CentOS安装Sentinel并自启动 CentOS安装Sentinel设置自启动1、下载下载地址https://github.com/alibaba/Sentinel/releases2、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.

Jenkins容器docker部署springboot项目-问题记录 Jenkins容器docker部署springboot项目-问题记录一、docker容器内不能使用vim解决方案：以root进入容器内docker exec -it -user root jenkins /bin/bash更新软件包apt-get update升级过程可能非常慢，因为是从海外站点拉取镜像，所以我们可以配置一个国内的镜像源，加速镜像拉取更新。备份原文件mv /etc/apt/sources.list /etc/apt/sources.list.bak查看容器中Debian版本cat /etc/issue修改配置sources.list文件根据自己版本修改成对应内容，修改内容参考阿里镜像https://developer.aliyun.com/mirror/debian我容器Debian为11.x版本，修改内容为：cat >/etc/apt/sources.list <<EOF deb http://mirrors.aliyun.com/debian/ bullseye main non-free contrib deb-src http://mirrors.aliyun.com/debian/ bullseye main non-free contrib deb http://mirrors.aliyun.com/debian-security/ bullseye-security main deb-src http://mirrors.aliyun.com/debian-security/ bullseye-security main deb http://mirrors.aliyun.com/debian/ bullseye-updates main non-free contrib deb-src http://mirrors.aliyun.com/debian/ bullseye-updates main non-free contrib deb http://mirrors.aliyun.com/debian/ bullseye-backports main non-free contrib deb-src http://mirrors.aliyun.com/debian/ bullseye-backports main non-free contrib EOF重新执行apt-get update安装vimapt-get install -y vim安装rpmapt-get install rpm -y二、docker容器内vim不能粘贴内容vim右键进入visual模式无法粘贴解决方案vim /usr/share/vim/vim80/defaults.vim修改内容：第70行，在mouse=a的=前面加个-，修改后如下：if has('mouse') set mouse-=a endif三、docker容器内环境配置修改环境变量配置vi /etc/profile新增jdk、mavn环境变量配置# java环境变量 export JAVA_HOME=/jdk/jdk-11.0.10 export JRE_HOME=$JAVA_HOME/jre export PATH=$JAVA_HOME/bin:$PATH export CLASSPATH=./:JAVA_HOME/lib:$JRE_HOME/lib # maven环境变量 export M2_HOME=/maven/apache-maven-3.8.5 export PATH=$PATH:$JAVA_HOME/bin:$M2_HOME/bin重新加载环境变量source /etc/profile检验是否配置成功java -version mvn -v
