 設定檔許可權，將mysql用戶端命令加入路徑

 初始化資料庫，啟動多執行個體，加入開機啟動

 登入不同執行個體，設定管理員密碼

mysql -S /data/3306/mysql.sockmysql -S /data/3307/mysql.sockmysqladmin -u root -S /data/3306/mysql.sock password ‘123456‘mysqladmin -u root -S /data/3307/mysql.sock password ‘123456‘mysql -uroot -p123456 -S /data/3306/mysql.sockmysql -uroot -p123456 -S /data/3306/mysql.sock

 如何再增加一個執行個體？

#多執行個體本質是多連接埠，多設定檔。添加的流程是改配置，改啟動指令碼，初始化，給許可權，啟動
mkdir -p /data/3308/data\cp /data/3306/my.cnf /data/3308/\cp /data/3306/mysql /data/3308/sed -i ‘s#3306#3308#g‘ /data/3308/my.cnfsed -i ‘s#server-id = 1#server-id = 8#g‘ /data/3308/my.cnfsed -i ‘s#3306#3308#g‘ /data/3308/mysqlchmod 700 /data/3308/mysql/application/mysql/scripts/mysql_install_db --basedir=/application/mysql --datadir=/data/3308/data --user=mysqlchown -R mysql.mysql /data/3308/data/3308/mysql startecho "/data/3308/mysql start" >> /etc/rc.localnetstat -nutlp | grep 3308tcp 0 0 0.0.0.0:3308 0.0.0.0:* LISTEN 29518/mysqld
