4 下面就可以初始化数据库了：/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/home/mysql/mydata/data1/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/home/mysql/mydata/data2/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/home/mysql/mydata/data3这样就把一个服务器上所有的数据库都建立好了，在130服务器上也是如法炮制，不过在修改my.cnf的时候要注意一点就是修改server-id，从4以后开始，不要和129服务器的相同。
下面就可以启动数据库了，命令很简单：mysqld_multi --defaults-extra-file=/etc/my.cnf start 1,2,3这就将三个数据库启动好了，可以用下面的语句检查：mysqld_multi --defaults-extra-file=/etc/my.cnf report MySQL server from group: mysqld1 is running MySQL server from group: mysqld2 is running MySQL server from group: mysqld3 is running三 主从配置1 主库建立复制用户：在192.168.202.129上：$mysql -uroot -P3306 -p127.0.0.1 grant replication slave, replication client on *.* to identified by 'repl'; -- 这里限制在局域网内2 从库配置：在192.168.202.129上：$mysql -uroot -P3307 -p127.0.0.1 change master to master_host='192.168.202.129', MASTER_PORT=3306, master_user='repl', master_password='repl', master_log_file='mysql-bin.000001', master_log_pos=0;start slave;
