zookeeper

zookeeper安装配置

• 从官网下载zookeeper的安装包:官网推荐的zookeeper镜像下载网站
• 将zookeeper的压缩包解压到指定安装目录
• 在zookeeper安装目录新建 data 和 log 文件夹,将conf目录下的 zoo_sample.cfg 文件，复制一份，重命名为 zoo.cfg ,在zoo.cfg 中配置tickTime, dataDir, dataLogDir.

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
#initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
#syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=E:\JetBrains\zookeeper-3.4.10\data
dataLogDir=E:\JetBrains\zookeeper-3.4.10\log
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

注:各个配置属性说明

tickTime：这个时间是作为 Zookeeper 服务器之间或客户端与服务器之间维持心跳的时间间隔，也就是每个 tickTime 时间就会发送一个心跳。
initLimit：这个配置项是用来配置 Zookeeper 接受客户端（这里所说的客户端不是用户连接 Zookeeper 服务器的客户端，而是 Zookeeper 服务器集群中连接到 Leader 的 Follower 服务器）初始化连接时最长能忍受多少个心跳时间间隔数。当已经超过 10 个心跳的时间（也就是 tickTime）长度后 Zookeeper 服务器还没有收到客户端的返回信息，那么表明这个客户端连接失败。总的时间长度就是 5*2000=10 秒
syncLimit：这个配置项标识 Leader 与 Follower 之间发送消息，请求和应答时间长度，最长不能超过多少个 tickTime 的时间长度，总的时间长度就是 2*2000=4 秒
dataDir：顾名思义就是 Zookeeper 保存数据的目录，默认情况下，Zookeeper 将写数据的日志文件也保存在这个目录里。
clientPort：这个端口就是客户端连接 Zookeeper 服务器的端口，Zookeeper 会监听这个端口，接受客户端的访问请求。

• 配置环境变量

1.添加系统变量 ZOOKEEPER_HOME:E:\JetBrains\zookeeper-3.4.10
2.新建在Path变量 Path:%ZOOKEEPER_HOME%/bin;%ZOOKEEPER_HOME%/conf
1
2

• 点击 E:\JetBrains\zookeeper-3.4.10\bin目录下的 zkServer.cmd运行zookeeper即可运行成功.

zookeeper运行问题

• 在我的工作电脑上,使用的zookeeper中配置了windows批处理工具,只需要点击RUN即可完成所有配置并运行:
• 以后需要学习一下windows批处理工具

node.js(npm)

node.js(npm)安装配置

• 从官网下载node.js的安装包:node.js官网下载
• 双击安装包,开始安装node.js
• node.js安装结束后,打开cmd窗口,输入node -v,npm -v测试node.js是否安装成功

C:\Users\Chova>node -v
C:\Users\Chova>npm -v
1
2

• node.js中npm的配置:在node.js安装目录下创建node_cache和node_global文件夹，设置为全局安装位置和缓存位置.打开cmd命令窗口，输入

npm config set prefix  E:\JetBrains\nodejs\node_global  
npm config set cache E:\JetBrains\nodejs\node_cache
1
2

• 配置node.js的环境变量

1.在 系统变量 下新建 NODE_PATH ,输入E:\JetBrains\nodej\node_global\node_modules
2.将 用户变量 下的 Path 修改为 E:\JetBrains\nodej\node_global

node.js(npm)运行问题

• 在使用

npm start
1

问题一:运行node.js项目时,出现以下报错

A complete log of this run can be found in:
C:\Users\56386\AppData\Roaming\npm-cache\_logs\2019-04-26T02_09_33_735Z-debug.log

• 解决办法:

npm i npm -g	全局更新

或者

npm cache clean --force		清理后重新安装

或者

npm install webpack --save		强制安装依赖

问题二:运行有webpack提示,缺少webpack插件

• 解决办法:

npm install webpack@3.6.0 -g

npm i optimize-css-assets-webpack-plugin@3.2.0

如果解决成功后,在package.json中的dependencies中会有"webpack": “^3.6.0”,如果还是没有相关依赖,则最终执行

npm install webpack --save		# 强制安装依赖

redis

redis安装配置

• 从GitHub上下载3.2版本的redis安装包:redis
• 安装完成后,默认已经开启redis服务.也可以在cmd窗口输入启动命令

C:\Users\Chova>redis-server.exe
1

因为默认开启的redis服务已经使用了6379,使用cmd窗口启动redis时需要关闭windows服务中的redis服务.

• redis中各个文件介绍

redis-server.exe：服务端程序，提供redis服务
redis-cli.exe: 客户端程序，通过它连接redis服务并进行操作
redis-check-dump.exe：本地数据库检查
redis-check-aof.exe：更新日志检查
redis-benchmark.exe：性能测试，用以模拟同时由N个客户端发送M个 SETs/GETs 查询 (类似于 Apache 的ab 工具).
redis.windows.conf: 配置文件，将redis作为普通软件使用的配置，命令行关闭则redis关闭
redis.windows-service.conf：配置文件，将redis作为系统服务的配置，用以区别开两种不同的使用方式

redis运行问题

• 如果redis是压缩包安装的,启动命令需要输入:

redis-server.exe redis.windows.conf

• 通过

redis-server.exe redis.windows.conf

mongodb

mongodb安装配置

• 从官网下载mongdb安装包:mongodb官网,下载windows64位:win64-mongodbb
• 双击mongodb安装包,安装到指定目录
• 配置mongodb环境变量
  
• mongodb简单使用介绍

mongo   使用数据库
mongod  开机
mongoimport  导入数据

开机命令:(开机完成后,这个cmd窗口就保持这样)
mongod --dpath c:\mongo

新开一个cmd窗口输入:
mongo

运行数据库语法:
show dbs	列出所有数据库
use dbname	使用数据库
db			查看当前所在数据库
db.dbname.insert({});	插入数据
db.dropDatabase();		删除数据库，删除当前所在的数据库

db.restaurants.find();	查找数据，用find。find中没有参数，那么将列出这个集合的所有文档
db.dbname.find({"score.shuxue":70});	精确匹配
db.dbname.find({"score.shuxue":70 , "age":12});		多个条件
db.dbname.find({"score.yuwen":{$gt:50}});			大于条件	
db.dbname.find({$or:[{"age":9},{"age":11}]});		寻找所有年龄是9岁，或者11岁的
db.dbname.find().sort({ "borough": 1, "address.zipcode": 1 })	查找完毕之后，打点调用sort，表示升降排序

db.dbname.update({"name":"小明"},{$set:{"age":16}});			查找名字叫做小明的，把年龄更改为16岁
db.dbname.update({"score.shuxue":70},{$set:{"age":33}});		查找数学成绩是70，把年龄更改为33岁
db.dbname.update({"sex":"男"},{$set:{"age":33}},{multi: true});	更改所有匹配项目
db.restaurants.remove( { "borough": "Manhattan" } );			删除数据

 |
 |  2. Global Level. This settings.xml file provides configuration for all Maven
 |                 users on a machine (assuming they're all using the same Maven
 |                 installation). It's normally provided in

   | it to several places.
   |
   | That repository definition will have a unique id, so we can create a mirror reference for that

  <!-- profiles
   | This is a list of profiles which can be activated in a variety of ways, and which can modify
   | the build process. Profiles provided in the settings.xml are intended to provide local machine-
   | specific paths and repository locations which allow the build to work in the local environment.
   |
   | For example, if you have an integration testing plugin - like cactus - that needs to know where
   | your Tomcat instance is installed, you can provide a variable here such that the variable is
   | dereferenced during the build process to configure the cactus plugin.
   |
   | As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles
   | section of this document (settings.xml) - will be discussed later. Another way essentially
   | relies on the detection of a system property, either matching a particular value for the property,
   | or merely testing its existence. Profiles can also be activated by JDK version prefix, where a
   | value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'.
   | Finally, the list of active profiles can be specified directly from the command line.
   |
   | NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact
   |       repositories, plugin repositories, and free-form properties to be used as configuration
   |       variables for plugins in the POM.
   |
   |-->
  <profiles>
  
  
    <!-- profile
     | Specifies a set of introductions to the build process, to be activated using one or more of the
     | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/>
     | or the command line, profiles have to have an ID that is unique.
     |
     | An encouraged best practice for profile identification is to use a consistent naming convention
     | for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc.
     | This will make it more intuitive to understand what the set of introduced profiles is attempting
     | to accomplish, particularly when you only have a list of profile id's for debug.
     |
     | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.
    <profile>
      <id>jdk-1.4</id>

      <activation>
        <jdk>1.4</jdk>
      </activation>

      <repositories>
        <repository>
          <id>jdk14</id>
          <name>Repository for JDK 1.4 builds</name>
          <url>http://www.myhost.com/maven/jdk14</url>
          <layout>default</layout>
          <snapshotPolicy>always</snapshotPolicy>
        </repository>
      </repositories>
    </profile>
    -->

    <!--
     | Here is another profile, activated by the system property 'target-env' with a value of 'dev',
     | which provides a specific path to the Tomcat instance. To use this, your plugin configuration
     | might hypothetically look like:
     |
     | ...
     | <plugin>
     |   <groupId>org.myco.myplugins</groupId>
     |   <artifactId>myplugin</artifactId>
     |
     |   <configuration>
     |     <tomcatLocation>${tomcatPath}</tomcatLocation>
     |   </configuration>
     | </plugin>
     | ...
     |
     | NOTE: If you just wanted to inject this configuration whenever someone set 'target-env' to
     |       anything, you could just leave off the <value/> inside the activation-property.
     |
    <profile>
      <id>env-dev</id>

      <activation>
        <property>
          <name>target-env</name>
