CentOS Sentinel Installation

1、下载

Download地址https://github.com/alibaba/Sentinel/releases

2、安装

提前Create好InstallationPath、Jar包存放File夹、ScriptExecuteFile夹、Logging存放File夹

mkdir /usr/local/ sentinel
mkdir /usr/local/sentinel jar
mkdir /usr/local/sentinel sh
mkdir /usr/local/sentinel log

将sentinel-dashboard-1.8.6.jarExecuteJar包上传至jarFile夹

3、脚本

编写Scriptsentinel.sh，按照自己Path、Version号调整，存放到上面新建的shFile夹中。Script如下：

#!/bin/bash
#这里可替换为你自己的执行程序，其他代码无需更改
SENTINEL_NAME=sentinel-dashboard-1.8.6.jar
#使用说明，用来提示输入参数
usage() {
 echo "Usage: sh sentinel.sh [start|stop|restart|status]"
 exit 1
}

#检查程序是否在运行
is_exist(){
 pid=`ps -ef|grep $SENTINEL_NAME|grep -v grep|awk '{print $2}' `
 #如果不存在返回1，存在返回0 
 if [ -z "${pid}" ]; then
 return 1
 else
 return 0
 fi
}

#启动方法
start(){
 is_exist
 if [ $? -eq "0" ]; then
 echo "${SENTINEL_NAME} is already running. pid=${pid} ."
 else
 nohup java -Dserver.port=9100 -Dcsp.sentinel.dashboard.server=192.168.56.10:9100 -Dproject.name=sentinel-dashboard -jar /usr/local/sentinel/jar/$SENTINEL_NAME > /usr/local/sentinel/log/sentinellog.file 2>&1 &
 #nohup java -jar /usr/local/sentinel/jar/$SENTINEL_NAME > /usr/local/sentinel/log/sentinellog.file 2>&1 &
 echo "${SENTINEL_NAME} start success"
 fi
}

#停止方法
stop(){
 is_exist
 if [ $? -eq "0" ]; then
 kill -9 $pid
 else
 echo "${SENTINEL_NAME} is not running"
 fi
}

#输出运行状态
status(){
 is_exist
 if [ $? -eq "0" ]; then
 echo "${SENTINEL_NAME} is running. Pid is ${pid}"
 else
 echo "${SENTINEL_NAME} is NOT running."
 fi
}

#重启
restart(){
 stop
 start
}

#根据输入参数，选择执行对应方法，不输入则执行使用说明
case "$1" in
 "start")
 start
 ;;
 "stop")
 stop
 ;;
 "status")
 status
 ;;
 "restart")
 restart
 ;;
 *)
 usage
 ;;
esac

进入/usr/local/sentinel/sh/File夹下，ExecuteCommand修改Permissions

chmod +x sentinel.sh

注意：

1、如果直接复制到windows中文本的，注意windows和linx的换行符不同，导致Start失败，可Usagenotepad++中编辑—>文档格式转换—>转换成Unix格式。

2、注意给ScriptSettingsPermissions

4、测试

本地Test是否能够Start

StartsentinelService

sh sentinel.sh start

停止sentinelService

sh sentinel.sh stop

RestartsentinelService

sh sentinel.sh restart

ViewsentinelService状态

sh sentinel.sh status

ServiceStart后，可通过IP+端口+项目名访问Sentinel登录页面

5、自启动

本地Test可通过CommandStart没Problem后，编写StartServicesentinel.service，放到/usr/lib/systemd/systemDirectory，内容如下：

[Unit]
Description=sentinel
After=network.target
 
[Service]
Environment="JAVA_HOME=/usr/local/java/jdk-11.0.10"
Type=forking
ExecStart=/usr/local/sentinel/sh/sentinel.sh start
ExecReload=/usr/local/sentinel/sh/entinel.sh stop
ExecStop=/usr/local/sentinel/sentinel/sh/sentinel.sh restart
PrivateTmp=true
 
[Install]
WantedBy=multi-user.target

重载所有Service

systemctl daemon-reload

Set Auto Start on Boot

systemctl enable sentinel.service

View开机Start状态

systemctl is-enabled sentinel.service

ViewService状态

systemctl status sentinel

手动Start Sentinel

systemctl start sentinel

手动停止Sentinel

systemctl stop sentinel

手动RestartSentinel

systemctl restart sentinel

6、结果

根据StartLogging

INFO: Sentinel log output type is: file
INFO: Sentinel log charset is: utf-8
INFO: Sentinel log base directory is: /root/logs/csp/
INFO: Sentinel log name use pid is: false
INFO: Sentinel log level is: INFO
