Install and configure MySQL 5 with MacPorts
转自：http://beike.iteye.com/blog/617341I decided to move my MySQL server installation from the server I installed from MySQL.com to macports. Why? I believe MacPorts will simplify future upgrades. I'd also like to keep my LAMP installs in the same location. If you haven't already, install and configure MacPorts. Here are the steps I'll go over:
Intall MySQL 5Create the initial MySQL databasesOptions for starting MySQLConfirm that MySQL is runningSet Basic MySQL SecurityInstall MySQL 5You can install using Porticus, Port Authority, or from the command line:
?
The +server variant is required if you'll need to create a system startup item for MySQL 5. You'll see plenty of output during the build process and an activation message just before the installation completes.
Create initial MySQL databasesMySQL databases are kept in /opt/local/var/db/mysql5/ and you'll notice that this directory is empty. Run mysql_install_db to create the mysql and test databases.
Password:
You should see output similar to the following:
?
Options for starting MySQLI personally don't want MySQL to start at system start up, I'll start it manually when I need it. If you're energy conscious and set your Mac to go to sleep you won't want to set mysqld to start at system boot either. If, however, you need MySQL to always start at system boot
sudo launchctl load -w /Library/LaunchDaemons/org.macports.mysql5.plist
?
Whether you install the startup item or not, it's handy to add aliases to your profile to start and stop mysql from the command line. Use your favorite text editor (vi, pico, emacs) to add aliases.
vi ~/.profile
or
vi ~/.bash_profile
Add the following:
Note: Notice the '5' at the end of mysqld_safe? MacPorts adds version numbers at the end of executables to allow the installation of multiple versions (i.e. MySQL 4 and 5). You'll need to add the version number at the end of some of the executables you use, like mysqladmin5. Now you're ready to start your MySQL server with:
mysqlstart
or, if you didn't create aliases
sudo /opt/local/share/mysql5/mysql/mysql.server start
If MySQL's okay, you should see a server start confirmation message. You can test to ensure that MySQL is running with (leave password empty when prompted):
mysqladmin5 -u root -p ping ?Enter password: ?mysqld is alive
or with
mysql5 -u root -p Enter password: ?
Welcome to the MySQL monitor. ?Commands end with ; or \g. Your MySQL connection id is 2 to server version: 5.0.45 ?Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
If you get the following error...
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
...set the mysqld_safe socket path in a new MySQL configuration file. Create /opt/local/etc/mysql5/my.cnf, add the following to it, save, the try again.
[mysqld_safe] socket = /tmp/mysql.sock
NOTE: If you've installed MacPort's PHP 5 you will probably need to tell PHP where the MySQL socket is. Edit your php.ini file located at /opt/local/etc/php.ini.
mysql.default_socket = /tmp/mysql.sock
Finally, set the root mysql password to secure your server.
mysqladmin5 -u root password
If, like me, you want to move data from a previous MySQL 5 install (i.e. /usr/local/mysql/data), be sure to stop MySQL first. You'll want to overwrite the mysql database you created after installation when copying over data files and indices. Ensure that everything copied to /opt/local/var/db/mysql5/ remains owned by mysql. Refer to the MySQL documentation if you're upgrading from MySQL 4 to 5.
Now get busy querying.
