WakaTime for Terminal

• Sudo easy_install PIP = = 20.3.4
• sudo easy_install pip
• sudo pip install wakatimePlease use | if failurePIP install -- target = / Library/Python / 2.7 / site - packages wakatime
• cd ~/.oh-my-zsh/custom/plugins

vim

You are advised to use github.com/amix/vimrc

$ git clone --depth=1 https://github.com/amix/vimrc.git ~/.vim_runtime
$ sh ~/.vim_runtime/install_awesome_vimrc.sh
$ echo "set number" >> ~/.vimrc
$ echo "set showcmd" >> ~/.vimrc
$ source ~/.vimrc
Copy the code

Git

Command line tool

// Re-installing Git on Mac OSX with Brew
$ alias git='/usr/local/bin/git'
$ brew install git
Copy the code

Command Line Configuration

# 1. Initialize Settings
$ git config --global user.name 'youngjuning'
$ git config --global user.email '[email protected]'
# 2. Setting 'color. UI' to 'auto' makes the output of the command more readable.
$ git config --global color.ui auto
Git remembers the username and password
$ git config --global credential.helper store
# 4, the core autocrlf
$ git config --global core.autocrlf input
# 5. Output to Terminal instead of vim
$ git config --global pager.branch false
Copy the code

Linux or Mac systems use LF as the line terminator, so you don’t want Git to automatically convert files when checking them out; For example, if a file ends at the end of a line (CRLF) then you might want to modify it by changing core. Trigger LF to input and then forcing Git to change CRLF to LF at commit and end at checkout: This preserves CRLF in checkout files on Windows systems, and IT preserves LF on Mac and Linux systems, including repositories.

Node

Node.js is a JavaScript runtime based on the Chrome V8 engine. We use the n module to maintain the version of Node:

$ brew install n
#Install the latest version
$ sudo n latest
## Other commands ##
#Install the specified version
$Sudo n 10.16.0
#Install the latest stable version
$ sudo n lts
#Delete the specified version
$N the rm 12.10.0
#All cached versions except the current version
$ n prune
Copy the code

Update the NPM

$ sudo npm install -g npm
Copy the code

NRM management registry

$ sudo i -g nrm
#Lists the available agents
$ nrm ls
#Adding a Private Proxy
$ nrm add local http://127.0.0.0:4873 http://127.0.0.0:4873
Copy the code

d8

Do not use Brew Install V8, available commands are incomplete

Preparation conditions

• Install Xcode (Avaliable on the Mac App Store)
• Install Xcode Command Line Tools (Preferences > Downloads)
• Install depot_tools
  • cd ~ && git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
  • sudo nano ~/.zshrc(zsh) or sudo nano ~/.bash_profile(bash)
  • Add export PATH=~/depot_tools:"$PATH" (it’s important that depot_tools comes first here)
  • source ~/.zshrc
  • From the directory you want to install V8 into, run gclient

Build V8

• fetch v8
• cd ~/v8
• gclient sync
• tools/dev/v8gen.py x64.optdebug
• ninja -C out.gn/x64.optdebug (prepare for lots of fan noise)

I’d also recommend adding these to your .zshrc:

• sudo nano ~/.zshrc
• Add alias d8=~/v8/out.gn/x64.optdebug/d8
• Add alias tick-processor=~/v8/tools/mac-tick-processor
• Add export D8_PATH="~/v8/out.gn/x64.optdebug"
• source ~/.zshrc

For details about how to use Demo, see D8-shell-examples

Java

Download and install

• javase-jdk8-downloads
• The Oracle Java archive

Practical command

• Check the JDK version and installation directory /usr/libexec/java_home -v in Mac

  Matching Java Virtual Machines (2):
   1.8.0_221, x86_64:	"Java SE 8"/ Library/Java/JavaVirtualMachines jdk1.8.0 _221. JDK/Contents/Home 1.7.0 _80, x86_64:"Java SE 7"/ Library/Java/JavaVirtualMachines jdk1.7.0 _80. JDK/Contents/Home / Library/Java/JavaVirtualMachines jdk1.8.0 _221. JDK/Contents/HomeCopy the code

• Check the JRE version: Java-version

• Check the JDK version: javac-version

Maven

The installation

$ brew install maven
Copy the code

Configure the Maven local repository

The setting. XML path is ${Maven Home}/conf/settings. XML. Maven Home can be obtained from MVN –version

<localRepository>~/maven_repo</localRepository>
Copy the code

You can copy settings. XML directly to the.m2 folder for configuration.

If there is no.m2 folder, run the command

$ mvn help:system
Copy the code

Then open the current user’s directory, where you can find the.m2 folder

Configuring Ali Mirror

<mirror>
  <id>alimaven</id>
  <name>aliyun maven</name>
  <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
  <mirrorOf>central</mirrorOf>
</mirror>
Copy the code

To upgrade the Maven

$ brew unlink
$ brew update
$ brew install maven
Copy the code

MySql

$ brew install mysql
Copy the code

Modifying a Configuration File

$ nano /usr/local/etc/my.cnf
Copy the code

Start the service

brew services start mysql
#restart
brew services restart mysql
#stop
brew services stop mysql
Copy the code

Or, if you don’t want/need a background service you can just run: mysql.server start

Security Settings

$ mysql_secure_installation
Copy the code

1. Set up a password authentication plug-in

   Securing the MySQL server deployment.
   
   Connecting to MySQL using a blank password.
   
   VALIDATE PASSWORD PLUGIN can be used to test passwords and improve security. It checks the strength of password and allows the users to set only those passwords which are secure enough. Would you like to setup VALIDATE PASSWORD plugin?
   
   Press y|Y for Yes, any other key for No: y
   Copy the code

2. Select password Rules

   There are three levels of password validation policy:
   
   LOW    Length >= 8
   #The length is greater than or equal to 8
   MEDIUM Length >= 8, numeric, mixed case, and special characters
   #The value contains at least 8 digits, uppercase and lowercase letters, and special characters
   STRONG Length >= 8, numeric, mixed case, special characters and dictionary                  file
   #8 or more in length, numbers, upper and lower case letters, special symbols, and dictionary files (carefully selected!)Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 1 Please set the password for root here. New password: Re-enter new password: (Enter your password again)Copy the code

3. Create a new password that meets the rules

   Estimated strength of the password: 50 # Do you wish to continue with the password provided? (Press y|Y for Yes, any other key for No) : yCopy the code

4. Deleting an Anonymous User

   By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother.
   You should remove them before moving into a production environment.
   
   Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
   Success.
   Copy the code

5. Disabling remote Login

   Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network.
   
   Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
   Success.
   Copy the code

6. Delete the test data table

   By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment.
   
   Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
    - Dropping test database...
   Success.
   
    - Removing privileges on test database...
   Success.
   Copy the code

7. Done

   Reloading the privilege tables will ensure that all changes made so far will take effect immediately.
   
   Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
   #Whether to reload the permission table
   Success.
   
   All done!
   Copy the code

Your password does not satisfy the current policy requirements.

If you choose a password rule by mistake, you choose 2, which is a combination of numbers, upper and lower case letters, special symbols, and dictionary files. You’ll notice that mysql_secure_installation won’t give you a chance to reset. Manual smile, MMP. There are ways:

SHOW VARIABLES LIKE 'validate_password%';
Copy the code

Run the mysql -u root command to log in to the database.

set global validate_password.policy=0;
set global validate_password.length=4;
#Set the password rule to LOW to use alphanumeric passwords
Copy the code

landing

$ mysql -u root -p
Copy the code
