Java开发环境配置 - 晚秋的风

1. 本文主要以OS为Mac Apple芯片版本为主进行记录，其他OS均可在提供的官网链接中找到相应的配置说明；
2. 本文暂时记录了Homebrew、JDK8、Maven3.9.0、MySQL8.0、Redis、Jmeter这些程序的环境配置，其他程序待后续使用时再补充。

Homebrew

官网下载地址：https://brew.sh/index_zh-cn

• 下载步骤
  1. 打开终端》输入
     /bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"
  2. 选择镜像，如中科院
  3. 等待下载完成，如果提示需要安装git，则先安装git，再执行shell安装脚本
  4. 安装完成后，“brew -v”查看版本
  5. 安装目录/opt/homebrew
  6. 卸载
     /bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/HomebrewUninstall.sh)"

官网下载地址：https://www.oracle.com/java/technologies/javase/javase8-archive-downloads.html

• windows：https://www.runoob.com/java/java-environment-setup.html

• • 官网下载：下载“JDK-8U202-macOSX-X64.dmg”或其他macOS版本，一步步点击即可【X64和Apple芯片均兼容】
  • 安装路径：/Library/Java/JavaVirtualMachines/jdk1.8.0_351.jdk/Contents/Home
  • 环境变量配置：/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java
  • 完全卸载：
    • 删除jdk
      sudo rm -rf /Library/Java/JavaVirtualMachines/jdk1.8.0_351.jdk
    • 删除运行路径和环境
      sudo rm -rf /Library/Internet\ Plug-Ins/JavaAppletPlugin.pluginsudo rm -rf /Library/PreferencesPanes/JavaControlPanel.prefPanesudo rm -rf /Library/Application\ Support/Java

• linux

  • 官网下载：下载"jdk-8u202-linux-x64.tar.gz"或者其他linux版本
  • 解压：tar -zxvf jdk-8u202-linux-x64.tar.gz -C /usr/local
  • 配置环境变量
    # 环境变量配置存放在/etc/profile，改变前先复制一份备用cp /etc/profile /etc/profile-init# 打开编辑文件vim /etc/profile# 在最前面或最后面添加JDK环境变量export JAVA_HOME=/download/jdk1.8.0_202export PATH=$JAVA_HOME/bin:$PATHexport CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

Maven

• 配置参考：https://www.runoob.com/maven/maven-setup.html【菜鸟教程】
• setting.xml文件配置：https://maven.apache.org/settings.html【官网说明】
• 自用setting.xml
  <?xml version="1.0" encoding="UTF-8"?><settings xmlns="http://maven.apache.org/SETTINGS/1.2.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.2.0 https://maven.apache.org/xsd/settings-1.2.0.xsd"> <!-- 本地仓库 --> <localRepository>/Users/mybook/DevelopTools/apache-maven-3.9.0/Repository</localRepository> <pluginGroups></pluginGroups> <proxies></proxies> <!--私服用户配置，没用私服不需要配置了--> <servers></servers> <!--镜像中央仓库--> <mirrors> <mirror> <id>alimaven</id> <name>aliyun maven</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <mirrorOf>central</mirrorOf> </mirror> <mirror> <id>central</id> <name>Maven Repository Switchboard</name> <url>https://repo1.maven.org/maven2/</url> <mirrorOf>central</mirrorOf> </mirror> <mirror> <id>jboss-public-repository-group</id> <mirrorOf>central</mirrorOf> <name>JBoss Public Repository Group</name> <url>http://repository.jboss.org/nexus/content/groups/public</url> </mirror> </mirrors> <!--私服用户配置，没用私服不需要配置了--> <profiles></profiles> <activeProfiles></activeProfiles></settings>

MySQL

官网下载地址：https://dev.mysql.com/downloads/mysql/

• mac

  • 下载：直接下载"macOS 13 (ARM, 64-bit), DMG Archive "，一路点击，密码选择"use legacy password encryption"，设置root用户的登录密码

  • 配置环境变量

    # 编辑，设置如下内容sudo vim /etc/profile# 配置生效source /etc/profile# 查看版本mysql --version
    #mysqlexport PATH=$PATH:/usr/local/mysql/binexport PATH=$PATH:/usr/local/mysql/support-files

  • 启动、安装/卸载、配置

    
• linux
  • 下载：https://dev.mysql.com/downloads/mysql/
  • 解压：tar -xvJf mysql-8.0.21-linux-glibc2.12-x86_64.tar.xz
  • 重命名：mv mysql-8.0.21-linux-glibc2.12-x86_64 mysql8.0
  • 创建数据存储目录：mkdir /../mysql8.0/data
  • 创建mysql用户和用户组，并设置权限
    # 创建mysql用户和用户组groupadd mysqluseradd -g mysql mysql# 给mysql用户赋予权限chown -R mysql.mysql /usr/local/mysql/
  • 初始化mysql信息
    cd /usr/local/mysql/bin# 初始化基本信息./mysqld --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/ --initialize# 获取临时密码：最后一行 root@localhost: lxkqDibw2?Yn
  • 添加mysql服务到系统
    cd /usr/local/mysql/mysql8.0# 将mysqld服务添加到系统cp -a ./support-files/mysql.server /etc/init.d/mysql# 授权以及添加服务chmod +x /etc/init.d/mysqlchkconfig --add mysql# 创建my.cnf文件sudo vim /etc/my.cnf# 设置权限sudo chmod 664 /etc/my.cnf
    # Example MySQL config file for small systems. # # This is for a system with little memory (<= 64M) where MySQL is only used # from time to time and it's important that the mysqld daemon # doesn't use much resources. # # MySQL programs look for option files in a set of # locations which depend on the deployment platform. # You can copy this option file to one of those # locations. For information about these locations, see: # http://dev.mysql.com/doc/mysql/en/option-files.html # # In this file, you can use all long options that a program supports. # If you want to know which options a program supports, run the program # with the "--help" option. # The following options will be passed to all MySQL clients [client] default-character-set=utf8 #password = k0Ui&wV(Z3ytport = 3306 socket = /tmp/mysql.sock # Here follows entries for some specific programs # The MySQL server [mysqld] #配置mysql的文件夹 和 mysql data目录basedir=/usr/local/mysql/mysql8.0datadir=/usr/local/mysql/mysql8.0/datadefault-storage-engine=INNODB character-set-server=utf8 collation-server=utf8_general_ci port = 3306 socket = /tmp/mysql.sock skip-external-locking key_buffer_size = 16K max_allowed_packet = 1M table_open_cache = 4 sort_buffer_size = 64K read_buffer_size = 256K read_rnd_buffer_size = 256K net_buffer_length = 2K thread_stack = 128K # Don't listen on a TCP/IP port at all.

服务启动/关闭/登录/退出

• mysql服务启动/关闭
  # 启动mysql服务service mysql start# 查看mysql运行状态service mysql status# 将mysql命令添加到服务ln -s /usr/local/mysql/mysql8.0/bin/mysql /usr/bin# 关闭mysql服务service mysql stop
• mysql服务登录/退出
  # 登录mysql mysql -uroot -p# 退出quit;# 修改root密码 mysql>ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';# 刷新缓存flush privileges;

推荐两款使用下来体验很不错的客户端： Navicat（收费，或找破解版）、DBeaver（开源免费，但下载程序后还需要下载驱动才可使用）

Redis

Jmeter

官网下载地址：https://jmeter.apache.org/download_jmeter.cgi
