CentOS 7下ElasticSearch集群搭建案例

  Elasticsearch-5.0.1.tar.gz
  node-v4.2.2-linux-x64.tar.gz

  yum -y install java-1.8*  java -version   #检查 java 是否安装成功 

    关闭防火墙
        systemctl stop firewalld
        systemctl diable firewalld
    关闭 selinux
        sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config   #需要重启系统 

  配置 hostname
        sed -i 's/localhost/es1/g' /etc/hostname     sed -i 's/localhost/es1/g' /etc/hostname

  配置 hosts vi /etc/hosts #添加一下内容      172.16.81.133 es1      172.16.81.134 es2

        useradd elasticsearch
        passwd elasticsearch   #然后输入两次密码即可！

         tar -zxvf elasticsearch-5.0.1.tar.gz
         mv elasticsearch-5.0.1 elasticsearch5
         cd elasticsearch5

         mkdir -p es
         mkdir -p es/data
         mkdir -p es/logs

            cd /opt/elasticsearch5/config
            vi elasticsearch.yml
            es1 配置文件如下：cluster.name: es-cluster    #集群名，不同名称代表不同集群
                node.name: es1    #节点名称，自定义
                path.data: /opt/elasticsearch5/es/data    #数据路径
                path.logs: /opt/elasticsearch5/es/logs    #日志路径
                bootstrap.memory_lock: false    #关闭锁内存
                network.host: 172.16.81.133    #绑定 IP 地址
                http.port: 9200    #绑定端口
                discovery.zen.ping.unicast.hosts: ["es1", "es2"]    #集群列表，类型数组，可以是 IP 或域名
                discovery.zen.minimum_master_nodes: 2    #节点数不能超过节点总数量
                http.cors.enabled: true    #开启 http 网络节点发现
                http.cors.allow-origin: "*"    #允许所有同网段节点发现
            es2 配置文件如下：cluster.name: es-cluster    #集群名，不同名称代表不同集群
                node.name: es2    #节点名称，自定义
                path.data: /opt/elasticsearch5/es/data    #数据路径
                path.logs: /opt/elasticsearch5/es/logs    #日志路径
                bootstrap.memory_lock: false    #关闭锁内存
                network.host: 172.16.81.134    #绑定 IP 地址
                http.port: 9200    #绑定端口
                discovery.zen.ping.unicast.hosts: ["es1", "es2"]    #集群列表，类型数组，可以是 IP 或域名
                discovery.zen.minimum_master_nodes: 2    #节点数不能超过节点总数量
                http.cors.enabled: true    #开启 http 网络节点发现
                http.cors.allow-origin: "*"    #允许所有同网段节点发现 

            vi /etc/security/limits.conf    #添加以下内容
                * soft nofile 65536
                * hard nofile 131072
                * soft nproc 2048
                * hard nproc 4096
            vi /etc/sysctl.conf 
                添加下面配置：vm.max_map_count=655360
                并执行命令：sysctl -p

chown -R elasticsearch:elasticsearch elasticsearch5

            su - elasticsearch
            cd /opt/elasticsearch5/bin
            ./elasticsearch  #观察输出信息
            ./elasticsearch &    #后台运行 

            netstat -lntp
            结果：tcp        0      0 0.0.0.0:9100            0.0.0.0:*               LISTEN      8892/grunt                  
            tcp6       0      0 172.16.81.133:9200      :::*                    LISTEN      5250/java           
            tcp6       0      0 172.16.81.133:9300      :::*                    LISTEN      5250/java           
            存在 9100、9200、9300 上述上个端口即可！
