Mac 安装Homebrew+git+java+node+mys

之前电脑乱七八糟装了很多东西，强迫症表示有点受不了，最近跳槽顺便把Mac重装了（已备份文件），好清爽，哈哈哈

Homebrew

Mac上的软件包管理工具，能在Mac中方便的安装软件或者卸载软件，可以说Homebrew就是mac下的apt-get、yum神器
https://brew.sh/
以下是官方说的安装方式，复制粘贴到命令行回车即可

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

常规使用

搜索软件：brew search 软件名，如brew search git
安装软件：brew install 软件名，如brew install git
卸载软件：brew remove 软件名，如brew remove git
软件列表：brew list

git

brew install git

Java

官方下载安装包直接安装
是下载JDK(内有JRE)，不是下载JRE
安装完可以在命令行检验一下

java -version
java version "10.0.1" 2018-04-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.1+10, mixed mode)

node

官网下载安装没啥好说的

mysql

brew install mysql

设置开机启动

ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents

启动mysql

Y:~ hongxi$ mysql.server start
Starting MySQL
. SUCCESS!

设置密码

mysql_secure_installation

运行mysql_secure_installation会执行以下几个设置：
a)为root用户设置密码
b)删除匿名账号
c)取消root用户远程登录
d)删除test库和对test库的访问权限
e)刷新授权表使修改生效

Y:~ hongxi$ mysql_secure_installation

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

There are three levels of password validation policy:

LOW    Length >= 8
MEDIUM Length >= 8, numeric, mixed case, and special characters
STRONG Length >= 8, numeric, mixed case, special characters and dictionary                  file

Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 0
Please set the password for root here.

New password:

Re-enter new password:

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) : y
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.


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.

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.

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
Success.

All done!
