Mac下安装mysql及简单错误处理

1. 首先安装Homebrew

打开终端， 输入以下一行命令，等着下载完成。顺带一提， homebrew是Mac下的一款下载神器。

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

2. 开始下载mysql

还是使用终端，输入以下一行命令

brew install mysql

3. 然后就等着

看网速了，网速好，几分钟就下好了，网速差就多等会，下载好了后差不多就会如下图所示，注意 红框框 里面写的，就是下一步

4. 在终端输入mysql_secure_installation

输入完msyql_secure_installation后，会让你做一些设置密码类的简单操作，密码最好由字母、符号和数字组成，不然好像系统会觉得你密码不够安全，会让你重输入，这个密码需要记住， 以后要用的。

luoputekiMacBook-Air:~ luopu$ mysql_secure_installation
Securing the MySQL server deployment.
Enter password for user root: # 输入密码
The 'validate_password' plugin is installed on the server.
The subsequent steps will run with the existing configuration
of the plugin.
Using existing password for root.
Estimated strength of the password: 100
Change the password for root ? ((Press y|Y for Yes, any other key for No) : n    # 选no就行了， 不用改，就是刚刚的密码
... skipping.
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       # 移除匿名用户
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   # 禁止远程登陆
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      # 删除测试数据库
- 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     # 刷新一下
Success.
All done!
luoputekiMacBook-Air:~ luopu$

5. 搞定 + 进入mysql

luoputekiMacBook-Air:~ luopu$ mysql.server start  # 启动mysql服务
Starting MySQL
. SUCCESS!
luoputekiMacBook-Air:~ luopu$ mysql -uroot -p  # 相当于你即将进入一个可执行sql语句的地方
Enter password:  # 输入之前设置的密码

6. 简单错误处理

错误一

ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)



这个是因为mysql.server 没启动， 输入以下命令，回车

mysql.server start

错误二

luoputekiMacBook-Air:~ luopu$ mysql -v

ERROR 1045 (28000): Access denied for user ‘luopu’@’localhost’ (using password: NO)



这个是因为’luopu’没有权限，mysql下有个超级用户’root’,可以使用root解决该错误。举例：将图片中的

mysql -v

改为

mysql -uroot -p -v

即可。

错误三

ERROR 1064 (42000) at line 1: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘rsion’ at line 1



在你写的sql语句中的

rsion

附近由语法错误。
