netstat 命令参数和使用详解
netstat - Print network connections, routing tables, interface statistics, masquerade connections, and multicast memberships
netstat - 打印网络连接、路由表、接口统计、伪装连接和多播成员关系
- -a 显示所有状态的 socket
- -n 不做名字解析,不加此参数,80 端口会显示成 http,127.0.0.1 显示成 localhost,uid 为 0 显示成 root 等等
- -e 显示更多信息如用户,inode
- -p 显示 pid 和程序名字
- -t 显示 tcp 链接
- -u 显示 udp 链接
- -x 显示 unix 套接字
netstat -anpte #查看 tcp 链接
netstat -anpue #查看 udp 链接
netstat -anpxe #查看 unix 套接字链接
netstat -r # 查看路由表 netstat -r 和 route 命令输出是差不多的
netstat -s # 查看网络统计数据,netstat -s 展示各协议的统计信息
netstat -i # 查看网络接口信息
netstat -rF 和 netstat -rC 两个命令的区别是一个输出的是路由表,一个输出的是路由缓存。
默认 netstat -r 输出的是 netstat -rF 结果。-F 为默认参数

- mvn install
- mvn spring-boot:build-image or gradle bootBuildImage
- Spring Native 0.9.2 设计用于 Spring Boot 2.4.5。为了保证支持和兼容性,最新的 Spring Boot 2.x 次要版本的每个修补版本都会发布一个新版本的 Spring Native。
- Spring Native 0.9.2 仅支持 Spring Boot 2.4.5,建议使用指定版本。

- UNIX Socket 是同一台服务器上不一样进程间的通讯机制。
- TCP/IP Socket 是网络上不一样服务器之间进程的通讯机制,也可让同一服务器的不一样进程通讯。服务器
- Postgres 的一位核心开发者曾经作过实验,证实 UNIX Socket 的方式比 TCP/IP Socket 方式要快 31%,
- 因此,在同一个服务器上应该优先选择 UNIX Socket 方式。网络
- influxDB-数据保存策略
- retention policy: 存储策略,用于设置数据保留的时间,每个数据库刚开始会自动创建一个默认的存储策略 autogen,
- 数据保留时间为永久,之后用户可以自己设置,例如保留最近 2 小时的数据。
- 插入和查询数据时如果不指定存储策略,则使用默认存储策略,且默认存储策略可以修改。InfluxDB 会定期清除过期的数据。

- 依次执行:
- 登录 master
- ssh-keygen -t rsa

- 2.master 可当作 Node 使用
- kubectl taint node master node-role.kubernetes.io/master#将 Master 也当作 Node 使用
- kubectl taint node master node-role.kubernetes.io/master="":NoSchedule #将 Master 恢复成 Master Only 状态

- 1、docker 三个基本概念:
- • 镜像(Image):Docker 镜像(Image),就相当于是一个 root 文件系统。比如官方镜像 ubuntu:16.04 就包含了完整的一套 Ubuntu16.04 最小系统的 root 文件系统。
- • 容器(Container):镜像(Image)和容器(Container)的关系,就像是面向对象程序设计中的类和实例一样,镜像是静态的定义,容器是镜像运行时的实体。容器可以被创建、启动、停止、删除、暂停等。
- • 仓库(Repository):仓库可看着一个代码控制中心,用来保存镜像。
- 2、docker 的镜像分层
- 一个完整的 Docker 镜像可以支撑一个 Docker 容器的运行,在 Docker 容器运行过程中主要提供文件系统数据支撑。
- Docker 镜像作为 docker 中最基本的概念,有以下几个特性:
- 镜像分层,每个镜像都由一个或多个镜像层组成;
- 可通过在某个镜像加上一定的镜像层得到新镜像(此过程可通过编写 dockerfile 或基于容器 Commit 实现);
- 每个镜像层拥有唯一镜像 ID;
- 镜像在存储和使用时共享相同的镜像层(根据 ID),所以在 pull 镜像时,已有的镜像层会自动跳过下载;
- 每个镜像层都是只读,即使启动成容器,也无法对其真正的修改,修改只会作用于最上层的容器层;
- 6、附 docker 基本命令
- docker build -t friendlyhello . # Create image using this directory's Dockerfile
- docker run -p 4000:80 friendlyhello # Run "friendlyhello" mapping port 4000 to 80
- docker run -d -p 4000:80 friendlyhello # Same thing, but in detached mode
- docker container ls # List all running containers
- docker container ls -a # List all containers, even those not running
- docker container stop
# Gracefully stop the specified container - docker container kill
# Force shutdown of the specified container - docker container rm
# Remove specified container from this machine - docker container rm $(docker container ls -a -q) # Remove all containers
- docker image ls -a # List all images on this machine
- docker image rm
# Remove specified image from this machine - docker image rm $(docker image ls -a -q) # Remove all images from this machine
- docker login # Log in this CLI session using your Docker credentials
- docker tag
username/repository:tag # Tag for upload to registry - docker push username/repository:tag # Upload tagged image to registry
- docker run username/repository:tag # Run image from a registry
- $ sudo docker run hello-world
- sudo docker run hello-world
- 5.2.以非 root 用户管理 docker
- Docker 守护程序绑定到 Unix socket 而不是 TCP 端口。
- 默认情况下,Unix socke 是 root 用户才有,而其他用户只能通过使用 sudo 使用它。Docker 守护程序始终以 root 用户身份运行。
- 如果您不想在 docker 命令前加上 sudo,请创建一个名为 docker 的 Unix 组并向其添加用户。
- 当 Docker 守护程序启动时,它会创建一个可由该 docker 组成员访问的 Unix socket。
- 1.创建docker组
- sudo groupadd docker
- 2.添加user到docker组
- sudo usermod -aG docker $USER
- 请将$USER 替换为系统中你的除 root 外的某个用户。
- 3.注销并重新登录,以便重新评估您的组成员身份。

- gradlew 常用命令
- 在开发时有些小伙伴喜欢使用./gradlew 命令行进行打包编译 App,使用起来很安逸.
- ./gradlew -v //查看 Gradle、Groovy、Ant、JVM 等的版本,截图如下:
- ./gradlew clean //和 clean project 类似,截图如下:
- ./gradlew tasks --all //查看所有任务,截图如下:
- ./gradlew build --info //编译并打印日志,截图如下:
- ./gradlew clean build --refresh-dependencies //强制更新最新依赖,清除并构建,截图如下:
- ./gradlew build --info --debug --stacktrace //调试模式并打印堆栈信息 ,截图如下:
- ./gradlew installDebug //打 debug 包并安装,截图如下
- ./gradlew assembleDebug //编译并打 Debug 包
- ./gradlew assembleRelease //编译打 release 包,截图如下:
- ./gradlew installRelease //Release 模式打包并安装,截图如下
- ./gradlew uninstallRelease //卸载 Release 模式包
- ./gradlew install[productFlavorsName] app:assembleDebug //结合 productFlavorsName
- ./gradlew assembleTestRelease //Release 模式测试渠道打包
- ./gradlew dependencies //依赖信息查看
- ./gradlew dependencies --info // 查看详细的依赖信息
- ./gradlew compileDebug --stacktrace // 查看详细的资源文件信息
- 使用 gradlew 命令行还有一个好处就是,当依赖很多第三方库导致的 aapt 报错,而你又不知道具体是哪个库,可以用./gradlew build --info --debug --stacktrace 命令打印并排查对栈信息,不需要我们去手动排查,下一篇写一下排查步骤.
