我使用的是手動使用mysql_multi方式安裝mysql5.7.28多實例，安裝過程比較耗時，這裏我編寫了shell腳原本自動化安裝，請你們參考，腳本經測試沒有出現問題，腳本我有二次修改裏面的實例名與變量名，可能存在不一致，請自行對比確認下。腳本中有什麼能夠優化的還請多多指點，謝謝！！如下是腳本中的幾點說明：
一、mysql-5.7.28-linux-glibc2.12-x86_64.tar.gz包上傳路徑： /opt
若是沒有此軟件包，請將此腳本中以下代碼行去掉 # 號註釋，自動聯網下載(下載過程很慢，建議提早下載並上傳到/opt路徑下)mysql

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

二、mysql數據庫腳本上傳路徑： /opt 包含以下文件(須要修改sql文件中的實例名)linux

testone.sql
testtwo.sql

四、根據服務器磁盤分配狀況，建立對應軟連接，例如：c++

mkdir /home/data
ln -s /home/data/ /data

五、修改(確保局域網內值惟一) sql

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

六、注意修改預設的root密碼與apps應用鏈接密碼shell

Multi_PWD="Multi.db"

dbone_appspwd="testone3306"
dbtwo_appspwd="testtwo3307"

七、修改testone.sql數據庫實例 testone 用戶名 testone 及對應的密碼 testone3306數據庫

create database testone default character set utf8 collate utf8_bin;
grant select,insert,update,delete,create,execute on testone.* to 'testone'@'%' identified by 'testone3306';

八、修改testone.sql導入數據庫時的數據庫實例名 testonevim

$MYSQL_CMD_DIR/mysql -uroot -p"${Multi_PWD}" -S ${DbOneSockfile} --comments testone < testone.sqlbash

九、修改testtwo.sql數據庫實例 testtwo 用戶名 testtwo 及對應的密碼 testtwo3307服務器

create database testtwo default character set utf8 collate utf8_bin;
grant select,insert,update,delete,create,execute on testtwo.* to 'testtwo'@'%' identified by 'testtwo3307';

十、修改testtwo.sql導入數據庫時的數據庫實例名 testtwoapp

$MYSQL_CMD_DIR/mysql -uroot -p"${Multi_PWD}" -S ${DbTwoSockfile} --comments testtwo < testtwo.sql
