1、按照常规安装。 [root@ff_girl mysql5122]# chown -R root . [root@ff_girl mysql5122]# chown -R mysql data [root@ff_girl mysql5122]# chgrp -R mysql . [root@ff_girl mysql5122]# cp support-files/my-small.cnf /etc/my5122.cnf [root@ff_girl mysql5122]# scripts/mysql_install_db --basedir=/usr/local/mysql5122/ --datadir=/usr/local/mysql5122/data/ --user=mysql Installing MySQL system tables... OK Filling help tables... OK
To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system
。。。 首次启动MYSQL [root@ff_girl mysql5122]# bin/mysqld_safe --defaults-file=/etc/my5122.cnf & [1] 13700 [root@ff_girl mysql5122]# 080124 15:01:46 mysqld_safe Logging to '/usr/local/mysql5122/data/localhost.localdomain.err'. 080124 15:01:46 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql5122/data
[root@ff_girl mysql5122]# bin/mysql -uroot -p -S/tmp/mysql5122.sock Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 1 Server version: 5.1.22-rc MySQL Community Server (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | test | +--------------------+ 3 rows in set (0.00 sec) 给MYSQLD_MULTI赋SHUTDOWN权限。 mysql> grant shutdown on *.* to multi_admin@'localhost' identified by '123456'; Query OK, 0 rows affected (0.00 sec)
mysql> exit Bye 停掉MYSQL服务。 [root@ff_girl ~]# /usr/local/mysql5122/bin/mysqladmin -uroot -p -S/tmp/mysql5122.sock shutdown Enter password: [root@ff_girl ~]# 拷贝元数据。 [root@ff_girl mysql5122]# cp data data2 [root@ff_girl mysql5122]# mv data data1 [root@ff_girl mysql5122]# chown -R mysql data2 [root@ff_girl mysql5122]# chgrp -R mysql .
示例配置文件
[root@ff_girl mysql5122]# cat /etc/my5122.cnf [mysqld_multi] mysqld = /usr/local/mysql5122/bin/mysqld_safe mysqladmin = /usr/local/mysql5122/bin/mysqladmin user = multi_admin password = 123456 # The MySQL server [mysqld1] socket = /tmp/mysql1.sock port = 3307 pid-file = /usr/local/mysql5122/data1/david_yeung.pid1 datadir = /usr/local/mysql5122/data1 language = /usr/local/mysql5122/share/mysql/english user = mysql # The MySQL server [mysqld2] port = 3308 socket = /tmp/mysql2.sock pid-file = /usr/local/mysql5122/data2/david_yeung.pid2 datadir = /usr/local/mysql5122/data2 language = /usr/local/mysql5122/share/mysql/english user = mysql 。。。 [isamchk] key_buffer = 8M sort_buffer_size = 8M
启动两个MYSQL服务 [root@ff_girl mysql5122]# /usr/local/mysql5122/bin/mysqld_multi --config-file=/etc/my5122.cnf start 1-2 [root@ff_girl mysql5122]# netstat -an | grep 3307 tcp 0 0 0.0.0.0:3307 0.0.0.0:* LISTEN [root@ff_girl mysql5122]# netstat -an | grep 3308 tcp 0 0 0.0.0.0:3308 0.0.0.0:* LISTEN [root@ff_girl mysql5122]# /usr/local/mysql/bin/mysql -uroot -p -S/tmp/mysql1.sock Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 1 Server version: 5.1.22-rc-log MySQL Community Server (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql> \q Bye [root@ff_girl mysql5122]# /usr/local/mysql/bin/mysql -uroot -p -S/tmp/mysql2.sock Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 1 Server version: 5.1.22-rc-log MySQL Community Server (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql> \q Bye [root@ff_girl mysql5122]#
2、另外一种。 [root@ff_girl mysql512]# chown -R root . [root@ff_girl mysql512]# chown -R mysql data [root@ff_girl mysql512]# chgrp -R mysql . [root@ff_girl mysql512]# scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql512/ --datadir=/usr/local/mysql512/data/ [root@ff_girl mysql512]# cp support-files/my-huge.cnf /etc/my512.cnf 并且修改如下部分。 [client] port = 3308 socket = /tmp/mysql512.sock
# The MySQL server [mysqld] user=mysql basedir=/usr/local/mysql512 datadir=/usr/local/mysql512/data port = 3308 socket = /tmp/mysql512.sock
[root@ff_girl mysql512]# /usr/local/mysql512/bin/mysqld_safe --defaults-file=/etc/my512.cnf & [root@ff_girl mysql512]# /usr/local/mysql/bin/mysql -uroot -p -S/tmp/mysql512.sock Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 1 Server version: 5.1.22-rc-log MySQL Community Server (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | test | +--------------------+ 3 rows in set (0.00 sec)
