这里要说的是删除 mac 启动台里删除不掉的图标的方法。既然要说,肯定是常规方法删除不掉的,比如按住 option 删除,比如进入访达删除这些。

步骤如下:

# command + 空格键,输入终端,打开终端。或你有 item2 更好。

cd /private/var/folders/
sudo find ./ -name com.apple.dock.launchpad # 找到该文件夹,然后进入。我自己的是下边这样的。
cd .//_2/bnb9_37n7j18jmp5zw7b8by00000gn/0/com.apple.dock.launchpad
cd db

# 然后执行下边的命令,回车删除
sqlite3 db "delete from apps where title='adobe_licensing_helper';"&&killall Dock

通过以上几个步骤就可以完成删除操作了。如下图所示:

再来看看对比图

这个是真删除了,不是我移到外边去了。

如果想在mac下使用windows,用虚拟机安装windows是一个不错的选择。比装双系统好多了。想用就用,不要就卸,就跟安装软件卸载软件一样方便。虚拟机容器比较多,有vm,pd,vbox。因为之前用vbox安装了homestead,那么就用vbox来装windows。

下载windows镜像

https://msdn.itellyou.cn/ 这里有你想要的windows版本,xp,vista,win7,win10,server等。个人比较中意win7,这里选择win7 64位旗舰版。

Node.js 官网下载地址:https://nodejs.org/en/download/

注意,这里分两种版本,LTS(长期支持,成熟可靠)和Current(稳定版,最新特性)。选择合适的版本安装。

下载好Mac对应的版本。然后安装。安装完成后,会出现下边提示。

Node.js was installed at

   /usr/local/bin/node

npm was installed at

   /usr/local/bin/npm

Make sure that /usr/local/bin is in your $PATH.

确定,安装完成。

使用

安装完成后,可以在终端中查看版本。

node -v
npm -v

使用国内的淘宝镜像

npm install -g cnpm --registry=https://registry.npm.taobao.org

安装redis

brew install redis

安装成功后,有如下提示

zhoulindeMacBook-Pro:~ zhoulin$ brew install redis
==> Downloading https://mirrors.ustc.edu.cn/homebrew-bottles/bottles/redis-4.0.1.sierra.bottle.tar.gz 

######################################################################## 100.0%
==> Pouring redis-4.0.1.sierra.bottle.tar.gz
==> Caveats
To have launchd start redis now and restart at login:
  brew services start redis
Or, if you don't want/need a background service you can just run:
  redis-server /usr/local/etc/redis.conf
==> Summary
  /usr/local/Cellar/redis/4.0.1: 13 files, 2.8MB
zhoulindeMacBook-Pro:~ zhoulin$ brew services start redis

然后按照提示,启动redis

开机自启动

sudo cp /usr/local/opt/redis/homebrew.mxcl.redis.plist ~/Library/LaunchAgents/
sudo launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.redis.plist 
sudo launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.redis.plist #停止使用

直接进入主题。

brew install mariadb

安装成功后,会有下边的提示。

A "/etc/my.cnf" from another install may interfere with a Homebrew-built
server starting up correctly.

MySQL is configured to only allow connections from localhost by default

To connect:
    mysql -uroot

To have launchd start mariadb now and restart at login:
  brew services start mariadb
Or, if you don't want/need a background service you can just run:
  mysql.server start
==> Summary
  /usr/local/Cellar/mariadb/10.2.7_1: 623 files, 162.2MB

进入安装目录,进行配置。

cd /usr/local/cellar/mariadb/10.2.7_1
mysql_install_db 

经过了上面的若干命令,已经安装好了mariadb数据库,但是mariadb数据库服务并没有启动,你可以通过这个命令来启动mariadb数据库服务:

mysql.server start 

通过上面的启动mariadb数据库服务,你已经可以连接mariadb的数据库了,但是还不够安全,通过如下步骤可以完成更全面的设置,如:重设root用户的密码、移除匿名用户、移除默认的test数据库等等。

zhoulindeMacBook-Pro:10.2.7_1 zhoulin$ mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): 
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] y
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB 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? [Y/n] 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? [Y/n] y
 ... Success!

By default, MariaDB 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? [Y/n] n
 ... skipping.

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

连接mariadb数据:

mysql -u root -p 

这个时候,输入上一步设置的密码,回车,就可以连接到mariadb了。

验证mariadb版本:

MariaDB [(none)]> select @@version;
+----------------+
| @@version      |
+----------------+
| 10.2.7-MariaDB |
+----------------+
1 row in set (0.00 sec)

mariadb基础命令:

下面是mariadb的一些基础使用命令:

显示数据库列表
show databases;

切换到名为mysql的数据库,显示该库中的数据表
use mysql;
show tables;

显示数据表table的结构
desc table;

建数据库A与删数据库A
create database database_A;
drop database database_A;

建表:
use database_A;
create table table_A(字段列表);
drop table table_A;

显示表中的记录:
select * from table_A;

清空表中记录:
delete from table_A;

mariadb 自启动

sudo cp /usr/local/cellar/mariadb/10.2.7_1/homebrew.mxcl.mariadb.plist ~/Library/LaunchAgents/
sudo launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mariadb.plist #启动
sudo launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mariadb.plist #关闭

通常,域名访问的网站都是外网的。有时候为了方便,使用域名访问本地文件也有必要。要实现这个,做到以下两步即可。

  1. 写host。
  2. 修改服务器配置。这里用的是 nginx

  3. 如果想要使用 https 访问,还需要制作 ssl 证书。

但在 mac 下,要实现这个,必须先实现端口的转发。也就是mac限制root权限才可以访问1024以下端口。所以,你想访问80端口,443端口是不现实的。这个时候,就需要用到 pfctl 转发。

实现了转发,就继续下边的过程了。
