什么集成mysql_mysql集成部署

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。

1.mysql目录安装

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)。

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)

# Ifset to 1, InnoDB will flush (fsync) the transaction logs to the

# disk at each commit, which offers full ACID behavior. If you are

# willing to compromisethissafety, and you are running small

# transactions, you mayset this to 0 or 2 to reduce disk I/O to the

# logs. Value0 means that the log isonly written to the log file and

# the log file flushed to disk approximately once per second. Value2# means the logiswritten to the log file at each commit, but the log

# fileisonly flushed to disk approximately once per second.

innodb_flush_log_at_trx_commit=1# The size of the buffer InnoDB usesfor buffering log data. As soon as# itis full, InnoDB will have to flush it to disk. As it isflushed

# once per second anyway, it does not make sense to have it very large

# (even withlongtransactions).

innodb_log_buffer_size=1M

# InnoDB, unlike MyISAM, uses a buffer pool to cache both indexes and

# row data. The bigger youset this the less disk I/O isneeded to

# access datain tables. On a dedicated database server you may set this# parameter up to80% of the machine physical memory size. Do not setit

# too large, though, because competition of the physical memory may

# cause paginginthe operating system. Note that on 32bit systems you

# might be limited to2-3.5G of user level memory per process, so donot

#setit too high.

innodb_buffer_pool_size=8M

# Size of each log filein a log group. You should setthe combined size

# of log files to about25%-100%of your buffer pool size to avoid

# unneeded buffer pool flush activity on log file overwrite. However,

# note that a larger logfile size will increase the time neededforthe

# recovery process.

innodb_log_file_size=48M

# Number of threads allowed inside the InnoDB kernel. The optimal value

# depends highly on the application, hardwareas well asthe OS

# scheduler properties. A too high value may lead to thread thrashing.

2.启动上面的mysql并且进行连接

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.exe1912 Services 0 228,348K

mysqld.exe325752 Console 9 208,488K

mysql.exe325984 Console 9 5,328K

C:\Users\liqiang>netstat -ano | findstr 3307TCP0.0.0.0:3307 0.0.0.0:0 LISTENING 325752TCP [::]:3307 [::]:0 LISTENING 325752TCP [::1]:3307 [::1]:61234 ESTABLISHED 325752TCP [::1]:61234 [::1]:3307 ESTABLISHED 325984

连接上面启动的3307端口的mysql:

C:\Users\liqiang>mysql -uroot -p -P3307
