在MAC OS X上安装MYSQL
我在网上找到了一篇文章,简直堪称神器。 刚开始用brew search mysql ...能找到,按照提示一步一步安装,结果到最后就是启动不起来,老提示一个sock相关的错误。。 后来我还是直接到mysql 的官网下载了适合MAC 平台的 mysql-5.5.17-osx10.6-x86_64.dmg 打开

刚开始用brew search mysql ...能找到,按照提示一步一步安装,结果到最后就是启动不起来,老提示一个sock相关的错误。。
后来我还是直接到mysql 的官网下载了适合MAC 平台的 mysql-5.5.17-osx10.6-x86_64.dmg
打开后发现3个文件,安装顺序:
1。mysql-5.5.17-osx10.6-x86_64.pkg 数据库
2。MySQLStartupItem.pkg 这样MySQL就会自动在开机时自动启动了。
3。MySQL.prefPane 这样就会在“系统设置偏好”中看到名为“MySQL”的ICON,通过它就可以设置MySQL开始还是停止,以及是否开机时自动运行。到这里MySQL就基本安装完毕了。
通过运行“sudo vi /etc/bashrc”,在bash的配置文件中加入mysql和mysqladmin的别名
#mysql
alias mysql='/usr/local/mysql/bin/mysql'
alias mysqladmin='/usr/local/mysql/bin/mysqladmin'
这样就可以在终端中比较简单地通过命令进行相应的操作,比如安装完毕之后MySQL的root默认密码为空,如果要设置密码可以在终端运行“mysqladmin -u root password "mysqlpassword"”来设置,其中mysqlpassword即root的密码。
备注:使用PHP连接MySQL可能会报错“Can't connect to local MySQL server through socket ‘/var/mysql/mysql.sock'”,或者使用localhost无法连接MySQL而需要127.0.0.1,原因是连接时候php默认去找/var/mysql/mysql.sock了,但是MAC版本的MYSQL改动了文件的位置,放在/tmp下了。处理办法是按如下修改php.ini:
mysql.default_socket = /tmp/mysql.sock
以上所言,没有一句废话,十分佩服!

Abstract of the first paragraph of the article: When choosing software to develop Yi framework applications, multiple factors need to be considered. While native mobile application development tools such as XCode and Android Studio can provide strong control and flexibility, cross-platform frameworks such as React Native and Flutter are becoming increasingly popular with the benefits of being able to deploy to multiple platforms at once. For developers new to mobile development, low-code or no-code platforms such as AppSheet and Glide can quickly and easily build applications. Additionally, cloud service providers such as AWS Amplify and Firebase provide comprehensive tools
