1.1.1 安装mysql

1)查找可安装的mysql

port search mysql

2)安装mysql5

sudo port install mysql5-server

\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#

\# A startup item has been generated that will aid in

\# starting mysql5-server with launchd. It is disabled

\# by default. Execute the following command to start it,

\# and to cause it to launch at startup:

\# sudo port load mysql5-server

\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#

\---> Installing mysql5-server @5.1.50\_0

\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*

\* In order to setup the database, you might want to run

\* sudo -u \_mysql mysql\_install\_db5

\* if this is a new install

\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*

\---> Activating mysql5-server @5.1.50\_0

\---> Cleaning mysql5-server

3)安装mysql的初始库。

sudo /opt/local/lib/mysql5/bin/mysql\_install\_db --user=mysql

Installing MySQL system tables...

Filling help tables...

To start mysqld at boot time you have to copy

support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

To do so, start the server, then issue the following commands:

/opt/local/lib/mysql5/bin/mysqladmin -u root password 'new-password'

/opt/local/lib/mysql5/bin/mysqladmin -u root -h bogon password 'new-password'

Alternatively you can run:

/opt/local/lib/mysql5/bin/mysql\_secure\_installation

which will also give you the option of removing the test

databases and anonymous user created by default. This is

strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

cd /opt/local ; /opt/local/lib/mysql5/bin/mysqld\_safe &

You can test the MySQL daemon with mysql-test-run.pl

cd /opt/local/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /opt/local/lib/mysql5/bin/mysqlbug script!

1.1.2 配置mysql

1)设置和取消开机时自动启动mysql

设置开机自动启动mysql：

sudo launchctl load -w /Library/LaunchDaemons/org.macports.mysql5.plist

取消开机自动启动mysql的命令好象是下面的命令，在网上看到过，但后来找不到了：

sudo launchctl load -w /Library/LaunchDaemons/org.macports.mysql5.plist

2)通过alias启动mysql

为了简化在命令行中启动和关闭mysql的命令，可以通过设置aliases来实现，aliases就象windows中的快捷方式：

打开这个配置文件，输入以下内容：

mate ~/.profile

alias mysqlstart='sudo /opt/local/bin/mysqld\_safe5 &'

alias mysqlstop='/opt/local/bin/mysqladmin5 -u root -p shutdown'

通过命令启动mysql：

mysqlstart

\[1\] 62478

如果没有设置aliases，则用以下命令来启动

/opt/local/share/mysql5/mysql/mysql.server start

3)验证mysql安装成功

通过以下命令来登录mysql：

mysqladmin5 -u root -p ping

或

mysql5 -u root –p

但很不幸，在执行

mysqladmin5 -u root -p ping

报以下错误：

error: 'Can't connect to local MySQL server through socket '/opt/local/var/run/mysql5/mysqld.sock' (2)'

Check that mysqld is running and that the socket: '/opt/local/var/run/mysql5/mysqld.sock' exists!

而执行 mysql5 -u root –p时报以下错误

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/opt/local/var/run/mysql5/mysqld.sock' (2)

在上面找到的文章中发现也有提到这个问题，于是按照文章中的步骤来试着解决(参考 http://beike.iteye.com/blog/617341 )：

mate /opt/local/etc/mysql5/my.cnf并输入以下内容：

\[mysqld\_safe\]

socket = /tmp/mysql.sock

但是修改完后执行mysql5 -u root –p还是报相同错误。

后来在iteye.com上提问找到了答案( http://www.iteye.com/problems/49993)。在启动时要增加参数-host 127.0.0.1，用下面命令就可以启动了：

mysql5 -u root –host 127.0.0.1 –p

4)修改root帐户密码

mysqladmin5 -u root -h 127.0.0.1 password "ilovebritney"

1.2、从mysql官网上下载安装包进行安装

一开始我是通过macport来安装mysql的，但在后面进行rails开发时无法连接上数据库，google后知道在mac osx 10.6上要安装64bit的mysql，于是又用这个方法重新安装了一遍，如果在后面的文章中提到相应的错误时，请反回来看这小节。刚好昨天去听管理人课程知道员工的水平是折腾出来的，所以有了以下的折腾出来的经验。

1.2.1 卸载已经安装过的mysql

通过以下命令或步骤来卸载已经安装过的mysql(参考http://qingbo.net/picky/510-snowleopard-ruby-mysql.html)：

关掉 MySQL Server

sudo rm /usr/local/mysql

sudo rm -rf /usr/local/mysql\*

sudo rm -rf /Library/StartupItems/MySQLCOM

sudo rm -rf /Library/PreferencePanes/My\*

编辑文件 /etc/hostconfig，删掉这一行：MYSQLCOM=-YES-

rm -rf ~/Library/PreferencePanes/My\*

sudo rm -rf /Library/Receipts/mysql\*

sudo rm -rf /Library/Receipts/MySQL\*

1.2.2 安装mysql

参考(http://2015.iteye.com/blog/615152和http://hi.baidu.com/beyond\_javy/blog/item/9d884a8259c19baf0df4d224.html)

1)下载安装包

从mysql官网上下载安装包mysql-5.1.50-osx10.6-x86\_64.dmg进行安装。

2)安装mysql

双击mysql-5.1.50-osx10.6-x86\_64.pkg进行mysql安装。

3)安装自动启动项目

双击MySQLStartupItem.pkg进行mysql启动项目，安装完之后就可以在电脑启动系统时自动运行mysql服务，它安装在/Library /StartupItems/MySQL/。如果你不想系统启动时运行mysql服务，请不要安装。如果你在安装后又不想使用，请删除/Library /StartupItems/MySQL/这个目录。

4)  安装系统偏好设置里的设置项

双击MySQL.prefPane，安装完后会在系统偏好增加一个mysql设置项，可以通过它来启动和关闭MySQL。

1.2.3 配置mysql

1)修改root帐户密码

执行这个命令可以修改mysql的密码：

/usr/local/mysql/bin/mysqladmin -u root password ilovebritney

2) 通过alias启动mysql

如果要快捷启动，则要先设置aliases，再用aliases来启动：

mate ~/.profile

alias mysql='/usr/local/mysql/bin/mysql'

alias mysqladmin='/usr/local/mysql/bin/mysqladmin'

以后就可以直接用mysql和mysqladmin来进行操作了。

3)登录mysql

通过mysql -u root –p来登录mysql。

4)修改mysql密码

mysqladmin -u root password ilovebritney

一般不用rvm和homebrew的 基本属于还没入门的mac/rubyist

这个也看到过，但之前一直用macport，而且brew跟macport也是一个性质的东西，就没有用它了。
