在我的前一篇文章中描述了手动安装mysql多实例的过程，今天这一章节，我将它的手动安装过程，编写成脚本来自动安装：
mysql_multi手动部署MySQL5.7.28多实例

以下是脚本中的几点说明：1、mysql-5.7.28-linux-glibc2.12-x86_64.tar.gz包上传路径： /opt如果没有此软件包，请将此脚本中如下代码行去掉 # 号注释，自动联网下载(下载过程很慢，建议提前下载并上传到/opt路径下)

wget -c https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.28-linux-glibc2.12-x86_64.tar.gz

2、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.sql

4、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/ /data

5、修改(确保局域网内值唯一)

mysql3306.cnf 的 server_id = 3306
mysql3307.cnf 的 server_id = 3307

6、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
