1、上传Elastiscsearch安装压缩包到服务器/opt目录上
2、修改内核参数max_map_count
max_map_count包含限制一个进程可以拥有的VMA(虚拟内存区域)的数量
vim /etc/sysctl.conf
在最后添加下面一行
vm.max_map_count = 262144
加载配置生效
sysctl -p
查看当前值
sysctl -a|grep vm.max_map_count
3、解压Elastiscsearch安装包、重命名
cd /opt tar -zxvf elasticsearch-5.6.9.tar.gz mv elasticsearch-5.6.9 elasticsearch
4、创建Elasticsearch用户组、用户、创建日志和数据目录、授权
groupadd elasticsearch useradd elasticsearch -g elasticsearch mkdir {elasticsearch/logs,elasticsearch/data} chown -R elasticsearch:elasticsearch elasticsearch
5、修改配置
vim /opt/elasticsearch/config/elasticsearch.yml
修改里面---Network---这一块的2行配置
network.host: 0.0.0.0 http.port: 9200
6、配置系统配置文件
vim /etc/sysconfig/elasticsearch
添加如下内容，其中路径根据实际情况填写：
################################ # Elasticsearch ################################ # Elasticsearch home directory ES_HOME=/opt/elasticsearch # Elasticsearch Java path JAVA_HOME=/usr/local/jdk # Elasticsearch configuration directory CONF_DIR=/opt/elasticsearch/config # Elasticsearch data directory DATA_DIR=/opt/elasticsearch/data # Elasticsearch logs directory LOG_DIR=/opt/elasticsearch/logs # Elasticsearch PID directory PID_DIR=/opt/elasticsearch # Additional Java OPTS #ES_JAVA_OPTS= # Configure restart on package upgrade (true, every other setting will lead to not restarting) #RESTART_ON_UPGRADE=true ################################ # Elasticsearch service ################################ # SysV init.d # # When executing the init script, this user will be used to run the elasticsearch service. # The default value is 'elasticsearch' and is declared in the init.d file. # Note that this setting is only used by the init script. If changed, make sure that # the configured user can read and write into the data, work, plugins and log directories. # For systemd service, the user is usually configured in file /usr/lib/systemd/system/elasticsearch.service ES_USER=elasticsearch ES_GROUP=elasticsearch # The number of seconds to wait before checking if Elasticsearch started successfully as a daemon process ES_STARTUP_SLEEP_TIME=5 ################################ # System properties ################################ # Specifies the maximum file descriptor number that can be opened by this process # When using Systemd, this setting is ignored and the LimitNOFILE defined in # /usr/lib/systemd/system/elasticsearch.service takes precedence MAX_OPEN_FILES=65536 # The maximum number of bytes of memory that may be locked into RAM # Set to "unlimited" if you use the 'bootstrap.memory_lock: true' option # in elasticsearch.yml. # When using systemd, LimitMEMLOCK must be set in a unit file such as # /etc/systemd/system/elasticsearch.service.d/override.conf. MAX_LOCKED_MEMORY=unlimited # Maximum number of VMA (Virtual Memory Areas) a process can own # When using Systemd, this setting is ignored and the 'vm.max_map_count' # property is set at boot time in /usr/lib/sysctl.d/elasticsearch.conf MAX_MAP_COUNT=262144
7、调大用户的软限制和硬限制的值
vim /etc/security/limits.conf
在最后面添加
* soft nofile 65536 * hard nofile 65536
8、切换用户、启动服务
su elasticsearch cd /opt/elasticsearch/bin ./elasticsearch -d
9、浏览器访问：http://IP:9200，正常会输出一段JSON内容。
备注：
上面配置的端口号9200系统默认不允许进行远程连接，需要在防火墙中设置9200允许远程连接。
