同一台MySQL服务器启动多个端口

wget  二进制的源码包

解压
cat INSTLL-BINARY
根据说明操作，具体安装步骤请看 http://www.lishiming.net/thread-7-1-1.html
其中1-4步骤是相同的，第5步，也是最重要的一步，要初始化数据库
因为是多个端口，所以要根据配置文件来初始化多个数据库
比如说有2个端口
则要运行两次
./scripts/mysql_install_db --datadir=/home/mysql1 --user=mysql
./scripts/mysql_install_db --datadir=/home/mysql2 --user=mysql

配置文件要编辑成这样
[mysqld0]
port            = 3300
socket          = /tmp/mysql0.sock
pid-file        = /home/mysql0/localhost.localdomain0.pid
datadir         = /home/mysql0
#log            = /data/mysql0/mysql0.log
user            = mysql
skip-locking
skip-name-resolve
#skip-bdb
#skip-innodb

把配置文件放在 /etc/my.cnf

最后就该启动了
/usr/local/mysql/bin/mysqld_multi start 0-1  这里的0或1是根据配置文件中"[mysqld0]"来定的。
mysql, 端口, 服务器
