Elasticsearch 开机自启动

1.环境

1.linux：centos7(vmware 虚拟机)

2.jdk：jdk11(elasticsearch 默认推荐使用jdk11 启动)，安装路径： /usr/local/java/jdk

3.elasticsearch: 版本7.2 ，安装路径： /usr/local/elasticsearch

 

2.创建脚本

在  /etc/init.d  目录下，创建脚本文件 elasticsearch

cd /etc/init.d/

vim elasticsearch

 

插入内容，其中 elasticsearch 启动用户（elasticsearch 为了安全考虑，禁止使用root权限启动），java 安装路径， elasticsearch 安装路径使用实际的安装地址

#!/bin/bash
#chkconfig: 2345 80 05
#description: elasticsearch

export JAVA_HOME=/usr/local/java
export JAVA_BIN=$JAVA_HOME/bin
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME JAVA_BIN PATH CLASSPATH

ES_HOME=/usr/local/elasticsearch
ES_BIN=$ES_HOME/bin

printct() 
{
    i=0
    str='#'
    ch=('|' '\' '-' '/')
    index=0
    while [ $i -le 25 ]
    do
        printf "elasticsearch :"
            printf "[%-25s][%d%%][%c]\r" $str $(($i*4)) ${ch[$index]}
            str+='#'
            let i++
            let index=i%4
            sleep 0.1
    done
    printf "\n"
}

case "$1" in
start)
    es_start_pid=`ps -aux | grep elasticsearch | grep -v grep | grep 'java' | awk '{print $2}'`
    if [ $es_start_pid ]
    then
        echo "-ERROR: elasticsearch is running,not start again......"
    else
        su - es<<!    
        sh $ES_BIN/elasticsearch -d -p pid
!
        printct
        echo "start success......"
    fi
    ;;

stop)
    es_stop_pid=`ps -aux | grep elasticsearch | grep -v grep | grep 'java' | awk '{print $2}'`
    if [ $es_stop_pid ]
    then
        kill -9 $es_stop_pid
        printct
        echo "stop success......"
    else
        echo "-ERROR：The elasticsearch is not running, please start it first......"
    fi    
    ;;

restart)
    $0 stop
    sleep 2s
    $0 start
    ;;

status)
    es_status_pid=`ps -aux | grep elasticsearch | grep -v grep | grep 'java' | awk '{print $2}'`
    if [ $es_status_pid ]
    then
        echo "elasticsearch running......"
        echo "PID: " $es_status_pid
    else
        echo "elasticsearch not running......"
    fi
    ;;
    
*)
    echo "-ERROR: \"$1\" not found"
    echo "-USE: service elasticsearch [ start|stop|restart|status ]"
    ;;
esac

exit $?

 

3.设置开机自启动

在  /etc/init.d  目录下赋予新创建的elasticsearch文件执行权限

chmod +x elasticsearch

 

添加到开机启动任务

chkconfig --add elasticsearch

 

重启机器

shutdown -r now

 

检测elasticsearch是否自启

ps -ef|grep elasticsearch

 

 

浏览器输入ip和端口号查看elasticsearch 是否启动了

http://192.168.1.61:9200

我的虚拟机ip：192.168.1.61
elasticsearch 默认端口9200 和 9300
-- elasticsearch 9200 客户端交互端口，9300集群之间通信的端口

服务启动正常，elasticsearch 开机自启动成功！
