在Linux环境下快速部署Elasticsearch-6.4.2

总结一下他人的劳动成果
CentOS7 linux 安装 jdk、tomcat + 配置 tomcat 开机启动 + tomcat 快捷启动命令
Linux下如何查看tomcat是否启动
elasticsearch6.6.0安装配置及elasticsearch-head插件安装
Linux（CentOS）安装Node.JS和npm的两种方式（yum安装和源码安装）

查看Tomcat是否以关闭

#ps -ef|grep java

开启Tomcat

#cd bin
#./startup.sh

安装elasticsearch服务

#vim elasticsearch.yml
#chmod -R 775 elasticsearch
#chown -R elsearch:elsearch  elasticsearch-6.4.2/
#./elasticsearch-6.4.2/bin/elasticsearch
#vim /etc/security/limits.conf
#vim /etc/profile
#source /etc/profile
#sysctl -w vm.max_map_count=262144
#sysctl -a | grep "vm.max_map_count"
#node -v //查看nodejs的版本
#npm -v //查看npm的版本

启动elasticsearch-head-master

#git clone git://github.com/mobz/elasticsearch-head.git
#grunt -version
#grunt server &

开启elasticsearch服务

#su - elasticsearch //切换用户
#./elasticsearch &

查看elasticsearch的进程

#ps -aux|grep elasticsearch
#ps -aux|grep 9300
#netstat -natpl | grep 9300

Linux环境下安装Elasticsearch-PHP

#mkdir esphp
#vim composer.json
#composer install --no-dev
#curl -s http://getcomposer.org/installer | php
#chmod -R 777 esphp/
#su - elasticsearch
#php composer.phar install --no-dev

ERROR！！！
centos 6.5 max file descriptors [65535] for elasticsearch process is too low,increase to at least [65536]
max file descriptors [65535] for elasticsearch process likely too low, increase to at least [65536]
