搜索:
brew search mysql
安装早期版本,brew link可以理解为简易的配置环境变量的方式
brew install [email protected]
brew link [email protected]
安装新版本,不需要link
brew install mysql
启动和停止:
mysql.server start
mysql.server stop
看mysql查找my.cnf (windows系统下熟知的my.ini在mac中不用)的顺序是如何
mysqld --help --verbose | more
会得到如下内容:

Starts the MySQL database server.
Usage: mysqld [OPTIONS]
Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /opt/homebrew/etc/my.cnf ~/.my.cnf
The following groups are read: mysqld server mysqld-8.0
The following options may be given as the first argument:
--print-defaults Print the program argument list and exit.
--no-defaults Don't read default options from any option file,
except for login file.
--defaults-file=# Only read default options from the given file #.
--defaults-extra-file=# Read this file after the global files are read.
--defaults-group-suffix=#
Also read groups with concat(group, suffix)
--login-path=# Read this path from the login file.
其中
Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /opt/homebrew/etc/my.cnf ~/.my.cnf
就是mysql本体查找配置文件的顺序,一般在/opt/homebrew/etc/就存在当前的配置,并且该目录下还有一个default配置文件.
如果在/etc/中创建my.cnf,则会优先使用这个配置.
WordPress从mysql5.7之前版本导入的数据到mysql8时会出现
Invalid default value for 字段名称
这样的错误.看错误语句可以发现是0000-00-00 00:00:00这样的时间格式不正确的原因.
虽然在mysql的链接session下临时使用
set session sql_mode='ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
可以更改配置但是通常我们使用navicat这样的工具做数据迁移时,他可能和query不走一个session,我测试在navica的查询中使用如上命令然后再执行数据传输工具并不可用.
修改my.cnf,增加配置
sql_mode=ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION
其他的诸如改端口号之类的配置也都在这文件了.
重启mysql服务
mysql.server restart
