MySQL主从复制配置
一台MySQL服务器启动多个端口
/usr/local/mysql-bbs/bin/mysqld --basedir=/usr/local/mysql-bbs --datadir=/usr/local/mysql-bbs/data --plugin-dir=/usr/local/mysql-bbs/lib/plugin --user=mysql --log-error=/usr/local/mysql-bbs/data/product.kimiss.com.err --open-files-limit=8192 --pid-file=/usr/local/mysql-bbs/data/product.pid --socket=/tmp/mysql-bbs.sock --port=3307
/usr/local/mysql-product/bin/mysqld --basedir=/usr/local/mysql-product --datadir=/usr/local/mysql-product/data --plugin-dir=/usr/local/mysql-product/lib/plugin --user=mysql --log-error=/usr/local/mysql-product/data/product.kimiss.com.err --open-files-limit=8192 --pid-file=/usr/local/mysql-product/data/product.pid --socket=/tmp/mysql-product.sock --port=3306
/usr/local/mysql-bbs 下的目录，把mysql相关的内容都移动到这个文件中 bin 中包含/usr/bin/mysql* /usr/sbin/mysql*
