使用MacPorts安装MySQL5, 比较喜欢MacPorts的管理方式

开始我用AppZapper删除了dmg版本，以为都删掉了，捣腾了好久，几次不成功，是因为dmg版本的干扰，装好后启动了原来dmg版本，有点囧。哎

安装方法：

ericdemacbook:~ Eric$ sudo port install mysql5-server
--->  Fetching mysql5
--->  Verifying checksum(s) for mysql5
--->  Extracting mysql5
--->  Applying patches to mysql5
--->  Configuring mysql5
--->  Building mysql5
--->  Staging mysql5 into destroot
--->  Installing mysql5 @5.0.84_0
--->  Activating mysql5 @5.0.84_0
--->  Cleaning mysql5

ericdemacbook:~ Eric$ sudo -u mysql mysql_install_db5

ericdemacbook:~ Eric$ sudo /opt/local/bin/mysqld_safe5 &
[1] 53056
ericdemacbook:~ Eric$ Starting mysqld daemon with databases from /opt/local/var/db/mysql5

为了不方便使用，把下面aliases内容添加到 .profile，

ericdemacbook:~ Eric$ vim .profile

alias mysqlstart='sudo /opt/local/bin/mysqld_safe5 &'
alias mysqlstop='/opt/local/bin/mysqladmin5 -u root -p shutdown'

因为不喜欢每次开机都自动运行， 需要用的时候才打开，（PS:

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