mac下用brew安装 mysql

1. 经过homebrew安装mysql，目前默认安装最新版本，若是要安装其余版本，需指定版本号

brew  install mysql@5.6
复制代码

2. 修改配置文件

vim /usr/local/etc/my.cnf

# Default Homebrew MySQL server config
[client]
port = 3306
socket = /tmp/mysql.sock
default-character-set = utf8

[mysqld]
collation-server = utf8_unicode_ci
character-set-server = utf8
init-connect ='SET NAMES utf8'
max_allowed_packet = 64M
bind-address = 127.0.0.1
port = 3306
socket = /tmp/mysql.sock
skip-grant-tables
复制代码

3. 启动服务

brew services start mysql@5.6 
brew services restart mysql@5.6  #重启
brew services stop mysql@5.6     #中止
复制代码

4. 链接数据库

mysql -u root -p
复制代码
