我使用的是手动源码安装mysql5.7.28，安装过程还是比较耗时，我编写了shell自动安装脚本，请大家参考，脚本我测试没有出现问题，脚本我有二次修改里面的实例名与变量名，可能存在不一致，请自行对比确认下。脚本中有什么可以优化的还请多多指点，谢谢！！以下是脚本中的几点说明：
1、mysql5.7.28软件包(脚本中配置wget下载，如果下载比较慢，可以事先下载好，上传到 /opt 路径下，并注释对应行的wget下载代码，另外源码安装过程比较耗时，安装请耐心等待)，软件包名称如下：
#boost_1_59_0.tar.gz
#mysql-boost-5.7.28.tar.gz
2、两个mysql数据库脚本上传路径： /opt 包含如下文件(注意sql脚本中的实例名)，sql测试脚本名称如下：
#testone.sql
#testtwo.sql
实例dbtwo有添加lower_case_table_names = 1参数
实例dbone没有添加
4、根据服务器磁盘分配情况，创建对应软链接，脚本我配置的路径是/data，根据需要修改，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 = 3307
6、注意修改预设的root密码与apps应用连接密码，根据需要修改使用
#dbone_rootpwd="Dbone.3306"
#dbtwo_rootpwd="Dbtwo.3307"
#dbone_appspwd="dbone3306"
#dbtwo_appspwd="dbtwo3307"
7、修改dbone数据库实例 dbone 用户名 dbone 及对应的密码 dbone3306
8、修改dbone导入数据库时的数据库实例名 dbone
9、修改dbtwo数据库实例 dbtwo 用户名 dbtwo 及对应的密码 dbtwo3307
10、修改dbtwo导入数据库时的数据库实例名 dbtwo
