摘要：本文记录在Mac OS X 10.9.1(x86, 64-bit)上配置MySQL数据库的安装过程，以及记录的一些问题。

0 下载

打开官网地址 http://www.mysql.com/ ，然后点击 Downloads (GA) 进入下载页面，其中commercial是商业付费的，GPL(https://www.gnu.org/copyleft/gpl.html)是开源免费的，所以找到Mysql Community Edition(GPL) 点击进入可以找到下面这个下载链接：

进入后可以看到关于“
Download MySQL Community Server 
”的一段描述：
“MySQL Community Edition is a freely downloadable version of the world's most popular open source database that is supported by an active community of open source developers and enthusiasts.”

并在下面可以看到网页自动识别出当前的操作系统对应的MySQL版本：

在这里并没有找到最新的Mac OS X 10.9所对应的版本（当前OS的版本可以通过 sw_vers 命令查看）：

gerryyang@mba:MySQL$sw_vers

ProductName:Mac OS X

ProductVersion:10.9.1

BuildVersion:13B42

然后，google了一下在github上找到一个Mac上自动安装MySQL的脚本，发现作者用的也不是最新的版本而是10.7的dmg版本，关于此脚本的用法，作者的一些文章介绍链接如下：

“

Automation scripts focused around Mac OS X Server 

Install MySQL on OS X 10.9 Mavericks

Install MySQL on Mountain Lion

https://raw.github.com/MacMiniVault/Mac-Scripts/master/mmvMySQL/mmvmysql.sh

”

下文继续使用官方提供的链接进行安装（注释：这里使用的是二进制的安装方式），脚本的方法这里不讨论（脚本中的下载链接：http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.15-osx10.7-x86_64.dmg）。

下载过程有点慢，可以使用shutdown命令设定关机或休眠：

gerryyang@mba:Volumes$sudo shutdown -s 1402150045

Password: Shutdown at Sat Feb 15 00:45:00 2014.
shutdown: [pid 5261]
如果想取消自动关机，使用 sudo kill pid 命令即可。

1 安装

下文假设已经下载完毕。为了叙述方便，下文采用命令交互的方法记录整个安装和测试过程：

(1) MySQL的INSTALL_BINARY安装说明建议创建一个mysql User and Group，OS X的命令和Linux的有所不同，通过下面命令可以创建：

# 创建mysql用户
dscl . -create /Users/mysql
# 设置使用的shell
dscl . -create /Users/mysql UserShell /bin/bash
# 设置用户home目录
dscl . -create /Users/mysql NFSHomeDirectory /Users/mysql
# 设置密码
dscl . -passwd /Users/mysql mysql


(2) 对MySQL进行初始化，创建系统需要的表。This scripts creates the MySQL Server system tables.

root@mba:mysql-5.6.16-osx10.7-x86#scripts/mysql_install_db --user=mysql

(3) 使用root用户启动MySQL，并通过ps查看进程是否正常被拉起

gerryyang@mba:mysql-5.6.16-osx10.7-x86$su root
Password:
root@mba:mysql-5.6.16-osx10.7-x86#bin/mysqld_safe &

root@mba:mysql-5.6.16-osx10.7-x86#ps aux | grep mysql | grep -v grep
_mysql           8757   0.0 10.4  1211616 435524 s001  S     7:46下午   0:00.39 /Users/gerryyang/LAMP/MySQL/mysql-5.6.16-osx10.7-x86/bin/mysqld --basedir=/Users/gerryyang/LAMP/MySQL/mysql-5.6.16-osx10.7-x86 --datadir=/Users/gerryyang/LAMP/MySQL/mysql-5.6.16-osx10.7-x86/data --plugin-dir=/Users/gerryyang/LAMP/MySQL/mysql-5.6.16-osx10.7-x86/lib/plugin --user=mysql --log-error=/Users/gerryyang/LAMP/MySQL/mysql-5.6.16-osx10.7-x86/data/mba.local.err --pid-file=/Users/gerryyang/LAMP/MySQL/mysql-5.6.16-osx10.7-x86/data/mba.local.pid

root@mba:mysql-5.6.16-osx10.7-x86#

(4) 使用kill -9 pid干掉MySQL，这里要先把mysqld_safe进程干掉，然后再把mysql进程干掉，否则mysql会被重新拉起

root@mba:mysql-5.6.16-osx10.7-x86#kill -9 8679
root@mba:mysql-5.6.16-osx10.7-x86#ps aux | grep mysql | grep -v grep
_mysql           8757   0.0 10.4  1211616 435524 s001  S     7:46下午   0:00.45 /Users/gerryyang/LAMP/MySQL/mysql-5.6.16-osx10.7-x86/bin/mysqld --basedir=/Users/gerryyang/LAMP/MySQL/mysql-5.6.16-osx10.7-x86 --datadir=/Users/gerryyang/LAMP/MySQL/mysql-5.6.16-osx10.7-x86/data --plugin-dir=/Users/gerryyang/LAMP/MySQL/mysql-5.6.16-osx10.7-x86/lib/plugin --user=mysql --log-error=/Users/gerryyang/LAMP/MySQL/mysql-5.6.16-osx10.7-x86/data/mba.local.err --pid-file=/Users/gerryyang/LAMP/MySQL/mysql-5.6.16-osx10.7-x86/data/mba.local.pid

root@mba:mysql-5.6.16-osx10.7-x86#ps aux | grep mysql | grep -v grep
root@mba:mysql-5.6.16-osx10.7-x86#bin/mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (61)

(5) 为了方便，将MySQL/bin加入PATH环境变量中，修改用户home目录下的.bashrc文件，添加如下内容，然后在终端执行 . .bashrc 命令使其生效
# MySQL
export MYSQL_PATH=/Users/gerryyang/LAMP/MySQL/mysql-5.6.16-osx10.7-x86
export PATH=$PATH:$MYSQL_PATH/bin
