctl -q vm.max_map_count |
|     | vm.max_map_count = 2147483642 |

 

创建es存储目录

 

|     |     |
| --- | --- |
|     | [root@master ~]# mkdir -p /data/elasticsearch/ |
|     | [root@master ~]# mkdir -p /var/log/elasticsearch/ |

 

创建es用户

 

|     |     |
| --- | --- |
|     | [root@master ~]# useradd elasticsearch |
|     | [root@master ~]# id elasticsearch |
|     | uid=2002(elasticsearch) gid=2003(elasticsearch) groups=2003(elasticsearch) |
|     |     |
|     | # 授权 |
|     | [root@master ~]# chown elasticsearch:elasticsearch -R /data/elasticsearch/ |
|     | [root@master ~]# chown elasticsearch:elasticsearch -R /var/log/elasticsearch/ |

 

添加es用户的限制

 

|     |     |
| --- | --- |
|     | [root@master ~]# vim /etc/security/limits.conf |
|     | # 最大文件描述符数 |
|     | elasticsearch hard nofile 655360 |
|     | elasticsearch soft nofile 655360 |
|     | # 最大进程数 |
|     | elasticsearch hard nproc 8192 |
|     | elasticsearch soft nproc 8192 |
|     | # 锁定内存限制 |
|     | elasticsearch hard memlock unlimited |
|     | elasticsearch soft memlock unlimited |

|     |     |
|     | # 创建软连接 |
|     | [root@master ~]# ln -s /data/elasticsearch-7.17.26 /usr/local/es7 |
|     | [root@master ~]# ll /usr/local/es7 |
|     | lrwxrwxrwx 1 root root 27 Jun 1421:50 /usr/local/es7 -> /data/elasticsearch-7.17.26/ |

 

修改配置文件

 

|     |     |
| --- | --- |
|     | [root@master ~]# vim /usr/local/es7/config/elasticsearch.yml |
|     | cluster.name: es7 |
|     | path.data: /data/elasticsearch |
|     | path.logs: /var/log/elasticsearch |
|     | network.host: 0.0.0.0 |
|     | http.port: 9200 |
|     | discovery.seed_hosts: ["ELK01", "ELK02", "ELK03"] |
|     | cluster.initial_master_nodes: ["ELK01", "ELK02", "ELK03"] |
|     |     |
|     | # 根据节点名称来进行修改此字段 |
|     | # node.name: ELK01 |
|     | # node.name: ELK02 |
|     | node.name: ELK03 |

 

启动ElasticSearch集群（三个节点都执行）

创建systemd文件

|     | [Unit] |
|     | Description=elasticsearch service |
|     | Documentation=https://www.cnblogs.com/huangSir-devops |
|     | After=network.target auditd.service |
|     |     |
|     | [Service] |
|     | LimitMEMLOCK=infinity |
|     | User=elasticsearch |
|     | ExecStart=/usr/local/es7/bin/elasticsearch |
|     | TimeoutStopSec=0 |
|     | TimeoutStartSec=0 |
|     |     |
|     | [Install] |
|     | WantedBy=multi-user.target |
