标签:code offer level ODB 迁移 mysql ISE for int
经常听说mysql数据库是集成在系统中,也一直不太明白集成的概念。今天才明白集成的概念就是将mysql所有的文件放到一个文件夹下放到系统中,也就是将mysql采用目录迁移部署的方式进行安装。在上一篇研究了mysql的数据存储结构之后,也研究了mysql作为目录部署以及安装为mysql服务的方法。
mysql目录安装也就是将mysql必须的一些文件放到一起,然后通过配置文件的配置即可实现。
mysql主要的目录也就是data目录以及bin(存mysql的可执行文件)、lib(存放mysql的dll库)、share(存放mysql的语言支持库)、uploads(一般作为mysql的导出目录)、my.ini(mysql的端口以及其他全局配置文件)。
例如我的目录安装的一个目录:
bin、lib、share、Uploads是直接从mysql5.7的安装目录下拷贝过来的,Data目录也是拷贝的,上篇文章已经讲解过Data目录下存放具体的Mysql的数据库以及表结构与表数据,查看Data的目录如下(是在原来的数据库迁移古来,所以如果集成部署成功数据库应该与原来一样):
my.ini文件:(注意标红位置的修改)

G:\mysql572\bin>mysqld --defaults-file=G:\mysql572\my.ini
新开cmd窗口查看进程信息:
C:\Users\liqiang>tasklist |findstr mysql mysqld.exe 1912 Services 0 228,348 K mysqld.exe 325752 Console 9 208,488 K mysql.exe 325984 Console 9 5,328 K C:\Users\liqiang>netstat -ano | findstr 3307 TCP 0.0.0.0:3307 0.0.0.0:0 LISTENING 325752 TCP [::]:3307 [::]:0 LISTENING 325752 TCP [::1]:3307 [::1]:61234 ESTABLISHED 325752 TCP [::1]:61234 [::1]:3307 ESTABLISHED 325984
连接上面启动的3307端口的mysql:

需以管理员身份执行cmd
C:\Windows\system32>G:\mysql572\bin\mysqld --install mysql572 --defaults-file="G:\mysql572\my.ini"
Service successfully installed.
查看上面安装的服务:
C:\Windows\system32>sc qc mysql572 [SC] QueryServiceConfig 成功 SERVICE_NAME: mysql572 TYPE : 10 WIN32_OWN_PROCESS START_TYPE : 2 AUTO_START ERROR_CONTROL : 1 NORMAL BINARY_PATH_NAME : G:\mysql572\bin\mysqld --defaults-file=G:\mysql572my.ini mysql572 LOAD_ORDER_GROUP : TAG : 0 DISPLAY_NAME : mysql572 DEPENDENCIES : SERVICE_START_NAME : LocalSystem
安装成功之后即可像正常的服务一样使用,启动可以用sc start mysql
删除服务也与平时删除服务一样:
sc delete mysql572
或者采用mysqld方式移除系统服务
mysqld --remove MySQL57
至此mysql集成安装完成,在实际的项目中我们可以采用这种方式将mysql嵌入到系统中进行部署安装。下面附一份实际项目中的my.ini的配置:
