mysql5.6版本多配置檔案安裝例項
為新例項建立資料目錄並賦權
#建立兩個目錄分別作為兩個例項的資料目錄
mkdir -p /data/application/mysql-multi-instance/
#為兩個例項的資料目錄賦權，避免在初始化資料庫時出錯
chown mysql:mysql -r /data/application/mysql-multi-instance/使用mysql的mysql_install_db例項化資料庫
./mysql_install_db --basedir=/data/application/mysql --datadir=/data/application/mysql-multi-instance/mysql3307 --user=mysql
./mysql_install_db --basedir=/data/application/mysql --datadir=/data/application/mysql-multi-instance/mysql3308 --user=mysql編輯兩個例項的配置檔案
