wget -c https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.28-linux-glibc2.12-x86_64.tar.gz2、mysql数据库脚本上传路径： /opt 包含如下文件(需要修改sql文件中的实例名)
testone.sql
testtwo.sql4、根据服务器磁盘分配情况，创建对应软链接，例如：
mkdir /home/data
ln -s /home/data/ /data5、修改(确保局域网内值唯一)
mysql3306.cnf 的 server_id = 3306
mysql3307.cnf 的 server_id = 33076、注意修改预设的root密码与apps应用连接密码
Multi_PWD="Multi.db"
dbone_appspwd="testone3306"
dbtwo_appspwd="testtwo3307"7、修改testone.sql数据库实例 testone 用户名 testone 及对应的密码 testone3306
create database testone default character set utf8 collate utf8_bin;
grant select,insert,update,delete,create,execute on testone.* to ‘testone‘@‘%‘ identified by ‘testone3306‘;8、修改testone.sql导入数据库时的数据库实例名 testone
$MYSQL_CMD_DIR/mysql -uroot -p"${Multi_PWD}" -S ${DbOneSockfile} --comments testone < testone.sql
9、修改testtwo.sql数据库实例 testtwo 用户名 testtwo 及对应的密码 testtwo3307
create database testtwo default character set utf8 collate utf8_bin;
grant select,insert,update,delete,create,execute on testtwo.* to ‘testtwo‘@‘%‘ identified by ‘testtwo3307‘;10、修改testtwo.sql导入数据库时的数据库实例名 testtwo
$MYSQL_CMD_DIR/mysql -uroot -p"${Multi_PWD}" -S ${DbTwoSockfile} --comments testtwo < testtwo.sql
