shell启动elasticsearch

方法一：

1.创建脚本文件（以.sh结尾）

# vi elasticsearch.sh

#!/bin/bash
# kconfig: 2345 91 11
# description: elasticsearch
#定义变量
PORT=9200
NAME=elasticsearch
ID=`ps -aux | grep "$NAME" | grep -v "grep" | awk '{print $2}'`
CHECK_PORT=`netstat -tnlp|grep "$PORT"`
ELASTICSEARCH_SERVER=/usr/software/elasticsearch-6.5.4/bin/elasticsearch
RETAVL=0
#检查shelk公共函数库是否存在，存在就加载
FUNCTIONS_PATH=/etc/init.d/functions
[ -f $FUNCTIONS_PATH ]&& source $FUNCTIONS_PATH
#检查文件是否存在并可执行
[ -x $ELASTICSEARCH_SERVER ]|| exit 0

#定义函数
#检查是否执行成功
check(){
	RETAVL=$?
	if 
		[[ "$RETAVL" = 0 ]];then
		action "elasticsearch is $1" /bin/true
	else
		action "elasticsearch is $1" /bin/false	
	fi
}
#启动服务
start(){
	if
		[[ "$CHECK_PORT" != "" ]];then
		echo "elasticsearch already running"
	else
	su - es <

2.增加脚本可执行权限

# chmod +x elasticsearch.sh

 

3.将脚本移动到/etc/rc.d/init.d目录下

# mv elasticsearch.sh /etc/rc.d/init.d

 

4.将脚本添加进开机启动

# cd /etc/rc.d/init.d

# chkconfig –add nginx.sh

# chkconfig nginx.sh on

 

5.查看开机启动列表

# chkconfig --list
