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)

#*** INNODB Specific options ***

# innodb_data_home_dir=0.0

# Use this option if you have a MySQL server with InnoDB support enabled

# but you do not plan to use it. This will save memory and disk space

# and speed up some things.

# skip-innodb

# If set to , InnoDB will flush (fsync) the transaction logs to the

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

# willing to compromise this safety, and you are running small

# transactions, you may set this to or to reduce disk I/O to the

# logs. Value means that the log is only written to the log file and

# the log file flushed to disk approximately once per second. Value

# means the log is written to the log file at each commit, but the log

# file is only flushed to disk approximately once per second.

innodb_flush_log_at_trx_commit=

# The size of the buffer InnoDB uses for buffering log data. As soon as

# it is full, InnoDB will have to flush it to disk. As it is flushed

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

# (even with long transactions).

innodb_log_buffer_size=1M

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

# row data. The bigger you set this the less disk I/O is needed to

# access data in tables. On a dedicated database server you may set this

# parameter up to % of the machine physical memory size. Do not set it

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

# cause paging in the operating system. Note that on 32bit systems you

# might be limited to -.5G of user level memory per process, so do not

# set it too high.

innodb_buffer_pool_size=8M

# Size of each log file in a log group. You should set the combined size

# of log files to about %-% 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 needed for the

# recovery process.

innodb_log_file_size=48M

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

# depends highly on the application, hardware as well as the OS

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

innodb_thread_concurrency=

# The increment size (in MB) for extending the size of an auto-extend InnoDB system tablespace file when it becomes full.

innodb_autoextend_increment=

# The number of regions that the InnoDB buffer pool is divided into.

# For systems with buffer pools in the multi-gigabyte range, dividing the buffer pool into separate instances can improve concurrency,

# by reducing contention as different threads read and write to cached pages.

innodb_buffer_pool_instances=

# Determines the number of threads that can enter InnoDB concurrently.

innodb_concurrency_tickets=

# Specifies how long in milliseconds (ms) a block inserted into the old sublist must stay there after its first access before

# it can be moved to the new sublist.

innodb_old_blocks_time=

# It specifies the maximum number of .ibd files that MySQL can keep open at one time. The minimum value is .

innodb_open_files=

# When this variable is enabled, InnoDB updates statistics during metadata statements.

innodb_stats_on_metadata=

# When innodb_file_per_table is enabled (the default in 5.6. and higher), InnoDB stores the data and indexes for each newly created table

# in a separate .ibd file, rather than in the system tablespace.

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.exe                     Services                       , K

mysqld.exe                   Console                        , K

mysql.exe                    Console                          , K

C:\Users\liqiang>netstat -ano | findstr

  TCP    0.0.0.0:           0.0.0.0:              LISTENING

  TCP    [::]:              [::]:                 LISTENING

  TCP    [::]:             [::]:            ESTABLISHED

  TCP    [::]:            [::]:             ESTABLISHED

连接上面启动的3307端口的mysql:

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

Enter password: ******

3.将上面目录安装的mysql安装为windows服务

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               :   WIN32_OWN_PROCESS

        START_TYPE         :    AUTO_START

        ERROR_CONTROL      :    NORMAL

        BINARY_PATH_NAME   : G:\mysql572\bin\mysqld --defaults-file=G:\mysql572\

my.ini mysql572

        LOAD_ORDER_GROUP   :

        TAG                :

        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。至于my.ini的配置在需要啥全局变量设置的时候在这里设置。

补充：查看mysql数据目录可以查看全局参数datadir

show global variables like '%datadir%'
