es监控与自动重启

1.安装supervisor进程管理器：

yum install epel-release
yum install -y supervisor

2.修改 supervisor配置

vim /etc/supervisord.conf

设置项目：

minfds=65536
minprocs=4096

3.添加守护进程（共添加3个文件、文件内容按实际适当修改）

添加文件1：/etc/supervisord.d/elasticsearch.ini ，内容：

[program:elasticsearch]

command=/etc/supervisord.d/elasticsearch.sh run

user=es

password=12345678

umask=002

autostart=true

autorestart=true

startsecs=8

startretries=3

redirect_stderr=true

stdout_logfile=/var/log/supervisor/elasticsearch.log

priority=100

添加文件2：/etc/supervisord.d/elasticsearch.sh ，内容：

#!/bin/sh

curl  -H “Content-Type: application/json” -X POST -d @/etc/supervisord.d/elasticMessage.json “https://oapi.dingtalk.com/robot/send?access_token=fewfefewgwefjdnbfhewifhefewfb”;/home/es/elasticsearch-8.2.0/bin/elasticsearch

添加文件3：/etc/supervisord.d/elasticMessage.json ，内容：

{“msgtype”:”text”,”text”:{“content”:”es服务崩溃啦，ElaSticSearch正在自动重新启动！”}}

4.启动supervisor

systemctl start supervisord # 启动supervisord服务

systemctl enable supervisord # 开机自启动
