Java开发环境配置

标签：Java 配置开发 usr https mysql brew 官网下载

前言

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；
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

配置说明

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

MySQL

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

配置说明

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

#mysql
export PATH=$PATH:/usr/local/mysql/bin
export PATH=$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 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]

# Don't listen on a TCP/IP port at all. This can be a security enhancement,  
# if all processes that need to connect to mysqld run on the same host.

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

官网下载：https://redis.io/docs/getting-started/

配置说明

Jmeter

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

配置说明

下载：官网下载太慢，选择阿里云镜像下载，下载地址 https://mirrors.aliyun.com/apache/jmeter/binaries/?spm=a2c6h.25603864.0.0.436f69a5u1Mo7X
解压：sudo tar -zxvf apache-jmeter-5.5.tgz -C DevelopTools

启动配置修改：/bin/jmeter.properties

# 修改语言
language=zh_en改成language=zh_CN
# 修改编码
sampleresult.default.encoding=ISO-8859-1 改为 UTF-8

启动：sh /bin/jmeter.sh
使用（参考文章：https://www.jianshu.com/p/20fac18f478f）
- 添加线程组
- 添加Http请求
- 启动测试即可
