轻松描述Windows上安装多个Mysql的步骤_MySQL
问:如何在Windows上安装多个Mysql?
答:具体方法如下:
1.正常安装Windows版的Mysql,例如安装在d:mysql文件夹里;
2.按照常规配置好Mysql;
3.复制备份安装好的文件夹,比如备份到另外一个文件夹,或者命名为“复件mysql";
4.运行卸载程序删除安装的MYSQL和文件夹;
5.把备份的mysql文件夹,重新恢复原来的名字,或还原到原来的位置上;
6.再次运行安装程序,安装在另外一个目录,例如:“d:mysql2"。配置端口为3307;
现在,后面安装的第二个Mysql――mysql2肯定是可以正常运行的,下面让起初安装的第一个Mysql
服务正常运行:
在cmd命令行模式下,进入第一个Mysql的in文件夹。
执行mysql-nt install mysql2命令。作用是为Mysql安装一个服务,服务名是mysql2,你也可以自己改名字,比如mysql5,那么命令就是:
mysql-nt install mysql5
完毕后,在运行里运行REGEDIT,打开WINDOWS注册表编辑器,在HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServices项目找到你刚才手动安装的服务,
我这里是mysql2。打开,修改下面的ImagePath数值。
你一般将会看到"D:mysqlinmysqld-nt" mysql2类似的数值。
在mysql-nt"和mysql2之间加入my.ini的路径信息,格式为:
--defaults-file="d:mysqlmy.ini"
其中粗体部分替换你的正确的路径,
修改完毕后数据数值一般是类似这个样子:
"D:mysqlinmysqld-nt"
--defaults-file="d:mysqlmy.ini" mysql2
确定,退出注册表编辑器。
然后就可以正常启动mysql2服务了,在CMD窗口下输入命令:
net start mysql2
一般应能正常启动了。
如果遇到提示1067错误,请删除你的mysqlDATA文件里的LOG文件,再试。
如果还是提示1067错误,请检查一下--defaults-file="d:mysqlmy.ini"里面的路径是否写错了;
如果还是提示1067错误……请检查一下你的RP……
