Java开发环境配置

前言

  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

配置说明

  • 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

      Java开发环境配置

  • 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 mysql useradd -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/mysql chkconfig --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(Z3yt port        = 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/mysql8.0 datadir=/usr/local/mysql/mysql8.0/data default-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; 

客户端

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
