elasticsearch集群一键部署安装

1.前提条件

机器已经配置ssh无密码登录

2.安装包制作

到官网下载elasticsearch的安装包，根据下面的要求修改配置，并且替换掉。(测试安装包为elasticsearch-2.3.4)

重新打包成.tar.gz。如果安装包不一致，脚本也要做相应的修改。

elasticsearch.yml

 把所有的都注释掉，只保留下面几个，不知道为何，请在每行前面加上一个空格，注意保存字符格式为utf-8。

 cluster.name: escluster

 node.name: xx

 path.data: /data/es

 network.host: xx

 discovery.zen.ping.unicast.hosts: ["xx","xx","xx"]

 discovery.zen.minimum_master_nodes: 2

把上面的内容更换如下：

 cluster.name: escluster

 shNameHost

 path.data: shESDIR

 shNetHost

 discovery.zen.ping.unicast.hosts: [shHost]

 discovery.zen.minimum_master_nodes: 2

3.一键安装脚本编写

新增配置文件conf.properties，内容如下：

#安装目录install_dir=/usr/local/tinstall

#es数据目录es_dir=/data/es#es节点es_nodes=node1 node2 node3

添加安装脚本install-es.sh,内容如下：

#!/bin/bashfile_name="./conf/conf.properties"#安装目录install_dir=`cat ${file_name} | grep install_dir`install_dir=${install_dir#*=}#es数据目录es_dir=`cat ${file_name} | grep es_dir`es_dir=${es_dir#*=}#es节点es_nodes=`cat ${file_name} | grep es_nodes`es_nodes=${es_nodes#*=}home=`env | grep ^HOME= | cut -c 6-`this_host=`hostname`mkdir_cmd="mkdir ${install_dir}"es_config="${home}/elasticsearch-2.3.4/config/"adduser="adduser es"chownes="chown es:es -R ${install_dir}/elasticsearch-2.3.4"rmtmpes="rm -rf ${home}/elasticsearch-2.3.4"echo "Elasticsearch开始安装..."echo "${this_host}节点解压zookeeper..."tar -xzvf ./app/elasticsearch-2.3.4.tar.gz -C  $homehosts=""for node in ${es_nodes[*]}dohosts=${hosts}"\"${node}\","doneecho ${es_config}sed -i "s/shHosts/${hosts%?}/g" ${es_config}elasticsearch.ymlsed -i "s/shESDIR/${es_dir//\//\\/}/g" ${es_config}elasticsearch.ymlnode_value="shNameHost"net_value="shNetHost"for node in ${es_nodes[*]}doecho $nodesed -i "s/${node_value}/node.name: ${node}/g" ${es_config}elasticsearch.ymlsed -i "s/${net_value}/network.host: ${node}/g" ${es_config}elasticsearch.ymlnode_value="node.name: ${node}"net_value="network.host: ${node}"if test "$node" == "$this_host"then$mkdir_cmdcp -r ${home}/elasticsearch-2.3.4 ${install_dir}$adduser$chowneselseecho "${node}节点安装es..."ssh -t -p 22 root@$node $mkdir_cmdscp -r ${home}/elasticsearch-2.3.4 ${node}:${install_dir}/ssh -t -p 22 root@$node $adduserssh -t -p 22 root@$node $chownesfidone$rmtmpesecho "安装es成功！"

编写脚本完成后，为脚本授权chmod +x install-es.sh

运行./install-es.sh
