建立資料庫目錄並授權

mkdir /data/{3306,3307}/data -p
chown -R mysql.mysql /data/
find /data -name mysql|xargs chmod 700
find /data -name mysql|xargs ls -l

初始化資料庫

• 3306

cd /application/mysql/scripts
./mysql_install_db  --defaults-file=/data/3306/my.cnf --basedir=/application/mysql/ --datadir=/data/3306/data --user=mysql

• 3307

./mysql_install_db  --defaults-file=/data/3307/my.cnf --basedir=/application/mysql/ --datadir=/data/3307/data --user=mysql

啟動多例項

/data/3306/mysql start
/data/3307/mysql start
netstat -lntup|grep 330

連線多例項

cp /application/mysql/bin/* /user/local/sbin/
