1.安装brew
Homebrew是以最简单，最灵活的方式来安装苹果公司在MacOS中不包含的UNIX工具
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
如遇
Press RETURN to continue or any other key to abort
==> Downloading and installing Homebrew...
error: could not lock config file /usr/local/Homebrew/.git/config: Permission denied
fatal: could not set 'core.repositoryformatversion' to '0'
Failed during: git init -q
权限不够，则
sudo chgrp -R admin /usr/local
sudo chmod -R g+w /usr/local
改变目录权限
brew update 更新brew
brew install {应用名，如git} 安装软件
brew cask install {应用名，如git} 也是下载安装，与上面的区别，请查看https://www.zhihu.com/question/22624898
更多用法请 brew help
如安装下载node brew install node
如遇 Warning: node 12.4.0 is already installed and up-to-date
To reinstall 12.4.0, run `brew reinstall node`
则 brew upgrade node
2.安装jdk，安装完毕 java -version
3.安装maven，brew install maven 安装完毕 mvn -version
查找Java_home路径的命令/usr/libexec/java_home
objc[6704]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_101.jdk/Contents/Home/bin/java (0x1026804c0) and /Library/Java/JavaVirtualMachines/jdk1.8.0_101.jdk/Contents/Home/jre/lib/libinstrument.dylib (0x1027044e0). One of the two will be used. Which one is undefined.
解决办法：
help-Edit Custom Properties 里添加
# custom IntelliJ IDEA properties
idea_rt
idea.no.launcher=true
4.Chrome浏览器jsonview插件安装
https://www.cnblogs.com/whycxb/p/7126116.html
Chrome浏览器安装Set Character Encoding
https://jingyan.baidu.com/article/5552ef47974e5f518ffbc9f8.html
5.UrlEncode编码/UrlDecode解码 - 站长工具
http://tool.chinaz.com/tools/urlencode.aspx
6.iterm2下字体以及配色方案，Mac下终端配置（iterm2 + oh-my-zsh + solarized配色方案）
idea下不显示git分支，要安装 oh-my-zsh 即可
http://www.cnblogs.com/weixuqin/p/7029177.html
修改完iterm主题，记得source！！！若选择agnoster主题，应用这个主题需要特殊的字体支持，否则会出现乱码情况
进入：iTerm2 > Profiles > Text > Font，修改字体为：Meslo LG S DZ Regular for Powerline
个人选择的是"robbyrussell"主题，当然也有选ys主题的，看个人爱好吧
7.解决iterm2不支持rz sz
https://www.cnblogs.com/zhaoyawei/p/9121161.html
8.cdto安装，建议先安装iterm2，配合使用
https://blog.csdn.net/kissdge/article/details/50147409
https://github.com/jbtule/cdto/releases
9.github用户名lishan-bat
10.pycharm注册码
11.Intellij IDEA导入JAVA项目
https://blog.csdn.net/wd2014610/article/details/79637935
12.解决IntelliJ IDEA CE乱码的问题
https://www.jb51.net/article/135816.htm
Preference- Editor- FileEncodings
修改Global Encoding、Project Encoding、Default encoding for properties files都为UTF-8
13. json格式在线解析
14. 配置lombok
https://www.projectlombok.org/
15. 关于.gitignore
git规则
.gitignore只能忽略那些原来没有被track的文件，如果某些文件已经被纳入了版本管理中，则修改.gitignore是无效的
如果在个人目录下，添加了.gitignore，则提交代码时优先匹配 ~/.gitignore_global 的规则，其次是项目根目录或者.git文件夹下的.gitignore规则
解决办法
在个人目录下vim ~/.gitignore_global 添加如下配置
# Compiled class file
*.class
*.o
*.so
*.dll
*.exe
*.pid
# Log file
logs/
*.log
# Package Files
*.jar
*.war
*.ear
*.sar
*.tar
*.tar.gz
*.zip
*.rar
*.7z
*.iso
*.dmg
*.rpm
# Eclipse project files
.classpath
.project
.settings/
# Intellij project files
*.iml
.idea/

# Avoid ignoring Gradle wrapper jar file (.jar files are usually ignored)
!gradle-wrapper.jar
## maven
target/
pom.xml.tag
pom.xml.releaseBackup
pom.xml.versionsBackup
pom.xml.next
release.properties
dependency-reduced-pom.xml
buildNumber.properties
.mvn/timing.properties
# Avoid ignoring Maven wrapper jar file (.jar files are usually ignored)
!/.mvn/wrapper/maven-wrapper.jar
git rm -r --cached .
git add .
git commit -m 'update .gitignore'.gitignore文件 具体的规则一搜就有。我在使用GIT的过程中，明明写好了规则，但问题不起作用，每次还是重复提交，无法忍受。其实这个文件里的规则对已经追踪的文件是没有效果的。所以我们需要使用rm命令清除一下相关的缓存内容。这样文件将以未追踪的形式出现 然后再重新添加提交一下 .gitignore文件里的规则就可以起作用了

16. Navicat安装--之前有付费版，上传到百度云了，这个公司不可以访问百度云呵呵
下载参考博客 https://www.jianshu.com/p/f3ef78deadaa
破解参考博客 https://blog.csdn.net/xhd731568849/article/details/79751188
17. macOS系统半身支持yum，如果服务器如常见的centOS没有yum，则参考博客
https://www.cnblogs.com/xuliangxing/p/7132656.html?utm_source=itdadao&utm_medium=referral
最简单安装 Ruby 的方式是使用 yum 或 apt-get。在命令提示符中输入以下的命令，即可在您的计算机上安装 Ruby。
$ sudo yum install ruby # CentOS, Fedora, 或 RHEL 系统
sudo apt-get install ruby-full # Debian 或 Ubuntu 系统
如果你是苹果系统，可以使用 brew 命令安装：
$ brew install ruby # macOS系统

需要注意的是，貌似直接复制粘贴激活码就行，如果修改文件 放jar包会导致文件移至废弃篓打不开破损

19. 除了processon好用的画图软件推荐谷歌插件 Gliffy Diagrams
由于谷歌商店下架了此插件
下载：https://blog.csdn.net/u010402584/article/details/81207430
安装：http://www.cnplugins.com/tool/outline-install-crx-file.html
离线安装2019变化了需要把bhmicilclplefnflapjmnngmkkkkpfad-1.0.31-Crx4Chrome.com.crx 重命名为 bhmicilclplefnflapjmnngmkkkkpfad-1.0.31-Crx4Chrome.com.zip 再用命令行unzip bhmicilclplefnflapjmnngmkkkkpfad-1.0.31-Crx4Chrome.com.zip 从谷歌浏览器-更多设置-扩展程序安装解压缩包
20.Mac系统如何显示隐藏文件
在终端中输代码“defaults write com.apple.finder AppleShowAllFiles -boolean true;killall Finder”即可显示隐藏文件
再次隐藏文件，可以输入命令“defaults write com.apple.finder AppleShowAllFiles -boolean false;killall Finder”。
