CentOS安装Sentinel设置自启动
1、下载
下载地址https://github.com/alibaba/Sentinel/releases
2、安装
提前创建好安装路径、Jar包存放文件夹、脚本执行文件夹、日志存放文件夹
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.jar执行Jar包上传至jar文件夹
3、脚本
编写脚本sentinel.sh，按照自己路径、版本号调整，存放到上面新建的sh文件夹中。脚本如下：
#!/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/文件夹下，执行命令修改权限
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，导致启动失败，可使用notepad++中编辑-->文档格式转换-->转换成Unix格式。
2、注意给脚本设置权限
4、测试
本地测试是否能够启动
启动sentinel服务
sh sentinel.sh start停止sentinel服务
sh sentinel.sh stop重启sentinel服务
sh sentinel.sh restart查看sentinel服务状态
sh sentinel.sh status服务启动后，可通过IP+端口+项目名访问Sentinel登录页面
5、自启动
本地测试可通过命令启动没问题后，编写启动服务sentinel.service，放到/usr/lib/systemd/system目录，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重载所有服务
systemctl daemon-reload设置开机启动
systemctl enable sentinel.service查看开机启动状态
systemctl is-enabled sentinel.service查看服务状态
systemctl status sentinel手动启动 Sentinel
systemctl start sentinel手动停止Sentinel
systemctl stop sentinel手动重启Sentinel
systemctl restart sentinel6、结果
根据启动日志
