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
