MacBook 装置 Mysql
Mysql 官网下载地址: https://dev.mysql.com/downloa…
官网下载 MySQL Community Server 社区版
抉择对应的版本和零碎下载: mysql-5.7.22-macos10.13-x86_64.dmg
点击装置 留神装置过程会弹出 明码 须要记住明码
在设置里最上面找到 mysql 关上后启动，这里我把开机主动启动给去掉了
#Mysql 命令增加到环境变量里
vim ~/.zshrc
#最初退出
export MYSQL_HOME=/usr/local/mysql
export PATH=$MYSQL_HOME/bin:$PATH
#使配置失效
source ~/.zshrc
#查看 mysql 版本
mysql —version
#批改明码
mysql -u root -p
#输出之前保留的明码
#设置新密码 如:123456
SET PASSWORD FOR 'root'@'localhost'=PASSWORD('123456');
#设置近程连贯受权
grant all privileges on *.* to 'root'@'%' identified by '123456';
flush privileges;
#批改 mysql 配置 查看编码
show variables like '%char%';
#新版本的 mysql 装置目录下没有默认配置文件了 /usr/local/mysql/support-files 能够从其余中央复制一份过去mysql 配置文件
sudo vim /etc/my.cnf
#查看配置
cat my.cnf
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
