1.安装elasticsearch
初步设计elasticsearch为两个节点
系统初始化(centos7)
#防火墙 systemctl status iptables systemctl status firewalld systemctl stop firewalld systemctl disable firewalld systemctl status firewalld #selinux 关闭 sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config setenforce 0 #打开文件数 sed -i '/# End of file/i* - nofile 65536' /etc/security/limits.conf cat /etc/security/limits.conf ulimit -HSn 65536 ulimit -n #内核参数调整 echo 'net.ipv4.ip_forward = 1' > /etc/sysctl.conf echo 'net.ipv4.tcp_timestamps = 1' >> /etc/sysctl.conf echo 'net.ipv4.tcp_tw_recycle = 1' >> /etc/sysctl.conf echo 'net.ipv4.tcp_fin_timeout = 30' >> /etc/sysctl.conf echo 'vm.max_map_count=262144' >> /etc/sysctl.conf sysctl -p #配置yum源为aliyun cd /etc/yum.repos.d rm -rf * rpm -ivh http://source.zhaolibin.com/scripts/wget-1.14-10.el7_0.1.x86_64.rpm wget -O CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo yum clean all yum makecache
java环境安装
wget http://source.zhaolibin.com/elk/jdk-8u144-linux-x64.tar.gz tar -zxvf jdk-8u144-linux-x64.tar.gz mv jdk1.8.0_144 java mv java /usr/local/ #添加JDK变量环境 echo '#JAVA#'>> /etc/profile echo 'JAVA_HOME=/usr/local/java'>> /etc/profile echo 'CLASSPATH=$JAVA_HOME/lib:$JAVA_HOME/jre/lib'>> /etc/profile echo 'PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin'>> /etc/profile echo 'export PATH CLASSPATH JAVA_HOME'>> /etc/profile source /etc/profile
elasticsearch 安装
mkdir /data/ tar -zxvf elasticsearch-5.5.0.tar.gz -C /data/ ln -s /data/elasticsearch-5.5.0/ /data/elasticsearch #新建用户 useradd elasticsearch echo "123456"|passwd --stdin elasticsearch chown -R elasticsearch.elasticsearch /data/elasticsearch* #修改配置文件 #vim /data/elasticsearch/config/jvm.options #调整 #-Xms3g（设置为合适的大小） #-Xmx3g
elasticsearch 配置文件（暂未做优化）
cluster.name: my-es node.name: es1 network.host: 172.28.50.201 http.port: 9200 http.cors.enabled: true http.cors.allow-origin: "*"
elasticsearch head插件安装
cd /data wget http://source.zhaolibin.com/elk/node-v8.3.0-linux-x64.tar.gz yum install bzip2 -y tar -zxvf node-v8.3.0-linux-x64.tar.gz ln -s /data/node-v8.3.0-linux-x64/ /data/node ln -s /data/node/bin/npm /usr/local/bin/node ln -s /data/node/bin/npm /usr/local/bin/npm npm install -g cnpm --registry=https://registry.npm.taobao.org yum -y install git git clone git://github.com/mobz/elasticsearch-head.git cd elasticsearch-head/ npm install grunt --save-dev
/usr/local/elasticsearch-head/node_modules/grunt/bin/grunt server
