mac 下mysql安装

系统环境: OS X Yosemite 10.10.3

登录用户: fx (有 sudo 权限)

MySQL版本: 5.5.49 (mysql-5.5.49-osx10.9-x86_64.tar)

MySQL下载: http://dev.mysql.com/downloads/mysql/

找到下载的 MySQL tar.gz 文件位置, 浏览器下载的一般在当前用户的 Downloads 目录, 即 /Users//Downloads,进入终端, 解压 tar.gz 文件:

cd /Users//Downloads

tar zxvf mysql-5.6.24-osx10.9-x86_64.tar.gz

解压完成后得到 mysql-5.5.49-osx10.9-x86_64 目录, 移动解压目录到 MySQL 默认安装路径 /usr/local/mysql下, /usr/local 路径不存在时,

先 sudo mkdir /usr/local 创建。

# 移动解压后的二进制包到安装目录

sudo mv mysql-5.5.49-osx10.9-x86_64 /usr/local/mysql

# 更改 mysql 安装目录所属用户与用户组

cd /usr/local

sudo chown -R root:wheel mysql

# 执行 scripts 目录下的mysql_install_db 脚本完成一些默认的初始化(创建默认配置文件、授权表等)

cd /usr/local/mysql

sudo scripts/mysql_install_db --user=mysql

注意: MySQL 5.7.6 以上版本取消了 scripts 目录, 初始化命令改成了

sudo bin/mysqld --initialize --user=mysql

安装完成, 测试启动、重启与停止:

cd /usr/local/mysql

# 启动

sudo support-files/mysql.server start

# 重启

sudo support-files/mysql.server restart

# 停止

sudo support-files/mysql.server stop

# 检查 MySQL 运行状态

sudo support-files/mysql.server status

一、初始化 MySQL root 密码

# 需要 MySQL 服务在运行状态执行

cd /usr/local/mysql/bin

./mysqladmin -u root -p password 新密码

#输入生成的临时密码，回车

修改成功会返回:

mysqladmin: [Warning] Using a password on the command line interface can be insecure.

Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.

连接登陆到mysql：

cd mysql/bin

./mysql -u root -p

#输入密码

登陆成功:
