Question

centos7 elasticsearch开机自启动失败

1.在 /etc/systemd/system 创建了 elasticsearch

Unit]
Description=elasticsearch
[Service]
User=elasticsearch
LimitNOFILE=100000
LimitNPROC=100000
# elasticsearch安装路径 （指定自己的安装路径）
ExecStart=/usr/local/elasticsearch/elasticsearch-7.6.2/bin/elasticsearch
[Install]
WantedBy=multi-user.target

sudo systemctl daemon-reload
#设置启动服务
sudo systemctl enable elasticsearch.service
#启动elasticsearch
sudo systemctl start elasticsearch.service

2.在/etc/init.d 创建了 elasticsearch

#!/bin/bash
#chkconfig: 345 63 37
#description: elasticsearch
#processname: elasticsearch-7.3.2
export ES_HOME=/usr/local/elasticsearch-7.3.2
case $1 in
        start)
                su elastic<<!
                cd $ES_HOME
                ./bin/elasticsearch -d -p pid
                exit
!
                echo "elasticsearch is started"
                ;;
        stop)
                pid=`cat $ES_HOME/pid`
                kill -9 $pid
                echo "elasticsearch is stopped"
                ;;
        restart)
                pid=`cat $ES_HOME/pid`
                kill -9 $pid
                echo "elasticsearch is stopped"
                sleep 1
                su elastic<<!
                cd $ES_HOME
                ./bin/elasticsearch -d -p pid
                exit
!
                echo "elasticsearch is started"
        ;;
    *)
        echo "start|stop|restart"
        ;;
esac
exit 0

chmod 777 elasticsearch
chkconfig --add elasticsearch

得到的结果

[root@VM-24-12-centos system]# systemctl status elasticsearch
