mysql集成部署

Posted 2020-12-30 Qiao_Zhi

　　

　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)。

　　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)

# Path to installation directory. All paths are usually resolved relative to this.
# basedir="C:/Program Files/MySQL/MySQL Server 5.7/"

# Path to the database root
datadir=G:\\mysql572\\Data

# The default character set that will be used when a new schema or table is
# created and no character set is defined
character-set-server=utf8

# The default storage engine that will be used when create new tables when
default-storage-engine=INNODB

# Set the SQL mode to strict
sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

# Enable Windows Authentication

# General and Slow logging.

#*** 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 1, 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 0 or 2 to reduce disk I/O to the
# logs. Value 0 means that the log is only written to the log file and
# the log file flushed to disk approximately once per second. Value 2
# 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=1

# 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 80% 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 2-3.5G 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 25%-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 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=9

# The increment size (in MB) for extending the size of an auto-extend InnoDB system tablespace file when it becomes full.
innodb_autoextend_increment=64

# 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=8

# Determines the number of threads that can enter InnoDB concurrently.
innodb_concurrency_tickets=5000

# 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=1000

# It specifies the maximum number of .ibd files that MySQL can keep open at one time. The minimum value is 10.
innodb_open_files=300

# When this variable is enabled, InnoDB updates statistics during metadata statements.
innodb_stats_on_metadata=0

# When innodb_file_per_table is enabled (the default in 5.6.6 and higher), InnoDB stores the data and indexes for each newly created table
# in a separate .ibd file, rather than in the system tablespace.
innodb_file_per_table=1

innodb_checksum_algorithm=0

back_log=80

flush_time=0

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                    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:

C:\\Users\\liqiang>mysql -uroot -p -P3307
Enter password: ******
Welcome to the MySQL monitor.  Commands end with ; or \\g.
Your MySQL connection id is 2

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               : 10  WIN32_OWN_PROCESS
        START_TYPE         : 2   AUTO_START
        ERROR_CONTROL      : 1   NORMAL
        BINARY_PATH_NAME   : G:\\mysql572\\bin\\mysqld --defaults-file=G:\\mysql572\\
my.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。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%\'
